超导系统中线圈的绝缘材料/超导线之间的摩擦

Frictional between the Insulator/Conductor in Superconducting Magnets

】综述超导托克马卡装置的超导线圈绝缘材料／超导线系统因低温、绝缘材料收缩、脆裂和Ｌｏｒｅｎｔｚ力产生相对运行而引起磁体失超的原因及影响的因素。分析多对常用有机材料和金属材料摩擦系统，指出减少摩擦引起失超的方法，提出对大型超导磁体，如ＨＴ－７Ｕ超导托克马卡纵场系统。

In this paper, the normal of the superconductor in the superconducting tokamak fusion reactor caused by insulating shrink cracking, relatively motion between the insulator and conductor was viewed. Many pairs of the insulator/metal in cryogenics was discussed. The method to loss the frictional between the pairs was preferred. And giving the design of insulating system for large superconducting Tokamak, such as HT-7U which is fabricating.
