The creating of the ideal turnout switch for a highly branched Maglev system is still a challenging task, because the turnout is one of the most important and indispensable devices involved in the Maglev system. The unmovable electromagnetic turnout can easily move the Maglev vehicles running one way to another, by replacing the permanent magnets (PMs) with electromagnets. But there is still a difference between the normal permanent magnet guideway (PMG) and the area of the turnout switch, which cannot be used in real operation at high speeds. Thus, this paper introduces the possible way to improve the design optimization of the electromagnet used in the electromagnetic turnout of the high temperature superconducting (HTS) Maglev systems. In particular, the use of a compensation coil between magnetic poles was suggested and proved. An equivalent circuit of the electromagnet with compensation coil was built, the criteria for the identity of the magnetic circuit are used to compare with the proposed variant. The parameters of the magnetic field in the electromagnet were calculated and the graph of the magnetic induction was given. Consequently, further direction for improving the electromagnet was described which means this work provides valuable references for the future ideal design of the electromagnet as a crucial element of an electromagnetic turnout for Halbach PMG.

使用补偿线圈的电磁道岔设计优化


为高度分支的磁悬浮系统创建理想的道岔道岔仍然是一项具有挑战性的任务，因为道岔是磁悬浮系统中最重要且不可或缺的设备之一。通过用电磁铁代替永磁体（PM），不可移动的电磁道岔可以轻松地将磁悬浮车辆从一个方向移动到另一个方向。但普通永磁导轨（PMG）与道岔道岔面积仍有差距，无法用于高速实际运行。因此，本文介绍了改进高温超导（HTS）磁悬浮系统电磁铁设计优化的可能方法。特别是，建议并证明了在磁极之间使用补偿线圈。建立了带有补偿线圈的电磁体的等效电路，并使用磁路同一性的标准与所提出的变体进行比较。计算了电磁铁中的磁场参数并给出了磁感应强度图。因此，描述了进一步改进电磁铁的方向，这意味着这项工作为未来电磁铁的理想设计提供了有价值的参考，电磁铁是哈尔巴赫永磁发电机电磁道岔的关键元件。
