TYPE The generator 1s of the vertical shaft, three-phase alternating current, synchronous, designed for direct coupling with hydraulic turbine. The generator is provided with a closed system of ventilation with surface a1r coolers and other auxiliary equipments. The combined thrust and guide bearings are installed above the generator rotor. 2. STATOR 2. 1 Stator Frame (Dwg M202-246338, M202-246339) Stator frame is of steel plate welded construction and splitted in two pieces. Inside the stator frame, stator core is provided, the stator frame has a. sufficient strength and rigidity to withstand not only rotating torque which is induced on running but also faults such as short circuit, etc. should they occur. The stator frame is so designed as to obtain good aerodynamic performance of the air paths and to reduce the cooling air loss to a minimum. The openings 1n the ends of the ftame provide for proper distribution of the cooling air to the end turns and the core. The stator frame is splited 2 pieces to be able to transport. The frame is anchored on the 4 base blocks. The frame and the base blocks are fixed by radially directed knock pins which allow the stator to move by thermal expansion in radial direction without losing the concentricity and take up the torque force. For asist this movement, Molykote has been applied on the contact serface of base block. M905-851852 2/22 Stator frame l,c::::::=====~ u Stator base block Knock oin I· ··· I ~·!olyko te Fig,l Mounting of Stator 2. 2 Fixing Method of Stator Core In fixing the stator core, adiquate numbers of studs are employed and have been so tightened that appropriate tension remain on the studs. ~ In order to withstand sufficiently against the magnetic attractive force under full load operation as well as the maxrmum torque at sudden short circuit, adequate numbers of fixing plates with dovetail groove are welded on the frame, in the line along the studs, and those dovetails secure the studs with the frame tightly, Even if there IS a possibility that the core fatiques after long operation of generator, it rs capable to re-fasten the core with fastening nuts provided on both ends as the same manner as conventional dovetail method. M905-851852 3/22 Fig.2 Stator Frame Fig.3 Stacking of Stator Core M905-851852 4/21 2. 3 Stator core The stator core consists of high grade, silicon steel plates of 0.5mm thickness. The punched core plates are fan shaped. After punched, thermosetting varnish is applied to both surfaces of core plates to minimize eddy current loss. The fan-shaped_ core plates are stacked piece by piece and are laminated half lapped with studs provided on stator frame as quide and fixed tightly by means of end plates. Duct p1eces are provided between every stacked core blocks with suitable intervals to from air ducts. The laminated stator core, especially the parts near by the air ducts, are fully clamped so as not to be affected by vibration or magnetic pull during operation. The stator core laminations are completely stacked, pressed and fixed to the stator frame with studs and fixing plates. When the stator expands radially through temperatire r1se, high internal stresses and wave deformation can easily occur in the core. The following measures were taken with this machine to prevent this: (1) The stud holes in the core are made elliptical and the suitable clearances between core plates and studs are provided in radial direction to allow the radial movement of stator core at thermal expansion without any restrictions. (2) Radial torque p1ns are used to allow the radial movement of thermal expansion of stator frame. M905-851852 5/22 4 2 3 Fig, 4 Stator Core 2. 4 Stator winding (Owg. M900-485845, M140-246047) 1 4 Stator core Stator frame Stud Fixing plate Fastening nut s~ction A-A The stator winding is of the single turn coils and the double layer bar type. The stator windings are insulated with class "F" insulation as defined by the I EC standard. The slot insulation of stator windings are so made that a required thickness Of mica tape is wound in half lap continuously throughout the entire length of the winding and then vacuum impregnated with epoxy resin (F-resin). Since the insulation of coils is a dense, homogeneous, free from a1r pockets, the coils have extremely excellent electrical and mechanical feature. The slot portions of the coils are treated with the semiconducting paint and the overhang portion of the coils are treated with the non-linear resistive paint to prevent the corona. The strands are of annealed copper, free from splinters, flaws, rough spots, or sharp corners. The strands are insulated by glass and transposed by Reabel method to minimize losses and heating. M905-851852 6/22 Cod The coils are inserted in the slots which are covered with slot liners of carbon fleece sheets. The number of sheets to be laminated is decided so that the bars are fixed tightly in the core. The stator coils are tightly wedged In the slots. The wedging system shall be refered to Owg. No M900-838965. The coil end joints are subdivided into 4 (four) portion and are connected by means of silver aloy brazing respectively. The coil ends are insulated with mica-glass boxes filled with quartz powder and epoxy resin. The stator coils are adequately supported and braced to prevent from dropping in the slots and to withstand the full stresses developed due to short circuit fault conditions.

ROTOR The rotor consists of a ma1n shaft with rotor hub, an auxiliary shaft, a thrust block, a slipring, a brake ring, two fan, a rotor rim and poles. 3. 1 Pole and Pole Key (Owg. M120-246156, M016-246858) The poles are constructed from high-tensile steel laminations 1. 6 mm (0. 063u ) thick which ara tightened together by pins.

Slipring Maintenance Item Cleaning of sliprings Maintenance Points to be inspected State of Cleanliness Surface of during long-sliprings term shutdown Maintenance/inspection method (1) Remove any oil, dust, or brush particles from the sliprings, brush, and brush holder. (2) Wipe the sliding surface of the slip- rings with a clean cloth. Do not use an oily cloth. (3) If there is oil on the sliding surface, wipe it off with a cloth moistened in a volatile solvent (unleaded gasoline, benzine, alcohol, etc.), then wipe it with a dry cloth. (4) Clean the sliprings especially carefully after bedding in a brush or resurfacing a slipring. When the generator will be shut down for a long time, the brushes should be lifted, or a good thickness cardboard shall be inserted between the brushes and sliplings to prevent the sliprings from rusting. During sound operation, graphite-impregnated film will be formed on the sliplings. If it has a uniform, unstreaked coloration, it must not be removed, because this film is essential for good sliding. Grinding of sliprings Eccentricity (1) If there are scratches, rough or uneven or other departure from circularity places, or spark burns on a slipring, lift the brush and grind the slipring with an abrasive block or emery paper (about No. 320).

I !Eccentricity I (1) If a slipring departs badly from a or other departure from circularity circular shape due to eccentricity, waves, or surface roughness, it should be resurfaced with a cutting tool (skimmed). (a) The skimming is best done by mount- ing the rotor on a lathe. If this is not possible, the skimming shoul~ be done with the rotor mounted firmly on a planing support. (b) The cutting machine should permit both radial adjustment and axial feed of the cutting tool. Make sure that the part that holds the cutting tool is accurately aligned in paral- lel with the rotor axis.

This tolerance refers to the deviation of the center, that is, half of the instrument reading of the deviation. Brush marks on the slipring surface are a common occurrence. They may equally spaced at the same interval as the brushes, or they may be irregularly spaced and extending in the sliding direction. These marks prevent good electrical contact between the brushes and sliprings and can cause sparks. (1) Brush marks spaced at the same interval as the brushes occur mainly when the generator is stopped, and are probably the result of high humidity or severe changes in the ambient temperature, For this reason, it is advisable to lift the brushes when the generator is stopp- ed for a long time. / Item Change of slip ring polarity Points to be inspected Maintenance/inspection method If the marks are particularly bad, they should be completely removed with an abrasive block or emery paper. (2) When the marks appear in rows that extend in the sliding direction, the cause may be contamination of the slid- ing surface by dust or gas, worn-out brushes, inadequate brush pressure, uneven brush pressure, sticking due to abrasion particles in the brush holders, eccentricity or roughness of the slip- rings, a bad contact due to a brush defect, etc. Investigate these possible I causes and study the problem, Since I these marks can cause sparks or un- 1 balanced current flow, they should be removed with emery paper or an abrasive block. + + I 1+1 +1 J -+ --t--------rl-:-+-rl-- --1::...--+------'--'-+_,_1 __ K Connection before change >----- _r~ + J _+ __ +i + 1+1 K + +l I Connection after change IM500-810155Afi'6 I E t; Item Points to be inspected 3. Brush Maintenance Item Replacement of brushes Points to be inspected Degree of wear Maintenance/inspection method Slipring surface damage in ~ synchronous generator tends to occur on one of the two rings. This is especially true when the machine is used in an environment with high humidity or extreme temperature changes, or when there is oil on the rings. To reduce surface damage, the polarity should be switched about once a year to equalize wear on the rings, When the problem is parti- cularly bad, the polarity should be switched before heavy damage occurs, To switch the polarity of the sliprings, switch the connection tabs that connect the brush holder supports to the leads as shown in the drawing above. Maintenance/inspection method The brushes tend not to wear evenly, and the wear depends on the polarity, so be careful not to let the brushes wear out. Worn-out brushes can lead to sparks due to inadequate brush pressure, inadequate pig tail length, or excessive play of the brushes in the brush holders, (1) The brushes have a wear allowance of 25 mm, They are painted in two colors,. with the arm end colored red and ~vhi te. When the white part is completely inside the brush holder box, it is time to Item Brush fitting Points to be inspected Contact condition ,. (2) (3) Maintenance/inspection method replace the brush. Replace the worn-out brush with a brush that has already been bedded in. If a brush has been used s.o long that it has become impregnated with oil, or the pig. tail mounting fixture is loose, replace the brush. (1) A ne<v brush has a flat sliding surface, which must be bedded in to fit the curved surface of the slipring. (See Fig, 1) (a) To bed in the brush, first insert a sheet of rough emery paper (appro- ximately No. 120) between the brush and the slipring, hold it against the slipring surface, and draw it back and forth (to the left and right) acr~ss the brush until the brush comforms to the curved slip- ring surface. Do not let the edges of the brush become rounded. (b) Next switch to a finer grade of emery paper (No. 220 or No. 320) and repeat the process to make the brush conform accurately to the slipring surface. (2) After bedding in a brush, clean the brush, brush holder, slipring, and insu- lator surfaces to remove all brush dust and emery dust, (3) Check that the brush moves smoothly inside the brush holde~. (4) Take advantage of times when the genera- tor is stopped to bed in a supply_of Item Points to be inspected Maintenance/inspection method spare brushes to use for emergency replacements while the generator is running, (5) When replacing brushes while the generator is running, replace the brushes one at a time, taking ample time and care to prevent short-circuit accidents. (6) The sliprings are spaced wide apart to allow room to work, but you should still wear shoes with rubber soles and rubber gloves, and try to avoid exposing your arms or other parts of your body.

Fig. 2 (Bad) Brush sliding (1) When 1/3 or more of the brushes are sound and sparks replaced, after a thorough cleaning, a bedding-in run should be made. First run the generator for one or two hours with no load, then run it with a light load. Switch to a full load when at least 80% of the sliding surface of the brushes is making contact. (2) If a bedding-in run cannot be carried out, take extra care when bedding in the brushes with emery paper. (3) After resurfacing a slipring, either by grinding or with a cutting tool, carry out a bedding-in run for as long as possible to let a carbon film form on the slipring surface. (4) Pay particular attention to the brush sliding sound, sparks, and vibration after replacing brushes. Improper bedding in can cause various unfavorable conditions during operation after brush replacement. Item Degree of brush wear Grades of brushes and intermixing Pressure adjustment Points to be inspected .Initial brush dimensions Maintenance/inspection method When electrographite carbon brushes are used that have a good current distribution and film formation characteristics~ they should '.rear an average of 3-12 nun per 1000 hours. (1) Never use different grades of brushes together. (2) Differences in the physical character- istics and sliding characteristics of brushes can lead to accidents. For this reason, even when the brushes are of the same grade, try to avoid using new brushes together with brushes that have been in service for a long time, Consult the manufacturer before replac- ing brushes with spare brushes of a different grade, and be sure to remove all brushes and replace them all with the new type. The mechanism is constructed so that brush pressure adjustment is not required. The carbon film on the surface of the sliprings stabilizes wear on the brushes. To see how brush wear depends on running time, the initial height of the brush aft~r the completion of the bedding-in run should be measured and recorded. I M500-810155A1?(o I 4.

For stubborn dirt, use a clean cloth or a nonmetallic brush, Remove any oil, etc. with a cloth soaked in benzine. Take out the brush before cleaning the brush holder. (1) When installing a new brush holder, check that there is a gap of approxi- mately 2 mm bet~veen the bottom of the brush holder and the surface of the slipring. (2) Install the brush holder at the correct angle to the slipring surface, and make sure that the brush holders and slip- rings are centered on the same point in· the axial direction.

Introduction The F resin/F insulation system applied to the stator winding have very excellent electrical and mechanical . features as well as moisture resistance and chemicals resistance. Since the stator windings are manufactured under a_strict quality control system, the stator winding will scar~ely be damaged under normal operating conditions. However, the coil insulation may be mechanically·d~aged due to external causes (unexpected accident, contact of incoming substance, ingress of foreign substances, etc. during transportation, for example) and the insulation breakdown may be occured due to a mechanical damage. For repairing such an insulation damage, a suitable remedial method must be decided according to the damage conditions. 2. Survey before repair and decision of remedial method a. Check the damaged position, extent· of damage, and range of damage by visual inspection. b. When the damaged position cannot be found by visual inspection, the damaged position wiil be found by a non-destructive method (potential measurement by current flowing test using a low voltage and a large current, megger test, etc., for example). c. It is desirable that the dam~ged position is separated from other normal sections electrically and the dielectric strength test of windings is performed in nor~al sections in order to confirm that normal sections are not damaged. Dielectric strength test value =· Rated voltage x 1.5 / 1 min. fv1 0 95-850 2 6 7 .- 3. Damaged position of stator coil and remedial action The damaged positions of the stator coil can ro~ghly be divided into the following three cases. (See F~g~ 1). a.

Repair 4-1 Repair of insulation dam~ge of ST lead Regarding the ST 1ead damage, a mechanical dam~ge (insulation damage due to the collision of a substance, insulation breakdown due to centralized stress, etc.) and an electrical damage (ground fault caused by a mechanical damage, interphase short-circuit, etc.) may be considered. a. Survey of damage portion If the damaged portion is located at the.upper leads, it may be repaired locally. However, it is difficult to repair a damage at the M095-8SO?G7 ' lower leads. If a damage is located near a lead clamp, the lead clamp must be disassembled. It is necessary to disassemble the leads, the lead clamps and the other parts, \vhen the repair work is· not possible without disassei!'bly. · Observe procedure in (p) I if disassembly is required. b. Disassembly procedure (PleasE? refer to Fig. ~;) 1) Loosen screws of the support block and dismantle the support block. (The conductors are dis- connected from the conductor part.) 2) Cut the bind tape of the spacer, and dismantle the spacer. · ·3) Chip the insulation at the flexible conductor connection part, and disconnect the lead at the one side of flexible conductor by using a_ gas torch. 4) Dismantle the leads one by one, starting from the upper leads to damaged lead. c. D iclsion Cf re-pair insuldtion The dielectric strength at the repair part should be equal to or higher than that remaining part. The damage may sometimes be not limited to the insulation and extend to the conductor. Accordingly, if the conductors is extremely.melted and the conduction area of conductors is reduce4, the conductors must also be replaced. This manual describes the insulation repair, assuming that the conductors are not so damaged. When the reduction of conduction area caused by m~ting is less than 10%, it is not necessary to replace the conductor. The repair procedure is shown in Figs. 3 and 4. MOSS-850237 ( ' '-. Stud Support block insulation Protector Fig. 2 Disassembli~g procedure of stator winding lead d. Repair procedure 1) Clean the vicinity of the repair part Wipe the dirt on the insulation surface in the vicinity of the repair part by a solvent. 2) Repair of da~aged part Chip the insulation at the damaged part accord~ng I M095-850267 to the instructions shown on Fig. 3. Be careful not to damage the conductors as much as posiible. 3) \vhen the conducfor is damaged, repair the con- ductor surface by using a file or a sandpaper so that the conductor surface should be ~ree from burrs and melted residue of copper and should have smooth surface. 4) Protect the chipped portion dust, oil mo~sture, etc. that cause unsufficient adhesion under subsequent resin treatment and the dielectric strength deteriorates. 5) Insulation taping and resin treatment Perform taping carefully with coating resin as shown in Fig. 4 so as to be free from wrinkle of ~he taping and resin voids. 6) Drying of repair portion The repair portion must be dried up under condition of 50°C (130°F) and more than 3 .hours. If the resin is not hardened, the dielectric strength will be lower. 7) Reassembly (See Instruction ~anual for site assembling) 8) Tests after repair Measure the insulation resistance and carry out the dielectric strength test after repair to check whether repair works is sufficient or not.

However, if the coil end is · electrically damaged, it affects over a .wide range, and the damage cannot often be repaired by a simple ,local work. a. _Survey of damaged portion The following inspection should be carried obt. 1) Whether the damage is limited to the insulation layer only or not. 2) Whether the conductors are damaged due to melting or not. 3) The number of damaged coils. 4) The darr.aged coil is front one or bottom one. 5) Whether the damaged portion is accessible for repair or not. b. Decision of repair method ~·~hen the damage is limited to the insulation layer of the front coil and there is no such a defect that may cause a short-circuit failure between conductor wires and the damaged portion, the local repair is possible according to procedure in item (c). When the bottom coil is damaged, local repair may be possible depending upon damaged places, however local repair work without dismantling is impossible in most cases. A repair work other than described above should be executed after dismantling the coil according to clause 4-3. fviO 95-85026 7 .- c. Insulation repair procedure Perform the repair work according to clause 4-1. Be careful not to dam~ge the internal conductors during repair work.

Repair procedure 1) Cleaning of repair part and.its vicinity.·: Remove dirt from the insulation surface in the vicinity of the repair part by usi~g a solvent. 2) Repair of dam~ged portion Chip the insulation of the damaged portion according to the instructions .shown. in Figs. 6 and 7. Never scratch the conductors. For_this purpose, a part of the bottom layer may be left undone. 3) Protect the chipped portion from dust,· oil, moisture, etc. that cause the unsufficient adhesion under the subsequent.resin treatr:1ent and the dielectric strength deteriorates. 4) Insulation taping and resin treatment Perform taping carefu1ly with coating resin as ~ shown in Fig. 7. Be careful not to wrinkle the tape nor leave resin voids. 5) Drying of repair portion The repair portion ~ust·be dried up under con- dition of 50°C (130°F) for more than 3 hours. If the resin is not hardened, the dielectric strength will be lower. 6) Test after repair Measure.the insulation resistance and carry out the dielectric strength after repair to check M095-85026 7 .- whether repair works is sufficient or not.

This clause describes the coil exchange procedure. If the number of spare coils is insufficient whe:p· the slot part or the vicinity of the slot outlet is dcpnaged or a coil conductor is not reusable, new coils should be obtained from the maker. a. Survey of damaged portion For checking and surveying the dam~ged·portion, find out damaged coil by using a non-desctructive method (megger test, measurement of potential in a current flowing test using a low voltage and a large current, for example) as much as possible, referring to·the stator winding diagram. If an insulation dam~ge (an earth fault) is detected in a slot, the insula~ tion damage of the coils often causes insulation damag~ of the another one in same slot, and both front and bottom coils are damaged concurrently. __ In addition, when these front and bottom coils are damaged, the core may often be melted. It is, therefore, necessary to disassemble the coils and survey the internal ·damage conditions in details after locating the damaged part. b. Disassembly of coils for replacement b-1 Cautions on disassembly 1) Be careful so as not to scratch coil insulation other than damaged coils when disassembling the coils. 2) In case of front coils, the damaged coils can be pulled out after disasse~bling a required place. However, the bottom coils cannot be pulled out, unless the upper coils which overlap M095-850267 the bottom coils are fully pulled out.

Repair of core The core may often be damaged concurrently t~gether with the damage of the coil insulation in slots. ~f the core is repaired incompletely, it is locally heated during operation to be conducted later, causi~g the coil insulation to be damaged again. Thus, the core must be repaired completely. If the core is damaged seriously, it is recommended to decide a repair method by consulti~g with the maker.

Usually the cleaning should be used by item 5-l, however, if the contamination of stator windings is not taken away by the cleaning 'procedure of item 5-l, the cleaning procedure of item 5-2 should be used. 5-l Cleaning with wasted cloth ..• . ~ '". Wipe away the dust on the surface of stator windings with wasted cloth which is dipped in the cleani~g liquid and is wringed lightly. When dust is in narrow space or hole, use rod which is wound with wasted cloth on one end. The wasted cloth should be frequently cha~ged to new one or should be washed in the cleani~g liquid when it becomes dirty. 5-2 Cleaning with blower Blow.the cleani~g liquid to the contaminated parts of stator windings using_compressed air,-and wash away the contaminated dust. The wasted cleaning liquid are received by vinyl sheets or-pans, and lead to the outside of stator frame. Drying of stator windi~gs after cleaning. The drying temperature should be 100-130°C, and the drying period should be 10-16 hrs. a. Cover the stator using non-inflammable sheets~ and blow hot air to the stator _unsing the 3-4 hot blowers placed equal pitch. b. Take care not to remain any inflammable materials such as paper or wood inside of the cover. c. •rhe hot· air from the blower should not be blown directly to the coil insulation, in order to avoid local heating. 1 fv\095-85026 7 -- d.

(2) By using a scraper, adjust the clearance for the limit specified in the instruction manual of the generator. (3) Measure the clearance at 8 positions equally divided on the shaft. (4) Fitting work on the guide bearing and the shaft, is not required. 1-2 Division Method (In case of se·gmental Guide Bearing) A. Setting Method for Guide Bearing Gap After lowering the rotor, the bearing gap shall be adjusted by the cotter. (Refer Fi~. 1) (1) The distance "X" between the shaft and the datum surface for centering of the bearing oil tank should be measured at the 4 positions divided equally around the circumference of the shaft. It should be confirmed that the center of the shaft is at the center of the datum surface before center- ing. The allowable value of deviation shall not exceed 0.03 rnrn. Should the alignment is beyond the allowable value,. the respective parts shall be removed, and the location of the shaft. adjusted by pushing the shaft with the jack. (2) With the cotter shall be inserted, the head of the cotter should be hit gently until the clearance between the bearing gap and Point-"A" is 0 mm. IM960~810156 Ys E When doing this, it should be ensured that the location of the shaft has not be moved. (3) Head length of the cotter "H" shall be measured with depth gauge and recorded. (4) Nuts are provided for the screw part of the cotter. The cotter is raised by revolving the nut until the bearing gap is at the specified value (G rnrn) shown in instruction manual.

PROPER TIGHTENING TORQUE OF GENERALPURPDSE BOLTS AND NUTS 1 ) RULES OF TIGHTENING TORQUE General bolts and nuts shall be tightened with the proper tightening torque as specified in Table 1 and 2 as a rule. At actual tightening work, apply the operation force ·appropriate to the length of the spanner apecified in the ralation between tightening torque and operation force shown in Fig, 1. Notice is required in the application of these table as follows (1) These tables provide the proper tightening torque for hexagonal head bolts and hexagonal nuts of SS41 and SUS304 and for hexagonal socked head bolts of SCM prescribed in JIS stadard or for the equivalent in mechanical characteristics, and the tables cannot be applied to other bolts and nuts of different characteristics. (2) The values in Table 1 are the standard values applicable in case that the contact surfaces are coated with seizure preventives such as white zinc paint or MDLYKDTE and the tightening is carried out without impacts on the spanner. Accordingly, the values are not applicable to other conditions. (3) The values in Table 2 are applicable in case that the contact surfaces are not coated with oil or chemical mateials influencing the coefficient of friction. Be careful not to confuse with Table 1. (4) In case that tightening torque is specified particularly in the drawing or instruction of each work, the work must not be carried out according to Table 1 or Table 2.

Further, pay attention to avoid as much as possible screw tightening work at a dusty place. (2) Application of seizure-preventives As a rule, apply white zinc paint ( generally called "White Paint" ), MOLYKOTE, etc. uniformly both on the female thread and on the male thread after cleaned perfectlY. (3) Screw fitting before tightening Turn a screw into a hole by hand till the screw rs fully inserted making sure of no excessive play or tightness of the inserted screw. Then tighten the screw with a spanner. (4) Sequence of tightening for a number of bolts and nuts Tightening should be done in diagonal positions. Generally, even if a set of bolt and nut is tightened at one position with the prescribed tightening torque, it is apt to become loose when adjacent set of bolt and nut is tightened, and therefore, it is a rule to fighten then according to the follwing sequence : a) In case no packing is used on the tightening surface· · To be tightened twice. b) In case packing IS placed on the tightening surface · · To be tightened three times. M905-851857 9/10 c) In case of oil-, water-, air-tight, etc · · To be tightened four or five times. Primary tightening should be done with a tightening torque of 70---80% of the prescribed v a 1 ue. Example Screw tightening work for eight screws distributed at equal interval on a circumference with a packing on the tightening surface : Tighten the screws according.on the sequence from 1 through 8 as shown below, and repeat tightening work three times. 7 ' 4 3 6 8 2 M905-851857 10/10 Instruction Manual· OPERATI~G CO\SIDERATIO\S ~-' ' . • . --•. ,.,-.•• -: .. ." -. • '-..,. ~-·· ~ -· .. •.:;... . -· .. -.~ ~ .~ .... c..· .. -~-"r~..r'."" --'!#IF,._ .0 ?

Thrust Bearing High Pressure Oil System 1) The generator equips with a bearing high pressure oil system to life up the rotor during normal starting and stopping. 2) The minimum permissible rotating speed of unit at which pump operation commence or termination is 70 r.P.m. regardless of the bearing temperatures. 3) When the bearing high pressure oil pump IS In failur~ the considerations shown in the table below should be taken for starting the unit. Continuous stopping Special consideration before unit starting period of the unit Less than 1 week · The unit can be started without jacking the rotor irrespective of the bearing temperature.· 1 More than 1 week Before starting the unit, Rotor should be jacked up by I the Rotor jacking system and made sufficient oil film on the thrust bearing surface to start without detrimental effects. Method is as follows : Jacking up height 1/4 II ~5/16" (6~8 mm) Holding time 30 Minutes Detail operating method of jacking system are shown on the Chapter 9 of Part 2 (Auxiliary equipments). 4) If the failure of the bearing high pressure oil pump occurs during unit stopping sequence, the bearings permit a stopping sequence to be completed regardless of the bearing temperature values. 5) However, it is undersirable to start and stop the unit repeatedly while the bearing high pressure oil pump 1s 1n failure. So, it is advisable to repair the pump as soon as possible. 3. Cooling water control system Closed circuit system is used for this cooling water control system. As shown in Fig-2, this system is disigned so the cooling water is circulated by a pump provided in the cicrcuit through each cooler without being drained out. This unit is equipped with a pressure control valve, and a cooling control valve which is provided only in the air cooler discharge line. M905-851846 3/4 The pressure control valve is provided to maintain the pressure (max. 75 psig) of cooling water which flows in the bearings and air coolers.

(' 3. INSTALLATION 3.1 All vents and drains supplied with coolers should be in place when coolers are installed. ' 3.2 All pipe joints, drain cocks and coverplates must be tight. CAUTION: All bolts in the waterboxes must be tightened up evenly before filling. , 3.3 Make certain that the· entire tube side supply system is clean before starting operation to prevent plugging possible of the tubes. The use of strainers in settling tanks and pipe lines is recommended. 3.4 Care must be taken to minimize thermal shock when putting the unit in operation. This generally means admitting the process fluid at a low rate and gradually increasing the flow to design rate. Start fans as temperature exceeds design. 3.5 When starting the Coolers, open the vent connections until all the contained air is released. Repeat as necessary. · 3~6 A slight slu.dge or scale coating on the inside of the tubes greatly reduces the heat transfer capacity of the Coolers. A reduction in performance usually indicates cleaning is necessary. If the outlet air tempera.ture begins to rise and the unit has been checked for air binding, then it becomes necesary to clean the Cooler. (Since the difficulty of cleaning increases rapidly as the scale thickens, the intervals between cleaning should be governed by the conditions of the tube side fluid and the facilities available for cleaning.) 3. 7 Dirt on the outside surface of the tubes also greatly reduces the heat transfer capacity of the Coolers and sl)ould be removed. Instructions for cleaning the outside are given in paragraph 5. . ' :3.8 When shutting down the unit, stop the air flow first, and turn the tube side fluid off last. 3.9 When cooler is shut down, drain it thoroughly to eliminate the possibility of sludging or of freezing in cold weather. If absolute drying is required, final traces of fluid can be removed through the drain connections using a suitable vacuum cleaner and adapter. Surfaces can then be dried to reduce corrosion by forcing warm, dry air through the same-connections. ·• . . . .

MAINTENANCE CAUTION: -No maintenance should be done on the coolers until personnel are certain that all pressure is off the equipment and the unit is drained. 4.1 A regular cleaning and inspection schedule should be adopted. The schedule should ensure that the coolers are cleaned in the late spring before the air or fluid temperatures increase to summer levels. Inspection should be done giving special attention to tube side leaks. A maintenance and inspection timetable is to be determined by the customer and should take into consideration the cooler conditions and facilities available. 4.2 When the unit is shut off a,nd drained, the cove·rplates can be removed for cleaning and inspection of the tubes. 4.3 It is good practice to replace the gaskets each time the cooler is opened. Prior to removing cover plates, therefore, it is recommended that an adequate supply of the gasket material named on the cooler drawing be readily available. In replacing the coverplates, clo not tighten the bolts until satisfied the gaskets arc properly seated. This precaution will eliminate a major cause of leaks. Loose or unevenly tightened bolts, a worn gasket or an improperly seated gasket can cause water leakage from the vicinity of the gasl<ets and should be watched for. 5. TUBE CLEANING 5.1 Tube Cleaning -Outside 5.1.1 When accumulated dust and light residue adheres to the finned surface this may be removed by simply using a long bristled brush . A coarse bristled brush may damage the fins. Such brushes can easily be fitted with long handles to reach overhead installations. Care should be taken to prevent 5.1.2 damage to the finned surface. When blow.ing with air or brushing fails to remove dirt accumulations as in the case of caked material on the finned surface, steam should be considered · next. At steam hose with a pressure above 20 lbs. will usually remove caked dust. Grease too, can usually be dissolved by steam. Steam should be applied from the discharge side of the coil for best results. 5.1.3 If the above two methods do riot remove adhered dirt, a cleaning solution ca,n be used with steam. This combination of cleaner and steam can be applied directly to the cooler with guns made especially for tlmt purpose. This ' equipment would normally be available from reputable suppliers, who will also provide the solvents and instructions for their use. 5.2 Tube Cleaning-Inside 5.2.1 · Proper cleaning equipment can be obtained for these coolers. These include a expanding cleaner which has cutting blades that spin outwards when the tool is revolved, and an M 760 -s s1sse. 'Ys !lat!illt nn..11: l.NL>TA .l1U.N A.N1J roAlN l.t.NA.NLa:.

If verv hard dep'?sits of scale cannot be removed with the above equipment, ~ ' Conical Cutter may be used with caution. The Expanding Brush Cleaner should be satisfactory for most inside tube fouling . encountered. Stubborn scale can be removed with the Expanding Cleaner. Very heavy, hard deposits can be attacked and broken up with the Conical Cutter, and then finished off with the other cleaning-elements. Tubes should be washed out with v·:ater after cleaning. CAUTION All tube cleaning tools mentioned above should be used with extreme care. Do not force. the tools through the tubes. Rough handling can result in permanent damage to the tube walls. 6., MAINTENANCE TO LEAKING TUBE JOINTS 6.1 If tubes become loose in the headers, they can be tightened with proper Tube Rolling Expanders. 6.2 It .is recommended that tube rolling be done only by mechanics with previous e1.1>erience. and proven skill. The mechanic should be very careful in using the expander. Excessive rolling thins and may work harden the liner tubes, and result in permanent leaking joints. - 6.3 To remove a bell end type tube, (when applicable) relax the ·clamping bar assembly, then collapse the bel:! with a chisel or screwdriver driven . against the protruding portion of the bell until it is loose in the tube hole. Then using a shouldered drift pin, the tube may be driven out from the samll end. Clean up the tube holes to remove any tube metal and check inside surfaces for evidence of scratches. Any marks in the tube sheet holes must be removed with a reamer to ensure a tight joint. Install the replacement tube so each end protrudes through the tube sheet (up to 3/16") and rolier expand with conventional tube expanding equipment. Return the clamping bar assembly to its original position to secure. the tube bundle. CAUTION Do not expand the tube beyond the tube sheet. DO NOT EXPAND TUBES THAT ARE NOT FOUND TO BE LEAKlliG. These instructions are intended only for general use. If any difficulties are encountered with these coolers in particular installations, it is recommended that Unifin International, London, Ontario, Canada, be contacted for specific instructions or consultation before attempting to remedy the situation concerned.

INTRODUCTION Model T-4X level switch is a detector capable of operating at an arbitrary liquid level to detect a change in the level of liquid such as water and oil. It finds application chiefly in oil reservoirs of hydropower warter wheels, generator top and bottom bearings, and other places where changes in liquid level are relatively small. 2. EXTERNAL WIRING Highest Level 2-1 25APF screws serve as through portions. 2-2 M4 screws are used to fix the terminal board. 2-3 Terminal numbers are related with liquid levels detected as shown right. In the case of using a DC power source, be sure to connect all "+" poles to even numbers. Lowest Level M700-851841 2/4 3. CONSTRUCTION AND OPERATION The motion of a float which follows up the liquid level ·is transmitted through a tape directly connected with the float to a pulley in the detector and, hence, to a reduction gear to rotate a camshaft and thereby to turn on and off an independent setting microswitch. As the transmitting tape is graduated according to the specification, the liquid level can be read through a peephole. 4. ADJUSTMENT OF DETECTOR (SWITCH MECHANISM) 4-1 The position at which the switch turns on can be freely changed on the site, which permits fine adjustment of the diagram preset in accordance with the specification. 4-2 Adjustment of cam plate Adjusting cam gear A can be made to rotate freely by pushing gear B until it is released from engagement with gear A. To lower the set position, turn the gear clock wise. To raise the set position, turn the gear counterclockwise. Then read the scale referring to the variable index plate to check the adjusting stroke. After the adjustment, restore the engagement of adjusting gears A and B. 4-3 When touching the gears, be careful to keep off dust and dirt. M?00-851841 3/4 5. ADJUSTMENT OF INDICATION The level switch is set to conform to the specification before shipping. When readjustment is needed, proceed as follows. Remove the cover and turn the adjusting screw, and the pointer will shift. Adjustment can be made within the peephole range of ± 5" (127mm). To change the specified level in the rising direction, turn the screw clockwise and, in the lowering direction, turn counterclockwise. Zero on the scale is the specified level.

A level limit switch for liquids and bulk material (not to be used in explosion-risk areas). Our comprehensive probe program permits level detection -in aggres.sive materials -at high pressures or in vacuum -at high and low te.mperatures -in coarse-and fine-grained bulk goods -in highly and poorly viscous liquids -in materials with a tendency to form deposits See the brochure "probes 1.3" for suggestions on the selection and installation of the appropriate probe. What constitutes the complete measuring equipment? The complete measuring equipment consists of the NIVO- TESTER FTC 420, a suitable probe and the electronic insert EC 61 Z (measuring transmitter), which is installed either in the probe head or (in the event of high temperatures in the vessel) in a separate housing. You can connect relays, CO!ltactors or electrovalves for control systems or alarms to the output of the NIYOTESTER F1C 420 (potential-free change-over contact). How does the capacitance limit switch NIVOTESTER FTC 420 operate? The probe and vessel (or the earth tube of the probe) form a capacitor, whose capacitance is altered by the level. The electronic insert converts the capacitance change into a voltage signal which actuates the output relay in the NIVO- TESTER FTC 420. The internal resistance of the electronic insert EC 61 Z is very low so that interferences on the signal line virtually does not affect the NIVOTESTER FTC 420 circuit. A light-emitting diode indicates whether the mains voltage is available (operation readiness display J, while the position of the output relay is displayed by a second LED. See fig. 8 for the function of the relay and of the LEDs in relation to the fail-safe mode and level. What are the advantages of the NIVOTESTER FTC 420? Mechanical advantages The NIVOTESTER FTC 420 in its narrow MINIPAC housing is ideally suited for switch cabinet installation. It is com- pact -only 50 mm in width -can be set flush on a symmetrical 35 mm standard rail and can easily be wired thanks to.the terminal blocks situated at the front. '!'e also supply a wall fastening for mounting a single mstrument. For open-air installation, we have a protective housing IP 55 with a transparent cover for two instruments. NIVOTESTER FTC 420 E 05.82.02/2 a Do you want to exchange an instrument? There is no pro- blem. The wiring need not be removed since the terminal blocks can be lifted off the contact blades. Once you have snapped the new instrument on the rail and replaced the terminal blocks, the correct safety mode is in operation again because the bridge to choose the safety mode is situated on the terminal block. The few calibration elements (a switch for range and an adjusting knob for calibration) are located behind the re- movable front panel and are thus easily accessible yet pro- tected against unauthorized interference. Electric advantages The well tried and tested three-conductor technique is not new but, the low internal resistance of the electronic in- sert EC 61 Z makes it so interference-free that commerci- ally available installation cable is sufficient for signal trans- mission between the probe and the limit switch. Conductive deposit on the probe? No problem for the NIVO- TESTER FTC 420 with the right probe (partially isolated but with long insulation) and a wire bridge on the electro- nic insert EC 61 Z. Where and how to install the NIVOTESTER FTC 420? The equipment is usually mounted in a switch cabinet on a symmetrical rail (top hat rail), in accordance with EN 50022-35x7. 5 or EN 50022-35x15. See fig.l. If the instruments are set flush with one another, the maximum ambient temperature in the switch cabinet during operation may not exceed 50°C (as measured 1 em above the instruments).

How to connect the NIVOTESTER FTC 420? Connecting the mains Note the mains voltage indicated on the front pane l or the sticker. Measure the mains at the site of instal l ation. Depending on the type, you can adjust the mains voltage in the instrument to local conditions. Changing the mains voltage Remove bo th terminal blocks. Open th e front panel by inserting a screwdriver in the slit above the front pane l and moving the handle upwards . Pull out the black insert from th e housing. Resolder the so ld er bridge on the circuit board according to fig. 7. Change the vo ltage indication on the instrument accord ing- ly . Reassemble the N IVOTESTER. Connecting the signal equipment Note that the relay function is dependent on the l eve l and t h e fail -safe mode . See fig. 8. If high-inductance equipment (e.g. contactors, e l ec tro- valves, etc.) is connected to the N IVOT ESTER, provision must be made for a spark absorber to protect the relay co n tact. Connecting the electronic insert You can use normal in stal la tion cable for the three -core cable from the NIVOTESTER FT C 420 to the electronic insert EC 61 Z (identification colour : orange). Maximum resistance 25 ~ per core . · If you anticipate cond ucti ve deposit formation o n the probe, insert a bridge between t erm inals 1 and 2 of th e e l ectronic insert EC 61 Z . Th e e l ectronic insert is u s u ally placed in the probe head. If ambient temperatures of more than 100°C are anticipated, th e ins ert may be placed in a separate h o u si n g. See Technical Information Sh eet No. 04. 82. 01. After the insert has been connected, the cover and cable d u cts of the probe head h ousing (or of the separate hou - sing) must be tightly closed. Selecting the fail-safe mode For the function of the relay and LED, see fig. 8. Select the fail-safe mode by means of a wire bridge at the upper ter- ~ minal block of the NI VOTESTER FTC 420: Bridge between t er minal s 12 and 13 : Maxi mum fail-safe mode -the relay is de-energized when the level rises above the switch point (the probe is co ver- ed) or when there is a mains failure . No bridge b e tw ee n terminals 12 and 13 : Minimum fail safe mode -the relay is de-energized when the leve l falls below t h e switch point (the probe is free) or when there is a ma i ns failure.

In the calibration method described below, the probe may not come into contact with the material. The calibration elements are situated behind the removable front panel. See fig. 9. Range seeking 1. Close the wire switch below (range I) Turn the knob from one stop to the next and back again. If the red LED lights up and goes off, see "Calibration". If not, see .point 2 . 2. Open the wire switch (range II). Turn the knob from one stop to the next and back again. If the red LED lights up and goes off, see "Calibrat ion". -- 1 f not, see point 3. 3. Close the wire switch above (range Ill). See "Calibration" for further instructions. ,Calibratio n at maximum fail-safe mode 1. Starting at the left stop, slowly turn the knob clock- wise until the red LED lights up. 2. Turn the knob a further half scale setting. Calibration at minimum fail-safe mode 1. Starting at the left stop, slowly turn the knob clock- wise until the red LED lights up. 2. Turn the knob a further half scale setting. How can you test whether the limit switch is operating p roperly? Fill the vessel (bunker or tank) until the sensor is covered by the material. If the NIVOTESTER does not switch on, carefully perform the calibration again. If the material tends to form deposits, check the switch point and, if necessary, make a slight correction after the equipment has been in operation for some time. There is another simple function test which can be per- formed without filling the vessel. With the sensor free, touch the main fastening screw of the electronic insert EC 61 Z with a screwdriver held by the insulated handle. The relay in the NIVOTESTER should then switch on. This is a function check for the electronic insert EC 61 z the connection cable, the NIVOTESTER FTC 420 and ' correct calibration. Coarse function test for the FTC 420 alone : You can simulate a risi n g level with a free probe by con- necting terminals 8 and 10 with each other . You can simu- late ? falling level with a covered probe by connecting termtnals 8 and 9 with each other.

Int::::oduction This gauae is a t...."lermcimeter '-'l t:n electric con tact com-:J:-is inc NEss' tem~erature indicator in which is incor-:Jorated a· J contact ~ystem including a microswitc~; a ca~ mounted on the ne~dle shaft moves a lever of the mic:-oswitch, and the switch is turned on and off at a setting temperature. 2. Main Handling Precautions This t~~perature switch consists of ar-indicator, an a~ored capillary tube and a ther.nobulb (therxosensor), •,.;hich ·::'"are connected in series. The interior of the svstem is ~filled with a liquid or gas. Therefore, when th~ capillary tube is broken or the thermobulb beco~es cracked, the internal liquid or gas will leak out and the temperature switch will not operate properly. Almost all troubles result from such leakage. 3. Transport 3-1 The indicating mechanism is very strocg against vibration. So, it will not become faulty while t=anspo:-ted by car or carried in packed condition unless G~ere is extremely rough handling. The contact mechanism sometimes operates reversely.because of vibration, but this presents no· problem since it can b€ corrected by a simple adjus~~ent at ~~e site. (Refer to the section on adjus~~ent methods.; 3-2 During· transport of the temperature s•,:i tch removed from the case, damage may be caused by carrying it with the capillart tube hanging down or conversely by holding the capillary tube wi~~ the indicator and ~~ermobulb hanging down. So, be sure to avoid such carr~ing methods. 4. Installation 4-1 Install the indicator in a selected location with small t~~perature changes, a good at....uosphere and small vibrations. When there are problems concerning te~perature changes, vibrations or the atmosphere, check tb.at the temperature switch is sufficiently applicable. 4-2 ·capillary tube 4-2-1 I£ ~~e caoillarv tube is twisted, c=ushed or subjected to cutting and ~elding during removal from the box o:- laying, the temperature sw~tch will lose its function. Be especially careful when· rewinding the capillary t'J.be in a coil form and when installing~ =he thermobulb.

Maintenance and Inspec~ion Fuji Electric Co.,Ltd. M680-851844-Pt 1/4 1· 1. GENERALL The object of the oil lifter is to lift the rotJr to from the oil film between the thrust bearing pad and runner by supplying pres=ure oil from injection hole in the center of the thrust bearing segment. By this a:tion friction at the time of starting the thrust bearing can be extremely reEuced or metal contract between the thrust bearing and runner during low speed running can be prevented. Since the oil supplied by the oil lifter is directly fed between the thrust bearings as explained above, utmost care must be paid at the time of assembling and disassembling never to let dust and other fcreign substance enter the piping or oil. Further, carefully carry out inspection of the accessories, and after grasping their characteristics put the equipment in operation. 2. USE This oil lifter is to be used in the following cases: 1) To make the oil film on the thrust bearing ~illen generator is put into operation. 2) To make the oil film on the thrust bearing ~'k.~en generator stop at the brake operation. 3) To make the oil film on the thrust bearing ~hen generator starts after a suspension for a long time. 4) To make the oil film on the thrust bearing Ln the maintenance work so that rotor can rotate by small force. 3.

MAINTENANCE AND INSPECTION 1) Check very often (once every month at leastj the following pressures. a) The maximum pressure when lifting the rctor. b) The pressure after lifting the rotor. When the above pressures deviate form the vaJues at the time of installation, it shall be confirmed by measuring a movemeiTt of slip ring or brake ring by dial indicator that the rotor is actually lLfted up. 2) Inspect very often (once every month at leasi) the oil pressure of the generator under running. In the event of pressure coming down under ~e same loading condition it is also considered as a reason that the check \3lve leaks. 3) Carry out the maintenance and inspection for the main components of high pressure oil pump set. 4) Cautions on Piping and oil Chargings a) Parts of thrust bearing high pressure oil piping shall be assembled after being sufficiently cleaned by passing cl3an oil through their interior. (When the internal piping has been dismaJtled). This clean oil shall .use the fresh one ~~ich has been cleaned through the filter. b) When charging oil to the bearing oil res3rvoir, the oil shall be returned entirely to the main tank after the oil reservoir is once filled with lubricating oil for cleaning its interi~r, and again the oil shall be charged up to the regular oil level. c) Carry out surely the work for the conneclion of bite type fittings of high pressure side piping according to the jcinting procedure of bite type pipe fitting.

Owg : M905-844399 (schematic diagram for P.H.Heating system) 1) The source air at 80"'-'120psi f101~s through the air filter and then is reduced and controlled in pressure to 20psi (1.4 kg/ell[ by the reducing valve (RDV) for the secondary devices. 2) The safety valve (RV) is provided to allow the air to escape to the atomosphere to protect the secondary devices in case the air pressure in the secondary pipes exceeds 23.5psi. 3) The 3-way solenoid valve (SOL) is normally clo~ed. When it is necessary to open the air louvers, SOL is energized by 125V DC power, thus supplying the air for the louver operators. To close the air louvers or In the event of a ~rouble in the generator such as a fire emargence shut down SOL is deenergized. Consequently, the air in the secondary piping is dumped through the exhaust port of SOL completely and all air louvers are closed within 30 seconds. 4) When the air is supplied to the louver operators by energizing SOL, all intake louvers open fully. @ 5) The discharge louvers can be individually conbolled in their opening from 0 to · (Po) · 100% automatically by operating the eL~:. ;;13l _position controllers~ v.'hich 3rvl5ps~;Air- is modulated by input signal 4 26uA re from remperature controller supplied by owner. Thus, the pov;er house heating air flow =.rom discharge louver can be controlled independently. The discharge louver also fully closed by the EXternal input signal which is energized in the event of fire or emargence shLt down of the generator. The position indicator (PI) are provided withE scale ranging from 0 to 100% corresponding to the louver opening. The opening of a discharge louver controlled b~ eleet±i:al position controller can be easily known by reading PI. 11950-851845 A 4126 6) The air at a constant pressure of 20psi (1.4kg,~m 2 ) is supplied by the reducing valve (RDV-2) to operate the positioners of the discharge damper operators. All the devices stated above under item 1)-6) are mounted on the louver control panel which is installed outside of the generator housing. "7) \I IJ A damper operator is mounted on the discharge a~r louvers installed locally. Its "--< stroke ranges from 0 to lOOX at a control air p:;:-essure of 2.8""'14psi C0.2"-'1.0kg :--\ /cm 2 ) to operate an air louver from full closed to full open. :"-1 - -..J -~ ~ :1950-851845 A 5126 4.

These actuators can also be used on other applications that require a large amount of pos i tio n i ng power from a single actuator, such as large damper applications, provided that the damper is designed to withstand the high torque capabilities of the actuator. 'rhe 0-3240 Series Actuators are furnished with an 8 to 13 PSIG (56 to 91 kPa) spring range and are available in two mountin g configurat ions : swivel-mounted and pedestal (sing l e or duplex) floor- mounted . F loor-mounted models are furnished with a factory installed and cal i brated D-9502 Posit ioner; swivel-mounted models a r e available with or without the positioner. The posit i oner may also be ordered separately at a later date for additional pos iti oning power should the application require it; refer to the Speci fications Tab l e for ordering information. For actuators with a positioner. if it is necessary to extend the piston rod to make the linkage attachment, loosen the posit i oner spring arm before extendi ng the rod and make sure the spring is just taut before retightening it. Mounting Application requirements dictate the type of mounting necessary; refer to the dimension drawings for mounting details . Tables 1 and 2 list the actuator force values e 24-4659 -9 Rev.

The excitation system consists of excitation transformer connected to 13.BkV main circuit, thyristor units cooled by forced air, field circuit breaker and automatic voltage regulator with electronic type voltage setter. The equipment regulates the voltage of the generator by automatically controlling the field excitation current. This manual shows the principal operation method for the excitation voltage regulating system. Regarding the detail operation of automatic voltage regulator, please refer to separate manual No. TN501782. (Note) Reference sheet numbers show the sheet number in schematic diagram No. W410353. 2. Field circuit breaker (41) and deenergizing contractor (93R) ...•. Ref. SHll, 13 Field CB (41) and deenergizing contractor (93R) perform primarily the opposite operation. Therfore, when turn the field circuit ON, turn OFF 93R first, then turn ON 41. Also, when turn the field circuit OFF, turn ON 93R first, then turn OFF 41. Field circuit breaker closes automatically when following condition are met. ll21S - 2 - (1) Master relay 4 is energized (APA supply) (2) Turbine speed 13 reaches synchronous speed (APA supply) (3) Lock out relay 86E is reset (4) Setting value is minimum position in 90AMIX or 90MLX Field circuit breaker opens automatically after generator circuit breaker is opened when master relay 4 is deenergized or lock out relay 86E is energized. This circuit breaker's contacts are used for red and green lamp indication at AVR panel. 3. Initial Excitation and Voltage Regulator (Ref. SH12, 13) When the field circuit breaker 41 is closed, initial excitation starts by energizing initial excitation contactor 31. Initial excitation continues until automatic voltage regulator operates, (by auxiliary relay 90XA which is energized by voltage build up signal 53GX) or until timer 31T ti~ed-up which means initial excitation failure. 4. Regulator Volatge Adjustment ("AUTO" Position) (Ref. SH18) The operating voltage of the generator terminal during automatic regulation is selected by controlling the setting value. The setting value of the terminal voltage can be adjusted as follows. a. When field circuit breaker 41 opened, the setting value of terminal voltage is remain the preset value. 1121S -3 - \ / b. When the local-remote change over switch 43-41 located in AVR panel is selected "local" position, the setting value of terminal voltage can be adjusted by the control switch 90A/CS located in AVR panel. c. When 43-41 is selected to "remote" position, the setting value of terminal voltage can be adjusted by main switchboard's. 5. Regulator Field Current Adjustment ("MANUAL" Position) (Ref. SH19) The adjusted field current during manual regulation is done by controlling the setting value. The setting value of the field current can be adjusted as follows. a. When field circuit breaker 41 opened, the setting value of field current returns at the lowest value. b. When the local-remote change over switch 43-41 located in AVR panel is selected local position, the setting value of field current can be adjusted by control switch 90M/CS located in AVR panel. c. When 43-41 is selected remote position, the setting value of field current can be adjusted from main switchboard. 1121S - 4 - 8. Excitation Metering (Ref. SH13, 15) The following indicators are located at AVR panel. a. Visual supervision of exciter field voltage, VM is of DC voltmeter (scale 0-600 volts) connected across the excitor field leads. b. Visual supervision of exciter field current, AM is of DC millivoltmeter fed from 100 millivolt at 1,400 ampere DC shunt connected in the positive field lead. (scale-0-1,400) amperes. c. Balance meter, B, indicating the difference signal between firing angle orders of manual regulation part and automatic regulation part. d. For metering excitation field current at the main switchboard, isolating converter (0-100 millivolt to DC 4-20mA) is installed. e. For metering field voltage at the main switchboard, 0-600V/4-20mA signal of field voltage is provided. f. For metering auto-manual balancing at the main switchboard, the signal terminals are provided. ll21S - 6 - 9. Field Protection (Ref. SH13) a. Generators field ground protection (64E) 1121S The generator field circuit is isolated from ground, therefore a first ground fault in the field winding does not cause major damage nor disturb the machine. However, on the occurrence of a second simultaneous ground, a considerable portion of the complete field winding will be short-circuited and the resulting unbalnce magnetic fluxes will produce unblanced forces between the rotor and stator. These forces causes serious vibrations, shaft distortion, or rotor heating may take place. To detect a field ground fault, a field ground relay, device 64E, has been installed. - 7 - / .· CC.

INTRODUCTION This instruction manual deals with the outline of the automatic voltage regulator using Fuji's newly developed analog control element ser'ies "Transidyn D" (brand name) which is designed to be used with AC generators. The "Transidyn D" series is a standard printed circuit board mainly consisting of high reliability IC s, being widely used ·· in various plants such as power plant, steel-making plant, etc. with high reputation. The automatic voltage regulator (AVR) features quick response and minimum control deviation; it is composed of a main control unit comprising a printed circuit board "Transidyn D" and an exciting current control unit composed of a thyristor circuit. The following describes the operating principle of the AVR. TN501782 \ 3 2. OUTLINE OF EXCITATION CONTROL SYSTEM A block diagram of the thyristor direct exciting system is shown in Fig. 1.

(2) The setting voltage of generate~ is constituted of the voltage setter (90R) and the starting setter.

(3) The output from the voltage dete~tor is compared with the signal from the voltage setter (90R). (4) After comparing, the deviation is computed in the PI controller. The PI controller provides an optimum gain for the control loop in P (proportional band) and eliminates the offset error by I (integration). Thus it makes a quick response and free from ~teady state deviation. The thyristor firing angle is controlled with the PI controller output by the.firing angle controller. As the thyristor firing angle (a) is controlled, the field voltage (current) is also controlled. In case of the. thyristor full-wave bridge circuit, the field voltage is: Ef = 1.35 EA cos a Ef = Field voltage EA = Seco~da~y voltage of exciting transformer a = Firing. angle In case of the hybrid bridge circuit; Ef = 1.35 EA 1 +"cos a 2 Tl'f501 782 5 I 3. FEATURES OF AUTOMATIC VOLTAGE REGULATOR This .. device is a part of Fuji • s Transidyn control system using silicon transistors and linear IC's, and has the following features: (1) The dimensional units are standardized and functional elements are arranged in a draw-out type unit of specific dimensions. (2) For the convenience of maintenance and adjustments, the draw-out type unit is provided with the check terminals (Jl."' ~20) on the front: of" the unit to check the setter (RSOO in the instruction manual), the operation and the voltage wave form. (3) In the· analog circuit of the functional unit, high performance linear IC is used and in the digital circuit, 16w nois~ and high r~liability digital IC is ~sed. (4) The automatic voltage regulator is easy to maintain·and highly reliable, since its mai,n control part·, manual control and automatic_fo~lowing control part, restriction part for the leading and lagging reactive power, and power system stabilizing part are on individual pr~n~ed boards,_and its structure is simple. (5) The automatic voltage regulator is free from trouble caused by poor contact, etc., since the voltage setter (90R) uses an electronic counter and D/A converter which are provided with no sliding parts. (6) Since variation in the firing angle of each thyristor caused by frequency fluctuation is automatically compen- sated for, a permanent-magnet generator (PMG) or tachometer generator (TG) need not be used. (7) To facilitate maintenance and adjustment, controls (indi- cated as RS in this manual) and test jacks for checking operating voltages and waveforms (indicated as J in this manual) are mounted on the surface of unit as shown in Fig. 2.

(b) Start Setter (Unit integrator) Start setter is an induction device for establishing voltage without over shoot up to the setting value of 90R-after the initial excitation. This start setter is provided only to AVR for thyristor excitation. As shown .in Fig. 5, the output Vls of start setter' is 0 '7. at the beginning when the "use" contact is Put ON, rises gradually as the time elapses and stops at . . the value equivalent to the 50 % voltage. !'fhis time can be set as about 5 seconds. On the other hand, the voltage setting range of voltage setter (90R) is 0-30 '7.. Therefore, when the voltage setter starts at the lowerst limit value of 90R, the output vol~age of the amplifier 5l(Jl4) is the voltage setting value. In other words, AVR is,put in the status of use after the 30 '7. voltage has been established by the initial excitation. and the voltage rises up to 80 '7. in 5 . . seconds together with the rise of Vls. If this rise time i~ longer than that of the generator T'do, there will be no over shoot at the time of start. After the start has been completed, it is possible to set a voltage of 80 ~ 110% (80 + (0~30%)) by operating 90R. (2) Position Detector When the voltage at Jl4 (voltage setting value) is increase above the voltage set by RAll, the output of the amplifier 40 becomes negative, and the output of fransistor array 46" is turned on ·and there by . external relay (90RLS1) is operated. The other parallel circuit (90RLS2) operates in the same way. TN501782 jt71 c·.

Thus, this output is smoothed with a filter provided at the input of this unit. Since the output from the voltage detector was rectified in three-phase full-wave mode, it is smoothed through the filter provided as mentioned above. The deviation from each input is computed by the amplifier 26 with the most suitable gain for the control loop selected by RS 5. The integral time constant can be . changed by RS6. The amplifier 26 is also provided ~ith _ limiter function and zero-hold function. The positive side limit voltage can be set by RA43, and the negative side ·one can be set by RA42. When the AVR is not used and command of Zero.Hold is at "L"(low), the output voltage is fixed at 0 V by the zero hold function. c.

The adjustable range is within 1 to 20 times. RS6 I Time Constant of PI Regulator The I ·time constant is set to the most suitable value for the contr9l system as in RSS.

(V) [ TN501 782 )2 5 I Explanations of the operation When the voltage of A (+) -C (-) is applied between anode (A) and cathode (C) as shown in .Fig. 10, thyristor is energized if· (+) voltage is applied on gate and (-) voltage is applied on cathode. It is, therefore, necessary to ke~p synchronous relation at all times between main circuit voltage and gate pulse in order to· operate thyristor continuously. The AC voltage, supplied to FAR from the power source with the same phase as main circuit in order to determine generating position of gate pulse, is called "synchronizing signal". In case thyristor converter is of 3-phase pure bridge, gate pulses w~th phases varying at every 60° are required. Accordingly, 6 phases are provided for synchronizing signal, and the circuit •. whic? generates pulses according to this, ~s composed of 6 circuits. The generated pulse· is shifted to lead or lag in relation to control signal, always keeping 60° interval. Anode (A) I+.

(a). Saw-tooth \<lave Generator Diode D7 9 The following description is given on the U phase. During the positive period of sync. signal, D79 is turned off~ and the amplifier 33 integrates the voltage at Jl, while during the n·egative .Period, D79 is turned on, and therefore the output of the amplifier 33 becomes ov. Thus, the amplifier 33 delivers the saw-tooth waveform output signal. (b) Frequency Correction Circuit This regulator ope.rates with the relation of thyristor firing angle 0 "' 180°/0 "' -10 V. Since the integral. time constant of the amplifier is constant, the integral final.value (UI) is below 10 V when the sync. signal frequency increases; it is above 10 V when the sync.signal frequency decreases. Since the total val~e of all 6-phase saw~tooth wave . •. change in proportion to the frequency, 6-p?ase saw- tooth waves are.totalized by the amplifier 28, and the result is compared with the value set by. the reference frequency setter RA18, and closed loop operation is performed so that the voltage at Jl is increased when the frequency is higher, and it is decreased when the T~50l.782 \3s\ (c) (} 7 1 frequency is lower. Thus, the characteristics of the saw-tooth wave genera- tor are controlled so.that the relation of 0 ~ 180°/. 0 ~ 10 V is always kept. Pulse Generator The above-mentioned saw-tooth wave is compared with the output of the matching amplifier by analog comparator 36. When t~e resultant output is minus, transistor Tl6 is turned on and thereby a gate pulse is set out. Since this circuit.contains an OR gate to which a ~0° lag signal is also applied, the gate pulse becomes a double pulse as shown below. - v pno•• poll .. 1----..u.--.LL...------"-__.II.-- x phaM $1UI•• ,_ ____ .......__.... _____ __.~~.__.._ TN501782 13 7 I c.

Explanations of the operation When the volta~e of A (+) -C (-) is applied between anode (A) and cathode (C) as.shown in Fig. 31, thyristor is energiz- ed if (+) voltage is applied on gate and (-) voltage is appli- ed on cathode. It is, therefore, necessary to keep synchrono- us relation at all times between main circuit voltage and·· gate pulse in order to operate thyristor continuously. AC voltage while is supplied "to FAR from the power source with the same phase as main circui.t in order to determine generat~ng position of gate pulse, is called "s-Ynchronizing signal". In case thyristor converter is of 3-phases pure bridge, gate pulses with phases·varying at every 60° are required. Accordingly, 6 phases are provided for synchronizing signal, and the ·circuit, which generates pulses according to this,· is composed of 6 circuits. The generated pulse is~shifted to , lead or lag :in relation to control signal,. always kee.ping 60° interval.

Since the integral time constant of the amplifier is constant, the · integral. ·final value (UI) is below 10 V wher the sync signal frequency. increases, it is above 10 V when the . sync signal frequency decreases. Since the total value of all 6-phase saw-tooth wave change in proportion to the frequency, 6-phase saw- tooth waves ar~ totalized by the amplifier 23, and the result is compared with the value set by the reference frequency setter RAll, and closed loop operation is performed so that the voltage at JlO is increased when the frequency is higher, and it is decreased when the frequency is lower. TN501782 17 1)_ Thus, the characteristics of the saw-tooth wave genera-- tor are controlled so that the relation of 0 ~ 180°/ · 0 ~ 10 V is always kept. (c) Pulse Generator The above-mentioned saw-tooth wave is compared with the output of the matching amplifier by analog compara- tor 45. When the resultant output is minus, transistor T1o is turned on and thereby a gate pulse is set out. since this circuit contains an OR gate to which a 60° lag·signal is also applied, the gate pulse becomes a . . double pulse as show~ below. - V ph<ln P<~lu t-----....._-"-------LI--"--- X pllcM p..ls• t------....__..... _____ _..___..__ DC oulp~l vclfog• · c.

Since R'D is negative when ~Tex has appeared at the ·3rd and 4t~ guadrants, the overall damping torgue (TD + T'0) becomes small and the damping force becomes . . insufficient, attenuation of oscillations becomes poor and, in extreme cases, the overall damping torque becomes negative (Fig. 48). torque Fig. 48 Negative damping TNq01782 19 9 I This is for the case of Fig.44(c) ·previously given and . . becomes divergent oscillation. This phenomena occurs when KS<O in the block diagram of Fig. 45 .. When the external reactance (Xe) is large as a system start, the load may be heavy or the generator may be in a greater leading operation. In such cases, if the AVR delay is made small by using a · thyristor and high gain, high-speed response excitation is applied, T'D will gradually becomes negative and stability will suffer. 4. Compensation-by PSS To improve stability without loosing the effect of high speed response, even when the overall torque causes weak damping or negative damping as previously described, the damping torque should be increased by adding a compensation signal to the AVR. This is the so called PSS. Generally, the power deviation (6P), frequency deviation (6f); ?peed deviation (6w), etc. a~e used as the compensation signal~ When deciding the PSS function, first ~he phase of 6Tex of Fig.46 is.studied from the angular frequency (w). Although w differs with the· system composition, generator constants, operating state, control system constants, etc., its frequency oscillation under actual operating conditions ranges from about 0. 5Hz to 2Hz. (Expected range 0.1 to 2Hz) Taking the lo.op delay· at G(s) l:.Tex of F~g.45 into considera-. tion, the PSS function is selected so that the desired overall torque is ·obtained.

Introduction 11 ?--lOLTRA" is our pet name for an epoxymold dry type transformer which we have succeeded in developing for the first time in Japan and introduced on the market. "MOLTRA" has a winding which is molded by epoxy resin. Its general construction is illustrated in Fig. 1. The conductive part of the winding is entirely coated by epoxy resin . . Rating plate lug . Earthing terminal Secondary terrn~al (Low voltage) Fig. 1. Construction of mold transformer (An example of three-phase transformer) Fuji Electric Co.,Ltd. INT-TR 757010-E 1/7 2. "MOLTRA" has various features: o Safety against fire since it does not use insulating oil and epoxy resin has a self-extinguishing nature o Hardly subject to be influenced by dust and moisture in the atmosphere when in operation since the conductive part of the winding·is all molded by resin o Small and lightweight o Low noise and low loss 1 This instruction manual describes the maintenance and checking method for "MOLTRA" classified into daily and periodic checks as follows: Precautions Prior to Operation It often occurs that during the period after "MOLTRA" is shipped from our factory, installed at the site and put into operation, · outside dust such as cement powder may penetrate into the device when places for installation are under construction. Therefore, when shipped from our company, do not remove the vinyl covering which is fitted to the device until full oper~tion is started, for protecting "MOLTRA". Before commencing the operation, carefully clean every part of the device, visually check its external appearance and, by measuring the insulation resistance, compare the measurement with the test data from our company. Thereafter, start the operation. 3. Daily Check In the daily check of "MOLTRA", as in an oil-immersed transformer and H-class dry type transformer, perform the following: o Record the voltage, current and frequency during the operation. o Check the noise, odor, operating condition of the cooling device and temperature. INT-TR 757010-E 2/7 1 Perform the checks of the following items which are particular to "MOLTRA" taking care to safety. (a) Check visually the winding, core and connection lead for any damage, discoloration and the degree of dust deposits. (b) Check the winding supporting structure for any damage, degree of contamination and mark of electric discharge. (c) Check the contamination in the air filter, and, if found to be extremely dirty, replace or clean it. (' (d) Under the operating condition where starting and stopping are repeated, take care that the humidity should be reduced as little as possible. 4. Periodic Check The standard periodic check of "MOLTRA" is to be performed on a six-month or yearly basis. It is desirable that the interval of checking should be determined depending on the operating conditions after 2-3 months since the operation is commenced,- and on the ambient conditions. 4-1 Checking Dust Accumulating Condition Check the dust accumulating condition at the core, winding and lead wire. If the dust accumulation is large, blow it off with compressed air, or clean the dust off with a vacuum cleaner. INT-TR 757010-E 3/7 1 Wipe the accessible part~ other than the winding with a dry cloth. Never use cleaning agents such as benzine. The inside of the core and winding cannot be fully cleaned without compressed air. The compressed air to be used must be one with little moisture and its pressure should be appro- ximately 1.5-3.5kg/cm 2 . The blowing direction of the air must be, in principle, opposite to the flow direction of the cooling air while "MOLTRA" is operating. 4-2 Checking the Condition of Corrosion Inspect the core, clamping fittings and outlet of the lead wire for corrosion (rust). If corrosion is detected throughout the transformer, most of the time it can be attributed to the atmospheric air used for the cooling air; therefore, filter the air by identifying its components.· Or take a countermeasure to prevent ~he incoming of the humid or contaminated air into "MOLTRA", or apply a trans- former with anti-corrosion paint. In the case where a protective casing is fitted on "MOLTRA", when not in operation, water dew which has changed from vapor put inside the protective casing and partial corrosions take place, so get rid of the rust and repair with paint. If these countermeasures are difficult to perform, please consult us on the matter. 4-3 Judgment of Insulation Deterioration Check the resin layer of the winding and the winding support insulation spacer of "MOLTRA" for color change or crevices. If considerable crevices are seriously formed, please consult us. Next, measure the insulation resistance. The insulation resistance is to be measured with a megger. INT-TR 757010-E 4/7 1 In each measurements, it is desirable that the ambient condi- tions such as temperature and humidity should be about the same. Acceptibility of the measurement results are to be decided according to Table 1 below. If the measurement results are below the values shown in the table, the cause is mostly ascribable to contamination of the windings, lead parts or the winding support space~s. Clean and remove .the dust from these parts. If necessary, perform hot air drying processing. Table. 1. Lower limit of insulation resistance (at 25°C) Voltage (kV) Below 3kV 6kV lOkV 20kV 30kV lkV '· Insulation 5 20 20 30 so 75 resistance (MQ) . If the nominal voltage of the transformer is not in Table_l, the measurement results are to be decided according to the value of the upper voltage. 4-4 Checking Conductive Parts Check the conductive parts such as the lead wire connection part and tap changer for any loosening. overheating and corrosion. Overheating is caused by an insufficient contacting area or sectional area, loose contact of contacting faces and rust. Investigate the cause carefully and take appropriate m~asures. 4-5 Checking the Cooling Dev~ce When the unit capacity of "MOLTRA" is increased and it is operated as an air-cooled type by insta~ling a coo~jng fan, INT-TR 757010-E 5/7 " 4-6 1 check each part of the fan and supply lubrication oil. If the cooling device has a thermal relay attached, make sure that the relay operates normally. When a thermistor sensor and dial thermometer are provided, make sure that these protective meters are correctly mounted and function normally. Check the air filter for contamination and, if it is excessive, replace or clean the filter. If there is abnormality in any part of the filter, repair replace it with a new one. Checking Loosening of Parts Check if there is loosening in any of the parts. If there is, torque it further. For the winding support spacer, a flexible spacer is used. Therefore, no loosening will occur and further tightening will hardly be necessary. Check the tightening parts as in the retaining fitting for loosening and torque it further if necessary. or 4-7 Checking for Crevice of Resin Molding 4-8 Check if there is any crevice in the resin molding of "MOLTRA 11 • Being rigid enough, there is no need to worry about the occurrence of a crevice during operation. However, if the resin molding has been damaged by an abnormal external force, please consult us on the matter.

INT-TR 757010-E 6/7 1 5. Precaution 5-l Never touch the surface of the molded winding when the trans- former is energized. 5-2 When wiring the transformer to the network, care must be taken to keep the conductive matter such as bolts, washers, wire, etc. from falling to the transformer. Do not step on any parts of the mold transformer to prevent them from damage. INT-TR 757010-E 7/7 }; ! ·.

Structure The dial type thermometer, as shown in Fig 1, is of the vapor tension type and is composed of three components of heai sensitive element, indicator and intermediate flexible tube ~onnecting above two components, which are assembled into·one unit.· The transformer body is provided with the support for the heat sensitive element. The indicator is on the other hand provided with the fixed p~inter for alarm and extra pointer for indicating the maximum temperature in addition to the ordinary temperature indication pointer. Both the fixed pointer for alarm and temperature indication pointer are provided with the electrical contacts and when the temperature pointer reaches the temperature specified by the fixed temperature pointer, the electrical circuit turns ON. The terminals of them are provided at the lower side of the indi- cator as the alarm terminal which is being connected to the alarm circuit. The maximum temperature point~r indicates the maximum temperature of a day or a certain period and it shall be set near the pointer by the adjusting knob at the front of indicator. The fixed pointer for·alarm can easily be set to the desired tem- perature if the front glass cover is removed. Usually the fixed pointer shall be set at the following tempe- rature. Setting temperature = t~mperature rise value 9btained by tempe- rature test + ambient temperature of 40°C (This can be adjusted properly according to the operating cond i ton)· .

Maintenance 14 Particular maintenance is not required but it is recommended to perform following checks at least once a year respectively. a) Check for indication value: Check the indication value by comparing it with that of other indicator. If indication values are largely different, the indi- cator shall be removed and be subjected to the error measure- ment ~ndependently. b) Check for alarm circuit: Make sure· that the signal appears at the terminal when the alarm contacts closed. Measure the insulation resistance between terminals and case with a 500Y or lOOOV megger. The measured value is approx- imately 1 M.ohm and above. .· INT-TR 750445-E . i ~ ± FUJI General-Use RF 240Type Disconnecting Switch RF 240 ~ [5f .i! ~-. ~ ~ Type RF240CZ/J.v '3o/6~o (F-F) f<F24ocrj3-J3oj,z:J-:J (,t:-p.). _RF24CJ:cr.J?-./Joj 2ooo CF-F) Handling Instructions . 11 ± R F 2 4 0 ~ l!fi !$ H ~ to ~ ~' 1:.

After inserting a fuse link in the damps, firmly tighten the screws. When tightening the clamp at the front side, ·align the movable contact with the stationary contact when the fuse link is closed, then tighten the screws. (2) After installing the fuse link, confirm that engagema •. of the pawl at the ·c • part will not permit the dis· coMeeting part to open even when the · • B • part is pulled in the direction of arrow P. Should it open when pulling the ·a· part, move the movable contact in the direction of arrow Q after loosening the screws on the damp. (3) Further, ascertain that the disconnecting part can be freely opened when the ·A· part is pulled in the direc· tion of the arrow P. • Other precautions (1) Firmly tighten the contact parts and terminals; other- wise, an increase in contact resistance may cause overheating resulting in trouble. {2) When installing a fuse link in the vertical position. exercise care that the interruption indicator is position- ed at the lower side, which may offer ease in reco nizing interruption. ~ ~~~~t&-~lJ~?~M&~~~&n&q~L~ se ~ f'Pltl-r'-t 'br, 7 a ~ 1-t!4c: ;;;r.EtJrtc h., "C ~. • .t~ ~c:u.~:;: L r.c~·un~~c:r.t7e~=u:,~ < t!& ~·.

In case the front side is applied with voltage, however; utmost care should be given to the operation to avoid an electric shock. (4} When operating the fuse link (especially when opening the circuit), do it slowly to avoid shock. (Do not detach the operating rod from the clamp until pole opening is completed.) 2. MAINTENANCE & INSPECTION (1) Inspect the porcelain supports, and the fuse link cera· mic tubes for damage, flaws,. contamination due to dust, and cont.amin~tion caused by salt deposits. When damage or flaws are detected. immediately replace the defective parts with substitutes. Since extreme contamination involves the risk of tlashover, thoroughly clean the surfaces of the porcelain supports and ceramic tubes. · (2) The fuse link is provided with an interruption indica· tor having a construction in which the indicator rod is popped out by spring force should the electric current be interrupted. During an inspection, check whether or not interruption occurs. (3) If the contact parts and terminals are not fully tighten· ed, an increase in· contact resistance may cause heating up, resulting in trouble. Check on possible loose bolts or incomplete contacts. (4} It is recommended that three fuses of three-phase circuit or two of single-phase should be replaced as a whole· set after Power Fuse works. Because there is a possibility that the fuse element left is aged owing to the fault current ruMing through it.

The white disk pushes-the switch lever and the switch turns to ON, sending a blow- out signal to the outside. As the switch lever is ejected, the state of the switch can be checked visually. ' Since the switch is reset when it is removed from the blown fuse, it can be used repeatedly by replac- ing the fuse element (with adaptor) alon~. · Nhen the fuse blows, replace the fuse element with a new one and check the thyristor and its circuit for any signs of defects. The details of trouble should be reported to us. o Fuse replacement As shown in Fig. 4(a), the fuse is a set of two elements connected by a bar.

(8) Nipe the surroundings of the removed thyristor with a cloth. (9) Insert the thyristor replacement jigs from the upper and lower sides of the stack to remove the thyristor by flipping the heat sink between both sides of the thyristor. [Mounting Procedure] (10) Twist the thyristor leads like.other thyristors. If required, clean the thyristor with a cloth moistened with alcohol. Then, apply a coat of thermal compound HSC-100 to the thyristor el~ctrode using a brush. (11) Insert the thyristor from the upper side of the stack. First insert the leads through the two guide pins. The polarity of.the thyristor is the same as before and it can be checked by the marks on top of the front panel or the direction of the thyristors in the stack. When inserting, hold the thyristor by fingers without pulling the leads. The cleaning in item (8) should be made carefully, otherwise the electrode becomes dirty with dust. Press in the thyristor toward the lower side of the II NR-M~_30203-E .. ~ I I ) stack until the two guide pins contact the case. The thyristor is now inserted. (12) Remove the stopper of the thyristor replacement jigs following item (9) in reverse order and slowly lower the heat sink on the thyristor. (13) Check that the pressure gauge is open as shown in Fig. 5, and that the upper end of the gauge is aligned with the lower end of the plate spring. If not aligned, correct it and tighten the nuts evenly and lightly until the plate spring becomes level. (14) Check that the thyristor is centered; that is, the two guide pins should be in contact with the casP.. If required, make adjustment. (15) Using a long size spanner, tighten the nuts evenly and slowly until the scale of the gauge is aligned with the lower end of the plate spring as shown in Fig. 5. (16) Check the characteristics of the thyristor using a curve tracer. This should be ~ade after removing the connection of the protective circuit at the lower portion of the heat sink (one side only, for example, the cathode side). (17) Mount the protective circuit in the reverse order of removal. Tighten the fuse and connect the leads of the thyristor securely. jtNR-MK 30203-E 14 [No tel Before replacing thyristors, record the serial No. and classification symbols (stamped on cathode) of the new thyristors so that the thyristors and corresponding stacks can be identified.

(1) Observation of the waveform of voltag~ applied to the thyristor in use (2) Observation of pulses between cathode and gate. (3) Existence of short between anode and cathode (4) Gate continulty short or open circuit between cathode and gate The items (1) and (2) can be checked for correct waveforms by using a synchroscope. The items (3) and (4) can be checked with a tester while the panel is not in operation. To measure leak current of the thyristor, the protective ; circuit should be disconnected from the heat sink. The check terminals are located at the lower portion of the front panel. * Check terminal symbols for pure bridge stack Thyristor Anode Cathode Gate THl R A R K R G' TH2 s A s K s G TH3 T A T K T G * Check terminal symbols for anti-parallel stack I NR-MK30203-E '117\ * Check terminal symbols for anti-parallel stack Thyristor Anode Cathode Gate TBl 11\ lK lG TH2 lK 2K 2G TH3 3A 3K 3G TH4 3K 4K 4G By using a tester, thyristors can be checked in a simple manner. In the following, the plus <+> and minus (-) signs represent the polarity of the battery in.the tester. (1) Check of anode-to-cathode circuit (presence of short- circuit) \'lhen the anode is connected to (+) and the cathode to (-) or connected in reverse, check that the resistance between the anode and cathode is lK ohms or larger. rf·it is less than lK ohms, the anode may be shorted to·the cathode. Since a protective circuit is pro- vided with a capacitor, the resistance of less than lk ohms is sometimes indicated. For accurated measureraent, it is recommended to use i curve tracer as outlined below. (2) Gate-to-cathode circuit (presence of GK ~hort or open circuit) The resistance between the gate and the cathode is non- IN R-MK30203 -E jji] linear, so it varies more or less depending on the voltage of the tester. Also, the reverse voltag~· between the gate and cathode of thyristor is 10 V and care should be taken not not to apply ov~rvoltage. The tester should be set to the lowest ohm range; a tester of 1.5 V type should preferably be used for the measurement. Short-Open- Condition Normal circuit circuit Gate ( +) , Cathode ( -) 1-son (approx) on (., Gate (-) , Cathode ( +) 3-son (approx) on 100 (approx) To measure the dielectric strength or leak current of thyristor, draw out the stack from the panel and ~is­ connect th~ protective circuit at the lower portion of the heat sink at the cathode side (3 pure bridges and 2 reverse oarallels) . The leads disconnected should be insulated by wrapping with tape to prevent them from touching the heat sink and bars. After the above has been completed, ma.ke measurement using a curve tracer. The standard value is less than 60mA at 2500V. I NR-MK 30203-E ~\19] o Cleaning of Stack (1) Clean the stack by blowing dry air. Make certain to remove the deposits of dirt and dust from the parts, particularly the connectors, printed circuit boards, . heat sink, terminal screws, etc. By blowing the air, dry dust can be easily removed, but oily dust will remain sticking. Oily dust can be removed by using a dry cloth. When cleaning, care should be taken not to damage the printed circuit boards, electric parts and lead wires. (2) After the cleaning, check that the lead wires are free from breaks or printed circuit boards and parts are free from deformation .. Then, install the ·Stack correct- ly in the thyristor cubicle and tighten the mai~ circuit connecting bolts. (3} After the stack has been installed, check the pulse waveform at the .. line between the gate and cathode of the pulse transmission circuit of each stack removed. to insure that it is normal before starting test operation or normal operation. The-stack should be cleaned at least once every 6 months.

Connecting Procedures (1) Securely bolt the main circuit connecting bar stock to the terminal part projecting upward and downward (T and C5 in Fig. 2). Since each phase is branched off in 4o'ooA Typ~ and ~OOOA Type.· Cir- cuit Breakers, connect the~ ~ery carefully. When the connecting part of the connecting bar stock is bare, unplated copper piece, polish its contact surface with a copper wire brush and coat it with a thin film of grease before con- necting it. When connecting the connecting bar stock, be careful not to exert any unreasonable mechanical force on it. Also take it into account that an electromagnetic force will be produced when a heavy short-circuit current flows through 'it •. Incidentally, take it ~into account when connecting. the ACB (Air ~ircuit Br~aker) to the ~us bar that it has to be drawn out forward (in the direction of the operating machine) when inspecting·tt.

OUTLINE OF CONSTRUCTION (Fig. 9 and 10) (1) As shown in Figs. 9 and 10, the side wall (A) a·nd partition wall (B), made of insulating material, are fastened with ·a bolt (C), .the space between the walls houses conductive units whos~_number co~responds to that of poles, and the actuating mechanism is arranged outside the side walls. ·The front is equipped with the front panel (D) which supports the side walls and carries the operating mechanism (E). (2} Since the contact surfaces of the f\xed and moving contact pieces are faced with silver plates, their plates, their use will not be affected by their function to interrupt rigorous heavy current. Incidentally, the main motor-operated part is composed of fixed and moving contact pieces (~GH), arc contact piece (K.L.), blow out coil (S), and terminal (T). (J) The arc contact pieces, made of a special alloy, are constructed so that when overcurrent flows, the contact pressure between the fixed and moving arc contact pieces (K.L.) automatically increases. (4) The arc is subjected to magnetic blow-out action within the arc-control chamber (M) and is blown backward. The shape of the arc-control chamber (M) is rectangular for all applicable AC voltages and for applicable DC voltages not exceeding 250V. V-shaped arc-control chambers are employed for DC voltages exceeding the above- mentioned limit. The arc-control plate (N) in the arc- control chamber, by finely splitting an arc and exerting de-ionizing action, rapidly extinguishes an arc, breaking the circuit. (5) The actuating mechanism i~ a free-trip type, and its ON/OFF position is constructed to be functionally indicated by the indicator plate (0) aboye the front ;anel (D). -23- (6) The terminal board for the auxiliary circuit (P) is mounted underneath the middle part of the front?panel (D) and can be readily connected to the auxiliary circuit. (7) In addition to direct manual operation, and the electrical operation the ACB can be remote~topera'tea by the operating lever or a smal1ll$Ca1l!ed motor. A circuit where a short-circuit current exceeding 15KA is anticipated is particularly.suitable for int~rruption by an operating device ·which makes use of a small~scaled motor. (8) The release is either 'an instantaneous over-current release type (Q} or an inverse-time-limit overcurrent type (R) type; in the case of AC application, either of them for each pole can be mounted on request. Also, an under-voltage release or a voltage release (V) can be mounted on request. (9) The auxiliary switchgear (U) can be employed for the circuit for a signal device, interlock device, and so on. (10) Since the terminal for the main circuit projects above and below the ACB, it can be readily connected. (11) The barrier {W), not.furnished for an ACB handling AC not exceeding 250V, is furnished for handling DC or AC which exceeds 250V.

The mechanisms on the right and.left are connected to each other via the center me9hanism. 1. Action of ACB by the Operating Device at Mak1ng Time (Fig. 11) By turning the operating device in the direction of making, the drive shaft (I1J) begins to rotate clockwise. This movement is transmitted--through .the drive crank (11) and coupling lever (12)--to the free trip lever (1,5), which begins to rotate clockwise along the circumference bf ~he main interrupting shaft (115). At this time the hook section at the lower end of the free trip lever (1,5) catches the roller within the rooller lever (17), and then ,r··~~"Jlt, makes it rotate together in the clockwise direction. The r~lease lever (16), due to rotation of the roller lever (17), begins to rotate clockwise along with the main interrupting shaft (r1.5) while elongating the interrupting spring, when the release lever (IB) has its top pressed by the roller of the roller lever and is shifted until its right-hand end hits the release shaft (114). Thus it becomes unable to make any further movement, and the roller lever is rotated clockwise while it presses the release lever downward and slides along its top. -27- Onnthecrigl1t-hand side (Fig. 12), the hitting lever--'t?Y rotation of the main interrupting shaft (I15)--rotates counterclockwise while elongating the interrupting spring (I12). By -action of the rotating main interrupting shaft (I15)~ the arc contact pieces and the main contact piece are made one (refer to ill, Contacting Part). In the final stage of making, the trip hook (I4) tip strikes the torsion lever CrlO). However, the trip hook does not disturb making action, since it presses the torsion lever (IlO).in the counterclockwise direction and slides stop the torsion lever (I10) by resisting the spring force. When making action is completed, condition of the ACB is as shown in Fig. 1J. Under this condition, the coupling point of the drive crank (Il) and the coupling bar (I2)--viewed from the direction of the force action--has passed the deaa point with respect to the drive shaft and ensures, in collaboration with the fixing mechanism 6f the operating device, the state of making. In the case of the AC4000A and DC4000A type ACB, also the left and right-hand switching operation mechanisms maintain mutual linkage and respectively perform the above- mentioned actions. Fig. 1J State of Making -28- 2.· Action of ACB by the Operating Devica at Breaking Time {Figs. 11 and 1J) . ·ay·turning th~ operating device in the breaking direction, the drive shaft (Il~) and the drive crank {Il) are rotated counterclo.ckwise. In the initial stag·e of the , . drive crank (Il)·rotation, the left end of the coupling ba~ .. . (12)· only slightly shifts from the making position, its right. end.alone shifting upward in accordance with rotation of the .. J .. ' drive crank (Il). Accordingly, the trip hook (~~) shifts upward, bUt during this movement, its lo~er hook seg~ion catches the hook on the upper part of the torsion lever (IlO}~ causing . -.. ,· :~· . the release shaft (Il~) to rotate clockwise in accoidance with movement of the torsion lever {I)O). f ' The right end of the relea~e lever (IS), due to clockwise rotation of the release shaft (Il~). comes off the creaceht hook of the shaft and drops due .to downward pressure exerted by the roller lever (IJ) and to its own weight. Since the roller lever (I7) is always pr~ssed downward by the free trip lever (I5), it begins to rotate counterclockwise simultaneously with fall of the release bar ci~) and comes off the free trip lever {I§). Thus, the interrupting lever { I6) is released from the constraint of the free trip lever and begins to rapidly rotate counterclockwise, carrying with it the main interrupting shaft ( Il?) due to force of the interrupting ·springs {I~) and (Il2), returning to the opening position. By the rotation of the main interrupting shaft { Il_?) ,· the main contact piece and the arc contact pieces are opened by one {refer to the paragraph) on the main contacting part). The opening movement of the main interrupting (Il?) shaft is stopped by the striking lever (Ill) when it strikes against the projection on the ~ide wall (this condition is the same as that shown in Fig~ 14 exbept for a diff~rence in the position of the drive crank (Il), coupling bar (I2), and operating device). After· the trip hook (I4) has passed the torsion lever (I10), both the trip hook and release lever return to their original posi~ions by force of the spring~ -29- ... _ .. On the other hand, the free trip lever (IS), which has been re 1 ieved of its comb in at ion w.i th the interrupting lever ( I6}, is subjected to the· rotating movement of the driv.e lever ( Il} through the coupling lever (I2) and continues rotating counterclockwise. At the final stage of the opening operation of the operating device, the head roller of the resetting lever (I~) pushes up the release lever {IB), raises its right end and shifts tt above the crescent hook section (!14), and prepares for making. When the right end of the release lever ( I;i) is raised, the lever raises the roller lever. { I·l), causing it to prepare for action corresponding to that of the free trip lever (IS), creating the condition shown irt Fig. 11 • Fig. 14 Condition of Free Trip J. Action at the time of Free Circuit Breaking {Fig. 14) When the release shaft {Il~) is rotated clockwise by action of the undervoltage release or by instantaneous release at the time of making the ACB, the main interrupting shaft (Il§) rapidly rotates counterclockwise in the same manner as in {2) described above, and as a result, the ACB is interrupted .. Unlike the condition described in {2), above, the operating device, drive crank {11), coupling bar .(12}, and free trip lever (IS) are held intact in the making position. Before remaking the ACB from this position, preparation for making the release lever (18), roller lever (I?), and so on must be completed by restoring the operating position. .. -30- When the ACB is made after opening it once, the ON/OFF action mechanism performs the operation_ described in (1)' above. m .

Action at Making time Fig. 16 RFc91J in Thrown Condition While the main interrupting shaft (Il?) rotates counterclockwise, so does the insulated support (S1). As the insulated support rotates, its cam-shaped projection (T1) pushes downward· the roller/ ( R2) of the moving arc contact partr thus, the moving arc contact piece (C10) approaches and finally contacts the fixed arc contact piece (CB). In AC application, further rotation of the insulated support (S1) causes the fixed moving arc. contact •piece to be raised by ·bending the flat spring behind it1 ·in DC application, it causes the spiral spring under the moving arc contact piece to be compressed. After the fixed and moving arc contact pieces have contacted each other, the insulated support (51) ·keeps rotating: as a result, the roller-type moving main contact piece (C2), after having struck the lower main fixed contact part, is wedged between the upper and lower fixed contact pieces (C4) and (C6) and pressed to close the main circuit. 2, Action at Breaking Time As the main interrupting shaft (IlS) rotates clockwise, the contact· roller (C2) follows the rotation of the insulated support (S1), comes off the lower main fixed contact piece (C6), and shifts upward along the upper fixed contact part ( c J). -32- (~ \ Even after the main contact piece is opened, the insulated support (S1) keeps rotating further, its camshaped projection.

As the moving ar·c. ~ontac~· p ieee ( C1 0) is b"eing pushed down, the fixed moving arc contact piece (C8) returns to the opening position in the case of AC application; in the case of DC application, the spiral spring elongates until the arc contact piece opens to open the circujt. N. VOLTAGE RELEASE AND UNDERVOLTAGE RELEASE (Pig. 17 and 20) As shown in Fig. 17, the voltage release and undervoltage release are composed of a mag_~et_ (d1 ),_ ~I}llature (~2), coil {dJ)~ actuating lever (d4~, r~s~t~ini lever. (d5), spring (d6}, and other parts. 1. Voltage Release In the case of a voltage release, the armature (d2) is detached from the magnet. (d1): the former is attracted by the latter when voltage is impressed on the coil (dJ) when an circuit-breaking instruction is given. Pig. 17 Voltage Release -33- This causes the stud constraining the actuating lever (d4) to come off and, by the force of the spring (de) the actuating lever is caused to rotate counterclockwise about point 0 which forms the fulcrum of rotation. The right end of the actuating lever (d4} pushes up the relFase shaft (114 and TJ in Fig. 20) which is thus made to rotate. Rotation of t.he release shaft {114) causes the ON/OFF a·ction mechanism to open the ACB in accordance with .the abovementioned . ll-J (action provided· at the time of automatic circuit-·:·. breaking).· Wh~n the ACB is 'opened, contact.

When the ACB is opened, the resetting cam (T2 in Fig. 20) fixed to the drive shaft (T1J in Fig. 20) presses down the roller of the resetting lever (d5): thereby the action lever (d4) is pushed'up to its original position, and completes preparations for the next release. 2 •. Undervoltage Release In the case:of undervoltage release. voltage is normally impressed on the coil {dJ) and the aumature (d2) is .. norm~lly kept.attracted •. When this voltage is lost or drops ab.normally, ·the armature (d2). is detached and the actuating lever (d4) comes off the stud, causing the OM/Of'F' action rnecnanisrr to open the ACB through the same action-as that for the voltage. release. When the operating mechanism ls shifted to the OPEN position, each part functions in the same mann~r as that of ' . . . the voltage release. In this case, however, the armature (d2) is mechanically attached ~o the magnet {dl), and when a voltage· is impressed on the coil under this condition, the armature {~~) is attracted by the magnet {d1) and the actuating lever (d4) is detained in position by the stud. If no voltage is impressed on the coil (dJ) under this .. resetting condition, and if the rese~ting cam (T2 in. Fig. 20) ·ts .rotated by the making.action of the operating device, the actuating lever (d4) is relieved of constraint. -34- Bi following the movement of the resetting cam (T20 in Fig. 20). the actuating lever ( d4) · is placed under· a released condition and prevents the ACB from making by repeating the abovementioned ~eleasing movement. V. INSTANTANEOUS OVERCURRENT RELEASE (Figs. 1B and 20) As shown in Fig. 1B, this release is composed of a magnet (d7), armature (dB), spring (d9), adjusting dial (d10), and cam (d11) which surround part of the main current-carrying path and the actuating pin (d12) which is fixed on part of the armature (dB) •. · When current exceeding a set value flows, ·the·magnet · ( d7) suddenly attracts the armature (dB) 'J and the ·actuating pin (d12) is ~itted. into the drive shaft (~1~ in Fig. ~O) to provide free rotation. Since the striking lev.er (T4 in Fig. 20) is coupled to the release board (TJ in Fig. 20) with a pin, the actuating.pin begins to rotate the release shaft (T14 in Fig. 20) and the ACB is opened by action of the ON/OFF a~tion ~echanism in the 'manner described in II-J (action during free tripping). When the main current is interrupted, magnetism of the magnet (d7) is cancelled and the. armature (dB) is reset by the spring (d9). The gap between the magne.t (d7) and the armature (dB) can be adjusted via the cam (d11).by the adjusting dial (d10), and thus, the release current value can be adjusted within . a certain·range.(· Incidentally, the length.of the actuating pin can be adjusted through a hole on the front panel. ·Fig.:1B Inverse-time-limit Overcurrent Release dto rltt Y.L INVERSE-TIME-LIMIT OVERCURRENT RELAY (THERMAL RELAY} As shown in Fig. 10, the inverse-time-limit overcurrent relay for AC application has a converter (d1J} on part of the main circuit, whose secondary current-~led to the thermal relay mounted on the ACB body--is caused to function. As shown in Fig. 19, the inverse-time-limit overcurrent relay for· DC application consis~s of thermal relay (d14J,~nd a h~ater board (d15), in which the main current flows directly through the heater board (d15}, the heat thus genera1ed actuating the thermal relay. Both the AC and DC types open the ACB by operating the voltage release or the undervoltage release through . actions of their relays. Both the AC and DC thermal relays having an ambient temperature compensating devide, the release current value can be adjusted within a certain range hy rotaing ~he adjusting dial (d16) which modifies the gap between contacts.

The auxiliary. switchgear is ·mounted on the right below the front panel (D in Fig. 9)~ Movement of the main inierrupting.shait (llSin Fi~. 12) . is transmitted to this switthg~ar through ·a transmission link mounted on (U) i~ iig: 9~:the ~tri~in~ lever (I~1 i~ Fig. 12), and a~ a. result, ihis ~witchgear performs ON/OFF operations associated ·with the main contact piece.

Manual Operating Device (fig. 4) Employed ~hcnever direct manual operation is feasible. 2. Motor-operated Device (1) Particul~rly suitable for remote operation and can be used on AC or DC. -37- It can be operated directly by a control switch or by contactors etc., particularly when it is remote-operated. (2) Its construction is as shown in Fig. 21 which illustrates the condition of breaking. When the making switch is thrown under this condition, the moto~ (f1),rotates the worm (f2) and the wotm gear (fJ). The actu.ating pin (f4) secured to the worm gear (fJ) rotates with the worm gear, wedging in the notch· of the operating board (fS) which is pushed to the left. f 1 : Operating ~otor f21 Worm : fl f): Worm gear f4: Actuating pin f51 Operating board f" f6: Casing f7: Operating rod f81 Terminal switchgear f2 f91 Interlocking fa contact f7 {11 f1 0: Bevel gear f 11 : Emergency operating handle I 1: Drive crank I1J: Drive shaft Fig. 21 Motor-operated Device (Condition of Completed Breaking Action) -38- Since the -left-hand end of the operating board (fS) is cou~led to the d~ive crank (I1), the drive.shaft (I1J) is ultimately r9tated through the drive crank (I1) to provide making action of the ACB. The ON/O~F indicator, which interlocks with the operating bo~rd ( f5)!. is mounted on the side of the casing (f6) to indic~te the ever-changing p9sition of the operating device. Immediately before completion of making action, the operating rod (f?) coupled to the drive crank (Il) opens the contact of the final making switch (f8) to disconnect the circuit of the motor (f1) which continues rotating by inertia. When the worm gear (fJ) completes making action by turning through an angle of about 180 degrees from the position shown in Fig. 21, the actuating pin (f4) comes off the notch on the operating board (f5), and the worm gear continues rotating freely until its inertia is.exhausted. At this time, the indicator on the side of.the-.c~si~g-(f6) indi6at~s the OPEN position. When breaking the circuit, rotate the worm gear (fJ) counterclockwise by throwing the breaking switch to rotate the drive shaft (I1)) counterclockwise. Whe~ breaking action has ~regressed to a certain extent, the ACB ls sudde~ly interrupted independently of the speed of the o~erating device (refer to II-2 mentioned above): Immediately before the completion of breaking action of the ACB, the final breaking switch disconnects the circuit of th~ motor (f1) by action of the operating rod (f?), causing the motor to continue rotating by inertia. Breaking action of the ACa completes at the position shown in Fig. 1), and subsequently the actuating pin {f4) comes off the operating board (f5) and the worm gear continues freely rotating until its inertia is exhausted. When the ACB has made free breaking, it cannot be thrown until the free trip mechanism has been reset by restoring the operating device to the OPEN position. When the motor (fl) or the operating circuit is out of . order, handle the operating device by using the emergency o;erating handle (f11 ). -39- ~y axially pushing the emergency operating handle, the operating circuit for the motor (f1)·is opened by the interlocking contact (f9), and the operating handle (!11) is concurrently coupled to the worm (f2) through the bevel gear {f10).' Under.this condition, by rotating the operating handle {f11)·clockwise, the worm gear (fJ) is rotated clockw.ise to accomplish making act ion. At .. ' this time, the ON/OFF indicator· on the side of the. casing .also indicates the condition of the operating device. To interrupt tb~ ACB, rotate the operating handle counterclockwise by keeping it pushed axially. At14'000'A ( J). The oL!E'OOOA Type ACB is equipped with two set_s of the operating device whose construction is described in item (2): since the motors of each set are coupled to each other, ·the two operating devices provide an integral:function. Their action is the same as item (2). · IX CONSTRUCTION AND OPERATION OF DRAW-OUT TYPE ACB 1. Construction {1) As shown in Fig. 22, the draw-out type ACB consists· of the ACB body (b) supported on a dolly (a). The main terminal part, consisting of tulip contacts (c), forms the disconnecting part along with the fixed contact ~od on the panel side. The ACB can be pushed in and withdrawn from the panel by operating the handle (n). By pushing in or withdrawing it, the main circuit can be connected or disconnected. {2) The .terminal (h) for the auxiliary contact piece circuit is mounted on the left side of the front panel. It is equipped with a contact rod and forms the disconnecting part along with the fixed contact piece (4) on the panel side. It can be interrupted by pushing in the handle (i). (J) When resetting the short time limit release, move the reset lever (1) on the front panel from the trip position to the reset position. -40- ( \ .I- . When the short time limit release has tripped, the . reset lever indicates the trip position •. ·.:. ,·· : (4) When electrically pper~ting,the operating ~evi~~· usually ~emove the emerg~ncy manual·handle (o) and mount it only when necessary. ~Its handling. procedures are the sam~~as those for the ~tandard~·. one. (S) This type is equipped with an interlocking roller {f). When the ACB shifts from a testing position to an operational one, interlocking is achieved by a guide {2) on the panel side. (6) By pressing the manual trip push button (m), the ACB can be tripped. When pressing the manual trip push button to adjust it to the locking position, ·it locks, keeping the ACB locked. By adjusting it to the locking position without pressing it, the button cannot be press~d. a~d t.he ACB co·ri~ot be tripped. (7) The operating element (j) of the limit switch for the testing position is mounted on the right side of the dolly (a); the operating element (k) of the limit switch for the operational position is mounted on the left sid~ of the dolly. Thus, by installing limit switches within the panel, utilize this system for interlocking and other actions. 2. ·ope rat ion (1) When housing the ACB within the panel, the following preparations are necessary: insert the handle (n) in the shaft (d) for the operating handle and turn the handle counterclockwise to bring the moving nut (e) to the rearmost positinn. (2) Make sure the moving nut (e). is at the rearmost position, and after having drawn out the handle (i) of the auxiliary contact terminal (h) completely toward you, push in the draw-out type ACB which is placed on the track (5), until the moving nut (e) is locked by the locking device (J) on the panel side. -41- When the moving nut is locked by the locking device,.the position pointer (g) comes to the testi~g position shown on the position indicator (6) pn the panel side. At this position the disconne~ting part is detached. (J) After confirming that the position indicator (g) is at the testing position, press the handle (i) of the auxiliary contact rod terminal (h) so that the contact rod (h) of the auxiliary contact is compl~tely inserte~·~ri.the fixed contact part (4) of the auxiliary contact piece on the panel side. This procedure completes preparations for testing the ACB. (4) Run an operational test for the ACB, and after confirming that there are no signs of an abnormal condition, insert the handle (n) in the operating handle clockwise until the position pointer (g) comes to the operational position shown on the position indicator (6) on the panel side. At this position, . . the main terminal disconnecting part is completely connected ·and the disconnecting part of the auxiliary contact piece.cannot be detached.· Since this completes preparations for making the ACB, throw the ACB by closing the door of the panel. Even if the ACB is made by mistake during its shifting from the testing position to the operational one, it cannot be thrown because the interlocking device is in operation. Be careful not to make the ACB until the position pointer has come completely to the operational position. (5) When drawing out the ACB from the operational position to the testing position, after interrupting the ACB, insert the handle (n) in the operating handle shaft (d) for drawing out, and turn the handle counterclockwise until the position pointer (g) comes to the testing position shown on the position indicator on the panel side. -42- \'ihen the position pointer has come to the testing position,_ the terminal (h) of the auxiliary contact piece is :in a connected condition.

Construction (1) Open type 300r000 operations 100,000 operations at 220 V AC 5 A The NS387 control switch consists of a contact unit and an actuating unit. The contact unit is composed of a fixed contactor and a moving contactor. The shape of the moving contactor, the mounting angle and the number of contacts are determined according to applica- tions. The actuating unit is classified into the auto-reset type, manual-reset type, and auto/manual reset type. Each of these types can be combined with handle lock, microswitch, etc. The auto-reset type is normally provided with a handle lock. When the handle is pulled forward and turned, the moving contactor is actuated. When the handle lock is released, t~e moving contactor is reset automatically to the original position (center position). The manual-reset t~pe has one set of notching device 2 (star wheel,· roller, lever; spring, etc.) on the handle shaft to indicate the setting position of the handle. The 2-position manual-reset type with six-step contacts is provided with a notching device on the front and back of the switching element. (2) Cover-mounted switch This switch has an acryl resin transparent cover to prevent accidental access of hands and tools to the live parts of (-the contact unit. (3) Oil-immersed type The oil-immersed type is used in places with corrosive gases such as chemical factories to prevent deterioration of the switching element. Like the open type, it is available in the auto-reset switch, manual-reset switch and ammeter/voltmeter select switch, each having a maximum of 4-step contacts and 3 notches. 3 5.

Composition of contact It is as follows, from the side of the handle: 1. The standard contact at the right angle to the direction of the handle (to be in parallel only in case of 4-point changeover) . 2. · The standard contact at 45° right from the above contact. 3. The no-breaking contact at the right ~ngle to the direc- tion of the handle (to be in parallel only in case of 4-point changeover) . 4. The residual contact.

Following is an example: left·h;~nd side<:--->right·hand side passive oper.ltion posith·e operation ... _ ----·----~ ----··~-------------- stop stop 1 off stop individual low speed manual low speed 2 on operation interlock high speed automatic high speed 3 reverse run stop normal run deceleration retain acceler.!tion fall stop rise backward stop forward ··-· ---·-. ---·-------·---- 14. Example of connection diagram Following is the connection diagram of NS387S/lmH in use for making circuit and alarm circuit. 13 Haking circuit: 1. When the handle is turned to "ON", 1 and 3 are connected and MS is closed. Even when the handle returned to "zero", HS will hold i tse.lf by MSa. 2. When the handle is turned to "OFF", connection between 1 and 4 will be cut off and MS will be disconnected. Alarm circuit: 1. When the handle is turned to "ON", 5 and 7 will be con- nected. In this case, the bell will not sound, because HS is closed and NSb is open. 2. When the OLR operates, NS is disconnected and MSb is closed, and the bell will sound for alarm. 3. When the handle is turned to "OFF", 5 and 7 will be dis- connected and the bell will stop. 15.

The DGF relay provides a reliable means for detecting grounds in the de winding of the ,nerator field. It uses a voltage divider con· ;ting of a resistor and varistor connected across the field winding of the generator. The relay operating coil is connected from the mid-point of the voltage divider to ground. A ground in the generator field winding will cause current to flow through he moving coil of the DGF and operate the elay to trip or sound an alarm, as desired. Operation The DGF relay scheme does not require an external voltage source. It consists of a sen· sittve d'Arsonval type de relay (.75-0-.75 milliampere), and suitable resistors. As shown in the internal wiring diagram (Figure 1 ). the relay utilizes a voltage divider circuit consisting of linear resistors R, and R;• . and a non-linear resistor (varistor) whose resistance decreases as the voltage applied across the resistor increases. If the field becomes grounded, a voltage will exist between point M (Figure 2) and the ground point. This voltage will vary depend· ing upon the magnitude of the exciter volt· age, and also the point where the field is grounded. The voltage will be maximum if Wto;ting .. ouse E:e .. tric:Corporation Relay-Instrument Division Coral Springs, Florida 33060 For Generator Field Protection Descriptive Bulletin 4 1-745C Pagel Type DGF Field Ground Detection Relay Internal Wiring (Front View), FT-21 Case I .. . ·.

A null point will exist in the field winding where no voltage will be developed between point M and ground. If the divider .resist· ance between M and the positive side of the exciter is equal to the divider resistance between M and the negative side of the exciter. the null point will be at the center of the field winding. The non·linear resistor varies the lo.::ation of the null point as the exciter voltage varies. so that a ground can be detected at any point in the field wind· ing. The voltage characteristic of the non· linear resistor is shown in Figure 4. In the 250 and 375 volt types an additional resistor (R,) is connected in series with the varistor to protect it from overvoltage. The voltage divider is so proportioned that the field winding null position is located i!t mid-poir.t when the field voltage is at 100% of rating; or at the 25% point from the negative end when 30% of the rated voltage is ap;Jiied to the field. The outer curves in Figure 3 indicate the increase or decrease in supply voltage to close tile relay contacts lor a ground at the null point.

While overload relays will eventually detect this cond:tion, the motor should be quickly disconnected when severe low voltage conditions exist. Where contin- uous operation is essential, such as station auxiliary service or continuous manufactur- ing processes. the CV relay is used for alarm purposes only. V •age Transfer Schemes " '·' alternate sources of power exist. such as double-ended transformer units, the CV relay can be applied to initiate switching of the station bus to the alternate source. The CVD relay is used in control circuits to initiate switching when the line voltage in- creases or decreases beyond a predeter- minec;f value. CV-21 to CV-27 relays are frequency com- pensated. and maintain a fixed pickup volt· age over a wide range of frequency. They are used in hydro machines. Timing Applications The CV relay has an accurate operating time characteristic over a wide 1anoe of time dial positions and minimum operating voltages. It is frequently used where specific time intervals are required after application of normal voltage or the increase or decrease from normal vol:age. Induction Motor ,. ·lervoltage Protection • ng transistory faults, such as lightning strokes. an overhead line may be momen- tarily de-energized while the fault arc is being extinguished. During this period it is desirable to prevent disconnection of the motor load, and realize maximum benefit from fast reclosing schemes. Time delay CV relays are used to keep the motor load in service. Ground Fault Protection of Ac Generlltor Windings The single unit CV-S relay provides effective ground fault protection for generator stator windings. It is relatively insensitive to third harmonic (1 SO henz) voltage. and will not operate for third harmonic load unbalance which normally flows in the generator neutral. The CV-S has a 60-hert:z pickup voltage of 8% of rating, and provides good sensitivity for light ground faults in the machine. Features low burden due to high efficiency of "E" type electromagnet. Small size FT·11 case permits optimum use of panel space. Frequency compensated designs having a variation in pickup of less than 5% over the frequency range of 30 to 90 henz. applied on hydro operation. Variety of designs available including units with single, double, or single-pole double-throw contacts with de or ac seal-in units or instantaneous voltage units. Harmonically restrained CV-8 relay pro- vides excellent ground fault detection of· generator stator windings. Device Numbers CV-1, CV-2. CV-21. CV·22 ••••••••••••• ll_ CV-~.

E) Right Stationary Contact On CV-6, 7, 26, and 27 relays, the left (front) stationary contact is closed at tap value voltage, and the right (back) con:act will close at a lower voltage which is within 5% of this value. 0 Time Dial Indicates initial position of the moving con- tact. It is indexed from position % (mini- mum time) to 1 1 (maximum time). See time curves, pages 4 and 5. f) Damping Magnet High strength Alnico. Used for camping the induction disc. CV-1, :Z, 4, 5, G, 7 These relays consist of a voltage unit em- ploying the electromagnetic induction disc construction (as shown in figure 1 ), and an Indicating Contactor Switch unit (ICS). See Per!or;nance Data ~ 1 • 100 . The voltage unit consists of an ··:;" shaped laminated core which has a main tapped coil and a shading coil on one of the outer legs to shift the flux out of phase. In operation. the out-of-phase .flux interacts with the main coil flux to create a torque on the disc. Rotation of the disc is opposed by a spiral spring which resets the contacts and disc to their normal position when the applied voltage falls below the tap se:ting value. The voltage values indicated by the tap plate are the minimum voltages required to close the relay contac:s. On overvo!:age rP.Iays tYPes CV-4 and CV-5, the contacts close at tap value or above. On undervoltage types CV-1 and CV-2. the contacts open at tap value or a~ove. On the over and undervoltage types CV-6 and CV· 7, the tap value is the voltage at which the relay's front contact closes. The back contact will close within 5% of this value. CV-8 The CV·8 uses the same basic induction ' I Figure 1-Voltage Unit (CV Relays) Figure 2-Type CV·4 Relay-Front View, Chassis Figure 3-Type CVD, Chassis View . -; Indicating Cornac1or Switch Descriptive Bulletin 41·200 Page 3 disc voltage unit and Indicating Contactor Switch as types CV-1 to CV· 7, but in addi- tion includes a built-in capacitor connected in series with the electromagnet coil to filter out third harmonic voltage. It is designed for low pickup value (8% of continuous voltage rating) in generator Ground fault detection schemes. Additional data on this application is given on page 6. CV ·21, 22, 24, 25, 26, 27 These relays employ the same basic indue· tion disc voltage unit and Indicating Con· tactor Switch and operate similar to wpes CV-1 to CV-7. except that they include a frequency compensating resistor connected in the outer leg coil circuit of the "E" type electromagnet. The compensating resistor enables them to maintain their 60 cycle pickup voltage and/or dropout values with· in 5% over a variable input frequency of from 30 to 90 hertz • Their contact arrangements and characteris· tic curves are the same as those for the com- parable CV-1 to CV-7 types. cvo(Fig. 3) Type CVD incorporates the same basic elec· tromagnetic induction disc voltage unit used in the CV-1 to CV-7 types, but is con· structed to operate essentially as a contact making voltmeter, with high and low volt· age contacts, which are independently ad· justable over a calibrated scale. Upon application of vol:age to the relay, the disc moves to a positiOI) in its travel that corresponds to the applied voltage. and remains in this position until the applied volt· age changes. It then moves to a position corresponding to the new voltage value. Since the movement ol :he disc from one position to another is under the control of the restraining spring and the damping magnet. the relay has inverse timing char· acteris:ics. ihe greater t!le change in applied voltage, the faster the relay disc and moving contact will travel. ICS, ACS, and IIV Units ICS: The Indicating Contactor Switch is a de current operated device having a mag· netic armature to which leaf-spring con- tacts are a:tached. When energized at pickup value. the moving contacts bridge the stationary contacts and seal in around the main relay contacts. relieving them of carrying heavy trip curren:s. The switch has a target which indicates completion of the trip circuit. ACS: Similar to the ICS unit. except tha: it is ac current operated. IIV: Also similar to the lCS unit. except that it is ac vot:age operated Refer to ?ertormance Data 41-100 for fur- ther details.

The primary of the transformer is rated for generator line-to- line voltage, secondary lor 120 or .2.,40 volts. A CV-8 low pickup relay is usedto detect • ground fault in the generator winding. The relay contains a tuned filter circuit which of- fers high impedance to 180 hem voltage (third harmonic) and low impedance to 60 hertz voltage. The 67 volt CV-8 relay can withstand 67 volts continuously and 140 volts for 2 min- utes. If the relay is to be used lor an alarm or a timing function where the above val· ues are exceeded, if is advisable to use the 199 volt CV relay. If however, a more sen- ···•ve pickup is required, a 67 volt relay may used in conjunction with one SV relay and an external resistor as shown dotted on figure 1 0, Using a 70-1 60 volt SV relay and a 375 ohm, 8~-inch external resistor, the combination is rated a: 1 60 volts continuous. R2 resistor assembly is style number 1956 449. At 70 volts. the SV relay picks up, opening its contact, and inserting the resis- tor in series with the type CV-8 relay. thus reducing the voltage impressed across the CV-8 coil. Due to the high impedance of the CV·8 during generator warm-up or reduced fre- quency operation. an additional adjustable SV relay rated 7 · 16 volts, 60 hertz is used to back up the CV-8. The SV is set to initiate tripping. With a 7 volt. 60 hertz setting. it will opera;e at 2 volts. 15 hertz or 3.5 volts at 30 her:z. During 60 hertz operation. the SV relay is disconnected by a 52b contact. A third harmonic filter circuit is not required with the SV because of the low values of third harmonic present during reduced fre- quency operation.

Applications and operation 1.1 For ~eneral control circuit (Type: DRHHB ( ) C ( . ) , DRHHB ( ) D ( ) , DRHHB ) s ( ) J A basic type of DRHHB series with SC (5 pairs of change-over contacts) contacts having 30 VA of ca- pacity used for general control circuits. The DRHHB ( )C( ) type is a single coil type operat- ing on the rated DC/AC voltage, while the DRHHB { )D{ ) type is a double coil type with an operating coil which operates on the rated DC voltage and a holding coil which ~olds on the rated voltage or current. The DRHBB { )S{ ) type is a single coil type operating on the rated DC current. On the double coil type operating on the rated DC voltage, the relay holds its operating condition by applying a holding input to the holding coil even when operating coil input is absent.

Maintenance and inspection 4.1 Inspection intervals The auxiliary relay is simple and rigid in construc- tion and provides high reliability, eliminating the need for frequent maintenance and i~spection. Inspection intervals depends upon the contact Cp- pacity; for example, the relay should be inspected after about 300,000 operations when used at about 1/2 of the maximum capacity or once every 2 years . when the operating frequency is less than about 300,000 operation i.n 2 years. 4.2 Visual check 1} Contacts Contacts are subject to wear, discoloration and contamination while in use. Check the relay for abnormal wear and discoloration or seizure and deformation. When the contact performance is normal, the relay is available for further use.· 2} Coil Check the coil for discoloration, burning and overheat. 3} Mechanism Check the mechanism for deformation, discolora- tion, corrosion and loose screws. 4.3 Inspection and maintenance of electrical characteristics 1) Operating value and resetting value The voltage rating coil operates at less than 80% of the rated voltage and resets at more -19 - than 10%, except for DRHHB at more than 5%. )V ( ) which resets The current rating coil operates at less than 100% of the rated current and resets at more than 20%. The coil is heated with over-input, so it should be used within the continuous withstand value shown in the specifications. 2) Contact resistance Apply a current of 100 rnA to the contacts from 6V DC power. When the voltage drop at the con- tacts is more than 200 mV (2Q), polish out the contact face with a smoothing leather or the like to reduce the contact resistance. 3) Insulation test i) Insulation resistance Check the following items using 500V DC megger at less than 90% of relative humid- ity.'

No modifi- cation of contact composition in any combination is possible except for Types SRC3631-5-1, SRCS0-4, and WRCaS0-4. Types SRC3631-5-1, SRCS0-4, and WRCS0-4 can be modified regarding their contact compositions only in a predetermined range. However, contact composition of SRCS0-4 cannot be modified to that of SRC3631-5-1 nor can the contact composition of SRC3631-5-1 be modified to that of SRCS0-4. (3) Coil Permissible voltage variation is 85- 110% of the rated voltage as deter- mined in JIS*. 1) When voltage is too high, shock caused by attraction becomes large, not only imparting an adverse in- fluence to each section but also overheating the coil, thus shortening its durability. 2) When voltage is too low, attracting force of the electromagnet becomes short, generating a beat in the electromagnet; or a melting phe- nomenon may be generated due to weakened contact pressure of the contactor. Consequantly. pay at- tention to employing the auxiliary relay within the permissible voltage range. J) Contacting surface of the magnet core When wire chips or iron chips enter the main body while installing wir- ing of the panel installation, this foreign matter will cause heating of the electromagnet should such matter enter the core contacting surface. If beat of the electro- magnet is generated due to dust, remove the dust by wiping the contacting surface. When rust accumulates on the con- tacting surface due to a long suspension of operation, remove rust by wiping with a dry cloth. • Japanese Industrial Standards.
