为了避免电源线路对雷电的感应和传输特性,时常引发雷击过电压侵入建筑物室内,损坏电气设备,乃至人员伤亡事故,通常是在电源线路上安装电源避雷器,然而由于一些技术人员对避雷器特性认识欠缺,造成后续设备或系统仍遭受雷击的现象。本文根据国家相关防雷技术规范介绍在电源线路上装设电涌保护器的基本原则。
In order to avoid the power line lightning induction and transmission characteristics, often lead to lightning over-voltage intrusion inside the building, damage to electrical equipment, and even casualties, power lines are usually installed on the power surge arresters, However, due to some technical personnel to understand the characteristics of arresters Lack of follow-up equipment or system caused by the phenomenon of lightning strikes. This article according to the relevant national lightning protection technical specifications introduced in the power line installed surge protector basic principles.
