摘　　要：输电线路绝缘子的长期积污并受潮而引起的污闪是电力系统安全运行的主要危害之一。研究绝缘子的积污特性可以了解绝缘子在不同气象条件下的积污状况并采取有效措施预防污闪事故的发生。通过人工积污试验和空气动力学特性仿真,得出了XWP2-160双伞型瓷绝缘子和FC160P钟罩型玻璃绝缘子在不同风速和风向影响下的积污特性以及流场分布特性,分析了影响绝缘子积污的主要因素。结果表明绝缘子背风面和迎风面是积污较大的区域,风速和风向对绝缘子积污有较大影响。FLUENT仿真与试验结果比较符合并能反映出绝缘子的积污特性。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 aerodynamic 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.
