防雷工程中电涌保护器的选择和应用

The Selection and Application of Surge Protection Device in the Lightningprotection Engineering

本文简述了在防雷设计中如何选择电涌保护器，并对电涌保护器的原理、技术参数、安装及级问耦合等进行了分析，提出在具体防雷方案设计中应注意的若干问题，以及在选择使用电涌保护器时涉及的几个主要步骤。

The paper introduces how to select surge protection device （SPD） in the design of the lightning-protection engineering, analyses the theory, technical parameter, installation and interstage coupling of SPD, and eventually presents several problems need be attended in specified lightening-protection project design and several main steps during the selection and using of SPD.
