Description

Es sind Flüssigkeitsschalter bekannt, bei denen der Einfachheit der Anordnung halber weder besondere Abreißkontakte noch Löschkammern zur Verwendung gelangen. Gelangen bei solchen Schaltern den Stiftkontakt ringförmig· umgebende Kontaktfinger zur Anwendung, so sind Maßnahmen erforderlich, um deren Befestigungsteile vor den schädlichen-Einwirkungen des Lichtbogens zu schützen. to Fenner ist es notwendig, die Kontaktfinger so anzuordnen, daß die Gefahr des Stauchens bei der Einschaltbewegung nach Möglichkeit vermieden wird.There are liquid switches are known in which the simplicity of the arrangement neither special tear-off contacts nor arcing chambers are used. Reach contact fingers surrounding the pin contact in a ring shape for use in such switches, Measures are required to protect their fasteners from the harmful effects to protect against the arc. to fenner it is necessary to use the contact fingers to be arranged so that there is a risk of upsetting during the switch-on movement if possible is avoided.

Diese Anforderungen werden durch den Gegenstand der Erfindung, einen Flüssigkeitsschalter ohne Löschkammer, bei welchem in an sich bekannter Weise die Stiftkontakte feststehend und die die Stiftkontakte ringförmig umgreifenden, federnden Kontaktfinger an der beweglichen Traverse angebracht sind, in folgender Weise erfüllt. Erfindungsgemäß erstrecken sich die Kontaktfinger zwecks Vermeidung der Gefahr des Stauchens bei der Einschaltbewegung in der Ausschaltrichtung,· sie sind in der Form etwa eines Trichters angeordnet, an dessen größerer Öffnung die Befestigungsteile und an dessen kleinerer Öffnung die Kontakte der federnden Kontakt-Singer ringförmig um die geometrische Achse des Stiftkontaktes herumliegen, der mit seiner Spitze in dieselbe Richtung weist wie die Spitze des Trichters. Die federnden Kontaktfingier werden also beim Auftoeffen des Stiftkontaktes stets nach außen nachgeben, während ein Stauchen oder Verbiegen derselben niemals eintreten kann. Ferner sind die Befestigungsteile der Kontaktfinger, die gerade bei einer solchen Anordnung den Einflüssen des Lichtbogens besonders stark ausgesetzt sind, zum Schutz gegen diese innerhalb eines ringförmigen, in der Ausschaltrichtung bzw. in der Richtung des Stiftkontaktes offenen Raumes angeordnet, der durch Umbördelung des dem festen Kontaktstift zugekehrten Endes eines feuerfesten, mit der Traverse verbundenen, der Form des festen Kontaktstiftes entsprechenden Isolierrohres gebildet ist. Mit Hilfe .einer derartigen feuerfesten Isoliertülle ist es möglich, die Befestigungsteile der Kontaktfinger der Einwirkung des 5" Lichtbogens* zu entziehen. Zugleich wird beim Aussclialten gegen den Lichtbogen durch das Isolierrolir hindurch eine Flüssigkeitsströmung getrieben, wodurch der Löschvorgang in bekannter Weise begünstigt wird.These requirements are met by the subject matter of the invention, a liquid switch without quenching chamber, in which the pin contacts are fixed in a manner known per se and the pin contacts are ring-shaped encompassing, resilient contact fingers are attached to the movable crossbeam, met in the following way. According to the invention, the contact fingers extend for the purpose of avoidance the risk of compression during the switch-on movement in the switch-off direction, they are arranged in the form of a funnel, for example, at its larger opening the fastening parts and at its smaller opening the contacts of the resilient contact singers ring around the geometric axis of the pin contact with its tip pointing in the same direction as the Top of the funnel. The resilient contact fingers are so when the pin contact is opened always yield to the outside, while compression or bending of the same can never occur. Furthermore, the fasteners the contact fingers, which are particularly exposed to the effects of the arc in such an arrangement are to protect against these within a ring-shaped, in the disconnection direction or arranged in the direction of the pin contact open space created by flanging of the end of a fireproof end facing the fixed contact pin with the cross member connected, the shape of the fixed contact pin corresponding insulating tube formed is. With the help of such a fire-proof insulating grommet, it is possible to fix the fastening parts remove the contact finger from the action of the 5 "arc * A flow of liquid through the insulating roller is released against the arc driven, whereby the deletion process is favored in a known manner.

Die Abbildungen zeigen eine Ausführungsform in zwei Ansichten. An der Durchführung α ist der feste Kontaktstift δ angebracht. An der Traverse c sind innerhalb der ringförmigen Isoliertülle^ die federnden Kontakte e befestigt. Beim Ausschalten werden die Befestigungsteile der Kontakte e durch die Tülle d vollständig geschützt, wobei durch die rohrartige Ausbildung der Traverse c sai der die Kontakte tragenden Stelle die Flüssigkeit von unten zuströmen und zugleich eine raschere Lichtbogenlöschung eintreten kann.The figures show an embodiment in two views. The fixed contact pin δ is attached to the bushing α. On the cross member c , the resilient contacts e are attached within the annular insulating sleeve ^. When switching off, the fastening parts of the contacts e are completely protected by the grommet d , whereby the tubular design of the cross member c sai of the point carrying the contacts allows the liquid to flow from below and at the same time a more rapid arc extinction can occur.
