Description
Um bei der Abschaltung von Schaltern großer Leistung den auftretenden Lichtbogen schnell zum Erlöschen zu bringen, war bisher die Anordnung so getroffen, daß vor dem Abschalten, zuerst eine Blasspule eingeschaltet und dann erst der Schalter abgeschaltet wurde. Es waren also zwei Betätigungsvorgänge notwendig, die die Geschwindigkeit des Abschaltens beeinträchtigten. Nach vorliegender Erfindung wird dieser Mangel dadurch beseitigt, daß die Stromunterbrechung durch zwei oder mehrere in Reihe geschaltete Unterbrechungsstellen erfolgt, die gleichzeitig betätigt werden. Die Blasspule überbrückt eine der Unterbrechungsstellen und wird so nur im Augenblick des Abschaltens wirksam. Sie kann entweder nur auf die ganz offenen Unterbrechungsstellen oder aber auch auf sämtliche einwirken. Da nur ein Schaltvorgang aus-In order to avoid the arc that occurs when switching off high-performance switches to extinguish quickly, the arrangement was made so that before Switch off, first switch on a blower coil and only then switch off the switch became. So two operations were necessary to reduce the speed of the Shutdown impaired. According to the present invention, this deficiency is eliminated eliminates that the current interruption by two or more interruption points connected in series which are actuated at the same time. The blow-off coil bridges one of the interruption points and is only so effective at the moment of switch-off. You can either only apply to the completely open interruption points or also affect all of them. Since only one switching operation is
ao zuführen ist, wird eine große Geschwindigkeit des Abschaltens erreicht.ao is to be fed, a high shutdown speed is achieved.
Eine der möglichen Ausführungsformen zeigt die Abbildung, und zwar für zwei Unterbrechungsstellen, α ist die Stromzuführung, b die Stromabführung, c ist der Schalter, der die beiden Unterbrechungsstellen gleichzeitig betätigt. Die eine Unterbrechungsstelle ist durch die Blasspule d überbrückt, die im Augenblick des Abschaltens in Wirksamkeit tritt und das Feuer an der offenen Unter- brechungsstelle oder evtl. an beiden durch magnetische Blasung schnell zum Erlöschen bringt.One of the possible embodiments is shown in the figure, specifically for two interruption points, α is the power supply, b is the current discharge, c is the switch that actuates the two interruption points simultaneously. One interruption point is bridged by the blower coil d, which comes into effect at the moment it is switched off and quickly extinguishes the fire at the open interruption point or possibly both by means of magnetic blowing.
