■ Traction power supply systems

Environmental independence

Enclosures with modular stand-ard housings made of corro-sion-resistant aluminium alloymake 8DA and 8DB switchgear

• Insensitive to aggressiveambient conditions such as

– salt water– air humidity– dust– temperature

• Primary part is hermeticallytight to ingress of foreignbodies, such as

– dust– dirt

• Independent of site altitude

Compact design

Thanks to the gas insulation,narrow panel widths of only600 mm up to 40.5 kVare possible.

Thus,

• Existing switchgear roomscan be used effectively

• New constructions cost little

• Costly city-area space is saved

Almost maintenance-freedesign

Switchgear housings designedas sealed pressure systems,maintenance-free switchingdevices and enclosed cableplugs ensure

• Maximized power supplyreliability

• Personnel safety

• Reduced operating cost

• Cost-efficient investment

Innovations

The use of digital secondarysystems and combined protec-tion and control devices ensure

• Clear integration in processcontrol systems

• Flexible and highly simplifiedadaption to new systemconditions and thus tocost-efficient operation

Basic panel design

Design

Panel

• Single-pole metal-enclosed

• Metal-clad

• Basic construction of cast-aluminium housings

Insulating system

• Panel housings filled withSF6-gas

• Features of SF6-gas:– non-toxic– odourless and colourless– non-inflammable– inert– heavier than air– electronegative (high-quality

insulator)

• Overpressure of SF6-gas inthe panel housings:

– normally 50 kPa up to120 kPa (depending oninsulation level and ratednormal current)

– design pressure 180 kPa– design pressure

of SF6-gas 80 °C– operating pressure of rupture

diaphragm ≥ 300 kPa– bursting pressure ≥ 600 kPa

Panel pole

• Poles arranged one behindthe other

• Consisting of a vertical hous-ing containing the vacuuminterrupter

• Arranged on top:– for single-busbar switchgear

Gas compartment principle

• Optimal availability by means of– sealed pressure system– distribution of gas compartments– arrangement of manometers for

pressure monitoring– position of three-position

disconnectors

• Operation and monitoring of abusbar section only possible if allbusbar housings involved are ingood working order:

– operation and monitoring of theentire busbar section as one gascompartment is sufficient

– lining up individual panels to oneswitchgear assembly forms one gascompartment for each busbar phase

– manometer for this gas compart-ment mounted in one end wall

• Operation and monitoring of onebusbar section of a single-busbarswitchgear assembly also possibleif a feeder is faulty:

– “feeder” gas compartment separatedfrom “busbar” gas compartment

– 3 circuit-breaker housings intercon-nected by a pipe, ensuring individualgas monitoring for each panel

– manometer for this gas compart-ment mounted at the panel front

• Operation and monitoring of adouble-busbar switchgear also possi-ble if one busbar system or thedisconnector is faulty:

– gas compartments of both busbarsseparated from the gas compart-ments of both disconnectors

– 1 gas compartment available eachfor the 3 circuit-breaker housings,the disconnector housings and thethree-position disconnectorhousings

– 3 manometers mounted on the pa-nel front to monitor the gas pressure

• Separate, defined pressure relief foreach gas compartment

• Pressure monitoring via manometersin connection with alarm contactsto signal any increase or drop inpressure

• Ratings according to IEC 62 271-200resp. VDE 0671-200 remain un-changed after more than 20 yearsof operation. During this time, norefilling of SF6-gas will be necessary

Standards

Standards

The 8DA/8DB switchgearcomplies with the relevantstandards and specificationsapplicable at the time of thetype tests.

In accordance with the harmo-nization agreement reachedby the EU countries, theirnational specificationsconform to the IEC standard.

Type of service location

8DA/8DB switchgear can beused as an indoor installation inaccordance with VDE 0101 orthe Harmonization DocumentHD 637 S1 (Power installationsexceeding 1 kV AC)

• Outside lockable electrical ser-vice locations at places whichare not accessible to the pub-lic. Enclosures of switchgearcan only be removed withtools.

• Inside lockable electricalservice locations. A lockableelectrical service location is aplace outdoors or indoors thatis reserved exclusively forhousing electrical equipmentand which is kept under lockand key. Access is restricted toauthorized personnel andpersons who have been prop-erly instructed in electricalengineering. Untrained orunskilled persons may onlyenter under the supervisionof authorized personnel orproperly instructed persons.

Aseismic capacity (option)

• 8DA/8DB switchgear can beupgraded for regions at riskfrom earthquakes.

For upgrading, earthquakequalification testing is carriedout in accordance with thefollowing standards:

• IEC 68-3-3 1993

• IEC 68-2-6 1995

• IABG TA13-TM-002/98(guide)

Within the range of the prevail-ing earthquake frequenciesfrom 1 Hz to 35 Hz, the category1 required response spectrumto IABG TA13-TM-002/98 coversthe following response spectra:

• Uniform BuildingCode zone 3

• Seismic RequirementsSpec. 9067; Department ofWater & Power, Los Angeles

• GTS – 1.013 ENDESA, Chile

• VDE 0670-111

Insulating capacity

• The insulating capacity is veri-fied by testing the switchgearat rated short-duration power-frequency withstand voltageand rated lightning impulsewithstand voltage in accord-ance with IEC 60 694 andVDE 0671-1000(see following table).

• The rated values refer to sealevel and to normal atmos-pheric conditions (1013 hPa,20 °C, 11 g/m3 water contentin accordance with IEC 60 071and VDE 0111).

• With increasing altitude, theinsulating capacity decreases.This influence can be neglec-ted for gas-insulated switch-gear 8DA/8DB.

Internal arc classification


Standards

Internal arc fault test

• Tests for verifying the internalarc classification should es-tablish proper protection foroperating personnel

• The tests must be per-formed in accordance withIEC 62 271-200/VDE 0671-200

Criteria for internal arc faults

• Criteria according toIEC 62 271-200/VDE-0671-200with respect to thebehaviour in case of internalarc faults

• Definitions of criteria:– Acceptance criterion 1

Covers and doors remainclosed. Limited deformationsare accepted

– Acceptance criterion 2No fragmentation of theenclosure. No projection ofsmall parts above 60 g weight

– Acceptance criterion 3No holes in the accessiblesides up to a height of 2 m

– Acceptance criterion 4Indicators do not ignite due tothe effect of hot gases

– Acceptance criterion 5The enclosure remainsconnected to its earthingparts

Climate andambient conditions

8DA/8DB indoor switchgear arehighly insensitive to climateand ambient conditions due tothe following features:

• Gas insulation of all high-voltage parts (no negativeeffects on the primary part ofthe switchgear)

• No cross-insulation of isolat-ing distances from phase tophase

• Bearings in operating mecha-nisms are designed as drybearings

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

• Insensitive to ambient effectssuch as

– natural foreign bodies– chemically active pollutants– small animals and insects

Additional safety

• No short-circuit arcingbetween phases due tosingle-pole metal enclosure

• Earth-fault arcing betweenphase and earthed enclosureharmless due to

– low current arcs incompensated and insulatedsystems

– no important damages toinsulation, main circuits andmetal enclosure

• In effectively or resistivelyearthed systems the partitionbushings restrict the effects ofarc faults to the gas compart-ment affected (adjacent polesare not affected)

• Any excess pressure is relievedby means of rupture dia-phragms: the aluminium en-closure does not tear open

• Probability of arcingconsiderably lower than inair-insulated switchgear asthere are no effects due to

– pollution layers– moisture– small animals and foreign

bodies

• Maloperation is practically ex-cluded by logical arrangementof operating elements andlogical mechanical interlocks

• Short-circuit-proof feederearthing by means of three-position disconnector in com-bination with vacuum circuit-breaker
