摘要
As a part of the Super-conductive AC Equipment (Super-ACE) project being performed from 2000 to 2004, an AC Magnet for a fault current limiter is being developed. This research focuses on fundamental technical items essential for a 66 kV class fault current limiter magnet wound with high-T-c superconductors operating at around 65 K. These items are high current capacity, high voltage insulation and sub-cooled nitrogen cooling. This paper describes experimental results obtained for a model coil wound with four-parallel Bi2223 tape conductors. Voltage-current characteristics, equal current distribution among tape conductors and overvoltage behavior are evaluated.
