Description

Gasdichte, elektrische Durchführung mit Druckgasfüllung und Steuerelektroden Es wurden bereits Vorschläge gemacht, die Steuerelektroden in die Wandung des Gehäuses einzugießen. Dabei zeigte es sich, daß das Eingießen großer Elektroden zu Spaltenbildungen zwischen Metall und Isolierstoff Anlaß gibt. Diese Spaltenbildungen sind auf die verschiedenen Temperaturkoeffizienten von Isoliermaterial und Metall zurückzuführen. Nachteile dieser Art werden durch die Erfindung behoben.Gas-tight, electrical feedthrough with pressurized gas filling and control electrodes Proposals have already been made to insert the control electrodes into the wall of the housing pour in. It was found that pouring in large electrodes leads to the formation of gaps between metal and insulating material. These crevices are due to the different temperature coefficients of insulating material and metal. Disadvantages of this type are eliminated by the invention.

Die Erfindung betrifft eine gasdichte, elektrische Durchführung mit Druckgasfüllung und Steuerelektroden, die im Gehäuse befestigt sind.The invention relates to a gas-tight, electrical bushing with Pressurized gas filling and control electrodes, which are fixed in the housing.

Die Erfindung besteht darin, daß an der Innenwand des Gehäuses zentrisch liegende Ringe mit Gewinde eingegossen sind, an denen die Steuerelektroden angeschraubt sind. Gemäß einer Weiterbildung der Erfindung sind die zentrisch liegenden Ringe höchstens bis zum Beginn der inneren Rundung eingegossen.The invention consists in that centrally on the inner wall of the housing lying rings with thread are cast in, to which the control electrodes are screwed are. According to a further development of the invention, the centrally located rings are Poured in at most up to the beginning of the inner rounding.

Die Erfindung wird an Hand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail using an exemplary embodiment.

Die Figur zeigt eine gasdichte Durchführung im Schnitt. 1 ist das aus Kunstharz gegossene kegelförmige Gehäuse der Durchführung. In der Mitte befindet sich der Stromleiter 5. Dieser ist am oberen Ende in die Kunstharzmasse eingegossen. Das andere Ende ist in eine abmontierbare Distanzierkappe 2 aus Kunstharz eingesetzt. Der äußere Rand weist einen nur wenige zehntel Millimeter kleineren Durchmesser auf als der Innenrand des Befestigungsflansches 6.The figure shows a gas-tight bushing in section. 1 is that conical housing of the bushing, cast from synthetic resin. Located in the middle the current conductor 5. This is cast into the synthetic resin mass at the upper end. The other end is inserted into a removable spacer cap 2 made of synthetic resin. The outer edge is only a few tenths of a millimeter smaller in diameter on than the inner edge of the mounting flange 6.

An der Innenwand des Isoliergehäuses 1 sind nun zentrisch liegende Ringe 3 eingegossen. Diese weisen Gewinde 3 a auf, an denen die Steuerelektroden 4 angeschraubt sind. Das Eingießen oder Umgießen der Ringe erfolgt höchstens so weit, als der Beginn der inneren Rundung 3 b der Ringe nicht mit eingegossen wird. Auf diese Weise werden Spalte zwischen Ring und Isolierwandung beim Gießen und Erkalten vermieden, weil der Ausdehnungskoeffizient der Isoliermasse größer ist als der Ausdehnungskoeffizient des Metalls, z. B. Eisen.On the inner wall of the insulating housing 1 are now centrally located Rings 3 cast. These have thread 3 a on which the control electrodes 4 are screwed on. The rings are poured in or cast around in this way at most far as the beginning of the inner rounding 3 b of the rings is not poured in. In this way there are gaps between the ring and the insulating wall when pouring and cooling avoided because the expansion coefficient of the insulating compound is greater than the expansion coefficient of the metal, e.g. B. iron.

Die Erfindung bietet den Vorteil, daß die Steuerelektroden ein- und ausgebaut werden können. Dadurch werden die Montage und die spätere Wartung der Anlage, sowie auch die Herstellung des Isolierkörpers erleichtert und verbilligt.The invention offers the advantage that the control electrodes and can be expanded. This will facilitate the assembly and subsequent maintenance of the Plant, as well as the production of the insulator is made easier and cheaper.
