- Abstract
- We report the increase of the current limiting capacity of SFCLs by using the basic 1×3 matrix module with 3 superconducting elements. To do this, we fabricated the basic superconducting module with the 1×3 matrix structure which consists of a trigger part and current limiting parts. Firstly, we analysed the current limiting characteristics of the basic superconducting module with the 1×3 matrix structure. Secondly, we investigated characteristics about the increase of the current limiting capacity of 2 × 3 matrix-type SFCLs and 3×3 matrix-type SFCLs which were connected in parallel with 2 or 3 basic 1×3 modules. From this procedure, we approved that the easy increase of the current limiting capacity of SFCLs could be realized throughout the simply parallel connection of basic 1 × 3 modules without complex wiring. We used YBCO superconducting thin films and constructed matrix-type SFCLs by using 9 superconductors and 3 reactors. Experimental results were reported in terms of the increase characteristics of the limiting capacity for fault currents and fault voltages.
