Description

Reguliertransformator Bei einem bekannten Reguliertransformator besteht der Eisenkern aus wenigstens drei in einer Ebene nebeneinander angeordneten Teilen, von denen die beiden äußeren Jochteile miteinander z. B. durch Gerüstteile verbunden sind und der mittlere Kernbeil gegen die äußeren Jochteile wie ein Schieber zwischen den Wangen seiner Führung verschoben werden kann.Regulating transformer In a known regulating transformer, there is the iron core consists of at least three parts arranged side by side in one plane, of which the two outer yoke parts with each other z. B. connected by scaffolding parts and the middle ax against the outer yoke parts like a slide between the cheeks of his leadership can be moved.

Es ist vorgeschlagen worden, bei einem solchen Transformator denäußeren Jochteilen quer zur Richtung dieser Verschiebung eine gewisse Beweglichkeit gegeneinander zu geben und sie durch Federn an den mittleren Kernteil anzupressen.It has been proposed to use the exterior of such a transformer Yoke parts transverse to the direction of this shift a certain mobility against each other and to press them against the central part of the core by means of springs.

Im Gegensatz dazu sollen nach der Erfindung die ,äußeren, starr miteinander verbundenen Jochteile zu beiden Seiten des mittleren Kernteils durch Luftspalte getrennt werden, die bei der Verschiebung erhalten bleiben.In contrast, according to the invention, the, outer, rigid with each other connected yoke parts on both sides of the central core part through air gaps which are retained during the move.

Hierdurch sollen Betriebsstörungen vermieden werden, die sich bei Reguliertransformatoren der in Rede stehenden Art mit dichtem Schluß zwischen den Jochteilen und dem mittleren Kernteil. daraus ergeben haben, daß die ,aufeinander schleifenden, lamellierten Eisenkörper allmählich die Blechisolation durchscheuern, so daß die Isolation zwischen den .einzelnen Blechen überbrückt wird und in den Kernteilen starke, das Eisenerhitzende und schmelzende Wirbelströme hervorgerufen werden.This is to avoid operational disruptions that arise with Regulating transformers of the type in question with a tight seal between the Yoke parts and the middle core part. have shown that the, on each other abrasive, laminated iron body gradually rub through the sheet metal insulation, so that the insulation between the individual sheets is bridged and in the Core parts caused strong eddy currents that heat up the iron and melt will.

Die Luftweglänge der Luftspalte zu beiden Seiten des mittleren Kernteiles kann. sehr kurz sein, beispielsweise nur einen Bruchteil .eines Millimeters betragen.The air path length of the air gaps on either side of the central core part can. be very short, for example only a fraction of a millimeter.

Die Anordnung bietet gegenüber dem Transformator mit Federung der .äußeren Jochteile auch noch den Vorteil größerer Einfachheit und Festigkeit der Konstruktion. Die Lagerung und Führung des verschiebbaren Kernteiles. kann trotzdem leicht gebaut werden, weil die magnetischen Zugkräfte, die auf den mittleren Kernteil wirken, sich gegeneinander aufheben.The arrangement offers the transformer with suspension . Outer yoke parts also have the advantage of greater simplicity and strength of the Construction. The storage and guidance of the movable core part. can anyway be easily built because of the magnetic tensile forces acting on the middle core part act, cancel each other out.
