摘　　要：国内部分接触轨供电的地铁高架区间中缺乏对设备的防雷保护详细分析和防雷设计。为了达到全面的防雷保护效果,采用滚球法和操作方便的作图法对单线以及多线桥梁中的防雷保护范围进行详细分析,针对不同场景给出了具体的防直击雷的补加措施及较为通用的设计分析方法。There is a lack of detailed analysis and design of lightning protection for the equipment in the elevated section of the subway powered by contact rail in China.In order to achieve the comprehensive lightning protection effect,the rolling ball method and the easy to operate drawing method are used to analyze the lightning protection range of single line and multi-line bridges in detail,and specific additional measures to prevent direct lightning strikes and more general design and analysis methods are given for different scenarios.
