摘要:

电力系统运行中,高压输电线路绝缘子污闪是一种常见的事故,其对于输电线路的安全运行以及电力系统安全运行有着非常重要的影响。随着输电线路的防污闪技术研究不断深入,清扫积污、调整爬电距离、使用防污闪涂料、采用复合绝缘子等技术应运而生。其中复合绝缘子以其优良的抗污特性,被广泛应用于防污闪技术中。本文综述了绝缘子污闪的机理、输电线路防污闪措施、合成绝缘子结构特点、优良性能,及在其使用过程中的常见问题。

In the operation of power system, insulator flashover is a common accident which has serious effect on high voltage transmission line. Some methods, such as cleaning contamination, creepage distance adjustment, using anti-flashover coating and using composite insulators, have been emerged with the development of anti-flashover technology. Among those methods, the composite insulators were widely used because of its excellent stain resistance characteristics. This paper reviews the mechanism of flash insulator pollution, measures of anti-flashover, structural characteristics and excellent performance of composite insulators. Finally, frequently asked questions in the course of its use were discussed.
