Abstract
Aiming at the difficulty of power supply for online monitoring equipment (OME) of transmission lines and towers, a long-distance high-efficient wireless power transfer (WPT) system based on a new relay structure is designed in this paper. The transmission power and transmission efficiency (TE) are improved, which meets the continuous and stable power supply of OME. Combined with the limitation of 110 kV line on the transmission distance (TD) and size of WPT, the influence of the relative position of relay coil (ReC) on transmission performance is studied and summarized. The optimal position of ReC and the physical size of the magnetic coupling mechanism (MCM) are established. The effects of TD and DC voltage on the transmission performance of typical and new WPT are compared and tested. TE of new WPT is increased by about 20%. The proposed new MCM will provide a reference for the design and application of WPT on OME.
