摘要
输电线路覆冰是一种严重的自然灾害,可引发输电线路过荷载、导线舞动、绝缘子串闪络等事故,严重危害电力系统的安全运行。总结和分析了国内外输电线路典型覆冰事故、覆冰的种类与性质、影响覆冰的因素、绝缘子冰闪特性的研究以及输电线路覆冰机理的研究。分析结果表明:绝缘子覆冰闪络问题日渐突出;影响绝缘子覆冰的因素很多,其中电场对绝缘子覆冰的影响不容忽视。
Icing of transmission lines is a kind of serious natural disasters,which may cause many accidents such as transmission lines overloading,conductor waving,and flashover of insulator strings.It is great danger to the electrical power system security.An analysis and summarizes about the international typical accidents,the types and properties of icing,the influence factors about icing on transmission lines,characteristics about flashover of iced insulators and principle about icing on transmission lines are taken.The results show that the problem of insulator icing flashover become more and more serious;there are lots of factors can influence insulator icing,and field is an important factor which cannot be ignored.
