Magnetic field analysis of air-core superconducting transformer

Abstract

In the applications of the superconducting wires to the a c power fleld, the magnetic fleld analysis is very important in order t o investigate their power loss and stability. In this paper, a calculation method of magnetic fleld in the air-core transformer, which is one type of the superconducting transformer, is introduced. Then, based on this method, the magnetic field acting on the transformer winding is analyzed. Results of analysis And that the magnetic fleld of the air-core superconducting transformer does not distribute uniformly and that the magnetic flefd under load has a rotating component.
