| 摘 要： | 对输电线路进行测量时,当观测档处于复杂地形的特殊环境中时,由于在观测档内不能直接竖立棱镜,因而无法用常规的方法观测架空输电线路弧垂,这给测量工作带来困难。针对特殊环境中不同类型杆塔组合的常用设计方案的架空输电线路弧垂观测进行了探讨,并给出了一种测量方法及推导其计算公式,用以指导输电线路弧垂观测。

| Abstract: | When measuring the overhead transmission line,if the sag between two neighbour towers or poles is in a special environment with complicated terrain,the normal way can not measure the sag of transmission line since prism can not be setup.It makes difficulty to measurement.Based on usual designs of poles and towers combination of different types in the special environment,the observation and measurement of transmission line sag is discussed.A measuring method and its calculation formula are presented to guide... |
