Description

Verfahren zum öldichten Einsetzen von Durchführungen im Boden von Ölschaltertöpfen Bei Ölschaltern, bei denen die Anschlußkontakte sich im Boden des Öltopfes befinden, treten Schwierigkeiten auf, die den Topf durchsetzenden Porzellanteile öldicht in den Boden einsetzen zu können. Die hierfür verwendeten Kitte werden mit der Zeit mehr oder weniger öldurchlässig. Nach dem vorliegenden Verfahren wird ein öldichtes Einsetzen der Porzellandurchführungen dadurch erreicht, daß zunächst der in dem Flanschteil des Öltopfbodens sitzende Teil der Durchführung verkupfert wird. Darauf wird in bekannter Weise durch eine niedrige Kittschicht die Durchführung in den Boden eingekittet und dann der überflüssige Raum zwischen der Durchführung und dem Topfflansch mit einer leicht schmelzbaren Metallmasse ausgefüllt, die einerseits mit dem Flansch, andererseits mit dem verkupferten Durchführungsteil eine so innige Verbindung eingeht, daß ein Durchlassen von C51 unmöglich wird. Als Metallnasse könnte irgendeine Metallegierung verwendet werden, deren Schmelzpunkt etwa ioo bis i5o° ist, so daß sie bei den vorkommenden Olschalterbelastungen nicht mehr weich werden kann. Die zuerst eingeführte niedrige Kittschicht soll nur dazu dienen, das Eingießen der flüssig gemachten Metallverbindung zu ermöglichen.Method for the oil-tight insertion of bushings in the bottom of Oil switch pots For oil switches where the connection contacts are in the bottom of the Oil pot are, difficulties arise in the porcelain parts penetrating the pot To be able to use oil-tight in the ground. The putties used for this are with more or less oil permeable over time. According to the present procedure, a Oil-tight insertion of the porcelain bushings achieved in that initially the in the flange part of the oil pot bottom seated part of the implementation is copper-plated. The implementation is then carried out in a known manner through a low layer of putty cemented into the ground and then the superfluous space between the implementation and the pot flange filled with an easily meltable metal mass, which on the one hand with the flange, on the other hand with the copper-plated bushing part so intimate Connection comes in that it is impossible to let C51 through. As metal wet any metal alloy having a melting point of about 100 to i5o °, so that it is no longer soft with the occurring oil switch loads can be. The first introduced low layer of putty is only intended to serve that To enable pouring of the liquefied metal compound.

In der Zeichnung bezeichnet a den Olschaltertopf, b ist die Porzellandurchführung, die auf ihrer Oberfläche mit einem Kupferniederschlag c versehen ist. d ist die dünne Kittschicht, e die eingegossene Metallegierung. An Stelle des direkten Einsetzens der Durchführung in den Ölschaltertopf kann auch die Durchführung in einen Flansch eingesetzt werden, der seinerseits mit dem Öltopf- öldicht befestigt wird.In the drawing, a denotes the oil switch pot, b is the porcelain bushing, which is provided with a copper deposit c on its surface. d is the thin layer of cement, e the cast metal alloy. Instead of inserting it directly the implementation in the oil switch pot can also be implemented in a flange be used, which in turn is fastened with the oil pot oil-tight.

PATENTANSPRUCH Verfahren zum öldichten Einsetzen von Durchführungen im Boden von Ölschaltertöpfen, dadurch gekennzeichnet, daß der innerhalb des Bodenflansches befindliche Durchführungsteil auf seiner Außenseite verkupfert wird und dann in bekannter Weise mittels einer niedrigen Kittschicht befestigt und der übrige Raum zwischen Durchführung und Flansch mit einer bei niedriger Temperatur schon flüssig werdenden Metallegierung ausgegossen wird, die eine öldichte Verbindung zwischen der verkupferten Durchführung und dem Flansch bewirkt.PATENT CLAIM Method for the oil-tight insertion of bushings in the bottom of oil switch pots, characterized in that the inside the bottom flange located bushing part is copper-plated on its outside and then in known way fixed by means of a low layer of putty and the rest of the space between bushing and flange with an already liquid at low temperature to be poured metal alloy, which creates an oil-tight connection between the copper-plated bushing and the flange.
