摘要： A fault current limiter, including: two inductors, a direct current circuit breaker, a shunt resistor, a first fixed resistor, and metal oxide arresters. The two inductors include wound superconducting wires. The inductors have identical number of windings and identical structure. Magnetic fluxes of the inductors are forward coupled, and the inductors are connected in parallel to form a superconducting inductor structure. The direct current circuit breaker and the superconducting inductor structure are connected in series to form a series branch. The shunt resistor is connected in parallel to the series branch. The first fixed resistor is connected in parallel to the direct current circuit breaker. The metal oxide arresters are two in number, and are connected to two ends of the inductors in parallel.

摘要： A superconducting arcing induction type DC circuit breaker includes a superconducting fault current limiter and an arcing induction type DC circuit breaker connected in series to each other. The arcing induction type DC circuit breaker includes an induction member that has a through-hole, is continuously formed in a 360-degree direction, and has a certain shape and thickness, and an induction needle that protrudes from an inner surface of the induction member toward a center of the induction member. A contact point where an anode and a cathode, which are mechanical contacts, approach from opposite directions and come into contact with each other is formed in the through-hole of the induction member, and the anode and the cathode are separated in a direction far away from each other. The induction needle induces arc generated upon contact opening when the anode and the cathode are separated from each other in the event of system accident of DC power or AC power, and the induction member quenches the induced arc by the flow of the induced arc to ground through a ground line.

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 cryogenically-cooled HTS cable is configured to be included within a utility power grid having a maximum fault current that would occur in the absence of the cryogenically-cooled HTS cable. The cryogenically-cooled HTS cable includes a continuous liquid cryogen coolant path for circulating a liquid cryogen. A continuously flexible arrangement of HTS wires has an impedance characteristic that attenuates the maximum fault current by at least 10%. The continuously flexible arrangement of HTS wires is configured to allow the cryogenically-cooled HTS cable to operate, during the occurrence of a maximum fault condition, with a maximum temperature rise within the HTS wires that is low enough to prevent the formation of gas bubbles within the liquid cryogen.

摘要： An object of the present invention is to provide a method for protecting a superconducting coil, which method prevents damage to the superconducting coil caused by a quench or the like, in a new way, without using a voltage (a change in voltage) generated in the superconducting coil. Provided is the method for protecting a superconducting coil made by winding tape-like superconducting wire having a superconducting layer. Power from a power supply is shut off based on the magnitude of a screening field, which is a difference between a measured magnetic field B in a direction of a thickness of the superconducting wire at a predetermined position, and a magnetic field Bcal in the direction of the thickness of the superconducting wire calculated disregarding an effect of screening current.
