Description

Elektrischer Stromunterbrecher, insbesondere Schalter mit Lich.tbogenlöschung durch ein strömendes Druckmittel Die Erfindung bezieht sich auf einen elektrischen Stromunterbrecher, insbesondere Schalter mit Lichtbogenlöschung durch ein strömendes Druckmittel, bei «dem zur Lichtbogenlöschung der durch den Abschaltlichtbogen selbst in dem ihn umgebenden, vorzugsweise gasförmigen Medium hervorgerufene Druckstoß bzw. die hervorgerufene Druckwelle in der Weise ausgenutzt wird, daß durch die vorzugsweise rohrförmige Ausbildung der die Schaltkontakte enthaltenden Schaltkammer der vom Lichtbogen erzeugte Druckstoß bzw. die Druckwelle derart gelenkt wird, daß sie wieder auf den Lichtbogen auftrifft, nach Patent 730 505. Electrical circuit breaker, in particular switch with arc extinguishing by a flowing pressure medium The invention relates to an electrical circuit breaker, in particular switch with arc extinguishing by a flowing pressure medium, in which the arc extinguishing is caused by the cut-off arc itself in the surrounding, preferably gaseous medium Pressure surge or the generated pressure wave is exploited in such a way that, through the preferably tubular design of the switching chamber containing the switching contacts, the pressure surge or pressure wave generated by the arc is directed in such a way that it strikes the arc again, according to patent 730 505.

Die Erfindung befaßt sich insbesondere mit der Lichtbogenlöschung kleiner Ströme mit einem solchen Schalter.The invention is particularly concerned with arc extinction small currents with such a switch.

Hierbei läßt sich dieWirkung des Schalters erheblich steigern, wenn man erfindungsgemäß im Hinblick auf die Lichtbogenlöschung kleiner Ströme ein verhältnismäßig langes enges Rohr als Schaltkammer verwendet oder wenn man an ein kürzeres Rohr eine Zusatzkammer anschließt.The effect of the switch can be increased considerably if one according to the invention with regard to the arc extinction of small currents a relatively long narrow pipe used as a switching chamber or when connected to a shorter pipe an additional chamber is connected.

Die Zusatzkammer kann in einfacher Weise durch eine Erweiterung des abgeschlossenen Rohrendes hergestellt werden.The additional chamber can be easily expanded by expanding the completed pipe end can be produced.

Die Zeichnung zeigt zwei beispielsweise Ausführungen der Erfindung.The drawing shows two exemplary embodiments of the invention.

Abb. i zeigt die Verwendung eines langen Rohres als Schaltkammer.Fig. I shows the use of a long pipe as a switching chamber.

Abb. z zeigt die Verwendung eines kürzeren Rohres mit einer sich daran anschließenden Zusatzkammer. In jeder Abbildung bedeutet i das Löschrohr, in dem die Schaltkontakte a und 3, die im- gezeichneten Beispiel als Schubkontakte ausgebildet sind, untergebracht sind. In Abb. a ist .I die sich an das Rohr i anschließende Zusatzkammer.Fig. Z shows the use of a shorter pipe with a stick attached to it subsequent additional chamber. In each figure i means the extinguisher pipe in which the switching contacts a and 3, the example shown in the drawing, are designed as push contacts are housed. In Fig. A, .I is the one following pipe i Additional chamber.

Elektrischer Stromunterbrecher nach Anspruch i, dadurch gekennzeichnet, daß die Zusatzkammer in einer Erweiterung des abgeschlossenen Rohrendes bestellt.PATENT CLAIMS: i. Electrical circuit breaker, in particular switch with arc extinguishing by a flowing pressure medium, in which for arc extinguishing the pressure surge or the pressure wave caused by the cut-off arc itself in the surrounding, preferably gaseous medium, is used in such a way that the preferably rolling formation of the Schaltlcontaltte containing switching chamber the pressure surge or the pressure wave generated by the arc is directed in such a way that it strikes the arc again, according to patent 730 505, characterized in that a relatively long, narrow tube is used as the switching chamber with regard to the extinction of small currents or that a shorter tube is provided with an additional chamber. Electrical circuit breaker according to Claim i, characterized in that the additional chamber is arranged in an extension of the closed pipe end.
