摘要
表征复合绝缘子老化情况的一个重要判据是其污闪电压的变化 ,然而电力运行部门一般并不具备污闪试验的条件 ,笔者介绍了评估运行中复合绝缘子质量的一些其它参数 ,分析了老化后复合绝缘子表面微观结构的变化。
Although the pollution flashover voltage is an important criterion for judging the aging condition of composite insulators in operation,most electric power utilities are not able to carry out such tests in their high voltage laboratories. The author introduces some other parameters, which can be used to evaluate the quality of composite insulators,and analyses the changes in the surface microstructure of aged insulators.
