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.

Busbars

• Metal-enclosed busbarcompartment

• Three-pole design,bolted from panel topanel

• Easy switchgearextension

• Made of copper:Round-edge copper forup to 1200 A

Option:Shrink-on sleeve

HV CL fuse assembly

• For fuse panel type FS

• For busbar voltage meter-ing panel type MS

• 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

Ready-for-service indicator(option for three-positionswitch)

• Self-monitoring; easy toread

• Independent of tempera-ture and pressure variations

• Independent of site altitude

• Only responds to changesin gas density

• Option: Alarm switch“1NO contact”

Mode of operation

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.

Overview of standards

SIMOSEC ANSI switchgear com-plies with the following rele-vant standards and specifica-tions as applicable:

• ANSI/IEEE Std. C37.20.3-2001

• ANSI/IEEE Std. C37.20.4-2001

• ANSI/IEEE Std. C37.57-2003


• ANSI/IEEE Std. 1247-2005


• CSA C22.2 No. 193-M 1983

• CSA C22.2 No. 31-04

• EEMAC G11-1(measurement of Corona)

• IEC 62 271-105

Third-party listing

SIMOSEC ANSI is available formost configurations with ULor C-UL listing.

Type of service location

SIMOSEC ANSI switchgear canbe used as an indoor installa-tion in accordance with NEC(NFPA70)

• 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

Site altitude in m/ft above sea level

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.

Standards


• For cable testing– the installation and

operating instructions ofthe switchgear

– 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

Protection against solidforeign bodies, electric shockand ingress of water

SIMOSEC ANSI switchgearfulfills acc. to the standardsANSI/IEEE C37.20.3 thefollowing type of protection:All openings in the enclosureprevent the entrance of a rodwith a diameter of 3.2 mm/0.13 inch.
