Description

Die Erfindung betrifft einen Leistungsschalter, insbesondere für Niederspannungen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a circuit breaker, in particular for low voltages, according to the preamble of claim 1.

Aus der Offenlegungsschrift DE 195 07 604 A1 ist ein elektrischer Hauptschalter mit einer Verriegelungsvorrichtung bekannt. Diese Verriegelungsvorrichtung weist ein drehbares Sperrteil mit einem Exzenternocken und einen mit dem Nocken in Eingriff befindlichen Sperrschieber zur Blockierung des Schaltwerks des Schalters auf.From the publication DE 195 07 604 A1 is a main electrical switch with a locking device known. This locking device comprises a rotatable locking member with an eccentric cam and a locking cam engaged with the cam for locking the derailleur of the switch.

Weiterhin ist bekannt, Leistungsschalter für Niederspannungen mittels eines Zylinderschlosses in einem Schaltzustand zu verriegeln (bzw. abzuschließen). Zum Nachrüsten eines Leistungsschalters werden das Zylinderschloss und die zugehörige Mechanik direkt in den Zubehördeckel des Gehäuses geschraubt. Dabei kann eine Vielzahl von Fehlern auftreten. So ist zum Einbau ein Durchbruch im Zubehördeckel erforderlich, der vom Anwender ausgebrochen werden muss, was leicht zu einem Versatz führen kann, weil die Schnittstelle dabei nicht eindeutig definiert ist. Weiter ist das Nachrüsten von zusätzlichem Zubehör bei verriegeltem Leistungsschalter nicht möglich, ohne den Leistungsschalter zu entriegeln, da der Zubehördeckel nur in entriegeltem Zustand demontierbar ist. Ferner ist bei einschraubbaren Zylinderschlössern (oder Zylinderschlosseinheiten) optisch meist nicht erkennbar, ob der Leistungsschalter verriegelt ist oder nicht.Furthermore, it is known to lock circuit breakers for low voltages by means of a cylinder lock in a switching state (or complete). To retrofit a circuit breaker, the cylinder lock and the associated mechanism are screwed directly into the accessory cover of the housing. This can lead to a variety of errors. For example, a break-through in the accessory cover is required for installation, which must be broken open by the user, which can easily lead to an offset because the interface is not clearly defined. Furthermore, it is not possible to retrofit additional accessories when the circuit-breaker is locked without unlocking the circuit-breaker, as the accessory cover can only be removed when it is unlocked. Furthermore, in the case of screw-in cylinder locks (or cylinder lock units), it is usually not visually discernible whether the circuit breaker is locked or not.

Die Aufgabe der Erfindung ist es, eine Verriegelungseinheit für einen Leistungsschalter vorzuschlagen, der mit geringem Aufwand und ohne Werkzeug nachrüstbar ist.The object of the invention is to propose a locking unit for a circuit breaker, which can be retrofitted with little effort and without tools.

Die Aufgabe der Erfindung wird durch die Merkmale des Anspruchs 1 gelöst; die Unteransprüche stellen vorteilhafte Ausgestaltungen dar.The object of the invention is solved by the features of claim 1; the dependent claims represent advantageous embodiments.

Die Lösung sieht vor, dass die Verriegelung als Verriegelungseinheit ausgebildet und in eine Ausnehmung des Gehäuses eingesetzt ist, die sich neben der Handhabe befindet, dass die Ausnehmung und die Handhabe über eine Durchgangsöffnung miteinander verbunden sind, und dass die Verriegelungseinheit einen Schieber aufweist, der beim Verriegeln durch die Durchgangsöffnung hindurch in den Bereich der Handhabe geschoben wird und sich soweit in diesen Bereich hineinerstreckt, dass er das Verschwenken der Handhabe blockiert. Es ist also lediglich notwendig, einen Ausbruch im Zubehördeckel zu schaffen und anschließend die Verriegelungseinheit ohne Werkzeug in die Ausnehmung einzusetzen. Die Verriegelungseinheit kann vormontiert werden, so dass ein Nachrüsten eines Leistungsschalters deutlich vereinfacht wird, da man die Verriegelungseinheit wie internes Zubehör nach Art einer Komplettbaugruppe nachrüstet. Da die Verriegelung als Einheit ausgebildet ist, spielt es keine Rolle, wie der Durchbruch durch den Zubehördeckel gestaltet ist. Die Verriegelungsschnittstelle ist unabhängig von der Qualität des Durchbruchs definiert. Eine solche Verriegelungseinheit kann bei verschiedenen Schaltergrößen zum Einsatz kommen. Da die Verriegelungseinheit in einer Ausnehmung nach Art einer Zubehörtasche befestigt ist, ist auch bei verriegeltem bzw. abgeschlossenem Leistungsschalter internes Zubehör nachrüstbar. Dazu muss der Leistungsschalter nicht entriegelt werden. Außerhalb des Leistungsschalters ist erkennbar, in welchem Schaltzustand sich die Verriegelungseinheit befindet, da auf dem Verriegelungsstumpf der Verriegelungseinheit genug Platz für die Beschriftungen ist.The solution provides that the lock is formed as a locking unit and is inserted into a recess of the housing, which is located next to the handle, that the recess and the handle are connected to each other via a through hole, and that the locking unit comprises a slide, the Locking through the passage opening is pushed into the region of the handle and hineinerstreckt so far in this area that it blocks the pivoting of the handle. So it is only necessary to create an eruption in the accessory cover and then insert the locking unit without tools in the recess. The locking unit can be preassembled, so that a retrofit of a circuit breaker is significantly simplified because you retrofitted the locking unit like internal accessories in the manner of a complete assembly. Since the lock is formed as a unit, it does not matter how the breakthrough is made by the accessory cover. The locking interface is defined independently of the quality of the breakthrough. Such a locking unit can be used with different switch sizes. Since the locking unit is mounted in a recess in the manner of an accessory bag, internal accessories can be retrofitted even if the circuit breaker is locked or closed. For this purpose, the circuit breaker does not need to be unlocked. Outside the circuit breaker can be seen in which switching state is the locking unit, as on the locking stump of the locking unit is enough space for the labels.

Technisch einfach ist es, wenn die Verriegelung in ihrer Schließstellung das Verschwenken der Handhabe aus der Aus-Stellung in die Ein-Stellung blockiert.It is technically simple when the lock in its closed position blocks the pivoting of the handle from the off position to the on position.

Bei einer einfachen Ausführung erfolgt das Verschwenken der Handhabe mittels eines Verschwenkmechanismus, der eine Blockieröffnung aufweist, in welche das Schiebeelement geschoben wird, um ein Verschwenken der Handhabe zu blockieren.In a simple embodiment, the pivoting of the handle by means of a pivoting mechanism having a blocking opening, in which the sliding element is pushed to block a pivoting of the handle takes place.

Im einfachsten Falle ist die Verriegelungseinheit als Zylinderschlosseinheit ausgebildet.In the simplest case, the locking unit is designed as a cylinder lock unit.

Der Einbau ohne Werkzeug wird erleichtert, wenn die Verriegelungseinheit beim Einsetzen im Gehäuse verrastet.Installation without tools is facilitated if the locking unit latches when inserted in the housing.

Fig. 1 zeigt einen Leistungsschalter für Niederspannungen (im Folgenden kurz Schalter 1 genannt), der ein Gehäuse 2 mit einer Abdeckung 2a aufweist, aus der eine Handhabe 3 in Form eines Schwenkhebels 3a herausragt. Der Schwenkhebel 3a ist manuell aus einer Ein-Stellung in eine Aus-Stellung verschwenkbar und zeigt durch seine jeweilige Hebel-Stellung an, ob der Leistungsschalter 1 ein- oder ausgeschaltet ist. Mittels des Schwenkhebels 3a können nicht gezeigte Schaltkontakte geöffnet und geschlossen werden, über die der elektrische Strom durch den Schalter 1 fließt. Fig. 1 shows a circuit breaker for low voltages (hereinafter referred to briefly as switch 1), which has a housing 2 with a cover 2a, from which a handle 3 in the form of a pivot lever 3a protrudes. The pivot lever 3a is manually pivotable from an on position to an off position and indicates by its respective lever position, whether the circuit breaker 1 is on or off. By means of the pivot lever 3a, switch contacts, not shown, can be opened and closed, via which the electrical current flows through the switch 1.

Neben dem Schwenkhebel 3a befindet sich eine Verriegelung 4 in Form eines Zylinderschlosses 4a, welches in seiner Schließstellung das Einschalten des Schalters 1 blockiert. Der Schwenkhebel 3a und das Zylinderschloss 4a erstrecken sich durch die Abdeckung 2a hindurch nach außen und sind so für eine Bedienperson zugänglich.In addition to the pivot lever 3a is a lock 4 in the form of a cylinder lock 4a, which blocks the switching of the switch 1 in its closed position. The pivoting lever 3a and the cylinder lock 4a extend outwardly through the cover 2a and are thus accessible to an operator.

In Fig. 2 ist der Schalter 1 gemäß Fig. 1 teilweise aufgeschnitten gezeigt, und zwar mit Blick auf das Zylinderschloss 4a, der zu einer Zylinderschlosseinheit 6a (Verriegelungseinheit 6) gehört, die das Zylinderschloss 4a mit umfasst. Die Zylinderschlosseinheit 6a ist in eine entsprechende Ausnehmung 6b des Gehäuses 2 verrastend eingesetzt, unmittelbar neben dem Schwenkhebel 3a, getrennt von einer inneren Gehäusewand 7. Mit Hilfe des Zylinderschlosses 4a wird ein Schieber 7a verschoben, um den Schalter 1 zu verriegeln.In Fig. 2 is the switch 1 according to Fig. 1 shown partially cut away, with a view of the cylinder lock 4a, which belongs to a cylinder lock unit 6a (locking unit 6), which includes the cylinder lock 4a with. The cylinder lock unit 6a is latchingly inserted into a corresponding recess 6b of the housing 2, immediately adjacent to the pivot lever 3a, separated from an inner housing wall 7. With the help of the cylinder lock 4a, a slide 7a is moved to lock the switch 1.

Fig. 3 zeigt den Schalter gemäß Fig. 2 ohne die Zylinderschlosseinheit 6a, wodurch die Ausnehmung 6b und eine Durchgangsöffnung 8 in der inneren Gehäusewand 7 besser zu sehen sind. Fig. 3 shows the switch according to Fig. 2 without the cylinder lock unit 6a, whereby the recess 6b and a passage opening 8 in the inner housing wall 7 can be seen better.

In Fig. 4 ist die separat einsetzbare Zylinderschlosseinheit 6a mit dem Schieber 7a gezeigt. Man erkennt, dass der Schieber 7a mittels eines radialen Hebels 9 des Zylinderschlosses 4a verschiebbar ist.In Fig. 4 is the separately usable cylinder lock unit 6a shown with the slide 7a. It can be seen that the slide 7a is displaceable by means of a radial lever 9 of the cylinder lock 4a.

In Fig. 5 ist der Schieber 7a zu sehen, wie er sich durch die Durchgangsöffnung 8 hindurch in den Bereich des Schwenkhebels 3a erstreckt, der in Fig. 5 durch die Schnittdarstellung nur noch als Streifen 3b zu sehen ist und den Schalter 1 über einen Schwenkmechanismus 10 ein- und ausschaltet. Zum Schwenkmechanismus 10 gehören zwei Seitenplatten 11, die im Gehäuse 2 um eine Drehachse 12 schwenkbar gelagert sind und von denen die eine Seitenplatten 11 in Fig. 5 von dem Schieber 7a blockiert ist.In Fig. 5 the slider 7a can be seen as it extends through the passage opening 8 in the region of the pivot lever 3a, which in Fig. 5 can only be seen as a strip 3b through the sectional view and the switch 1 via a pivot mechanism 10 on and off. The pivot mechanism 10 includes two side plates 11, which are in the housing 2 are pivotally mounted about an axis of rotation 12 and of which the one side plates 11 in Fig. 5 is blocked by the slide 7a.

Alternativ kann der Schalter 1 mittels der abgeschlossenen Zylinderschlosseinheit 6a in seiner Ein-Stellung blockiert werden, wenn der Hebel 9 bezogen auf Fig.4 um 180° nach hinten gedreht wird und die Durchgangsöffnung 8 entsprechend verschoben angeordnet ist. (Möglich ist es selbstverständlich auch, für den Schieber 7a eine zweite Durchgangsöffnung vorzusehen.) Wahlweise ist dann jeweils eine der beiden Alternativen, also die Blockierung der Aus-Stellung oder der Ein-Stellung, realisierbar. Dies wäre dann durch einen einfachen Umbau möglich. Bei blockierter Ein-Stellung und einer Auslösung schalten die Schaltkontakte trotzdem, es geht bei dieser Alternative nur darum, zu verhindern, dass jemand den Schalter 1 an der Handhabe 3 ausschaltet.Alternatively, the switch 1 can be blocked by means of the closed cylinder lock unit 6a in its on position when the lever 9 relative to Figure 4 is rotated by 180 ° to the rear and the passage opening 8 is arranged displaced accordingly. (It is of course also possible to provide a second passage opening for the slide 7a.) Optionally, one of the two alternatives, ie the blocking of the off position or the on position, can then be implemented in each case. This would be possible by a simple conversion. With blocked on-position and a trigger switch contacts switch anyway, it is in this alternative only to prevent someone off the switch 1 on the handle 3.

Die Zylinderschlosseinheiten 6a können zum Verriegeln und zum Abschließen des Schalters 1 verwendet werden. Abschließen bedeutet, dass jede Zylinderschlosseinheit 6a einen eigenen Schlüssel besitzt, der in der Abgeschlossen-Schlüsselstellung (Schalter AUS) und in der Nicht-Abgeschlossen-Schlüsselstellung (Schalter EIN) abgezogen werden kann. Verriegeln bedeutet, dass beispielsweise zwei Schalter 1 mit jeweils einer Zylinderschlosseinheit 6a jeweils nur einen einzigen Schlüssel aufweisen. Da für die Verriegelung immer nur ein Schalter 1 eingeschaltet sein darf, darf der Schlüssel nur in einer Position (nämlich der Verriegelt-Position des Schalters 1) abziehbar sein. Auf diese Weise kann man mit der Zylinderschlosseinheit durch einfachen Austausch der Zylinderschlösser beide Funktionen, Verriegeln und Abschließen, verwirklichen.The cylinder lock units 6a can be used for locking and closing the switch 1. Termination means that each cylinder lock unit 6a has its own key that can be withdrawn in the locked key position (switch OFF) and in the non-terminated key position (switch ON). Locking means that, for example, two switches 1 each having a cylinder lock unit 6a each have only a single key. Since only one switch 1 may be switched on for the locking, the key may only be removable in one position (namely the locked position of the switch 1). In this way, you can with the cylinder lock unit by simply replacing the cylinder locks both functions, locking and locking, realize.
