Description
Bei elektrischen Überstromschaltern, die beim Ansprechen des Schalters mit geringer Kraft ausgelöst werden, kommen häufig Kraftspeicher in Anwendung, die mit größerer Kraft und Geschwindigkeit die Sperrung des Schalters herausschlagen und den Schalter in die Ausschaltstellung bringen. Die Ausschaltgeschwindigkeit solcher Schalter ist in allen Fällen gleich, schnell. Es ist aber wichtig, daß die Schnelligkeit der Ausschaltung mit der Höhe der abzuschaltenden Stromstärke wächst, da andernfalls vorgeschaltete Sicherungen eher durchbrennen, wie die Unterbrechung des Stromkreises durch den Überstromschalter erfolgt.In the case of electrical overcurrent switches, when the switch responds with less Force are triggered, energy storage devices are often used, those with larger ones Force and speed knock out the lock on the switch and hit the switch bring it to the switch-off position. The opening speed of such switches is in same in all cases, quickly. But it is important that the speed of the switch-off grows with the level of the current to be switched off, otherwise it is connected upstream Fuses are more likely to blow like the circuit breaker is done by the overcurrent switch.
Die Erfindung betrifft solche elektromagnetische Überstromschalter mit einer den Schalter in der Einschaltstellung haltenden Sperrvorrichtung, die durch einen vom Auslösemagnetanker gesteuerten Kraftspeicher ausgelöst werden, bei denen erfindungsgemäßt die Bewegung des Stößers des Kraftspeichers durch die Kraft des»Auslösemagnieten beschleunigt wird. Die Abschaltgeschwindigkeit ist daher um so schneller, je höher die abzuschaltende Stromstärke ist.The invention relates to such electromagnetic overcurrent switches with a switch in the switched-on position locking device, which is controlled by one of the tripping magnet armature controlled energy storage are triggered, in which the invention Movement of the lift mechanism pusher accelerated by the force of the »release magnet will. The shutdown speed is therefore faster, the higher the shutdown rate Amperage is.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung an einem Kniehebelselbstschalter. The drawing shows an embodiment of the invention on a toggle self-switch.
Der Kniehebel a, b, c, dessen Lasche c mit einem Gelenkzapfen in der Schienen? gleitet, ist in die Strecklage gebracht und hält die nicht gezeichneten Kontakte des Schalters geschlossen. Der Anker & des AuS-lösemagnets tn ist bei g gelagert und an seinem Hebel h mit einer Rückzugsfeder/ versehen. In eine Auslassung/ greift die Sperrnase« des aus dem bei I gelagerten Stößers s und der Feder k bestehenden Kraftspeichers und hält ihn gespannt. Bei Überstrom wird der Ankere angezogen und gibt den Stößers frei, so daß er gegen den Kniehebel b, c schlägt und diesen zum Einknicken bringt, wodurch die Ausschaltung erfolgt. The toggle lever a, b, c, whose bracket c with a pivot pin in the rails? slides, is brought into the extended position and keeps the not shown contacts of the switch closed. The armature & of the releasing magnet tn is mounted at g and is provided with a return spring / on its lever h. The locking lug «of the force storage mechanism, which consists of the tappet s mounted at I and the spring k , engages in an omission and keeps it taut. In the event of an overcurrent, the armature is attracted and releases the pusher, so that it strikes against the toggle lever b, c and causes it to buckle, which means that it is switched off.
Zwischen dem Hebel h des Ankers e und dem Stößers ist so viel freies Spiel, daß der Anber ungehindert die Nase« freigeben kann. Ist nun die Bewegung des Ankers infolge eines honen Stromstoßes oder Kurzschlusses schneller als diejenige des Stößers s, so schlägt der Hebel k gegen den Stößer und erhöht und kräftigt dessen Geschwindigkeit.There is so much free play between the lever h of the armature e and the pusher that the anchor can unhindered release the nose. If the armature's movement is faster than that of the pusher s as a result of a harsh electric shock or short circuit, then the lever k strikes against the pusher and increases and strengthens its speed.
Bei der Verwendung einer thermischen Auslösung wirkt diese auf den Anber e in gleicher Weise wie der Magnet tn. If a thermal release is used, this acts on the indicator e in the same way as the magnet tn.
