Abstract

High-Tc superconducting fault current limiter (SFCL) with DC reactor is the power equipment which plays the role of limiting fault currents by inductance of the DC reactor. Therefore manufacture of the DC reactor is very important part in developing this type of SFCL. The DC reactor makes use of high-Tc superconducting (HTS) magnet. Because high-Tc superconducting wires are rectangular tape and contain ceramic compounds, the winding method and the tension control of the HTS magnet are different from those of normal conductor magnets such as copper winding magnet. In this research, we designed and manufactured the winding machine for HTS magnets. We fabricated four HTS magnets wound with various tension. Characteristics of the fabricated magnets are observed through measurements of critical currents. This paper suggests the optimal winding method of HTS magnets.
