Abstract

The switch has an actuator with electromagnets whose magnetic force pushes an actuating element (2) to an actuating position during short circuit. The actuating element actuates a switching unit for separating switching contacts in the actuating position, and a pilot switch module (1) has a blocking element (5) moved from a blocking position to a release position during short circuit. The blocking element releases movement of a signaling element (3) i.e. push rod, in a signaling position, where the blocking element is moved to the release position by the actuating element during short circuit.

Description

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

Leistungsschalter für Niederspannungen sind allgemein bekannt und bewirken die Unterbrechung des durch den Schalter fließenden Stroms im Falle eines Überstroms oder Kurzschlusses. Der Strom fließt dabei über Schaltkontakte, die bei Überstrom oder Kurzschluss voneinander getrennt werden. Zum Trennen der Schaltkontakte dient ein Auslöser, dessen Elektromagnet ebenfalls von dem Strom durchflossen wird und der im Kurzschlussfall aufgrund der dabei erzeugten relativ großen Magnetkräfte einen Schieber verschiebt. Dieser wirkt auf ein vorgespanntes Schaltschloss ein, welches die Schaltkontakte trennt.Low voltage circuit breakers are well known and cause the interruption of the current flowing through the switch in the event of an overcurrent or short circuit. The current flows via switch contacts which are disconnected in the event of overcurrent or short circuit. To disconnect the switch contacts is a trigger whose electromagnet is also traversed by the current and shifts a slide in the case of short circuit due to the relatively large magnetic forces generated thereby. This acts on a preloaded switch lock, which separates the switch contacts.

Derartige Auslöser weisen zur Überstromerkennung fast immer eine zusätzliche thermische Einheit auf, so dass es nicht ohne Weiteres möglich ist, zu erkennen, ob ein Überstrom oder ein Kurzschluss zur Auslösung des Schalters geführt hat.Such triggers almost always have an additional thermal unit for overcurrent detection, so that it is not readily possible to detect whether an overcurrent or a short circuit has led to the tripping of the switch.

Die Aufgabe der Erfindung ist es, ein nachrüstbares Meldeschalter-Modul anzugeben, welches eine Kurzschluss-Auslösung signalisiert.The object of the invention is to specify a retrofittable signaling switch module which signals a short-circuit tripping.

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

Die Lösung sieht vor, dass ein in den Schalter eingesetztes Meldeschalter-Modul ein Blockierelement und ein verschiebbares Signalisierungselement aufweist, wobei das Blockierelement aus einer Blockierstellung in eine Freigabestellung bewegt wird, in der es die Verschiebung des Signalisierungselements in eine Signalisierungsstellung freigibt, und dass das Blockierelement bei einem Kurzschluss durch das Auslöseelement in seine Freigabestellung bewegt wird. Der Kerngedanke der Erfindung besteht also darin, das Blockierelement des Meldeschalter-Moduls mit dem vorhandenen Auslöseelement des Schalters zusammenwirken zu lassen, d. h. das Auslöseelement gibt das Blockierelement frei, so dass das Signalisierungselement einen Kurzschluss anzeigen oder die Anzeige z. B. durch Schalterbetätigung auslösen kann.The solution provides that a detector switch module inserted into the switch has a blocking element and a displaceable signaling element, wherein the blocking element is moved from a blocking position to a release position, in which it releases the displacement of the signaling element in a signaling position, and that the blocking element is moved in a short circuit by the trigger element in its release position. The core idea of the invention is thus to let the blocking element of the signaling switch module cooperate with the existing trigger element of the switch, ie the triggering element releases the blocking element, so that the signaling element indicate a short circuit or the display z. B. can trigger by switch operation.

Eine technisch einfache Ausführung sieht vor, dass das Blockierelement als drehgelagerter Entklinkungshebel und das Auslöseelement als Auslöseschieber ausgebildet sind, wobei der Auslöseschieber eine Ausnehmung oder Verjüngung aufweist, in die ein Ende des Entklinkungshebels bei in seiner Auslösestellung befindlichem Auslöseschieber eingeschwenkt ist, während das andere Ende des Entklinkungshebels das Signalisierungselement freigibt.A technically simple embodiment provides that the blocking element are designed as a rotatably mounted Entklinkungshebel and the trigger element as a trigger slide, wherein the trigger slide has a recess or taper, in which one end of the Entklinkungshebels is pivoted in befindlichem in its release position trip slider, while the other end of Entklinkungshebels the signaling element releases.

Im einfachsten Fall sorgt eine Federkraft dafür, dass das freigegebene Signalisierungselement in seine Signalisierungsstellung verschoben wird.In the simplest case, a spring force ensures that the released signaling element is shifted into its signaling position.

Um die Kurzschlussauslösung quasi an einem beliebig entfernten Ort anzuzeigen, wird vorgeschlagen, dass das Signalisierungselement mittels der Federkraft einen elektrischen Signalisierungsschalter betätigt.In order to display the short-circuit release virtually at an arbitrarily remote location, it is proposed that the signaling element actuates an electrical signaling switch by means of the spring force.

Um einen Kurzschluss anzuzeigen und gleichzeitig ein versehentliches Wiedereinschalten des Schalters zu verhindern, wird vorgeschlagen, dass die Federkraft über das freigegebene Signalisierungselement einen Quittier- und Anzeigeknopf nach außen schiebt, der nach außen verschobene Quittier- und Anzeigeknopf die Kurzschlussauslösung anzeigt und durch Drücken des Quittier- und Anzeigeknopfs das Signalisierungselement und das Auslöseelement über das Blockierelement wieder zurückgeschoben werden.In order to indicate a short circuit and at the same time to prevent the switch from being accidentally switched on again, it is proposed that the spring force relay via the released signaling element an acknowledgment and display button externally pushes, moved outward acknowledgment and display button displays the short-circuit release and the signaling element and the trigger element are pushed back on the blocking element by pressing the acknowledgment and display button.

Zweckmäßig ist es, wenn das Blockierelement bei zurückgeschobenem Signalisierungselement wieder in die Freigabestellung bewegbar ist.It is expedient if the blocking element can be moved back into the release position when the signaling element is pushed back.

Eine technisch einfache Ausführung sieht vor, dass das Signalisierungselement als Stößel ausgebildet ist.A technically simple embodiment provides that the signaling element is designed as a plunger.

Figur 1 zeigt ein Meldeschalter-Modul 1 für einen Leistungsschalter (im Folgenden kurz Schalter genannt) für Niederspannungen in einer schematischen Darstellung. Der Schalter verfügt über nicht gezeigte Schaltkontakte, über die der Strom fließt und die bei einem Kurzschluss zur Unterbrechung des Stroms voneinander getrennt werden. Weiter ist im Schalter ein Auslöser angeordnet, zu dem ein Elektromagnet gehört, welcher zumindest teilweise von dem Strom durchflossen wird. Im Falle eines Kurzschlusses verschieben die Magnetkräfte des Elektromagneten ein Auslöseelement 2 in Form eines magnetischen Auslöseschiebers 2a in seine Auslösestellung. In der Auslösestellung betätigt der Auslöseschieber 2a eine vorgespannte Schalteinheit (ein Schaltschloss, nicht gezeigt), welche die Trennung der Schaltkontakte in bekannter Art und Weise bewirkt. FIG. 1 shows a signaling switch module 1 for a circuit breaker (hereinafter referred to as switch briefly) for low voltages in a schematic representation. The switch has via switching contacts, not shown, over which the current flows and which are separated from each other in the event of a short circuit for interrupting the current. Next, a trigger is arranged in the switch, to which an electromagnet belongs, which is at least partially traversed by the current. In the case of a short circuit, the magnetic forces of the electromagnet shift a triggering element 2 in the form of a magnetic release slide 2a in its release position. In the release position, the trigger slide 2a actuates a biased switching unit (a switch lock, not shown), which causes the separation of the switch contacts in a known manner.

Das in den Schalter durch Verrastung einsetzbare Meldeschalter-Modul 1 weist ein Signalisierungselement 3 in Form eines Stößels 3a auf, der im Meldeschalter-Modul 1 längsverschiebbar gelagert ist. Der Stößel 3a wird durch eine Feder 4 kraftbeaufschlagt, welche den Stößel 3a in Figur 1 nach oben drückt. Die Verschiebung des Stößels 3a nach oben wird durch ein Blockierelement 5 in Form eines Entklinkungshebels 5a begrenzt; der Entklinkungshebel 5a befindet sich in Figur 1 in seiner Blockierstellung. Wie Figur 1 weiter erkennen lässt, wird der Entklinkungshebel 5a vom Stößel 3a gegen den Auslöseschieber 2a gedrückt.The switch switch module which can be inserted into the switch by latching has a signaling element 3 in the form of a plunger 3a, which is mounted longitudinally displaceable in the signaling switch module 1. The plunger 3a is urged by a spring 4, which the plunger 3a in FIG. 1 pushes up. The displacement of the plunger 3a upwards is limited by a blocking element 5 in the form of a Entklinkungshebels 5a; the unlatching lever 5a is located in FIG. 1 in its blocking position. As FIG. 1 can be further seen, the unlatching lever 5a is pressed by the plunger 3a against the trigger slide 2a.

Der Auslöseschieber 2a weist eine nutförmige Ausnehmung 6 auf, welche für das entsprechende Zusammenwirken der drei Elemente Stößel 3a, Entklinkungshebel 5a und Auslöseschieber 2a sorgt.The release slide 2a has a groove-shaped recess 6, which ensures the corresponding interaction of the three elements ram 3a, unlatching lever 5a and release slide 2a.

Figur 2 zeigt das Meldeschalter-Modul 1 nach Auftreten eines Kurzschlusses, mit von der Magnetkraft des Elektromagneten gegen die Kraft der Feder 7 in seine Auslösestellung verschobenem Auslöseschieber 2a. Der Entklinkungshebel 5a ist vom Stößel 3a mit einem seiner beiden freien Enden in die Vertiefung 6 und damit in seine Freigabestellung bewegt worden (eingeschwenkt). Der Auslöseschieber 2a wird in Figur 2 weiter durch den Entklinkungshebel 5a in seiner Auslösestellung gehalten. Der Stößel 3a wiederum ist durch die Feder 4 in seine obere (End-)Stellung verschoben worden, d. h. er befindet sich in Figur 2 in seiner Signalisierungsstellung, in der er gegen einen elektrischen Signalisierungsschalter 8 drückt und diesen betätigt. FIG. 2 shows the signaling switch module 1 after occurrence of a short circuit, with the magnetic force of the electromagnet against the force of the spring 7 in its release position shifted release slide 2a. The unlatching lever 5a is of Plunger 3a has been moved with one of its two free ends in the recess 6 and thus in its release position (pivoted). The shutter slide 2a is in FIG. 2 further held by the unlatching lever 5a in its release position. The plunger 3a in turn has been moved by the spring 4 in its upper (end) position, ie it is located in FIG. 2 in its signaling position in which he presses against an electrical signaling switch 8 and actuates it.

In der Signalisierungsstellung kann der aus dem Meldeschalter-Modul 1 herausragende Stößel 3a durch das Herausragen bereits die Kurzschlussauslösung anzeigen.In the signaling position, the protruding from the signaling switch module 1 plunger 3a by protruding already indicate the short-circuit release.

Figur 3 zeigt eine Seitenansicht des Meldeschalter-Moduls 1 mit einem Quittier- und Anzeigeknopf 9, der mit einem quer zum Stößel 3a verlaufenden Bolzen 10 zusammenwirkt, wobei eine am Quittier- und Anzeigeknopf 9 ausgebildete Schräge 11 diesen nach rechts aus dem Meldeschalter-Modul 1 verschiebt, wenn der Stößel 3a nach oben verschoben wird (nach rechts und nach oben beziehen sich jeweils auf Figur 3). Der aus dem Schalter herausragende Quittier- und Anzeigeknopf 9 zeigt nach außen eine Kurzschlussauslösung an. FIG. 3 shows a side view of the signaling switch module 1 with an acknowledgment and display button 9, which cooperates with a bolt 10 extending transversely to the plunger 3a, wherein a bevel formed on the acknowledgment and display button 9 11 moves it to the right from the signaling switch module 1, when the plunger 3a is moved upwards (to the right and up respectively refer to FIG. 3 ). The outstanding from the switch acknowledgment and display button 9 indicates to the outside a short-circuit release.

Der Quittier- und Anzeigeknopf 9 ist in Figur 3 genauer zu sehen.The acknowledgment and display button 9 is in FIG. 3 to see more closely.

Umgekehrt bewirkt ein Verschieben des Quittier- und Anzeigeknopfs 9 nach links eine Verschiebung des Stößels 3a nach unten. Durch Drücken des Quittier- und Anzeigeknopfs 9 wird der Stößel 3a wieder nach unten geschoben und gleichzeitig das Einschalten des Schalters quittiert.Conversely, a shift of the acknowledgment and display button 9 to the left causes a displacement of the plunger 3a down. By pressing the acknowledgment and display button 9, the plunger 3a is again pushed down and at the same time acknowledged the switching on of the switch.

Bei zurückgeschobenem Stößel 3a kann der Entklinkungshebel 5a wieder in seine Blockierstellung schwenken.When pushed back plunger 3a, the unlatching lever 5a can pivot back into its blocking position.

Figur 5 zeigt das Einstecken des Meldeschalter-Moduls 1 in den Schalter, welches einfach eingeschoben wird und dabei im Schalter verrastet. Anschließend wird (s. geraden Pfeil in Figur 5) der Stößel 3a direkt nach unten gedrückt, während der Entklinkungshebel 5a auf den Auslöseschieber 2a trifft, wodurch der Entklinkungshebel 5a in seine Blockierstellung geschwenkt wird. Anschließend wird der Stößel 3a wieder losgelassen und von der Feder 4 bis zum Anschlagen am Entklinkungshebel 5a nach oben verschoben. FIG. 5 shows the insertion of the signaling switch module 1 in the switch, which is simply inserted while it is locked in the switch. Then (see straight arrow in FIG. 5 ) pushes the plunger 3a directly down, while the unlatching lever 5a meets the trigger slide 2a, whereby the unlatching lever 5a is pivoted to its blocking position. Subsequently, the plunger 3a is released again and moved by the spring 4 until it stops at the unlatching lever 5a upwards.
