Description

VakuumschalterVacuum switch

Die Erfindung bezieht sich auf einen in einem gasdicht ausgebildeten und evakuierten Gefäß angeordneten Schalter, insbesondere einen Hochvakuumschalter, und besteht darin, daß der bewegliche, vorzugsweise keilförmig ausgebildete Kontakt des Schalters mit Hilfe eines im Innern des Gefäßes angeordneten, magnetisch oder elektrisch durch die Gefäßwandung hindurch angetriebenen Schraubengetriebes betätigt wird.The invention relates to a gas-tight and evacuated one Vessel arranged switch, in particular a high vacuum switch, and consists in that the movable, preferably wedge-shaped contact of the switch with the help one arranged inside the vessel, magnetically or electrically through the vessel wall driven through screw gear is operated.

Es ist zwar bereits bekannt, bei einem Vakuumschalter elektromagnetisch durch die Wandung des Gefäßes einen axial verschiebbaren Kontaktträger zu steuern. Dieser Schalter hat aber den Nachteil, daß der Kontakt beim Schalten verhältnismäßig hart aufschlägt, wodurch die meist aus Glas bestehende Gefäßwand auf Stoß äußerst stark beansprucht wird und bei häufigem Schalten leicht zersprengt werden kann.It is already known for one Vacuum switch electromagnetically through the wall of the vessel an axially displaceable To control contact carrier. This switch has the disadvantage that the contact hits relatively hard when switching, causing the mostly made of glass The vessel wall is extremely heavily stressed on impact and with frequent switching can be easily burst.

Demgegenüber wird bei der Erfindung der bewegliche Kontakt durch ein im Innern des Vakuumgefäßes vorgesehenes Schraubengetriebe, das durch die Gefäßwand hindurch magnetisch oder elektrisch betätigt wird, gesteuert. Dadurch wird mit Sicherheit ein hartes Aufschlagen des Kontaktes vermieden. Außerdem kann die Kraft, mit der der bewegliche Kontakt gegen den feststehenden in der Einschaltstellung des Schalters gepreßt wird, verhältnismäßig hoch gewählt werden.In contrast, in the invention, the movable contact by an inside the Vacuum vessel provided screw gear that passes through the vessel wall operated magnetically or electrically controlled. This will certainly be a hard hitting the contact avoided. In addition, the force with which the movable Contact is pressed against the fixed in the switched-on position of the switch, are selected to be relatively high.

An Hand des in der Zeichnung dargestellten Vakuumschalters soll die Erfindung näher erläutert werden. Der durch den Elektromagneten 18 angetriebene, im Vakuumgefäß 19 angeordnete, als Kurzschlußläufer ausgebildete Motoranker 20 ist mit seiner teilweise bei 21 spindelförmig ausgebildeten Welle in dem mit einem entsprechenden Gewinde versehenen Lager 22 und mit dem glatten Teil seiner Welle in dem Lager 2.3 gelagert; überdies ist auf der Welle der kegelförmige Kontakt 24 vorgesehen, der bei Drehen des Motorankers 20 in den entsprechend kegelförmig ausgesparten Kontaktring 25 eingepreßt wird und dadurch die Kontaktgabe zwischen der Zuleitung 26 zum Kontakt 25 und zwischen der Zuleitung 27 zum Kontakt 24, die über das Lager 23 zum Kontakt 24 erfolgt, bewirkt.Using the vacuum switch shown in the drawing, the invention is intended to be more detailed explained. The one driven by the electromagnet 18, in the vacuum vessel 19 arranged, designed as a squirrel cage motor armature 20 is with its partial at 21 spindle-shaped shaft in the one with a corresponding thread provided bearing 22 and with the smooth part of its shaft in the bearing 2.3 stored; In addition, the conical contact 24 is provided on the shaft, which at Rotate the motor armature 20 into the correspondingly conically recessed contact ring 25 is pressed in and thereby the contact between the supply line 26 to Contact 25 and between the feed line 27 to the contact 24, which via the bearing 23 to Contact 24 takes place, causes.
