| Popis: | In this study, we reduced the cable former (hereinafter, “copper wire”) diameter to verify the possibility of realizing the fault-current-limiting-type superconducting cable while maintaining the current-limiting ratio and the cable stability. Current application properties in the parallel connection of the copper stranded wire were analyzed with the superconducting wire with a different degree of non-resistance. Items that were verified included the change in the total current (the limited fault current), the voltage characteristics, and the results of the thermal stability evaluation through a resistance analysis. The verification targets included the combination of the superconducting wire without a stabilization layer and the copper wire (0.75 SQ and 1 SQ), the combination of the superconducting wire with a stainless stabilization layer and the copper wire (0.75 SQ and 1 SQ), and the combination of the superconducting wire with a copper stabilization layer and the copper wire (0.75 SQ and 1 SQ). Result showed that with the increasing degree of the superconducting wire non-resistance and the decreasing copper wire diameter, the limiting performance of the total current improved, but thermal stability was not stabilized. In addition, the superconducting wire volume was shown to have affected thermal stability. |
