Research on Electric Field Safety Distance of High-Voltage Equipment in Substations Inspected by UAV

UAVs have the advantages of close observation, eliminating visual dead space, improving inspection speed and carrying a variety of inspection equipment in substation equipment inspection, which meet the needs of intelligent substation construction. But the complex electromagnetic environment in the substation, it is easy to cause electromagnetic interference to the UAV, while the UAV into the strong electric field environment there is also the possibility of triggering discharge. In this paper, we take the Genie 4 UAV commonly used for substation inspection as the research object, and study the safety distance when the UAV inspects the high-voltage equipment in the substation. By constructing the simulation model of the UAV and 220 kV substation, we simulate and calculate the electric field distribution when the UAV inspects different high-voltage equipment. Finally, the safety distance of the UAV inspection of high-voltage equipment in substations is analyzed by the simulation results, and provides data support for the subsequent research.
