摘　　要：结合电路理论,在电工测量实验教学中开展了基于磁耦合谐振无线电能传输原理的分析与研究。利用自制耦合线圈,开发了一套无线电能传输实验系统及装置,可实现30cm范围内向负载灯泡无线供电,并据此提出一项新的综合性实验方案。结果表明,该实验系统传输效果及波形数据较好,可直观反映无线电能传输规律及特征,实验结果与理论分析一致。将其应用于实验教学中,既能强化学生对交流电路知识的理解,提高其实践动手能力和初步电路设计能力,而且能让学生认识电路理论的工程实际作用。Combined with circuit theory,we analyze and research the principles of magnetic coupling resonance radio energy transmission in electrical measurement experimental teaching.On this basis,a radio energy transmission experimental system and device are designed and developed using selfmade coupling coils.A new comprehensive experimental content is proposed to achieve wireless power supply to load bulbs within a range of 30 cm.The results indicate that the transmission effect and waveform data of the experimental system are ideal,it can intuitively reflect the laws and characteristics of radio energy transmission,and the experimental results which are consistent with theoretical analysis.Applying it to teaching can not only strengthen students’understanding of communication circuit knowledge,improve their practical and preliminary circuit design abilities,but also enable them to understand the practical role of circuit theory in engineering.
