作为2000年至2004年执行的超导交流设备（Super-ACE）项目的一部分，正在开发用于故障限流器的交流磁体。本研究的重点是基本的技术项目所必需的66千伏级故障限流器的磁铁缠绕高T/sub c/超导体在65 K左右工作。这些项目是高电流容量，高电压绝缘和过冷氮气冷却。本文介绍了四个平行的Bi 2223带导体缠绕的模型线圈的实验结果。电压-电流特性，等电流分布之间的磁带导体和过电压行为进行了评估。
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/sub 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.
