摘要： A terminal apparatus for a superconducting cable system connects an overhead transmission cable or power appliance such as a breaker in an ambient temperature state to a superconducting cable through which power is transmitted at a cryogenic temperature. The terminal apparatus has: a refrigerant tub which is connected to the end of a superconducting cable and is filled with a refrigerant; a vacuum heat insulating container that surrounds the exterior of the refrigerant tub; a current lead having one end connected to the end portion of the superconducting cable and the other end connected to the overhead transmission cable or power appliance through the refrigerant tub and the vacuum heat insulating container; and a superconducting fault current limiter installed at a center portion of the current lead in the interior of the refrigerant tub to limit fault current. As the superconducting fault current limiter is built in the terminal apparatus, the terminal apparatus itself can play the role of a fault current limiter too. Hence, the terminal apparatus can protect a superconducting cable from a fault current directly by limiting the fault current flowed into the superconducting cable when a power transmission fault occurs.
