爆炸和火灾危险场所防雷装置检测若干技术要点解析

Analysis of Some Technical Points of Lightning Protection Device Detection in Explosion and Fire Hazardous Place

分析了爆炸和火灾危险场所防雷装置检测实际工作中经常遇到的技术问题。对现行有效的国家标准进行研究,得出结论:第二类防雷建筑物中长金属物的连接物无须检测过渡电阻,加油加气站彩钢板罩棚在满足相应要求时可作为接闪器,加油加气站利用不少于2根罩棚支撑柱作为引下线时,对引下线间距可不作要求。

This paper analyzes the technical issues that are often encountered in the practice of detecting lightning protection devices in explosive and fire hazardous place.Based on the study of the current effective national standard,the conclusion is drawn that the connection of long metal objects in the second type of lightning protection building is not required to detect the transition resistance.When meeting the corresponding requirements,color steel awning of fueling station can be used as air-termination systems.When the fueling station uses no less than 2 awning support columns as down-conductor systems,the down-conductor system spacing is not required.
