摘要
高温超导带材的弯曲通流特性决定了超导线圈的临界电流大小。文中针对典型的铋系和钇系高温超导带材,设计了一套测量其弯曲通流能力的装置,研究了77K、自场下高温超导带材在不同弯曲直径下的临界电流,以及双面弯曲再拉直情况下临界电流的恢复特性,并对实验结果进行了分析。
The critical current of superconducting coil is decided by the bending characters of HTS tapes. This paper de- signed a device aiming to measuring the Ic of YBCO and BSCCO tapes under different bending diamers at the temperature of 77K and self- field. The recovery characteristic of Ic after straightening was also discussed. Furthermore, some conclusions are drew based on the analysis of the experimental results.
