  • Fault current limiter
    Patent number: 10651646
    Abstract: 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.
