| Abstract: | In the faults of the hydraulic mechanism for high-voltage circuit breaker,the frequent bulge of the oil pump of hydraulic mechanism accounts for a large proportion.Taking the 3AQ/3AT circuit breaker as an example,we analyzed various causes of frequent bulge of the oil pump of hydraulic mechanism.Furthermore,we presented some methods to deal with the faults according to the corresponding causes in order to provide experience for the treatment of the same type of circuit breaker with similar faults. |
