The Potential Distribution of Icing Insulators

Abstract:

The phenomenon of icing on insulators was common in power system, therefore, the research on insulator potential of different icing length is meaningful for clearing the ice on insulators. 110kV non-ceramic insulator (FXBW-110/120) was taken as an example, the model based on finite element static electric field is built in ANSYS to analyze the effect on potential distribution of insulator surface based on different icing length. The result shows that: the potential of clean non-ceramic insulator is not well distributed, surface potential of insulator is not affected greatly when icing length is below 60cms; The end potential of insulator is greatly changed when the icing length is up to 70cms; The whole surface potential of insulator is changed and insulation capability is droped obviously when the icing length is up to 80cms.
