Description
Die vorliegende Erfindung betrifft eine Magnetkammer für ein elektromagnetisches Niederspannungsschaltgerät, insbesondere einen Kompaktwendestarter, das in der Regel zwei Magnetantriebe aufweist, wobei jeder Magnetantrieb einen Hauptschieber betätigt. Die interne Schaltung ist so ausgeführt, dass jedem Magnetantrieb eine unterschiedliche Motorlaufrichtung zugewiesen ist. Ferner betrifft die Erfindung ein elektromagnetisches Niederspannungsschaltgerät, insbesondere einen Kompaktwendestarter, das zwei Magnetantriebe aufweist, wobei jeder Magnetantrieb einen Hauptschieber betätigt.The present invention relates to a solenoid chamber for a low-voltage electromagnetic switching device, in particular a Kompaktwendestarter, which usually has two magnetic drives, each magnetic actuator actuates a main slide. The internal circuit is designed so that each magnetic drive is assigned a different motor running direction. Furthermore, the invention relates to a low-voltage electromagnetic switching device, in particular a Kompaktwendestarter having two magnetic drives, each magnetic actuator actuates a main slide.
Bei derzeitigen elektromechanischen Niederspannungsschaltgeräten, insbesondere der Baugröße S0/S00, ist eine Wendeverriegelung für die Verbraucherabzweige in Einzelaufstellung außerhalb des Gerätes verwirklicht. Dabei werden zwei Schütze parallel verdrahtet und dazu wird ein Leistungsschalter in Reihe geschaltet. Die Verriegelung wird durch Zusatzteile, beispielsweise einen Anker und ein Lager, realisiert, die zwischen den Schützantrieben montiert werden und die auf die Schaltstückträger wirken. Bei elektrischen Umkehrschützen wirkt die Verriegelung auf die Anker der Schützantriebe für die gegenseitige Blockierung. D.h., die Wendeverriegelung zur gegenseitigen Blockierung der Hauptantriebe verhindert das gleichzeitige Schließen der Hauptkontakte zur Drehrichtungsänderung.In current low-voltage electromechanical switching devices, in particular the size S0 / S00, a turning lock for the load feeders in a single installation is realized outside the device. Two contactors are wired in parallel and a circuit breaker is connected in series. The lock is realized by additional parts, such as an armature and a bearing, which are mounted between the contactor drives and which act on the contact piece carrier. In electric reversing contactors, the lock acts on the armatures of the contactor drives for mutual blocking. That is, the reversing lock for mutual locking of the main drives prevents the simultaneous closing of the main contacts to change the direction of rotation.

Insbesondere soll eine einfache und direkte mechanische Verriegelung eines Hauptschiebers eines Magnetantriebes ermöglicht werden, wenn der andere Magnetantrieb in Betrieb ist.The object of the invention is to provide a magnetic chamber for a low-voltage electromagnetic switching device or a low-voltage electromagnetic switching device, which are very simple and compact and which allows a simple mechanical locking of one of two magnetic drives, while the other magnetic drive is operable. In particular, a simple and direct mechanical locking of a main slide of a magnetic drive is to be made possible when the other magnetic drive is in operation.

Weitere Merkmale und Details der Erfindung ergeben sich aus den Unteransprüchen, der Beschreibung sowie den Zeichnungen. Merkmale und Details die im Zusammenhang mit der Magnetkammer für ein elektromagnetisches Niederspannungsschaltgerät beschrieben sind, gelten dabei selbstverständlich auch im Zusammenhang mit dem elektromagnetischen Niederspannungsschaltgerät und jeweils umgekehrt.These objects are achieved by a magnetic chamber for a low-voltage electromagnetic switching device with the features according to independent claim 1 and by a low-voltage electromagnetic switching device having the features according to
Gemäß dem ersten Aspekt der Erfindung wird die Aufgabe durch eine Magnetkammer für ein elektromagnetisches Niederspannungsschaltgerät, insbesondere einen Kompaktwendestarter, das zwei Magnetantriebe aufweist, wobei jeder Magnetantrieb einen Hauptschieber betätigt, bei der die Magnetkammer zur Aufnahme beider Magnetantriebe des elektromagnetischen Niederspannungsschaltgerätes ausgebildet ist und wobei eine beweglich gehaltene mechanische Wendeverriegelung zur abwechselnden mechanischen Verriegelung eines der beiden Magnetantriebe in der Magnetkammer angeordnet ist, wobei die mechanische Verriegelung auf beide Hauptschieber wirkt, gelöst.According to the first aspect of the invention, the object is achieved by a magnetic chamber for a low-voltage electromagnetic switching device, in particular a Kompaktwendestarter having two magnetic drives, each magnetic drive actuates a main spool, wherein the magnetic chamber for receiving both magnetic drives of the electromagnetic low-voltage switching device is formed and one movable held mechanical Wendeverriegelung for alternating mechanical locking of one of the two magnetic drives is arranged in the magnetic chamber, wherein the mechanical lock acts on both main slide solved.
Kern der Erfindung ist, dass die beweglich gehaltene mechanische Wendeverriegelung direkt in der Magnetkammer angeordnet ist und dass die Magnetkammer zur Aufnahme beider Magnetantriebe ausgebildet ist. Eine derartige Magnetkammer ermöglicht die direkte Verriegelung eines in der Magnetkammer angeordneten Magnetantriebes, insbesondere eines Hauptschiebers eines Magnetantriebes, während der andere Magnetantrieb zum Betrieb freigegeben wird. Je nach Bedarf sperrt die beweglich gehaltene mechanische Wendeverriegelung mal den einen, mal den anderen Magnetantrieb. Die mechanische Wendeverriegelung ist direkt in der Magnetkammer vorgesehen, die sowohl den einen als auch den anderen Magnetantrieb umgibt.The core of the invention is that the movably held mechanical turning lock is arranged directly in the magnet chamber and that the magnet chamber is designed to accommodate both magnet drives. Such a magnetic chamber allows the direct locking of a magnetic drive arranged in the magnetic chamber, in particular a main slide of a magnetic drive, while the other magnetic drive is released for operation. Depending on requirements, the movably held mechanical reversible locking locks the one, sometimes the other magnetic drive. The mechanical turning lock is provided directly in the magnetic chamber, which surrounds both the one and the other magnetic drive.
Dadurch, dass die Magnetkammer beide Magnetantriebe umfasst, kann ein elektromagnetisches Niederspannungsschaltgerät, in dem eine derartige Magnetkammer vorgesehen ist, sehr kompakt ausgebildet werden. Die mechanische Wendeverriegelung kann durch eine derartige Magnetkammer direkt auf einen der Hauptschieber eines der Magnetantriebe, der die Hauptkontakte des Magnetantriebes öffnet und schließt, wirken, d.h. diesen in seiner Bewegung sperren. Dabei funktioniert die Blockierung eines Magnetantriebes dadurch, dass ein Teil der mechanischen Wendeverriegelung in einen Hauptschieber eines Magnetantriebes eingreift und dadurch eine Verschiebung des Hauptschiebers verhindert. Bei dem Eingriff der mechanischen Wendeverriegelung in den Hauptschieber eines der Magnetantriebe, ist der Hauptschieber des anderen Magnetantriebes zur Verschiebung frei gegeben.Characterized in that the magnetic chamber comprises both magnetic drives, a low-voltage electromagnetic switching device, in which such a magnetic chamber is provided, can be made very compact. The mechanical Wendeverriegelung can act through such a magnetic chamber directly on one of the main slide one of the magnetic drives, which opens and closes the main contacts of the magnetic drive, ie lock this in its movement. In this case, the blocking of a magnetic drive functions in that a part of the mechanical turning lock engages in a main slide of a magnetic drive, thereby preventing a displacement of the main slide. When the mechanical turning lock engages the main slide of one of the magnetic drives the main slide of the other magnetic drive is released for movement.
Die beweglich gehaltene mechanische Wendeverriegelung ist in der Magnetkammer angeordnet. D.h., es existiert nur eine gemeinsamen Magnetkammer für beide Magnetantriebe. Zum Verriegeln der Magnetantriebe ist die mechanische Wendeverriegelung daher ebenfalls in der einen Magnetkammer vorgesehen. Dabei sitzt die mechanische Wendeverriegelung vorteilhafterweise zwischen den beiden Magnetantrieben.The movably held mechanical turning lock is arranged in the magnet chamber. That is, there is only one common magnetic chamber for both magnetic drives. For locking the magnetic drives, the mechanical turning lock is therefore also provided in the one magnetic chamber. The mechanical Wendeverriegelung advantageously sits between the two magnetic drives.
Bevorzugt ist eine Magnetkammer, bei der die mechanische Wendeverriegelung als ein um eine Achse verschwenkbar gehaltener Wendeanker ausgebildet ist, wobei die Achse in einer Wandung der Magnetkammer vorgesehen ist. Der Wendeanker, auch als Wendeherz bezeichnet, kann um die Achse gedreht werden, um so wahlweise den einen oder den anderen Magnetantrieb zu blockieren. Die Achse, an der der Wendeanker befestigt ist, ist bevorzugt in der Wandung der Magnetkammer angeordnet. Hierdurch sitzt der Wendeanker direkt an den Magnetantrieben, um diese freizugeben oder zu blockieren. Durch diese Integrierung der Achse bzw. des Wendeankers in die Wandung der Magnetkammer, kann die Magnetkammer und damit das elektromagnetische Niederspannungsschaltgerät, in der die Magnetkammer eingesetzt wird, kompakt aufgebaut werden.Preferred is a magnetic chamber in which the mechanical turning lock is formed as a turning anchor held pivotable about an axis, wherein the axis is provided in a wall of the magnetic chamber. The turning armature, also referred to as a turning heart, can be rotated about the axis, so as to selectively block one or the other magnetic drive. The axis to which the turning armature is attached is preferably arranged in the wall of the magnetic chamber. As a result, the turning armature sits directly on the magnetic drives in order to release or block them. As a result of this integration of the axis or of the turning armature into the wall of the magnet chamber, the magnet chamber and thus the low-voltage electromagnetic switching device in which the magnet chamber is used can be made compact.
Die Magnetkammer ist dabei derart ausgebildet, dass sie die Führung der jeweiligen Hauptschieber und der Magnetantriebe ermöglicht. D.h., die Magnetkammer weist zumindest bereichsweise eine Zwischenwand auf, an deren beiden Wänden die beiden Magnetantriebe, d.h. die Hauptschieber, geführt werden. An dieser Zwischenwand ist die beweglich gehaltene mechanische Wendeverriegelung, insbesondere der Wendeanker, angeordnet.The magnetic chamber is designed such that it allows the guidance of the respective main slide and the magnetic drives. That is, the magnetic chamber has at least partially an intermediate wall, on both walls of which the two magnetic drives, i. the main pushers are guided. At this intermediate wall, the movably held mechanical Wendeverriegelung, in particular the turning armature is arranged.
Gemäß dem zweiten Aspekt der Erfindung wird die Aufgabe durch ein elektromagnetisches Niederspannungsschaltgerät, insbesondere durch einen Kompaktwendestarter, das/der zwei in unterschiedliche Richtungen laufende Magnetantriebe aufweist, wobei jeder Magnetantrieb einen Hauptschieber betätigt, und bei dem beide Magnetantriebe in einer gemäß dem ersten Aspekt der Erfindung ausgebildeten Magnetkammer angeordnet sind, wobei die beweglich gehaltene mechanische Wendeverriegelung je nach ihrer Position mit einem Hauptschieber eines der Magnetantriebe in Eingriff steht, um diesen zu fixieren, gelöst.According to the second aspect of the invention, the object is achieved by a low-voltage electromagnetic switching device, in particular by a Kompaktwendestarter, the / the two in different Magnetically driven directions, wherein each magnetic drive actuates a main slide, and wherein both magnetic drives are arranged in a formed according to the first aspect of the invention, the magnet chamber, wherein the movably held mechanical turning lock, depending on its position with a main slide of one of the magnet drives is engaged, to fix this, solved.
Ein elektromagnetisches Niederspannungsschaltgerät mit einer derartigen Magnetkammer kann sehr kompakt und einfach aufgebaut sein. Durch die Integrierung der beweglich gehaltenen mechanischen Wendeverriegelung in die Magnetkammer wird eine aufwendige Verdrahtung und Befestigung der elektrischen und mechanischen Verriegelung umgangen. Vorteilhafterweise funktioniert die mechanischen Wendeverriegelung auch bei Stromausfall. Durch die direkte Verriegelung der Hauptschieber haben eventuelle Fehler in den Magnetantrieben keinen Einfluss auf die Sicherheitskette. Dadurch, dass die mechanische Wendeverriegelung immer einen der Hauptschieber in seiner Bewegung blockiert, kann es nicht dazu kommen, dass beide Magnetantriebe gleichzeitig betrieben werden können.An electromagnetic low-voltage switching device with such a magnetic chamber can be constructed very compact and simple. By integrating the movably held mechanical turning lock into the magnetic chamber, a complex wiring and fastening of the electrical and mechanical locking is avoided. Advantageously, the mechanical Wendeverriegelung also works in case of power failure. Due to the direct locking of the main slide, any errors in the magnetic drives have no influence on the safety chain. The fact that the mechanical turning lock always blocks one of the main slides in its movement, it can not happen that both magnetic drives can be operated simultaneously.
Besonders bevorzugt ist ein elektromagnetisches Niederspannungsschaltgerät, bei dem jeder Hauptschieber eines jeden Magnetantriebes an seiner zur mechanischen Wendeverriegelung zugewandten Seite eine entsprechend ausgeprägte Kontur, insbesondere eine Nut, eine Vertiefung oder eine Bohrung, zum Eingriff der mechanischen Wendeverriegelung aufweist. Die mechanische Wendeverriegelung greift dabei in die Kontur, beispielsweise in die Nut, die Vertiefung oder die Bohrung, eines Hauptschiebers ein und verhindert so eine Bewegung dieses Hauptschiebers. Besonders vorteilhaft ist es, wenn die mechanische Wendeverriegelung als Wendeanker bzw. Wendeherz ausgebildet ist. Ein Wendeanker bzw. ein Wendeherz hat eine annähernd T-förmige Gestalt. Die Enden des quer angeordneten T-Balkens greifen in die entsprechend ausgeprägten Konturen der jeweiligen Hauptschieber ein.Particularly preferred is a low-voltage electromagnetic switching device, in which each main slide of each magnetic drive on its side facing the mechanical turning lock side has a correspondingly pronounced contour, in particular a groove, a recess or a bore, for engaging the mechanical Wendeverriegelung. The mechanical turning lock engages in the contour, for example in the groove, the recess or the bore, a main slide and thus prevents movement of this main slide. It is particularly advantageous if the mechanical turning lock is designed as a turning anchor or turning heart. A turning anchor or a turning heart has an approximately T-shaped form. The ends of the transversely arranged T-bar engage in the correspondingly pronounced contours of the respective main slide.
Vorzugsweise weist das elektromagnetische Niederspannungsschaltgerät einen Mikrokontroller zur Ansteuerung der Antriebseinheiten der Magnetantriebe bzw. der Wendeverriegelung auf. D.h., die elektrische Ansteuerung der Wendeverriegelung kann durch den gleichen Mikrokontroller realisiert werden, der auch für die Ansteuerung beider Magnetantriebe ausgebildet ist. Die Ansteuerung der Wendeverriegelung erfolgt insbesondere über die Magnetantriebe. Hierdurch kann wiederum Hardware eingespart werden und das elektromagnetische Niederspannungsschaltgerät klein dimensioniert werden.Preferably, the electromagnetic low-voltage switching device has a microcontroller for controlling the drive units of the magnetic drives or the turning lock. That is, the electrical control of the turning lock can be realized by the same microcontroller, which is also designed for driving both magnetic drives. The control of the reversible locking takes place in particular via the magnetic drives. This in turn allows hardware to be saved and the low-voltage electromagnetic switching device to be dimensioned small.
Des Weiteren ist ein elektromagnetisches Niederspannungsschaltgerät bevorzugt, bei dem die Magnetantriebe als Schützantriebe ausgebildet sind. Die Wendeverriegelung zur gegenseitigen Blockierung der Schützantriebe verhindert die gleichzeitige Schließung der Hauptkontakte zur Drehrichtungsänderung der Schützantriebe. Die technische Lösung ist durch den Wendeanker bzw. das Wendeherz realisiert, der/das die Hauptschieber der jeweiligen Schützantriebe zur Schließung der Kontakte blockiert. Die Wirkung des Wendeankers ist direkt auf die Hauptschieber, die die Hauptkontakte der jeweiligen Schützantriebe öffnen und schließen.Furthermore, a low-voltage electromagnetic switching device is preferred in which the magnetic drives are designed as contactor drives. The reversible locking mechanism for mutual blocking of the contactor drives prevents the simultaneous closure of the main contacts to change the direction of rotation of the contactor drives. The technical solution is realized by the turning armature or the turning heart, which blocks the main slide of the respective contactor drives to close the contacts. The effect of the turning armature is directly on the main slide, which open and close the main contacts of the respective contactor drives.
