摘要
输电线路因地域跨度大,所处环境恶劣,使其成为受雷电、覆冰、大风、鸟害、污秽、地质等自然因素影响最为严重的设备,自然灾害导致线路故障的机理研究对于提高线路灾害防治技术以及安全运行具有重要的意义.本文阐述了国内外输电线路故障跳闸的主要原因,阐述了雷击、覆冰、大风、污秽、鸟害、地质灾害等导致故障的危害及特点,总结了各类自然灾害导致输电线路故障机理研究现状和进展,为防治各类自然灾害对输电线路基础性技术研究工作提供一定的参考.
Transmission lines are prone to lightning,icing,strong wind,and other disasters. The research on disaster mechanism and control technology is very important to improve the safe operation of transmission lines.The main reasons of the trip-outs of transmission lines in China are expounded in this paper.Hazards and characteristics of the main fault such as light-ning,icing,wind yaw,flashover,galloping,bird,external damage etc.are analyzed.The ad-vances in the disaster mechanism are discussed to present some reference to basic technical re-search on the prevention and control of natural disasters.
