Definitions
- the invention relates to a transformer comprising two coils, each coil having a core and a plurality of windings and wherein the coils in a
- Transformers or their coils, are often positioned so that their longitudinal axes are oriented vertically. As a result, a relatively high height is achieved. Furthermore, transformers are usually not designed to withstand strong vibrations without damage. In certain applications, however, there is a need to arrange a transformer in a machine room, in particular a rail vehicle. In a machine room, often only a certain space is available for constructing a transformer. Furthermore, a transformer in a
- Engine room of a vehicle may be exposed to significant vibration.
- the invention is therefore based on the object to design a transformer such and continue to form that this shows a long operating life with a low and compact design in a vehicle.
- the above object is achieved by a transformer with the features of claim 1.
- the transformer mentioned above is characterized in that the support means has feet for setting up the support means on a base, wherein the longitudinal axes of the coils by placing the support means on the base are horizontally oriented.
- Vehicles especially rail vehicles, can be used. It has been recognized that, in particular, voltage gaps must be maintained in a tight space and the transformer must withstand high mechanical loads.
- a suitable support means coils can be arranged horizontally to a base. As a result, a certain height is not exceeded, even if the coils are relatively long. Furthermore, the coils are stored in the support device against vibrations.
- the feet have means for fixing the carrying device on the base.
- the means may be formed as passages for screws.
- the transformer can be connected to a vehicle so that it can not be displaced or displaced.
- the support device has two spaced-apart feet, wherein a press beam protrudes from each foot and wherein the coils extend between the press beams.
- the coils can be stacked one above the other in the support means, so that their longitudinal axes are oriented in parallel.
- the coils can be fixed to the press beams and stored against vibrations,
- a pressing beam is provided with at least one strut and / or reinforcement for stiffening.
- Press beam is avoided. Furthermore, a displacement of the coils is avoided.
- the connections to the base in order to control large forces in the direction of travel, transverse to the direction of travel and in the vertical direction, the connections to the base, in particular a car floor, must be designed in a special way.
- the feet are connected by a central strut. This also makes it possible to compensate for large forces in or transverse to the direction of travel of the vehicle without the press beams bending noticeably.
- a slipping of the coils is advantageously avoided.
- the center strut advantageously extends parallel to the longitudinal axes of the coils. As a result, a compression of the support device in the direction of the longitudinal axis of the coils is avoided.
- connection could be made by an adhesive.
- the windings are advantageously arranged horizontally and one above the other. As a result, slipping of the windings is avoided.
- the coils are interconnected.
- the position of the coils relative to each other is maintained even with strong vibrations.
- the coils are glued together.
- an arrangement comprises a transformer of the type described here and a vehicle having a base, wherein the coils are oriented horizontally to the base or a driving plane.
- the transformer described here is preferably used in rail vehicles, namely in railway operation. In railway operation, particularly strong vibrations occur, so that the transformer described here is particularly suitable for this use.
- the carrying device can advantageously with a car body of a
- Fig. 1 is a perspective view of a transformer, in which the
- FIG. 1 shows a transformer 1, comprising two coils 2, 3, wherein each coil 2, 3 has a core and a plurality of windings and wherein the coils 2, 3 are held in a support means 4.
- the support means 4 has feet 5, 6 for erecting the support means 4 on a base 7, wherein the longitudinal axes of the coils 2, 3 by setting up the
- Carrying device 4 are horizontally oriented on the base 7.
- the longitudinal axes are arranged parallel to each other and horizontally.
- the feet 5, 6 have means 8, namely passages, for fixing the
- the support device 4 has two spaced-apart feet 5, 6, wherein each of the feet 5, 6 a pressing beam 9, 10 protrudes and wherein the coils 2, 3 extending between the pressing bars 9, 10.
- Fig. 2 shows that a press beam 9, 10 with struts 1 1 and / or
- FIG. 2 further shows that the feet 5, 6 are connected by a central strut 12 with each other.
- the center strut 12 extends parallel to the longitudinal axes of the coils 2, 3.
- the windings of a single coil 2, 3 are connected to each other and / or to the core to avoid bending or slipping.
- the windings are horizontal and arranged one above the other.
- the coils 2, 3 are also connected to each other.
- the known from Fig. 1 transformer 1 is advantageous on a vehicle having a base 7, wherein the coils 2, 3 are oriented horizontally to the base 7 or a driving plane, can be arranged.
- the vehicle can be designed as a rail vehicle.
