为改进变电站绝缘子带电清洗技术，得到安全高效、既可带电作业又不会出现污闪事故的变电站污秽绝缘子清洗方法，研究了一种利用绝缘介质干冰来清除绝缘子表面污秽物的方法。研究过程中建立了模拟试验平台，首先在干冰喷射距离、喷射角度、干冰流量、绝缘子表面污秽等不同参数下进行了清洗试验，分析了各参数对干冰清洗不同污秽及不同绝缘子效果的影响，得出了绝缘子采用干冰清洗的最佳参数范围，通过清洗自然积污和人工染污绝缘子进行了验证。试验表明，采用于冰清洗方法能很好的清洗绝缘子表面污秽，与其它方法相比，除污效率更高。

We put forward a method to remove pollution on insulator surface by dry ice in order to get a safe and effective way to clean the insulator surface. This method can be used to do live-line work without the risk of pollution flashover. To compare the performances under different conditions, an experimental platform is constructed. Moreover, effects of dry ice cleaning in the different parameters such as angles, distance, rate of dry ice flow, and different pollutions are compared and analyzed through experiments. Furthermore, the optimum combination of the parameters is determined, and the advantage of dry ice in insulator cleaning is verified by non-artificially and artificially polluted insulators experiments. The results indicate that dry ice cleaning can well work and has higher efficiency in insulator surface cleaning.
