摘要
以服务轨道交通为中心,符合城市环境和能源效率持续性的要求。将无线供电技术与电气化轨道交通技术相结合,取代传统的以接触网和接触轨为主的供电方式,可以降低日常的维护成本,提高铁路系统安全性,减少在恶劣天气中的晚点率,最终实现轨道交通系统更高效率运行。首先介绍感应式和谐振式两种适合轨道交通的电能传输方式;然后阐述目前国内外无线电能传输技术在轨道交通领域研究现状,重点提出感应耦合式和磁感应谐振式两种关键的无线供电技术在轨道交通领域应用需要处理的问题;最后对现有研究近况进行分析。
Focusing on service rail transit,which meets the requirements of urban environment and energy efficiency sustainability.The combination of wireless power transmission and electrified rail transit technology,replacing traditional contact and mesh-based power supply methods,can reduce the daily maintenance cost,improve the safety of railway system,reduce the late rate in bad weather,and finally realize the more efficient operation of rail transit system.Firstly,the two types of inductive and resonant energy transmission methods suitable for rail transit are introduced.Secondly,the current research status of radio energy transmission technology in rail transit field at home and abroad is described,focusing on the problems that need to be solved in the application of two key wireless power supply technologies of induction coupling and magnetic induction resonance in rail transit field.Finally,the current research status was analyzed.
