Description

Öltransformatorgehäuse mit durch Scheidewände von dem Transformator getrennten Kühltaschen. Um bei Öltransformatoren das Öl möglichst gut zu kühlen, hat man an den Transformatorwänden Kühltaschen angebracht, die die Abkühlungsfläche des Gehäuses beträchtlich vergrößern. Bei dieser Anordnung wird das abgekühlte Öl indessen dem unteren Teil der Wicklung nicht gut zugeführt, da ihm j a der Weg zur Rückkehr schon früher zur Verfügung steht. Eine bessere Kühlung des unteren Teiles der Wicklung kann man dadurch erhalten, daß man zwischen dem Transformator und der Innenwand des Gehäuses Scheidewände anordnet, die dem Öl den gewünschten Weg vorschreiben. Solche Scheidewände hat man bereits verwendet, um eine bessere Wärmeabgabe des Öles an die Gehäusewand zu erreichen. Die Scheidewände bestehen aus Blechen, die zwischen dem Transformator und der inneren Wand des Gehäuses angeordnet sind und mit Führungsblechen versehen sind, die das Öl zwingen, in unmittelbarer Nähe der Innenwand der Kühltaschen vorüberzufließen. Das am Transformator in die Höhe gestiegene 01 fließt in diesem Fall über den oberen Rand der Scheidewände den Kühltaschen zu, sinkt unmittelbar an deren Innenwänden herab und fließt von dem unteren Ende der Kühltaschen durch von den Scheidewänden und den Gehäusewänden gebildete Kanäle aus den Kühltaschen ab.Oil transformer housing with cooling pockets separated from the transformer by partitions. In order to cool the oil in oil transformers as well as possible, cooling bags have been attached to the transformer walls, which considerably increase the cooling surface of the housing. With this arrangement, however, the cooled oil is not well fed to the lower part of the winding, since the way to return is already available to it earlier. Better cooling of the lower part of the winding can be obtained by arranging partitions between the transformer and the inner wall of the housing which dictate the desired path for the oil. Such partitions have already been used to achieve better heat dissipation from the oil to the housing wall. The partitions consist of metal sheets which are arranged between the transformer and the inner wall of the housing and are provided with guide sheets which force the oil to flow past in the immediate vicinity of the inner wall of the cooling bags. The 01 , which has risen in height on the transformer, flows in this case over the upper edge of the partition walls to the cooling bags, sinks directly down the inner walls and flows from the lower end of the cooling bags through channels formed by the partition walls and the housing walls from the cooling bags.

Diese bekannte Anordnung wird nach der Erfindung dadurch -wesentlich vereinfacht, daß als Scheidewände Bleche verwendet werden, die innen an den Wellen der Kühltaschen derartig dicht anliegen, daß die durch das Blech frei gelassenen Öffnungen für den Öldurchfluß unmittelbar in die Kühltaschen münden. In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Fig. z zeigt einen Vertikalschnitt, Fig. 3 einen Horizontalschnitt einesTransformatorgehäuses g, das den Transformator t enthält, und -das- an den Wänden mit Kühltaschen k versehen ist. An den Wellen der Kühltaschen liegen innerhalb des Transformatorgehäuses nach der Erfindung Bleche b an, und zwar so, daß für den Oldurchfluß Öffnungen o und u vorhanden sind, die unmittelbar in die Kühltaschen münden. Während in dem Beispiel nach Fig. r die Öffnungen in den Blechen selbst angebracht sind, werden sie in dem Beispiel nach Fig. a dadurch erzeugt, daß das Blech kürzer als die Länge der Kühltaschen gewählt ist. Der zweite Fall ermöglicht eine besonders einfache und billige Ausführung der Erfindung.This known arrangement becomes essential according to the invention Simplified that sheets are used as partitions, the inside of the shafts the cooling bags are so tight that the ones left free by the sheet metal Openings for the oil flow open directly into the cooler bags. In the drawing two embodiments of the invention are shown. Fig. Z shows a vertical section, Fig. 3 is a horizontal section of a transformer housing g which houses the transformer t contains, and -that- is provided with cooling pockets k on the walls. On the waves the cooling bags are within the transformer housing according to the invention sheets b on, in such a way that openings o and u are present for the oil flow open directly into the cooler bags. While in the example of Fig. R, the openings Are attached in the sheets themselves, they are in the example of Fig. a thereby generated that the sheet is chosen to be shorter than the length of the cooling bags. The second Case enables a particularly simple and inexpensive implementation of the invention.

Die Bleche werden zweckmäßig an dem inneren Wellenrand v der Blechwand des Transformatorgehäuses befestigt. Die Befestigung der Bleche am Transformatorgehäuse geschieht am einfachsten durch Punktschweißung.The sheets are expediently on the inner corrugated edge v of the sheet metal wall attached to the transformer housing. The attachment of the metal sheets to the transformer housing The easiest way to do this is by spot welding.
