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.
Highlights
The reliability, stability and power supply quality of electric energy play a vital role in national economic development [1]. my country's transmission lines cover a wide range and the terrain is complex, which poses greater challenges for its normal operation, inspection and maintenance
The traditional manual maintenance method has high intensity, long cycle and low efficiency, and it is difficult to carry out maintenance work in some areas with complex terrain or even dangerous
Literature [10][11] mainly studies the impact of UAVs on the electric field around transmission lines and the safety distance between UAV inspection systems and transmission lines
Summary
The reliability, stability and power supply quality of electric energy play a vital role in national economic development [1]. my country's transmission lines cover a wide range and the terrain is complex, which poses greater challenges for its normal operation, inspection and maintenance. Compared with the traditional maintenance methods, the maintenance system of the UAV equipped with the robotic arm has the advantages of high efficiency, good operability and flexibility, less restricted by the terrain, and reduced casualties [2][3]. Literature [4][5] mainly studies the safety distance measurement method in the patrol inspection of UAV transmission lines. Literature [10][11] mainly studies the impact of UAVs on the electric field around transmission lines and the safety distance between UAV inspection systems and transmission lines. There are relatively few researches on the safety distance of the unmanned aerial vehicle equipped with robotic arm to repair power transmission lines. A test platform for the safe distance of power transmission lines with drones equipped with robotic arms was built, and the minimum safe distances for power transmission lines with drones equipped with robotic arms were obtained
