摘　　要：核燃料换料机是在特别危险环境中使用的特种操作设备,在初始设计和改造设计中均要特别注意电气安全问题,避免因电气保护设计不当、设备故障及外部故障引入等引发电气事故,直接或间接造成电气设备损坏、人身伤亡、核燃料组件破坏甚至更严重的后果。文章对接地、等电位联结、电气设备选择、电气设备保护、电气隔离、电磁辐射等应特别注意的电气安全问题进行了分析介绍。The nuclear fuel handling machine is the special equipment used in very dangerous environment, so it＇s re- quired to pay great attention to the electric safety in initial design and modification design, in order to prevent any electric accidents caused by improper electric protection design, equipment fault, and exterior fauh etc. , which may directly or in- directly result in electrical equipment damage, casualties, damage of nuclear fuel components, or even worse conse- quences. The paper introduces some electrical problems requiring special attention such as earthing, equipotential bonding, selection of electric equipment, protection of electric equipment, electric isolation, electromagnetic radiation, etc.
