Description

Federnde Abstützvorrichtung für die Wicklungen von Transformatoren. Durch die Patentschrift 324226 ist eine federnde Abstützvorrichtung für Transformatorwicklungen bekannt, geworden, bei welcher zwischen die Wicklung und ihr Widerlager ein Katarakt eingeschaltet ist, der die mechanischen Kräfte bei Kurzschlüssen aufnimmt, während die selbsttätige Rückführung des Katarakts durch Federn erfolgt, die ebenfalls zwischen Wicklung und Widerlager eingeschaltet sind. 1 Bei Transformatoren mit mehreren konzentrischen Wicklungen von verschiedenartigem Aufbau, der auch ungleiches Setzen der Wicklungen zur Folge hat, verwendet man zweckmäßig mehrere federbelastete Kata rakte, wie in der genannten Patentschrift angegeben. Auch bei dieser Anordnung sind jedoch die verschiedenen Wicklungen nicht dauernd gleich stark gepreßt. Wenn nämlich die Wicklungen sich setzen, so können die Federn sich ausdehnen und werden dadurch entlastet. Die Pressung einer jedenWicklung nimmt also unabhängig von der der anderen Wicklungen um so stärker ab, je mehr die betreffende Wicklung sich setzt. Ein weiterer Nachteil der Anordnung mit gespannten, federMasteten Katarakten ist der, daß man für jede Wicklung ein besonderes System von Katarakten und Federn anwenden muß.Spring support device for the windings of transformers. A resilient support device for transformer windings is known from patent specification 324226, in which a cataract is connected between the winding and its abutment, which absorbs the mechanical forces in the event of short circuits, while the automatic return of the cataract takes place by springs, which are also between the winding and Abutments are switched on. 1 In transformers with several concentric windings of different structures, which also results in unequal setting of the windings, it is advisable to use several spring-loaded Kata rakts, as indicated in the patent mentioned. Even with this arrangement, however, the various windings are not constantly pressed to the same degree. When the windings settle, the springs can expand and are thereby relieved. The pressure of each winding therefore decreases, independently of that of the other windings, the more the winding in question settles. Another disadvantage of the arrangement with tensioned, spring-masted cataracts is that a special system of cataracts and springs must be used for each winding.

Erfindungsgemäß soll nun für zwei konzentrische Wicklungen nur ein gemeinsames System von Katarakten und Federn verwendet und der Kolbendruck durch Zwischenschaltung von Hebeln auf beide Wicklungen übertragen werden.According to the invention, only one should now be used for two concentric windings common system of cataracts and springs used and the piston pressure through Interposition of levers can be transferred to both windings.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung. Sie stellt einen Schnitt durch zwei auf einem Kern konzentrisch angeordnete Wicklungen dar.The figure shows an embodiment of the invention. She poses a section through two concentrically arranged windings on a core.

Es bedeuten a, a" die letzten Transformatorspulen, b, b, die Endringe für die beiden Wicklungen, c den mit einer Feder belasteten Kolben des Katarakts. Die auf diesen Kolben ausgeübte Druckkraft wird durch den Hebel h auf beide Wicklungen übertragen. Der Hebel -kann in gestreckter Hebel oder ein WinkelhF,bel sein. Es kann auch ein Kniehebel verwendet werden. Durch diese Anordnung wird erreicht, daß die Pressung beider Wicklungen nur gemeinsam im gleichen Verhältnis abnehmen kann. Außerdein. wird dadurr-1 die Anordnung getrennter Kataraktsysteme für jede Wicklung erspart. Der Hebel h kann auch in Pfannen gelagert sein.It means a, a "the last transformer coils, b, b, the end rings for the two windings, c the piston of the cataract loaded with a spring. The compressive force exerted on this piston is transmitted to both windings by the lever h. can be in an extended lever or an angled lever. A toggle lever can also be used. This arrangement ensures that the pressure of both windings can only decrease together in the same ratio. In addition, there is the arrangement of separate cataract systems for each The lever h can also be stored in pans.
