摘要
统计忻州地区220 kV及以上架空输电线路近十年的雷击跳闸故障,对输电线路易发生绕击跳闸的原因以及防雷现状进行了分析,结合运行经验,提出了架空输电线路雷电绕击防护的新思路。
As to the lightning shielding failure trip of the Xinzhou overhead line of 220 kV or over of the past ten years, the reasons why trip fault by shielding failure is more likely to occur on the power lines and the prevention of lightning faults current situation are analyzed. The protective thought of lightning shielding failure on the overhead line is proposed.
