摘要： PROBLEM TO BE SOLVED: To make a transition (quenching) from a superconducting state to a normal conducting state uniform and easy in a superconducting current limiting device which is a current limiting element such as a leakage current limiter formed by winding a coil on a superconductor. SOLUTION: In a superconducting current limiting device comprising a superconductor component 1, each superconductor component comprises a superconductor body 2 on which a coil 3 is wound, and the coil 3 is electrically connected to the superconductor body 2. Then a magnetic field is generated on the superconductor by a current flowing through the coil on transition of the superconductor from the superconducting state to the normal conducting state. The magnetic field makes a transition (quenching) from the superconducting state to the normal conducting state smooth, and as the device is self triggering (induction), fault state detection and the generation of the magnetic field for quenching are not required.
