500kV同塔双回直线塔挂线方式的研究

对现阶段国内同塔双回直线塔常用的导线排列方式和挂线方式进行经济技术分析,提出了一种500 kV同塔双回直线塔新型挂线方式———＂VIV＂方式。通过与传统采用的挂线方式进行塔重、占用走廊宽度及电气性能比较,证明该新型布置方案具有较大的优势。最后通过实际工程的应用,证实该新型布置方式在减少铁塔单基重量和节约线路走廊方面取得很好的效果,具有广泛的应用价值。

Line-hanging Research for Tangent Tower in 500 kV Double-circuit Lines on the Same Tower

It is proposed to use a new line-hanging method,named VIV,for tangent tower in 500 kV double-circuit lines on the same tower.Comparing the tower weight,the usage of the corridor width and the electrical performance of VIV method with those of traditional line-hanging methods,it proves that the new layout program has greater advantages based on economic and technical analyses.The practical engineering applications prove that the new layout method will reduce both corridor width and tower weight,so VIV has a ...
