本文探讨了用Bi-2223高温超导导线作为故障限流器的可行性。与现有的块状或薄膜超导FCL相比，采用高温超导线的FCL在稳定性、结构灵活性和成本上具有一定的优势。即使使用高温超导线的FCL在正常状态下电阻为零，也需要作为双线绕组进行无感缠绕。本文提出了四种双线绕组的FCL模块，制作并在77 K条件下进行了短路试验。FCL模块分别具有不同的故障限流特性和稳定性。这些类型的模块有电磁阀、煎饼、浸渍环氧树脂的电磁阀和浸渍环氧树脂的煎饼。FCL模块在0.5 V至22 V的故障持续时间（0.1 s）内施加可控交流偏置。该测试中的故障发生过程与实际系统中的故障发生过程非常相似。在试验结果中，薄饼型比螺线管型更有效地限制故障电流。此外，与未浸渍的模块相比，浸渍环氧树脂的模块具有更有效的限流特性。螺线管式具有较好的稳定性。本文验证了高温超导线材整箱的可行性
This paper deals with feasibility of fault current limiter (FCL) by using Bi-2223 high temperature superconducting (HTS) wire. The FCL using HTS wire has some advantages of stability, flexibility of structure and cost compared with existing superconducting FCLs using bulk or thin film. Even if the FCL using HTS wire has zero resistance in normal state, it needs to be wound as a bifilar winding for non inductance. In this paper, four types of FCL module with bifilar winding were suggested, manufactured and experimented with short circuit tests in 77 K. The FCL modules have different fault current limiting characteristic and stability respectively. These types of module are solenoid, pancake, solenoid impregnated with epoxy resin and pancake impregnated with epoxy resin. The FCL module was applied by controllable AC bias during fault duration, 0.1 s, from 0.5 V to 22 V. A process of fault occurrence in this test is very similar to a fault occurrence in real system. In results of tests, the pancake type was more effective to limit a fault current than the solenoid type. Also modules impregnated with epoxy resin showed more efficient current limiting characteristics than nonimpregnated modules. The solenoid type has better characteristic of stability. The feasibility of the FCL by using HTS wire was verified by this paper
