Document Type and Number:
WIPO Patent Application WO/2023/101187
Kind Code:
A1
Abstract:
A superconducting current-limiting type DC circuit breaker according to an embodiment of the present invention, comprises: a current-limiting unit connected to a power system; and a circuit breaking unit connected to an end of the current-limiting unit, wherein the current-limiting unit includes a superconductor element, and when a fault current is applied to the power system, the superconductor element becomes a normal conducting state to generate a superconducting element resistance in the current-limiting unit.
