Abstract:
The spatial potential and electric field distribution of clean insulator and insulator with different degrees of pollution in 110kV transmission lines are analyzed with Comsol Multiphysics software. The results show that: The curve connected by the voltage borne by the single piece insulator in the clean insulator string is saddle-shaped. The voltage borne by the high-voltage end and the low-voltage end is large, while the voltage borne by the middle part of the insulator string is small. With the increase of pollution degree, the overall trend of potential distribution remains unchanged, but the higher the pollution degree is, the greater the maximum voltage on the high-voltage side of the insulator will be, and the smaller the minimum voltage on the low-voltage side will be. With the increase of pollution degree, the general trend of electric field distribution around insulator string remains unchanged, but the maximum value of electric field increases.
