Definitions
- the invention relates to a dry-type transformer for mobile applications, comprising a transformer core and at least one radially inner first and one radially outer second wound around a common winding axis and penetrated by the transformer core hollow cylindrical winding segment, which are nested and radially spaced from each other, so that between a hollow cylindrical Cooling channel is pronounced, wherein spacer elements are provided for spacing, which are arranged such that the cooling channel can be flowed through in the axial direction of a coolant.
- Energy supply systems for mobile consumers are typically constructed in a single phase, ie the supply takes place via a single supply line, wherein the return line then takes place via the metallic rail.
- the return line then takes place via the metallic rail.
- two supply lines are usually provided due to the non-existent and usable as a return rail rail.
- the network frequency in such applications at least in Europe 16 2/3 Hertz, in some cases, such as S-Bru also isolated DC voltage is used.
- a dry-type transformer as defined in claim 1.
- an alternative cooling system is provided, which works without oil but preferably with air. Due to the lower heat capacity of air, a significantly enlarged contact surface of the transformer winding to the cooling medium is therefore provided according to the invention. Furthermore, an increased coolant throughput, for example by means of a blower, is advantageous.
- the transformer lying, so that the winding axis of the windings thus extends in a horizontal plane.
- a particularly flat and more planar construction of the transformer is achieved, which accommodates the available flat but rather large space in the underfloor area.
- the at least one first and the at least one second winding segment are galvanically connected in series, so that an autotransformer is formed.
- This optionally has several taps and is characterized by a particularly high power density.
