Superconducting fault current limiter(sfcl) for fault current limiting and uninterruptible power supplying

PURPOSE: A superconducting fault current limiter for uninterruptible power supply and fault current limit is provided to improve the stability of a system by stably supplying power to an outage section generated by a fault current by using a third winding and a switch connected to a third winding. CONSTITUTION: A first winding(112), a second winding(114), and a third winding(116) are formed on the same iron core. A superconductor(120) is connected to the first winding or second winding. A first switch(132) is connected to the first winding or second winding. A first switch is opened to separate a fault section when a fault current is generated. A second switch(134) is short-circuited to stably supply power when the fault current is generated.
