Characteristics
• Switch positions:– CLOSED-OPEN
or– CLOSED-OPEN-GROUNDED
• Designed as a multi-chamberswitch incorporating thefollowing functions
– Switch-disconnector and– Make-proof grounding switch
• Operation via gas-tightwelded bushing at the frontof the switchgear vessel
• Switching functions asgeneral purpose switch-disconnector according toANSI/IEEE C37.20.3 *
Mode of operation
The switch shaft with themoving contacts rotates insidethe chamber containing thefixed contacts.
Compression vanes, whichrotate in conjunction with theswitch shaft, divide the arcingchamber into two subchamberseach of which changes in con-junction 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 GROUNDEDfunctions cannot be imple-mented simultaneously.

• HV CL fuse linksacc. to ANSI/IEEEC37.41/C37.46 *
– As short-circuit protec-tion before transformers
– With selectivity (depend-ing on correct selection)to upstream and down-stream connected equip-ment
• Requirements fulfilled asHV alternating currentswitch fuse combination
• Selection of HV CLfuses for transformers
• Fuse replacement possi-ble only when feeder isgrounded
• Option: Shunt release onoperating mechanism oftwo/three-position switch-disconnector
• Option: “Tripped indica-tion” of two/three-positionswitch-disconnector intransformer feeder (trans-former switch) for remoteelectrical indication withone normally-open con-tact (1NO)
“HV CL fuse tripped”
Following the tripping of anHV CL fuse link, the mecha-nism for charging the springmust be set to the “OPEN”position
Subsequently, groundingcan be implemented bymeans of the two/three-position switch-disconnec-tor and e.g., the fuse can bereplaced.
Replacement of HV CL fuselinks
• Isolating and groundingof the transformer feeder
• Subsequent manualreplacement of theHV CL fuse links

• Standard:As detachable levermechanism
• Spring-operated mecha-nism
– For cable-switch paneltype CS
– For all two/three-positionswitches (except in paneltype FS)
• Spring-operated/stored-energy mechanismFor fuse panel type FS aswell as for busbar voltagemetering switch paneltype MS
The two/three-positionswitch is operated via arocker with metal bellowswhich is gas-tight andwelded at the switchgearvessel.
Motor operatingmechanism (option)
The manual operating mech-anisms can be equipped withmotor operating mechanismsfor the two/three-positionswitch-disconnector.
Operating voltages for motoroperating mechanisms:– 24, 48, 60, 125 V DC– 50/60 Hz 120 and 240 V AC
Electrical operation:
• Standard: Remote opera-tion (applied to terminal)
• Option: Local operationby momentary-contactrotary control switch
Shunt release (option)
Spring-operated/stored-energy mechanisms can beequipped with a shunt re-lease. Remote electricaltripping of the two/three-position switch-disconnectoris possible via the magneticcoil of the shunt release,e.g., transformer overtem-perature tripping.
To avoid thermal overloadingof the shunt release in theevent of a continuous signalthat may be applied, theshunt release is switched offvia an auxiliary switch whichis mechanically coupled withthe three-position switch-disconnector.
Auxiliary switch (option)
Each operating mechanismof the two/three-positionswitch-disconnector can beoptionally equipped with anauxiliary switch for theswitch position indication:– Function switch-discon-
nector or disconnector:CLOSED and OPEN:2NO + 2NC

For the ready-for-service indi-cator, a gas-tight measuringbox is installed on the insideof the switchgear vessel.
A coupling magnet, whichis fitted to the bottom endof the measuring box, trans-mits its position to an outsidearmature through the stain-less steel switchgear vessel.This armature moves theready-for-service indicator ofthe switchgear.
While changes in the gasdensity during the loss ofgas, which are decisive forthe insulating capacity, aredisplayed, temperature-dependent changes in thegas pressure are not. The gasin the measuring box has thesame temperature as that inthe switchgear.
The temperature effect iscompensated via the samepressure change in both gasvolumes.

• Outside lockable electricalservice locations at placeswhich are not accessible tothe public. Enclosures ofswitchgear can only beremoved with tools.
• Inside lockable electricalservice locations. A lockableelectrical service location isa place outdoors or indoorsthat is reserved exclusivelyfor housing electrical equip-ment and which is kept un-der lock and key. Access is re-stricted to authorized person-nel and persons who havebeen properly instructed inelectrical engineering.Untrained or unskilled per-sons may only enter underthe supervision of authorizedpersonnel or properly in-structed persons.
Terms
• “Make-proof groundingswitches” are groundingswitches with short-circuitmaking capacity according toIEC 62 271-102
• Switch-disconnector corre-sponds to interrupter switch
• HV CL are high-voltagecurrent limiting fuse links

Insulating capacity
• 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 IEC 60 694/VDE 0670-1000 andANSI/IEEE C37.20.3.
• The rated values are referredto sea level and to normalatmospheric conditions14.7 PSI, 68 °F, 0.00068 lb/ft3
humidity in accordance withIEC 60 071/VDE 0111 andANSI/IEEE.
• The insulating capacitydecreases with increasingaltitude.For site altitudes above1000 m/3281 ft (above sealevel) the standards do notprovide any guidelines for theinsulation rating. Instead,special regulations apply tothese altitudes.
Site altitude
• As the altitude increases, theinsulating capacity of insula-tion in air decreases due tothe decreasing air density.
• For site altitudes above1000 m/3281 ft a higherinsulation level must beselected. This results fromthe multiplication of therated insulation level for0 mm/0 ft to 1000 m/3281 ft(above sea level) with alti-tude correction factor Ka.
Result:
According to the abovetable, a switchgear for arated voltage of 27.6 kV isto be selected.

– the information on manu-facturer-dependent cable
sealing ends– the cable version
(e.g. paper-insulated mass-impregnated cables, PVCcables or XLPE cables)must be observed.
Cable testing
• For switch-disconnectorfeeders
• DC voltage test
before the test:
Remove or disconnect anyvoltage transformers at thecable connection in SIMOSECANSI switchgear.
SIMOSEC ANSI switchgearfor rated voltages up to27.6 kV can be subjected tocable tests at a max. DC testvoltage of 70 kV. The voltageat the busbar may be 27.6 kVin this case.

Climate and ambientconditions
SIMOSEC ANSI switchgear maybe used, subject to possible ad-ditional measures – e.g. panelheaters or floor covers –under the following ambientconditions and operatingtemperatures:
• Ambient conditions– Natural foreign materials– Chemically active pollutants– Small animals
• Operating temperaturesThe operating temperaturesare classified according toANSI/IEEE C37.20.3
SIMOSEC ANSI switchgear islargely insensitive to climateand ambient conditions byvirtue of the following features:
• No cross insulation forisolating distances betweenphases
* VLF = Very Low Frequency.Refer to IEEE Standard 400.2-2004“IEEE Guide for Field Testing ofShielded Power Cable SystemsUsing Very Low Frequency (VLF)”.For cosine-rectangular waveform,the rms value is taken as equal tothe peak value. For sinusoidalwaveform, the rms value is 0.707times the peak value, if distortion isless than 5 %.
• Metal enclosure of switchingdevices (e.g. three-positionswitch) in gas-filled stainless-steel switchgear vessel
• Dry-type bearings inoperating mechanism
• Essential parts of the operat-ing mechanism made ofcorrosion-proof materials
• Use of climate-independentcable-type current trans-formers
• All contacts (switch discon-nector and make-proofgrounding switch) are main-tenance-free
• Joints of the energizedcopper bars are silver plated
• Under indoor operatingconditions, SIMOSEC ANSIrequires low maintenance
