Definition of Hybrid Switchgear as per IEC 62271-205

Compact switchgear assemblies consist either of

components of air-insulated switchgear (AIS) or of a

combination of air-insulated switchgear and gas-

insulated switchgear (GIS), so called mixed

technology switchgear (MTS)

ELK-TK3S

Disconnectors can be used for bustransfer switching, e. g. in double or

multiple busbar arrangements of

SF6 gas insulated substations (GIS).

Switching sequence for the current

transfer in a GIS with double busbar:

Closing of disconnector No. 2 yields

distribution of the load current “I” onto

the two parallel paths “I1” and “I2” ac-

cording to the relation of the impe-

dances of both sections. Opening of

disconnector No. 1 in the third scheme

leads to the transfer of the load current

part “I1” from bus A to bus B.

IEC: The value of the rated bus-transfer current for both air- and gas-insulated

disconnectors shall be 80 % of the rated normal current. It will normally not

exceed 1600 A, irrespective of the rated normal current of the disconnector.
