Smart superconducting cable winding body for power transmission fault current limit and production method thereof and power supply equipment used for a fault current limiter based on smart superconducting cable winding body
The present invention relates to a fault current-limited smart superconducting cable winding structure, wherein one portion of a superconducting cable is wound in a coil shape to have a solenoid structure so that the fault current-limited smart superconducting cable winding structure is installed in a limited space and capable of increasing inductive impedance and thus, can improve a current limiting function and can easily perform a fault current limiting function together with a transmission/distribution function even when installed at a bending point. In addition, according to the present invention, a manufacturing method of a fault current-limited smart superconducting cable winding structure is configured such that the smart superconducting cable winding structure which is used for dual purposes of a transmission/distribution cable and a reactor type fault current limiter can be conveniently and easily manufactured by a simple operation of inserting a metal core into a superconducting cable drum. Furthermore, according to the present invention, a superconducting cable winding structure-based power transmission device combined with a fault current limiter is capable of effectively performing cooling exclusively on the superconducting cable winding structure according to individual control of separated cooling units, and accordingly, it is possible to increase cooling efficiency and save energy consumption.
