Description

Ölbehälter für Transformatoren und ähnliche ölgekühlte elektrische Apparate, deren Seitenwände ganz oder teilweise. aus Wellblech bestehen und durch an der Grundplatte angreifende Tragstangen beim Anheben des Behälters von Zug entlastet sind. Behälter für Öltransformatoren und ähnliche ölgekühlte elektrische Apparate erhalten vielfach zur Abführung der Verlustwärme Wellblechwände. Die übliche Konstruktion dieser Wellblechkessel ist so, daß der aus verhältnismäßig dünnem Kesselblech autogen geschweißte Kasten auf einer schweren Gußeisen- oder Profileisenplatte ruht. An vier zweckentsprechenden Stellen sind dann Tragbolzen hochgeführt, auf denen Ösen zum Hochheben des ganzen Transformators engebracht sind. Als Dichtungsboden des Gefäßes kann aus schweißtechnischen Gründen nur ein mit dem Wellblech ungefähr gleich starkes Blech genommen werden. Deshalb muB die Grundplatte so- kräftig und entsprechend schwer ausgeführt sein, daß sie z. B. beim Hochheben des Transformators - den Bodendruck und auch das Gewicht des im Kastenstehenden Transformatorkernes aufnehmen kann.Oil tanks for transformers and similar oil-cooled electrical ones Apparatus, the side walls of which in whole or in part. consist of corrugated iron and through Supporting rods acting on the base plate are relieved of tension when the container is lifted are. Containers for oil transformers and similar oil-cooled electrical apparatus are often provided with corrugated iron walls to dissipate the heat loss. The usual construction this corrugated iron boiler is such that the one made of relatively thin boiler sheet is autogenous welded box rests on a heavy cast iron or profile iron plate. At four appropriate points are then raised support bolts on which eyelets to lift the whole transformer. As the sealing base of the For welding reasons, the vessel can only be roughly the same as the corrugated iron thick sheet metal can be used. That is why the base plate must be strong and appropriately be made difficult that they z.

Die Erfindung bezieht sich auf einen Kessel, bei dem -durch Ausnutzung des- aus anderen Rücksichten sehr kräftigen oberen Kastenrahmens zur Aufnahme des Bodendruckes eine Entlastung der Grundplatte erreicht wird, so daß letztere wesentlich leichter wie bei der eingangs beschriebenen Ausführungsart gehalten werden kann. Dies geschieht, indem zwischen Grundplatte und oberem Kastenrahmen eine größere Anzahl von Zugbolzen in solchen Abständen ange-_ ordnet sind, datß eine wesentliche Durchbiegung der Grundplatte zwischen je zwei Zugbolzen .nicht eintreten kann. Es ist infolgedessen möglich, als Grundplatte eine Blech-- oder schwache Gußplatte zu nehmen. Bei Verwendung einer Blechplatte als Kastenunterlage kann es natürlich erforderlich werden, daß die Fläche der Platte gegen Durchbiegung versteift werden muß. Allgemein dürften hierbei aber einige Profileisenstücke genügen, so daß das Gewicht der Unterlagplatte hierdurch nicht wesentlich erhöht zu werden braucht: In der zugehörigen Zeichnung ist als Unterlage des Kastens a eine Kesselblechplatte b angenommen. Die Bolzen c bilden die Entlastungsverbindung der Grundplatte zum oberen Rahmen d, während e und f Versteifungseisen der Grundplattenfläche sind. Beim Hochheben des Kastens wird an den vier Ösen g angefaßt, die auf vier der Zugbolzen geschraubt sind. Dem Gewicht des gesamten Apparates entsprechend können diese vier Bolzen kräftiger gehalten werden wie die übrigen. Stellt man sich den Kasten an den vier Ösen hängend vor, so ist durch die Bolzen c die Grundplatte b gewissermaßen am Rahmen d aufgehängt, und bei entsprechender Festigkeit des Rahmens d braucht die Grundplatte b nur stark genug zu sein, die zwischen zwei Zugbolzen c wirkende Last aufzunehmen.The invention relates to a boiler in which - by taking advantage of the other considerations - very strong upper box frame to absorb the ground pressure, a relief of the base plate is achieved so that the latter can be held much more easily than in the embodiment described above. This is done by arranging a larger number of tension bolts between the base plate and the upper box frame at such intervals that a significant deflection of the base plate cannot occur between two tension bolts. As a result, it is possible to use a sheet metal or weak cast plate as the base plate. When using a sheet metal plate as a box base, it may of course be necessary that the surface of the plate must be stiffened against bending. In general, however, a few pieces of profile iron should suffice, so that the weight of the base plate does not have to be increased significantly: In the accompanying drawing , a boiler plate b is assumed as the base of the box a. The bolts c form the relief connection of the base plate to the upper frame d, while e and f are stiffening irons of the base plate surface. When lifting the box, the four eyelets g, which are screwed onto four of the tension bolts, are grasped. In accordance with the weight of the entire apparatus, these four bolts can be held more firmly than the others. If one imagines the box hanging from the four eyelets, the base plate b is suspended from the frame d by the bolts c, and if the frame d is sufficiently strong, the base plate b only needs to be strong enough to act between two tension bolts c To take the load.
