摘要
二代高温超导带材因其机械和磁场下的性能优于一代带材,近年来受到广泛关注。文中针对高温超导带材的特点,结合实验室的现有设备,设计了超导带材临界电流的测试平台,对三种二代高温超导带材在77K、不同磁场、不同角度下的临界电流进行了测量,分析了其在不同背景磁场和磁场角度下的各向异性,并用插值法拟合出了其临界电流与磁场及其角度的关系曲面,为超导磁体设计中高温超导带材临界电流的计算提供依据。
In recent years 2nd generation HTS tape attracts significant attention because its performance under tensile stress and magnetic field is superior to the 1 st generation HTS tape. Aiming at the HTS characteristics and combining with the existing laboratory equipment, this paper designed an Ic of HTS test bed. Three kinds of 2nd generation HTS tape were measured under different magnetic field and different angles in 77K, and Ic anisotropy was analyzed. Then Ic（B,O） urved surface was got by u- sing interpolation method, thus the basis for the calculation of Ic in the design of superconducting magnet was provided.
