特高压输电线路巡检无人机安全技术研究

Research on Safety Technology of Unmanned Aerial Vehicle for UHV Transmission Line Inspection

随着特高电网建设的推进,无人机在特高压输电线路巡检中的应用越来越广泛,从而提高巡检工作的效率。无人机在巡检过程中会受到导线周围感应电磁场的干扰,造成无人机失控,威胁电网设备安全。采用电磁波阻隔技术、多余度飞行控制系统以及无人机避障技术,可以提高无人机在特高压输电线路巡检工作中的安全性。

With the development of UHV grid,Unmanned Aerial Vehicle(UAV)has been more and more widely used in UHV transmission line inspection,thus improving the efficiency of inspection.During the inspection,the UAV will be disturbed by the electromagnetic field around the wire,causing the UAV out of control and threatening the safety of power grid equipment.The safety of UAV in UHV transmission line inspection can be improved by using electromagnetic blocking technology,redundant flight control system and UAV obstacle avoidance technology.
