Abstract: The primary and secondary sides of the autotransformers have not only the coupling of magnetic field but also the connection of the circuit. Ultrahigh voltage autotransformers have a complex structure, which makes it have a very prominent problem of the electromagnetic properties in the operation of transformer. Therefore, in this study, based on the field-circuit coupled finite element method, 3D leakage magnetic field simulation of electromagnetic performance was performed under the short-circuited of a single phase three column autotransformer. The research analyzes the distribution of transformer leakage magnetic field distribution, and the loss distribution of clamp and pressing nail plate. The winding leakage magnetic field distribution of the single-phase three-column autotransformer is obtained, and the vortex distribution is optimized, moreover, the drawing board eddy current loss is reduced.
Key words: electrical appliances; autotransformer; leakage magnetic field; field-circuit coupling; finite element; eddy current loss
