通信设备的系统防雷机理
Systemic Lightning Protection Mechanism of the Telecommunication Equipments
摘要 通信设备的防雷是一个典型的系统工程,需要综合考虑机房防雷与设备防雷,二者缺一不可。本文从分析雷击发生机理与感应雷的侵入途径着手,对不同的防雷区域进行划分,阐述了滚球法的应用和防雷的基本原则——等电位防雷。

Abstract The lightning protection of the telecommunication equipment is a systemic
project related to the protection of both structures and equipments against lightning.
The lightning occur mechanism, causes of thunderstorm overvoltages, lightning
protection zones concept, application of rolling sphere method and lightning protection
equipotential bonding were discussed in the article.
Keywords lightning protection zones(LPZ), rolling sphere method, equipotential
bonding
