HIGH VOLTAGE CIRCUIT-BREAKER WITH A COUNTER-CONTACT WHICH CAN BE ACTUATED

摘要

The invention relates to a high-voltage circuit breaker. The contact system of said high-voltage circuit breaker has a contact (9) which is actuated by a switch mechanism and a counter-contact (7) which can be actuated by means of an auxiliary mechanism, said counter-contact (7) being opposite said contact (9). According to the invention, the parallel current path which passes via the auxiliary mechanism is interrupted between the counter-contact (7) and a second connection of the high-voltage circuit breaker by means of an insulating part.
