污秽绝缘子闪络特性研究现状及展望

文章综述了几十年来国内外对污秽绝缘子闪络特性的研究状况,包括污秽绝缘子运行状态的表征方法、污秽绝缘子闪络电压与污秽或气压之间的关系以及尚未解决的问题。同时对未来绝缘子污秽特性的研究进行了展望,指出了污秽绝缘子人工试验方法、低气压、覆冰(雪)、酸雨(雾)等复杂环境下的长串绝缘子闪络特性、污秽等级划分的修订等是今后的研究重点。

Present Situation and Prospect of Research on Flashover Characteristics of Polluted Insulators

The research status on flashover characteristics of polluted insulators in recent decades, including methods to token the operation condition of polluted insulators, correlation among flashover voltage, pollution level and air pressure, and problems to be clarified are summarized. Meanwhile the prospect on the research of pollution characteristics of insulators in the future is described and the major research contents from now on, such as the artificial testing method of polluted insulators, the flashover characteristics of long string of insulators under the complicated conditions of low air pressure, ice or snow coating, acid rain or fog and the revision on pollution level, are pointed out.
