Abstract

The remote drive is to be connected to the side of the protective switch as a module. The module acts on the actuating mechanism of the protective switch by means of two sliders. These are actuated directly by a current pulse driven magnet drive via a spring biased lever (22). The remote drive (4) has a base unit (6) to be laterally connected to the switch. It also has an extension (8) at least partly covering the switch. The base unit (6) contains the magnet drive (16) and a transmission mechanism (22,26). The latter is acted on by the magnet drive (16) and contains the spring biased lever (22). The extension (8) contains a drive mechanism including the sliders (28,30). The drive mechanism is connected to the transmission mechanism via one of at least two coupling elements (36,38) and is connected to the drive shaft (32) of the actuating mechanism via the sliders. The extension (8) can be mounted on the base unit (6) at least two positions which are offset from each other by the component width of at least one further module between the base unit and the switch. The identical coupling elements are spaced from each other by a corresponding distance.

Die Erfindung betrifft einen Fernantrieb für Niederspannungs-Schutzschalter nach dem Oberbegriff des Anspruches 1. Insbesondere betrifft die Erfindung einen Fernantrieb für Motorschutzschalter.The invention relates to a remote operator for low-voltage circuit breakers according to the preamble of claim 1. In particular The invention relates to a remote drive for motor protection switches.

Aus der DE-A-34 41 550 ist ein derartiger Fernantrieb bekannt, der als Modul seitlich mit dem Schutzschalter zu verbinden ist, und mittels zweier von einem stromimpulsbetriebenen Magnetantrieb über einen federvorbelasteten Hebel mittelbar betätigter Stößel auf den Betätigungsmechanismus des Schutzschalters wirkt. Der Nachteil dieses Standes der Technik besteht darin, daß zwischen Fernantrieb und Schutzschalter kein weiteres Modul, beispielsweise ein Unterspannungsauslöser, angeordnet werden kann, denn dazu wäre ein anderer Fernantrieb vorzusehen, dessen Betätigungsstößel an den veränderten Abstand zum Schutzschalter angepaßt sein und ungünstigerweise durch das weitere Modul reichen muß.Such a remote drive is known from DE-A-34 41 550, which is to be connected as a module to the side of the circuit breaker, and by means of two of a current pulse operated magnetic drive indirectly operated via a spring-loaded lever Tappet on the operating mechanism of the circuit breaker works. The disadvantage of this prior art is that that no further between remote operator and circuit breaker Module, for example an undervoltage release, arranged because another remote drive would have to be provided the actuating plunger to the changed distance to Circuit breaker must be adapted and unfavorably by that additional module must be sufficient.

Der Erfindung liegt daher die Aufgabe zugrunde, einen gattungsgemäßen Fernantrieb zu schaffen, der in einfacher Weise die Möglichkeit zuläßt, zwischen diesem und dem Schutzschalter ein weiteres Modul anzuordnen.The invention is therefore based on the object, a generic To create remote control that easily Possibility allows between this and the circuit breaker arrange another module.

Ausgehend von einem Fernantrieb der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Der Fernantrieb ist in eine seitliche Grundeinheit und einen vorderseitigen Aufsatz mit wenigstens zwei versetzten Koppelelementen modular aufgeteilt, wodurch er in verschiedenen, d.h. versetzten Positionen auf die Grundeinheit aufzubauen ist. Der Fernantrieb ist in einfacher Weise an den Schutzschalter in der Art anbaubar, daß entweder Grundeinheit und Schutzschalter unmittelbar oder mittelbar unter Zwischenbau wenigstens eines weiteren Moduls, beispielsweise eines Unterspannungsauslösers, verbunden sind. Der Aufsatz überdeckt dabei im wesentlichen die Frontseite des Schutzschalters und im gegebenen Falle vollständig die weiteren Module.Starting from a remote drive of the type mentioned the task according to the invention by the characteristic features of claim 1 solved. The remote operator is in a side Basic unit and a front attachment with at least two staggered coupling elements modularly divided, making it in different, i.e. moved positions on the base unit is to be built. The remote operator is on in a simple manner the circuit breaker can be attached in such a way that either basic unit and circuit breaker directly or indirectly under intermediate at least one further module, for example one Undervoltage release are connected. The essay covers essentially the front of the circuit breaker and if necessary, complete the other modules.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. In zweckmäßiger Weise enthalten die Antriebsmittel einen federnden Hebel und einen Schieber mit einem Mitnehmer, der je nach Bedarf in eines der zueinander versetzten, als Eingriffsöffnungen ausgestalteten Koppelelemente eingreift, wobei jede dieser Eingriffspositionen einem definierten seitlichen Abstand zwischen Grundeinheit und Schutzschalter entspricht. Durch den federnd ausgestalteten Hebel werden die relativ hohen Antriebskräfte, die beim ruckartigen Anziehen des Ankers entstehen, erheblich reduziert, wodurch sich ein geringerer Verschleiß bzw. eine höhere Lebensdauer der mechanischen Antriebsteile und damit letztendlich des Fernantriebes ergibt. Die Ausführung der Antriebsmittel in Form von mit Zahnstangen versehenen Stößeln, die wechselweise durch Einwirkung eines Umschalthebels angetrieben werden und mit einem Ritzel in Eingriff stehen, das direkt mit der Antriebswelle des Schutzschalters verbunden ist, ist zweckmäßig für drehbetätigte Schutzschalter. Mit einer durch den Aufsatz hindurch gehenden Antriebswelle läßt sich zusätzlich und nach Bedarf ein Betätigungsknebel für die Handbedienung des Schutzschalters anbringen.Further advantageous embodiments of the invention are the See subclaims. Conveniently included the drive means with a resilient lever and a slide a driver who moves into one of the other as required offset coupling elements designed as engagement openings engages, each of these engagement positions one defined lateral distance between base unit and Circuit breaker corresponds. Due to the springy design Levers are the relatively high driving forces that occur with jerky Tightening of the anchor arise, significantly reduced, which results in less wear and a longer service life of the mechanical drive parts and thus ultimately of the remote drive results. The execution of the drive means in Form of toothed rams alternately are driven by the action of a switching lever and mesh with a pinion that directly with the Drive shaft of the circuit breaker is connected is appropriate for rotary operated circuit breakers. With one through the essay drive shaft passing through can additionally and after Requires an actuation toggle for manual operation of the circuit breaker attach.

Der Aufsatz 8 beinhaltet Antriebsmittel, die einerseits über eines von zwei Koppelelementen mit den Übertragungsmitteln der Grundeinheit 6 und anderseits über Stößel 28, 30 mit einer Antriebswelle 32 des Betätigungsmechanismus des Schutzschalters verbunden sind. Dazu reicht der Schieber 26 mit einen Mitnehmer 34 aus der Grundeinheit 6 in den Aufsatz 8 hinein und steht wahlweise mit einem der als Eingriffsöffnungen ausgestalteten zwei Koppelelemente 36, 38 in Verbindung. Die gleichartigen Koppelelemente 36, 38 sind wiederum um den Abstand B gegeneinander versetzt angeordnet, wodurch der Aufsatz 8 wahlweise in den zwei, um den Abstand B versetzten Positionen auf der Grundeinheit 6 montierbar ist, indem der Mitnehmer 34 entweder in das erste oder in das zweite Koppelelement 36 bzw. 38 eingreift. Die Antriebsmittel bestehen aus einem die Koppelelemente 36, 38 enthaltenden Träger 40, einem in diesem um eine Schwenkachse 50 gelagerten Umschalthebel 42 sowie den von diesem in bekannter Weise wechselweise antreibbaren und endseitig mit Zahnstangen 44 bzw. 46 versehenen Stößeln 28 und 30, die mit einem drehfest mit der Antriebswelle 32 verbundenen Ritzel 48 kämmen. Die Antriebswelle 32 reicht durch den Aufsatz 8 und ist endseitig mit dem Betätigungsknebel 14 verbunden.According to FIGS. 3 and 4, the basic unit 6 contains one current pulse-driven magnetic drive 16 and operatively connected to it Means of transmission. The means of transfer exist from an armature 18 of the magnetic drive 16, mounted in a stationary lever axis 20, two-armed resilient lever 22 and from one of these against the action a return spring 24 loaded slide 26. The essay 8 includes drive means, on the one hand over one of two Coupling elements with the transmission means of the basic unit 6 and on the other hand via plungers 28, 30 with a drive shaft 32 of the operating mechanism of the circuit breaker are connected. For this purpose, the slide 26 extends with a driver 34 from the Base unit 6 into the attachment 8 and is optionally available one of the two coupling elements designed as engagement openings 36, 38 in connection.
