摘　　要：为了给输电线路防污闪提供科学指导,优化绝缘子污秽度预测特征量,从而提高污秽度预测可靠性,建立了唐山污秽试验站,选取环境温度、湿度、泄漏电流峰值、平均值以及脉冲次数,利用模糊数学方法建立并优化绝缘子污秽评价系统,得出的数据与现场实测数据有很好的一致性。In order to guarding against contamination flashover,it is important to improve the reliability of the monitoring system based on leakage current. By selecting temperature,humidity,peak value of leakage current,average value of leakage current and number of pulse current as the main parameters,optimization of the contamination evaluation system of insulator based on fuzzy method is realized in Tangshan natural contamination experiment station.The obtained data is consisted with that from onsite tests.
