A Winding, A Transformer And A Transformer Arrangement

Abstract: The disclosure relates to a winding (110) for a phase winding of a transformer (20). The winding (110) comprises a plurality of winding portions (116) arranged along a coil axis (z). The plurality of winding portions (116) comprise a first winding portion (116a) arranged at a first end (110a) of the winding (110) and a second winding portion (116b) arranged at a second end (110b) of the winding (110). The winding (110) further comprises at least a third winding portion (116c) arranged along the coil axis (z) between the first winding portion (116a) and the second winding portion (116b). The first winding portion (116a) and the second winding portion (116b) have a first winding portion stiffness as seen along the coil axis (z) and the at least third winding portion (116c) has a second winding portion stiffness as seen along said coil axis (z). The second winding portion stiffness is greater than the first winding portion stiffness. The third portion (116c) has a third portion center point (C3) on the coil axis (z), equidistantly spaced at a distance (d) from the first winding portion (116a) and from the second winding portion (116b), which third portion center point (C3) is located closer to the first end (110a) of the winding (110) than the winding center point (C). The disclosure also relates to a transformer (20) comprising the winding (110) and to a transformer arrangement comprising the transformer (20).
