Three-phase insulated high voltage switch gear, has supporting unit with insulating connector provided between circuit breaker and bus bar region, where connector is formed such that circuit breaker is stabilized in its position

摘要

The switch gear has several system components arranged in an enclosure housing. A terminal box (11) arranged as an enclosure bushing is provided in the housing for each phase. A supporting unit is rigidly connected with the housing, and is provided with an insulating connector (18) between a circuit breaker (24) and a bus bar region (9). The connector is formed such that the circuit breaker is stabilized in its position. A mechanical switching impulse is derived during the switching of the circuit breaker.
