摘　　要：分析了煤矿井下对无线电能传输的需求,研究了微波、电磁感应、磁耦合谐振3种无线输电技术的特点及其在煤矿井下的适用性,认为磁耦合谐振无线输电技术可用于煤矿井下;重点分析了不同材质的障碍物对磁耦合谐振无线输电系统传输效率的影响,采用HFSS三维电磁仿真软件搭建了磁耦合谐振无线输电系统仿真模型,分别采用金属障碍物和非金属障碍物进行实验研究,结果表明非金属障碍物对磁耦合谐振无线输电系统的传输效率没有影响,金属障碍物则会降低系统传输效率,且增加金属障碍物厚度或侧面积会加大影响程度。Requirements of coal mine underground were analyzed for wireless power energy transmission. Characteristics of three kinds of wireless power transmission technologies were researched including microwave type, electromagnetic induction and magnetic coupling resonant type as well as their applicability in coal mine underground. It was considered that magnetic coupling resonant type wireless power transmission technology could be applied in coal mine underground. Impacts of different obstacles were analyzed emphatically on transmission efficiency of magnetic coupling resonant wireless power transmission system. A simulation model of magnetic coupling resonant wireless power transmission system was built by using HFSS 3D electromagnetics simulation software, and simulated experiments were carried out using metallic obstacles and the nonmetallic ones. The experimental results show that nonmetallic obstacles have no influence on transmission efficiency of the system, and metallic obstacles reduce transmission efficiency, especially in condition of adding thickness or reducing lateral area of the metallic obstacles.
