Abstract

In order to equip an auxiliary or signal switch (which is structurally combined with the line protection circuit breaker or residual current device and is coupled to the same for operation and release) with a switching mechanism which can be influenced indirectly thereby, said switching mechanism is based on a switching lever (1) which latches over a knuckle joint on the operating side within the built-on housing (4) having the same contour, acts on the rocker contact arrangements (2, 2') and can be unlatched by an unlatching lever (8) which is operated from the side of the protective switching device, it being possible to select the auxiliary function or signal function of the built-on switch using its manually adjustable deflection with respect to the switching lever (1). <IMAGE>

Description

Die Erfindung betrifft einen Anbauschalter gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an add-on switch according to the preamble of patent claim 1.

Diesbezüglich ist aus der DE 33 04 081 C2 ein Anbauschalter bekannt, der über keine manuell zu betätigende Schaltmechanik verfügt und dessen federbelastete Wippkontaktanordnung mechanisch in direkter Kopplung von Seiten des Schutzschaltgerätes betätigt wird.In this regard, an attachment switch is known from DE 33 04 081 C2, which has no manually operated switching mechanism and whose spring-loaded rocker contact arrangement is actuated mechanically in direct coupling on the part of the protective switching device.

Des weiteren ist in der DE 31 19 165 C2 eine Baueinheit aus einem Leitungsschutzschalter sowie Hilfs- und Signalschaltern beschrieben, bei welcher die Betätigung der betreffenden Kontaktanordnungen in Verbindung mit dem Selbstschalter über eine eigene manuell zu betätigende wie auslösungsmäßig gekoppelte Schaltmechanik erfolgt.Furthermore, DE 31 19 165 C2 describes a unit consisting of a circuit breaker and auxiliary and signal switches, in which the relevant contact arrangements are actuated in conjunction with the circuit breaker by means of a separate switching mechanism which is to be actuated manually and is coupled in terms of triggering.

Bei diesen Anbauschaltern ist die Betätigung der Hilfs- und Signalkontakte mechanisch an die der Hauptkontaktanordnung des Schutzschaltgerätes gebunden. Infolge dessen kann diese feste Kopplung bei Störungen im Bereich des Anbauschalters die unbedingte Sicherheitsfunktion eines Schutzschaltgerätes beeinträchtigen. Ebenso verwehrt die kontaktseitige Verkopplung der beiden Geräte, den Anbauschalter nach einer Fehlerauslösung die Resetstellung des Schutzschaltgerätes einnehmen zu lassen.In these add-on switches, the actuation of the auxiliary and signal contacts is mechanically linked to that of the main contact arrangement of the protective switching device. As a result, this fixed coupling can impair the unconditional safety function of a protective switching device in the event of faults in the area of the add-on switch. Likewise, the coupling on the contact side of the two devices prevents the add-on switch from taking the reset position of the protective switching device after a fault has been triggered.

In Anbetracht dessen liegt der Erfindung die Aufgabe zugrunde, den Anbauschalter zur Betätigung seiner Kontaktanordnungen mit einer von Seiten des Schutzschaltgerätes indirekt angetriebenen Schaltmechanik zu versehen. Dabei soll gleichzeitig die Möglichkeit zur Wahl zwischen Hilfs- und Signalfunktion des Anbauschalters bestehen.In view of this, the invention has for its object the attachment switch for actuating its contact arrangements to be provided with a switching mechanism indirectly driven by the protective switching device. At the same time there should be the possibility to choose between auxiliary and signal function of the add-on switch.

Erfindungsgemäß wird diese Aufgabe durch die im Patentanspruch 1 genannten Merkmale gelöst.According to the invention, this object is achieved by the features mentioned in claim 1.

Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der erfindungsgemäßen Schaltmechanik sind in den Unteransprüchen 2 bis 6 angegeben. Dabei richten sich die Ansprüche 2 bis 4 auf die gegenständliche und funktionelle Ausbildung des Schalthebels und des Entklinkungshebels, sowie die an den letzteren gebundene Umstellvorrichtung. Des weiteren erfassen die Ansprüche 5 bis 6 im Bereich der Bedienungshandhabe des Anbauschalters deren Federelement in seiner Mehrfachfunktion, den an ihr gelagerten Prüfhebel zur Funktionskontrolle und ihre Kopplungsmöglichkeit mit der Handhabe des Schutzschaltgerätes.Expedient refinements and advantageous developments of the switching mechanism according to the invention are specified in subclaims 2 to 6. The claims 2 to 4 are directed to the objective and functional design of the shift lever and the unlatching lever, as well as the changeover device bound to the latter. Furthermore, claims 5 to 6 in the area of the operating handle of the attachment switch include the spring element in its multiple function, the test lever attached to it for function control and its coupling possibility with the handle of the protective switching device.

Wie aus der den anderen Abbildungen bezeichnungsmäßig übergeordneten Darstellung in Fig. 1 der Zeichnung ersichtlich ist, basiert der mit einem hier unterhalb der Zeichnungsebene gedachten Leitungsschutzschalter bedienungs- und auslösungsmäßig gekoppelte Anbauschalter in der durch vorausgegangenes Einstellen seiner Auslenkung gewählten Funktion als Hilfsschalter auf dem kreuzförmig angelegten Schalthebel 1 in der Wirkung auf die beiderseitig im Anschlußbereich des Gerätes vorgesehenen Wippkontaktanordnungen 2 und 2'. Hierbei stützt sich das zweiarmige Stellelement dieses Schalthebels 1 mit einem Arm über die Rückstellfeder 3 am Schaltergehäuse 4 ab, während der nach oben reichende andere Arm zur Bildung eines Kniehebel-Sprungwerks mit einer T-förmig ausladenden und einseitig in eine hochstehende Abwinklung auslaufenden Gleitflanke versehen ist, die eine Rastnase 5 für den tangierenden und an der federbelasteten Bedienungshandhabe 6 drehbar gelagerten Verklinkungsbügel 7 aufweist.As can be seen from the representation in Fig. 1 of the drawing, which is superordinate to the other figures, the extension switch, which is intended for operation and triggering, is coupled with a circuit breaker here below the drawing level and is based on the function selected as auxiliary switch on the cruciform lever as a result of the previous setting of its deflection 1 in effect on the rocker contact arrangements 2 and 2 'provided on both sides in the connection area of the device. Here, the two-armed actuating element of this shift lever 1 is supported by one arm via the return spring 3 on the switch housing 4, while the other arm, which extends upwards, is provided with a T-shaped protruding and flanking one-sided sliding edge to form a toggle lever spring mechanism , which has a locking lug 5 for the tangent latching bracket 7 which is rotatably mounted on the spring-loaded operating handle 6.

Um die beim Einschalten zustandegekommene Verrastung zwischen dem Schalthebel 1 und dem Verklinkungsbügel 7 im Verlauf einer durch Kurzschluß oder Überlastung verursachten Auslösung des angebauten Leitungsschutzschalters wieder aufheben zu können, ist auf Seiten des Anbauschalters der dreieckförmig angelegte Entklinkungshebel 8 vorgesehen, von dessen gehäuseseitiger Lagerstelle in Nähe der Bedienungshandhabe 6 der passive Schenkel an seinem Ende mit dem Kopplungsstift 9 durch die Gehäusewandungen in die Schaltmechanik des Leitungsschutzschalters reicht und das aktive Schenkelende die vorbezeichnete Verklinkungsstelle durch Zug aufhebend hintergreift. Dabei ist der Entklinkungshebel 8 bezüglich seiner Auslenkung im Zuge des Einschaltvorgangs durch die auf der Drehachse der Bedienungshandhabe 6 angeordnete Schenkelfeder 10 vermittels eines zentralen Drehteils 11 im Schaltergehäuse 4 veränderlich gehalten, um so durch einen besonderen Leitschenkel 12 im Zusammenwirken mit der genannten Abwinklung an der Gleitflanke des Schalthebels 1 für die Wippkontaktanordnungen 2 und 2 ' die Umschaltmöglichkeit von der Hilfs- auf die Signalfunktion zu eröffnen.In order to cancel the locking between the switching lever 1 and the latching bracket 7 that occurred when the device was switched on in the course of a tripping of the attached circuit breaker caused by a short circuit or overload can, on the side of the attachment switch, the triangular release lever 8 is provided, from the housing-side bearing near the operating handle 6 the passive leg at its end with the coupling pin 9 extends through the housing walls into the switching mechanism of the circuit breaker and the active leg end through the aforementioned latching point Reaching behind the train. The unlatching lever 8 is held variable with regard to its deflection in the course of the switching-on process by the leg spring 10 arranged on the axis of rotation of the operating handle 6 by means of a central rotating part 11 in the switch housing 4, in order to be supported by a special guide leg 12 in cooperation with the above-mentioned angling on the sliding flank the switching lever 1 for the rocker contact arrangements 2 and 2 ' to open the switchover from the auxiliary to the signal function.

Diesbezüglich steuert das Schutzschaltgerät die Kontaktanordnungen seines Anbauschalters in Hilfsfunktion entsprechend einer Betätigung des oder der Hauptkontakte, während in Signalfunktion nur ein etwaiger Fehlerfall in Form einer Kurzschluß-, Überlastungs- oder Fehlerstromauslösung auf Seiten des Schutzschaltgerätes angezeigt wird. Für beide Funktionsarten wird durch Betätigen der Bedienungshandhabe 6 - und in mechanischer Kopplung mit dem Schutzschaltgerät - der druckfederbelastete Schalthebel 1 in der Wirkung auf die Wippkontaktanordnungen 2 und 2' des Anbauschalters kniegelenkartig in die stabile Einschaltstellung bewegt. Hierbei verstellt sich zur gleichen Zeit der mit der Auslösemechanik des Schutzschaltgerätes gehäuseübergreifend gekoppelte Entklinkungshebel 8 bis an den inmitten des Gehäuses 4 durch das Drehteil 11 definiert verstellbar vorgesehenen Anschlag und hintergreift dabei eine Auslösung vorbereitend die gebildete Verklinkungsstelle 1/7. Bei einer manuellen Ausschaltung beider Geräte kehrt sich dieser Vorgang kinematisch um.In this regard, the protective switching device controls the contact arrangements of its attachment switch in an auxiliary function according to an actuation of the main contact or contacts, while in the signal function only a possible fault in the form of a short-circuit, overload or fault current trip is indicated on the part of the protective switching device. For both types of function, by actuating the operating handle 6 - and in mechanical coupling with the protective switching device - the pressure spring-loaded switching lever 1 is moved in the effect on the rocker contact arrangements 2 and 2 'of the add-on switch in the stable switch-on position. At the same time, the unlatching lever 8, which is coupled to the triggering mechanism of the protective switching device across the housing, moves up to the stop provided in the housing 4, which is defined by the rotating part 11, and thereby engages a release in preparation for the latching point 1/7 formed. If both devices are switched off manually, this process is reversed kinematically.

Bei einer fehlerverursachten Auslösung durch das Schutzschaltgerät verstellt sich in dessen Schaltmechanik der dortige Auslösehebel nach oben und nimmt auf Seiten des Anbauschalters den am Entklinkungshebel 8 angebrachten Kopplungsstift 9 nach oben bzw. gegen den Druck der handhabenseitigen Schenkelfeder 10 in die Ausschaltstellung mit. Dabei wird durch den Zugschenkel des Entklinkungshebels 8 das Abstützen des Verklinkungsbügels 7 der Bedienungshandhabe 6 an der Rastnase 5 des Schalthebels 1 aufgehoben, welcher sich daraufhin mitsamt den Wippkontaktanordnungen 2 und 2' unter Wirkung der Rückstellfeder 3 gegen einen Gehäuseanschlag in die Ausschaltstellung zurückbewegt. Im Zuge dessen fängt sich der federbelastete Verklinkungsbügel 7 lose vor der Abwinklung der Gleitflanke des Schalthebels 1 und ermöglicht auf diese Weise der Bedienungshandhabe 6 gemeinsam mit der des Schutzschaltgerätes die von dem letzteren vorgegebene Resetstellung einzunehmen. Dabei ist auch auf Seiten der Schaltmechanik des Anbauschalters die Wiedereinschaltung nur nach vorausgegangener Ausschaltbetätigung möglich.If the protective switching device triggers an error, the triggering mechanism there moves upwards in the switching mechanism and, on the side of the attachment switch, takes the coupling pin 9 attached to the unlatching lever 8 upwards or against the pressure of the leg spring 10 on the handling side into the switched-off position. The pull leg of the unlatching lever 8 removes the support of the latching bracket 7 of the operating handle 6 on the latching lug 5 of the switching lever 1, which then moves back together with the rocker contact arrangements 2 and 2 'under the action of the return spring 3 against a housing stop into the switched-off position. In the course of this, the spring-loaded latching bracket 7 catches loosely before the sliding flank of the switching lever 1 is angled, and in this way enables the operating handle 6, together with that of the protective switching device, to assume the reset position specified by the latter. On the side of the switching mechanism of the add-on switch, it is only possible to switch on again after the previous switch-off operation.

Für die Funktion des Anbauschalters als Signalschalter zur Anzeige einer Fehlerauslösung auf Seiten des Schutzschaltgeräte: ändert sich in seiner Schaltmechanik lediglich der Auslenkungsgrad für den federbelasteten Entklinkungshebel 8 in Relation zu dem Schalthebel 1. Dies geschieht von außen her durch manuelles Verstellen des dem zentralgelegenen Drehteil 11 angeformten Anschlagnockens aus der Position zur Begrenzung der Auslenkung des Entklinkungshebels 8 in eine solche zu deren Erweiterung. Dementsprechend gelangt der dem Entklinkungshebel 8 besonders angeformte Leitschenkel 12 nunmehr in den Sperrbereich der Gleitflankenabwinklung des Schalthebels 1, womit sich bei manuellem Ausschalten der Entklinkungshebel 8 auf dem Schalthebel 1 abstützt und die Betätigung der Wippkontaktanordnungen 2 und 2' verhindert, wobei die Bedienungshandhabe 6 - zusammen mit der des Schutzschaltgerätes - in die Ausschaltstellung zurückschwenkt. Danach verläßt der Schalthebel 1 des Anbauschalters diese Position nur durch erneutes Einschalten beider Geräte.For the function of the add-on switch as a signal switch to indicate a fault triggering on the part of the protective switching devices: only the degree of deflection for the spring-loaded release lever 8 changes in relation to the switching lever 1 in its switching mechanism. This is done from the outside by manually adjusting the central rotating part 11 Stop cam from the position to limit the deflection of the unlatching lever 8 in such a way to expand it. Accordingly, the guide leg 12, which is specially molded onto the unlatching lever 8, now comes into the blocking region of the sliding flank angled portion of the switching lever 1, which, when the unlatching lever 8 is switched off manually, is supported on the switching lever 1 and prevents the actuation of the rocker contact arrangements 2 and 2 ', the operating handle 6 - together with that of the protective switching device - swings back into the switch-off position. Then the shift lever 1 of the Extension switch this position only by switching both devices on again.

Für den Vorgang des Prüfens der ordnungsgemäßen Funktion des Hilfs- und Signalschalters empfiehlt sich die vorherige Entkopplung der Bedienungshandhaben beider Geräte in der Einschaltposition. Danach bewirkt ein in den Gehäusedurchbruch des Anbauschalters neben der Bedienungshandhabe 6 eingeführtes und gegen den darunter gelegenen Arm des Prüfhebels 13 gedrücktes Werkzeug, daß dessen anderer Hebelarm den Kopplungsstift 9 des Entklinkungshebels 8 nach oben verstellt und den Schaltmechanismus des Anbauschalters in vorbeschriebener Weise auslöst. Hierfür kann das zu betätigende Ende des Prüfhebels 13 einen innengelegenen Gehäuseansatz elastisch übergreifen. Diese Maßnahme bewirkt, daß der einmal betätigte Prüfhebel 13 nicht von selbst in seine Ausgangsstellung zurückkehren kann, sondern durch einen (nicht dargestellten) Nocken an der dazu betätigten Bedienungshandhabe 6 zurückgestellt werden muß.For the process of checking the correct function of the auxiliary and signal switch, it is advisable to uncouple the operating handles of both devices in the switch-on position. Then causes in the housing opening of the extension switch next to the operating handle 6 and pressed against the underlying arm of the test lever 13 tool that its other lever arm adjusts the coupling pin 9 of the release lever 8 upwards and triggers the switching mechanism of the attachment switch in the manner described above. For this purpose, the end of the test lever 13 to be actuated can elastically overlap an internal housing attachment. This measure has the effect that the test lever 13, once actuated, cannot return to its starting position by itself, but must be reset by a cam (not shown) on the operating handle 6 actuated for this purpose.
