摘　　要：受雷电等灾害天气的影响,突然断电将导致用电设备的损坏。介绍了建筑物防雷设计中电涌保护器所起的作用以及电涌保护器参数的选择;针对由引线额外残压形成的问题,分析了普通接线与凯文接线两种方式的特点,以选择合适的安装方式确保用电设备的安全运行。In severe weather like thunder and lightning, sudden power failure will cause damage to electric equipment. The function of surge protection device in building lightning protection design and its parameter selection are introduced. With regard to the problems resulting from the additional residual pressure of lead cable, the conventional wiring and Kevin wiring are analyzed in order to select the appropriate installation method to ensure the safe operation of electric equipment.
