摘　　要：继电器是核电厂运行的关键节点,直接影响核电厂的安全性、可靠性和经济性。而核电厂继电器的种类众多、数量庞大而且故障率较高,是核电厂安全高效运行的难点之一。继电器和接触器配合使用能够实现很多有用的功能,包括定时控制、定量控制、连锁控制和欠压保护等。本文探讨了核用继电器的老化机理与失效模式,用试验实例阐述核用继电器的失效分析过程。Relay is the key node of nuclear power plant operation,which directly affects the safety,reliability and economy of nuclear power plant.The nuclear power plant relay is one of the difficulties of safe and efficient operation.The combination of relay and contactor can realize many useful functions,including timing control,quantitative control,interlock control and undervoltage protection.In this paper,the aging mechanism and failure mode of nuclear relay are discussed.Finally,the failure analysis process of nuclear relay is illustrated with a test example.
