Electric Field Simulation of Helicopter Live Working with Platform Method for 1 000 kV UHV Transmission Lines

The development of helicopter live working technology is of great significance to improve the maintenance level of transmission line operation and maintenance. In order to further ensure the safety of helicopter live working for UHV transmission lines and provide technical basis for the live operation, this paper studies the electric field simulation method of helicopter live working for 1 000 kV UHV transmission lines. According to the actual parameters of MD 500 helicopters, operators and 1 000 kV triangular transmission lines, a helicopter live working model is established and put forward the simplified method. Based on the finite element static electric field simulation method, the impact of the factors such as the boundary area of the helicopter live working model and the position of the main rotor in the helicopter flight process is discussed, and the corresponding suggestions are given. Finally, the feasibility of the simulation method is verified by comparing the electric field data with the test site. The research results of this paper provide a reference for the simulation and test of the helicopter live working.
