Patent number: 11062835Abstract: A vehicle transformer has a transformer core with two opposed yokes and at least two limbs extending in between them along a parallel limb axis, wherein a support structure is provided at each of the yokes for carrying the vehicle transformer with horizontal oriented limb axis, wherein a hollow cylindrical coil with at least one respective electrical winding is arranged around at least one of the limbs. The coil may be rigidly connected with the limb so that the flexural resistance of the rigid combination of both is improved therewith compared to a combination of both without rigid connection.Type: GrantFiled: April 7, 2017Date of Patent: July 13, 2021Assignee: ABB Power Grids Switzerland AGInventors: Benjamin Weber, Karl-Heinz Zillmann, Wolfgang Moenig

Patent number: 8692643Abstract: An exemplary transformer winding including at least two hollow-cylindrical, axially adjacent winding modules, which are arranged about a common winding axis and have an electrical conductor wound in layers, and a common electrical insulting layer, through which the winding modules are enveloped. The insulating layer has at least one annular, radial depression or annular, radial elevation, which is salient transversely to the winding axis on the radial outer face of said insulating layer.Type: GrantFiled: July 3, 2013Date of Patent: April 8, 2014Assignee: ABB Technology AGInventors: Benjamin Weber, Bhavesh Patel, Burak Esenlik, Frank Cornelius, Marcos Bockholt, Jens Tepper, Karl-Heinz Zillmann

Patent number: 8344840Abstract: A transformer is provided with at least one core leg on which three windings are arranged side by side, whose discharges are designed to be mutually insulated. Each winding is formed by a near-core low-voltage winding, which are each wound by an associated high-voltage winding, and the discharges of the low-voltage windings are axially designed, so that the lateral spacing of the windings to each other is minimized.Type: GrantFiled: April 27, 2011Date of Patent: January 1, 2013Assignee: ABB Technology AGInventors: Karl-Heinz Zillmann, Wolfgang Mö nig, Benjamin Weber

Patent number: 8314675Abstract: A method is disclosed for production of a winding block for a coil of a transformer, having at least one winding composed of electrically conductive wire or strip material with a plurality of turns. An insulating layer is composed of electrically insulating fiber material with a specific number of windings of the insulating fiber material. The turns composed of electrical conductive material are fitted independently of the turns of the insulating material and, after a predetermined number of turns of electrically conductive material have been fitted, a smaller number of turns of electrically insulating material are fitted over the same section onto these turns of electrically conductive material, such that electrically insulating material which remains before reaching a number of turns of electrically conductive material is used as edge insulation.Type: GrantFiled: August 5, 2010Date of Patent: November 20, 2012Assignee: ABB Technology AGInventors: Karl-Heinz Zillmann, Rudolf Schutzeichel, Christian Gruettner, Benjamin Weber

Patent number: 8274354Abstract: The disclosure relates to a transformer having a yoke which has a crosspiece and at least two limbs, over which limbs a coil is placed in each case, and having at least one carrier on which the crosspiece is fixed and which has bearing faces for the coils. At least two supporting blocks for each coil are mounted on each bearing surface. The supporting blocks are fitted with elastic compensation elements on the coil-side carrying face and have, on their longitudinal side faces, which run perpendicular to a carrying surface, at least one strip which extends the creepage path and runs in the longitudinal direction and parallel to the carrying surface of the supporting block.Type: GrantFiled: August 20, 2010Date of Patent: September 25, 2012Assignee: ABB Technology AGInventors: Karl-Heinz Zillmann, Wolfgang Moenig, Benjamin Weber
