Definitions
- the invention relates to an electromagnetic release with a coil, an armature, a cooperating with this, displaceable in the coil plunger, a coil electrically connected to the yoke through which the plunger is guided or on which the plunger is guided, and one Anchor with a force acting on spring.
- a trigger is for example from the DE 101 26 851 C1 or the DE 101 26 854 A1 known.
- the from the DE 101 26 851 C1 known electromagnetic release in particular for a circuit breaker, has an integrally formed with a magnetic yoke magnetic core, which is disposed within the cross section of the trip coil and is provided with a central opening for carrying a tappet connected to a movable armature.
- the electromagnetic release is often due to the relatively large diameter of the trip coil that component, which dictates the minimum width of the circuit breaker.
- a relatively narrow cross-section of a coil of a magnetic release can be achieved by a non-circular coil cross section for a given cross-sectional area, this construction area is more complex in terms of manufacturing technology compared to coils with a circular cross section.
- the from the DE 101 26 854 A1 known electromagnetic release of the generic type has an armature which has a part arranged outside the coil, and which is guided in the recess of a leg of the yoke.
- the invention has for its object to provide an electromagnetic release for a circuit breaker, in particular circuit breaker, which in a simple Construction, in particular with a circular coil cross-section, is constructed particularly narrow.
- This electromagnetic release has the known principle in Tauchankersystemen components coil, magnetic yoke, armature, plunger and spring.
- an air gap between the magnetic yoke or magnetic core and the armature is formed outside the coil.
- the anchor is displaceable along the coil axis like a conventional plunger armature. In this way, there are advantages in terms of the impact of the anchor, which are not available for example in hinged armature systems.
- the diameter of the tripping coil can be particularly small, since the "core" of the magnetic yoke is virtually displaced outwards next to the coil.
- the magnetic yoke 2 preferably has yoke legs arranged outside the coil, which cooperate with two armature legs which are also arranged at least approximately symmetrically with respect to the coil axis outside the coil.
- two air gaps are each formed between an armature leg and a yoke leg, which reinforce the impact of the armature in comparison to a design with only one air gap.
- it is ensured in this way that the armature is accelerated in response to the magnetic release exactly in the direction of the coil axis.
- the armature acting on the armature with a force against the triggering direction is preferably designed in a space-saving manner as a helical spring, which concentrically surrounds the tappet.
- the spring can either at least partially be located inside the coil or completely outside the coil.
- the former design has the advantage that a relatively long coil spring can be used, which provides a correspondingly long spring travel, while the second construction is characterized in that the diameter of the coil can be chosen even smaller. In any case, a simple plug-in installation of the individual parts of the shutter is possible.
- the anchor is made according to a first alternative in one piece with the plunger, preferably as a stamped part. A particularly efficient production is made possible by the fact that this combined component is completely flat.
- the armature and the plunger are formed as separate, cooperating with abutment surfaces components.
- This design has the advantage that different materials for the anchor on the one hand and the plunger on the other hand, in particular a plastic for the plunger, can be used on the one hand.
- the decoupling of the plunger from the anchor creates the possibility of providing additional actuation of the plunger by means of a further triggering element, in particular a bimetal strip. The typically much lower forces than the magnetic release generating bimetallic strip does not have to overcome the force of the magnet armature biasing spring upon actuation of the plunger.
- a circuit breaker typically has an arc guide rail adjoining the magnetic yoke of the electromagnetic release. If such an arc guide rail is provided at the trigger, this is preferably arranged such that there is between this and the trip coil of the displaceable armature leg or one of the displaceable armature leg. The anchor leg is thus well protected from the action of an arc.
- the armature and / or the plunger is guided in bearings formed by a housing shell of the trigger.
- both the required number of components of the switching device is optimized, as well as high precision with respect to the kinematics of the arranged in the switching device electromagnetic release achievable.
- the advantage of the invention is, in particular, that a particularly narrow structure of the release is given by the displacement of an air gap of an electromagnetic release designed in principle in the manner of a Tauchankersystems from inside the coil next to the coil.
- the FIG. 1 shows an electromagnetic release 1 of a circuit breaker, which in the same or modified Version could also be used with a motor protection switch, circuit breaker, contactor or relay.
- Essential components of the trigger 1 are a coil 2, a magnetic yoke 3 and an armature 4 with a plunger 5, which is made in this embodiment in one piece with the armature 4.
- the tappet 5 is moved in the direction of actuation R, thereby opening a switching mechanism (not shown).
- the armature 4 is biased against the direction of actuation R by the force of a spring 6 designed as a helical spring, which lies largely inside the coil 2 and surrounds the plunger 5 concentrically.
- a moving contact is lifted by a contact piece 7 connected to the yoke 3, whereby an arc is formed, for the discharge of which, inter alia, a branching off of the magnetic yoke 3, parallel to the coil axis A of the tripping coil 2 arranged arc guide rail 8 is provided.
- the magnetic yoke 3 has two outside of the coil 2 adjacent yoke legs 9,10, which lie opposite each forming an air gap 11,12 an armature leg 13,14 of the armature. While the magnetic yoke 3 is constructed asymmetrically with the yoke legs 9,10, the armature 4 is formed symmetrically approximately in E-shape, the plunger 5 is arranged as a central E-leg along the coil axis A and the magnet legs 13,14 the outer E -Skeleton form. Due to the symmetrical structure of the armature 4 ensures that when a response of the trigger 1, a force acting on the plunger 5 exclusively in the direction of actuation R. A deflection of the direction of movement, such as in hinged armature systems, is not required. The impact of the plunger 5 can be used directly for opening a contact formed on the contact piece 7.
- FIGS. 2 to 5 Further details of the electromagnetic release 1 are based on FIGS. 2 to 5 recognizable. especially the FIGS. 2 and 4 illustrate the very narrow construction of the trigger 12 with a width B, which corresponds to both the outer diameter of the coil 2 and the maximum width of the magnetic yoke 3, and a height H, which is about three times the width B.
- the width B is preferably less than 9 mm, so that two triggers 1 can be installed side by side in an 18 mm wide housing of a DIN rail mounted device.
- the magnet yoke 3 is made as a stamped and bent part, which is electrically connected to the coil 2 at a connection point 15.
- the armature 4 including the plunger 5 and the arc guide rail 8 are made as non-bent punched parts. Overall, this is a very production-friendly design of the trigger 1 is given.
- FIG. 3 is a housing shell 16 indicated, which bearing 17 for the armature 4 and the guided through an opening 18 of the magnetic yoke 3 ram 5 forms.
- the magnetic yoke 3 can be mounted directly in the housing shell 16. Instead of guiding the plunger 5 through the opening 18, for example, a bulge of the magnetic yoke 3 may be provided at the corresponding location, so that the plunger 5 is guided past the magnetic yoke 5.
- FIGS. 6 to 10 show a further embodiment of an electromagnetic release 1.
- the plunger 5 is a separate from the armature 4 and relative to this slidable component.
- the arranged in this case outside the coil 2 spring 6 acts exclusively on the armature 4 with a force.
- the plunger 5, however, can be moved virtually without effort in the direction of actuation R without actuation of the armature.
- This decoupling of the plunger 5 from the armature 4 is particularly suitable to actuation of the plunger 5 not only electromagnetically, but also by a second release mechanism, not shown, in particular a bimetallic release to provide.
- the plunger 5 is For this purpose, it is guided past a foot surface 19 of the armature 4 which is bent in this case, and has an actuating surface 20 on its end against which a bimetallic element can act, which only provides a relatively small force in comparison with the magnetic force acting on the armature 4 in the event of a short circuit.
- the plunger 5 can thus be displaced by the bimetallic element in the direction of actuation R and thus trigger a symbolically represented switching element 21.
- the trigger 1 thus serves not only as an electromagnetic, ie instantaneous responsive trigger but at the same time as an integral part of a delayed responsive overload switch.
- the trigger 1 after the FIGS. 6 to 10 has by the decoupling of the plunger 5 from the armature 4, is also in this case an extremely compact structure, in particular with respect to the embodiment of the 1 to 5 unexpanded width B, given.
Description
Die Erfindung betrifft einen elektromagnetischen Auslöser mit einer Spule, einem Anker, einem mit diesem zusammenwirkenden, in der Spule verschieblichen Stößel, einem mit der Spule elektrisch verbundenen Magnetjoch, durch welches der Stößel geführt ist oder an welchem der Stößel vorbei geführt ist, und einer den Anker mit einer Kraft beaufschlagenden Feder. Ein derartiger Auslöser ist beispielsweise aus der

Der Erfindung liegt die Aufgabe zugrunde, einen elektromagnetischen Auslöser für einen Schutzschalter, insbesondere Leitungsschutzschalter, anzugeben, welcher bei einfacher Konstruktion, insbesondere mit kreisrundem Spulenquerschnitt, besonders schmal aufgebaut ist.The invention has for its object to provide an electromagnetic release for a circuit breaker, in particular circuit breaker, which in a simple Construction, in particular with a circular coil cross-section, is constructed particularly narrow.
Diese Aufgabe wird erfindungsgemäß gelöst durch einen elektromagnetischen Auslöser mit den Merkmalen des Anspruchs 1.This object is achieved by an electromagnetic release with the features of claim 1.
Dieser elektromagnetische Auslöser weist die prinzipiell bei Tauchankersystemen bekannten Komponenten Spule, Magnetjoch, Anker, Stößel und Feder auf. Im Gegensatz zu bekannten Auslösern ist jedoch ein Luftspalt zwischen dem Magnetjoch bzw. Magnetkern und dem Anker außerhalb der Spule gebildet. Der Anker ist dabei wie ein herkömmlicher Tauchanker längs der Spulenachse verschiebbar. Auf diese Weise ergeben sich Vorteile hinsichtlich der Schlagwirkung des Ankers, welche beispielsweise bei Klappankersystemen nicht nutzbar sind. Der Durchmesser der Auslösespule kann besonders gering sein, da der "Kern" des Magnetjochs quasi nach außen neben die Spule verlagert ist. Der statt des Magnetkerns nach außen verlagerte Jochschenkel, welcher mit einem Ankerschenkel des Magnetankers zusammenwirkt, hat keinen Einfluss auf die minimale Breite des Schutzschalters, da das Magnetjoch sowie der Magnetanker nicht oder nicht wesentlich breiter als die Spule sind. Es ist daher möglich, zwei elektromagnetische Auslöser nebeneinander innerhalb eines genormten Gehäuses, insbesondere eines Reiheneinbaugerätes mit einer Breite von 18 mm, anzuordnen. Hierbei können rationell herzustellende rundgewickelte Spulen verwendet werden.This electromagnetic release has the known principle in Tauchankersystemen components coil, magnetic yoke, armature, plunger and spring. In contrast to known triggers, however, an air gap between the magnetic yoke or magnetic core and the armature is formed outside the coil. The anchor is displaceable along the coil axis like a conventional plunger armature. In this way, there are advantages in terms of the impact of the anchor, which are not available for example in hinged armature systems. The diameter of the tripping coil can be particularly small, since the "core" of the magnetic yoke is virtually displaced outwards next to the coil. The instead of the magnetic core displaced outwards yoke leg, which cooperates with an armature leg of the armature, has no effect on the minimum width of the circuit breaker, since the magnetic yoke and the armature are not or not significantly wider than the coil. It is therefore possible, two electromagnetic triggers side by side within a standardized housing, in particular a DIN rail mounted device with a width of 18 mm, to order. In this case, rationally produced round wound coils can be used.
Vorzugsweise weist das Magnetjoch 2 außerhalb der Spule angeordnete Jochschenkel auf, welche mit zwei ebenfalls außerhalb der Spule zumindest annähernd symmetrisch zur Spulenachse angeordneten Ankerschenkeln zusammenwirken. Hierdurch sind zwei Luftspalte jeweils zwischen einem Ankerschenkel und einem Jochschenkel gebildet, welche die Schlagwirkung des Ankers im Vergleich zu einer Ausbildung mit lediglich einem Luftspalt verstärken. Zudem ist auf diese Weise sichergestellt, dass der Anker beim Ansprechen des Magnetauslösers exakt in Richtung der Spulenachse beschleunigt wird.The
Die den Anker mit einer Kraft entgegen der Auslöserichtung beaufschlagende Feder ist in Raum sparender Weise bevorzugt als Schraubenfeder ausgebildet, welche den Stößel konzentrisch umgibt. Die Feder kann dabei entweder zumindest teilweise innerhalb der Spule oder vollständig außerhalb der Spule angeordnet sein. Die erstgenannte Bauweise hat den Vorteil, dass eine relativ lange Schraubenfeder verwendbar ist, welche einen entsprechend langen Federweg bereitstellt, während sich die zweite Bauweise dadurch auszeichnet, dass der Durchmesser der Spule nochmals geringer gewählt werden kann. In jedem Fall ist eine einfache Steckmontage der einzelnen Teile des Auslösers möglich.The armature acting on the armature with a force against the triggering direction is preferably designed in a space-saving manner as a helical spring, which concentrically surrounds the tappet. The spring can either at least partially be located inside the coil or completely outside the coil. The former design has the advantage that a relatively long coil spring can be used, which provides a correspondingly long spring travel, while the second construction is characterized in that the diameter of the coil can be chosen even smaller. In any case, a simple plug-in installation of the individual parts of the shutter is possible.
Der Anker ist nach einer ersten Alternative einstückig mit dem Stößel, vorzugsweise als Stanzteil, hergestellt. Eine besonders rationelle Fertigung ist dadurch ermöglicht, dass dieses kombinierte Bauteil vollständig eben ist.The anchor is made according to a first alternative in one piece with the plunger, preferably as a stamped part. A particularly efficient production is made possible by the fact that this combined component is completely flat.
Nach einer zweiten Alternative sind der Anker und der Stößel als getrennte, an Anschlagflächen zusammenwirkende Bauteile ausgebildet. Diese Bauform hat zum einen den Vorteil, dass unterschiedliche Materialien für den Anker einerseits und den Stößel andererseits, insbesondere ein Kunststoff für den Stößel, verwendet werden können. Zum anderen ist durch die Entkopplung des Stößels vom Anker die Möglichkeit geschaffen, eine zusätzliche Betätigung des Stößels durch ein weiteres Auslöseelement, insbesondere einen Bimetallstreifen, vorzusehen. Der typischerweise wesentlich geringere Kräfte als der Magnetauslöser erzeugende Bimetallstreifen muss bei der Betätigung des Stößels nicht die Kraft der den Magnetanker vorspannenden Feder überwinden.According to a second alternative, the armature and the plunger are formed as separate, cooperating with abutment surfaces components. This design has the advantage that different materials for the anchor on the one hand and the plunger on the other hand, in particular a plastic for the plunger, can be used on the one hand. On the other hand, the decoupling of the plunger from the anchor creates the possibility of providing additional actuation of the plunger by means of a further triggering element, in particular a bimetal strip. The typically much lower forces than the magnetic release generating bimetallic strip does not have to overcome the force of the magnet armature biasing spring upon actuation of the plunger.
Ein Leitungsschutzschalter weist typischerweise eine an das Magnetjoch des elektromagnetischen Auslösers anschließende Lichtbogenleitschiene auf. Sofern eine solche Lichtbogenleitschiene bei dem Auslöser vorgesehen ist, ist diese bevorzugt derart angeordnet, dass sich zwischen dieser und der Auslösespule der verschiebliche Ankerschenkel bzw. einer der verschieblichen Ankerschenkel befindet. Der Ankerschenkel ist somit gut vor der Einwirkung eines Lichtbogens geschützt.A circuit breaker typically has an arc guide rail adjoining the magnetic yoke of the electromagnetic release. If such an arc guide rail is provided at the trigger, this is preferably arranged such that there is between this and the trip coil of the displaceable armature leg or one of the displaceable armature leg. The anchor leg is thus well protected from the action of an arc.

Der Vorteil der Erfindung liegt insbesondere darin, dass durch die Verlagerung eines Luftspaltes eines prinzipiell in der Art eines Tauchankersystems ausgebildeten elektromagnetischen Auslösers vom Spuleninneren neben die Spule ein besonders schmaler Aufbau des Auslösers gegeben ist.The advantage of the invention is, in particular, that a particularly narrow structure of the release is given by the displacement of an air gap of an electromagnetic release designed in principle in the manner of a Tauchankersystems from inside the coil next to the coil.

Das Magnetjoch 3 weist zwei außen an der Spule 2 anliegende Jochschenkel 9,10 auf, welche unter Bildung jeweils eines Luftspaltes 11,12 je einem Ankerschenkel 13,14 des Ankers 4 gegenüberliegen. Während das Magnetjoch 3 mit den Jochschenkeln 9,10 unsymmetrisch aufgebaut ist, ist der Anker 4 etwa in E-Form symmetrisch ausgebildet, wobei der Stößel 5 als mittlerer E-Schenkel längs der Spulenachse A angeordnet ist und die Magnetschenkel 13,14 die äußeren E-Schenkel bilden.
