Description
Einrichtung zum Betätigen von Selbstschaltern Die Erfindung bezieht sich auf eine Einrichtung zum Betätigen von Selbstschaltern, bei der das Magnetsystem mit zwei Kraftlinienwegen versehen ist. Die Spannungswicklung hält bei normalem Strom den Anker entgegen dem Zug einer Feder in der einen Endlage, wodurch der Selbstschalter geschlossen gehalten wird. Bei Überstrom überwiegt die Zugkraft der Stromwicklung, und der magnetische Fluß der Spannungswicklung wird in den andern Kraftlinienweg gedrängt, so daß der Schalter infolge der Summenwirkung von Strom, Spannung und Federkraft in die Offenlage umgelegt wird. .Device for actuating automatic switches The invention relates on a device for actuating automatic switches, in which the magnet system is provided with two lines of force. The voltage winding holds at normal Current the armature against the train of a spring in one end position, whereby the self-switch is kept closed. In the event of an overcurrent, the tensile force of the current winding predominates, and the magnetic flux of the tension winding is in the other line of force path pushed so that the switch as a result of the cumulative effect of current, voltage and Spring force is shifted into the open position. .
Gegenstand der Erfindung ist eine Ausführungsform einer solchen Einrichtung. Das Wesen der Erfindung besteht darin, daß die beiden Kraftlinienwege in einem [J-förniigen Magnetsystem erzeugt werden, das mit je zwei von den Schenkeln nach innen ragenden und einander gegenüberstehenden Polpaaren und mit einem j-förmigen Doppelanker versehen ist, dessen einer Teil das zugehörige Polpaar in der Haltestellung und dessen anderer Teil das zugehörige Polpaar in der Auslösestellung überbrückt, und daß der Auslösemagnet die Stromspulen auf den beiden Schenkeln zwischen den Polpaaren und die Spannungsspulen auf den beiden Schenkeln zwischen dem einen Polpaar und dem Joch trägt.The invention relates to an embodiment of such a device. The essence of the invention is that the two lines of force paths in one [J-shaped Magnetic system are generated, the two protruding from the legs inward with two and opposing pole pairs and provided with a J-shaped double armature is, one part of which is the associated pole pair in the holding position and the other Part bridges the associated pole pair in the release position, and that the release magnet the current coils on the two legs between the pole pairs and the voltage coils on the two legs between the one pair of poles and the yoke.
In der Abbildung ist die Einrichtung dargestellt. Das Magnetgestell 1o hat zwei Polpaare 12 und 13 und dementsprechend auch zwei Spannungsspulen 151 und 152 und zwei Stromspulen 161 und 162. Die beiden Zweige des Doppelankers 41, 142 sind durch einen Steg 1g aus urimagnetischem Material miteinander verbunden. Solange der durch den Schalter 18 fließende Strom eine zulässige normale Stärke nicht überschreitet, wirkt im wesentlichen der konstante Strom in den Erregerwicklungen 151, 152 und hält den unteren Magnetkreis durch Überbrückung der Pole z2 durch den Anker 141 entgegen dem Druck der Feder 17 geschlossen. Der Kraft fluß in dem oberen Magnetkreis ist infolge dies großen Luftspaltes nur schwach. Überschreitet aber der Strom in den Stromspulen 161, r62 das zugehörige Maß, so wird die Zugkraft des oberen Polpaares 13 verstärkt, die des unteren Polpaares 12 geschwächt. Der obere Anker 142 wird von seinem Polpaar 13 angezogen, der untere Anker 141 losgelassen, wodurch der Schalter 18 unter Entspannung der Feder 17 mit großer Schnelligkeit geöffnet wird.The setup is shown in the illustration. The magnetic frame 1o has two pole pairs 12 and 13 and accordingly also two voltage coils 151 and 152 and two current coils 161 and 162. The two branches of the double armature 41, 142 are connected to one another by a web 1g made of urimagnetic material. As long as the current flowing through the switch 18 is an allowable normal level does not exceed the constant current in the excitation windings 151, 152 and holds the lower magnetic circuit by bridging the poles z2 through the Armature 141 closed against the pressure of spring 17. The flow of power in the upper one Due to this large air gap, the magnetic circuit is only weak. But exceeds the current in the current coils 161, r62 the associated measure, then the tensile force of the the upper pair of poles 13 reinforced, those of the lower pair of poles 12 weakened. The upper Armature 142 is attracted by its pole pair 13, the lower armature 141 is released, whereby the switch 18 with relaxation of the spring 17 with great rapidity is opened.
