Abstract: The present disclosure provides a noise/vibration reduction device for transformers. An inner space 12 may be formed inside a tank 10 constituting the exterior of a transformer. The noise/vibration reduction device 20 may be installed on inner surfaces of tank side walls 14 constituting the outer surfaces of the tank 10. The reduction device 20 may include a plurality of support members 26, 28, 30 installed between a plurality of through hole plates 32, 34, 36, whereby a first space 38, a second space 40, and a third space 42 may be formed between the through hole plates 32, 34, 36 and the tank side walls 14. A first through hole 32?, a second through hole 34?, and a third through hole 36? may be formed in the through hole plates 32, 34, 36, respectively. By varying a diameter (D) and a length (T) of the through holes 32?, 34?, 36? and a distance (L) between the through holes 32?, 34?, 36?, noise having different frequencies may be removed from each of the through hole plates 32, 34, 36.

Abstract: The present invention discloses a superconducting wire transposition method and superconducting transformer whose winding is formed of superconducting wire to enable the formation of transpositions. The superconducting wire transposition method characterized of different winding start positions of at least two disks wound with a plurality of parallel superconductive wires, and usage of different superconducting wires for conductors to be connected between the disks, thereby forming transpositions outside of the disks. Preferably, part of the plurality of disks are rotatably assembled in pairs so as to form transpositions while maintaining a total number of windings equally. Therefore, according to the present invention, transpositions can be formed without bending or welding superconducting wires and thus, deteriorations in superconductivity can be prevented.
