Description
<Desc/Clms Page number 1>
Ruhender Frequenztransformator.
Die Erfindung bezieht sich auf eine Anordnung zur Verbesserung der Luftkühlung bei ruhenden Frequenztransformatoren, die im Betriebe bekanntlich stark erwärmt werden. Es ist bereits bekannt, bei Transformatoren oder andern elektrischen Maschinen die Wärme aus dem Blechkörper durch in diesen eingelegte besondere Kühlbleehe, die über den Umfang des Blechkörpers herausragen und aus gut wärmeleitendem Material angefertigt sind, abzuleiten. Die Erfindung betrifft eine Verbesserung dieser Art der Kühlung, die insbesondere bei den sich stark erwärmenden ruhenden Frequenztransformatoren eine wesentlich bessere Wärmeableitung ergibt.
Sie besteht darin, dass die in den Blechkörper eingelegten Kühlbleche über den äusseren Rand der die Wicklung tragenden Schenkel weiter herausragen als über den inneren, dem Fenster zugekehrten Rand, wobei die Wicklungsaehsen gegen die Achsen der von den Wicklungen umschlossenen Eisenquerschnitte nach aussen versetzt sind.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung in Auf-und Grundriss. Der Blech- körper k des ruhenden Frequenztransformators ist durch Kühlbleche 1 unterteilt. Da die Luft nur an den Aussenflanken (etwa in der Richtung der Pfeile 1) axial ungehindert durchstreichen kann, sind
EMI1.1
zugleich zur Distanzierung der Wicklung gegen den Eisenkörper dienen.
PATENT-ANSPRÜCHE :
1. Ruhender Frequenztransformator mit Luftkühlung, dessen Blechpaket von Kühlblechen durchzogen ist, dadurch gekennzeichnet, dass die Kühlbleche über den äusseren Rand der die Wicklung tragenden Schenkel weiter herausragen als über den inneren, dem Fenster zugekehrten Rand.

Frequency transformer at rest.
The invention relates to an arrangement for improving air cooling in the case of static frequency transformers, which are known to be strongly heated in operation. It is already known in transformers or other electrical machines to dissipate the heat from the sheet metal body through special cooling sheets which are inserted into them and which protrude over the circumference of the sheet metal body and are made of a material that conducts heat well. The invention relates to an improvement of this type of cooling, which results in significantly better heat dissipation, especially in the case of the static frequency transformers which heat up to a great extent.
It consists in the fact that the cooling plates inserted in the sheet metal body protrude further beyond the outer edge of the legs carrying the winding than the inner edge facing the window, with the winding axes being offset outwards from the axes of the iron cross-sections enclosed by the windings.
The drawing shows an embodiment of the invention in plan and floor plan. The sheet metal body k of the static frequency transformer is divided by cooling plates 1. Since the air can only pass through axially unhindered on the outer flanks (approximately in the direction of the arrows 1)
EMI1.1
at the same time serve to distance the winding from the iron body.
PATENT CLAIMS:
1. Dormant frequency transformer with air cooling, the laminated core of which is traversed by cooling plates, characterized in that the cooling plates protrude further over the outer edge of the legs carrying the winding than over the inner edge facing the window.
