得出不同雨强、雨水电阻率和雨水运动路径下导线-杆塔空气间隙工频击穿特性的变化规律。有关结论可为现场防风偏放电和输电线路设计提供依据。

Abstract

It is important to study the air-gap breakdown characteristics between conductor and tower in rainy weather for improving the reliability of high voltage power grid.In this paper

the breakdown characteristics were studied through artificial simulation test

and the relationships among breakdown voltage and some factors

such as rain intensity

rainwater resistivity

and drop direction were investigated

and the corresponding results were obtained.This study would be helpful for design and maintenance of transmission line against rainy weather.
