Research on the Safe Distance of UAV Carrying Manipulator for Inspection and Repair of Transmission Line

Abstract

When the drone is equipped with a robotic arm to replace the manual maintenance of the transmission line, the insulating parts in the drone maintenance system are prone to discharge and breakdown risks. In this paper, combined with the actual parameters of the transmission line and the UAV maintenance system, the finite element software is used to establish the electric field simulation model of the transmission line and the UAV maintenance system, and mainly analyzes the influence of the electric field around the transmission line on the UAV maintenance system at different distances. It is concluded that the distance between the overhaul system of the drone equipped with a robotic arm is greater than or equal to 0.02m, and there is no discharge breakdown of the insulation components; and the drone is carried out by building a test platform for the drone equipped with robotic arm to overhaul the transmission line. The safety distance test study of the robotic arm overhaul system shows that the safe working distance of the insulated components of the drone equipped with robotic arm overhaul system is 0.09m. This research provides a guarantee for the safe operation of the power transmission line equipped with the robotic arm overhauled by the drone in actual scenarios.
