Description

Elektrischer Druckgasschalter Es ist ein Druckgasschalter mit einem düsenförmigen Kontakt bekannt, der beim Abschaltvorgang durch die Blasluft entgegen der Wirkung einer Feder von dem stiftförmigen Schaltkontakt abgehoben wird, wonach sich der stiftförmige Kontakt in die Ausschaltstellung bewegt und der düsenförmige Kontakt nach Aufhören der Deblasung durch die Feder wieder in seine Ausgangsstellung zurückbewegt wird. Die Einschaltung wird dabei allein durch Bewegen des stiftförmigen Kontaktes bewirkt.Electric pressurized gas switch It is a pressurized gas switch with a nozzle-shaped contact known, which counteracts the shutdown process by the blown air the action of a spring is lifted from the pin-shaped switching contact, after which the pin-shaped contact moves into the switch-off position and the nozzle-shaped one Contact returns to its original position after the spring has stopped deflating is moved back. It is switched on simply by moving the pen-shaped Causes contact.

Die Erfindung bezieht sich ebenfalls auf 'einen Druckgasschalter mit einem düsenförmigen Kontakt, der durch die Blasluft von dem vorzugs«-eise stiftförmigen Gegenkontakt abgehoben wird. Dabei handelt es sich darum, möglichst kurze Einschaltzeiten zu erreichen. Zu diesem Zweck wird der Düsenkontakt erfindungsgemäß nach dem Abheben vorn seinem Gegenkontakt in der Ausschaltstellung verklinkt und die Einschaltung des - Schalters durch Freigabe der Verklinkung mittels des Düsenkontaktes vorgenommen;. Der andere Kontakt braucht bei der Ausschaltung gar nicht bewegt zu -werden oder nur so weit, wie dies für die Lichtbogenlöschung erforderlich ist. Nach erfolgter Lichtbogenlöschung wird er im letzteren Fall aber wieder in seine Ausgangslage zurückgebracht, damit beim nachfolgenden Einschaltvorgang der zurückzulegende Einschaltweg genügend klein ist.The invention also relates to a gas pressure switch a nozzle-shaped contact, which is driven by the blown air from the preferably pin-shaped Counter contact is lifted. It is a question of switching on times as short as possible to reach. For this purpose, the nozzle contact is made according to the invention after it has been lifted off latched in front of its mating contact in the switch-off position and the switch-on the - switch made by releasing the latch by means of the nozzle contact ;. The other contact does not need to be moved when it is switched off or only as far as is necessary to extinguish the arc. After In the latter case, arc extinguishing is returned to its original position, so that the switch-on path to be covered is sufficient for the subsequent switch-on process is small.

Die Zeichnung veranschaulicht die Erfindung in schematischer Weise. Dabei sind nur die zur Erläuterung der Erfindung erforderlichen Teile dargestellt, während alle übrigen 'Schalterteile fortgelassen sind. In den einzelnen Figuren ist i der düsenförmige Kontakt des Schalters, der durch die in Richtung der Pfeile 2 strömende Blasluft entgegen der Wirkung der Feder 3 in die Ausschaltstellung bewegt und dort durch die Verklinkung q. festgehalten wird. Mit 5 ist der stiftförmige Gegenkontakt bezeichnet. Fig. i zeigt die Einschaltstellung. In Fig. ?- ist der Düsenkontakt i durch die Blasluft vom stiftförmigen Kontakt 5 abgehoben und in der Ausschaltlage durch die Klinke 4. festgestellt worden. Die Einschaltung ist wieder in. Fig. 3 veranschaulicht. Sie erfolgt dadurch, daß die Klinke q. in Richtung des Pfeiles 6 abgezogen wird, worauf die Feder 3 die Düse i mit großer Geschwindigkeit zu dem Stiftkontakt zurückbewegt. In Fig. q. ist der ertvähnte Fall dargestellt, bei dem auch der Stiftkontakt 5 bei der Abschaltung zurückbewegt -wird. Er wird dann nach erfolgter Lichtbogenlöschung in die in strichpunktierten Linien dargestellte Lage zurückgeführt.The drawing illustrates the invention in a schematic manner. Only the parts required to explain the invention are shown, while all other switch parts are omitted. In the individual figures, i is the nozzle-shaped contact of the switch which, by the blowing air flowing in the direction of the arrows 2, moves against the action of the spring 3 into the switched-off position and there by the latching q. is being held. The pin-shaped mating contact is denoted by 5. Fig. I shows the switch-on position. In Fig. ? - the nozzle contact i has been lifted off the pin-shaped contact 5 by the blown air and has been determined in the switched-off position by the pawl 4. The activation is illustrated again in FIG. 3. It takes place in that the pawl q. is withdrawn in the direction of arrow 6, whereupon the spring 3 moves the nozzle i back to the pin contact at high speed. In Fig. Q. the case mentioned is shown in which the pin contact 5 is also moved back when switching off. After the arc has been extinguished, it is then returned to the position shown in dash-dotted lines.
