안정화 층을 갖는 YBCO Coated Conductor와 BSCCO 선재의 결합이 과전류 통전 특성에 미치는 영향

Effect of Transport Current Properties on Connecting of YBCO Coated Conductor having Stabilizer Layer and BSCCO Tape

YBCO coated conductor called the second-generation superconducting tapes have resistance increase significantly more than BSCCO tapes in terms of the speed or amount when quench occurs, they may have different ranges of application. Such characteristics are thought to get different properties by selection of stabilizing materials in manufacturing superconducting tapes. It is important in selecting superconducting tapes which will be applied to power devices in the future. In this study, one kind of BSCCO tapes and two kinds of YBCO CC with different stabilizing materials and one kind of YBCO CC with non stabilizing materials were used to compare and examine transport characteristics in flux-flow state and quench state with each tape joint of HTS tapes.
