Abstract
With the continuous progress of wireless power transfer (WPT) technology in the field of high-voltage (HV), this paper proposes a novel magnetic coupling mechanism fixed on the metal fittings at both ends of 500 kV insulator, which can further enhance the coupling between coils to provide stable electric energy for the online monitoring equipment on the HV tower. Firstly, suitable topological structure and coil parameters are selected for WPT system with long distance and small load. Then, the circular mesh magnetic coupling mechanism that acts as a fixed support is designed, and the finite element model is established. According to the simulation results, factors such as mutual inductance and volume are comprehensively analyzed to optimize the framework and ensure that it has no adverse effect on the original HV system. Finally, in order to prove its applicability, the performance of the designed coupling mechanism is analyzed under harsh environment of ice coating. It can be proved that the mechanism proposed is valid for WPT system on HV transmission lines, and several points for attention in monitoring and repairing HV system are offered.
