Die Erfindung betrifft die Stromzuführung für den axial verschiebbaren Kontaktbolzen eines Vakuumschalters, bestehend einerseits aus einem in einem flüssigen Medium angeordneten Multilamellenkontakt aus einer zylindrischen Hülse, deren Innenseite mit in axialer Richtung verlaufenden Kontaktlamellen ausgekleidet ist, sowie andererseits aus einem zylindrischen Gegenkontakt, der in den Multilamellenkontakt hineinragt und mit seiner Außenseite an den Kontaktlamellen anliegt.The invention relates to the power supply for the axially displaceable contact bolt of a vacuum switch, consisting on the one hand of a multi-lamella contact arranged in a liquid medium from a cylindrical sleeve, the inside of which is provided with contact blades extending in the axial direction is lined, and on the other hand from a cylindrical mating contact, which is in the multi-lamellar contact protrudes and rests with its outside on the contact lamellas.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is in Drawing shown.

Der aus dem Gemüse eines Vakuumschalters herausra^ende bewegliche Kontaktbolzen 1 trägt an der Vorderseite den Gegenkontakt 3, der mit Hilfe einer Mutter auf dem Kontaktbolzen 1 befestigt ist. Der Geeenkontakt 3 ist als Hohlzylir.der ausgebildet Mit seiner Außenseite berührt er die Kontaktlamellen 4, die an der Innenseite einer zylindrischen Hülse 2 aneeordnet sind. Durch das Zusammenwirken der Hülse 2 mit dem Hohlzylinder des Gegenkontaktes 3 entsteht ein Hohlraums, der durch die Hubbewegungen des Kontaktbolzcns 1 beim Schalten vergrößert bzw. verkleinert wird. Dabei entsteht jedesmal em «Istrom der die Zwischenräume zwischen den Kontaktlamellen 4 von ölsghlamm frei hält. Auf diese Weise sind die Kontaktlamellen 4 stets unmittelbar von reinem Transformatorenöl umspült, so daß ihre •Kühlung immer gewährleistet ist.The one sticking out of the vegetables on a vacuum switch movable contact pin 1 carries the mating contact 3 on the front, which with the help of a Nut is attached to the contact bolt 1. The Geeenkontakt 3 is designed as a hollow cylinder with on its outside it touches the contact blades 4, which are arranged on the inside of a cylindrical sleeve 2 are. The interaction of the sleeve 2 with the hollow cylinder of the mating contact 3 a cavity is created which is enlarged by the stroke movements of the contact bolt 1 when switching or is reduced. Each time there is an Icurrent in the spaces between the contact lamellas 4 keeps oil sludge free. In this way, the contact blades 4 are always immediate surrounded by pure transformer oil, so that • it is always cooled.
