Provided is a fault current limiter that uses a superconductor and can rapidly restore a superconducting state after a current limiting operation. The fault current limiter is configured to perform a current limiting operation through the use of a superconductor and includes a superconducting member (a member including a holding container, a filler and a superconducting wire) including the superconductor, a cooling container, and a suppression member (fins). The cooling container is configured to hold therein the superconducting member and house therein a coolant for cooling the superconducting member. The suppression member (fins) is configured to prevent a boiling state of the coolant from transiting from a nucleate boiling state to a film boiling state in the case where the coolant boils on a surface of the superconducting member (a surface of the holding container) due to a temperature rise of the superconductor during the current limiting operation. |
