ANTI-PUMP CIRCUIT BREAKER

摘要

ANTI-PUMP CIRCUIT BREAKER The circuit breaker is taught with an anti-pumping control circuit. If the circuit breaker closes on a fault and quickly reopens without the closing switch being either mechanically or electrically released in the interim, reclosure of the circuit breaker either by an automatic recloser or by the mere fact that the closing switch remains closed will be prevented until the closing switch is once again opened. In addition, if the closing switch is actuated prior to power being applied to the circuit breaker control system, the circuit breaker will not close when power is applied. The closing spring will be charged, however, for a subsequent circuit breaker closing after release and reactuation of the closing switch.
