Description

Elektrischer Gasschalter Die Erfindung betrifft einen Druckgasschalter der Schubschalterbauart, welcher sich das zur Lichtbogenlöschung erforderliche Löschgas durch Einwirkung des Ausschaltlichtbogens auf gasabgebende Kammerwandungen selbst erzeugt. Die Spitze des bewegten Schaltgliedes (Rohr, Stift o. dgl.) durchläuft beim Ausschalten nach der Kontakttrennung eine dem festen, Kontakt vorgelagerte Isolierhülse aus gasabgebendem Material. Für größere Leistungen ist diese Hülse izi bekannter Weise noch mit einer hesonderen Kammer aus Isolierstoff umgeben, in welche ein großer Teil der Schaltgase eintritt, bevor das bewegte Schaltglied das Isolierrohr ganz verlassen hat.Electric gas switch The invention relates to a compressed gas switch the push-button type, which has the extinguishing gas required to extinguish the arc by the action of the switch-off arc on the gas-emitting chamber walls themselves generated. The tip of the moving switching element (tube, pin or the like) passes through when switching off after the contact has been separated, an upstream of the fixed contact Insulating sleeve made of gas-emitting material. This sleeve is for greater performance izi known way still surrounded with a special chamber made of insulating material, in which a large part of the switching gases enters before the moving switching element the Has left the insulating tube completely.

Wie bei anderen Leistungsschaltern, so ist es auch bei einem solchen Gasschalter aus wirtschaftlichen Gründen erwünscht, für hohe Stromstärken nicht den gesamten Betriebsstrom über den Leistungskontakt zu leiten, sondern einen erheblichen. Teil über einen Parallelweg zu führen, dessen Kontakt früher trennt und später schließt als der Hauptkontakt. Einer solchen Anordnung stand bisher der Umfang der das eigentliche Löschrohr umgebenden Bl,askammer hindernd im Wege.As with other circuit breakers, it is the same with one Gas switch desirable for economic reasons, not for high currents to conduct the entire operating current via the power contact, but a considerable one. To lead part of a parallel path, the contact of which separates earlier and closes later as the main contact. Such an arrangement was previously the scope of the actual Extinguishing pipe surrounding fire chamber obstructing the way.

Nach der Erfindung wird diese Schwierigkeit dadurch beseitigt, daß das Parallelschaltstück durch die Blaskammer selbst hindurchgeführt wird, und zwar vom Kammerinnern isoliert, um Rückzündungen durch die Schaltgase zu vermeiden.According to the invention, this problem is eliminated in that the parallel switching piece is passed through the blow chamber itself, namely insulated from the inside of the chamber in order to avoid re-ignition by the switching gases.

Eine beispielsweise Ausführung ist auf der Zeichnung veranschaulicht. Außer den Leistungssch.altkontakten, bestehend ,aus dem bewegten Schaltstücka und dem festen Kontakt b, welcher sich hinter dem Löschrohr c befindet, sind noch Parallelkontakte vorgesehen, und zwar das Schaltstückd und der feste Kontakt e. Dabei ist erfindungsgemäß die Anordnung so getroffen, daß die Durchtrittsstelle des Parallelkontaktes in der Blaskammer f durch das Isolierrohr g gegen das Innere der Kammer f mechanisch und elektrisch abgeschlossen ist. Die Schaltstücke a und d werden von der Schaltwelle h aus über die Schaltschwinge i und die Zuglaschen hl und h_, bewegt.An example implementation is illustrated in the drawing. In addition to the power switching contacts, consisting of the moving contact piece a and the fixed contact b, which is located behind the extinguishing pipe c, parallel contacts are also provided, namely the contact piece d and the fixed contact e. According to the invention, the arrangement is such that the passage point of the parallel contact in the blow chamber f is mechanically and electrically closed off by the insulating tube g from the interior of the chamber f. The switching pieces a and d are moved from the switching shaft h via the switching rocker i and the pull straps hl and h_.

Natürlich können auch mehr als ein. Parallelkontakt durch die Blaskammer hindurchgeführt werden.Of course you can do more than one. Parallel contact through the blow chamber be passed through.
