摘要
常规设计的线路换位塔应用在沿海强台风区时,跳线容易发生风偏闪络故障,针对此问题,通过优化塔头尺寸和引入鼠笼式刚性跳线,设计的换位塔可以抵御风速56.8 m/s(3 s时限平均风速)的超强阵风。
Flashover on the jumper caused by windage yaw is more likely to happen if the conventional transposition tower is adopted in coastal strong-typhoon area. To solve this problem, squirrel-cage rigid jumper and opti- mized tower head are adopted in transposition design, by which the transposition tower can withstand the superstrong gust with the speed of 56.8m/s （average wind speed within 3s）.
