Patent number: 9761366Abstract: A dry-type transformer for mobile applications includes a transformer core, at least one radially inner first winding segment, and at least one radially outer, second hollow cylindrical winding segment. The segments are wound around a common winding axis and the transformer core passes therethrough. The segments are nested inside one another and radially spaced apart from one another, such that a hollow cylindrical cooling duct is formed therebetween. Spacing is achieved by spacer elements arranged such that the cooling duct allows a passage of coolant in an axial direction. The spacer elements are formed and arranged along the radial circumference of the cooling duct over the axial length thereof such that the proportionate weight of the horizontal transformer can be borne on at least one contact surface of the at least second winding segment without causing deformation to the cooling duct.Type: GrantFiled: January 17, 2014Date of Patent: September 12, 2017Assignee: ABB Schweiz AGInventors: Benjamin Weber, Michael Luckey, Wolfgang Mönig, Marcos Bockholt

Patent number: 9368268Abstract: An underfloor transformer includes a layered transformer core and at least one electrical winding through which the transformer core extends along a limb axis. In each of two axial end regions of the transformer core, a securing device, which interacts with the transformer core mechanically, is provided. The securing devices are configured for such tensile force stressing. The underfloor transformer can be carried suspended therefrom.Type: GrantFiled: November 6, 2012Date of Patent: June 14, 2016Assignee: ABB TECHNOLOGY AGInventors: Michael Luckey, Marcos Bockholt, Benjamin Weber, Wolfgang Mönig

Patent number: 8786390Abstract: A transformer of dry design is disclosed having a core composed of amorphous material, which is sensitive to mechanical loads, having at least one winding former which surrounds the core and is in each case formed from at least one primary winding and secondary winding, and having at least one holding apparatus. A method for transformer production is also disclosed, wherein the holding apparatus is used to fix the at least one primary winding and secondary winding in each case and for this purpose it acts on each of the end faces of the at least one winding former.Type: GrantFiled: September 29, 2011Date of Patent: July 22, 2014Assignee: ABB Technology AGInventors: Michael Luckey, Wolfgang Mönig, Benjamin Weber, Karel Bilek, Martin Carlen, Jong-Yun Lim

Patent number: 8525628Abstract: The disclosure relates to a housing for an electric machine, for example, an electric power transformer, such as a dry-type transformer, with cooling channels being provided within the housing for a cooling medium. The electric machine and a cooling system can be arranged in the housing, with vertically arranged first and second channels for the cooling medium being provided. The medium can flow around the electric machine, with the housing accommodating the electric machine and the cooling system substantially forming a hermetic encapsulation.Type: GrantFiled: January 10, 2011Date of Patent: September 3, 2013Assignee: ABB Technology AGInventors: Benjamin Weber, Marcos Bockholt, Michael Luckey, Wolfgang Mönig, Jens Tepper

Publication number: 20120075047Abstract: A transformer core for a power transformer, and a power transformer including such a transformer core are provided. The transformer core includes at least two transformer core laminations which are arranged in parallel and are at least approximately congruently adjacent to each other. The transformer core laminations have a similar outline. At least one through-hole is arranged in the outline in each case. The transformer core laminations are comprised of at least predominantly an amorphous ferromagnetic material. At least one cooling channel is arranged between the transformer core laminations.Type: ApplicationFiled: November 15, 2011Publication date: March 29, 2012Applicant: ABB Technology AGInventors: Michael LUCKEY, Wolfgang Mönig, Benjamin Weber
