The present invention relates to a superconducting wire winding device, and in particular, two winding supply parts are formed so that the superconducting wire can be uniformly wound without any impact or influence on the winding part to minimize the damage of the superconducting wire during winding. The present invention relates to a superconducting wire winding device and a winding method having excellent electromagnetic characteristics, and a double pancake coil manufactured by the same.

Since the discovery of the superconductivity phenomenon, efforts to apply the superconductivity technology to the electric power field continue to this day in developed countries and around the world, and the discovery of high temperature superconductivity (HTS) is based on liquid nitrogen in the conventional cryogenic cooling method using liquid helium. By adopting a cooling method using a freezer, it is possible to significantly reduce the volume and maintenance cost of the freezer section. The material of the high temperature superconductor conductor used in the superconducting power equipment is made of brittle metal oxide ceramic, which is made of tape-type joists with metal coating material, and is wound in the shape of a double pancake coil. The double pancake coil has a variety of forms, such as circular or racetrack type, depending on the purpose of use.

The double pancake coil has superconducting wires wound in opposite directions to the first and second layers, and the double pancake coil is formed to have the same cylindrical shape or racetrack type in the first and second layer windings as needed. . Such a double pancake coil is directly wound on the double pancake bobbin, or after winding on a predetermined winding frame, there is a method of separating only the double pancake coil and stacking it on the bobbin. In this case, it is important to minimize damage to the superconducting wire.

As such, the superconducting wire is subjected to a lot of electrical and mechanical influences on the direction of tensile stress, bending stress, and stress. If the superconducting wire is not wound uniformly by the flow or movement of the bobbin during winding, the superconducting properties are deteriorated or unstable.
