Abstract

A switching device is specified which consists of a switching chamber region whose contact link carrier is coupled to a switching bolt. Inside the contact link carrier (15) there are arranged moving contacts (12, 13) on contact links (18) on which compression springs act. By means of rams (16) arranged in the contact link carriers (15), the contacts (12, 13) can be operated by means of switching devices which can be installed differently, in the sense of a contact opening, while the rams (16) are acted on directly and without delay by trip devices associated with each switching path, while the trip device (4) at the same time acts on the switching bolt (2) and trips its energy store. For switching in use, an electromagnetic drive (3) is provided which acts by means of a lever (31) on all the rams (16) simultaneously and opens all the moving contacts simultaneously. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Schaltvorrichtung, bestehend aus einem Schaltkammerbereich mit darin befindlichen feststehenden und dieser verbindenden beweglichen Kontakten, einem Schaltschloß, das mit einem Energiespeicher ausgerüstet ist, der mittels eines Handbetätigungselementes gespannt wird, und das mit dem Kontaktbrückenträger der beweglichen Kontakte gekoppelt ist.The invention relates to a switching device, consisting of a switching chamber area with fixed and connecting movable contacts located therein, a switch lock, which is equipped with an energy store, which is tensioned by means of a manual actuating element, and which is coupled to the contact bridge support of the movable contacts.

Derartige Schaltvorrichtungen sind bereits in unter­schiedlichen Bauarten bekannt. Sie werden üblicher­weise in Schaltgeräten eingesetzt, die Motoren einer­seits betriebsmäßig schalten und andererseits gegen Überströme schützen sollen. Das betriebsmäßige Schal­ten erfolgt entweder über ein Schaltschloß mit Hand­antrieb oder über einen Magnetantrieb in der Art eines Schützes, während der Schutz gegen Überströme durch Auslöseorgane, die über das Schaltschloß auf die beweglichen Kontakte wirken, gewährleistet wird. Die europäische Patentanmeldung 179 677 beschreibt eine Schaltvorrichtung dieser Art, bei der ein An­triebsorgan und ein Steuerorgan mit Kraftspeicher direkt auf die beweglichen Kontakte wirken, während ein weiteres Steuerorgan über den Kraftspeicher indirekt die Kontaktöffnung bewirkt. Bei hohen Überströmen, beispielsweise im Falle eines Kurzschlusses, ist für die Kontaktbahnen einerseits eine schnelle ausrei­chende Öffnung der betroffenen Strombahn erforder­lich, andererseits soll das Schaltgerät dauerhaft ausschalten.Such switching devices are already known in different designs. They are usually used in switchgear that, on the one hand, switches motors in operation and, on the other hand, is designed to protect against overcurrents. The operational switching takes place either via a switch lock with manual drive or via a magnetic drive in the manner of a contactor, while protection against overcurrents is ensured by tripping elements which act on the movable contacts via the switch lock. European patent application 179 677 describes a switching device of this type in which a drive element and a control element with an energy store act directly on the movable contacts, while a further control element indirectly causes the contact opening via the energy store. In the event of high overcurrents, for example in the event of a short circuit, the contact paths on the one hand require the relevant current path to be opened quickly and sufficiently, and on the other hand the switching device should switch off permanently.

Der Erfindung liegt die Aufgabe zugrunde, eine Schalt­vorrichtung zu schaffen, die mittels eines magnetischen Antriebs alle Strombahnen betriebsmäßig schaltet, bei der jedoch im Falle hoher Überströme eine oder mehrere Strombahnen sofort direkt und unabhängig geöffnet werden und nahezu gleichzeitig der Energie­speicher des über das Schaltschlosses ausgelöst und das gesamte Schaltgerät ausgeschaltet wird.The invention has for its object to provide a switching device that switches all current paths operationally by means of a magnetic drive, in which, however, one or more current paths are opened immediately and independently in the event of high overcurrents and almost simultaneously the energy storage device is triggered via the switch lock and the entire switching device is switched off.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beweglichen Kontakte innerhalb des Kontakt­brückenträgers durch Druckfedern beaufschlagt sind, die im eingeschalteten Zustand der Schaltvorrichtung den Kontaktdruck bewirken, und durch im Kontaktbrücken­träger beweglich angeordnete Stößel gegen den Druck der Druckfedern im Sinne der Kontaktöffnung betätigt werden können, und daß diese Stößel durch Aussparungen im Kontaktbrückenträger durch unterschiedliche anbau­bare Schalteinrichtungen gegen die beweglichen Kontakte bewegt werden können und die Schaltstrecken aller oder einzelner Pole öffnen.
Ein elektromagnetischer Antrieb wirkt über einen mehrarmigen Hebel auf alle Stößel gleichzeitig und öffnet alle Schaltstrecken im Sinne der Funktion eines Schützes gegen den Druck der Kontaktdruckfeder. Dabei ist jeder Schaltstrecke ist eine Auslösevor­richtung zugeordnet, die über einen Winkelhebel direkt auf den in dem Kontaktbrückenträger angeordneten Stößel wirkt und damit im Störungsfall eine Schnell­öffnung der betroffenen Kontaktbrücke bewirkt, und die gleichzeitig auf das Schaltschloß im Sinne der Auslösung des Energiespeichers wirkt und eine an­dauernde Öffnung aller Schaltstrecken zur Folge hat.This object is achieved in that the movable contacts within the contact bridge support are acted upon by compression springs which bring about the contact pressure when the switching device is switched on, and can be actuated by means of plungers movably arranged in the contact bridge support against the pressure of the compression springs in the sense of the contact opening, and that these plungers can be moved against the movable contacts through cutouts in the contact bridge support by different attachable switching devices and open the switching paths of all or individual poles.
An electromagnetic actuator acts on all plungers simultaneously via a multi-arm lever and opens all switching distances in the sense of the function of a contactor against the pressure of the contact pressure spring. Each switching path is assigned a trigger device, which acts via an angle lever directly on the plunger arranged in the contact bridge carrier and thus causes the affected contact bridge to open quickly in the event of a fault, and which simultaneously acts on the switching lock in the sense of triggering the energy store and has a permanent opening of all switching distances.

Die Schaltstrecken derartiger Schaltgeräte haben bei hohen Überströmen das Bestreben, die Kontakte zu öffnen und eine Lichtbogenstrecke zu bilden. Hier­durch besteht aufgrund des Anschmelzens des Kontakt­materials die Gefahr des Verschweißens. Diese Gefahr läßt sich nun erheblich reduzieren, wenn die Schalt­strecken vor dem Erreichen des Abhebestroms zwangs­läufig soweit geöffnet werden, daß der Lichtbogen verlängert und in die Löschkammern getrieben wird. Dieser Vorgang sollte direkt und ohne Zeitverzögerung bei dem Auftreten der Überströme ablaufen. Das wird bei dem erfindungsgemäßen Schaltgerät dadurch erreicht, daß der Schnellauslöser direkt und unabhängig von den weiteren vorhandenen Antrieben auf die betroffenen Schaltstrecken wirken kann. Hierdurch entfällt die Eigenzeit des Schaltschlosses, das erst durch einen Arm des auf die Schaltstrecke wirkenden Hebels ent­klinkt wird und die endgültige Öffnung herbeiführt.In the case of high overcurrents, the switching paths of such switching devices endeavor to open the contacts and to form an arc path. As a result, there is a risk of welding due to the melting of the contact material. This risk can now be reduced considerably if the switching paths are inevitably opened before the lifting current is reached so that the arc is extended and driven into the quenching chambers. This process should take place directly and without any time delay when the overcurrents occur. This is achieved in the switching device according to the invention in that the quick release can act directly and independently of the other drives present on the switching paths concerned. This eliminates the intrinsic time of the key switch, which is only released by an arm of the lever acting on the switching path and brings about the final opening.

Anhand der beiliegenden Zeichnungen soll ein Ausführungs­beispiel der Erfindung dargestellt und näher erläutert werden.An exemplary embodiment of the invention is to be illustrated and explained in more detail with reference to the accompanying drawings.

In der Fig. 1 sind die Funktionselemente der Schaltvor­richtung schematisch dargestellt. Das Grundelement besteht aus einem Schaltkammerbereich 1 und einem Schaltschloß 2. In dem Schaltkammerbereich 1 sind die feststehenden Kontakte 10, 11 angeordnet, die über Strombahnen 101, 102 mit den Anschlußklemmen 103 und 104 verbunden sind.In Fig. 1, the functional elements of the switching device are shown schematically. The basic element consists of a switching chamber area 1 and a switch lock 2. In the switching chamber area 1, the fixed contacts 10, 11 are arranged, which are connected via current paths 101, 102 to the connecting terminals 103 and 104.

Die feststehenden Kontakte 10, 11 werden über die beweglichen Kontakte 12, 13 und die Kontaktbrücke 18 je nach Schaltstellung verbunden oder getrennt. Die Kontaktbrücke 18 ist in einem Kontaktbrückenträger 15 derart gelagert, daß sie in der Ein-Stellung des Schaltgerütes durch die Kontaktdruckfeder 14 gegen die feststehenden Kontakte 10, 11 gedrückt wird, während sich die Kontaktdruckfeder am Boden des Kon­taktbrückenträgers 15 abstützt. Der Kontaktbrücken­träger 15 ist mit den Schaltschloß 2 gekoppelt, das in der Ein-Stellung über den Kontaktbrückenträger 15 die Gegenkraft zur Kontaktdruckfeder 14 darstellt und damit die beweglichen Kontakte 12, 13 gegen die feststehenden Kontakte 10, 11 drückt. Das Schalt­schloß 2 wird mittels einer Handhabe 21 in den ge­spannten Zustand geschaltet.The fixed contacts 10, 11 are connected or disconnected via the movable contacts 12, 13 and the contact bridge 18 depending on the switching position. The contact bridge 18 is mounted in a contact bridge carrier 15 such that it is pressed in the on position of the switching device by the contact pressure spring 14 against the fixed contacts 10, 11, while the contact pressure spring is supported on the bottom of the contact bridge carrier 15. The contact bridge support 15 is coupled to the switching mechanism 2, which in the on position via the contact bridge support 15 represents the counterforce to the contact pressure spring 14 and thus presses the movable contacts 12, 13 against the fixed contacts 10, 11. The switching lock 2 is switched into the tensioned state by means of a handle 21.

In dem Kontaktbrückenträger 15 ist ein Stößel 16 in Bewegungsrichtung des Kontaktbrückenträgers 15 verschiebbar angeordnet. Dieser Stößel 16 steht einer­seits unter der Wirkung von Hebeln 31 und 41, anderer­seits liegt er an der Kontaktbrücke 18 an. Mittels dieses Stößels 16 ist es daher möglich, die Bewe­gung der Hebel 31 und 41 gegen den Druck der Kontakt­druckfeder 14 im Sinne der Kontaktöffnung auf die beweglichen Kontakte 12, 13 zu übertragen.
Der Hebel 41 steht unter der Wirkung eines Überstrom­auslösers 4 und hat die Aufgabe, im Falle eines Über­stromes die Bewegung des Auslösestößels 43 ohne Zeit­verzug auf die beweglichen Kontakte zu übertragen.A plunger 16 is arranged displaceably in the direction of movement of the contact bridge carrier 15 in the contact bridge carrier 15. This plunger 16 is on the one hand under the action of levers 31 and 41, on the other hand it bears against the contact bridge 18. By means of this plunger 16, it is therefore possible to transmit the movement of the levers 31 and 41 against the pressure of the contact pressure spring 14 in the sense of the contact opening to the movable contacts 12, 13.
The lever 41 is under the action of an overcurrent release 4 and has the task of transmitting the movement of the release plunger 43 to the movable contacts without delay in the event of an overcurrent.

Der Hebel 41 weist dabei zwei Schenkel 41a und 41b auf. Während der Schenkel 41a die unverzögerte jedoch vorübergehende Öffnung der Kontakte bewirkt, erfolgt über den zweiten Schenkel 41b und der Zwischenschaltung eines Stößel 42 die Entklinkung des Schaltschlosses 2 und damit die endgültige Öffnung der Schaltstrecken. Dabei ist jeder Schaltstrecke ein Überstromauslöser 4 zugeordnet.The lever 41 has two legs 41a and 41b. While the leg 41a causes the instantaneous but temporary opening of the contacts, the second leg 41b and the interposition of a plunger 42 unlatch the switching lock 2 and thus the final opening of the switching paths. An overcurrent release 4 is assigned to each switching path.

Zum betriebsmäßigen Schalten der Schaltvorrichtung ist auf der den Überstromauslösern 4 gegenüberlie­genden Seite ein Magnetantrieb 3 vorgesehen, der mittels eines Winkelhebels 31 auf die Stößel 16 wirkt und gegen den Druck der Kontaktdruckfeder 14 die Schaltstrecken öffnet. Der Winkelhebel 31 ist ent­sprechend der Anzahl der Strombahnen derart ausgeführt, daß er alle Schaltstrecken gleichzeitig öffnet.For operational switching of the switching device, a magnetic drive 3 is provided on the side opposite the overcurrent release 4, which acts on the plunger 16 by means of an angle lever 31 and opens the switching paths against the pressure of the contact pressure spring 14. The angle lever 31 is designed according to the number of current paths in such a way that it opens all switching paths simultaneously.

Den Kontaktbrückenträger 15 und die Zuordnung der Hebel 31 und 41 zeigen die Fig. 2 und 3. Fig. 2 zeigt den Kontaktbrückenträger 15 in einer Seitenansicht. Hierbei erkennt man die Verbindung zu dem Schalt­schloß 2, das im Falle einer Schaltung den gesamten Kontaktbrückenträger 15 bewegt und alle Strombahnen gleichzeigt öffnet. Eine nahezu gleichzeitige Öffnung der Strombahnen wird auch durch die Schaltung des Magentantriebes 3 erreicht, der über den insbesondere in Fig. 3 erkennbaren Hebel 31 auf alle Stößel 16 gleichzeigt wirkt und über diese die Kontaktbrücke 18 in die Offen-Stellung bewegt. Die Öffnung einer ein­zelnen Kontakbrücke erfolgt, wenn ein hoher Überstrom (Kurzschlußstrom) eine der Strombahnen belastet und dieser Strombahn zugehörigen Überstromauslöser 4 aktiviert. Dieser betätigt den zugeordneten Hebel 41 bzw. 41ʹ bzw. 42ʺ direkt und über den entsprechen­den Stößel 16 wird die Kontaktbrücke 18 der belasteten Strombahnen gegen den Druck einer Feder 14 abgehoben.The contact bridge carrier 15 and the assignment of the levers 31 and 41 are shown in FIGS. 2 and 3. FIG. 2 shows the contact bridge carrier 15 in a side view. Here you can see the connection to the switching mechanism 2, which moves the entire contact bridge support 15 in the event of a circuit and opens all current paths in the same direction. An almost simultaneous opening of the current paths is also achieved by switching the magnetic drive 3, which acts in the same way on all plungers 16 via the lever 31, which can be seen in particular in FIG. 3, and moves the contact bridge 18 into the open position via these. A single contact bridge is opened when a high overcurrent (short-circuit current) loads one of the current paths and activates the overcurrent release 4 associated with this current path. This actuates the associated lever 41 or 41ʹ or 42ʺ directly and the contact plunger 16 of the loaded current paths is lifted off against the pressure of a spring 14 via the corresponding plunger 16.
