摘　　要：在厂用电系统中,弹簧储能式真空断路器在运行过程中经常会出现各种不同的故障,导致断路器不能正常分、合闸,严重时影响机组负荷。通过分析、处理了一起VB2型弹簧储能式真空断路器拒合、合闸线圈烧毁的故障,提出了断路器运行维护重点检查项目,对运维中经常出现的故障进行了原因分析。In the power system of the factory, the spring energy storage vacuum circuit breaker often has various faults during the operation, which causes the circuit breaker to fail to be divided and closed normally, which seriously affects the unit load. By analyzing and dealing with the failure of VB2 spring energy storage vacuum circuit breaker and the closing of the closing coil, a key inspection project of circuit breaker operation and maintenance was put forward, and the causes of frequent failures in operation and maintenance were analyzed.
