【摘要】：为提高煤矿井下无线电能传输系统的传输功率和效率,并降低各回路电容电压,改进了井下无线电能传输系统线圈的结构,提出了适合井下无线电能传输的传输系统。根据电路互感耦合理论,推导出无线电能传输系统的传输功率和效率的数学理论表达式,分别阐述了耦合系数和负载大小对传输功率与传输效率的影响。应用OrCAD与Matlab软件对传输系统各种影响因素进行仿真分析,在此基础上设计并制作了实验平台。实验得出此系统存在最佳效率传输距离,总体实验结果与理论仿真结果一致,最后通过与典型三线圈磁耦合谐振无线电能传输系统做对比实验分析,得出在井下相同传输距离时,改进三线圈磁耦合谐振无线电能传输系统在提高传输效率的同时也提高了传输功率,可为实际井下无线电能传输系统提供理论参考。
[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.
