Abstract: 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.

Abstract: 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.

Abstract translation: 用于移动应用的干式变压器包括变压器芯，至少一个径向内部第一绕组段和至少一个径向外部第二中空圆柱形绕组段。 这些段缠绕在共同的绕组轴上，并且变压器芯通过其中。 这些片段彼此嵌套并且彼此径向间隔开，使得在它们之间形成中空圆柱形冷却管道。 间隔是通过间隔元件来实现的，间隔元件布置成使得冷却管允许冷却剂在轴向方向上通过。 隔离元件沿着其轴向长度沿着冷却管道的径向周边形成和布置，使得水平变压器的相称重量可以承载在至少第二绕组段的至少一个接触表面上，而不会导致变形 冷却管道
