To solve the problem of frequent pressurizing in LW10B-252 SF6 circuit breaker
cause analysis was conducted via disassembling the breakers.Subsequently
the outlet check valve of oil pump in the circuit breaker mechanism was found the source of frequent pressurizing.A solution to the check valve problem is therefore suggested.
