Abstract

Recently, the high-temperature superconducting (HTS) devices and superconducting technologies have become widespread in the field of electric power. The 2G wires are expected to be used in future power applications because it has high properties in high temperature and high magnetic fields. One of the most promising applications for HTS coils in electrical engineering is for high-temperature superconducting fault current limiter. In this paper, the design, fabrication, and experiment of the combined YBCO/Bi2223 coils were described. Nine coils wound with 122 m YBCO tapes and three coils wound with 376 m Bi2223/Ag tapes, were assembled into the combined coils. The YBCO coils were in a noninductance configuration and the Bi2223/Ag coils were in a solenoid configuration. For getting higher resistances and rapid response to the fault current, the structure of the combined coils, the heat stability, and the insulation of the YBCO coils were the main targets in the development of the YBCO coils.
