在真空管道高温超导磁浮实验系统中,采用圆环形单边长初级直线感应电机驱动磁浮列车做高速环形运动,为了提高驱动系统的效率和功率因素,降低系统能耗及电源容量,直线电机采用分段供电技术。本文针对真空管道高温超导磁浮实验系统的高速运行,分析研究了直线电机分段供电原理及列车的安全运行状况,设计完成了用于真空管道高温超导磁浮实验系统的环形分段供电加速器,并对加速器的响应速度和安全监控功能进行了测试,结果表明该加速器具有较高的响应速度,控制系统能对小车的运行状态做出准确的判断和保护,为真空管道高温超导磁浮交通系统的应用提供设计参考。
英文摘要：
The ring-shaped segment-powered accelerator,dedicated to the annular single-side long primary linear induction motor which drives the high-temperature superconducting（ HTS） maglev train at high speed in circular evacuated tube,was designed and fabricated,on the basis of the segment-powered technology and safety requirements. Application of the segment-powered technology to SLLIM＇s power-supply results in a significant increase of the efficiency,an improvement of the power factor and a reduction of both the power consumption and power capacity. The response speed and operation safety of the newly-developed accelerator were simulated in the experimental HTS maglev system. The simulated results show that the prototyped accelerator has a high respond speed and its control-unit is capable of accurately acquiring the motion data and providing effective protection of the maglev train.We suggest that the novel accelerator be of much technological interest in HTS maglev transportation in evacuated tube.
