| 摘 要： | 1000 kV特高压同塔双回输电工程中,有关联双柱组合耐张塔采取软跳线方式可取消其跳线横担,减小塔身尺寸和杆塔呼称高度,降低工程投资。分析了有关联双柱组合耐张塔软跳线的特点以及跳线串悬垂角、软跳线张力的计算方法。以1000 kV淮南—上海特高压同塔双回输电工程为例,计算了4种型号的有关联双柱组合耐张塔的跳线串悬垂角、软跳线张力,结果表明常规跳线线夹已不能满足要求,建议专门研制超高压软跳线线夹。

| Abstract: | The double-pole-composite strain tower used for 1 000 kV UHV 1-tower double-circuit transmission line project adopts flexible jumpers and cancels the jumper crossarm,which reduces the tower size and nominal height,and engineering cost.The paper analyzed the strain tower jumper characters,jumper string suspension angle and soft jumper tension calculation.Taking the 1 000 kV 1-tower double-circuit transmission line from Huainan to Shanghaias an example,the paper calculated the flexible jumper tension and decl... |
