Abstract:
Disclosed is provided a hybrid-type superconducting fault current limiter for rapidly limiting a fault current, the fault current limiter having a first circuit and a second circuit which are connected in parallel with each other, wherein the first circuit includes a superconductor and a circuit breaker which are connected in series with each other, and wherein the second circuit includes a driver having a driving coil and an electromagnetic repeller, a short contact connected in parallel with the driver, and a current limiting unit connected in series with a third circuit including the driver and the short contact. The hybrid-type superconducting fault current limiter comprises a power semiconductor element switch connected in series with the first circuit, the power semiconductor element switch normally maintaining an ON state and being activated and changed into an OFF state by a fault sensing signal generated according to an inflow of the fault current.
