Title:
超伝導抵抗型限流器
Document Type and Number:
Japanese Patent JP4295189
Kind Code:
B2
Abstract:
Disclosed is a resistive superconducting fault current limiter capable of enhancing a current of a superconducting device thereof, capable of preventing heat generated at a linear coil, capable of removing a magnetic field generated through the linear coil when a normal current is applied to a circuit of a power system, and capable of using not only a BISCCO based superconducting device but also a YBCO based superconducting device with using a magnet generating device separated from the circuit of the power system so that a current of the power system can not flow to the linear coil of the resistive superconducting fault current limiter when a normal current flows to the power system. The resistive superconducting fault current limiter comprises: a superconducting fault current limiting module composed of at least one superconducting fault current limiting device; a magnetic field applying unit installed to surround a periphery of the superconducting fault current limiting module as a circular shape, for applying a magnetic field to the superconducting fault current limiting device; and a current transformer for inducing a current converted from the current flowing on the circuit of the power system by a non-contact and thereby supplying the induced current to the magnetic field applying unit.
