高温超导混合多点悬浮系统研究

传统的常导电磁悬浮系统气隙小、悬浮功率大，电动斥力不能实现静止悬浮，而且磁场污染大。经过比较分析，在单点悬浮实验的基础上，发展为四点高温超导与常导的混合悬浮系统，这种系统可以降低悬浮功耗、增大悬浮气隙，随着高温超导线材以及致冷技术的发展，高温超导与常导混合的EMS系统及纯高温超导EMS悬浮系统将在磁浮列车上得到广泛应用...

Research of HTS Hybrid Multi-point Magnetic Suspension System

The traditional normal conductive electromagnetic suspension system is of little air gap and large suspended power, the static suspension can not be realized by means of the electro-dynamic repulsion force and also it has more serious magnetic field pollution. Through the comparative analysis, this paper presents a new hybrid suspension system with the four points of high tempera- ture superconductive magnets and a normal conductive coil on the basis of the single-point suspension experiment. The suspension system can greatly reduce the suspended power dissipation and achieve the greater suspended air gap. With the quick development of HTS wire and refrigeration techniques, the hybrid EMS system with HTS and normal conductive coils and the pure HTS EMS system will be widely applied on maglev trains.
