输电线路舞动概况及故障分析

我国是输电线路舞动灾害频发的国家,线路的舞动严重威胁电力生产的安全。本文总结了近两年输电线路覆冰舞动的总体情况以及线路舞动的故障特点,分析了形成原因、总结了目前常用的防舞措施。结果表明:导线的舞动主要由覆冰、风激励、线路结构和参数决定;采取避舞、抗舞和抑舞措施可有效防止舞动危害;最后指出了输电线路舞动研究中尚待解决的问题和进一步研究方向。

The Situation and Failure Analysis of Conductor Galloping on Transmission Line

Our country often occur conductor galloping of transmission line.Conductor galloping can seriously threat the safety of electric power transmission.This paper summarizes the overall situation and fault characteristics of conductor galloping in recently years,and analyzes the formative factors of conductor galloping,anti-galloping measures.The results show that the formation of conductor galloping mostly depends on icing,wind as well as configuration and parameters of transmission lines.The harm resulting form conductor galloping can be effectively avoided,resisted or restrained if some measures are taken.Besides,this paper puts forwards the problems in the research of conductor galloping and points out the orientation further investigation.
