摘要

在1:1模拟导线-杆塔间隙结构下

试验研究了不同雨强和雨水运动路径对空气间隙工频闪络特性的影响

得出不同雨强和雨水运动路径下导线-杆塔空气间隙工频闪络特性的变化规律。提出强降雨情况下满足间隙工频耐受电压高于500 kV输电线路最高运行相电压的最小空气间隙距离

为现场防风偏放电和输电线路设计提供理论指导。

Abstract

Using a simulated 1∶1 construction of transmission line and tower

the effect of rain with different intensities and paths on power frequency flashover of air-gap between the transmission line and tower was investigated

and the features of power frequency flashover of the air gap were obtained for different intensities and paths of rain.Therefore

the minimum air gap distance is proposed to withstand the maximum power frequency phase voltage of a 500 kV transmission line.This study would provide guidance to the design of transmission line and prevention of discharge caused by windage yaw in the field.
