Description

Kerntransformator für Luft- und' Ölkühlung; wobei die die Spulenpressung ausübenden Preßstücke am Eisenkern befestigt sind. Die bisherigen Konstruktionen vertikaler Kerntransformatoren haben den Nachteil, daß die Spulenpreßkraft und die jochpreßkraft in gleicher Richtung und vom gleichen Konstruktionselement aufgenommen werden.Core transformer for air and oil cooling; where the the coil pressure exercising pressed pieces are attached to the iron core. The previous constructions vertical core transformers have the disadvantage that the coil pressing force and the yoke press force added in the same direction and from the same structural element will.

Wegen der kurzschlußsicheren Lagerung der Spulenwindungen gegeneinander und gegen die Eisenkerne ist ein festes Zusammenpressen der ganzen Spulen in ,der Richtung des Spuleneisenkernes erforderlich.Because of the short-circuit-proof mounting of the coil windings against each other and against the iron cores there is a firm compression of the whole coils in the Direction of the coil iron core required.

Um nun zu verhindern, daß der Spulenpreßdruck und der Befestigungsdruck zwischen Jocht- und Kerneisen an dessen Stumpfstoßverhind'ungen sich gegenseitig beeinflußen, wird nach vorliegender Erfindung der Spulendruck direkt auf einen in Richtung des Kraftflusses ungeteilten Teil des Spuleneisenkernes übertragen durch die mit dem, Spuleneisenkern vernieteten Deckplatten a.Now, in order to prevent the spool pressing pressure and the fastening pressure between yoke and core iron at its butt joint prevention each other influence, according to the present invention, the coil pressure is directly applied to an in Direction of power flow transmitted through undivided part of the coil iron core the cover plates riveted to the coil iron core a.

Eine konstruktive Ausführungsmöglichkeit zeigt die beiliegende Zeichnung. Die in Richtung des Kraftflusses ungeteilten Deckplatten a sind an ihren oberen und unteren Enden nach außen hakenförmig umgebogen. In den hierdurch entstandenen Haken sind Winkeleisen b eingelegt, die mit ihren horizontalen Schenkeln auf .den Transformator-Wicklungsspulen c aufsitzen, so daß die achsiale Dehnung der Wicklung direkt auf den mit a verbundenen ungeteilten Teil :des Spuleneisenkerns übertragen wird.The attached drawing shows a constructive implementation option. The cover plates a, which are undivided in the direction of the flow of force, are at their upper ones and lower ends bent outwards like a hook. In the resulting Hooks angle irons b are inserted, the .den with their horizontal legs Transformer winding coils c sit on, so that the axial expansion of the winding transferred directly to the undivided part connected to a: of the coil iron core will.

Durch die Querverbindungen d mit den Keilen e wird; ferner einerseits eine gute Versteifung der Winkeleisen untereinander erreicht, anderseits wird der ganze durch Ventilationsschlitze unterteilte Transformatoren-Eisenblechkörper zusammengehalten.Through the cross connections d with the wedges e is; further on the one hand a good stiffening of the angle irons among each other is achieved, on the other hand the whole sheet metal transformer bodies, divided by ventilation slots, held together.

Die Schrauben g pressen die Stoßstellen f der Eisenkern- und Jochblechpakete gegeneinander, so daß ein guter magnetischer Schluß im Eisenkörper gewährleistet wird.The screws g press the joints f of the iron core and yoke stacks against each other, so that a good magnetic connection in the iron body is guaranteed will.
