Transmission Characteristics of Multi-Resonant Coils Based on Finite Element Method
摘要
Abstract
Power supply for online monitor equipment of transmission towers is crucial to ensure the safety and reliability of transmission corridors.Packaging coils inside insulators for wireless power supply is one of the effective ways to solve the above problem.However,most research focuses on wireless energy transmission for short distance and one resonant coil,lacking research on long-distance and multi-res-onant coils.Based on finite element method(FEM),the author conducts the simulation on transmission characteristics of multi-resonant coils.Results show that the multi-resonant coil FEM model in this pa-per can effectively simulate their energy transmission performance,with an error within 10％compared to experimental results.With the increase of frequency,the transmission efficiency shows a"wave-like"growth near the resonance frequency.As the coil spacing decreases,the transmission efficiency basically increases at equal amplitude,and with the increase of coil outer diameter,the transmission efficiency is significantly improved,but with the increase of outer diameter,the growth rate of transmission efficiency gradually decreases;as the load increases,the maximum efficiency first rises and then declines,while the corresponding frequency shifts toward the high frequency.Overall,the outer diameter of coils has a more significant impact on transmission efficiency than coil spacing.关键词
