Description
Die vorliegende Neuerung ist für kleine mehrpolige Überstromschalter bestimmt, die durch einen Kniehebel in der eingeschalteten Lage gehalten werden, und bei denen bei Ansprechen in einer Phase durch· das Herausschlagen des Kniehebels dieser Phase die Auslösung aller Phasen vor sich gehen soll. Um dieses in einfachster Form zu erreichen, ist die Einrichtung getroffen worden, daß beim Auslösen eines Poles ein Kraftmoment frei wird, das den Einschaltmechanismus in die Ausschaltstellung zurückbringt und damit das Abschalten aller Pole bewirkt. Wird z.B. als freiwerdendes Kraftmoment bei einem dreipoligen Schalter eine gespannte Feder verwendet, so muß diese so abgestimmt sein, daß bei der Einschaltung die Wirkung der drei Kniehebel der drei einzelnen Pole der Federwirkung mindestens das Gegengewicht bietet. Wird dagegen durch Ansprechen eines Magneten in so einem Pol ein Kniehebel gelöst, so erhält die als Kraftspeicher dienende gespannte Feder das Übergewicht über die beiden andern Kniehebel und bringt den Schalter in die Ausschaltlage. The present innovation is intended for small multi-pole overcurrent switches that be held in the switched-on position by a toggle lever, and when responding in one phase by · knocking out the knee lever in this phase the release all phases should go on. In order to achieve this in the simplest form, the Arrangement has been made that a moment of force is released when a pole is triggered, which brings the switch-on mechanism back into the switch-off position and thus the switch-off of all poles. If, for example, a tensioned spring is used as the released moment of force in a three-pole switch, this must be coordinated in such a way that the three toggle levers act when switched on of the three individual poles of the spring action provides at least the counterweight. Will against it by activating a magnet in such a pole, a toggle lever is released, the The tensioned spring serving as an energy store removes the excess weight over the other two toggle levers and brings the switch to the switch-off position.
Eine solche Anordnung ist in der Zeichnung dargestellt. Abb. ι zeigt den Schalter in der Einschaltlage, Abb. 2 in der Ausschaltlage, Abb. 3 ist ein Grundriß. Es bezeichnet α den Griff des Schalters, der durch den Kniehebel b den Kontaktteil c gegen den festen Kontakt d drückt, e ist die Ausschaltfeder, / sind Aus-Such an arrangement is shown in the drawing. Fig. Ι shows the switch in the switched-on position, Fig. 2 in the switched-off position, Fig. 3 is a plan. It refers to α the handle of the switch b by the toggle lever the contact portion c against the fixed contact d suppressed, e is the opening spring, is / are off

lösemagnete. In der eingeschalteten Lage sind die drei Kniehebel h (s. Abb. i) durch das Heraufbewegen des Handgriffes a> gespannt, und die Kontaktteile c machen mit d Kontakt. Die Ausschaltfeder e ist gespannt, da aber der Kniehebeldruck der drei Kniehebel überwiegt, kann sie den Schalter nicht in die Ausschaltlage bringen. Tritt dagegen in einem der Pole Überstrom ein und spricht dessen Magnet f an, so daß einer der Kniehebel herausgedrückt wird, dann erhält die Feder / das Übergewicht und bringt den Schalter in die Ausschaltlage (s. Abb. z). . release magnets. In the switched-on position, the three toggle levers h (see Fig. I) are tensioned by moving the handle a> upwards, and the contact parts c make contact with d. The switch-off spring e is tensioned, but since the knee lever pressure of the three toggle levers predominates, it cannot bring the switch into the switch-off position. If, on the other hand, an overcurrent occurs in one of the poles and its magnet f responds, so that one of the toggle levers is pushed out, the spring / becomes overweight and brings the switch to the switch-off position (see Fig. Z). .
