摘　　要：输电线覆冰后在风载荷作用下舞动特性明显。在冻雨工况下,输电线会形成雨凇覆冰。而雨凇覆冰往往会造成严重电力事故,因此研究雨凇覆冰过程,对输电线安全运行有重要指导意义。首先分析了雨凇覆冰的形成过程及其影响因素,然后进行了雨凇覆冰的危害分析,其次总结了现有的雨凇覆冰预防措施,最后展望了雨凇覆冰的下一步研究方向。The galloping characteristic of the transmission line is obvious under the action of wind load after the transmission line is ice-coated.Under freezing rain conditions,rime icing will form on transmission lines and rime icing often cause serious power accidents.Therefore,studying the rime icing process has important guiding significance for the safe operation of transmission lines.Firstly,the formation process of rime icing and its influencing factors are analyzed.Then,the hazards of rime icing are analyzed.Thirdly,the existing preventive measures for rime icing are summarized.The effects of rime icing are summarized.Finally,the next research direction of rime icing is prospected.
