Abstract:
A high-voltage circuit breaker, comprising:three circuit breaker poles; and at least one interrupter unit for each of the circuit-breaker poles, each of the at least one interrupter unit having an actuatable switching contact which is actuated by a joint actuating mechanism via a respective switching rod so that in the event of a closing operation, a time delay is provided at least between a closing of the interrupter units of two of the circuit breaker poles, at least the respective switching rod of a first one of the circuit-breaker poles being connected to the actuating mechanism via levers, only at least one of a second one of the circuit-breaker poles and a third one of the circuit-breaker poles is connected to the actuating mechanism via spring elements, the spring elements being compressible in the event of the closing operation and expand after contact has been made.
