Abstract

Abstract: In order to study the influence of pollution degree and humidity on the discharge characteristics of porcelain insulators in a fog room environment, this paper uses Comsol Multiphysics software to simulate the electric field distribution of clean and dirty insulators in a 110kV transmission line with or without a fog room. The results show that the electric field around the clean insulator in the foggy room becomes larger at the high-voltage side and the low-voltage side becomes smaller than that in the non-fog room; and the electric field around the insulator in the fog room becomes larger as the contamination increases.
