输电线路防冰除冰技术的研究与发展

Research and Development of Anti Icing and De Icing Technology of Transmission Line

输电线路覆冰是一种严重的自然灾害,可引发输电线路导线舞动、绝缘子闪络等事故,严重危害电力系统的安全运行。文中总结分析了输电线路覆冰的种类、性质及其影响因素,列举了现有的线路覆冰防治对策、除冰方法及除冰发展趋势,对以后线路设计抵御冰害提供参考,从而减少输电线路自然灾害带来的损失。

Transmission line icing is one of the serious natural disasters,cause galloping of transmission line or insulator flashover accident,which seriously endangers the safe operation of power system.The types,properties and the influence factors of transmission line icing is summarized and analyzed in this paper,the existing control strategies of ice cover and the existing deicing methods and the future development trend of deicing are listed.Therefore,this paper can provides reference for the future design of the line to resist ice damage,which reduces the loss of natural disasters of transmission lines.
