摘要： This specification relates to fault current limiter (FCL). More particularly, to solve problems of protecting and designing current limiting impedance in a protective coordination system, as limitations of the related art, the fault current limiter may measure heat capacity of a current limiting impedance unit (200) by detecting fault current flowing to the current limiting impedance unit and limiting the fault current flowing to the current limiting impedance unit according to the measured heat capacity, which may result in preventing the current limiting impedance unit from being damaged due to the fault current, preventing an extended accident due to the damaged current limiting impedance unit and enabling a stabilized system and line protection.

摘要： A superconducting fault current limiter (10) is provided with superconducting elements (71, 72) that are in a superconducting state during electrification with a current value in a fixed range and in a normal conducting state during electrification with a fault current in which the current value exceeds the fixed range and is further provided with a coolant vessel (20), which accommodates a liquid coolant (60) and a plurality of superconducting elements, and a cooling means (40) that cools the liquid coolant within the coolant vessel. Within the liquid coolant, the superconducting element (71) for which the critical current is smallest among the plurality of superconducting elements is disposed on the upper side of any other superconducting elements (72). Thus, the superconducting element (71) is cooled, and the life of the superconducting fault current limiter as a whole is extended.

摘要： A new type of superconducting fault current limiter is disclosed, which can advantageously be used with high voltage transmission networks. The circuit is electrically connected to two terminals (144, 146), which connect to the transmission network. The superconducting circuit (120) is located within an enclosure or tank (112), which is electrically isolated from ground. Therefore, the voltage difference between the enclosure and the superconducting circuit, and between the enclosure and the terminals are significantly less than exist in current deployments. In some embodiments, the enclosure is electrically connected to one of the terminals, while in other embodiments, the enclosure is electrically isolated from the terminals. The circuit can be combined with other like circuits to address a wide range of current transmission network configurations.
