Abstract: An exemplary transformer includes a transformer core having at least one core limb, a main winding arranged around a respective core limb in a hollow-cylinder-like winding region, and an auxiliary winding, which is electrically connected to the main winding and is arranged close to the core. The cross-section of at least one of the core limb and a core yoke formed of the transformer core has in a cross-sectional plane transverse to an extent of said core limb or said core yoke, at least two regions which are separated by an aperture, and at least one turn of the respective auxiliary winding is passed through the aperture.

Abstract: The disclosure is related to a dry transformer, which includes a transformer core with at least two parallel limbs and upper and lower yokes, and at least two hollow cylindrical coils, each arranged as neighbored coils around a limb of the at least two parallel limbs. A cooling system can include at least one wall-like diaphragm in-between the neighbored coils, which is in parallel to the orientation of the limbs.

Abstract: A transformer and a method of manufacturing a transformer are disclosed. The transformer can include a transformer core with at least three core limbs which are arranged in parallel with respect to one another and perpendicular to corner points of an area spanned by a polygon, and wherein axial end regions of each of the at least three core limbs transition into a respective yoke segment arranged transversely with respect to the axial end regions. Main windings can be arranged around each of the at least three core limbs in a hollow-cylindrical winding region. A magnetic cross section of a respective core limb can be greater than a magnetic cross section of the respective yoke segment. Additional windings can be electrically connected to a respective main winding and can be arranged around each of the respective yoke segments.
