Abstract:
1. A method of manufacturing a continuous disk winding for high-voltage superconducting transformers, comprising the steps of: lapping a high-temperature superconducting wire using Kapton films to apply multiple layers of insulation around the high-temperature superconducting wire; fixing one end of the high-temperature superconducting wire to a current inlet terminal of a bobbin, and winding the high-temperature superconducting wire on the bobbin by a predetermined number of turns to form a layer of windings; fitting an annular disk having a slit formed therein onto the bobbin, the slit being formed along the circumference of the disk and to be inclined from the inner side of the annular disk towards the outer side thereof; inserting the high-temperature superconducting wire into the slit of the disk to pass through the annular disk smoothly along the inclined slit and winding the high-temperature superconducting wire by the predetermined number of turns to form a next layer of windings; repeating the above steps of fitting an annular disk, and inserting and winding the high-temperature superconducting wire to form multiple layers of windings; and fixing the other end of the high-temperature superconducting wire to another current inlet terminal of the bobbin.
