无人机检修作业已成为架空输电线路日常运行维护的重要手段。当检修系统接近线路作业时,高电压、大电流、强电磁环境均容易对系统造成破坏。基于35 kV交流输电线路直线塔检修作业的实际工况,提出了一种基于机械臂的无人机检修作业系统设计方法,建立了35 kV输电线路无人机检修作业有限元模型,主要研究了输电线路周围电场对所设计系统的影响,最后搭建了35 kV线路无人机检修作业真型试验平台对系统进行加压测试。仿真与试验结果表明,检修作业系统能够满足35 kV架空输电线路的检修技术要求。该研究成果可为35 kV输电线路多旋翼无人机检修作业系统的相关部件设计与防护提供技术保障。

Unmanned aerial vehicle(UAV)inspection has become an important means for daily operation and routine maintenance of overhead transmission lines.When the inspection system is in contact operation,the high voltage,high current,and strong electromagnetic environment are easy to cause damage to the system.Based on the actual parameters of typical 35 kV AC transmission lines and intermediate towers,this paper proposes a design scheme of the UAV inspection system based on mechanical arm.Moreover,the finite element model of UAV inspection system was established.The influence of electric field around the transmission line on the designed system was mainly studied.Finally,a test platform of UAV inspection system for 35 kV transmission line was built to carry out pressure test on the system.The results of simulation and test show that the working parameters of the prototype system adapt the design requirements.What's more,it can fit the technical requirements for the inspection of 35 kV high-voltage overhead transmission lines.The research results can provide technical supports for the design and protection of relevant components of the multi-rotor UAV inspection system on 35 kV transmission lines.
