    摘要:

    磁悬浮非接触式供电是一种将磁悬浮与无线传能相结合的技术。利用地面线圈与车载次级线圈之间的电磁耦合,实现电能传输。无论是应用于超导电动悬浮的线性发电线圈供电系统还是应用于电磁悬浮的感应式功率传输系统,都实现了列车运行时的非接触式供电,避免了接触式供电磨损、噪音以及气候敏感性、运行速度受限等问题。非接触式供电适用于不同类型的磁悬浮系统,有利于磁悬浮技术进一步商业化的发展。本文将重点介绍磁悬浮非接触式供电的国内外发展状况及其进一步应用面临的挑战。

    Abstract:

    Maglev non-contact power supply is a combination of maglev and wireless power transmission technology. The electromagnetic coupling, between the ground coil and onboard secondary coil, is used to realize power transmission. Both the linear generator coil power supply system applied in superconducting electrodynamic suspension and the inductive power transmission system applied in electromagnetic suspension have realized the non-contact power supply during the operation of the train, which also avoided the problems of contact power supply such as wear, noise and climate sensitivity. Non-contact power supply is suitable for different types of maglev system, in favor of the further commercial development of maglev technology. This paper will focus on the development of maglev non-contact power supply for domestic and overseas studies, and discuss the principle of non-contact power supply and the challenges faced.
