introduction：In this paper, the fault probability distribution and the advantages and disadvantages of mechanical linkage and electrical linkage are compared，The reliability of high voltage circuit breaker with electrical and mechanical linkage is analyzed。 1 introduction The high voltage circuit breaker plays the role of control and protection in the power system，The reliability of its performance is related to the safety of the power system、Steady operation。In order to reduce the occurrence of non-full phase switching，Some places need to use three-phase mechanical linkage。Some users more intuitively judge that the reliability of three-phase mechanical linkage circuit breakers is much greater than that of electrical linkage circuit breakers，However, the actual situation requires concrete analysis。
