Magnetic Field Analysis of a Complex Construction Transformer Using Direct Field-Circuit Coupling Method

Abstract:

This paper deals with the main magnetic field distribution for a three-phase five-column disintegration transformer with the iron core disassembled into several parts owing to limited transport condition. The finite element method is employed to solve such a special configuration transformer, in which the direct field-circuit coupling formulation is derived and programmed by APDL programming language. The calculation results, such as the magnetic field distribution in transformer core, the exciting current magnitude and no-load loss are investigated. The optimum size of air gap between each separated iron core limbs is discussed.
