摘要
雷电活动较强的地区雷害已成为当地电力线路跳闸的主要原因,但常用的防雷措施难以达到良好的防雷效果。通过对我国南方某地区雷害情况的统计分析,以及对其常用的多种防雷措施的对比与效果研究,提出了电力线路小分段绝缘防雷措施,阐述了该措施的实施方法,并以实际改造案例验证了该措施的有效性。
In the place where lightning takes place frequently,the lightning disturbance is the major cause of power lines trip.The ordinary lightning-proof measures fail to perform well.According to the statistics analysis on the lightning data in certain Southern region in China,the small sub-insulated lightning-proof measures and its implementation in power lines are presented based on the comparison and performance research of several lightning-proof measures.The real case of this application proves its effectiveness.
