浅析输电线路绝缘子的防污维护相关技术

Brief Analysis of Antifouling Maintenance Technology of Transmission Line Insulators

长时间以来,输电线路暴露在野外,其正常运行常常受到大气与气候条件的影响,屡屡因输电线路绝缘子污秽导致污闪事故,造成输电线路故障跳闸或停运,给线路运行带来不良影响。本文对输电线路绝缘子污闪产生的原因进行了分析,介绍了国内通用的输电线路绝缘子防污维护技术,提出了输电线路绝缘子防污的主要对策。

For a long time,transmission lines have been exposed to the field,and their normal operation is often affected by atmospheric and climatic conditions.Pollution flashover accidents are often caused by polluted insulators of transmission lines,resulting in tripping or outage of transmission lines,which has adverse effects on the operation of transmission lines.In this paper,the causes of pollution flashover of transmission line insulators are analyzed,the common anti-pollution maintenance technology of transmission line insulators in China is introduced,and the main countermeasures for anti-pollution of transmission line insulators are put forward.
