[Abstract]:In order to improve the transmission power and efficiency of the underground radio energy transmission system and reduce the capacitance voltage of each loop, the structure of the coils of the underground radio energy transmission system is improved, and a transmission system suitable for the underground radio energy transmission is proposed.According to the circuit mutual inductance coupling theory, the mathematical expressions of transmission power and efficiency of radio energy transmission system are derived, and the effects of coupling coefficient and load on transmission power and transmission efficiency are discussed respectively.The influence factors of transmission system are simulated and analyzed by using OrCAD and Matlab software, and the experimental platform is designed and made on this basis.Experimental results show that the system has the best transmission distance, and the overall experimental results are consistent with the theoretical simulation results. Finally, the experimental results are compared with the typical three-coil magnetically coupled resonant radio transmission system.It is concluded that when the transmission distance is the same, the improved three-coil magnetically coupled resonance radio energy transmission system not only improves the transmission efficiency but also increases the transmission power, which can provide a theoretical reference for the actual underground radio energy transmission system.
