雨水路径和电极结构对导线杆塔空气间隙工频闪络电压影响研究

The Research on the Affection on the Flashover Voltage at Power Frequency of the Air-gap Between Conductor and Tower Caused by Raining Direction and Electrode Pole

对不同雨水运动路径和电极结构对导线-杆塔空气间隙工频闪络电压影响进行试验研究,得到其放电特性曲线,分析了间隙的放电规律和特点,确定了不同雨水运动路径和电极结构下的放电间隙距离,为现场防风偏放电和输电线路设计提供理论指导。

In this paper,the affection on the flashover voltage of the air-gap between conductor and tower caused by different raining moving direction and the construction of electrode pole was studied.The relative curves of flashover voltage were got from series of tests, the character of the flashover voltage of the air-gap were analysed according to the tests, to ascertain the distances of flashover gap at different cases of raining moving direction and electrode pole.It was directive for defending flashover caused by windage on site and as a reference for transmission line designing.
