| 摘 要： | 输电线路在风的作用下会发生振动甚至舞动,导致输电塔线体系倒塌,造成严重的输电线路事故;分析不同情况下风速、风向对输电线路舞动的影响,提出可采用水平布置导线的方式,确定导线的水平相间距离远大于导线舞动的水平方向位移,即可防止导线问发生碰线闪络,提高导线的防舞动能力;另外,通过加装防舞动装置也可防止输电线路发生舞动,保证输...

| Abstract: | Transmission lines may vibrate or gallop due to wind load,which may cause collapse of poles and towers for power transmission and severe accidents of transmission lines.The paper analyzes impact of wind speed and direction on transmission line galloping under different conditions,and it recommends adopting horizontal wire arrangement and making horizontal phase distance greater than horizontal displacement by wire galloping,which could prevent flashover among wires and improve anti-galloping capability.Besi... |
