Description

Transformator mit unter Verwendung von ass Isolierstoff bestehenden Abstandsstücken untertei)tem Eisenkern Schlitze parallel zur Blechschichtung von ; Eisenkernen finden häufig, insbesondere zum Zwzcke der Ober,vallenkompeusation wk aa.. zur Verbesserung der Kühlung, Anwendung. Im erstgenannten Falle beispielsweise wird .der Kern häufige geteilt, wobei die teine Hälfte mit einer Stern- -und, -die -andere mit einer Dreieckwicklung ausgerüstet werden,. Zwischen derartigen Kernteilen befinden sich nun im allgemeinen Abstandsstücke, die auf dem Endblech des einen Kernteiles verschraubt sind. Solche Anordnungen erfüllen zwar durchaus ihren Zweck; ihre Herstellung ist jedoch zeitraubend und .kostspielig. Ferner hat man bereits in -die Bleche elektrischer Maschinen Augen eingestanzt, derart, daß in radialer Richtung Dxahts.tücke eingezogen werden konnten. Auch dieses Verfahren ist noch zu teuer, da Stanzmaschinen bertOtigt werden. Außerdem berühren sich die Endbleche der beiden Kernteile, was bei der Oberweilenkompensation unbedingt vermieden werden muß.Transformer with existing insulation material using ass Spacers subdivided iron core slots parallel to the sheet metal layering of ; Iron cores often find vallenkompeusation, especially for the purpose of the upper, vallenkompeusation wk aa .. to improve cooling, application. In the former case, for example the core is frequently divided, the one half being marked with an asterisk - and - the - others can be equipped with a triangular winding. Between such core parts are now generally spacers that are on the end plate of the one Core part are screwed. Such arrangements certainly serve their purpose; however, their production is time-consuming and costly. Furthermore, one already has -in-the sheets of electrical machines eyes punched in such a way that in radial Direction Dxahts.tücke could be drafted. This procedure is also still in progress too expensive as punching machines are obsolete. In addition, the end plates touch of the two core parts, which must be avoided in the case of the Oberweiler compensation got to.

Die Erfindung schlägt daher vor, die aus Isolierstoff bestehenden Abstandsstücke auf einer Endplatte aus leicht hearbeitbarem Material -des einen Endpaketes durch Falze in ihrer Lage zu halten. Zäßig zlieat hierzu eine Platte aus .Wärme gut leitendem Material, wie Aluminium. Auch ist es möglich, insbesondere bei kleineren Einheiten, hierzu wie auch für die Abstandsstücke Preßspan zu verwenden.. Ausführungsbeispiele der erfindungsgemäßen Anordnung sind in den. Abb. i bis 3 der Zeichnung dargestellt. Hierbei zeigt die Abb. i einen Querschnitt durch einen Schenkel. Auf der einen der einander zugekehrten Seiten der Schenkelteile a und b befindet sich die Platte bzw. das Endblech c. Vier Abstandsstücke d, die sich etwa über die gesamte Schenkellänge erstrecken mögen, sind zwischen den beiden Kernteilen vorgesehen, die durch eine Schraube e zusammengehalten werden.The invention therefore proposes that consisting of insulating material Spacers on an end plate made of easily machinable material - one of them To hold the final package in place by folding. A record is added to this Made of .heat conductive material such as aluminum. It is also possible, in particular for smaller units, press chipboard to be used for this as well as for the spacers .. Embodiments of the arrangement according to the invention are shown in. Fig. I to 3 of the Drawing shown. Here, Fig. I shows a cross section through a leg. Located on one of the facing sides of the leg parts a and b the plate or the end plate c. Four spacers d that extend approximately over the may extend the entire leg length, are provided between the two core parts, which are held together by a screw e.

Die Anordnung der Abstandsstücke ist in der Abb..2 in vergrößertem Maßstabe wiedergegeben. Hiernach umgreift ein Doppelfalz das Stück d, das gegebenenfalls noch mit der ,Platter verklebt ist.The arrangement of the spacers is enlarged in Fig..2 Scale reproduced. A double fold then encompasses piece d, which may be still glued to the platter.
