Abstract

BACKGROUND

Studies of the normal zone in high-temperature superconducting wires are extremely important for power applications, such as fault current limiters, motors, cables etc. We studied the temperature distribution and normal domain propagation in high-temperature superconducting YBCO tape with highly resistive substrate.

FINDINGS

For applied voltages exceeding a certain threshold value the normal domain was found to become unstable and started to propagate along the tape.

CONCLUSIONS

The normal domain in superconducting tape with highly resistive substrate appears when voltage is applied to the sample. At voltages greater than the threshold value, the domain starts to move. This motion enables us to find the domain temperature and potential profile.

摘要

背景

高温超导线材正常区的研究对于诸如故障电流限制器、电机、电缆等电力应用极为重要。我们研究了具有高电阻衬底的高温超导YBCO带材中的温度分布和正常区域传播。

研究结果

发现当施加电压超过某一阈值时，正常区域变得不稳定并开始沿带材传播。

结论

当对具有高电阻衬底的超导带材施加电压时，正常区域出现。在电压大于阈值时，该区域开始移动。这种移动使我们能够确定该区域的温度和电位分布。
