- Abstract
- The advantages of the YBCO thin film wire, which is creating expectations as a next-generation superconducting current-limiting element, are its high index value, current density, and convenience when its capacity is increased by increasing its length. In particular, the stabilization layer of the YBCO thin film wire, which determines its abnormal current protection and excitation characteristics, can diversify its applications to superconducting power devices, depending on the specific resistance of the material of its stabilization layer. Thus, an analysis of the excitation characteristics of the YBCO thin film wire according to the material of its stabilization layer and the existence of the stabilization layer is a very important study subject. Accordingly, this study was conducted to evaluate the capabilities of the YBCO thin film wire as a current-limiting element using a YBCO thin film wire with no stabilization layer. For this purpose, the voltage-current characteristics of the YBCO thin film wire immediately after the quenching, according to the size and time of the fault current applied from the voltage source, were analyzed. Additionally, the wire's resistance-increasing tendency and its tendency to return to its superconducting state immediately after the quenching were examined. The results of this study present the evaluation data for the verification of the phase transition characteristics of the YBCO thin film wire with no stabilization layer and its potential as a superconducting element for the superconducting current limiter.
