摘　　要：针对某核电厂在执行主消防泵投入热备用试验过程中出现的就地控制盘失电事件展开了故障分析,确定故障源头为压敏电阻的短路。随后,从人为因素、环境因素及压敏电阻特性因素方面对压敏电阻的短路进行了分析,确定了短路发生的根本原因。最后,提出了类似事件的处理建议,从而降低该类故障的发生率,提升核电厂的安全性和稳定性。In view of the power loss event of the local control panel during the hot standby test of the main fire pump in a nuclear power plant,the fault analysis is carried out,and it is determined that the fault source is the short circuit of the varistor.Then,the short circuit of varistor is analyzed from the aspects of human factors,environmental factors and varistor characteristics,and the root cause of short circuit is determined.Finally,suggestions for handling similar incidents are put forward to reduce the incidence of such failures and improve the safety and stability of nuclear power plants.
