摘　　要：为防护雷击电磁脉冲(电涌)对电子信息系统造成干扰破坏,介绍了在防雷设计中如何选择浪涌保护器(SPD)。对浪涌保护器的原理、技术参数、安装及级间耦合等进行分析,提出了在具体防雷方案设计中应注意的若干问题,及在选择使用浪涌保护器时涉及的几个主要步骤。指出合理选用浪涌保护器可有效降低雷击风险,避免雷电灾害。How to select surge protective device （SPD） in lightning protection design in order to defend the damage to the information system from lightning electromagnetic pulse（LEMP） was introduced. The principle, technical pa- rameter, installation and interstage coupling of SPD were expounded, and several problems need to be attended in specified lightning protection project design and several main steps in selecting SPD were put forward. It was pointed out that reasonable choice of SPD can reduce the lightning risk and avoid the lightning disasters.
