摘要

绝缘子污闪造成的事故严重威胁着电力系统的安全运行。在实际运行的线路中

由于周围环境污染

积污绝缘子表面在自然雾中受潮

绝缘性能下降

易引发污闪事故。在表征绝缘子污秽度的特征量中污层电导率是一个非常好的参量

研究影响绝缘子污层电导率的因素具有重大意义。笔者以XP-70、XP-160和LXY4-160绝缘子为研究对象

通过人工污秽试验分析了不同盐密、污秽成分和绝缘子型式对污层电导率的影响。结果表明:随着盐密的增大

污层电导率也逐渐增大;当盐密一定时

污层电导率值随着污秽成分中NaCl比例的减小而减小;绝缘子的形状结构对污层电导率值几乎没有影响。

Abstract

The accident caused by insulator pollution flashover is a serious threat to the safe operation of power system. In the actual operation of the line

due to the surrounding environment pollution

the contamination layer on insulator surface gets wetting in natural fog and is easy to cause the pollution flashover accidents. SPLC is a very good characteristic quantity to measure pollution degree

so the study on influence factors of SPLC is of great significance. Based on the XP-70

XP-160 and LXY4-160 standard insulators as research object

by means of artificial pollution test

the SPLC under different SDD

contamination component and insulator type are measured. The results show that

with the increase of SDD

the SPLC is gradually increases; when the SDD is constant

with the decreasing of NaCl ratio the SPLC is decreasing; the shape of insulator has almost no effect on SPLC.
