Abstract
针对架空输电线路日常运维需求，本文从线路走廊地势地形、空域管理以及现有无人机技术等多因素进行分析，并在北京主网架空输电线路中的人工巡视无法到位、故障点核实、超期未登检线路开展小型旋翼无人机巡检。无人机巡检能够及时发现各类缺陷及隐患，有效地弥补了人工巡检不足，提高了线路运维效率。 According to the needs of daily operation of overhead transmission line, this paper analyzes the factors such as line corridor topography, airspace management, unmanned aerial vehicle (UAV) technology and so on, and inspection of small rotor UAV was carried out in artificial patrol im-possible lines, fault verification and extended inspection line of the main transmission line in Beijing. UAV patrol inspection can find various defects and hidden dangers in time, effectively make up for the shortage of manual inspection and improve the efficiency of line operation and maintenance.
