Description
Die Anordnung unterscheidet sich, im wesentlichen gegenüber der bisherigen Bauweise dadurch, daß die pro Pol in Serie angeordneten Kontaktstellen teilweise mit an sich bekannten Löschkammern versehen sind.The arrangement differs, essentially compared to the previous design in that the per pole arranged in series Contact points are partially provided with extinguishing chambers known per se.
Bei großen Schaltern werden die beim Ausschalten zu beschleunigenden Massen so groß, daß eine zu träge, mechanische Ausschaltbewegung resultiert und damit der Funke ίο langer stehenbleibt. Um diese schädliche Eigenschaft zu vermeiden, hat man derartige Schalter mit nachschnellenden Kontakten versehen oder mit Vielfachfunkenstrecken bis zu io in Serie angeordnet. Beides sind unerwünschte Komplikationen.In the case of large switches, the masses to be accelerated when switching off are like this great that a too sluggish, mechanical switch-off movement results and with it the spark ίο stops longer. To this harmful To avoid this property, such switches have been provided with snap-in contacts or arranged in series with multiple spark gaps up to io. Both are undesirable Complications.
Um dies zu vermeiden, ist nach vorliegender Ausführung die anerkannt gute Wirkung der Löschkammer in Serienschaltung angeordnet, so daß aus der Kombination einer Serienschaltung mehrerer Kontakte und der Druck- und Spülwirkung der Löschkammer eine kürzeste Ausschaltedauer des entstehenden Ausschaltfunkens gegeben ist.In order to avoid this, according to the present version, the recognized good effect is the arcing chamber arranged in series, so that from the combination of a series circuit of several contacts and the Pressure and flushing effect of the extinguishing chamber result in the shortest switch-off time Switch-off spark is given.
In der Zeichnung ist eine Sechsfachunterbrechung dargestellt, und zwar bedeutet:A six-fold interruption is shown in the drawing, which means:
α Durchführungsisolatoren, b Lösehkammern, c eine an der Haupttraverse d isoliert befestigte und damit bewegte Kontaktbrücke mit dem verlängerten Kontakte. / ist die Gegenkontaktbrücke, die im Falle der Anwen- 3<* dung eines Anlaßwiderstandes g durch denselben mit dem Kontaktbolzen der Durchführung α verbunden ist. α bushing insulators, b release chambers, c a contact bridge with the extended contacts, which is attached in an insulated manner to the main traverse d and thus moved. / Is the counter contact bridge, the manure in the case of application 3 <* a starter resistor g by the same with the contact pin of the bushing is connected α.
Bei der Anwendung eines Vorschaltwiderstandes g ist in bekannter Weise die Anordnung so getroffen, daß die Kontaktstellen /, e zuletzt getrennt werden.When using a series resistor g , the arrangement is made in a known manner so that the contact points /, e are separated last.
