摘　　要：由于超导托卡马克装置等聚变实验设备运行过程会产生较强的脉冲热负荷,这将对其配备的氦低温制冷系统的稳定运行提出更加苛刻的要求。本文介绍了大型氦低温制冷系统的一般流程,对比了三种超导托卡马克装置中产生的脉冲热负荷特征,并系统分析了超导托卡马克装置中低温制冷系统应对不同脉冲热负荷时的调控方法,为此类低温制冷系统的调控提供工程经验。The stable operation of the helium cryogenic refrigeration system equipped with the superconducting toka-mak device will be more demanding due to the strong pulse heat load generated during the operation of such fusion experi-mental equipment.In this paper,a general process of large-scale helium cryogenic system is introduced.The characteristics of pulsed heat load generated in three different superconducting Tokamak devices are compared.The commissioning meth-ods of the cryogenic system in superconducting Tokamak devices scoping with pulsed heat load are systematically ana-lyzed,which can be applied to other similar cryogenic system.
