摘　　要：反应堆保护系统T3定期试验,由于试验开关318CC的触点缺少监测手段,导致停堆断路器试验期间存在较高的误停堆风险。本文介绍了ATWT停堆闭锁回路增加监测功能的设计与调试,通过ATWT停堆闭锁回路的改进,可完成开关触点状态的监测,能够有效降低318CC的敏感性,从而降低停堆系统T3试验的误停堆风险,对于电厂安全稳定运行具有积极意义。The T3 Periodic test of reactor protection system,as a result of the test switch 318 cccontact the absence of monitoring means,lead to shua down the breaker exists high risk of accidentally shutdown during the test.This paper introduces the ATWT shutdown locking loop increase monitoring function design and debugging,through ATWT shutdown locking loop improvement,can complete the switch contact state monitoring,can effectively reduce the sensitivity of 318 cc,thereby,reduce the risk of shutdown system of T3 test mistakenly shut down,has positive meaning for the safe and stable operation of power plant.
