摘要

针对750 kV同塔双回线路杆塔高、横担尺寸长、上中下三相导线垂直排列布置复杂，对带电作业人员要求高、登塔爬线难度大等问题，研究机械智能辅助相间带电作业技术可行性是十分必要的。文中选取750 kV同塔双回线路的典型塔型和导线布置，建立真型无人机、杆塔和导线的三维仿真模型，计算表明无人机从2 m到0.5 m接近导线抛绳作业时，对导线周围电场影响不大，加大了无人机自身周围电场，理论上此时无人机表面仍然没有起晕，无人机抛绳作业是安全可行的。并且实际测试验证了无人机抛投绝缘绳结合电动升降装置辅助人员进出等电位作业是可行的，为750 kV同塔双回线路智能辅助带电作业的开展提供理论参考。

Abstract

In view of such issues as high tower height

long cross arm size

complex vertical arrangement of upper

middle

and lower three-phase conductors

high requirements for live working personneland high difficulty in climbing towers and lines for 750 kV double-circuit transmission line on the same tower

it is highly necessary to study the feasibility of phase-to-phase live working technology assisted by mechanical intelligence. In this paper typical tower type and wire layout of a 750 kV double circuit line on the same tower is selected and a three-dimensional simulation model of the true type drone

tower

and wire is set up. The calculation shows that when the drone approaches the wire rope throwing from a distance of 2 m to 0.5 m

the impact on the electric field around the wire is not significant

and the electric field around the drone itself is increased. Theoretically

no corona occurs on the drone surface at this time

indicating that the drone rope throwing operation is safe and feasible. In addition

the actual testing has verified the feasibility of drone throwing insulation ropes combined with electric lifting devices to assist personnel in entering and exiting equipotential operations

providing theoretical reference for the intelligent assisted live working of 750 kV double-circuit lines on the same tower.
