摘要
Abstract
It is expensive and wasted that arresters were widely installed for 500 kV transmission line.To solve this problem,a way has been proposed.By lightning distribution,the site survey and theoretical calculations,the shielding failure rate of transmission line is calculated.Then arranging sites of arresters could be chosen in accordance with the values of shielding failure rates.A fine-tuning device of gas gap is designed for the arrester.Arresters with series gaps have been fitted in North China for the first time.It is proved that the improved electrogeometric model is valid.It is reasonable arranging arresters of 500 kV transmission line by this way.关键词
