Description

Die Erfindung betrifft einen Niederspannungs-Leistungsschalter mit einem nachrüstbaren Motoraufzug, dessen Ausgangswelle mit einer in einem Lagerblock gelagerten Spannwelle des Federspeichers des Niederspannungs-Leistungsschalters koppelbar ist.The invention relates to a low-voltage circuit breaker with a retrofittable motor elevator, the Output shaft with one in a bearing block Spring shaft of the low-voltage circuit breaker can be coupled.

Niederspannungs-Leistungsschalter weisen als Grundausstattung im allgemeinen einen Handantrieb auf, bei dem mit einer bestimmten vorgegebenen Anzahl von Bewegungshüben ein Federspeicher gespannt wird. Der Zustand "gespannt" des Federspeichers wird dann angezeigt, und der Schalter ist einschaltbereit, wenn die anderen Verriegelungsbedingungen wie "Tür geschlossen", "Kurbel des Fahrantriebs abgezogen", und dergleichen, erfüllt sind.Low voltage circuit breakers have basic equipment generally a manual drive, in which with a a certain predetermined number of movement strokes Spring loaded. The state "tense" of the Spring memory is then displayed and the switch is on ready to switch on if the other locking conditions such as "door closed", "crank of the drive mechanism removed", and the like are satisfied.

Für höhere Management- oder Komfortansprüche gibt es dann zusätzlich den Motoraufzug. Weil der Handaufzug die Grundausführung und der Motoraufzug eine zusätzliche Ausstattung ist, wird der Motoraufzug so ausgebildet, daß er eine nachrüstbare Einheit bildet. Dabei soll die Nachrüstbarkeit auch bei Schaltern möglich sein, die bereits in einer Schaltanlage eingebaut sind. Das soll ohne großen Aufwand möglich sein.Then there is for higher management or comfort requirements additionally the motor elevator. Because the manual winding is the basic version and the motor elevator additional equipment is, the motorized elevator is designed so that it is a retrofittable unit forms. The retrofit is supposed to be also be possible with switches that are already in one Switchgear are installed. That should be done without much effort to be possible.

Die Motoraufzugseinheit besteht in der Regel aus einem Gehäuse in dem sich ein Getriebemotor befindet, dessen Getriebe ein großes Untersetzungsverhältnis aufweist und dessen Ausgangswelle mit der Spannwelle des Federspeichers des Niederspannung-Leistungsschalters gekoppelt ist, auf die auch der Handaufzug wirkt. The motor winding unit usually consists of one Housing in which there is a geared motor, the Gearbox has a large reduction ratio and whose output shaft with the tension shaft of the spring accumulator of the low-voltage circuit breaker is coupled to the the manual wind also works.

Die US-PS 4 901 821 zeigt, insbesondere in der Fig.3, die Befestigung einer Motor-Getriebeeinheit für den Aufzug des Federspeichers eines Niederspannungs-Leistungsschalters, bei dem diese Motor-Getriebeeinheit mittels Schrauben an einer Tragplatte befestigt ist. Das bedingt den Zugang zu den Schrauben von einer Seite der Tragplatte und Platz zum Ansetzen der Motor-Getriebeeinheit von der anderen Seite derselben. Eine nachträgliche Montage der Motor-Getriebeeinheit bei einem in einer Schaltanlage eingebauten Niederspannungs-Leistungsschalter ist bei dieser Ausführung nicht möglich.US Pat. No. 4,901,821 shows, in particular in FIG Attachment of a motor-gear unit for the elevator of the Spring accumulator of a low-voltage circuit breaker, at which this motor gear unit by means of screws on one Support plate is attached. That requires access to the Screw from one side of the support plate and space to Position the motor-gear unit from the other side the same. A subsequent assembly of the motor-gear unit in a switchgear installed Low voltage circuit breaker is in this version not possible.

Auch eine in der US-PS 4 649 244 beschriebene Motor-Getriebeeinheit zum Aufzug eines Energiespeichers zum Abschalten eines Niederspannungs-Leistungsschalters ist nicht für einen nachträglichen Einbau von vorn in einen in einer Schaltanlage befindlichen Schalter geeignet. Alle bisherigen Ausführungen von Motoraufzügen zum Spannen von Federspeichern bei Niederspannungs-Leistungsschaltern gestattet nur eine Montage von der Seite des Niederspannungs-Leistungsschalters, also nur bei nicht in einer Schaltanlage eingebauten Schaltern. Somit ist eine problemlose Nachrüstung derartiger Schalter in einer Schaltanlage nicht möglich.Also a motor-transmission unit described in US Pat. No. 4,649,244 to lift an energy store to Switching off a low voltage circuit breaker is not for retrofitting from the front into one in one Switchgear located switch suitable. All previous ones Versions of motor lifts for tensioning spring accumulators only one is permitted for low-voltage circuit breakers Assembly from the side of the low-voltage circuit breaker, So only when not installed in a switchgear Switches. This makes retrofitting easy Switch in a switchgear is not possible.

Die Aufgabe der vorliegenden Erfindung besteht folglich darin, eine Befestigung für Motoraufzüge zu schaffen, die eine Montage derselben von der Frontseite des Niederspannungs-Leistungsschalters und somit eine Nachrüstung derartiger Schalter einer eingebauten Position ermöglicht.The object of the present invention is therefore in creating an attachment for motor lifts that mounting them from the front of the low-voltage circuit breaker and therefore a retrofit Such switch allows a built-in position.

Zur Lösung diese Aufgabe werden erfindungsgemäß an einem Flansch des Lagerblocks der Spannwelle des Federspeichers Zentrierelemente zum Eingriff in Gegenelemente am Getriebeausgang des Motoraufzugs vorgesehen, in die der Motoraufzug mit einem geringen Weg axial in Richtung der Spannwelle einschiebbar ist. Der geringe erforderliche axiale Weg beim Einschieben des Motoraufzugs in die Zentrierelemente ermöglicht bei einer gewünschten Nachrüstung eine nachträgliche Montage des Motoraufzugs bei einem in einer Schaltanlage eingebauten Schalter von der Vorderseite. Der Motoraufzug ist in diesen Zentrierelementen schwenkbar und das Einschieben in diese Zentrierelemente erfolgt in einer im Schalter in die Richtung zur Frontseite des Schalters geschwenkten Stellung. Gleichzeitig wird dabei auch die Kupplung zwischen dem Getriebeausgang und der Spannwelle des Federaufzugs hergestellt. Weiterhin ist zur Arretierung des Motoraufzugs in der Schwenkrichtung an einer von der Zentrierung in einer gewissen Entfernung angebrachten Stelle ein Befestigungsmittel vorgesehen. Darüber hinaus sind Mittel für eine axiale Fixierung des Motoraufzugs in den Zentrierelementen des Flansches des Lagerblocks der Spannwelle des Federaufzugs und in der Kupplung der Spannwelle vorhanden.To solve this problem, according to the invention, on one Flange of the bearing block of the spring shaft tension shaft Centering elements for engaging mating elements at the gearbox output of the motorized elevator into which the motorized elevator with a small axial path in the direction of the tension shaft can be inserted. The small axial path required for The motor elevator can be pushed into the centering elements if a retrofit is required, a subsequent one Installation of the motor elevator in a switchgear built-in switch from the front. The motor elevator is pivotable in these centering elements and the insertion in this centering takes place in a switch in the Direction to the front of the switch pivoted position. At the same time, the clutch between the Gearbox output and the spring shaft tension shaft. Furthermore, for locking the motor elevator in the swivel direction on one of the centering in one a fastener at a certain distance intended. In addition, there are means for an axial Fixing the motor elevator in the centering elements of the Flange of the bearing block of the tension shaft of the spring winding and present in the coupling of the tension shaft.

Es bleiben folglich einige Merkmale des herkömmlichen Motoraufzugs erhalten, insbesondere die Stirnverzahnung der miteinander zu kuppelnden Wellen und die gefederte Andruckvorrichtung für den Wellenstumpf des Motoraufzugs. Das Befestigungsmittel zur Arretierung des Motoraufzugs in der Schwenkrichtung kann vorteilhaft aus einem Rastelement am Motor/Getriebeblock des Motoraufzugs und einer in den Isolierteilen am Schalterrahmen angeordneten Federrastung bestehen. Es kann aber auch durch eine Öse am Motor/Getriebeblock des Motoraufzugs, eine Gewindebohrung in einem Anschlag und eine durch die Öse in die Gewindebohrung einschraubbaren Schraube gebildet werden. Wesentlich ist in jedem Fall eine Handhabung in der Montagerichtung des Motoraufzugs, also von der Frontseite des Niederspannungs-Leistungsschalters.Consequently, some features of the conventional one remain Get motor elevator, especially the spur gear teeth shafts to be coupled together and the spring-loaded pressure device for the stub shaft of the motor elevator. The Fastening device for locking the motor elevator in the Swivel direction can advantageously be from a locking element on Motor / gear block of the motor elevator and one in the Insulating parts on the switch frame arranged spring catch consist. But it can also be through an eyelet on the engine / gear block of the motor elevator, one threaded hole in one Stop and one through the eyelet into the threaded hole screw-in screw are formed. Is essential in any handling in the mounting direction of the Motor elevator, i.e. from the front of the low-voltage circuit breaker.

Das Mittel zur axialen Fixierung des Motoraufzugs in den Zentrierelementen des Flansches des Lagerblocks der Spannwelle des Federaufzugs und in der Kupplung der Spannwelle ist vorteilhaft ein am Lagerblock der Spannwelle des Federaufzugs angebrachter starrer Stützarm, der einen angeformten Winkel aufweist.The means for axially fixing the motor elevator in the Centering elements of the flange of the bearing block of the tension shaft of the spring winding and in the coupling of the tension shaft advantageous on the bearing block of the tension shaft of the spring elevator attached rigid support arm that has a molded angle having.

In einer alternativen Ausführung kann das Mittel zur axialen Fixierung des Motoraufzugs in den Zentrierelementen des Flansches des Lagerblocks der Spannwelle des Federaufzugs und in der Kupplung der Spannwelle auch ein mit Haken in Löchern im Lagerblock der Spannwelle des Federspeichers befestigter federnder Drahtbügel sein, der den Motoraufzug umfaßt, und in dafür vorgesehenen Rastelementen am Motoraufzug arretierbar ist. Vor dem Einbau des Motoraufzugs wird dieser Drahtbügel mittels der Löcher montiert. Die hakenartigen Enden des Drahtbügels und die Löcher sind so dimensioniert, daß der Drahtbügel nach unten hängen kann und das Einsetzen des Motoraufzugs nicht behindert. Er ist ferner so bemessen, daß er den Motoraufzug umfaßt. Die Endlage des Motoraufzugs ist durch geeignete Anschläge definiert und in dieser Endlage ist der Drahtbügel von unten über den Motoraufzug hochziehbar und in dafür vorgesehenen Rastelementen arretierbar.In an alternative embodiment, the means for axial Fixing the motor elevator in the centering elements of the Flange of the bearing block of the tension shaft of the spring winding and in the coupling of the tension shaft also one with hooks in holes attached in the bearing block of the tensioning shaft of the spring accumulator resilient wire bracket that includes the motor elevator, and in Locking elements provided for this purpose can be locked on the motor elevator is. Before installing the motor elevator, this wire bracket mounted by means of the holes. The hooked ends of the Wire bracket and the holes are dimensioned so that the Wire hanger can hang down and inserting the Motor elevator not hindered. It is also such that he includes the motor elevator. The end position of the motor elevator is defined by suitable stops and is in this end position the wire bracket can be pulled up from below via the motor elevator and can be locked in the locking elements provided.

Ein derartiger Drahtbügel zur Befestigung eines Bauelementes, hier einer Löschkammer für ein elektrisches Schaltgerät, mittels einer federnden Drahtklammer, ist an sich in der DE-OS 1 908 751 beschrieben. Eine gleichartige Befestigung ist zur Fixierung von Verteilerkappen bei Zündverteilern von Kraftfahrzeugen allgemein bekannt. Sie dienen in allen bekannten Fällen jedoch lediglich zur Fixierung passiver Elemente, die keinen wesentlichen mechanischen Beanspruchungen ausgesetzt sind. Der Vorteil des Drahtbügels im vorliegenden Anwendungsfall besteht darin, daß er nicht grundsätzlich eingebaut werden muß, wie der starre Stützarm, egal ob er einmal benötigt wird, oder nicht. Er ist auch billiger und kann mit dem Motoraufzug mitgeliefert werden. Es kann natürlich auch eine Kombination beider Befestigungen verwendet werden.Such a wire bracket for fastening a component, here an arcing chamber for an electrical switching device, by means of a resilient wire clip, is in itself in the DE-OS 1 908 751. A similar attachment is used to fix distributor caps on ignition distributors from Motor vehicles generally known. They serve in all known cases, however, only for passive fixation Items that do not have significant mechanical stress are exposed. The advantage of the wire bracket in present use case is that it is not must always be installed, like the rigid support arm, no matter if it is needed or not. He's also cheaper and can be supplied with the motorized elevator. It can of course also be a combination of both fastenings be used.
