| 摘 要： | 笔者从线路设计角度进一步定性分析了单(或双分裂)导线覆冰舞动机理,指出使用现有抑舞装置应注意的问题:单导线(地线)耐张线夹和悬垂线夹的固定导线(地线)结构使固定点附近的单导线(地线)扭转刚度很大,易形成偏心覆冰并诱发舞动,进一步扩散至档内中央;绞制的导线单丝沿线不连续覆冰使单丝应力分布不均,以致导线内部不稳借助风力发生... |

| Abstract: | The mechanism of ice-coating and swing of single conductor or two-conductor bundle was analyzed for power transmission line design.It was found that in the existing anti-swing devices,the structures on strain clamp and suspension clamp for fixing single conductor(earth line) will lead to a large torsional rigidity in the earth line to form off-centered ice-coating,and further to induce swing which will spread to middle span.Discontinuous ice-coating on individual wire of twisted conductor may causes uneven ... |
