工业建筑防雷系统剖析

随着工业控制系统内电子设备的数量和规模不断扩大，而电子设备普遍存在着绝缘强度低，过电压耐受能力差的弱点，当其因雷击受到电磁脉冲，特别是闪电电磁脉冲的袭击，会出现不同程度的运行故障．甚至造成巨大损失。因此工业建筑中的电子设备应进行多级分流（不少于三级防雷保护）的防雷措施．确保生产装置安、稳、优地运行。

Analysis of Lightning Protection System for Industrial Buildings

The number and scale of electronic devices in industrial control systems are increasing,however,such electronic devices have commonly weaknesses such as low insulation strength and poor overvoltage tolerance,which may show various operating failures,or even result in huge loss when they suffer lightning strike and are attack by electrical pulse,specially lightning pulse.Therefore,multi-stage(at least three stages) lightning protection measures should be adopted for the electronic devices in industrial buildings,so as to make sure the production facilities are operating in a safe,stable and optimum manner.
