特殊情况下跳线计计算及电气间隙检查

Jump Wire Calculation and Check of Air Clearances in Special Condition

结合工程实例,对“干”字型耐张塔中相绕跳采用单跳串加扁担线夹的组装型式进行了讨论和验算,得出了跳线对塔身的间隙满足电气要求的结论,不仅能安全运行,还能节约原材料,降低工程造价。

Combining with engineering real problem of middle phase line bypass jumping on a 'duplex F' shape strain tower, the erection mode-single jump string with carrying pole clamp was discussed and checked, and the conclussion that the air gap between such jump wire to tower body will meet the electric requirement, has been gotten. It can get safety operation, saving of raw materials and lowering of construction cost.
