摘要
根据雷电定位系统统计数据,在实际雷电活动分布条件下,通过对同塔双回输电线路的耐雷性能进行分析,以110 kV竹防—竹石同塔双回输电线路为例,对其耐雷性能进行计算,并对引起该线路频繁跳闸的原因进行分析,提出防雷改造建议。
The lightning performance of double circuit transmission line on the same tower is analyzed under the real distribution of lightning activities with the help of statistic data of lightning location system.A 110 kV Zhufang-Zhushi double circuit transmission line is given as an example to show the calculation process,and the reason of frequent trip of the transmission line is analyzed and corresponding suggestions on the lightning protection is proposed.
