bei Überlastung.in case of overload.
Zusatz zum Patente 186592 vom 4. August 1906.Addendum to patent 186592 from August 4, 1906.
Patentiert im Deutschen Reiche vom 29. Juni 1907 ab. Längste Dauer: 3. August 1921.Patented in the German Empire on June 29, 1907. Longest duration: August 3, 1921.
Bei dem nach Patent 186592 ausgeführten Schalter zeigt es sich, daß derselbe, wenn er bei Überlastung in Wirksamkeit getreten ist, auch noch bei Verminderung der Strombelastung in Bewegung bleibt, da zur Erhaltung der Bewegung eine geringere Kraft nötig ist als zur Einleitung derselben.In the switch made according to patent 186592, it turns out that the same when he has come into effect in the event of overload, even if the current load is reduced remains in motion, since less force is required to maintain the motion than to initiate it.
Diesen Übelstand beseitigt der Gegenstand vorliegender Erfindung. Er besteht aus einem einerseits durch eine Abreißfeder, anderseits durch die Polschuhe des auf den schwingenden Anker einwirkenden Elektromagneten beeinflußten Hebel, welcher bei normaler, auf den Elektromagneten' wirkenden Stromstärke infolge der Wirkung der_ Abreißfeder den Anker arretiert, bei zu großer Stromstärke jedoch entgegen der Wirkung der Abreißfeder von dem Elektromagneten angezogen wird und dadurch den Anker freigibt. Ein Schwingen des Ankers kann daher nur während der Zeit der Überlastung stattfinden.The subject matter of the present invention eliminates this drawback. It consists of one on the one hand by a breakaway spring, on the other hand by the pole pieces of the oscillating Armature acting electromagnets influenced lever, which at normal, on the electromagnet 'acting amperage due to the action of the_ tear-off spring Armature locks, but if the current is too high, it goes against the action of the breakaway spring is attracted by the electromagnet and thereby releases the armature. A swing of the anchor can therefore only during the time of overload take place.
Beiliegende Zeichnung stellt eine beispielsweise Ausführungsform des Erfindungsgedankens dar. Der mit einem Eisenstück a versehene, als Unruhe ausgebildete Anker b wird durch einen Arretierhebel c bei normaler, auf den Elektromagneten d wirkenden Stromstärke in der gezeichneten Lage festgehalten, da die Wicklung des Elektromagneten d derart berechnet ist, daß bereits bei einer geringeren als der.normalen Stromstärke die Kraft des Elektromagneten d stark genug ist, um die der Feder e zu überwinden. Der Arretierhebel selbst wird durch eine Feder / in der gezeichneten Lage gehalten und besitzt an seinem dem Elektromagneten d gegenüberliegenden Ende g ein Eisenstück. Letzteres wird bei Überschreitung der normalen Stromstärke vom Magneten d entgegen der Federwirkung / angezogen, wodurch der Arretierhebel c den Anker b freigibt, so daß dieser nunmehr unter dem Einflüsse des Elektromagneten d frei schwingen und die beabsichtigten Stromkreisunterbrechungen hervorrufen kann. Sobald die normale Stromstärke wieder eintritt, wird der Arretierhebel c durch die Feder / wieder in die· gezeichnete Lage zurückgezogen, wodurch der Anker b sofort festgelegt wird.The accompanying drawing shows an example embodiment of the inventive concept. The armature b , provided with an iron piece a and designed as a balance, is held in the position shown by a locking lever c at normal current strength acting on the electromagnet d , since the winding of the electromagnet d is calculated in this way is that the force of the electromagnet d is strong enough to overcome that of the spring e even at a lower than the normal current strength. The locking lever itself is held in the position shown by a spring / and has a piece of iron at its end g opposite the electromagnet d. The latter is attracted by the magnet d against the spring action / when the normal current strength is exceeded , whereby the locking lever c releases the armature b so that it can now swing freely under the influence of the electromagnet d and cause the intended circuit interruptions. As soon as the normal current strength occurs again, the locking lever c is pulled back into the position shown by the spring /, whereby the armature b is immediately fixed.
Die Spannkraft der Feder/kann verschieden einstellbar sein, so daß die zur Ingangsetzung des Schalters nötige Stromstärke je nach Bedarf in gewissen Grenzen eingestellt werden kann.The tensioning force of the spring / can be set in different ways, so that the start-up of the switch required amperage can be set within certain limits as required.
