Study on the Quench Protection Method of HTS Cable Consisted of YBCO Coated Conductor Using Various Type SFCLs

Abstract

As research on YBCO coated conductors (CCs) progresses, research on CCs with different stabilization layers is being actively conducted. Stainless steel stabilized coated conductor (SUS CCs) can be said to have a wide range of application as an insulation element with the specific resistance characteristic of its stabilization layer. Accordingly, this paper has produced a resistive type-fault current limiting module proper for limiting high current by parallel linking SUS CCs with the YBCO thin film which has been used as a fault current limiter. By using the produced fault current limiting module, the researcher examined resistance occurring in Cu CCs through linking resistive type-, flux-lock type- and flux-coupling type-fault current limiters with CCs for transporting high current with the Cu stabilization layer (Cu CCs). Analysis data on trends in resistance occurring in Cu CCs through linkage experiments of fault current limiters by type is expected to be used as reference material regarding the high-Tc superconducting cable to be produced with use of Cu CCs.
