Analysis and Discussion on the Lightning Protection and Grounding System in Subway and Light Rail Stations

文章对地铁及轻轨车站的防雷和接地系统进行了分析,并就外引接地极绝缘引入、金属屋面防雷和接地连接点间距等有关问题进行了探讨,提出了更加合理的解决方案,消除了工程技术人员的疑虑。

This paper analyzes the lightning protection and grounding system in subway and light rail stations. We also discuss some problems related to the insulated entering of the outside grounding pole, the lightning protection on the roof of metal and the distance between the grounding joints. Based on the analysis, we present more reasonable solving scheme to eliminate the engineers＇ doubts.
