Research on Flashover Breakdowns and Prevention Measures of Synthetic Insulator of overhead Power Transmission Line

摘要

As an anti-pollution flashover facility, synthetic insulator is now widely used in the overhead transmission lines in China. It has good mechanical properties, nice anti-pollution flashover performance, strong electrical erosion resistance and high efficiency advantages in operation. However, the lightning, the bird, icing, filth, foreign body and other unknown reasons of flashover fault will influent the safety of overhead transmission lines. Therefore, it is important to improve the safety operation of the overhead transmission line.
