现代有轨电车供电系统接触网防雷技术研究

根据苏州市当地的环境、气象、地质等条件和雷电活动规律,分析了几种雷击发生闪烁事故的风险,对苏州高新区现代有轨电车1号线工程项目的供电系统接触网结构特性进行了深入分析和研究,通过和国家电网供电部门的技术人员一起对本项目进行了研究和论证,认为可以取消正线和车辆基地供电系统在接触网上的防雷架空地线,寻找采用其他方法代替避雷线的防雷作用。此举既保障了车辆的安全运营,又节省了投资费用,也提高了线路沿线的景观美感。

On Lightning-proof Technique for the Power Supply System Catenary of Modern Tram

According to the local environmental,meteorological and geological conditions,as well as the law of lightning activity in Suzhou City,the risk of flicker accidents occurred in lightning storms is analyzed.The characteristics of catenary structure in the power supply system of the modern tram Line 1 project that runs in Suzhou High-tech Zone are analyzed in depth.Through working with the technical staff of power supply system department in National Grid,the overhead lightning -proof ground wire installed in power supply system of the main lines and depot is considered as redundant,it should be replaced by other methods.This initiative can protect the safe operation of vehicles,save investment costs and strengthen landscape beauty along the tram line at the same time.
