摘　　要：在10 kV系统中,为了有效防止10 kV开关误合闸,在控制回路中,都设计有合闸闭锁回路,通过合闸闭锁回路结合闭锁电磁铁来实现防误。然而对于现有的10 kV合闸闭锁回路,没有对其进行监测,对维护和监视带来了不便。在传统的合闸闭锁回路上进行优化改进,提出一种可以监测10 kV合闸闭锁回路的方法,来提高10 kV系统电气闭锁可靠性。In the 10 kV system,in order to prevent the false switch-on of 10 kV circuit breaker,the switchon blocking circuit is designed in the control circuit,by which the false switching prevention is realized through switch-on blocking circuit coupled with blocking electromagnet.However,the existing 10 kV switch-on blocking circuit is not monitored,which may bring about inconvenience to maintenance and monitoring.The traditional switch-on blocking circuit is improved and optimized,an approach for monitoring 10 kV switch-on blocking circuit is proposed to enhance the reliability of electric locking for the 10 kV system.
