对超导体抑制故障电流的电力应用进行了研究。开发了一种使用 Bi-Sr-Ca-Cu-O 圆柱体的超导故障电流限制器。该限制器由用于产生交流磁场的初级绕组和用于屏蔽磁场的超导圆柱体组成。当故障发生时，超导圆筒失超，圆筒内部形成磁路。结果，限制器具有高阻抗，从而限制故障电流。分别在无铁芯、有铁芯、铁芯铜柱作为次级绕组三种情况下进行实验。在每种情况下，故障条件下限制器的阻抗分别是正常条件下的1.4倍、10倍和5.9倍。
The power application of a superconductor to restrain a fault current has been researched. A superconducting fault current limiter using a Bi-Sr-Ca-Cu-O cylinder has been developed. This limiter consists of the primary winding for generating an AC magnetic field and superconducting cylinder for shielding the field. When fault occurs, the superconducting cylinder quenches and a magnetic circuit is formed inside the cylinder. In the result of that, the limiter has a high impedance thus the fault current is limited. Experiments were carried out in three conditions which are without an iron core, with an iron core, and with an iron core and a copper cylinder as a secondary winding. In each condition, the impedance of the limiter under fault conditions was 1.4 times, 10 times, and 5.9 times as high as the one under normal conditions.
