    • PURPOSE: A cooling system of a superconducting fault current limiter using solidification refrigerant is provided to reduce a recovery time for return to a normal state by quickly absorbing joule heat in an accident mode. CONSTITUTION: A solidification refrigerant container(30) is built in a current limiter container, and filled with solidification refrigerant as having a superconducting element(38).

The solidification refrigerant container comprises a cylindrical body(32) and a sealing cap(34). A copper network(40) improves a cooling speed of the element by being disposed within the solidification refrigerant container so as to surround the superconducting element.
