| 摘 要： | 按规程所推荐的利用标准波实验得到的伏秒特性曲线和伏秒特性定义来判断绝缘子串两端雷电过电压的闪络情况,以其为基础进行防雷计算时,其计算结果与实际运行经验相差较大.介绍了先导发展法作为绝缘子串闪络判据,列出了三种不同的流注发展时间和先导发展时间的计算经验公式,并根据计算数据与实验结果的误差比对,选出最最适合作为绝缘子串闪络...

| Abstract: | According to the recommendation of regulation,the volt-time characteristic curve and definition acquired by standard wave experiment is applied to judge the flashover of lightning over-voltage at both ends of insulators.The result of lightning protection calculation on the basis of this method differs a lot from that of the actual operation.This paper introduces the criterion of insulation flashover based on antecedent development method,and lists three different functions of streamer development and antece... |
