HIGH-VOLTAGE SWITCHING SYSTEM

HIGH-VOLTAGE SWITCHING SYSTEM

The invention relates to a high-voltage switchgear comprising a switchgear housing (10) which is filled with an insulating gas, for example SF6, and in which at least one pair of contacts formed by a stationary and a mobile contact element (22, 20) having an actuating drive and electric conductors a...

description The invention relates to a high-voltage switchgear comprising a switchgear housing (10) which is filled with an insulating gas, for example SF6, and in which at least one pair of contacts formed by a stationary and a mobile contact element (22, 20) having an actuating drive and electric conductors are arranged, said contacts and conductors being insulated against earth, the switchgear housing (10) defining a gas chamber. At least one insulating bush (28) having a phase contact (30) is provided on the switchgear housing, said bush being covered by an insulating plug (32). At least one further contact system (14) is located outside the switchgear housing (10) on the at least one insulating bush (28) and functions as an ultra-fast earthing switch which shortcircuits the phase contact (30) of the insulating bush (28) by means of the ground potential in the event of a fault condition in the switchgear housing (10). The mobile piston (18) of the piston-cylinder arrangement has an edge (24) on its end face facing the stationary contact element (22) to be contacted, said edge cutting through the insulating plug (32) in the event of a fault condition.
