Abstract Based on the introduction of the VEX type vacuum circuit breaker's electric control circuit and the loop disconnection in 35kV electric system, this paper discusses the control loop disconnection in the VEX type vacuum circuit breaker and solves the situation by the fault analysis for the non-regular and irregular relay protection device reports the control loop disconnection in the commissioning of a new 35kV substation, then summarizes the main reasons of the fault and offers a more comprehensive understanding to the 35kV circuit breaker.
