S280-30-3, Page 3 MAINTENANCE NOTES Page44 Page DESCRIPTION 5. Hydraulic Pump and Lockout Piston Operation Each time the recloser trips,the hydraulic pump makes one stroke, forcing a measured amount of fluid under the lockout piston. Thus, the lockout piston advances a definite amount after each recloser trip operation. The lockout piston in turn advances a lockout bar. After the selected number of fast operations, the series trip solenoids engage the time-delay units. When the selected number of repeated trip operations has occurred, the lockout bar prevents reclosing; the control lever unlatches to signal that the recloser has locked open. The Type W recloser is a self-contained device that senses single- or three-phase fault currents and interrupts simultaneously all three phases of a distribution circuit. The recloser automatically recloses to restore service if the fault is temporary and then resets for another cycle of operations. If the fault is permanent, the recloser locks open after one, two, three, or four operations, depending upon its adjustment. Opening sequences of the recloser can be all fast, all slow, or a combination of fast and slow. When a combination sequence is used, fast operations always precede slow operations. On coordinated systems, fast recloser operations are used to clear temporary faults before branch-line fuses are damaged. Subsequent slow (time-delay) openings allow fault currents to flow long enough to be cleared by branch-line fuses or reclosers. Thus, outages due to permanent faults are limited to shorter sections of line. The basic recloser functions described above can be modified by one or more accessory devices designed for the Type W. For complete information about these devices, refer to the recloser installation manual and the bulletin covering recloser accessories. 6. Series Trip Solenoid This device in each phase carries full line current. When current greater than the minimum trip value flows, the solenoid plunger moves downward, causing a recloser trip operation. When delayed openings are called for, each plunger is restrained by a time-delay unit, and thus requires more time to trip the recloser. 7. Time-Delay Unit A sealed time-delay unit for each phase provides consistent delay action by forcing hydraulic fluid through an orifice. Special fluid minimizes temperature effects. COMPONENT FUNCTIONS See figure 1 to locate components. GENERAL MAINTENANCE INFORMATION 1. Arc Interrupting Assembly Why Heart of the W recloser is a rugged arc-interrupting assembly for each phase. Circuit opening is achieved by the double-break moving contact assembly. Reclosers are widely applied to increase service continuity, reduce system operating costs, and increase revenue. The Type W performs all these recloser functions, and also meets requirements for many new applications. However, the W can perform at peak efficiency only if it is maintained in good condition. Maintenance is relatively easy and inexpensive; it is important. 2. Closing Solenoid Moving contacts are closed by the closing solenoid which also extends the opening springs located in the head assembly. This solenoid is energized only a few cycles during each closing operation when it is momentarily connected across two phases. 3. Closing Solenoid Contactor Snap-action contacts complete the circuit to the closing solenoid for each closing operation. 4. Fuse Two fuses protect the distribution line from any possible fault in the closing solenoid. Oil plays an important role in several recloser functions. It is essential in arc interruption, insulation, counting and reclosing. Arc interruption, however, contributes to oil decomposition. For this reason, the oil steadily diminishes in quality as the recloser continues to clear fault currents. Breathing action may also result in moisture absorption by the oil, thus lowering its insulation value. For effective recloser operation, oil must be reconditioned or replaced before it deteriorates beyond a safe level. S280-30-3, Page 5 FIGURE 1 Principal components, Type W recloser. Page 6 GENERAL MAINTENANCE INFORMATION - CONT'D. When Frequency of maintenance of the Type W depends upon local climatic conditions and the interrupting duty imposed upon it. M-E recommends the unit be completely inspected, cleaned, and filled with new oil at least once a year. If the Type W operates through a duty cycle in less than one year, the periodic maintenance should be performed then. The proposed NEMA standard duty cycle for power-class III reclosers is as follows: Number of Recloser Operations Rating 28 20 10 Total 58 Fault Current, Percent of Interrupting X/R Value Maximum Circuit 15 to 20 45 to 55 90 to 100 3 7 14 The Type W can go through the complete duty cycle without requiring an oil change. If the majority of fault currents interrupted are near the maximum rated value, more frequent oil changes will be required. Oil that has become contaminated with carbon and sludge, or has a dielectric strength of 18 kv or lower, should be replaced or reconditioned by methods described in M-E Reference Information R280-90-1. Refer to “ASTM Methods of Testing Electrical Insulating Oils,” Publication number D117, for information about testing insulating oil. This publication is available from the American Society for Testing Materials, 1916 Race Street, Philadelphia, Pennsylvania. 3. LOWER THE TANK Attach sheaves of the tank hoisting mechanism to the recloser tank and take up slack. Remove the ten head bolts. CAUTION: Be sure the recloser is tripped before lowering the tank. Thus, the recloser will not be accidentally tripped while the mechanism is out of the oil. Lower the tank to expose internal components. 4. INSPECT MOVING CONTACTS Arcing tips of the moving contacts can experience considerable erosion before replacement is necessary. The contacts should be replaced before their effectiveness is impaired by erosion of contact surfaces. Figure 2 shows a set of moving contacts after they have experienced severe interrupting duty, and a new set for comparison. The used contacts should be replaced. If moving contacts appear to have further useful life, inspection of the arc interrupter chamber and stationary contacts can be omitted. These components are designed to last at least as long as the moving contacts. Where Routine inspection, minor maintenance, most adjustments, and replacement of oil can be performed on a recloser without removing it from the mounting frame. Repairs or major maintenance work should be performed in the shop. PERIODIC FIELD INSPECTION AND MAINTENACNE Each periodic field inspection and maintenance should include at least the following steps: 1. BYPASS, TRIP AND DE-ENERGIZE THE RECLOSER 2. INSPECT EXTERNAL COMPONENTS Check for broken bushings, paint scratches, or other mechanical damage. FIGURE 3 Moving contact set; Left, after one full duty cycle; right, new. S280-30-3, Page 7 5. INSPECT STATIONARY CONTACTS If moving contacts of any phase or phases are in questionable condition, the corresponding stationary contacts should be inspected. Refer to Shop Maintenance section for instructions on removal and reassembly of the fiber plates that form the arc interruption chambers. Removal of these plates is necessary for inspection of the stationary contacts. Figure 3 shows a stationary contact assembly after one duty cycle and a new assembly for comparison. Note that erosion of the load current contact surfaces has started. The six contact segments or the entire assembly should be replaced. FIGURE 3 Stationary contact: Left, after one full duty cycle; right, new. FIGURE 4 Fiber parts of arc interrupter assembly. Reclosers below serial no. 2001 6. INSPECT ARC INTERRUPTER CHAMBERS— (Reclosers Below Serial No. 2001) When stationary contacts are inspected, check fiber plates of the arc interrupter chambers. These plates are stacked as shown in figure 4. The twelve 1/8-inch plates have a slot cut on one end to form exhaust ports. Each arc interruption causes some erosion of these slots. Plates should be replaced when the arc interrupter chamber wall is reduced to 3/4-inch, measured along the shortest side of the exhaust port slot, as illustrated in figure 5. Erosion of the slots in the fiber plates results in longer arcs being drawn. Greater arc energy must then be dissipated during each interruption. Test results indicate the W can successfully interrupt rated current when the arc chamberwall is reduced to the above 3/4-inch dimension. Thus, if fault currents are well below maximum rated currents, some further erosion can be tolerated. FIGURE 5 Vulcanized fiber plate from interrupter assembly. Reclosers below serial no. 2001. Page 8 PERIODIC FIELD INSPECTION AND MAINTENANCE - CONT'D. from the top of the tank with the mechanism removed. The level can be double checked with the oil level gauge after the mechanisms and head casting have been fastened in place. (Reclosers Above Serial No. 2000) The insignificant cost of the fiber plates making up the arc interrupter chambers on all reclosers above Serial No. 2000 permits complete replacement whenever the stationar y contacts are replaced. A visual comparison of bottom and top plates will indicate necessity for replacement. The top plates closest to the stationary contacts and nearest to the most arcing will show enough erosion to provide a decision for replacement. 11. REPLACE TANK Wipe clean the O-ring head gasket and the tank gasket seat. Move the control lever to the closed position to avoid any possible binding while raising the tank. Position the tank so the special “Caution” nameplate on one end of the tank is on the same end as the sleet hood and control levers. Raise the tank and replace the ten head bolts. 7. CLEAN ALL INTERNAL COMPONENTS Remove all carbon traces by wiping with a clean, lint-free cloth. Pay particular attention to all insulating members. Flush the mechanism with clean, dry transformer oil. 12.CHECK OPERATION COUNTER, CONTROL LEVER, CONTACT POSITION INDICATOR, AND NON-RECLOSING LEVER Correct operation of each of these components can be observed by manually operating the recloser. CAUTION: Never use volatile solutions, detergents, or water-soluble cleaners. 13. MANUAL OPERATION After the tank has been filled and secured in position, the recloser should be operated manually a few times to ensure that the dashpot and hydraulic pump are filled with oil. Remove the closing tool port cover and gasket and insert a KA90R closing tool. Manual operation can now be achieved by closing with the KA90R tool and tripping with the manual control lever. See figure 6. 8. DRAIN OLD OIL Remove the 1/2-inch plug at the bottom of the tank, or open the tank valve if one has been installed. Rinse the tank with clean oil, and wipe out all carbon traces with a clean lint-free cloth. 9. INSPECT TANK LINERS Any soft or spongy areas in the liners indicate moisture has been absorbed. These areas are most likely to occur near the bottom of the tank. Replace any liners that appear to have absorbed moisture. When replacing liners, be sure the new liner installed in each section is the same size as the original. CAUTION: Never use the KA90R tool on an energized recloser. For reclosers below Serial No. 2001 the liners are parts numbered KA26W (order two of these), KA27W, and KA30W. See Parts List, Page 21, items 73, 74, and 75. For reclosers above Serial No. 2000, replacement liners come in a kit; the part number is KA867R. See Parts List, Page 27, item 71. If interrupting duty is severe, the tank liners may be eroded near the exhaust ports of the arc interrupting structures. Replace any liners that show appreciable erosion. 10. FILL TANK WITH OIL Use only new transformer oil with dielectric strength of at least 26 kv, as measured across a standard . 1-inch gap in accordance with methods illustrated in ASTM Publication D117. The oil level should be 2-1/4 inches FIGURE 6 Manual closing with the KA90R tool. S280-30-3, Page 9 If a Type W is to be operated out of oil, use the closing tool to open the contacts. While one person turns the tool clockwise against the stop, another can move the trip lever, indicated in figure 7, to the right. Now let the tool slowly rotate counter-clock-wise to open the contacts. Turn the tool 1/4 turn clockwise to close contacts. Replace port cover and gasket when manual operation is completed. FIGURE 8 Removal of arc interrupter assembly. Reclosers below serial no. 2001 FIGURE 7 Trip lever, releases recloser when opening with closing tool. SHOP MAINTENANCE When shop maintenance or repairs are to be performed, remove the ten bolts that secure the tank and head castings. With suitable hoist, raise the recloser mechanism out of the oil and allow it to drain. The recloser can be left suspended by the hoist, inverted and placed on a workbench, or the mechanism frame ends can be supported by a special rack. ARC INTERRUPTER ASSEMBLY (Reclosers Below Serial No. 2001) After the Type W recloser has operated through a complete duty cycle, the arc interrupter assembly should be completely dismantled and any worn parts replaced. 1. Using a 1/2-inch thin-wall socket, remove selflocking hex nut that secures contact yoke to the lift rod, as shown in figure 8. Gently tap contact arm to remove contacts from the lift rod. NOTE: Pin in the rod must be aligned with a slot in the contact yoke. 2. Disconnect heavy braided lead or the solid strap from the top of each stationary contact assembly. 3. Remove hex nuts, flat washers, and lock washers from bottom of interrupter assembly. FIGURE 9 Components of arc interrupter assembly. Reclosers below serial no. 2001 4. Slide the arc interrupter assembly downward. Figure 9 shows the individual parts in the order of removal. Page 10 SHOP MAINTENANCE - CONT'D 5. Examine the stationary contact segments to determine if arc erosion has spread to the load contact surfaces. If so, the contact segments only, or the entire stationary contact assembly should be replaced. 6. Clamp the large end of the fiber tube in a smoothjaw vise. Apply enough pressure to deform the tube slightly so that the contact receptacle is also clamped. With an adjustable wrench turn the large terminal nut on the opposite end of the stationary contact assembly counterclockwise to loosen. Insert a large screwdriver in the slotted contact stud located inside the contact assembly. The large terminal nut can now be completely removed. Pull and turn the contact segments to remove them. Figure 10 shows the contact assembly completely dismantled. FIGURE 11 Assembling stationary contact. Reclosers below serial no. 2001 tube. Position the washer on the opposite end, and secure entire assembly with the terminal nut. Use a screwdriver to hold the contact stud while tightening the large terminal nut. NOTE: Installation of the steel spring on each stationary contact assembly can be simplified by the use of a tapered wooden sleeve that can be made easily in any woodworking shop. Simply turn and drill a piece dimensioned as shown in the sketch. Slip the sleeve over the end of the heavy screw and roll the steel spring in place. FIGURE 10 Stationary contact assembly components. Reclosers below serial no. 2001 7. To reassemble stationary contacts, arrange the six segments so they are hooked to the slotted head of the contact stud. Use a rubber band to hold them in place while installing springs. Slip the steel spring on first, then a spacer ring, copper-alloy spring, spacer ring, and the other copper-alloy spring. Insert segments in the contact receptacle, figure 11, by twisting and pushing. Replace the contact receptacle in the fiber 8. Check condition of the twelve slotted 1/8-inch fiber plates and the 3/8-inch laminated phenolic plates to determine if they should be replaced. Refer to periodic maintenance, page 5, for the method of determining when these plates should be replaced. 9. Examine the insulating support stringers for evidence of tracking or moisture absorption. Failure of these members is rare, but if any show tracking, replace as follows: a. Disconnect flexible leads attached to the seriestrip solenoid coil tab. S280-30-3, Page 11 b. Remove the hex nuts, lock washers, and flat washers that secure the phenolic contact sup port plate to the stringers. NOTE: When this plate is lowered, the series trip solenoid plunger will slide out. c. Loosen the stringers with pliers and remove. d. Install new members as required and reassemble. 10. Refer to figure 9, and reassemble the interrupter in the following order: a. Position stationary contact assemblies on top plates. Be sure to include the gasket between these parts. Note that stationary contact tubes are identical. Slide them into position on the eight bolts. b. Install slotted fiber plates in pairs to form six exhaust ports in each interrupter assembly. Exhaust ports open to the load side on the end phases, and to the source side on the center phase. c. Slip the fiber tubes over the four center bolts and push up through the slotted fiber plates. Figure 12 Checking for correct clearance. Reclosers below serial no. 2001. d. Match the guide bushing with the center hole of the bottom plate and position the plate. Replace the flat washers, lockwashers, and hex nuts. Be sure reinforcing bars are placed on the exhaust end. Then install the moving contacts on the plunger shaft. e. Check moving contact clearance. As shown in figure 12, measure from the top of the contact yoke to the bottom of the interrupter assembly. This space should range between 1/64 and 5/64" inch when the KA90R closing tool is turned clockwise against the stop. If the space should be adjusted, add or subtract one or more wash ers above the roll pin in the plunger shaft to obtain the correct measurement. Any washers not placed above the roll pin should be retained between the contact yoke and the elastic stop nut. ARC INTERRUPTER ASSEMBLY (Units Above Serial No. 2000) After the W recloser has operated through a complete duty cycle, the arc interrupter assembly should be completely dismantled and any worn parts replaced. 1. Using a 1/2-inch thin wall socket, remove the vibration-proof hex nut that secures the contact yoke to the lift rod. Gently tap contact arm to remove contacts from the lift rod. Figure 13 Removal of arc interrupter assembly. Reclosers above serial no. 2000 2. Remove the terminal bolt from the top of each stationary contact assembly. 3. Remove hex nuts, flat washers, and lock washers from bottom of interrupter assembly. Page 12 SHOP MAINTENANCE -CONT'D FIGURE 14 Components of an interrupter assembly. Reclosers above serial no. 2000. 4. Slide the arc interrupter assembly downward. Figure 14 shows the individual parts in the order of removal. 5. Examine the stationary contact segments to determine if arc erosion has spread to the load contact surfaces. If so, the contact segments only, or the entire stationary contact assembly should be replaced. 6. Insert a large screwdriver through the stationary contacts to engage the fillister screw slot. With a box wrench, loosen and remove the contact nut while the screwdriver is held securely in a vise. Remove contact arms, contact cup, and retaining washer, leaving the retaining ring which rests in a slot on the inside of the tube. Figure 15 shows a dismantled stationary contact assembly. 7. To reassemble the stationary contacts slip the contact retainer onto the fillister head cap screw and arrange the six contact segments around the screw and retainer. Each of the six teeth on the retainer should fit into a hole on a contact segment. Place the garter spring, contact springs, and spring spacers over the small end of the assembly in the following order: garter spring, spring spacer, contact spring, spring spacer, and contact spring. FIGURE 15 Stationary contact assembly components. Reclosers above serial no. 2000. Insert this assembly into the contact cup by twisting in clockwise. Then push the cup and contacts into the large end of the tube. Insert the retaining washer and contact nut from the opposite end. Use the screwdriver to hold the fillister head cap screw while the contact nut is tightened. 8. Replace fiber plates in the arc interruption assembly if necessary. Refer to periodic maintenance, page 6. 9. Examine the insulating support stringers for evidenc of tracking or moisture absorption. Failure of these members is rare, but if any show tracking, replace as follows: a. Disconnect the lead attached to the series trip solenoid coil tube. b. Remove the hex nuts, lock washers, and flat washers that secure the phenolic contact support plate to the stringers. NOTE: When this plate is lowered, the series trip solenoid plunger will slide out. c. Loosen the stringers with pliers and remove. d. Install new members as required and reassemble. S280-30-3, Page 13 10. Refer to figure 14 and reassemble the interrupter in the following order: a. Place the fiber plates in two stacks on top of the bottom plate, in the order shown in Figure 15. Make sure that the gasket is included. The exhaust por ts open to the outside of the assembly. b. Drop the long spacer tubes into the corner holes of the two stacks. The lower end of each spacer tube should be flush with the lower surface of the bottom plate. Place the short spacer tubes over the portion of the long spacer tubes which protrude from the stacks. c. Position the stationary contact assemblies on top of the two stacks. d. Place the assembly in position on the contact frame and secure it with the eight mounting bolts. Reconnect the leads to the contact nuts. e. Install the moving contacts on the lift rod. CLOSING SOLENOID Very little maintenance should be required for the closing solenoid. It may be necessary to replace the solenoid coil if the recloser is to be operated at another voltage. Proceed as follows: SERIES TRIP SOLENIOD (Reclosers Below Serial No. 2001) Series trip solenoids can be equipped with either of two types of coils. Standard coils, contained completely within the solenoid frame, are used to achieve tripping at about 200 percent of full-load rating. Alternate coils, with one-half turn outside the solenoid frame, are used to achieve tripping at about 140 percent of full load rating. The same basic procedure is used to dismantle either solenoid. Disassemble as follows: 1. Remove cotter pin, and slide out pin and spacer that connect the insulated operating links, figure 16, and the solenoid plunger. 2. Loosen bolt indicated by arrow in figure 16, and remove hex nut that secures the connecting bar to the coil terminal. 3. Remove bolt that secures leads to one terminal of the trip coil. 4. Lift out solenoid plunger, terminal bolt, guide clips, and guide channels. Swing connecting bar aside and slide coil out. An exploded view of the trip solenoid is given in figure 17. Wipe off any carbon deposits with a clean, lint-free cloth. Replace any damaged parts. 1. Disconnect the two leads where they connect to the contactor assembly. 2. Remove four cap screws on the bottom of the solenoid frame and lower the coil and base plate. The coil can now be removed. 3. Examine the insulating support stringers for evidence of tracking or moisture absorption. Replace any defective members as follows: a. Remove the hex nuts, lockwashers, and flat washers that secure the solenoid frame to the stringers. b. Lower the solenoid frame slowly to avoid damaging the pump piston, lockout piston, and fast reset plunger when they swing free. c. Loosen the stringers with pliers; remove and replace as required. 4. Reassemble the closing solenoid by reversing the procedure. Be sure to use a new gasket between the coil and solenoid base plate. Also see that solenoid leads clear insulating stringers and the solenoid frame by at least 1/2 inch. Figure 16 Series trip solenoid Reclosers below serial no. 2001 Page 14 SHOP MAINTENANCE - CONT'D FIGURE 17 Exploded view of series trip solenoid. Reclosers below serial no. 2001 Reassemble solenoid as follows: 1. Place lower insulation plate in position, and insert terminal bolt. 2. Position the upper insulating plate on top of the coil as shown in figure 18a, and slide the coil back in place. Then push the insulating plate into position. Figure 18b illustrates how the alternate type trip coils are installed. FIGURE 18b 3. Replace in order, guide channels, guide clips, and plunger. Connect plunger to operating links. Secure connecting bar and tighten the bolt on the other end of the bar. Reclosers now being produced have bushings under the guide clip screws to prevent overtightening. 4. Bolt leads to the trip coil terminal. Be sure leads are formed so that they clear any insulating stringer or grounded part by at least 1/2 inch. SERIES TRIP SOLENIOD (Reclosers Above Serial No. 2000) Two coil kits are furnished for replacements to change recloser minimum trip ratings. Two coils in one kit are for substitutions in Phase A and Phase B interrupters. The separate one-coil kit for Phase C, the interrupter furthest away from the sleethood, has a coil with an opposite wind because of its different position on the interrupter. FIGURE 18a Series-trip solenoids can be equipped with either standard coils or an alternate coil. Standard coils are used to achieve tripping at approximately 200 percent of fullload rating. Alternate 400X and 560X coils are used to achieve tripping at approximately 140 percent of fullload rating. The same basic procedure is used to dismantle either solenoid. S280-30-3, Page 15 FIGURE 20 Solenoid disassembly. Reclosers above serial no. 2000 Solenoid Replacement: Check upper coil washer before replacing coils. For coils 280 amperes and below, the upper and lower coil washers are identical. For the 400 and 560 ampere coils a washer with a larger center slot (1-17/32” long instead of 1-7/32”) is substituted for the upper washer. The bottom washer remains the same for all coils. FIGURE 19 Series trip solenoid disassambly points. Reclosers above serial no. 2000 Solenoid Disassembly: 1. Remove cotter pin and slide out groove pin that connects the insulated operating links and the solenoid plunger, figure 19. 2. Remove the terminal bolt that fastens both the bushing lead and the outer coil terminal to the support bracket, figure 19. 3. Remove the cap screw that fastens both the terminal strap and the fiber end of the support bracket to the contact nut of the generator contact tube. 1. Place the lower insulation washer in position. (See figure 21. Pass the upper insulation washer over the terminal strap and position it on top of the coil as shown in figure 20. Push the coil into the solenoid frame and slide the upper washer into its normal position. Replace in order the guide channels, guide clips and plunger. 2. Place the solenoid assembly back on the mounting board and secure it with the two frame mounting bolts. 3. Connect the operating links to the plunger with the groove pin and replace the cotter pin. 4. A separate sleeve is provided with each coil to insulate the outer coil terminal from the frame. Slide sleeve over this outer coil as illustrated. 5. Connect the terminals to the contact tube and the bushing lead to complete reassembly. 4. Remove the two frame mounting bolts that secure the solenoid frame to the mounting board and lift the entire solenoid assembly off the mounting board. 5. Lift out the solenoid plunger, guide clips, and guide channels. Slide the upper insulation washer as far as it will go in the direction of the terminal strap. Lift the coil slightly and pull it out of the solenoid frame, figure 20. Wipe off any carbon deposits on these parts with a clean lint-free cloth. Replace any damaged parts at this time. FIGURE 21 Placement of lower insulation washer. Reclosers above serial no. 2000 Page 16 SHOP MAINTENANCE - CONT'D. CLOSING SOLENOID CONTACTOR If the double-break contacts of the closing solenoid contactor need replacement, the entire closing solenoid contactor should be replaced. Proceed as follows: 1. Disconnect closing solenoid and fuse leads, figure 22. 2. Remove two “C” rings to release pin that connects the operating link to the toggle mechanism. 3. Remove the three hex-head cap screws (not shown) that secure contactor to the frame. These are located on the underside of the frame. Contactor is now free to be removed. 4. Replace the contactor by reversing this procedure. The improved type toggle mechanism, shown here provides under-voltage protection for the closing solenoid. This mechanism opens the closing solenoid contactor when the solenoid plunger has only partially completed its stroke. Thus, when low voltage conditions exist, the plunger will be unable to complete a closing stroke. After a series of partial strokes, the lockout piston will be advanced enough to cause the recloser to lock open. The improved toggle is provided on units numbered 219 and higher, plus 195, 196, 198, 200, 201, 206, 207, 208 and 217. FIGURE 22 Changing closing solenoid contactor. 5. Be sure closing solenoid and fuse leads clear insulating stringers or grounded parts by at least 1/2 inch. CAUTION: Fuse leads must be connected to upper terminals of the contactor. HYDRAULIC PUMP AND LOCKOUT PISTON If the insulating oil has become dirty because of infrequent oil changes, removal of the pump and lockout piston for cleaning may be advisable. 1. Remove the two hex-head cap screws with a 7/16inch open-end or socket wrench. 2. Lift the mechanism housing as shown in figure 23. Both pistons and the fast reset valve rod will slide out. 3. Wipe out any carbon deposits with a clean, lintfree cloth and rinse the unit in new oil. See that the ball check valve in the bottom of the lockout piston cylinder and the ball check valve in solenoid frame is clean and free to operate. If it is necessary to replace the hydraulic pump piston for any reason, mark its position relative to the operating link. Note how the piston is restrained from rotation by a small indentation. FIGURE 23 Removing hydraulic pump and lockout mechanism. 4. Thread the new outer piston shell on the pump piston and adjust to the position marked on the operating link in step 3. Test for correct operation before staking the outer shell to the piston. S280-30-3, Page 17 NOTE: Removal of the head casting is necessary before this test can be performed. This procedure is required to observe the lockout bar. See page 16 for head removal instructions. To test the hydraulic mechanism for correct operation: Lower the unit into oil until the pump is covered completely. operate the pump manually a few times to remove any trapped air. Allow the lockout piston to fully reset. Now manually trip and close the recloser and observe the advance of the lockout bar. After the next-to-last trip operation has occurred, one end of the lockout bar should touch the control lever trip latch. 5. If increased lockout-bar-travel is needed, unscrew the outer piston shell to increase the effective length of the piston. To decrease lockout-bar-travel, screw the shell farther onto the piston. Adjust in one-half turn increments and repeat the test described in step 4 until proper operating performance is achieved. When the adjustment is completed set the new piston shell with a small punch. TIME-DELAY UNITS Maintenance of the time-delay units generally will be confined to an inspection of fluid level. Some loss of fluid level is normal, so this inspection should be made each time periodic maintenance is performed. To check the fluid level remove the filler plug located on the side of the unit for Type W reclosers under serial number 795. For Type W reclosers above serial number 794, remove the socket-head filler plug located on the side of the brass adjusting block. A special kit, catalog number KA806R2, is available to restore fluid level. This kit contains an eye dropper and two ounces of the special time-delay unit fluid (HFA—Hydraulic Fluid, Aircraft). Add enough fluid to bring the level to the filler plug hole. Be sure to replace the filler plug. FIGURE 24 Time-delay unit for Type W reclosers below serial no. 795. CAUTION: Avoid introducing any dirt, metal, or lint in the unit. Plugging of the orifice by foreign materials will cause erratic time-delay action. CLOSING SOLENOID FUSE To replace a blown closing solenoid fuse, simply disconnect the long lead at the closing solenoid contactor, the short lead at the fuse end, and loosen the mounting bolt. Slide the fuse out and install a new one. A tag attached to each closing solenoid coil shows the color band coding and catalog number of the correct fuse to protect the coil. Table I also shows this information. Be sure the fuse leads clear any grounded parts or the insulating stringers by 1/2 inch. FIGURE 23 Time-delay unit for Type W recloser above serial no. 794 Page 18 SHOP MAINTENANCE - CONT'D. REMOVAL OF HEAD CASTING BUSHINGS Access to the operating mechanism located in the main frame is achieved by removing the head casting. Proceed as follows: Maintenance of bushings is generally limited to an occasional cleaning. If a bushing should become cracked or broken, replace as follows (refer to figure 26). 1. Remove hex nut, lock washer, and flat washers on the lower end of the bushing to release the six straps. 2. Remove the three hex-head cap screws that secure the bushing clamps. Lift the bushing assembly up through the head casting. 3. An aluminum clamping ring cushions the pressure between the bushing and bushing clamps. The ring can be reused if it is in good condition. Twist the ring to slip it off the bushing. 1. Disconnect all bushing leads at the lower end of the bushings. Also disconnect any accessories, such as the ground trip solenoid, at their terminals. 2. Disengage the control lever and the contact position indicator by pushing the spring-loaded couplers, figure 27, inward. Turn the couplers to lock them in the disengaged position. 3. Disconnect the non reclosing control lever by removing the “E” ring indicated in figure 27 and separating the two connecting links. 4. The bushing assembly can be completely replaced, or new porcelain only may be installed. If new porcelain is used, unscrew the bushing terminal and draw the bushing lead rod out the lower end of the porcelain. Insert the rod in the new porcelain and replace the bushing terminal. Use a new terminal gasket. 5. Replace the bushing assembly, using a new gasket between the bushing and the head casting. CAUTION: When reconnecting bushings, take care to position flexible leads at least 1/2 inch from any vertical insulating support stringer, grounded part, or the contact plunger rod in each phase. On reclosers equipped with a ground-trip solenoid, also be sure one center phase lead clears the solenoid frame by 1/2 inch! FIGURE 27 Control lever disconnection prior to removing head casting. 4. If an auxiliary switch accessory is mounted on the recloser head casting, remove the “E” ring and washer, figure 28, to allow disconnection of the operating lever. 5. Remove the six 1/2-inch x 4-1/2-inch socket-head bolts that secure the frame to the head casting. Be sure the recloser mechanism is supported from below before these bolts are removed. Six tubular spacers will be released when the head is lifted. 6. To reassemble, carefully lower head casting in place with the tubular spacers mounted on the six lugs. Start the six 1/2-inch bolts and tighten evenly to avoid any binding of the mechanism. 7. Engage the contact indicator and manual operating lever. Reconnect the non-reclosing lever and, if used, the auxiliary switch. FIGURE 26 Bushing replacement. 8. Reconnect bushing leads and any accessory devices.

RATING CHANGES RATED CURRENT The Type W recloser’s continuous current rating can be easily changed by installing new coils in the series trip solenoids. Coils rated 100, 140, 160, 185, 225, 280, 400, or 560 amperes are available. Tripping occurs at about 200% of full load rating when the recloser is equipped with standard trip coils, or about 140% of full load rating when alternate coils (400X and 560X) are furnished. Refer to series trip solenoid sections for method of changing coils. P H A S E . TO - P H A S E VOLTAGE Closing solenoid coils are available for eight* voltage ranges from 2.4 to 14.4 kv. Refer to page 11 for the method of changing closing solenoid coils. * Solenoids rated 125 and 250 volts dc are also available. Contact factory for furthur information. When the closing solenoid coil is changed, the protective fuses may also have to be changed. Two fuses are shipped with each replacement coil. Table I shows the correct size fuse to use with different ratings of coils. Figure 29 shows the fuse time-current characteristics. ADJUSTMENTS See “Installation Manual, M-E Type R and Type W oil Circuit Reclosers,” for information about adjustments of operations to lockout, time-delay characteristics, reclosing time, number of fast operations, ground trip solenoid, or the TW current transformer. Refer to series trip solenoid section for the method of changing coils. CONTROL LEVER OVER-TRAVEL ADJUSTMENT To check for proper adjustment of the control lever, observe the following procedure: 1. Remove the sleet hood cover to expose the control lever. 2. From the “OPEN” position, slowly push the control lever toward the “CLOSED” position. As the lever is pushed up, latching of the recloser will be felt. At this point, dimension “a” should be 1/4-inch. To adjust, observe the following procedure: 1. With diagonal cutters, open the “C” ring and remove it. 2. Slide control lever off the shaft. 3. Rotate the control lever clockwise to reduce dimension “a” or counterclockwise to increase dimension “a”. 4. Reassemble by reversing the procedure when the correct clearance has been set.
