Title: The current limiting effects of a matrix-type SFCL according to the variations of designed parameters in the trigger and current-limiting parts
Abstract: The analysis of various type SFCLs is actively in progress all over the world. In order to increase the capacity of a superconducting fault current limiter (SFCL), serial and parallel connections between superconducting units are essential. A matrix-type SFCL is composed of a trigger and current-limiting parts to improve the fault current limiting effects and the quenching characteristics when the superconducting units are connected in series and parallel. In this paper, we investigated the quenching current and the fault current limiting characteristics in accordance with the variations of designed parameters. We analyzed the characteristics on 1 × 3 and 2 × 3 matrix structures. As the turn’s number of reactors in the trigger part was increased, the critical currents of superconducting units were reduced because of the increase of magnetic field in the current-limiting parts. Therefore, the difference of quenching time of the superconducting units was reduced. When the resistance in the current-limiting part was increased, the fault current limiting effects were improved. As a result, we found that the shunt resistance of the current-limiting part contributed to improve the quenching characteristics between the superconducting units.
