Abstract This paper discusses the maintenance and inspection method of intelligent low-voltage circuit breaker, which is caused by a skip trip event caused by the failure of low-voltage circuit breaker when the feeder cable of low-voltage auxiliary power system in thermal power plant is short circuited. This paper briefly introduces the characteristics of the current transformer of intelligent low-voltage circuit breaker, and puts forward maintenance and inspection methods of the circuit breaker, focusing on the test methods of the intelligent protector. In order to ensure the reliable operation of circuit breaker, suggestions for routine maintenance are put forward.
