Dianci bileiqi, 2019 运用电磁暂态软件ATP-EMTP建立220kV复合材料横担输电线路模型,分析对比了复合横担输电杆塔和酒杯塔A、B、C三相临界反击闪络雷电流的大小,并分析了不同冲击接地电阻、不同工频相角下复合材料横担塔反击、绕击耐雷水平以及最大绕击电流,验证复合材料输电杆塔耐雷性能优于常规酒杯塔,为复合横担的结构设计与优化提供参考。

Dianci bileiqi, 2008 介绍了可控放电避雷针的保护原理和线路避雷器的保护原理以及超高压输电线路典型雷击障碍的情况,并对障碍原因进行了分析和探讨。当被保护对象遭受绕击概率允许达到0.1%时,可控放电避雷针的保护角可达66.4°。对主要参数绕击概率和保护范围而言,可控放电避雷针的保护特性明显优于富兰克林避雷针;500 kV线路在雷电活动强的地区安装一组金属氧化物避雷器,即使杆塔冲击接地电阻达40Ω,耐雷水平也能达350kA,即装一组金属氧化物避雷器基本上能满足线路防雷要求。
