摘　　要：针对直接冷却超导磁储能(SMES)磁体在充放磁时交流损耗等原因导致磁体失超。提出对磁体动态热传输特性进行研究,利用有限元方法建立磁体有限元数学模型,对磁体在充放磁过程中温度变化进行模拟仿真;进行了直接冷却磁体的电流加载实验,仿真和实验结果表明:磁体及其低温系统具有良好的热稳定性。AC loss could lead to quench when Superconducting Magnetic Energy Storage （SMES） system charge and discharge to HTS magnet directly cooled by cryo-cooler. In order to research dynamic thermal characteristic of magnet, mathematics model of the magnet was established based on Finite element method （FEM）. Simulation of temperature variety was carried out when magnet was charged and discharged. The current load experiment was carried out on the directly conduction cooled magnet. The result of simulation and experiment shows the magnet and cryo-system be provided with favorable thermal stability.
