面向架空输电线路的挂载无人机电力巡检技术研究综述

Review on Mounted UAV for Transmission Line Inspection

无人机是巡检作业最理想的搭载工具,通过无人机挂载光学相机、红外成像、激光雷达等载荷装置对导线、绝缘子、金具等输电设备进行巡检工作已成为架空输电线路不可或缺的日常运维手段。该文首先介绍挂载无人机巡检技术的应用现状,系统论述挂载无人机巡检作业的工作模式;然后从无人机续航时间、无人机巡检作业安全距离和无人机电磁干扰防护等方面对挂载无人机电力巡检的关键技术进行重点综述;最后对挂载无人机巡检技术的发展趋势进行讨论,旨在为无人机电力巡检技术的研究提供方向。

Unmanned aerial vehicle(UAV) is the most ideal tool for transmission line inspection. By being mounted with the optical cameras, the infrared imaging technology, the lidar and other devices, a UAV has become an indispensable measure for overhead transmission lines inspection, checking the wires, insulators, electric power fittings and other power transmission equipment. This paper first introduces the application status of the mounted UAV for transmission line inspection. The working pattern of the mounted UAV for transmission line inspection is systematically discussed. In addition, some key technologies of the mounted UAV for transmission line inspection are emphatically reviewed, such as its endurance, the safe distance for inspection, its anti-electromagnetic interference design, and the like. Finally, the development trend of the mounted UAVs for transmission line inspection is concluded, aiming to provide some useful references for related researches.
