Why Is A Tripping Operation Required Before Operating The Sf6 Circuit Breaker's Operating Mechanism?

Before maintenance, sf6 circuit breaker operating mechanism should be opened first. When sf6 circuit breaker spring mechanism is still in the closed state, its contacts are energized or potentially energized. The operating mechanism may store spring energy or other mechanical stress. If maintenance is carried out directly without releasing these states, it may lead to unexpected action or arcing.
