本文研究了一种连续型故障限流（FCL）元件，这种元件在整个衬底上淀积有超导薄膜，在超导薄膜上淀积一层曲折形的金层。通过MOD法制备的YBCO超导薄膜的实验和有限元分析，比较了S-N转变前FCL元件局部区域的电压产生。考虑超导体中临界电流密度（JC）分布的有限元分析，研究了JC分布的不均匀性对这种FCL元件限流特性的影响。描述了非均匀J-C分布FCL元件中的电磁现象。
The authors have studied resistive-type fault current limiting (FCL) elements which have superconducting thin film deposited on almost whole area of the substrate and a gold layer deposited in the shape of meander on the superconductor. From experiments using YBCO thin film superconductor fabricated by MOD (metal organic deposition) method and FEM analysis, voltage generation at local areas of the FCL element before the S-N transition is compared. FEM analysis with critical current density (J C) distribution in the superconductor taken into account is also carried out to study the influence of inhomogeneous J C distribution on the current limiting characteristics of this type of FCL element. Electromagnetic phenomena in the FCL element with inhomogeneous J C distribution are clearly described.
