| 摘 要： | 高温超导磁体临界电流磁矢量分析法准确地预测了BSCCO高温超导磁体的临界电流,为了进一步验证该方法预测YBCO高温超导磁体临界电流的准确性,文中作者用9.3m二代高温超导YBCO带材绕制了一个内径为70mm,外径为100mm,共35匝的单饼,测试了单饼5-15匝,15-25匝,25-35匝和5-35匝在77K下的临界电流,并用磁矢量分析法进行了仿真分析。通过对比发现,仿真分析和实验结果的误差在5%左右,最大误差是6.75%,最小误差是4.77%,验证了磁矢量分析法在预测YBCO高温超导磁体临界电流时的准确性。

| Abstract: | The critical current of a HTS coil made of BSCCO HTS tapes could be estimated accurately by magnetic field vector analysis method.In order to verify the reliability of this method on HTS coil made of YBCO tapes,the author fabricated a HTS coil with 9.3m long YBCO coated tapes.The inner diameter of the coil was 70mm,the outer diameter was 100mm,and it had 35 turns in total.The critical currents of 5-15 turns,15-25 turns,25-35 turns and 5-35turns were tested by immerging it into liquid nitrogen.In addition,the critical currents were also calculated by magnetic field vector analysis method.By comparing the results of simulation and experiment,the relative errors between calculation results and test results were around 5% with the highest being 6.75% and the lowest 4.77%.The validity of this method on YBCO HTS coil was verified. |
