Description
Elektrisches Schütz mit Hilfskontakten In dem Hauptpatent 457.518 ist ein elektrisches Schütz mit Hilfskontakten unter Schutz gestellt, das einen besonderen, von dem Hauptkontakthebel bewegten Hilfskontakthebel hat. Der Hilfs'kontakthebel, der unter dem Einfluß einer die Schließung der Hilfskontakte anstrebenden Feder steht, wird hierbei von dem Hauptkontakthebel so gesteuert, daß er die Hilfskontakte erst dann einschalten kann, wenn der Hauptkonta'kthebel seine Ausschaltlage ganz oder nahezu erreicht hat.Electrical contactor with auxiliary contacts In the main patent 457.518 is an electrical contactor with auxiliary contacts placed under protection, the one special auxiliary contact lever moved by the main contact lever. The auxiliary contact lever, under the influence of a spring striving to close the auxiliary contacts is here, is controlled by the main contact lever so that it has the auxiliary contacts can only switch on when the main contact lever is completely in its switch-off position or has almost reached.
Dieser Einrichtung wie überhaupt allen durch Federkraft zu schließenden Kontaktgebern haftet noch der Mangel an, daß der bewegliche Hilfskontakt bei einem mehr oder weniger heftigen Aufschlagen auf den festen Gegenkontakt zurückprallt und den geschlossenen Stromkreis nochmals oder sogar mehrmals unterbricht. Wird nun durch den Hilfskontakthebel irgendein folgendes Schütz angesteuert, so kann es vorkommen, daß die Erregung der Zugspule desselben nochmals unterbrochen wird, was besonders dann schädlich ist, wenn dieses Schütz bereits auf dem Wege des Einschaltens sich befunden hat. Abgesehen hiervon, treten an den Hilfskontakten in unerwünschter und ganz unnötiger Weise Unterbrechungsfunken - auf, welche die Kontakte rasch zerstören.This device, like all others, can be closed by spring force Contactors still adheres to the lack of that the movable auxiliary contact with a more or less violent impact bounces back on the fixed mating contact and interrupts the closed circuit again or even several times. Will now any following contactor is controlled by the auxiliary contact lever, so can it can happen that the excitation of the pull coil is interrupted again, which is particularly harmful when this contactor is already on the way of switching on has been. Apart from this, the auxiliary contacts occur in undesirable and quite unnecessarily interrupting sparks - which quickly destroy the contacts.
Um den eingangs erwähnten Mangel zu vermeiden, ist gemäß- der Erfindung der durch Federkraft zu schließende Hilfskontakthebel außer mit der im Hauptpatent angegebenen Sperrung mit einer Klinke versehen, die ihn in dem Augenblick des Aufeinanderprallens der Hilfskontakte =in der Schließlage festhält, bis die Massenschwingungen aufgehört haben. Hiernach kehrt die Klinke in ihre Anfangslage zurück, so daß sie den Hebel für den etwa folgenden Ausschaltvorgang wieder freigibt.In order to avoid the deficiency mentioned at the beginning, according to the invention the auxiliary contact lever to be closed by spring force except for the one in the main patent specified lock provided with a pawl that him at the moment of collision the auxiliary contacts = hold in the closed position until the mass oscillations cease to have. The pawl then returns to its initial position, so that the lever releases again for approximately the following switch-off process.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung gezeigt. Die Abb, r zeigt den Hauptkontakthebel c mit den geschlossenen Hauptkontakten a und b und den mittels der Klinke in der Ausschaltlage gehaltenen Hilfskontakthebel i, der unter dem Eirifluß der Federn bestrebt ist, die Hilfskontakten zu schließen. An dem Hebel! ist noch eine Klinke p gelenkig befestigt, die mit dem Nokken r und dem Sperrteil s zusammenwirkt.An exemplary embodiment of the invention is shown in the drawing. Fig, r shows the main contact lever c with the closed main contacts a and b and the auxiliary contact lever i, which is held in the open position by means of the pawl and which tries to close the auxiliary contacts under the flow of the springs. At the lever! is still a pawl p articulated, which cooperates with the cam r and the locking part s.
Die Wirkungsweise ist folgende: Wenn der Hauptkontakthebel c mittels des Gestänges e seine Kontaktea und b öffnet, stößt, sobald er die Ausschaltlage erreicht, die an seinem rückwärtigen Ende befestigte Rolle gegen die Klinke g (vgl. Abb. 2) und bringt diese außer Eingriff mit dem Hilfskontakthebeli. Dieser wird durch die Feder tt im Sinne einer Schließbewegung der Hilfskontakte k bewegt. In dem Augenblick des Aufeinanderprallens der Hilfskontakte k stößt die Klinke p schlagartig gegen den Nockenr und wird entgegen dem Uhrzeigersinne so gedreht, daß sie, wie dies in der Abb.2 gestrichelt angedeutet ist, sich an dem Sperrstücks verankert. Da die Klinke p an dem Hebel i festsitzt, wird ein Zurückprallen desselben wirksam verhindert, und die Hilfskontakte k werden so lange zwangsläufig geschlossen gehalten, bis sich die Massenschwingungen beruhigt haben. Diese Schwingungen dauern nur kurze Zeit an und unterstützen das Festhalten der Klinkep in dar Sperrstellumg. Die Klinke fällt danach wieder durch ihr Eigengewicht in die Anfangsstellung zurück, so daß sie aus dem Bereich des Sperrstückes ukommt und den Schalthebel i für die kommende Ausschaltbewegung freigibt.The mode of operation is as follows: If the main contact lever c by means of of the linkage e his contacts a and b opens, as soon as he comes across the Reached switch-off position, the role attached to its rear end against the Pawl g (see Fig. 2) and disengages it from the auxiliary contact leveri. This is activated by the spring tt in the sense of a closing movement of the auxiliary contacts k moves. At the moment when the auxiliary contacts k collide, the The latch p abruptly against the cam r and is turned counterclockwise so that that they, as indicated by dashed lines in Fig.2, are attached to the locking piece anchored. Since the pawl p is stuck on the lever i, it will rebound effectively prevented, and the auxiliary contacts k are forcibly closed for so long held until the mass oscillations have calmed down. These vibrations last only for a short time and support the holding of the Klinkep in the Sperrstellumg. The pawl then falls back into its starting position due to its own weight, so that it comes out of the area of the locking piece and the shift lever i for the releases the upcoming switch-off movement.
Der Erfindungsgedanke ist auf die an Hand des Beispiels erläuterte Ausführungsform nicht beschränkt; man kann vielmehr den gleichen Zweck auch mit einer ähnlichen Anordnung erreichen.The idea of the invention is explained on the basis of the example Embodiment not limited; you can rather use the same purpose as well achieve a similar arrangement.
