تكبير أثر القوى الكهرطيسية في المحولات الكهربائية

Abstract EN

High current in transformer windings induces excessive electromagnetic forces.

These forces are important in the design and operation.

This paper is focused on the distributing of electromagnetic forces on windings of transformer at high current condition.

Three dimensional finite element method –ANSYS – Software is used to calculate the magnetic flux and forces.

The impact of winding arrangement on the axial and radial forces are analyzed.

The results of research proved that these forces are very depended on transient state and position regarding of the electric current direction
