reclosers types w, wv27

1DESCRIPTIONKyle W-group three-phase automatic,circuit reclosers provide reliable, eco-nomical overcurrent protection for dis-tribution circuits rated through 38 kV.Compact and self-contained in opera-tions, these reclosers can be easilyinstalled on poles and in substations.Employing the service-proven hydrauliccontrol, the W-group reclosers can bereadily coordinated with circuit break-ers, sectionalizers, fuses, and otherreclosers on the distribution system.Kyle reclosers in a distribution systemprotection scheme offer significant useradvantages. Their broad applicationcapabilities permit the user to selectexactly the right recloser for the pro-tection required. When needed, appli-cation expertise, backed by world-wide recloser application experience,is readily available. Knowledgeabledesign capability, based on over 60solid years of recloser manufacturingexperience, is the backbone of ourdependable reclosers. Progressivedevelopment programs using the lat-est technologies have resulted in themodern, efficient Kyle reclosers. W-group reclosers, like all Kylereclosers, are designed and built inaccordance with ANSI C37.60. Six distinct typesW, WV27, WV38X,VW, VWV27, and VWV38X withinthe W-group offer a broad range ofvoltage, continuous current, and inter-rupting ratings. Accessories permittailoring a recloser to specific applica-tion requirements. Mounting equip-ment for both pole and substationfacilitates installing a recloser pre-cisely where system requirementsdemand its protection.

BASIC RATINGSW and VW reclosers protect systemsrated 2.4 through 14.4 kV; WV27 andVWV27 reclosers protect systemsrated through 24.9 kV; and WV38Xand VWV38X reclosers protect sys-tems rated through 34.5 kV. Table 1summarizes the ratings of the W-group reclosers. For basic ratings andapplication information for all Kylereclosers, see Catalog Section 280-05.

BASIC CHARACTERISTICSW-group reclosers are hydraulicallycontrolled protective devices in whichtripping is initiated by a series trip coilthat releases the stored-energy tripmechanism when an overcurrentoccurs. Current-carrying and inter-rupting capacities depend on the rat-ing of the recloser series trip coil.Minimum-trip current is 200% of thecoil rating, except X coil ratings whichinitiate tripping at approximately 140%.A closing solenoid supplies the ener-gy for contact closing and also storesenergy in the trip mechanism. High-voltage closing solenoids are con-nected to the system on the sourceside of the recloser. Solenoid phase-to-phase voltage rating is based onthe system operating voltage. Low-voltage closing solenoids can beused if auxiliary voltage is supplied tothe recloser.Dual timecurrent characteristics per-mit coordinating W-group recloserswith other protective devices on a dis-tribution system. Fast-curve trip oper-ations are followed by trip operationson a delayed curve. A choice of fourdelayed characteristics allows flexibil-ity in system coordination. Groundtripping is available as an accessory.A variety of operating, indicating, andservice accessories extends a W-group reclosers normal flexibilityeven further.Oil InterruptionW, WV27, and WV38X reclosers useoil as the arc-interrupting medium.Movable bridge-type contacts providetwo breaks in series on each phase.Separate self-generating interrupterchambers at each of the two breakseffectively interrupt all currents fromminimum load to rated maximum fault.

Vacuum InterruptionVW, VWV27, and VWV38X reclosersuse vacuum as the arc-interruptingmedium. Vacuum interruption notonly means long contact life, it alsooffers considerably longer duty cyclesthan oil interruption. A single breakon each phase is accomplished byseparating contacts inside the vacu-um interrupter. All arcing is containedwithin the vacuum envelope. Low-energy arc interruption in a vacuumresults in far less shock and demon-stration than interruption in oil, thusextending the vacuum recloser mech-anism life. Because interruption with-in the vacuum envelope does not addcontaminants to the insulating oil,recloser maintenance is minimizedand intervals between oil changescan generally be extended.

Surge ProtectionBest operating results are achieved ifreclosers are protected with surgearresters. On line applications,arrester protection is recommendedon both sides of the recloser. (If pro-tection is on one side only, it shouldbe on the source side.) In substations,arresters should be on the load side.Cooper Power Systems distribution-class arresters provide excellent pro-tection and are available with mount-ing brackets to fit Kyle reclosers; seeService Information S280-85-7.

Basic Recloser DesignKyle three-phase W-group reclosersare designed to protect circuits onsystems operating through 34.5 kV.With the ratings available and theability of these reclosers to coordinatewith other protective equipment,including lower-rated reclosers, theycan be applied in a variety of schemes.The range of protection can beextended by a ground-trip accessory,which provides protection againstground-fault currents that are lessthan the minimum-trip value of theseries coils. Flexibility of application isgreatly enhanced by accessories thatenable remote control of the recloser.

Closing energy is supplied by a closingsolenoid that simultaneously chargesthe opening springs in preparation fora tripping operation. Fault currentsare sensed by trip coils (connected inseries with the recloser contacts) thatinitiate the tripping operation byreleasing the opening springs.Series tripping provides simple andreliable operation because the energyto initiate the tripping operation istaken directly from the line. W-groupreclosers are self-contained: theyrequire no external control or controlpower source.The hydraulic control incorporatesseparate elements to govern time-delayoperations and regulate the number

of operations to lockout. The W-groupbasic design has been proven bymore than 50 years of field service.ConstructionLike all the other Kyle reclosers, theW-group reclosers are designed forlong service life with little mainte-nance. Heads are aluminum castings.Tanks are heavy-gage steel, finishedwith light gray polyester powder paint(ASA70). An o-ring gasket confined ina groove, for controlled compression,assures an oil-tight seal between thehead and the tank. A 1/2-inch brassoil-sampling and drain valve near thebottom of the tank is standard.

The entire internal mechanism is sus-pended from the head casting so thatthe mechanism and the head assem-bly can be removed from the tank asa unit. Reclosers are mounted bybrackets that can be attached to thehead casting. This permits easyaccess to the contacts and the mech-anism in the field by lowering the tankwith a wire-rope winch, which is avail-able as an accessory.The insulating supports from whichthe three interrupters are suspendedare filament-wound glass epoxy forhigh electrical and mechanicalstrength and moisture resistance.

Operation

Series Trip CoilFault current in the W-group issensed by the three trip coils that areconnected in series with the reclosercontacts and can carry line current upto their rating. Coils of applicableratings are interchangeable amongthe W-group reclosers. Continuouscurrent and minimum trip ratings canbe changed by replacing the coils.When fault current in excess of theminimum trip ratings flows on one ormore phases, the trip solenoidplunger, which is normally held at restby the mechanism, is drawn into thecoil by the magnetic effect generatedby the fault current.

Near the end of the downward stroke,a linkage connected to the tripplunger trips a latch that releases thecharged opening springs and therecloser contacts are opened.The series trip coil is surge-protectedby a shunting bypass gap on recloserswith trip coils rated below 100 A.Independent fault detection on eachphase is provided by separate tripcoils. A common bar trips all threephases, preventing single-phase sup-ply to three-phase loads. A trip coilcarrying a higher fault current willoverride and cause faster trippingthan a phase experiencing a lowerfault current.

Closing SolenoidClosing energyas well as the energyto charge the opening springs in theW-group reclosersis supplied by ahigh-voltage closing solenoid, whichis connected phase-to-phase andenergized through a contactor. Whenthe recloser contacts are closed, thesolenoid plunger is latched in thedown position. This latch is trippedsimultaneously with the release of theopening springs and the solenoidplunger moves upward. A timing ori-fice in the bottom of the solenoid-plunger cylinder regulates the rate atwhich upward movement can takeplace as oil is drawn into the cylinder.As the solenoid plunger reaches thetop of its stroke, the high-voltage linecontactor energizes the closingsolenoid, pulling the plunger down.The closing solenoid contactoropens, de-energizing the coil, and,through the mechanical linkage, themain contact-operating rods aresimultaneously moved upward toclose the contacts. At the same time,the opening springs are charged inpreparation for a tripping operation.W, WV27, VW, and VWV27recloserswhich are rated through24.9 kVare equipped with a high-voltage closing solenoid contactorwith two breaks in series. The higherrated reclosersWV38X andVWV38Xare equipped with a con-tactor with four breaks in series.Control of the upward travel of theplunger regulates reclosing time.Normal reclosing time for the W-group reclosers is two seconds. Thefirst reclosing operation in the pro-grammed sequence can be 30 or 45cycles when the dual-reclosingaccessory is used.

Hydraulic Control SystemOperationThe number and sequence of opera-tions to lockout and the time-delayoperations are controlled by two sep-arate hydraulic mechanisms whichare mechanically linked.Pump-and-Lockout-PistonAssemblyThe hydraulic pump, associated cam,and linkages regulate the number offast and delayed operations, count theoperations to lockout, and, after a presetnumber of operations, initiate lockout.The hydraulic pump (Figure 7) islinked to the closing solenoid plungerand pushed downward with eachreturn operation of the plunger. Withits downward stroke, the pump forcesa measured amount of fluid under thelockout piston, causing it to rise onestep. Ball-type check valves retain thecharge. When the closing solenoid isenergized, the recloser contacts closeand the pump returns to its normalposition.The lockout piston is linked to thesequence selector cam (Figure 8)and the lockout bar. Upward move-ment of the lockout piston causes thecam to rotate counterclockwise andthe lockout bar to advance one step.The number of fast operations arepreset on the cam.

After these operations, the cam edgeengages the roller and pushes it tothe right. A mechanism arm attachedto the roller engages the time-delaymechanism on each phase.Subsequent operations are thendelayed.When the lockout bar completes itstravel, it trips the lockout latchthrough another set of linkages andsprings lock the recloser contactsopen. The reset rod and valve (Figure7) are raised, releasing hydraulic fluid

from beneath the lockout piston sothat it resets quickly. The entire pumpand sequencing mechanism are nowready for the next full sequence ofoperations.For temporary faults that are clearedbefore the recloser mechanismreaches lockout, the lockout pistonresettles gradually (at a rate ofapproximately 90 seconds per opera-tion at 25C) to reset the reclosermechanism.

Operating SettingsThe required sequence of fast anddelayed operations and the requirednumber of operations to lockout arefactory set per customer specification.Either or both settings are easilychanged in the field; only a partialuntanking of the recloser is necessaryand no special tools are needed.

Internal settings for the number ofoperations to lockout permit therecloser to be programmed for two,three, or four trip operations to lock-out. Programming for one operationto lockout is done with the externalnon-reclosing handle located underthe sleet hood. The internal setting iseasily changed by moving the hori-zontal lockout bar (Figure 9) to indexthe lockout-setting pin in the requirednotch.Moving the external non-reclosinghandle down activates the non-reclosing feature (one operation tolockout); this overrides the internalsetting but does not change it physi-cally. When the non-reclosing featureis deactivated (handle moved up), thenumber of operations to lockoutautomatically reverts to the internalsetting, providing complete flexibilityfor testing or service without disturb-ing the programmed operations-to-lockout setting.

The timing of recloser trip operationscan be fast (which includes no inten-tional time delay), delayed (which fol-lows one of four slower timecurrentcharacteristics), or a sequence of fastfollowed by delayed. The recloser mechanism is pro-grammed simply by setting the num-ber of fast operations required ineach sequence of operations to lock-out, by indexing a notched cam to therequired number (Figure 8). It is easily changed by lifting the flatspring tab away from the cam androtating the cam until the desirednumber of fast operations is indicat-ed. The setting for the number of fastoperations determines the number ofdelayed operations in the sequence;for example, if four operations to lock-out are selected and the cam isadjusted for two fast operations, thesequence will be two fast operationsfollowed by two delayed.

Time-Delay MechanismDelayed operations in W-groupreclosers are established by thehydraulic time-delay mechanism oneach phase. The time-delay mecha-nism is engaged with timecurrentcharacteristic. The selected curve isestablished by the time of engage-ment of the time-delay mechanism.For the B and D curves, approximate-ly half of the stroke is unimpeded,then the trip coil linkage engages thetime-delay mechanism and theremainder of the stroke is impeded,establishing the desired curve. Withthe slower (C and E) curves, the timeof engagement is earlier.The time-delay mechanism permits achoice of two characteristics: B and Cor D and E. The time-delay curveswill be set at the factory as specified.Adjustment from one characteristic tothe other is made by indexing athumbscrew-and-bracket arrange-ment on the time-delay mechanism tochange the curve by changing thetime of engagement (Figure 10).

Figure 10.Changing timecurrent characteristics to the alternate curve is accom-plished by loosening the thumbscrew and indexing the adjustmentbracket to the proper hole.

010060KMFigure 9.The internal setting for the num-ber of operations to lockout (two,three, or four) is achieved by posi-tioning the lockout-setting pin inone of three notches in the lock-out bar. This setting is easilychanged in the field.

Established DelayOperationsOperation of the time-delay mecha-nism is initiated by the integratingmechanism. As the indexing cam(Figure 8) is rotated counterclockwiseby the upward movement of the lock-out piston, it engages a roller assem-bly, causing the solenoid linkageengagement arm to pivot clockwise,placing its hook above the pin on thetime-delay arm. When an overcurrentoccurs and the engagement armmoves downward with the trip coillinkage, the hook engages the pin onthe time-delay arm and the time-delaymechanism impedes the remainder ofthe stroke.

OperationThe hydraulic time-delay mechanismpiston is pulled downward by the tripcoil linkage. A floating plate (retainedby an open basket) at the bottom ofthe hollow piston functions as a one-way valve on the downstroke, sealingthe bottom of the piston.On low-current operations, displacedoil is forced around the grooved pin inthe low-current valve and is allowedto return to the space above the pis-ton. When a higher current fault isinterrupted, increased oil pressureraises the springloaded valve so thatoil flows through both valves and thetripping operation is accelerated pro-portionately.The hydraulic time-delay mechanismhas no effect on contact-openingspeedit only delays the moment atwhich the opening springs arereleased.

Interrupter Construction

Oil Interrupters Fast arc interruption (down to 2 1/2cycles clearing) is achieved bybridge-type contacts that provide twocurrent breaks in series per phase.The bayonet-type moving contactsare silver-plated tungsten alloy forerosion resistance and good conduc-tance. The stationary contact assem-blies are tulip-type clusters of silver-plated contact fingers held togetherby garter springs. The contacts areself-cleaned by the opening and clos-ing wiping action.

Each current break is provided with aself-generating arc interrupter struc-ture which includes a series of ventedchambers. As the contacts open, thearc generates gas pressure in theupper chamber that blasts oil acrossthe arc and out through the vents. Asa result, arc extinction is fast and arcenergy levels do not increase as fastat the higher fault-current levels.

Vacuum InterruptersVacuum interrupters provide fast, low-energy arc interruption with long con-tact and interrupter life, low mechani-cal stress, and maximum operatingsafety. With arc interruption takingplace in a vacuum, contact and inter-rupter life are several times greaterthan with interruption in oil, and inter-rupter maintenance is virtually elimi-nated. Because of the shorter contactstroke, mechanical stress and wearon the mechanism is substantiallyreduced.Kyle vacuum interrupters aredesigned with a metal and ceramichousing for maximum strength andlong-term vacuum integrity. The high-alumina ceramic has more than fivetimes the strength of glass, permits ahigher processing temperature todevelop maximum purity of theassembly, and is impervious to heliumpenetration to sustain the vacuumlevel. Metal end-closures and the arc-ing chambers are of high-purity alloyto minimize contamination.Enclosed in the interrupter is a station-ary and a moving contact assembly.The moving contact has a travel ofapproximately one-half inch, its shaftpassing through a flexible bellowswhich maintains vacuum integrity.Contacts are made of a special non-welding alloy.

Because the smallest amount of inter-nal contamination can significantlyshorten the life of a vacuum inter-rupter, a clean-room facility is usedfor interrupter production. Specialcare is taken to avoid even minutecontamination from any source,whether it be dust particles, machin-ing oils, or human body salts.

ACCESSORIESW-group reclosers can be supple-mented with a number of accessoriesto provide added application flexibility.Some accessories modify the normaloperating functions while othersincrease operating versatility; still oth-ers provide indicating functions. Foreach accessory installed on a particu-lar recloser, a data plate is mountedon the sleet hood of the recloser.Where required, accessory leads arebrought into the recloser tank througha junction box mounted on the headcasting.Bushing-Type, Multi-RatioCurrent TransformersMulti-ratio current transformers foroperating meters or separate relayscan be mounted on load-side bushings2, 4, and 6 or the source-side bush-ings 1, 3, and 5 (Figure 13). Thesecurrent transformers have only oneprimary turnthe bushing rod. Theyare available with secondary wind-ings that provide primary/secondary-current ratios of either 600:5 or1200:5. Different ratios can beobtained by connection to appropriatetaps on their secondary windings.Ratios obtainable from 600:5 and1200:5 transformers are shown inTable 6.

Hydraulic Ground-TripAccessory

If the rated minimum zero-sequence(ground) current is exceeded, thehydraulic ground-trip mechanismanoil-dashpot-type solenoid connectedto paralleled BCT secondariestripsthe recloser. The hydraulic ground-trip mechanism accessory enablesthe recloser to protect against ground-fault currents lower than the reclosersminimum phase-trip setting. For cur-rents above the minimum phase-tripsetting, recloser opening is governedby either the phase-trip series coil orthe ground-trip coil, whichever isfaster. Refer to Reference DataR280-91-7 for available delay curves.The ground trip coil is operated fromthe bushing-type, multi-ratio currenttransformers mounted on the source-side bushings (1, 3, and 5) to producethe minimum ground-trip currentsshown in Table 7. The current trans-formers must be ordered separately.

Electronic Ground-TripAccessorySelf-contained, independent, sensitiveground-fault tripping is also availablewith an electronically controlledground-trip accessory that includesthe following:

Fifteen fault-timing characteristicsincluding inverse and definite-timecurves, or plug-in modules thatare easily field changed.

Dual-timing capability. Twelve minimum-trip levels, from5 to 400 A.

Line powered; completely self-contained.

Precharging coil for consistenttimings even when reclosing on apermanent fault.

Fault-timing characteristics and timingoperations are independent and sep-arate from the reclosers phase faulttiming and TCCs. Counting to lockoutis integrated with phase operations.The dual-timing feature enables coor-dination with other protective appara-tus on the system.Accessory control circuits are pow-ered from the line through two currenttransformers mounted under thehead casting on source-side bush-ings (Figure 15). Five amperes of linecurrent is all that is required to main-tain circuit charge and supply the tripoperation.Zero-sequence (ground) current issensed by three parallel-connectedcurrent-sensing transformers mount-ed beneath the head casting on theload-side bushings. When the groundcurrent exceeds the selected minimum-trip level, the control circuits actuatethe magnetic tripper to trip the reclos-er. Ground overcurrent timing isaccording to the timecurrent charac-teristics programmed with plug-inmodules on the accessory circuitboard.When the recloser automaticallyrecloses or is otherwise closed byelectrical operation of its closingsolenoid, an initial arming featureinstantly charges the accessory con-trol circuits. This enables the ground-trip accessory to respond immediate-ly, according to its programmedtimecurrent characteristic, should aground fault be present.

If the system downline from therecloser is energized by other thanelectrical operation of the recloser(such as the closing of an uplinerecloser or breaker), control-circuitarming time must be added to thepublished timecurrent characteristicfor proper TCC coordination. Furtherinformation that can be used in antici-pating such circumstances is foundwith the published timecurrent char-acteristics on this accessory; refer toCooper Power Systems ReferenceData R280-91-12.

Ground-Trip BlockingSwitchA ground-trip blocking switch can beprovided for either ground-trip acces-sory. The hotstick-operated blockingswitch (Figure 16) is normally mount-ed on the recloser. The manual lever-operated blocking switch (Figure 18)is for remote mounting.

Remote TripWhen energized from an externalsource, the remote trip accessory(Figure 18) trips the recloser, just aswhen the series trip coil operates.Normal automatic reclosing follows.Reclosing will occur even if thesolenoid remains energized. Shouldthis condition occur, the recloser willoperate to lockout. The remote tripaccessory leads are brought out ofthe recloser tank through a separatelyspecified accessory junction box.Electrical ratings are shown in Table 8.Note: The remote trip accessory cannot

be installed on a recloser equippedwith a ground-trip accessory(hydraulic or electronic) since bothoccupy the same space and oper-ate the same trip-lever mechanism.

Low-Voltage DC ClosingBy specifying a dc-closing solenoidfrom Table 17 and this accessory, therecloser can be closed by an exter-nally controlled low-voltage dc powersource rather than from the primaryhigh-voltage source. A separatelyspecified accessory junction box withinput terminal block is also required.Low voltage is especially desirable inloop and load-transfer schemeswhere the recloser can be operatedregardless of which side of the unit isenergized. Current requirements fordc closing are 55 A at 125 Vdc or 58 Aat 48 Vdc.Low-Voltage AC ClosingWith the addition of a modified clos-ing contactor equipped with a full-wave diode bridge (Figure 19), the dcclosing solenoid can be operatedfrom a low-voltage ac source. Currentrequirements for ac closing are 51 Aat 120 Vac or 34 A at 240 Vac.

Auxiliary SwitchRemote indication of recloser contactposition or switching of other devicescan be accomplished with an auxiliaryswitch. A three-stage switch is mount-ed on the recloser (Figure 20). Eachstage has two independent contactsa and/or b. When the reclosers maincontacts are open, the a contacts arealso open and the b contacts areclosed. Table 10 shows the recloser/auxiliary switch contact relationship.Switch contacts are insulated for 600 Vand have a continuous current ratingof 10 A. The interrupting ratings ofthe auxiliary switch contacts areshown in Table 9.

Lockout-IndicatingSwitchA lockout-indicating switch assemblycan be added for remote indication ofrecloser lockout (Figure 21). Theswitch is particularly useful in load-transfer schemes.Consisting of two single-pole, double-throw switches in a weatherproofhousing, the assembly is actuated bythe reclosers manual operating lever.A threaded opening for a one-half inchIPS conduit or cable grip is provided.Electrical ratings of the lockout-indicatingswitch are shown in Table 11.

Remote LockoutThe remote lockout accessory(Figure 22) enables an external con-trol to trip the recloser and operatethe lockout mechanism. The remote lockout accessory leadsare brought out of the recloser tankthrough a separately specified acces-sory junction box with terminal block.Electrical ratings of the remote lock-out accessory are shown in Table 12.Note: To provide complete remote opera-

tion, the remote lockout accessoryis usually employed with theremote close accessory.

Remote CloseWhen energized from an externalsource, the remote close accessorycloses a locked-out recloser by man-ually pulling the operating handle tothe CLOSE position, actuating thehigh-voltage closing solenoid contac-tor to close the recloser. The externalcontrol circuit for this accessoryrequires a connection that includes acustomer-furnished, normally open,momentary contact switch wired inseries with the solenoid.Electrical ratings of the remote closeof locked-out recloser accessory areshown in Table 13.Note: When this accessory is added to a

recloser, the recloser cannot lock-out if the remote close accessoryis held energized.

Remote Block of ClosingThe remote block of closing accessoryenables remote control of closing(Figure 24). One type blocks closingwhen the solenoid is energized; theother blocks closing when the solenoidis de-energized.Electrical ratings of the remote blockof closing accessory are shown inTable 14.
