Description
Anzapfumsteller von Transformatoren, haben den. Zweck, über Anzapfüngen Wicklungsteile zu- oder abzuschalten, um andere Spannungen einstellen zu können. Bekanntlich werden dabei die Umsteller am Deckel des Transformators, gegebenenfalls unter gleichzeitiger Abstützung am Kern,. befestigt und durch eine durch den. Kessel hindurchgeführte Welle von oben betätigt. Bei Drehstromtransformatoren höherer Spannungen wird aber der größte Teil des Platzes auf dem Deckel schon von den. großen. Befestigungsflanschen der Durchführungen eingenommen., so daß der Umsteller nur bei entsprechender Vergrößerung des Deckels und des Kessels untergebracht werden kann. Außerdem ergeben sich noch Schwierigkeiten. wegen, des notwendigen Abstandes der Welle des. Umstellers von dem in das Öl des Kessels hineinragenden Teil der Durchführung.Tapping converters for transformers have the. Purpose, about taps Switch winding parts on or off in order to be able to set other voltages. As is known, the changeover switches on the cover of the transformer, if necessary with simultaneous support on the core. attached and through a through the. boiler Passed shaft actuated from above. For three-phase transformers with higher voltages but most of the space on the lid is already used by the. huge. Mounting flanges of the bushings occupied., so that the diverter only with appropriate enlargement the lid and the kettle can be accommodated. In addition, there are still Trouble. because of the necessary distance between the shaft of the diverter from the part of the bushing that protrudes into the oil of the boiler.
Diese Schwierigkeiten, und Nachteile werden erfindungsgemäß dadurch vermieden, daß der Umsteller ausschließlich an dem Kern, insbesondere den Jochen des Transformators, befestigt und der Antrieb an die Unterseite des Umstellers herangeführt ist. Die Umsteller werden dabei so tief im Kessel befestigt, daß sie außerhalb der erforderlichen Schlagweite unter Öl von den Durchführungen angeordnet sind.These difficulties and disadvantages are thereby made in accordance with the invention avoided that the diverter only on the core, in particular the yokes of the transformer, and the drive is brought up to the underside of the diverter is. The diverter are fixed so deep in the boiler that they are outside the required distance under oil from the bushings are arranged.
Nachfolgend wird die Erfindung. an Hand der Zeichnung noch näher beschrieben.The following is the invention. described in more detail on the basis of the drawing.
Der Transformator mitWicklung i und Kasten 2 trägt auf dem Deckel 4 vier Durchführungen. 3, die an der Netzspannung angeschlossen sind. Die Spannung wird geändert durch die Umsteller 5, von denen; hier zwei Stück gezeichnet sind. Ihre Befestigung geschieht an den Jochen 6 des Transformators. Die Kontakte 7 sind gegen die Joche 6 und die Antriebsteile 8 entsprechend den: Spannungen isoliert.The transformer with winding i and box 2 carries on the cover 4 four leadthroughs. 3, which are connected to the mains voltage. The voltage is changed by the diverter 5, of which; here two pieces are drawn. They are attached to the yokes 6 of the transformer. The contacts 7 are against the yokes 6 and the drive parts 8 according to the: voltages isolated.
Wie die Zeichnung zeigt; sind die Umsteller in ihrer Lage unabhängig vors den Durchführungen; sie können, sogar unter diesen angeordnet werden. Der Antrieb erfolgt zweckmäßig unten, z. B. über den Kegelradtrieb, 9. In dem gezeichneten Ausführungsbeispiel erfolgt die Betätigung von außen über das Handrad i0 und die Wellen, i i und 1.2, die durch den Deckel zu den Umstellern führen. Der Antrieb könnte auch in Verlängerung der Welle 12 durch die Kastenwand 13 oder eine andere geeignet erscheinende Stelle erfolgen, z. B. auch durch den Kastenboden.As the drawing shows; the diverter are independent in their position in front of the implementation; they can be arranged even under these. The drive takes place appropriately below, z. B. via the bevel gear, 9. In the illustrated embodiment it is operated from the outside via the handwheel i0 and the shafts i i and 1.2, which lead through the cover to the diverter. The drive could also be extended of the shaft 12 through the box wall 13 or another suitable location take place, e.g. B. also through the box bottom.
