Definitions
- the present invention relates to an electromechanical circuit breaker with a rotary drive which can be rotated about an axis of rotation, a drive element, a contact bridge support, at least one contact bridge and mating contacts,
- the rotary drive can be rotated between an on and an off position and acts on the contact bridge support via the drive element
- the at least one contact bridge when the rotary drive is turned into the on position, the at least one contact bridge can be lowered onto the mating contacts by means of the contact bridge carrier, - In the case of a non-welded contact bridge when the rotary actuator is turned into the off position, the at least one contact bridge by means of the contact bridge carrier from the counter contacts can be lifted off,
- the drive element is pressed against the rotary drive when the contact bridge is not welded to the mating contacts.
- Circuit breakers of this type are generally known. In particular, they must meet the requirements of IEC 947 Part 1. This means that the rotary drive of such a circuit breaker must not be able to be set to the off position up to a torque specified in IEC 947 Part 1 if the contact bridge is welded to the mating contacts.
- the object of the present invention is to design a circuit breaker in such a way that the rotary drive, when the contact bridge is welded to the mating contacts, cannot be brought into the off position even with the use of additional parts, or only with significantly increased effort.
- the object is achieved in that the drive element is held by the contact bridge support in a position in which it blocks rotation of the rotary drive into the off position when the contact bridge is welded to the mating contacts.
- the rotary drive and the drive element generally also come into contact at a second radial distance that is smaller than the first radial distance.
- the rotary drive would only interact with the drive element in the case of a contact bridge welded to the mating contacts in the absence of the profiles in the second radial distance.
- the drive element is generally arranged such that it can be rotated about a drive axis which runs parallel to a plane normal to the axis of rotation. Because then the circuit breaker is particularly simple in construction. If in this case the drive element is immovably mounted with respect to the drive axis, the profiles come into contact with one another at a site of action when the contact bridge is welded to the counter-contacts and a vector perpendicular to the axis of rotation to the site of action runs essentially parallel to a plane normal to the drive axis blocking the rotary drive is particularly effective.
- the drive element acts on the contact bridge support via a deflection mechanism, in particular a knee joint mechanism
- the effective chain from the rotary drive to the contact bridge support can be designed more flexibly.
- FIG 2 is a perspective view of the section of
- an electromagnetic circuit breaker has a rotary drive 1.
- the rotary drive 1 is rotatable about an axis of rotation 2. It has two end positions. One end position is called the off position below. It is shown in FIGS. 3 and 4. The other end position is called the on position below. It is shown in FIGS. 1, 2, 5 and 6.
- a drive element 3 is rotatably mounted below the rotary drive 1 about a drive axis 4.
- the drive axis 4 runs parallel to (or in) a plane that is normal (perpendicular) to the axis of rotation 2.
- the drive element 3 is axially immovable with respect to the drive axis 4.
- the rotary drive 1 acts on the contact bridge support 5 via the drive element 3.
- the drive element 3 does not act directly on the contact bridge support 5, but via a deflection mechanism 6.
- the deflection mechanism 6, which according to the exemplary embodiment is designed as a knee joint mechanism 6, could but also eliminated.
- the contact bridge support 5 is preloaded by means of a spring element 7. As a result, a force is also exerted on the drive element 3, so that the drive element 3 is pressed against the rotary drive 1.
- the electromagnetic circuit breaker also has at least one switchable electrical contact 8. It can be seen from FIGS. 3, 5 and 7 that there are even three such contacts 8. If necessary, however, more or fewer than three such contacts 8 could also be present. Each contact 8 has a movable contact bridge 9 and fixed counter contacts 10.
- the contact bridges 9 and the mating contacts 10 are not welded to one another. In this case, the drive element 3 remains pressed against the rotary drive 1 even during the (manual) return of the rotary drive 1 from the on position to the off position. In the case of contact bridges 9 which are not welded to the mating contacts 10, this results in when the rotary drive 1 is rotated from the on to the off position, the contact bridges 9 are also lifted off the counter contacts 10 by means of the contact bridge carrier 5.
- the rotary drive 1 and the drive element 3 have profiles 11, 12. As can be seen from FIG. 3 and even more clearly from FIG. 4, the profiles 11, 12 are matched to one another in such a way that they do not come into contact with one another if the contact bridges 9 are not welded to the counter-contacts 10. If, on the other hand, at least one of the contact bridges 9 is welded to its corresponding mating contacts 10, the contact bridge carrier 5 cannot move downward. As a result, the drive element 3 is held by the contact bridge carrier 5 in a position in which the profiles 11, 12 come into contact with one another. This state is shown in FIGS. 7 and 8.
- the profiles 11, 12 come into contact with one another at a site of action which has a first radial distance L 1 from the axis of rotation 2.
- a vector V is perpendicular to the axis of rotation 2 and points to the site of action. This vector V runs parallel to (or in) a plane that runs normal (perpendicular) to the drive axis 4. Due to the axially immovable mounting of the drive element 3 on the drive shaft 4, it is thus achieved that rotation of the rotary drive 1 into the off position is blocked by the contact of the profiles. The operator thus receives tactile feedback about the fault condition “welded contact bridge 9 *.
- the rotary drive 1 and the drive element 3 also come into contact with one another at a second radial distance L2.
- the second radial distance L2 is smaller than the first radial distance L1.
- this second contact did not occur between the rotary drive 1 and the drive element 3, ie a small remaining distance L3 would remain at point 13.
- the rotary drive 1 would only interact with the drive element 3 at the second radial distance L2 if the profiles 11, 12 were missing.

Abstract
An electromagnetic power switch comprising a rotary actuator (1) which can rotated between an on-position and an off-position and which acts upon a contact bridge carrier (5) by means of a drive element (3). Rotation into the on-position enables at least one contact bridge (9) to be lowered onto counter contacts (10) by means of said contact bridge carrier (5). If the contact bridge (9) is not welded to the counter contacts, the contact bridge (9) can be raised from the counter contacts (10) via said contact bridge carrier (5) when rotation occurs into the off-position. If the contact bridge (9) is not welded, the drive element (3) is pressed onto the rotary actuator (1). If the contact bridge (9) is welded, the drive element (3) is maintained by the contact bridge carrier (5) in a position which prevents the rotary actuator (1) from rotating into the off-position.

Elektromagnetischer LeistungsschalterElectromagnetic circuit breaker
Die vorliegende Erfindung betrifft einen elektromechanischen Leistungsschalter, mit einem um eine Drehachse drehbaren Drehantrieb, einem Antriebselement, einem Kontaktbruckentrager, mindestens einer Kontaktbrücke und Gegenkontakten,The present invention relates to an electromechanical circuit breaker with a rotary drive which can be rotated about an axis of rotation, a drive element, a contact bridge support, at least one contact bridge and mating contacts,
- wobei der Drehantrieb zwischen einer Ein- und einer Aus- Stellung verdrehbar ist und über das Antriebselement auf den Kontaktbruckentrager wirkt,the rotary drive can be rotated between an on and an off position and acts on the contact bridge support via the drive element,
- wobei bei Verdrehen des Drehantriebs in die Ein-Stellung die mindestens eine Kontaktbrücke mittels des Kontaktbrückenträgers auf die Gegenkontakte absenkbar ist, - wobei bei mit den Gegenkontakten nicht verschweißter Kontaktbrücke bei Verdrehen des Drehantriebs in die Aus- Stellung die mindestens eine Kontaktbrücke mittels des Kontaktbrückenträgers von den Gegenkontakten abhebbar ist,- Wherein when the rotary drive is turned into the on position, the at least one contact bridge can be lowered onto the mating contacts by means of the contact bridge carrier, - In the case of a non-welded contact bridge when the rotary actuator is turned into the off position, the at least one contact bridge by means of the contact bridge carrier from the counter contacts can be lifted off,
- wobei das Antriebselement bei mit den Gegenkontakten nicht verschweißter Kontaktbrücke an den Drehantrieb angedrückt wird.- The drive element is pressed against the rotary drive when the contact bridge is not welded to the mating contacts.
Derartige Leistungsschalter sind allgemein bekannt. Sie müssen insbesondere die Anforderungen nach IEC 947-Teil 1 erfül- len. Das heißt, der Drehantrieb eines solchen Leistungsschalters darf bis zu einem in der IEC 947-Teil 1 angegebenen Drehmoment nicht in die Aus-Stellung gebracht werden können, wenn die Kontaktbrücke mit den Gegenkontakten verschweißt ist.Circuit breakers of this type are generally known. In particular, they must meet the requirements of IEC 947 Part 1. This means that the rotary drive of such a circuit breaker must not be able to be set to the off position up to a torque specified in IEC 947 Part 1 if the contact bridge is welded to the mating contacts.
Insbesondere vorhandene Toleranzen und Elastizitäten führen in der Praxis dazu, dass der Drehantrieb trotz verschweißter Kontaktbrücke mit einem Drehmoment unterhalb des vorgeschriebenen Ausschaltdrehmoments in die Aus-Stellung gebracht wer- den kann. Die Norm kann daher im Stand der Technik nur mit Hilfe von Zusatzteilen erfüllt werden.
Die Aufgabe der vorliegenden Erfindung besteht darin, einen Leistungsschalter derart auszugestalten, dass der Drehantrieb bei mit den Gegenkontakten verschweißter Kontaktbrücke auch ohne Verwendung von Zusatzteilen nicht bzw. nur mit deutlich erhöhtem Kraftaufwand in die Aus-Stellung gebracht werden kann.In practice, existing tolerances and elasticities mean that, despite the welded contact bridge, the rotary drive can be brought into the off position with a torque below the specified switch-off torque. In the prior art, the standard can therefore only be met with the help of additional parts. The object of the present invention is to design a circuit breaker in such a way that the rotary drive, when the contact bridge is welded to the mating contacts, cannot be brought into the off position even with the use of additional parts, or only with significantly increased effort.
Die Aufgabe wird dadurch gelöst, dass das Antriebselement bei mit den Gegenkontakten verschweißter Kontaktbrücke vom Kon- taktbrückenträger in einer Stellung gehalten wird, in der es ein Verdrehen des Drehantriebs in die Aus-Stellung blockiert.The object is achieved in that the drive element is held by the contact bridge support in a position in which it blocks rotation of the rotary drive into the off position when the contact bridge is welded to the mating contacts.
Eine konstruktive Lösung dieses Prinzips ist beispielsweise dadurch gegeben, - dass der Drehantrieb und das Antriebselement Profilierungen aufweisen,A constructive solution to this principle is given, for example, by the fact that the rotary drive and the drive element have profiles,
- dass die Profilierungen bei mit den Gegenkontakten nicht verschweißter Kontaktbrücke nicht miteinander in Kontakt kommen, - dass die Profilierungen bei mit den Gegenkontakten verschweißter Kontaktbrücke in einem ersten Radialabstand von der Drehachse miteinander in Kontakt kommen und- that the profiles do not come into contact with one another when the contact bridge is not welded to the counter contacts, - that the profiles come into contact with one another at a first radial distance from the axis of rotation when the contact bridge is welded to the counter contacts and
- dass durch den Kontakt der Profilierungen das Verdrehen des Drehantriebs in die Aus-Stellung blockiert wird.- That the rotation of the rotary drive is blocked in the off position by the contact of the profiles.
In der Praxis kommen der Drehantrieb und das Antriebselement bei mit den Gegenkontakten verschweißter Kontaktbrücke in der Regel auch in einem zweiten Radialabstand in Kontakt, der kleiner als der erste Radialabstand ist. Idealerweise aber würde der Drehantrieb bei mit den Gegenkontakten verschweißter Kontaktbrücke nur bei Fehlen der Profilierungen in dem zweiten Radialabstand mit dem Antriebselement zusammenwirken.In practice, when the contact bridge is welded to the mating contacts, the rotary drive and the drive element generally also come into contact at a second radial distance that is smaller than the first radial distance. Ideally, however, the rotary drive would only interact with the drive element in the case of a contact bridge welded to the mating contacts in the absence of the profiles in the second radial distance.
Das Antriebselement ist in der Regel derart angeordnet, dass es um eine Antriebsachse drehbar ist, welche parallel zu einer zur Drehachse normalen Ebene verläuft. Denn dann ist der Leistungsschalter konstruktiv besonders einfach ausgebildet.
Wenn in diesem Fall das Antriebselement bezüglich der Antriebsachse unverschieblich gelagert ist, die Profilierungen bei mit den Gegenkontakten verschweißter Kontaktbrücke an einem Wirkort miteinander in Kontakt kommen und ein auf der Drehachse senkrecht stehender Vektor zum Wirkort im Wesentlichen parallel zu einer zur Antriebsachse normalen Ebene verläuft, ist das Blockieren des Drehantriebs besonders wirksam.The drive element is generally arranged such that it can be rotated about a drive axis which runs parallel to a plane normal to the axis of rotation. Because then the circuit breaker is particularly simple in construction. If in this case the drive element is immovably mounted with respect to the drive axis, the profiles come into contact with one another at a site of action when the contact bridge is welded to the counter-contacts and a vector perpendicular to the axis of rotation to the site of action runs essentially parallel to a plane normal to the drive axis blocking the rotary drive is particularly effective.
Wenn das Antriebselement über einen Umlenkmechanismus, insbe- sondere einen Kniegelenkmechanismus, auf den Kontaktbruckentrager wirkt, ist die Wirkkette vom Drehantrieb zum Kontaktbruckentrager flexibler gestaltbar.If the drive element acts on the contact bridge support via a deflection mechanism, in particular a knee joint mechanism, the effective chain from the rotary drive to the contact bridge support can be designed more flexibly.
Weitere Vorteile und Einzelheiten ergeben sich aus der nach- folgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit den Zeichnungen. Dabei zeigen in PrinzipdarstellungFurther advantages and details emerge from the following description of an exemplary embodiment in conjunction with the drawings. Show in principle
FIG 1 einen Schnitt durch einen elektromagnetischen1 shows a section through an electromagnetic
Leistungsschalter, FIG 2 eine perspektivische Ansicht des Schnitts vonCircuit breaker, FIG 2 is a perspective view of the section of
FIG 1, FIG 3, 7 und 7 Schnitte durch den Leistungsschalter der FIG1, 3, 7 and 7 sections through the circuit breaker of FIG
1 und 2 längs der Linie A-A in FIG 1 und FIG 4, 6 und 8 Schnitte durch den Leistungsschalter der FIG 1 und 2 längs der Linie B-B in FIG 1.1 and 2 along the line A-A in FIG. 1 and FIG. 4, 6 and 8 sections through the circuit breaker of FIGS. 1 and 2 along the line B-B in FIG. 1.
Gemäß den FIG 1 und 2 weist ein elektromagnetischer Leistungsschalter einen Drehantrieb 1 auf. Der Drehantrieb 1 ist um eine Drehachse 2 drehbar. Er weist zwei Endstellungen auf. Die eine Endstellung wird nachstehend Aus-Stellung genannt. Sie ist in den FIG 3 und 4 dargestellt. Die andere Endstellung wird nachfolgend Ein-Stellung genannt. Sie ist in den FIG 1, 2, 5 und 6 dargestellt.1 and 2, an electromagnetic circuit breaker has a rotary drive 1. The rotary drive 1 is rotatable about an axis of rotation 2. It has two end positions. One end position is called the off position below. It is shown in FIGS. 3 and 4. The other end position is called the on position below. It is shown in FIGS. 1, 2, 5 and 6.
Ein Antriebselement 3 ist unterhalb des Drehantriebs 1 um eine Antriebsachse 4 drehbar gelagert. Die Antriebsachse 4 verläuft dabei parallel zu (bzw. in) einer Ebene, die normal
(senkrecht) zur Drehachse 2 verläuft. Das Antriebselement 3 ist bezüglich der Antriebsachse 4 axial unverschieblich gelagert.A drive element 3 is rotatably mounted below the rotary drive 1 about a drive axis 4. The drive axis 4 runs parallel to (or in) a plane that is normal (perpendicular) to the axis of rotation 2. The drive element 3 is axially immovable with respect to the drive axis 4.
Der Drehantrieb 1 wirkt über das Antriebselement 3 auf einen Kontaktbruckentrager 5. Im vorliegenden Fall wirkt dabei das Antriebselement 3 nicht direkt, sondern über einen Umlenkmechanismus 6 auf den Kontaktbruckentrager 5. Der Umlenkmechanismus 6, der gemäß Ausführungsbeispiel als Kniegelenkmecha- nismus 6 ausgebildet ist, könnte aber auch entfallen.The rotary drive 1 acts on the contact bridge support 5 via the drive element 3. In the present case, the drive element 3 does not act directly on the contact bridge support 5, but via a deflection mechanism 6. The deflection mechanism 6, which according to the exemplary embodiment is designed as a knee joint mechanism 6, could but also eliminated.
Der Kontaktbruckentrager 5 ist mittels eines Federelements 7 vorbelastet. Dadurch wird auch auf das Antriebselement 3 eine Kraft ausgeübt, so dass das Antriebselement 3 an den Drehan- trieb 1 angedrückt wird.The contact bridge support 5 is preloaded by means of a spring element 7. As a result, a force is also exerted on the drive element 3, so that the drive element 3 is pressed against the rotary drive 1.
Der elektromagnetische Leistungsschalter weist ferner mindestens einen schaltbaren elektrischen Kontakt 8 auf. Aus den FIG 3, 5 und 7 ist dabei ersichtlich, dass sogar drei derar- tige Kontakte 8 vorhanden sind. Gegebenenfalls könnten aber auch mehr oder weniger als drei derartige Kontakte 8 vorhanden sein. Jeder Kontakt 8 weist eine bewegliche Kontaktbrücke 9 und feststehende Gegenkontakte 10 auf.The electromagnetic circuit breaker also has at least one switchable electrical contact 8. It can be seen from FIGS. 3, 5 and 7 that there are even three such contacts 8. If necessary, however, more or fewer than three such contacts 8 could also be present. Each contact 8 has a movable contact bridge 9 and fixed counter contacts 10.
Beim Verdrehen des Drehantriebs 1 durch die Bedienperson von der Aus- in die Ein-Stellung wird der Kontaktbruckentrager 5 gegen die Federkraft des Federelements 7 nach oben ausgelenkt . Dadurch werden - siehe FIG 5 und 6 - die Kontaktbrücken 9 auf die korrespondierenden Gegenkontakte 10 abgesenkt.When the rotary drive 1 is rotated by the operator from the off to the on position, the contact bridge support 5 is deflected upward against the spring force of the spring element 7. As a result - see FIGS. 5 and 6 - the contact bridges 9 are lowered onto the corresponding mating contacts 10.
Bei ordnungsgemäßem Funktionieren des elektromagnetischen Leistungsschalters sind die Kontaktbrücken 9 und die Gegenkontakte 10 nicht miteinander verschweißt. In diesem Fall bleibt das Antriebselement 3 auch während des (manuellen) Rückführens des Drehantriebs 1 von der Ein- in die Aus-Stellung an den Drehantrieb 1 angedrückt. Bei mit den Gegenkontakten 10 nicht verschweißten Kontaktbrücken 9 werden dadurch
beim Verdrehen des Drehantriebs 1 von der Ein- in die Aus- Stellung auch die Kontaktbrücken 9 mittels des Kontaktbrückenträgers 5 von den Gegenkontakten 10 abgehoben.If the electromagnetic circuit breaker functions properly, the contact bridges 9 and the mating contacts 10 are not welded to one another. In this case, the drive element 3 remains pressed against the rotary drive 1 even during the (manual) return of the rotary drive 1 from the on position to the off position. In the case of contact bridges 9 which are not welded to the mating contacts 10, this results in when the rotary drive 1 is rotated from the on to the off position, the contact bridges 9 are also lifted off the counter contacts 10 by means of the contact bridge carrier 5.
Der Drehantrieb 1 und das Antriebselement 3 weisen Profilierungen 11, 12 auf. Wie aus FIG 3 und noch deutlicher aus FIG 4 ersichtlich ist, sind die Profilierungen 11, 12 derart aufeinander abgestimmt, dass sie nicht miteinander in Kontakt kommen, wenn die Kontaktbrücken 9 nicht mit den Gegenkontak- ten 10 verschweißt sind. Wenn hingegen mindestens eine der Kontaktbrücken 9 mit ihren korrespondierenden Gegenkontakten 10 verschweißt ist, kann der Kontaktbruckentrager 5 sich nicht nach unten bewegen. Dadurch wird das Antriebselement 3 vom Kontaktbruckentrager 5 in einer Stellung gehalten, in der die Profilierungen 11, 12 miteinander in Kontakt kommen. Dieser Zustand ist in den FIG 7 und 8 dargestellt.The rotary drive 1 and the drive element 3 have profiles 11, 12. As can be seen from FIG. 3 and even more clearly from FIG. 4, the profiles 11, 12 are matched to one another in such a way that they do not come into contact with one another if the contact bridges 9 are not welded to the counter-contacts 10. If, on the other hand, at least one of the contact bridges 9 is welded to its corresponding mating contacts 10, the contact bridge carrier 5 cannot move downward. As a result, the drive element 3 is held by the contact bridge carrier 5 in a position in which the profiles 11, 12 come into contact with one another. This state is shown in FIGS. 7 and 8.
Wie aus den FIG 7 und 8 ersichtlich ist, kommen die Profilierungen 11, 12 an einem Wirkort miteinander in Kontakt, der einen ersten Radialabstand Ll von der Drehachse 2 aufweist. Wie aus den FIG 7 und 8 ferner ersichtlich ist, steht ein Vektor V senkrecht auf der Drehachse 2 und zeigt zum Wirkort. Dieser Vektor V verläuft parallel zu (bzw. in) einer Ebene, die normal (senkrecht) zur Antriebsachse 4 verläuft. Auf Grund der axial unverschieblichen Lagerung des Antriebselements 3 auf der Antriebsachse 4 wird somit erreicht, dass durch den Kontakt der Profilierungen ein Verdrehen des Drehantriebs 1 in die Aus-Stellung blockiert wird. Die Bedienperson erhält somit eine taktil erfassbare Rückmeldung über den Störzustand „verschweißte Kontaktbrücke 9* .As can be seen from FIGS. 7 and 8, the profiles 11, 12 come into contact with one another at a site of action which has a first radial distance L 1 from the axis of rotation 2. As can also be seen from FIGS. 7 and 8, a vector V is perpendicular to the axis of rotation 2 and points to the site of action. This vector V runs parallel to (or in) a plane that runs normal (perpendicular) to the drive axis 4. Due to the axially immovable mounting of the drive element 3 on the drive shaft 4, it is thus achieved that rotation of the rotary drive 1 into the off position is blocked by the contact of the profiles. The operator thus receives tactile feedback about the fault condition “welded contact bridge 9 *.
Wenn mindestens eine der Kontaktbrücken 9 mit ihren korrespondierenden Gegenkontakten 10 verschweißt ist, kommen - siehe insbesondere FIG 8 - der Drehantrieb 1 und das Antriebs- element 3 auch in einem zweiten Radialabstand L2 miteinander in Kontakt. Der zweite Radialabstand L2 ist dabei kleiner als der erste Radialabstand Ll . Noch besser wäre es hingegen,
wenn zwischen dem Drehantrieb 1 und dem Antriebselement 3 dieser zweite Kontakt nicht aufträte, an der Stelle 13 also ein geringer Restabstand L3 verbliebe. In diesem Fall würde der Drehantrieb 1 mit dem Antriebselement 3 in dem zweiten Radialabstand L2 nur dann zusammenwirken, wenn die Profilierungen 11, 12 fehlten.If at least one of the contact bridges 9 is welded to its corresponding mating contacts 10, see in particular FIG. 8, the rotary drive 1 and the drive element 3 also come into contact with one another at a second radial distance L2. The second radial distance L2 is smaller than the first radial distance L1. However, it would be even better if this second contact did not occur between the rotary drive 1 and the drive element 3, ie a small remaining distance L3 would remain at point 13. In this case, the rotary drive 1 would only interact with the drive element 3 at the second radial distance L2 if the profiles 11, 12 were missing.
Mittels des erfindungsgemäß ausgestalteten elektromagnetischen Leistungsschalters ist auf einfache Weise eine normge- rechte Funktion erreichbar, ohne dass hierzu zusätzliche Bauelemente benötigt werden.
By means of the electromagnetic circuit breaker designed according to the invention, a function conforming to standards can be achieved in a simple manner without additional components being required for this.
