The characterization of a Superconductive Current Limiting Fuse
초전도 한류퓨즈의 특성연구
Abstract
We investigated the basic properties of a superconductive current limiting fuse (SCLF) based on YBCO/Au films. The SCLF consists of meander type YBCO stripes covered with an Au layer for current shunt. The fault current was first limited to a designed value in less than 0.4 msec by resistance development in YBCO/Au upon quenching. This enables the SCLF to transfer small fault power and the suppressed current was sustained for more than 0.5 msec while Au layer melting and arcing. The arcing time was less than 2.5 msec, that is short enough to do self-interruption.
