The method solving short-circuit impedance between two interleave windings in the multi-winding core-type transformer with finite element method
In this paper, the layout of the locomotive main transformer windings is given at the beginning. Then the six layout modes of its double-winding transformer are set forward. It is impossible to calculate accurately all kinds of short-circuit impedance of the double-winding transformer with the usual method. This paper solves the impedance with the finite element method (FEM). This paper describes the electromagnetic field theoretical bases, introduces two sets of FEM to solve the impedance, and finally gives the magnetic flux line of the transformer's symmetric section and calculation results. Experimental results show that the solved results with FEM is correct.
