| 摘 要： | 文中对超导带材的失超产生机理进行了详细分析,建立了其失超传播的计算模型。在此基础上,对Bi-2223/Ag高温超导带材失超传播进行了实验研究,用四引线法测得不同条件下其失超传播的U-t曲线,由此计算出Bi-2223/Ag超导带材的失超传播速度为0.4cm/s～1.98cm/s。实验结果表明:带材的失超传播速度与载流大小有关,与触发失超的能量无关,带材载流越大,失超传播得越快。 |

| Abstract: | This paper analyzed the quench mechanism of superconducting tapes,then the calculation model of its quench propagation was established.On this basis,the quench propagation of Bi-2223/Ag HTS tapes has been studied;under the condition of different ways,the U-t curve of tapes has been achieved through the measurement of four leads.After calculating,the quench propagation velocity of Bi-2223/Ag superconducting tapes was 0.4cm/s to 1.98cm/s.Experiment results showed that the quench propagation velocity of tapes was relevant to carrying current but was independent of trigger energy;the more carrying current was,the quickly quench propagated. |
