摘　　要：由于煤矿井中含有大量的瓦斯粉尘,因此矿井电气设备用电的安全性是煤矿的一个关键问题。针对传统的无线供电系统的缺点,在综合考虑瓦斯粉尘对用电安全的影响的基础上,提出了一种煤矿井下电气设备无线供电系统,并给出了一种高瓦斯粉尘环境下考虑粉尘电导性的无线电能传输系统全互感模型建模方法,通过与纯互感耦合模型阻抗模频率特性进行对比分析,得出了全互感模型下系统的阻抗特性与理想的纯互感模型的区别,提高了模型建模的精确性,并得出了系统最优化谐振频率计算方法,最后通过仿真和实验验证了理论分析方法的正确性。Due to high gas dust existing in coal mine, the safety of electrical equipment power supply is a key problem to the coal mine. As wireless power transfer（WPT） technology solved the lack of traditional contact-type power supply methods, considering the electrical safety caused by high gas dust, a wireless power supply system applied to electrical equipment used in the coal mine was put forward, and a full mutual model considering dust conductivity was also pres- ented, in contract to the traditional mutual model by analyzing its frequency characteristic of the impedance modular, the difference between them was obtained, which has effectively improved the modeling accuracy. Finally, the theoreti- cal analysis was verified through simulation.
