摘　　要：介绍了直接冷却高温超导储能磁体的基本结构.分析了磁体的电磁特性,分析结果表明,磁体电磁设计中采用端部两对饼并联的方式,削弱了磁体端部磁场径向分量,提高临界电流,磁体表现了较好的电磁特性;仿真了磁体与电力系统进行功率交换时的热特性,仿真结果与实验结果两者温度变化总体趋势是一致的;介绍了磁体的冷却实验和磁体系统的动态模拟实验结果,实验结果表明磁体的冷却措施和低温系统的冷却方案是可行的,磁体具有较好的热稳定性.The basis components and the experiment of 35kJ conduction-cooled high Tc superconducting magnet in China is described. The electro-magnetic characteristics is analyzed. The magnet presented the good electro-magnetic characteristics as the critical current was improved by reducing the radial magnetic component with two double pancakes connecting in serial. The simulation is performed to investigate the thermal characteristics in the exchange with the power system. The variation of temperature in the magnet simulation is resemble to the experiment result.
