摘要

The fault current limiting type smart superconducting cable winding structure of the present invention increases the size of the inductive impedance while being installed in a limited space by winding a part of the superconducting cable in a coil shape to have a solenoid structure, thereby improving the current limiting function. In addition, even if it is installed at a bending point, it has a technical feature that a fault current limiting function as well as a transmission and distribution function is performed smoothly. In addition, the manufacturing method of the fault current limiting type smart superconducting cable winding structure of the present invention is simple by simply inserting the metal core into the superconducting cable drum itself to the smart superconducting cable winding structure used for dual purposes of transmission and distribution cables and reactor type current limiters. And make it easy to manufacture. In addition, the power transmission device for the current limiter based on the superconducting cable winding structure of the present invention can perform effective cooling limited to the superconducting cable winding structure according to individual control of the separated cooling unit, thereby increasing cooling efficiency and reducing energy consumption. It has technical features that can achieve savings.
