Die Erfindung betrifft einen Auslösemagneten für Ölschalter und besteht darin, daß der Magnetanker beim Ansprechen eine Klinke bewegt, die einen Kniehebel freigibt, so -daß eine zwischen den freien Drehachsen desselben gespannte Feder sich entspannen kann, dabei den Kniehebel beugt und gleichzeitig ein Schaltstück auf die Auslösevorrichtung des Ölschalters fallen läßt.The invention relates to a release magnet for oil switches and consists in that the Magnetic armature when responding moves a pawl that releases a toggle lever, so that a spring tensioned between its free axes of rotation can relax, in doing so, the knee lever bends and at the same time a contact piece on the release device the oil switch drops.
Fig. ι der Zeichnung zeigt ein Ausführungsbeispiel des Auslösemagneten nach der Erfindung in der Einschaltstellung und Fig. 2 die Lage des Kniehebels und der von ihmFig. Ι of the drawing shows an embodiment of the release magnet according to the invention in the switched-on position and FIG. 2 the location of the knee lever and that of it
„ betätigten Teile des Auslösemagneten nach dem Ansprechen des " Magnetankers."Actuated parts of the release magnet after the" magnet armature has responded.
Sobald gemäß Fig. 1 die Magnetspule 1 erregt wird, spricht der Magnetanker 2 an. Er dreht sich um eine Achse 12 und drückt dabei auf die Klinke 3, deren Nase 13 nun die mit ihr verklinkte Nase 14 des Kniehebelarmes 5 freigibt. Dadurch wird die zwischen den Drehpunkten 16, 17 der beiden Arme 4, 5As soon as the magnet coil 1 is excited according to FIG. 1, the magnet armature 2 responds. It rotates around an axis 12 and presses on the pawl 3, the nose 13 of which is now the nose 14 of the toggle lever arm 5, which is latched to it, releases. This will make the between the pivot points 16, 17 of the two arms 4, 5
, des Kniehebels vorgesehene vorgespannte Feder 7 entspannt, beugt dabei den Kniehebel und läßt das Schaltstück 6 um einen durch den Schlitz 15 begrenzten Weg fallen, das, the pretensioned spring 7 provided for the toggle lever relaxes, thereby bending the toggle lever and lets the contact piece 6 fall by a path limited by the slot 15, the
' am Ende der Bewegung auf die Auslösevortung des Ölschalters schlagartig auftrifft. Das Schaltstück 6 ist angelenkt an dem einarmigen Hebel 9, der um "eine feste Achse 18 drehbar ■ ist, so daß schließlich das ganze Hebelsystem in die gemäß Fig. 2 dargestellte Lage übergeführt wird.'At the end of the movement, the triggering edge of the oil switch suddenly hits. That Switching piece 6 is hinged to the one-armed lever 9, which can be rotated about a fixed axis 18 ■ is, so that finally the entire lever system in the position shown in FIG is convicted.
Wird nun die Magnetspule 1 stromlos, so wird der Magnetanker 2 durch die Feder 21 wieder in seine Ausgangsstellung gemäß Fig. 1 , zurückgeführt. Sein Druck auf die Klinke 3 hört auf. Der Hebel 9 wird beim Einschalten des Schalters selbsttätig wieder in seine Einschaltstellung zurückgeführt und mit ihm 4q das Schaltstück 6. Dabei erhält die Feder 7 wieder eine Vorspannung. Unter dem Einfluß der Torsionsfeder 10 wird der Kniehebel 4, 5 wieder gestreckt. Dabei muß die Nase 14 des Kniehebelarmes 5 über die Nase 13 der Klinke 3 geschoben werden. Dies könnte beispielsweise durch Zusammendrücken der Feder 8 erreicht werden. Für diese Bewegung ist jedoch infolge der ungünstigen Verhältnisse im Kniehebel in der Einschaltstellung eine große Kraft erforderlich. Um diesen Nachteil zu beseitigen, ist der Kniehebelarm 5 mit einem Längsschlitz 11 versehen, welcher beim Zuklappen des Kniehebels gestattet, den Hebelarm 4 und mit ihm die Klinke 3 so hoch zu heben, daß die Nasen 13 und 14 des Hebelarmes 5 und der Klinke 3 aneinander vorbeigehen können, ohne die Feder 8 zu spannen.If the magnet coil 1 is now de-energized, the magnet armature 2 is de-energized by the spring 21 returned to its original position according to FIG. His pressure on the handle 3 stop. The lever 9 automatically returns to its position when the switch is turned on The switch-on position is returned and with it 4q the contact element 6. The spring 7 is thereby given again a bias. Under the influence of the torsion spring 10, the toggle lever 4, 5 stretched again. The nose 14 of the toggle arm 5 must be on the Nose 13 of the pawl 3 are pushed. This could be done, for example, by squeezing the spring 8 can be achieved. For this movement, however, is due to the unfavorable Conditions in the toggle lever in the on position require a great deal of force. Around to eliminate this disadvantage, the toggle lever arm 5 is provided with a longitudinal slot 11, which when closing the toggle lever allows the lever arm 4 and with it to lift the pawl 3 so high that the Noses 13 and 14 of the lever arm 5 and the pawl 3 can pass each other, without tensioning the spring 8.
Werden Klinke 3 und Kniehebel 4, 5 in der entgegengesetzten Stellung derart auf den Drehachsen 16, 17 befestigt, daß der Ansatz 19 der Klinke über den Anschlag 20 des Magnetankers zu liegen kommt, so läßt sich die Einrichtung auch für Nullspannungsauslösungverwenden. Der abfallende Magnet-Are pawl 3 and toggle levers 4, 5 in the opposite position in such a way the axes of rotation 16, 17 attached that the approach 19 of the pawl over the stop 20 of the If the magnet armature comes to rest, the device can also be used for zero voltage release. The falling magnet
anker 2 hebt in diesem Falle die Klinke, die sich entspannende Feder 7 beugt _den Kniehebel und läßt das Schaltstück 6 auf die Auslösevorrichtung des Ölschalters fallen.In this case, anchor 2 lifts the pawl, the relaxing spring 7 bends the knee lever and leaves the contact piece 6 on the tripping device of the oil switch fall.
