Description

Die Erfindung betrifft einen Transformator, umfassend zwei Spulen, wobei jede Spule einen Kern und mehrere Wicklungen aufweist und wobei die Spulen in einer Trageinrichtung gehalten sind.The invention relates to a transformer comprising two coils, each coil having a core and a plurality of windings, and the coils being held in a support device.

Transformatoren, bzw. deren Spulen, werden häufig so aufgestellt, dass deren Längsachsen senkrecht orientiert sind. Hierdurch wird eine relativ hohe Bauhöhe erreicht. Des Weiteren sind Transformatoren üblicherweise nicht so ausgelegt, dass sie starken Vibrationen beschädigungsfrei Stand halten können.Transformers, or their coils, are often set up in such a way that their longitudinal axes are oriented vertically. This achieves a relatively high overall height. Furthermore, transformers are usually not designed in such a way that they can withstand strong vibrations without damage.

In bestimmten Anwendungsfällen besteht jedoch ein Bedarf, einen Transformator in einem Maschinenraum, insbesondere eines Schienenfahrzeugs, anzuordnen. In einem Maschinenraum steht häufig nur ein bestimmter Raum zum Aufbau eines Transformators zur Verfügung. Des Weiteren wird ein Transformator in einem Maschinenraum eines Fahrzeugs unter Umständen erheblichen Vibrationen ausgesetzt.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, there is often only a certain space available for setting up a transformer. Furthermore, a transformer in a machine room of a vehicle may be exposed to considerable vibrations.

Ein Transformator mit einer Trageinrichtung, die die Transformatorspulen hält, ist beispielsweise in WO 2016/038222 A1 gezeigt.A transformer with a support device that holds the transformer coils is shown in, for example WO 2016/038222 A1 shown.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Transformator derart auszugestalten und weiter zu bilden, dass dieser bei niedriger und kompakter Bauweise in einem Fahrzeug eine möglichst lange Betriebsdauer zeigt.The invention is therefore based on the object of designing and developing a transformer in such a way that it has as long an operating time as possible with a low and compact design in a vehicle.

Erfindungsgemäß wird die voranstehende Aufgabe durch einen Transformator mit den Merkmalen des Patentanspruchs 1 gelöst.According to the invention, the above object is achieved by a transformer with the features of claim 1.

Danach ist der eingangs genannte Transformator dadurch gekennzeichnet, dass die Trageinrichtung zwei von einander beabstandete Füße zum Aufstellen der Trageinrichtung auf einer Unterlage aufweist, wobei von jedem Fuß ein Pressbalken abragt und die Spulen sich zwischen den Pressbalken erstrecken, wobei die Längsachsen der Spulen durch Aufstellen der Trageinrichtung auf der Unterlage waagerecht orientierbar sind und die Spulen übereinander angeordnet sind.According to this, the transformer mentioned at the beginning is characterized in that the support device has two spaced feet for setting up the support device on a base, a press beam protruding from each foot and the coils extending between the press beams, the longitudinal axes of the coils being set up by the Carrying device can be oriented horizontally on the base and the coils are arranged one above the other.

Erfindungsgemäß ist zunächst erkannt worden, dass es notwendig ist, bestehende Transformatoren zu verändern, damit diese in einem Maschinenraum von Fahrzeugen, insbesondere von Schienenfahrzeugen, eingesetzt werden können. Darauf ist erkannt worden, dass insbesondere Spannungsabstände in einem engen Bauraum eingehalten werden müssen und der Transformator starken mechanischen Belastungen Stand halten muss. Durch eine geeignete Trageinrichtung können Spulen waagerecht zu einer Unterlage angeordnet werden. Hierdurch wird eine bestimmte Bauhöhe nicht überschritten, auch wenn die Spulen relativ lang sind. Des Weiteren werden die Spulen in der Trageinrichtung gegen Vibrationen gelagert.According to the invention, it was first recognized that it is necessary to change existing transformers so that they can be used in a machine room of vehicles, in particular of rail vehicles. It was then recognized that voltage clearances in particular must be maintained in a tight installation space and that the transformer must withstand strong mechanical loads. By means of a suitable support device, coils can be arranged horizontally on a base. As a result, a certain overall height is not exceeded, even if the coils are relatively long. Furthermore, the coils are stored in the support device against vibrations.

Vorteilhaft weisen die Füße Mittel zum Fixieren der Trageinrichtung auf der Unterlage auf. Die Mittel können als Durchgänge für Schrauben ausgebildet sein. Hierdurch kann der Transformator läge- und verschiebefest mit einem Fahrzeug verbunden werden.The feet advantageously have means for fixing the support device on the base. The means can be designed as passages for screws. In this way, the transformer can be connected to a vehicle in a position-proof and non-displaceable manner.

Die Trageinrichtung weist zwei voneinander beabstandete Füße auf, wobei von jedem Fuß ein Pressbalken abragt und wobei die Spulen sich zwischen den Pressbalken erstrecken. Hierdurch können die Spulen übereinander in der Trageinrichtung gestapelt werden, so dass ihre Längsachsen parallel orientiert sind. Die Spulen können an den Pressbalken festgelegt und gegen Vibrationen gelagert sein,The support device has two feet spaced apart from one another, a press beam protruding from each foot and the coils extending between the press beams. As a result, the coils can be stacked on top of one another in the support device, so that their longitudinal axes are oriented parallel. The coils can be fixed to the press beam and supported against vibrations,

Weiter vorteilhaft ist ein Pressbalken mit mindestens einer Verstrebung und/ oder Verstärkung zur Versteifung versehen. Hierdurch können große Kräfte in oder quer zur Fahrtrichtung des Fahrzeugs kompensiert werden, ohne dass sich die Pressbalken merklich verbiegen. Auch eine Verbiegung bzw. Stauchung der Pressbalken wird vermieden. Des Weiteren wird ein Verschieben der Spulen vermieden.A press beam is also advantageously provided with at least one strut and / or reinforcement for stiffening. In this way, large forces in or across the direction of travel of the vehicle can be compensated without the press beams noticeably bending. Bending or compression of the press beams is also avoided. Furthermore, a shifting of the coils is avoided.

Um große Kräfte in Fahrtrichtung, quer zur Fahrtrichtung und in vertikaler Richtung zu beherrschen, müssen die Verbindungen zur Unterlage, insbesondere einem Wagenboden, in besonderer Weise ausgelegt sein.In order to master 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 vehicle floor, must be designed in a special way.

Vorteilhaft sind die Füße durch eine Mittelstrebe miteinander verbunden. Auch hierdurch können große Kräfte in oder quer zur Fahrtrichtung des Fahrzeugs kompensiert werden, ohne dass sich die Pressbalken merklich verbiegen. Darüber hinaus wird ein Verrutschen der Spulen vorteilhaft vermieden.The feet are advantageously connected to one another by a central strut. In this way, too, large forces in or across the direction of travel of the vehicle can be compensated without the press beams noticeably bending. In addition, slipping of the coils is advantageously avoided.

Die Mittelstrebe erstreckt sich vorteilhaft parallel zu den Längsachsen der Spulen. Hierdurch wird eine Stauchung der Trageinrichtung in Richtung der Längsachse der Spulen vermieden.The central strut advantageously extends parallel to the longitudinal axes of the coils. This avoids compression of the support device in the direction of the longitudinal axis of the coils.

Die Wicklungen einer einzelnen Spule sind vorteilhaft zur Vermeidung eines Durchbiegens oder Verrutschens miteinander und/ oder mit dem Kern der jeweiligen Spule verbunden. Die Verbindung könnte durch einen Klebstoff erfolgen.The windings of an individual coil are advantageously connected to one another and / or to the core of the respective coil in order to avoid bending or slipping. The connection could be made by an adhesive.

Die Wicklungen sind waagerecht und übereinander angeordnet. Hierdurch wird ein Verrutschen der Wicklungen vermieden.The windings are arranged horizontally and one above the other. This prevents the windings from slipping.

Vorteilhaft sind die Spulen miteinander verbunden. So bleibt die Position der Spulen relativ zueinander auch bei starken Vibrationen erhalten. Bevorzugt sind die Spulen miteinander verklebt.The coils are advantageously connected to one another. In this way, the position of the coils relative to one another is retained even in the event of strong vibrations. The coils are preferably glued to one another.

Erfindungsgemäß umfasst eine Anordnung einen Transformator der hier beschriebenen Art und ein Fahrzeug, welches eine Unterlage aufweist, wobei die Spulen waagerecht zur Unterlage oder einer Fahrebene orientiert sind.According to the invention, an arrangement comprises a transformer of the type described here and a vehicle which has a base, the coils being oriented horizontally to the base or a driving plane.

Der hier beschriebene Transformator wird bevorzugt in Schienenfahrzeugen, nämlich im Bahnbetrieb, verwendet. Im Bahnbetrieb treten besonders starke Vibrationen auf, so dass sich der hier beschriebene Transformator besonders für diese Verwendung eignet.The transformer described here is preferably used in rail vehicles, namely in rail operations. Particularly strong vibrations occur in rail operations, so that the transformer described here is particularly suitable for this use.

Die Trageinrichtung kann vorteilhaft mit einem Wagenkasten eines Schienenfahrzeugs verbunden werden. Trotz gegebener Abmessungen, Vibrationen und Massen kann so ein hoher Wirkungsgrad gewährleistet werden und kann Materialermüdung entgegengewirkt werden.The support device can advantageously be connected to a car body of a rail vehicle. Despite the given dimensions, vibrations and masses, a high degree of efficiency can be guaranteed and material fatigue can be counteracted.
