Abstract. The purpose of an opening switch is simply to stop the flow of current in the circuit branch containing the switch. Prior to this action, of course, the opening switch must first conduct the current as required--that is, operate as a closing switch. To accomplish current interruption, the opening switch must force the current to ...

Principle of Energy Storage Switch. The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the ...
