With the launch of domestic ZW32 vacuum circuit breaker, sn-10 less oil circuit breaker gradually replaced. The vacuum circuit breaker has fast breaking speed, strong dissociation, and is not easy to form arc reignition, which not only effectively limits the overvoltage of system operation, but also the dynamic and static contacts are not easy to be burned by arc, and there will be no leakage of other media. Therefore, small maintenance, long service life, these are less than the advantages of oil circuit breaker. However, the current online operation of vacuum circuit breaker with load pull, switch accidents occur from time to time, resulting in the whole circuit breaker burned out, resulting in shutdown, power failure, and even serious consequences of personnel burns.
