摘　　要：为了探究如何优化配置线路避雷器数量,达到防雷保护效果又不失技术经济性问题,以110 kV架空输电线路为研究对象,采用电磁暂态仿真计算软件ATP/EMTP,分别搭建输电线路雷电反击和绕击仿真模型,计算出几种不同避雷器安装方式下的线路耐雷水平。分析表明:相对于线路不安装避雷器,每基杆塔安装避雷器线路的耐雷水平提高了73%~83%,每隔两基杆塔安装避雷器线路的耐雷水平提高了31%~36%。In order to study how to optimize the number of line arresters to achieve good lightning protection effect and technical economy, taking the 110kV overhead transmission line as study objective, the simulation models of counterattack and shielding failure for transmission line are respectively established using the electromagnetic transient simulating calculation software ATP / EMTP, and the lightning withstand levels for several installation modes of arrester are calculated. The analysis shows： compared to the line without arrester, the lightning withstand level of line when each base tower is equipped with arrester has improved by 73 %-83 %; the lightning withstand level of line when a arrester is installed for every 2 base towers has improved by 31%-36%.
