高电导率雾对悬式瓷质绝缘子交流闪络特性的影响
Influence of High Conductivity Fog on AC Flashover Characteristics of Suspension Porcelain Insulator
摘要
Abstract
In order to study the effect of high conductivity fog on AC flashover characteristics of the contaminated insulator,we simulated the process of pollution getting wet of the XP10-16 suspension porcelain insulator by solid coating method and high-pressure micro-fog humidification method in the artificial climate chamber,and obtained the relation curve of insulator flashover voltage and the salt density or the fog conductivity by the up-and-down method.Research resuits show that insulator's flashover voltage decreases with the increase of the fog conductivity,and the influence of the fog conductivity is more remarkable when the salt density value is low,and the fog conductivity can be affected additional salt density coefficient.After the distribution of electric field in space of the insulator is calcultaed under different the fog conductivity values by Comsol Multiphysics software,it is concluded that high-conductivity fog mainly influences the flashover voltage of insulator by changing the degree of pollution on insulator surface.关键词
