摘　　要：分析了自挂式跳线和关联跳线、刚性跳线和软跳线的特点,指出对于1000 kV特高压线路使用的单柱组合耐张塔,无关联侧跳线以自挂式刚性跳线为好,对有关联侧跳线则推荐采用结构简单、造价低廉的关联型软跳线。因关联式软跳线具有承力的特点,故跳线系统的计算较为复杂;跳线串偏角和跳线对跳线串末端的张力是跳线计算的边界条件;对跳线串末端至耐张线夹之间的跳线可以按孤立档进行计算;跳线计算应寻求满足边界条件下的张力最小值,计算成果作为跳线施工数值依据。The characteristics of self-suspended jumpers,associated jumpers,rigid jumpers and soft jumpers were analyzed.It is pointed out that for the single-pole-combined strain towers used in the 1000kV UHV transmission line,the better selection for the jumper on the non-associated side is the self-suspended rigid jumper;and for the jumper on associated side,the associated-type soft jumper,which has simpler structure and lower cost,are recommended.Due to the load bearing characteristics of the associated soft jumpe...
