摘　　要：对架空输电线路进行弧垂测量,如果观测档处于复杂特殊环境中,此时在地面无法直接竖立测量仪器进行测量,常规方法不再适用,给测量工作带来困难。文章针对这种特殊跨越状况,提出采用等电位带负荷进行测量的方法,对方法进行推导验证,并利用集中参数下弧垂计算公式对该方法进行修正,同时对等电位作业过程中相关技术参数及安全注意事项加以说明。结论说明该方法较集中参数下的理论计算方法简便得多,相对传统测量方法更加方便,特别适用于施工现场测量弧垂。If the observation crosspiece is in a complex environment when we do the sag measurement of overhead transmission lines, the measuring instruments can not be erected directly for measurement. Then the conventional methods are no longer applicable which will make the measurement more difficult. For this particular situation, a method of equipotential measurement with load is put forward, and the sag formula with lumped parameter is taken to modify the method. Simultaneously, some related technical parameters and safety precautions are illustrated during equipotential operation process. It is clear that this method is much simpler compared with the theoretical calculation method of the lumped parameter, and is more convenient compared to traditional measurement methods, especially suitable for sag measurement at the construction site.
