Description

Stromunterbrecher, insbesondere Schalter mit Lichtbogenlöschung durch ein Druckmittel Die Erfindung bezieht sich auf einen elektrischen Stromunterbrecher, insbesondere Schalter mit Lichtbogenlöschung durch ein Druckmittel, bei dem zur Lichtbogenlöschung der dui#ch den Abschaltldchrbog,en selbst in dem ihn umgebenden Medium hervorgerufene Druckstoß bzw. die hervorgerufene Druckwelle in der Weise ausgenutzt wird, daß durch die Ausbildung der die Schaltkontakte enthaltenden Schaltkammer der vom Lichtbogen erzeugte Druckstoß bzw. die Druckwelle derart gelenkt wird, däß sie wieder auf den Lichtbogen auftrifft, und bei dem der Schaltkammer von außen zusätzlich Druckgas für die Lichtbogenlöschung zugeführt wird, nach Patent 730 5 0 5.Circuit breaker, in particular switch with arc extinguishing by a pressure medium The invention relates to an electrical circuit breaker, in particular switch with arc extinction by a pressure medium, in which, to extinguish the arc, the pressure surge or the pressure surge caused by itself in the medium surrounding it Pressure wave is exploited in such a way that, through the formation of the switching chamber containing the switching contacts, the pressure surge generated by the arc or the pressure wave is directed in such a way that it strikes the arc again, and the switching chamber is additionally supplied with compressed gas from the outside to extinguish the arc is, according to patent 730 5 0 5.

Die Erfindung befaßt sich mit der Aufgabe, die zusätzliche Lichtbogenbeblasung so zu gestalten, dar) sie den Löschvorgang durch die selbsterzeugte Druckwelle nicht stört, sondern voll unterstützt.The invention is concerned with the task of the additional arc blowing in such a way that the self-generated pressure wave does not extinguish the extinguishing process disturbs, but fully supported.

Dies wird erfindungsgemäß durch eine solche Steuerung des Ventils für die Zuführung der Zusatzluft erreicht, daß sich der Druckstoß bzw. die Druckwelle der Zusatzbeblasung dem reflektierten Druckstoß bzw. der reflektierten Druckwelle derart überlagert, dar) sich die Löschwirkungen addieren.According to the invention, this is achieved by controlling the valve in this way for the supply of the additional air achieved that the pressure surge or the pressure wave the additional blowing the reflected pressure surge or the reflected pressure wave superimposed in this way, the extinguishing effects add up.

Die Zeichnung zeigt schematisch e!in Ausführungsbeispiel eines solchen Schalters, bei dem in :dem Rohr i die Schaltkontakte 2 und 3 angeordnet sind, zwischen die sich beim Abschaltvorgang die Isolierplatte 4 schiebt. Das Ventil 7 dient zur Steuerung der zusätzlichen Blasluft, die durch das Rohr 6 der Schaltkammer zuströmt. Die Stange 8 führt zu einer geeigneten, hier nicht gezeichneten Steuereinrichtung.The drawing shows schematically an embodiment of such Switch, in which in: the tube i the switching contacts 2 and 3 are arranged between which pushes the insulating plate 4 during the shutdown process. The valve 7 is used to Control of the additional blown air that flows through the pipe 6 of the switching chamber. The rod 8 leads to a suitable control device, not shown here.
