  Ölschalter mit Haupt-und Nebenkontakten. 



   Es ist bekannt, die Kontakte von   Ölschaltern   im Innern von sogenannten Löschkammern anzuordnen, die den durch die   Otvergasung   entstehenden Druck zur   Löschung des Lichtbogens   ausnutzen. Bei Ölschaltern, die zur   Unterbrechung grosser Leistungen   dienen, würden diese 
 EMI1.1 
 führen. 



   Gemäss der Erfindung werden in an sich bekannter Weise ausser den für die Führung des   Gesamtstromes bemessenen Hauptkontakten   des Schalters Xebenkontakte verwendet. Die Erfindung besteht nun darin, dass nur diese   Xebenkontakte'm   Innern von Löschkammern angeordnet sind. Die Öffnung der Hauptkontakte erfolgt im freien   Ölraum.   Die Unterbrechung des Stromes dagegen erfolgt an den parallel zu den Hauptkontakten angeordneten Nebenkontakten, die sich in bekannter Weise beim Ausschalten erst nach den IIauptkontakten öffnen. 



  Die Löschkammern erhalten dadurch, dass sie nur   Nehenkontakte enthalten, sehr   kleine Abmessungen ; sie sind daher bequem an die Tr. gkonstruktion für die Hauptkontakte anzuhauen. 



   Die Zeichnung zeigt ein Ausführungsbeispiel. Es bezeichnet 1 den Ölkasten, 2 dessen Deckel, 3 die Druchführungsisolatoren, 4 die Träger der   Hauptkontakte, J die Hauptkontakte,   6 die die beweglichen Kontakte tragende Traverse. 7 den festen Nehenkontakt, 8 den beweglichen Nehenkontakt. 9 die die beiden letzteren   umschliessende     Löschkammer.

  Oil switch with main and secondary contacts.



   It is known to arrange the contacts of oil switches in the interior of so-called arcing chambers which use the pressure generated by the gasification to extinguish the arc. In the case of oil switches that are used to interrupt large outputs, these would
 EMI1.1
 to lead.



   According to the invention, secondary contacts are used in a manner known per se in addition to the main contacts of the switch, which are dimensioned for carrying the total current. The invention consists in that only these Xebenkontakte are arranged inside the arcing chambers. The main contacts are opened in the free oil space. The interruption of the current, on the other hand, takes place at the secondary contacts which are arranged parallel to the main contacts and which, in a known manner, only open after the main contacts when switched off.



  The arcing chambers have very small dimensions because they contain only close contacts; they are therefore convenient to the door. g construction for the main contacts.



   The drawing shows an embodiment. It denotes 1 the oil box, 2 its cover, 3 the bushing insulators, 4 the carriers of the main contacts, J the main contacts, 6 the traverse carrying the movable contacts. 7 the fixed close contact, 8 the movable close contact. 9 the extinguishing chamber enclosing the latter two.
