Abstract

The invention relates to a switching device, consisting of a power switching apparatus (1) having a short-circuit and overload trigger device and having an auxiliary switching device (2) which can be fitted to the outside of the housing of the power switching apparatus and preferably has two pairs of auxiliary contacts which are designed as normally closed contacts (95,96) and normally open contacts (97,98) and are closed or opened by means of moving contact links. The overload trip device (110) in the case of the switching device according to the invention does not lead to the power switching apparatus tripping but acts on the auxiliary switching device. This results in the advantage that the power switching apparatus does not trip in the event of a slight overload but passes a signal via an auxiliary switching device to a signalling device (S1) and operates an electromagnetic switching apparatus (114). The auxiliary switching device can be retrofitted to the power switching apparatus. In this case, a changeover lever which is supported in the auxiliary switching device projects through an opening into the power switching apparatus. The changeover lever interacts with the overload tripping device of the power switching apparatus and, in the event of an overload, switches the switching links suddenly into the respective other switching position. <IMAGE>

Description

Die Erfindung betrifft eine Schaltvorrichtung, bestehend aus einem Schaltantrieb und einem Leistungsschaltgerät, wobei an dem Leistungsschaltgerät eine an der Gehäuseaußenseite nachträglich anbaubare Hilfsschaltvorrichtung vorgesehen ist, mit vorzugsweise zwei Hilfskontaktpaaren, die als Öffner- und Schließerkontakt ausgeführt sind und die jeweils mittels einer beweglichen Kontaktbrücke je nach der vorgesehenen Funktion zu einer geschlossenen Strombahn verbunden sind.The invention relates to a switching device, consisting of a switching drive and a power switching device, wherein an auxiliary switching device that can be retrofitted to the housing exterior is provided on the power switching device, preferably with two auxiliary contact pairs, which are designed as normally closed and normally open contacts and which each have a movable contact bridge depending on the intended function are connected to a closed current path.

Marktüblich sind Reihenschaltungen von Leistungsschaltgeräten, Schützen und thermischen Schutzrelais. Eine derartige Kombination ist beispielweise in der US-PS 3 638 157 beschrieben.Series connections of power switching devices, contactors and thermal protection relays are common on the market. Such a combination is described, for example, in US Pat. No. 3,638,157.

Die Überlastauslösung erfolgt durch das thermische Relais, das mittels eines Öffnerkontaktes die Selbsthaltung der Schützspule unterbricht und damit das Schütz abschaltet. Ein zweiter Schließerkontakt kann die thermische signalisieren. Kurzschlußströme werden über das Leistungschaltgerät, das damit gleichzeitig die Schutzfunktion übernimmt, abgeschaltet. Derartige Anordnungen müssen jedoch zeit- und raumaufwendig verdrahtet werden. Daher wurde versucht die Funktionen in Kompaktgeräten zu integrieren.The overload is triggered by the thermal relay, which interrupts the self-holding of the contactor coil by means of an NC contact and thus switches off the contactor. A second normally open contact can signal the thermal. Short-circuit currents are switched off via the power switching device, which thus also takes over the protective function. However, such arrangements have to be wired up in a time-consuming and space-consuming manner. Therefore, an attempt was made to integrate the functions in compact devices.

Aus der US-PS 4 258 343 ist eine Motorstarterkombination bekannt, die ein Leistungsschaltgerät mit Kurzschluß- und Überlastauslöser und einen Schaltantrieb in Form einer Schützspule aufweist. Im Überlastfall wirkt der Überlastauslöser direkt auf den Schaltantrieb. Es handelt sich um ein kompaktes Gerät mit einem starren Funktionsablauf. Für die Signalisation der Schaltzustände müssen zusätzliche Hilfsschalter vorgesehen werden. Der Überlastauslöser wirkt nur auf den Schaltantrieb und ist nicht für eine Auslösung des Schaltschlosses vorgesehen.From US-PS 4 258 343 a motor starter combination is known which has a power switching device with short-circuit and overload release and a switching drive in the form of a contactor coil. In the event of an overload, the overload release acts directly on the switching drive. It is a compact device with a rigid functional sequence. Additional auxiliary switches must be provided for signaling the switching states. The overload release only affects the switch drive and is not intended to trigger the switch lock.

Der Erfindung liegt daher die Aufgabe zugrunde, ein handelsübliches Leistungsschaltgerät, wie es als Motorschutzschalter eingesetzt werden kann, mit einfachen Mitteln und ohne aufwendige Änderung zu einem Motorstarter umzufunktionieren, der nach einer Überlastauslösung durch Fernschaltung oder durch Schaltung "vor Ort" wieder eingeschaltet werden kann.The invention is therefore based on the object of converting a commercially available power switching device, such as that which can be used as a motor protection switch, with simple means and without an expensive change to a motor starter which can be switched on again after an overload release by remote switching or by switching "on site".

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Die Wirkung des Überlastauslösers, der vorzugsweise als thermischer Auslöser ausgeführt ist, wird durch das mechanische Übertragungsmittel an den Hilfsschalter weitergegeben und veranlaßt diesen zu einer Umschaltung bzw. Signalisierung. Die Wirkkette zwischen dem thermischen Auslöser und dem Schaltschloß ist - beispielsweise durch Entfernen eines Zwischenhebels - unterbrochen, sodaß die übrigen Funktionen des Leistungsschaltgerätes, wie Schaltschloß und Kontaktsystem, von der Überlastschaltung nicht betroffen werden.The effect of the overload release, which is preferably designed as a thermal release, is passed on to the auxiliary switch by the mechanical transmission means and causes the latter to switch over or signal. The chain of action between the thermal release and the switch lock is interrupted - for example by removing an intermediate lever - so that the other functions of the power switching device, such as the switch lock and contact system, are not affected by the overload circuit.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den weiteren Ansprüchen.Advantageous embodiments of the invention result from the further claims.

Eine Umschaltung der Hilfsschaltvorrichtung kann vorteilhafterweise durch einen einfachen Umschalthebel erreicht werden, der in der Hilfsschaltvorrichtung drehbar gelagert und derart in das Leistungsschaltgerät ragt, daß er von dem Auslösehebel des Überlastauslösers betätigt wird und die Umschaltung der Hilfsschaltvorrichtung bewirkt. Die Hilfschaltvorrichtung kann so ausgeführt sei, daß der Umschalthebel auf einen Kippfedermechanismus wirkt und diesen von einer stabilen Stellung in eine zweite stabile Stellung umschaltet. Die Rückschaltung kann über ein Tastelement erfolgen, das die Rückstellung manuell erlaubt. Wenn das Tastelement in der gedrückten Stellung verrastet wird, erfolgt keine Umschaltung über den Kipppunkt und damit nach jeder Schaltung die automatische Rückstellung des Hilfsschaltgerätes. Über ein mit dem Schaltantrieb verbundenes Tastelement, das räumlich entfernt von der Schaltvorrichtung angeordnet sein kann, ist durch Anlegen des Spulenstromes die Schaltvorrichtung wieder einschaltbar.Switching of the auxiliary switching device can advantageously be achieved by a simple switching lever which is rotatably mounted in the auxiliary switching device and projects into the power switching device in such a way that it is actuated by the release lever of the overload release and causes the switching of the auxiliary switching device. The auxiliary switching device can be designed so that the switching lever acts on a toggle spring mechanism and switches this from a stable position to a second stable position. The switch back can be carried out via a pushbutton element which allows the reset manually. If the pushbutton element is locked in the pressed position, there is no changeover via the tipping point and the automatic reset of the auxiliary switching device after each switching. The switching device can be switched on again by applying the coil current via a pushbutton element which is connected to the switching drive and can be arranged at a distance from the switching device.

Bei einer derartigen erfindungsgemäßen Schaltvorrichtung muß also nur bei einer Auslösung durch einen Kurzschlußstrom vor Ort wieder eingeschaltet werden, während bei der Auslösung durch Überlast wahlweise "vor Ort" oder durch Ferneinschaltung der Motorantrieb geschaltet werden kann.In such a switching device according to the invention must thus only be switched on again when triggered by a short-circuit current on site, while when triggered by an overload, the motor drive can optionally be switched "on site" or by remote activation.

Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung näher erläutert.An exemplary embodiment of the invention is explained in more detail with reference to the drawing.

Wie aus Fig. 1 ersichtlich, ist bekannterweise einem Motor M ein Schütz K1 und ein Leistungsschaltgerät 1 in Reihe vorgeschaltet. Das Leistungsschaltgerät 1 weist einen Schnellauslöser (Kurzschlußauslöser) 111 und einen Überlastauslöser 110 auf. Der Schnellauslöser wirkt über ein Schaltschloß 112 auf die Hauptkontakte 113 während der Überlastauslöser 110 auf eine Hilfsschaltvorrichtung 2 mit den Hilfskontakten 95,96 und 97,98 wirkt. Die Hilfskontakte 97,98 signalisieren über die Signalisiervorrichtung S1 die Auslösung durch Überlast. Die Unterbrechung der Stromzufuhr über die Schützkontakte 114 erfolgt durch das Schütz K1 indem durch den Öffner-Kontakte 95,96 die Selbsthaltung für das Schütz K1 unterbrochen wird und das Schütz abfällt. Der Kontakt 6 symbolisiert dabei den Selbsthaltekontakt der über die Taste 5 wieder geschlossen wird. Die Taste 7 dient einer Unterbrechung der Selbsthaltung und damit der Handabschaltung des Schützes K1.Show it:

As can be seen from FIG. 1, a motor M is known to be preceded by a contactor K1 and a power switching device 1 in series. The power switching device 1 has a quick release (short-circuit release) 111 and an overload release 110. The quick release acts via a switching lock 112 on the main contacts 113, while the overload release 110 acts on an auxiliary switching device 2 with the auxiliary contacts 95, 96 and 97, 98. The auxiliary contacts 97, 98 signal the triggering by overload via the signaling device S1. The interruption of the power supply via the contactor contacts 114 takes place through the contactor K1 by the self-holding for the contactor K1 being interrupted by the break contacts 95, 96 and the contactor dropping out. The contact 6 symbolizes the self-holding contact which is closed again via the button 5. The key 7 serves to interrupt the self-holding and thus the manual shutdown of the contactor K1.

Das erfindungsgemäße Zusammenwirken der Verbindung zwischen dem Leistungsschaltgerät 1 und der Hilfsschaltvorrichtung 2 ist in Fig. 2 dargestellt. Der Auslösehebel 10, der das Wirkelement des Überlastauslösers 110 darstellt, wirkt auf einen Umschalthebel 21. Dieser ragt dabei mit dem Arm 22 durch die Öffnung 13 in der Gehäusewand 12. Der Umschalthebel 21 ist in der Hilfschaltvorrichtung 2 mittels einer Achse um den Drehpunkt 24 drehbar gelagert. Dieser Drehpunkt 24 ist um einen geringen Bereich in Bewegungsrichtung des Auslösehebels 10 verschiebbar. Dadurch kann der Anlagepunkt des Arms 22 an dem Auslösehebel 10 justiert werden. In der justierten Lage wird der Drehpunkt 24 durch bekannte Mittel, wie versiegeln, kleben oder schrauben festgesetzt werden. Der weitere Arm 23 des Umschalthebels 21 überträgt die Bewegung des Auslösehebels 10 des Überlastauslösers 110 auf ein Kippelement 25.The interaction according to the invention of the connection between the power switching device 1 and the auxiliary switching device 2 is shown in Fig. 2. The trigger lever 10, which is the active element of the overload release 110, acts on a switch lever 21. The arm 22 projects through the opening 13 in the housing wall 12. The switch lever 21 is rotatable in the auxiliary switching device 2 by means of an axis about the pivot point 24 stored. This fulcrum 24 can be moved by a small range in the direction of movement of the trigger lever 10. As a result, the point of contact of the arm 22 on the release lever 10 can be adjusted. In the adjusted position, the fulcrum 24 will be fixed by known means such as sealing, gluing or screwing. The further arm 23 of the switch lever 21 transmits the movement of the release lever 10 of the overload release 110 to a tilting element 25.

In der Darstellung in Fig. 3 ist die Wirkungsweise des Arms 23 auf das Kippelement 25 erkennbar. Das Kippelement 25 besteht aus einer Zugfeder, die einerseits in einem Widerlager 28 und andererseits an einem Kontaktträger 26 eingehängt ist, der die beweglichen Kontaktbrücken 93 und 94 und ein zwischen diesen angeordnetes Isolierstück 92 trägt. Das Isolierstück 92 dient lediglich der galvanischen Trennung zwischen den Kontaktpaaren 95/96 und 97/98. Der Kontaktträger 26 sitzt in einem Schneidenlager, das für die Pendelbewegung den Totpunkt bildet. Die Kontaktbrücken 93 und 94 pendeln aufgrund der Betätigung durch den Arm 23 sprungartig über einen Kippunkt zwischen zwei stabilen Schaltstellungen an den Festkontakten 95/96 und 97/98.The mode of action of the arm 23 on the tilting element 25 can be seen in the illustration in FIG. 3. The tilting element 25 consists of a tension spring which is suspended on the one hand in an abutment 28 and on the other hand on a contact carrier 26 which carries the movable contact bridges 93 and 94 and an insulating piece 92 arranged between them. The insulating piece 92 is used only for the electrical isolation between the contact pairs 95/96 and 97/98. The contact carrier 26 is seated in a cutting edge bearing, which forms the dead center for the pendulum movement. The contact bridges 93 and 94 oscillate suddenly due to the actuation by the arm 23 via a tipping point between two stable switching positions on the fixed contacts 95/96 and 97/98.

Die Rückstellung gegen die Bewegung des Armes 23 erfolgt durch die in Fig. 2 mit 30 bezeichnete Rückstelltaste. Die Festkontakte 97/98 sind verschiebbar angeordnet und können in Pfeilrichtung soweit verschoben werden, daß der Kontaktträger 26 nicht mehr über den Totpunkt pendelt, sondern wieder zu den Kontakten 95/96 zurückfällt. Diese Verschiebung erfolgt durch die Rückstelltaste 30, indem sie eingedrückt und bajonettartig verrastet wird.The resetting against the movement of the arm 23 is carried out by means of the reset button labeled 30 in FIG. 2. The fixed contacts 97/98 are arranged displaceably and can be displaced in the direction of the arrow to such an extent that the contact carrier 26 no longer swings over the dead center, but falls back to the contacts 95/96. This shift is carried out by the reset button 30 by being pressed in and locked in a bayonet-like manner.

In Fig. 4 und 5 ist die Rückstelltaste 30 erkennbar, die über einen Zwischenhebel 31, der unter der Wirkung einer Feder 32 steht, auf die Kontakte 97/98 wirkt. Die Kontakte 97/98 sind bei gedrückter Rückstelltaste 30 soweit in Richtung der Kontaktbrücke 94 verschoben, daß das Kippelement 25 nicht den Kippunkt überschreitet, sondern bei der Bewegung des Umschalthebels in die Ausgangsposition mittels der Kontaktbrücke 93 die Öffnerkontakte 95/96 wieder verbindet.4 and 5, the reset button 30 can be seen, which acts on the contacts 97/98 via an intermediate lever 31, which is under the action of a spring 32. The contacts are 97/98 with the reset button 30 pressed so far in the direction of the contact bridge 94 that the tilting element 25 does not exceed the tipping point, but instead connects the break contacts 95/96 again when the switch lever is moved into the starting position by means of the contact bridge 93.

Damit läßt sich die Schaltvorrichtung über einen Taster 5 wie in Fig. 1 dargestellt wieder in Einschaltstellung bringen.The switching device can thus be brought back into the switched-on position by means of a button 5, as shown in FIG. 1.
