输电架空线路的受力磨损特性

Force and Wear Characteristics of Overhead Transmission Lines

随着社会的不断发展,整个社会用电量急剧增加,用电负荷呈现扩张趋势,电力在生产生活中发挥前所未有的巨大作用。目前,架空输电线路是主要线路模式,其中,发挥关键性作用的是导线。但是,鉴于行业限制,架空导线多处于室外环境,深受风力等多因素的影响,使得导线线股以及导线与线夹之间磨损现象出现,存在不可避免性,长此以往,就会影响导线自身性能的发挥,造成多种不良问题。因此,要结合实际,深入分析输电架空线路的受力磨损特征,形成针对性应对方案,在根本上保证整个输电架空线路的稳定运行。

With the continuous development of society,the electricity consumption of the whole society has increased dramatically,and the electricity load has shown a trend of expansion.At present,overhead transmission lines are the main mode of transmission.However,in view of the industry constraints,overhead conductors are mostly in the outdoor environment,deeply affected by wind and other factors,making the conductor strands and between conductor and clamp wear phenomenon,there is inevitability,in the long run,it will affect the performance of the conductor itself,resulting in a variety of adverse problems.Therefore,it is necessary to analyze the wear and tear characteristics of overhead transmission lines in depth and form corresponding solutions to ensure the stable operation of the whole overhead transmission lines.
