50kA超导变压器初级绕组设计制作及低温通电实验

The design and test of superconducting transformer primary coil

主要讨论了超导变压器初级绕组的设计、绕制以及低温通电实验,初级绕组主要采用2 942匝NbTi超导股线绕制,并经过真空压力浸渍而成。利用Ansys软件分析了其磁场分布。采用LHe浸泡式制冷,最大电流可达190A,中心场约为2T。

This paper focused on the design and manufacture of superconducting transformer primary coil. The primary coil was twisted by 2942 turns multi - filamentary NbTi wire. The coil was immersed in liquid helium. The maximum current was 190A and the centre field was about 2T. The software Ansys was used to analyze the distribution of the magnet field.
