由于我国的地域广大,因此经常会出现因为雷击导致的设备损坏和人员伤亡的事故。根据牵引供电系统运营部门统计数据分析,现如今我国开通了9.7万千米的铁路线路中有些线路出现雷击次数非常频繁。因此,对于接触网防雷设计要非常重视,接触网的防雷设计主要遵循防雷减灾、综合保护、系统优化的原则和运输安全为目的来进行设计。本文以铁路接触网防雷技术为引导,围绕铁路接触网防雷技术来分析问题。文章首先就接触网和雷电对电网的危害进行了阐述,继而对关于铁路接触网防雷技术的现状进行分析研究,从中体现主要问题归纳出针对性的对策。
Due to the vast territory of our country, accidents of equipment damage and casualties due to lightning strikes often occur. According to the statistical analysis of the traction power supply system operation department, nowadays some 97,000 kilometers of railway lines are opened in our country and the number of lightning strikes is very frequent. Therefore, the design of catenary lightning protection should be taken seriously. The lightning protection design of catenary mainly follows the principles of lightning protection and disaster reduction, integrated protection, system optimization and transportation safety. In this paper, the railway contact network lightning protection technology as the guide, around the railway contact network lightning protection technology to analyze the problem. Firstly, the article describes the hazards of the catenary and the lightning to the power grid, then analyzes and studies the present situation of the lightning protection technology of the railway catenary, and summarizes the main problems from the countermeasures.
