文章在现有电气化铁路接触网防雷研究的基础上,分别计算出接触网系统在有、无避雷线的情况下,雷击电气化铁路线路附近地面、接触网支柱、接触网导线时,能够引起接触网闪络的雷电流幅值与概率;分析了接触网系统中有避雷线时,避雷线在不同的保护角度下,雷电绕击接触网系统的概率。对接触网系统作出了有、无避雷线时耐雷水平的比较,避雷线的屏蔽和分流作用使接触网耐雷水平提高。对接触网线路的大气过电压防护措施提出了建议。

Based on the lightning protection research of OCS at present,it is separately calculated the lightning current amplitude and probability that may cause flashover of the OCS with or without overhead ground wire in OCS, when lightning happened on the ground close to the electrified railway line, happened to the pillar and contact wire of OCS; it is analyzed the probability of lightning shielding failure, from different protection angles of the overhead ground wire in OCS. It is compared the lightning resisting level of the OCS with or without overhead ground wire. The functions of shielding and shunting of overhead ground wire increase the lightning resisting level of OCS. Proposals are put forward about the atmospheric over-voltage protection measures of OCS.
