摘要

500 kV线路避雷器成本高

大面积安装造成资源浪费。针对此问题

提出了应用电网雷害分布

经过现场勘测和理论计算

得出绕击跳闸率高的杆塔作为安装点。根据空气间隙避雷结构特点

设计了空气间隙微调装置

并在华北地区首次挂网运行。运行结果证明了理论计算的有效性以及线路避雷器布置的合理性。

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.
