摘要
为提高输电线路沿线整体防雷性能水平,结合珠三角某地区的110kV及以上电压等级的输电线路的运行的统计数据,总结出一套比较完善的输电线路防雷经验,分析了不同杆塔高度和形状的高压输电线路雷击特性的变化规律,为输电线路的沿途架设提供相应的理论数据参考,从而有效减少输电线路因雷击而造成的损失,具有一定的工程应用价值。
In order to enhance the lightning withstand level of the entire transmission lines, on the basis of the operation statistic data of 110 kV and above voltage transmission lines in Pearl River Delta Area, a set of impeccable experience of lightning protection is summarized, the change law of the lightning performance of high voltage transmission lines considering the influence of tower type is analyzed, a reference for the construction of transmission lines is provided and thus the economic loss of transmission lines caused by lightning is decreased, which has certain engineering application value.
