摘 要: 及时掌握绝缘子表面污秽程度并采取措施能有效减少污闪事故的发生。介绍了泄漏电流法、等值盐密法、表面污层电导率法、污闪电压梯度法和脉冲电流法的电量监测方法以及微波辐射法、声发射监测法和红外成像监测法的非电量监测方法,并对它们的优缺点进行了分析。绝缘子发生污闪是温度、湿度、运行电压等多因素综合的结果,指出绝缘子污秽度监测研究方向,应建立多因素、多参量的综合性的监测方法。

Abstract: Timely detection of insulator surface filth degree and timely measures can reduce the accidents of pollution flashover. Introduction was made to the electric quantity monitoring methods including leakage current method, equivalent salt density method, surface filth layer conductivity method, pollution flashover voltage gradient method and pulse current method, together with the non-electric quantity monitoring methods such as microwave radiation method, acoustic emission monitoring method and infrared imaging monitoring method, and analysis was made to their advantages and disadvantages. Insulators turned up pollution flashover because of temperature,humidity, operational voltage etc synthetical factors. It is pointed out that the monitoring research direction of insulator filth degree should build up synthetic monitoring methods of comprehensive factors and parameters.
         Key words: insulator; filth; electric quantity monitoring method; non-electric quantity monitoring method
