摘要
基于220 kV乔长线杆塔及线路雷害事故情况分析,对其实施了杆塔接地改造,并对改造后的乔长线的接地电阻进行了理论计算后与实测接地电阻值进行比较,结果表明此次杆塔防雷接地改造取得了很好的效果。
The grounding alternation of the steel tower and the lightning fault in 220 kV Qiaochang transmission line is analyzed. After alternation, the calculated grounding resistance values are compared with the measured values. The result indicates that the altered effect is satisfactory.
