Resistive-type superconducting fault current limiters (R-SFCL) can limit the short-circuit fault current (SCFC). But superconducting tapes can not quickly recover to the superconducting state after deep quench. In response to minimizing the problem, this paper proposes a new resistive-inductive superconducting fault current limiter (RI-SFCL) and the current limiting transfer characteristics and investigates the recovery characteristics of it. The results show that RI-SFCL improves the fault current limit rate and significantly delays the emergence of sub-peaks of limiting current, reducing the rise rate of limiting current. Moreover, the recovery time of RI-SFCL can be less than 300 ms at 13 times the Critical expected SCFC. From the experimental results, the HTS tapes can be recovered within 300 ms when the heat generated during the current limiting process is not more than 215 J/m. Finally, the relation between the inductance and recovery time is given to provide a basis for the RI-SFCL design. |
