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
