滑动式电能传输技术是根据负载工作在移动场合而提出的一种新型电能传输方式,不仅突破了传统电能静止传输的不足,而且简化系统的运行和维护。首先基于传统变压器原理介绍了两种常见的滑动式变压器结构,并在此基础上分析滑动式变压器工作原理。通过建立有限元分析瞬态模型,分析其磁场分布情况和感应电动势。最后通过具体的实验装置,验证了技术的可行性,为今后的滑动式电能传输技术提供理论指导。

As a new power transmission means for loads working in sliding applications, the sliding power transmission technology does not only solve disadvantages of traditional stationary power transmission, but also simplifies system operation and maintenance. Firstly, this paper presents two types of common sliding transformer structures based on the conventional transformer principle. Then, it analyzes the operational principle of the sliding transformer, and by setting up an instantaneous FEA model, analyzes its magnetic field distribution and induced electromotive force. Finally, a specific experiment setup is used to verify the feasibility of the technology and provide theoretical guidance for future sliding power transmission technology.
