Description

Die Erfindung betrifft ein Kombinationsschaltgerät mit einem Schütz und einem daran befestigten thermischen Überstromrelais.The invention relates to a combination switching device with a contactor and one thereon attached thermal overcurrent relay.

Bekannte Überstromrelais besitzen aus einer Seitenwandung herausragende, steife Leiterstücke, die in die Anschlußklemmen des Schützes hineingesteckt und darin be­ festigt werden. Damit wird das Überstromrelais über die Leiterstücke und die An­ schlußklemmen des Schützes an dem Schütz fixiert. Da die Leiterstücke dauernd aus dem Gehäuse des Überstromrelais herausragen, können sie sich bei Lagerung verbie­ gen, was dann Montageprobleme mit sich bringen kann.Known overcurrent relays have protruding, stiff ones from a side wall Conductor pieces, which are inserted into the contactor's terminals and be be consolidated. The overcurrent relay is thus connected to the conductor sections and the An the contactor's terminal clamps are fixed to the contactor. Because the ladder is constantly out protruding from the housing of the overcurrent relay, they can become distorted during storage conditions, which can then lead to assembly problems.

Aufgabe der Erfindung ist es, ein Kombigerät zu schaffen, bei dem diese Nachteile vermieden sind.The object of the invention is to provide a combination device in which these disadvantages are avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Schütz mit dem Über­ stromrelais mittels einer Rastverbindung verbindbar ist, und daß im Überstromrelais Stromwandler vorgesehen sind, durch die Kupplungsleitungen hindurchsteckbar sind, die mit Anschlußklemmen am Schütz elektrisch leitend verbunden sind. This object is achieved in that the contactor with the over current relay can be connected by means of a latching connection, and that in the overcurrent relay Current transformers are provided, through which coupling lines can be inserted, which are connected in an electrically conductive manner to terminals on the contactor.  

Damit sind an dem Überstromrelais keine vorstehenden Leiterstücke mehr vorgesehen; Lagerhaltungsprobleme ergeben sich durch solche sperrig vorstehenden Leiter nicht mehr.This means that no protruding conductor sections are provided on the overcurrent relay; Storage problems do not arise from such bulky projecting conductors more.

Daß das Überstromrelais in diesem Fall ein sog. elektronisches Relais ist, mit dem Überströme elektronisch erfaßt werden, ist hier Voraussetzung.That the overcurrent relay in this case is a so-called electronic relay with which Overcurrents are recorded electronically here.

Das Gehäuse des Überstromrelais besitzt in der dem Schütz zugewandten Seitenwan­ dung Löcher, die mit den Öffnungen der Stromwandler innerhalb des Überstromrelais fluchten.The housing of the overcurrent relay has in the side wall facing the contactor holes with the openings of the current transformers inside the overcurrent relay swear.

Dabei sind am Überstromrelais Rastarme vorgesehen, die im montierten Zustand hinter Vorsprünge am Schütz einrasten.In this case, latching arms are provided on the overcurrent relay, which behind in the assembled state Snap the protrusions onto the contactor.

Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen und weitere Vorteile der Erfindung näher erläutert und beschrieben werden.Using the drawing, in which an embodiment of the invention is shown, the invention and further advantageous refinements and improvements and further advantages of the invention are explained and described in more detail.

Es zeigt die einzige Figur eine Teilschnittansicht eines Schützes mit einem Überstromrelais.The sole figure shows a partial sectional view of a contactor with a Overcurrent relay.

An einem Schütz 10a, dessen Außengehäuse mit 11 bezeichnet ist, wird ein Über­ stromrelais 10b angeschlossen. An der Innenseite der Seitenwandung 12 des Schützes befinden sich Vorsprünge 13, 14 die senkrecht nach innen, also ins Innere des Schüt­ zes, vorragen. In der oberen und unteren Wandung (siehe Zeichnung) sind Öffnungen 15, 16 vorgesehen, deren Wirkungsweise weiter unten erläutert wird. An der dem Schütz benachbarten Wand 17 des Überstromrelais 10b ist eine der Anzahl von Durch­ steckleitungen 19 entsprechende Anzahl von Öffnungen 18 vorgesehen, hinter denen jeweils ein Wandler 21 angeordnet ist, der eine Öffnung 21a aufweist, die mit den Lö­ chern 18 fluchten. An einer Anschlußklemme 20 im Schütz ist der Durchsteckleiter 19 befestigt, dessen im Inneren des Überstromrelais 10b befindliches Ende mittels einer Schraubenverbindung 29 mit einem Anschluß 22 verbunden ist, der an einer elektroni­ schen Einheit 24 angeschlossen ist und zu einer nicht näher dargestellten Anschluß­ klemme am Überstromrelais 10b verläuft.On a contactor 10 a, whose outer housing is designated 11 , an over-current relay 10 b is connected. On the inside of the side wall 12 of the contactor there are projections 13 , 14 which protrude vertically inwards, ie into the interior of the contactor. Openings 15 , 16 are provided in the upper and lower walls (see drawing), the mode of operation of which is explained below. On the contactor adjacent wall 17 of the overcurrent relay 10 b one of the number of feed-through lines 19 corresponding number of openings 18 is provided, behind each of which a converter 21 is arranged, which has an opening 21 a, which are aligned with the holes 18 . At a terminal 20 in the contactor, the push-through conductor 19 is fastened, the end of which is located inside the overcurrent relay 10 b is connected by means of a screw connection 29 to a terminal 22 which is connected to an electronic unit 24 and to a terminal, not shown, on Overcurrent relay 10 b runs.

Der Wandler 21 besitzt eine nicht dargestellte Wicklung, deren Wicklungsenden 30, 31 mit der elektronischen Auswerteeinheit 24 elektrisch leitend verbunden sind. Durch den Leiter 19 durchfließender Strom wird in dem Stromwandler 21 detektiert und von der Auswerteeinheit 24 ausgewertet; bei Überschreiten eines bestimmten Stromwertes werden die Kontaktstellen im Schütz geöffnet.The converter 21 has a winding, not shown, whose winding ends 30 , 31 are electrically conductively connected to the electronic evaluation unit 24 . Current flowing through the conductor 19 is detected in the current transformer 21 and evaluated by the evaluation unit 24 ; if a certain current value is exceeded, the contact points in the contactor are opened.

An der Wandung 17 sind Rastarme 25 und 26 angeformt, die mit Rastnasen 27 und 28 hinter die Vorsprünge 13, 14 greifen, so daß das Überstromrelais 10b am Schütz 10a durch Verrastung festgelegt werden kann. Die Öffnungen 15 und 16 dienen dazu, daß die Arme 25 und 26 nach außen ausbiegen können. Die Öffnungen, durch die die Arme hindurchgreifen, sind mit den Bezugsziffern 32 und 33 bezeichnet.On the wall 17 locking arms 25 and 26 are formed, which engage with locking lugs 27 and 28 behind the projections 13 , 14 , so that the overcurrent relay 10 b on the contactor 10 a can be fixed by latching. The openings 15 and 16 serve that the arms 25 and 26 can bend outwards. The openings through which the arms reach are identified by the reference numbers 32 and 33 .

Die Anordnung ist dreiphasig, benutzt also für jede Phase eine Anschlußklemme 20, einen Leiter 19 und einen Wandler 21.The arrangement is three-phase, that is to say uses a connecting terminal 20 , a conductor 19 and a converter 21 for each phase.
