输电线路绝缘子防污闪技术研究及预防措施

Research on Anti-pollution Flashover Technology of Transmission Line Insulator and its Preventive Measures

输电线路污闪是输电线路经常发生的故障,绝缘子是输电线路的重要组成部分,能够有效防止污闪故障的发生。文章首先对绝缘子污染来源进行详细分析,即大气污染、气候因素、环境因素、鸟粪污闪以及绝缘爬距及结构形状的影响,在此基础上,提出了输电线路绝缘子防污闪的几点措施:定期清洗或清扫,调爬,合理选用绝缘子,防污闪管理办法,在线监测绝缘。

Pollution flashover of transmission lines is a frequent accident of transmission lines, and insulators are an important part of transmission lines, which can effectively prevent the occurrence of pollution flashover accidents. Firstly, the sources of insulator pollution were analyzed in detail, including air pollution, climate factors, enviromnental factors, bird manure pollution flashover, insulation creep distance and structure shape.On this basis, this thesis put forward several measures to prevent pollution flashover of transmission line insulators： regular cleaning or cleaning, climbing adjustment, reasonable selection of insulators, pollution flashover management methods, on-line monitoring of insulation.
