架空输电线路北斗定位弧垂观测研究

弧垂控制是架空输电线路紧线施工的关键技术,传统观测弧垂的方法制约因素较多、效率低、人为误差大,质量缺陷时刻威胁着输电线路的安全运行。尤其是在山区,长期存在的云雾天气使能见度极低,传统仪器经纬仪失效,严重制约工程进度。基于此,文章结合实际工程,对架空输电线路北斗定位弧垂观测进行研究分析。

Sag control is the key technology of overhead transmission line tightening construction.The traditional sag observation method has many restrictive factors,low efficiency,large human error,and quality defects threaten the safe operation of transmission lines all the time.Especially in the mountain areas,the visibility of the long-standing cloud weather is very low,and the traditional instrument theodolite is invalid,which seriously restricts the progress of the project.Based on this,taking real projects as examples,the sag observation of Beidou positioning on overhead transmission line is studied and analyzed in this paper.
