Switchgear installation resistant tointernal arc faults, with pressure relief

It is possible to install 8DJ secondary distribu-tion switchgear, which are resistant to internalarc faults and feature pressure relief, in e. g.– Compact substations– Substations with control aisles– Switchgear buildings

Covers for pressure relief outlets and ducts,expanded metal assemblies etc. do not con-stitute a part of the switchgear. They mustbe supplied by the customer.

Absorber system (option) for 8DJ10/8DJ20secondary distribution switchgear and8DH10 switchgear

For the use of maintenance-free andclimate-independent switchgear in oldersubstation buildings which do not featurearc-fault testing, the 8DJ20 switchgear canbe designed with modified pressure reliefsystems and absorbers.

The pressure absorber system is enclosedand maintenance-free.As a “special cooling system”, it reducesthe pressure-dependent and thermal effectsof arc faults in the switchgear vessel and thecable connection compartment, and thusprotects both people and buildings.

Switchgear withpressure absorber system

• Method of installation:– Wall-standing arrangement for

8DJ10, 8DJ20 and 8DH10 switchgear– Option: free-standing arrangement

for 8DH10 switchgear

• Feasibility:– 8DJ10 switchgear with a height of

1650 mm, up to 16 kA– 8DJ20 switchgear with a height of

1400 mm and 1760 mm, up to 16 kA– 8DH10 switchgear with a height of

1700 mm, up to 20 kA

Characteristics

• Switch positions:CLOSED – OPEN – EARTHED

• Designed as a multi-chamberswitch incorporating thefollowing functions

– Switch-disconnector and– Make-proof earthing switch

• Operation via gas-tightwelded bushing at the frontof the switchgear vessel

• Switching functions asgeneral purpose switch-

disconnector (Class E3)according to

– VDE 0670 Part 301– IEC 60 265-1– VDE 0670 Part 2/EN 60 129– IEC 62 271-102

Mode of operation

The switch shaft with themoving contact pieces rotatesinside the chamber containingthe fixed contact pieces.

Compression vanes, whichrotate in conjunction with theswitch shaft, divide the arcing

chamber into two subcham-bers each of which changes inconjunction with the rotation.

During the switching move-ment, the compression vanesgenerate a pressure differencebetween the subchambers.The SF6 gas flows through anozzle, causes a directionalblow-out of the breaking arcand quenches it rapidly.

Interlocking is not necessaryas the CLOSED and EARTHEDfunctions cannot be imple-mented simultaneously.

Closing operation

During closing operation, theswitch shaft with the moveablecontact blades moves from the“OPEN” to the “CLOSED”position.

The force of the spring-operatedmechanism ensures a highclosing speed and a reliableconnection of the main currentpath.

The good insulating propertiesof the SF6 gas delay striking ofthe arc to the arcing tips of thefixed contacts.

Opening operationDuring opening operation, theSF6 gas is compressed in thearcing chamber.

The compressed gas, whichflows from the nozzles of themoving contact blades, coolsdown the opening arc betweenthe contacts and safelyquenches it in a fewmilliseconds.

The isolating gap created byopening fulfills the conditionsapplicable to isolating gaps inaccordance with VDE 0670

Part 301 and Part 1000, andwith IEC 60 265-1 andIEC 60 694.

Due to the gas flow into thearcing chamber, which iscontrolled by the operatingmovement, both load currentsand minor no-load currents aresafely interrupted.

Earthing

“EARTHING” is implementedby moving the operating leverfrom the “OPEN” to the“EARTHED” position.

Operating mechanisms

Modules

Manual operating mechanism(detachable lever mechanism)

The three-position switch-disconnector is operated via arocker with metal bellows, whichis gas-tight and welded at theswitchgear vessel.

Spring-operated mechanism

The spring-operated mechanismis used for three-positionswitch-disconnectors in ring-main feeders (as ring-mainswitches).

The switching movements areperformed independently of the

operating speed.Spring-operated/stored-energymechanism

The spring-operated/stored-energy mechanism is used forthree-position switch-disconnec-tors in transformer feeders (astransformer switches).

The switching operations arethe same as for the spring-operated mechanism. Anenergy store mechanism isavailable for tripping with thehelp of a tripping HV HRC

fuse or via the shunt release.No additional charging proce-dure is required for the energystore mechanism. This energystore mechanism is alreadycharged by the switchingoperation from the “TRIPPED”position to the “OPEN” posi-tion. The precharged energystore mechanism also ensuresthat the switch-disconnector/ fuse combination can safelyswitch off all fault types duringclosing.

After tripping, a red bar appears

in the switch position indicator.

Operation of the operatingmechanism

• Standard: detachable levermechanism

• Option: rotary operatingmechanism for 8DJ20

• Option for detachable leverand rotary operating mecha-nisms: design according toVDEW recommendation –Association of German PowerStations – VDEW e.V.

HV HRC fuse assembly

Design• For switch-disconnector

panels

• HV HRC fuse links accordingto DIN 43 625 (main dimen-sions) with striker pin in“medium” version acc. toDIN VDE 0670 Part 4 / IEC 60 282

– as a short-circuit protectionbefore transformers

– with selectivity (dependingon correct selection) toupstream and downstreamconnected equipment

– single-pole insulation• Requirements according to

VDE 0670 Part 303 andIEC 60 420 fulfilled by com-bination of HV HRC fuseswith the three-positionswitch-disconnector

• Climate-independent andmaintenance-free, with fusebox made of cast resin

• Fuse assembly connected tothe three-position switch-disconnector via weldedbushings and connecting bars

• Location of the fuseassembly

– above the switchgear vesselfor 8DJ10, 8DJ20 and 8DH10switchgear

– beside the switchgear vesselfor 8DJ30 switchgear

• Fuse can only be replaced iffeeder is earthed

• Option:with shunt release

• Option:“Tripped indication” of thetransformer switch for

remote electrical indicationwith 1 NO contact

Modules

Mode of operation

In the event that a HV HRCfuse link has tripped, theswitch is tripped via anarticulation which is inte-grated into the cover ofthe fuse box (see figure).

In the event that the fusetripping fails, e.g. if thefuse has been insertedincorrectly, the fuse box isprotected by thermal pro-tection. The overpressuregenerated by overheatingtrips the switch via the sili-con diaphragm in the coverof the fuse box and via anarticulation. This breaks thecurrent before the fuse boxincurs irreparable damage.

The above thermal protectionworks independently of thetype and design of the HV HRCfuse used. Like the fuse itself itis maintenance-free and inde-pendent of any outside climaticeffects.

Furthermore, the SiemensHV HRC fuses release thestriker pin independently ofthe temperature and trip theswitch-disconnector as earlyas in the fuse overload range.Impermissible heating of thefuse box can be avoided in thisway.

Replacement of HV HRC fuselinks

• Isolating and earthing ofthe transformer feeder

• Subsequent manualreplacement of theHV HRC fuse link

Ready-for-service indicator

Characteristics• Self-monitoring; easy to read

• Independent of temperatureand pressure variations

• Independent of site altitude

• Only responds to changes ingas density

• Option: alarm switch“1 NO contact” for remoteelectrical indication

Mode of operation

For the ready-for-service indica-

tor, a gas-tight measurementbox is installed on the inside ofthe switchgear vessel.

A coupling magnet, which isfitted to the bottom end of themeasurement box, transmitsits position to an outside arma-ture through the stainless steelswitchgear vessel. This arma-ture moves the ready-for-ser-vice indicator of the switchgear.

While changes in the gasdensity during the loss of gas,which are decisive for theinsulating capacity, are dis-

played, temperature-depen-dent changes in the gaspressure are not. The gas inthe measurement box has thesame temperature as that inthe switchgear.

The temperature effect iscompensated via the samepressure change in both gasvolumes.

• The insulating capacity is veri-fied by testing the switchgearwith rated values of short-duration power-frequencywithstand voltage and light-ning impulse withstand volt-age according to VDE 0670Part 1000 or IEC 60 694 (see

adjacent table)• The rated values are referred

to sea level and to normalatmospheric conditions(1013 hPa, 20 °C, 11 g/m3

humidity in accordance withVDE 0111 and IEC 60 071)

• The insulating capacitydecreases with increasingaltitude but is not taken intoaccount by the standards andspecifications up to a sitealtitude of 1000 m

All of the parts housed inside

the switchgear vessel which aresubjected to high voltage areSF6-insulated against theearthed enclosure.

With a gas overpressure of500 hPa, this insulation permitsswitchgear installation at anydesired altitude above sealevel, without the insulatingcapacity being adverselyaffected. This also applies tothe cable connection whenusing plug-in sealing ends.

Insulating capacity forswitchgear with HV HRC fuses

When HV HRC fuses are used,the conductors are led out ofthe SF6 insulation through thebushing. For these connectionsin air, the rated values (ratedlightning impulse withstandvoltage, rated short-duration

power-frequency withstandvoltage) of the insulatingcapacity referred to normalatmospheric conditions(1013 hPa, 20 °C, 11 g/m3

humidity), hence to sea level,are in accordance withVDE 0111 and IEC 60 071.

As the altitude increases, theinsulating capacity of insulationin air decreases due to thedecreasing air density. Inaccordance with VDE and IEC,this decrease (r correctionfactor a = 0.9, see adjacent

diagram) is permitted up to ansite altitude of 1000 m.

For site altitudes over 1000 m,the standards do not provideany guidelines for the insula-tion rating. Instead, special reg-ulations apply to these alti-tudes.

Result:

According to the abovetable, switchgear for arated voltage of 24 kV is tobe selected.

* These standards are scheduledfor collation under IEC 62 271(switching devices and switchgear).

Resistance tointernal arc faults

Thanks to the single-poleenclosure of external modulesand the SF6 insulation of theswitching devices, the numberof potential faults in SF6-insu-lated switchgear for secondarydistribution systems is a merefraction of that typical of earlierswitchgear types, due to

• The absence of causes fordisturbances due to outsideinfluences such as

– Pollution layers– Humidity– Small animals and foreign

matter• Maloperations are practically

excluded due to the logicalpositioning of the operatingmechanism elements

• Short-circuit-proof earthing ofthe feeder by means of thethree-position switch-disconnector

In the event that an internalarc fault occurs at the cableconnection, the pressure isreleased downwards into thecable basement.

In the unlikely event of a faultwithin the switchgear vessel,the energy conversion in thecase of an internal arc fault isminor thanks to the SF6 insula-tion, i.e. approximately only 1 / 3compared to air. The escapinggases are discharged down-wards.

Pressure absorber system(option) for 8DJ10 and 8DJ20secondary distribution switch-gear and 8DH10 switchgear

For the use of maintenance-

free and climate-independentswitchgear in older substationbuildings without resistanceto internal arc faults, theswitchgear can be designedwith a modified pressure reliefsystem with absorber.

As a “special cooling system”,this maintenance-free pressureabsorber system reduces thepressure-dependent and ther-mal effects of internal arc faultsin switchgear vessels and ca-ble connection compartment,and thus protects people and

buildings.The enclosed switchgear issuitable for both wall and free-standing installation.

Climate and ambientconditions

The 8DJ/8DH switchgear isfully enclosed and insensitiveto climatic conditions.

• Climatic tests fulfilled in ac-cordance with IEC 60 932(report)

• All medium-voltage devicesare installed in a gas-tight,welded stainless steel hous-ing which is filled with SF6gas

• Live parts outside the switch-gear vessel are provided withsingle-pole enclosure

• At no point can creepagecurrents flow from high-voltage potentials to earth

• Operating mechanism partswhich are functionally impor-tant are made of corrosion-proof materials

• Bearings in operating mech-anisms are designed as dry-type bearings and do notrequire lubrication.

Tests for resistance tointernal arc faults

• Tests for verifying resistanceto internal arc faults shouldestablish proper protectionfor operating personnel.

• Tests for resistance tointernal arc faults can beagreed between the ownerand manufacturer inaccordance with VDE 0670Part 6 or IEC 60 298.

• The tests must be per-formed in accordance withVDE 0670 Part 6, AppendixAA or IEC 60 298,

Appendix AA• Definitions of criteria:– Criterion 1

Correctly secured doors,covers etc. do not open

– Criterion 2Parts of the enclosedswitchgear which may causea hazard do not fly off
