摘　　要：带串联间隙的避雷器是10 kV配网线路较为有效的防雷措施,配网线路避雷器间隙距离没有标准规定,导致产品间隙距离偏差较大,本文通过试验得出不同间隙的U50击穿电压,以确定串联间隙的合适距离。Lightning arrester with series gap is a more effective lightning protection measure for 10 kV distribution network lines.There is no standard specification for the gap distance of lightning arrester in distribution network lines,which leads to large gap distance deviation of products.In this paper,U50 breakdown voltage of different gaps is obtained through tests to determine the appropriate distance of series gap.
