  • Patent number: 7675719
    Abstract: The present invention provides a current limiting module and a hybrid current limiter using different kinds of superconducting wires. The current limiting module includes a first superconducting wire that is wound in a predetermined direction, and a second superconducting wire that has quench characteristic different from the first superconducting wire and is wound to generate magnetic flux in a direction opposite to magnetic flux induced by the first superconducting wire. According to the present invention, inductance is generated due to unequal supply of fault current. Therefore, it is possible to prevent current from being suddenly increased, and to reduce the number of superconducting wires required to manufacture the current limiting module. Further, the hybrid current limiter does not need to include a separate coil for operating a fast switch.
