Abstract: The short-circuit force of the helical winding will contain a large tangential force when the transformer shorted. The combined action of axial current component and radial leakage magnetic field will produce great torque. This paper established the coupling model of two dimensional and three dimensional magnetic field-structural force field of helical winding and calculated the leakage magnetic field of transformer and the tangential force of helical winding .The tangential force size and distribution law of the low voltage helical winding are obtained. It tested the reliability of the calculation method through the comparison and analysis of two kinds of modeling. On the basis of this, we studied the influence of helical Angle and axial compression force on the tangential displacement of helical winding .The results show the method is efficient for reducing winding tangential displacement in product design.

Keywords: Helical Winding, Tangential Force, Torqu, Helix Angle, Axial Compression Force, Tangential Displacement
