Study on pollution accumulation characteristics of typical insulators

Pollution flashover caused by long-term contamination and moisture of the transmission line insulators is one of the main dangers for the safe operation of the power system. To study the contamination characteristics of the insulators in different weather conditions enables us to understand the contamination conditions of the insulators and take effective measures to prevent the pollution flashover accidents. Through the artificial contamination test and air dynamic simulation of the XWP2-160 double-shed insulator and FC160P glass insulator, it is concluded the influence of pollution contamination characteristic and flow field distribution characteristic in different wind speed and wind direction. The main factors that affected the insulator contamination characteristic were also analyzed, which can provide some guidance to the configuration of transmission lines insulators and antifouling work.
