Definitions
- the invention relates to a full-circuit breaker with a circuit breaker and an attachable thereto fault current component according to the preamble of claim 1.
- Such full-circuit breakers with fault current components and circuit breakers which form a circuit breaker as a whole, which interrupts a current path to be monitored both in a short circuit occurring, as well as a thermal overcurrent and also in a fault current occurring, are known in principle.
- the two devices, the circuit breaker and the fault current component are coupled together such that when the fault current component of the circuit breaker switches off when the circuit breaker response but the fault current component remains in tripping ready position, unless the short circuit or overcurrent was connected to a fault current.
- Such full-circuit breaker thus serve at the same time the protection of the monitored line network against short circuit and overload, such as the prevention of electrical accidents due to line defects and the like.
- the DE 44 13 418 A1 shows a generic full-circuit breaker with a circuit breaker and an attachable thereto residual current protection part.
- the trigger element of the switching mechanism of the residual current protection part is coupled to a coupling element with the circuit breaker.
- the coupling element cooperates with the release lever of the circuit breaker in such a way that it is always the release lever of the circuit breaker in the direction Entklinkung the Verklinkungsstelle of the switching mechanism at a tripping of the residual current protection part of the circuit breaker.
- the residual current protection part and the circuit breaker are connected to each other via a slide.
- the slider in cooperation with a lever mechanism in the fault current component, ensures that the fault current component can be actuated, even if the circuit breaker has tripped, for example because of an overcurrent.
- the switching mechanism of the fault current component remains in its tripped position until it is reset by manual operation of the switch knob of the fault current component. Only with the manual reset of the switching mechanism of the fault current component, the coupling element returns to a position in which the action of the release lever of the circuit breaker is released in the direction Entklinkung the Verklinkungsstelle the switching mechanism of the circuit breaker and therefore the Verklinkungsstelle the switching mechanism of the circuit breaker can be latched again.
- the switching knob of the fault current component Due to the mechanical leverage in the fault current component, which transmits the rotational movement of the switch knob on a sliding movement of the coupling element, a certain flow of the switching knob of the fault current component is inevitably required. That is, the switching knob of the fault current component must first be rotated by a certain angle in the direction of the closed position, and only then does the coupling element get into such a position in which it allows the Verklinkungsstelle the circuit breaker Wiederverklinken.
- the fault current component must first be turned on, then only the switching of the circuit breaker is possible.
- the first switching toggle of the fault current component and the second switching toggle of the circuit breaker are coupled by means of a second coupling element, wherein the second coupling element acts on the first switching toggle against the second switching toggle in the direction of its closed position by the predeterminable advance angle.
- a very advantageous embodiment is given by a generic full-circuit breaker in which the first switching mechanism by means of a first coupling element with a release lever of the second switching mechanism is coupled such that when the first switching mechanism of the fault current component goes into its EntklinkungsSullivan and the first switching knob in its off position pivoted about the first coupling element and the release lever a Verklinkungsstelle the second switching mechanism is held in its Entklinkungslage.
- This embodiment is further characterized in that the second coupling element in a forced shipment from a first, corresponding to the switch-off position of the second switch knob position in a second, corresponding to the closed position of the second switch knob position, initially applied only to the first switching knob of the fault current component and pivoting this is pivoted by a predeterminable lead angle before it also acts on the second switching knob of the circuit breaker pivoting.
- a further advantageous embodiment is characterized in that the first switching knob is pivoted and held by the second coupling element with respect to its switch-off at least by the lead angle against the second switch knob and in the direction of its closed position.
- the lead angle is such that the leading pivoting of the first switching knob sets the first switching mechanism of the fault current component in such a state in which releases the release lever of the circuit breaker via the first coupling element and the Verklinkungsstelle the second switching mechanism thereby verklinkbar is.
- a full-circuit breaker according to the invention has the advantage that it can be forcibly restarted via a motor connected to it remotely controlled.
- a forced restarting a circuit breaker on a queued switching motor is known in principle. Without the inventive design of a full circuit breaker, however, an engine connected to the remote drive via its motor arm could only drive either the circuit breaker or only the fault current component to reconnect. Turning on the circuit breaker without previously turning on the fault current component would not work as stated above. Likewise, after switching on the fault current component at the same time the circuit breaker would be turned on, because this requires it in the known in the art devices of their own operation of the switch knob of the circuit breaker.

- This is composed of a structurally-functional union of a single-pole disconnecting circuit breaker 2 with a fault current component 4, wherein the to be combined switch elements 2, 4 are each designed in a narrow construction and with the same housing contour.
- the fault current component 4 is, in principle, a residual current circuit breaker without a contact point and without a connecting conductor. However, it includes the trip and switch mechanism as well as any residual current circuit breaker used as a single switch element.
- it therefore comprises a first switching mechanism 8 which is switched on or off manually from the outside via a first switching knob 6, which interacts with the first switching mechanism 8 along a line of action 20 can be.
- the switching mechanism 8 in the schematic example shown here should also functionally include the triggering mechanism in addition to the mechanical parts such as Verklinkungsstelle and lever mechanism, which for example in a known manner a transducer with a secondary winding and a cooperating magnetic release after the hinged armature - or the Schlagankerkal includes.
- the switching and triggering mechanism of the fault current component 4 and also of the circuit breaker 2 should not be further described here, since they are known in principle.
- the fault current component 4 When a fault current occurs, the fault current component 4 thus does not automatically interrupt the circuit to be monitored. Rather, to break the circuit of the circuit breaker 2 is used, the switching mechanism 14 via a line of action 24, the contact point 26 opens or closes in a current path 28, wherein the current path 28 is connected between an input terminal 30 and an output terminal 32 in the circuit to be monitored.

- the second switching mechanism 14 in the circuit breaker 2 comprises a release lever 12. If this is held in its trigger position, it prevents a latching also present in the second switching mechanism 14 Verklinkungsstelle (this is not explicitly drawn here), which has the consequence that the second switching mechanism 14 via the second switch knob 16 can not be turned on.
- the first switching mechanism 8 of the fault current component 2 is coupled to the triggering lever 12 via a first coupling element 10.
- the first coupling element 10 may be a slider or a lever which passes through the common broad sides of the circuit breaker 2 and the fault current component 4 at a designated location and through openings provided in the broad sides.
- the two switching toggle 6, 16 of the fault current component 4 and the residual current circuit breaker 2 are mechanically coupled to each other via a second coupling element 18.

- the second coupling element 18 has been moved a little way in the direction of arrow P to the right on its Einschaltlage. It is located in an intermediate position between the switch - on and switch - off position.

- the first switching knob 6 of the fault current component 4 is acted upon pivoting by the second coupling element in the direction of its closed position and a lead angle ⁇ spent in the direction of its closed position.
- the lead angle ⁇ is sufficiently large to enable the first switching mechanism 8 in such a state in which it releases the release lever 12 via the first coupling element 10.
- the Verklinkungsstelle the second switching mechanism 14 is now verklinkbar again. However, since the second switching knob 16 of the circuit breaker 2 is still in its off position, the latching of the second switching mechanism 14 is not yet taking place.
- Typical lead angles are values between 9 ° and 40 °, depending on the specific mechanical design of the derailleurs and the lever mechanisms.

This ensures that, if in the event of a fault current trip of the rear derailleur 8 of the fault current component 4 via the first coupling element 10, the switching mechanism 141 of the fault current component 4 directly adjacent circuit breaker 201 is forcibly triggered, at the same time the rear deraille 142 and 143 of the circuit breaker 201 stringed circuit breaker 202 and 203 are triggered.

Description
Die Erfindung betrifft einen Voll-Schutzschalter mit einem Leitungsschutzschalter und einem daran anbaubaren Fehlerstrombauteil gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a full-circuit breaker with a circuit breaker and an attachable thereto fault current component according to the preamble of
Solche Voll-Schutzschalter mit Fehlerstrombauteilen und Leitungsschutzschaltern, die in der Gesamtheit einen Schutzschalter bilden, der einen zu überwachenden Strompfad sowohl bei einem auftretenden Kurzschluss, als auch bei einem thermischen Überstrom und weiterhin auch bei einem auftretenden Fehlerstrom unterbricht, sind im Prinzip bekannt. Die beiden Geräte, der Leitungsschutzschalter und das Fehlerstrombauteil, werden miteinander derart gekoppelt, dass bei Auslösung des Fehlerstrombauteils der Leitungsschutzschalter ausschaltet, bei Ansprechen des Leitungsschutzschalters aber das Fehlerstrombauteil in auslösebereiter Stellung verbleibt, sofern nicht der Kurzschluss oder Überstrom mit einem Fehlerstrom verbunden war. Derartige Voll-Schutzschalter dienen somit zur gleichen Zeit dem Schutz des zu überwachenden Leitungsnetzes gegen Kurzschluss und Überlastung, wie zur Verhütung von Elektrounfällen durch Leitungsdefekte und dergleichen.Such full-circuit breakers with fault current components and circuit breakers, which form a circuit breaker as a whole, which interrupts a current path to be monitored both in a short circuit occurring, as well as a thermal overcurrent and also in a fault current occurring, are known in principle. The two devices, the circuit breaker and the fault current component, are coupled together such that when the fault current component of the circuit breaker switches off when the circuit breaker response but the fault current component remains in tripping ready position, unless the short circuit or overcurrent was connected to a fault current. Such full-circuit breaker thus serve at the same time the protection of the monitored line network against short circuit and overload, such as the prevention of electrical accidents due to line defects and the like.
Die
Wenn nach einem Ansprechen des Fehlerstrombauteils die Ursache hierfür, also das Auftreten eines Fehlerstroms wieder abgeklungen ist, dann verbleibt das Schaltschloss des Fehlerstrombauteils in seiner ausgelösten Stellung, solange, bis es durch manuelle Betätigung des Schaltknebels des Fehlerstrombauteils zurückgesetzt wird. Erst bei dem manuellen Rücksetzen des Schaltschlosses des Fehlerstrombauteils gelangt das Koppelelement wieder in eine Lage, in der die Beaufschlagung des Auslösehebels des Leitungsschutzschalters in Richtung Entklinkung der Verklinkungsstelle des Schaltschlosses des Leitungsschutzschalters aufgehoben ist und daher die Verklinkungsstelle des Schaltschlosses des Leitungsschutzschalters wieder verklinkt werden kann.If after a response of the fault current component, the cause, ie the occurrence of a fault current has subsided again, then the switching mechanism of the fault current component remains in its tripped position until it is reset by manual operation of the switch knob of the fault current component. Only with the manual reset of the switching mechanism of the fault current component, the coupling element returns to a position in which the action of the release lever of the circuit breaker is released in the direction Entklinkung the Verklinkungsstelle the switching mechanism of the circuit breaker and therefore the Verklinkungsstelle the switching mechanism of the circuit breaker can be latched again.
Dann erst kann der Leitungsschutzschalter über seinen Schaltknebel manuell wieder eingeschaltet werden.Only then can the circuit breaker be manually switched on again via its switch knob.
Durch die mechanische Hebelübersetzung in dem Fehlerstrombauteil, die die Drehbewegung des Schaltknebels auf eine Verschiebebewegung des Koppelelementes überträgt, ist zwangsläufig ein gewisser Vorlauf des Schaltknebels des Fehlerstrombauteils erforderlich. Das heißt, der Schaltknebel des Fehlerstrombauteils muss erst um einen bestimmten Winkel in Richtung auf die Einschaltstellung hin verdreht werden, und erst dann gelangt das Koppelelement in eine solche Lage, in der es ein Wiederverklinken der Verklinkungsstelle des Leitungsschutzschalters erlaubt.Due to the mechanical leverage in the fault current component, which transmits the rotational movement of the switch knob on a sliding movement of the coupling element, a certain flow of the switching knob of the fault current component is inevitably required. That is, the switching knob of the fault current component must first be rotated by a certain angle in the direction of the closed position, and only then does the coupling element get into such a position in which it allows the Verklinkungsstelle the circuit breaker Wiederverklinken.
Wenn nach dem Auslösen des Fehlerstrombauteils und dem dadurch erzwungenen Ausschalten des Leitungsschutzschalters letzterer wieder eingeschaltet werden soll, muss zunächst das Fehlerstrombauteil eingeschaltet werden, dann erst ist ein Einschalten des Leitungsschutzschalters möglich.If after the triggering of the fault current component and the forced shutdown of the circuit breaker the latter is to be turned on again, the fault current component must first be turned on, then only the switching of the circuit breaker is possible.
Es ist die Aufgabe der vorliegenden Erfindung, ein vereinfachtes und gemeinsames Wiedereinschalten des Fehlerstrombauteils und des Leitungsschutzschalters bei einem Voll-Schutzschalter zu ermöglichen.It is the object of the present invention to enable a simplified and common reconnection of the fault current component and the circuit breaker in a full circuit breaker.
Die Aufgabe wird gelöst durch einen gattungsgemäßen Voll-Schutzschalter mit den kennzeichnenden Merkmalen des Anspruchs 1.The object is achieved by a generic full-circuit breaker with the characterizing features of
Erfindungsgemäß also sind der erste Schaltknebel des Fehlerstrombauteils und der zweite Schaltknebel des Leitungsschutzschalters mittels eines zweiten Koppelelementes gekoppelt , wobei das zweite Koppelelement den ersten Schaltknebel gegen den zweiten Schaltknebel in Richtung auf seine Einschaltstellung hin um den vorgebbaren Vorlaufwinkel verschwenkend beaufschlagt.Thus, according to the invention, the first switching toggle of the fault current component and the second switching toggle of the circuit breaker are coupled by means of a second coupling element, wherein the second coupling element acts on the first switching toggle against the second switching toggle in the direction of its closed position by the predeterminable advance angle.
Eine sehr vorteilöhafte Ausführungsform ist durch einen gattungsgemäßen Voll-Schutzschalter gegeben, bei dem das erste Schaltschloss mittels eines ersten Koppelelementes mit einem Auslösehebel des zweiten Schaltschlosses derart koppelbar ist, dass, wenn das erste Schaltschloss des Fehlerstrombauteilsin seinen Entklinkungszustand übergeht und der erste Schaltknebel in seine Ausschaltstellung verschwenkt, über das erste Koppelelement und den Auslösehebel eine Verklinkungsstelle des zweiten Schaltschlosses in ihrer Entklinkungslage gehalten ist. Diese Ausführungsform ist weiterhin dadurch gekennzeichnet, dass das zweite Koppelelement bei einer erzwungenen Verbringung aus einer ersten, mit der Ausschaltstellung des zweiten Schaltknebels korrespondierenden Lage in eine zweite, mit der Einschaltstellung des zweiten Schaltknebels korrespondierenden Lage, zunächst nur den ersten Schaltknebel des Fehlerstrombauteils verschwenkend beaufschlagt und diesen dadurch um einen vorgebbaren Vorlaufwinkel verschwenkt, bevor es auch den zweiten Schaltknebel des Leitungsschutzschalters verschwenkend beaufschlagt.A very advantageous embodiment is given by a generic full-circuit breaker in which the first switching mechanism by means of a first coupling element with a release lever of the second switching mechanism is coupled such that when the first switching mechanism of the fault current component goes into its Entklinkungszustand and the first switching knob in its off position pivoted about the first coupling element and the release lever a Verklinkungsstelle the second switching mechanism is held in its Entklinkungslage. This embodiment is further characterized in that the second coupling element in a forced shipment from a first, corresponding to the switch-off position of the second switch knob position in a second, corresponding to the closed position of the second switch knob position, initially applied only to the first switching knob of the fault current component and pivoting this is pivoted by a predeterminable lead angle before it also acts on the second switching knob of the circuit breaker pivoting.
Eine weitere vorteilhafte Ausführungsform ist dadurch gekennzeichnet, dass der erste Schaltknebel durch das zweite Koppelelement gegenüber seiner Ausschaltstellung wenigstens um den Vorlaufwinkel gegen den zweiten Schaltknebel und in Richtung auf seine Einschaltstellung hin verschwenkt und gehalten ist.A further advantageous embodiment is characterized in that the first switching knob is pivoted and held by the second coupling element with respect to its switch-off at least by the lead angle against the second switch knob and in the direction of its closed position.
Dabei ist in einer bevorzugten Ausführungsform der Vorlaufwinkel so bemessen, dass das vorlaufende Verschwenken des ersten Schaltknebels das erste Schaltschloss des Fehlerstrombauteils in einen solchen Zustand versetzt, in dem dieses über das erste Koppelelement den Auslösehebel des Leitungsschutzschalters freigibt und die Verklinkungsstelle des zweiten Schaltschlosses dadurch wieder verklinkbar ist. Insgesamt ist somit ein gemeinsames Einschalten des Fehlerstrombauteils und des Leitungsschutzschalters durch Betätigen eines einzigen Bedienelementes ermöglicht.In this case, in a preferred embodiment, the lead angle is such that the leading pivoting of the first switching knob sets the first switching mechanism of the fault current component in such a state in which releases the release lever of the circuit breaker via the first coupling element and the Verklinkungsstelle the second switching mechanism thereby verklinkbar is. Overall is thus enabling a common turning on the fault current component and the circuit breaker by pressing a single control element.
Insbesondere bietet ein erfindungsgemäßer Voll-Schutzschalter den Vorteil, dass er über einen an ihn angereihten Motor ferngesteuert zwangsweise wieder eingeschaltet werden kann. Ein zwangsweises Wiedereinschalten eines Leitungsschutzschalters über einen angereihten Schaltmotor ist zwar im Prinzip bekannt. Ohne die erfindungsgemäße Ausgestaltung eines Voll-Schutzschalters könnte jedoch ein zum Fernantrieb angereihter Motor über seinen Motorarm nur entweder den Leitungsschutzschalter oder nur das Fehlerstrombauteil zum Wiedereinschalten antreiben. Ein Einschalten des Leitungsschutzschalters ohne vorheriges Einschalten des Fehlerstrombauteils würde, wie oben dargelegt, nicht funktionieren. Ebenso wenig würde nach dem Einschalten des Fehlerstrombauteils gleichzeitig der Leitungsschutzschalter eingeschaltet werden, denn dazu bedarf es bei den im stand der Technik bekannten Geräten einer eigenen Betätigung des Schaltknebels des Leitungsschutzschalters. Erst dadurch, dass in Folge der erfindungsgemäßen Lehre ein gemeinsames Einschalten des Fehlerstrombauteils und des Leitungsschutzschalters durch ein einziges Bedienelemente möglich ist, kann ein solcher erfindungsgemäßer Voll-Schutzschalter durch einen daran angereihten Motor ferngesteuert gemeinsam zwangsweise wieder eingeschaltet werden.In particular, a full-circuit breaker according to the invention has the advantage that it can be forcibly restarted via a motor connected to it remotely controlled. A forced restarting a circuit breaker on a queued switching motor is known in principle. Without the inventive design of a full circuit breaker, however, an engine connected to the remote drive via its motor arm could only drive either the circuit breaker or only the fault current component to reconnect. Turning on the circuit breaker without previously turning on the fault current component would not work as stated above. Likewise, after switching on the fault current component at the same time the circuit breaker would be turned on, because this requires it in the known in the art devices of their own operation of the switch knob of the circuit breaker. Only in that, as a result of the teaching of the invention, a common switching of the fault current component and the circuit breaker by a single controls is possible, such a full-breaker according to the invention can be remotely controlled jointly forcibly again by a bayed engine.

Bei Auftreten eines Fehlerstroms kann das Fehlerstrombauteil 4 somit nicht selbsttätig den zu überwachenden Stromkreis unterbrechen. Vielmehr wird zum Unterbrechen des Stromkreises der Leitungsschutzschalter 2 verwendet, dessen Schaltschloss 14 über eine Wirklinie 24 die Kontaktstelle 26 in einem Strompfad 28 öffnet oder schließt, wobei der Strompfad 28 zwischen einer Eingangsklemme 30 und einer Ausgangsklemme 32 in den zu überwachenden Stromkreis hineingeschaltet wird. Das Schaltschloss 14 des Leitungsschutzschalters kann von außen über einen zweiten Schaltknebel 16 manuell betätigt werden und wirkt dann entlang einer Wirklinie 22 mit dem Schaltschloss 14 zusammen. In der schematischen Darstellung gemäß der
Das zweite Schaltschloss 14 in dem Leitungsschutzschalter 2 umfasst einen Auslösehebel 12. Wenn dieser in seiner Auslöserstellung gehalten ist, verhindert er ein Verklinken der ebenfalls in dem zweiten Schaltschloss 14 vorhandenen Verklinkungsstelle (diese ist hier nicht explizit gezeichnet), was zur Folge hat, dass das zweite Schaltschloss 14 über den zweiten Schaltknebel 16 nicht eingeschaltet werden kann.The
Das erste Schaltschloss 8 des Fehlerstrombauteils 2 ist über ein erstes Koppelelement 10 mit dem Auslösehebel 12 gekoppelt. Das erste Koppelelement 10 kann ein Schieber oder ein Hebel sein, der die gemeinsamen Breitseiten des Leitungsschutzschalters 2 und des Fehlerstrombauteils 4 an einer dafür vorgesehenen Stelle und durch dafür vorgesehene Öffnungen in den Breitseiten durchgreift.The
Die beiden Schaltknebel 6, 16 des Fehlerstrombauteils 4 beziehungsweise des Fehlerstromschutzschalters 2 sind über ein zweites Koppelelement 18 miteinander mechanisch gekoppelt.The two switching

Typische Vorlaufwinkel liegen, je nach der konkreten mechanischen Konstruktion der Schaltwerke und der Hebelmechanismen bei Werten im Bereich zwischen 9° und 40°.Typical lead angles are values between 9 ° and 40 °, depending on the specific mechanical design of the derailleurs and the lever mechanisms.
Bei einer weiteren Bewegung des zweiten Koppelelementes 18 über die Zwischenlage hinaus in die Einschaltlage gemäß
Insgesamt ist somit durch die erzwungene Verbringung des zweiten Koppelelementes 18 aus seiner Ausschaltlage in seine Einschaltlage ein gemeinsames Einschalten des Leitungsschutzschalters 2 und des Fehlerstrombauteils 4 durch Bewegung nur eines einzigen Koppelelementes ermöglicht worden. Ohne die erfindungsgemäße Kopplung der beiden Schaltknebel 6, 16 mit dem zweiten Koppelelement 18 hätte zuerst der erste Schaltknebel 6 des Fehlerstrombauteils in seine Einschaltposition gebracht werden müssen, und erst danach hätte der Leitungsschutzschalter 2 eingeschaltet werden können.Overall, therefore, by the forced shipment of the
Es werden nun die
Damit die drei Polstrompfade auch wieder gemeinsam eingeschaltet werden können, sind die drei Schaltknebel 161, 162, 163 der drei Leitungsschutzschalter 201, 202, 203 über ein drittes Koppelelement 38 miteinander verbunden. Diese Verbindung dreier aneinander gereihter einpoliger Leitungsschutzschalter um einen dreipoligen Schutz zu erreichen ist im Prinzip bekannt.So that the three pole current paths can also be switched on again together, the three switching
Um zu einem Voll-Schutzschalter zu gelangen, der eine baulich - funktionelle Vereinigung eines dreipolig abschaltenden Verbundes dreier einpoliger Leitungsschutzschalter mit einem Fehlerstrombauteil 4 realisiert, ist der erste Schaltknebel 6 des Fehlerstrombauteils 4 über ein zweites Koppelelement 18 mit dem dritten Koppelelement 38, welches die drei Schaltknebel 161, 162, 163 miteinander verbindet, gekoppelt. Die Art und funktionelle Ausgestaltung dieser Kopplung ist entsprechend der oben bezüglich der Ausführungsform gemäß

Bei den bisher beschriebenen Ausführungsformen war immer davon ausgegangen worden, dass der erste Schaltknebel 6 des Fehlerstrombauteils 4 bei einer Auslösung desselben vollständig in seiner Ausschaltlage verschwenkt wird, welches jeweils der in den Teilzeichnungen a der
Bisher wurde das Fehlerstrombauteil 4 als ein wie ein Fehlerstromschutzschalter wirkendes Bauteil beschrieben, dass jedoch nicht über die Möglichkeiten verfügt, direkt einen Strompfad zu unterbrechen, das also nicht über eine Kontaktstelle mit den entsprechenden Anschlussleitern, den festen und beweglichen Kontaktstücken und den Kontakthebeln verfügt. Selbstverständlich könnte jedoch auch ein als selbstständiger Fehlerstromschutzschalter verwendbares Bauteil, das dann auch noch über eigene Möglichkeiten der Strompfad-Unterbrechung verfügt, es als Fehlerstrombauteil in einem erfindungsgemäßen Voll-Schutzschalter verwendet werden.So far, the fault
Es werde jetzt die
An der vorderen Frontseite 81 des Fehlerstrombauteils 84 und auch des dahinterliegenden Leitungsschutzschalters befindet sich eine domartige Vorwölbung 88, welche Teile des mechanischen Schaltwerks umfasst und entlang deren gewölbten Außenfläche der erste Schaltknebel 6 des Fehlerstrombauteils und der zweite Schaltknebel des Leitungsschutzschalters verschwenkt werden können. In der Ausschaltstellung, welche in der
Die beiden Schaltknebel 6, 16 sind mit einem zweiten Koppelelement 18 gekoppelt. Das Koppelelement 18 hat in etwa die Gestalt einer Schiene mit einem U-förmigen Profil. Je ein Schenkel des Koppelelementes 18 liegt in der Ausschaltstellung gemäß
Die in der
An dem Koppelelement 18 könnte auch beispielsweise ein Schaltmotor mit seiner Schaltwelle angreifen und die Verschwenkung des Koppelelements 18 im Uhrzeigersinn bewirken. Dies entspräche dann funktional einer Ausführungsform gemäß der
Die
An der äußeren linken Breitseite des Leitungsschutzschalters 201 ist ein Fehlerstrombauteil 4 angereiht und mit den Leitungsschutzschaltern 201, 202, 203 funktional gekoppelt wie oben beschrieben. Das Fehlerstrombauteil 4 wird in diesem Zusammenhang in der Fachsprache auch als DDA bezeichnet. An der äußeren rechten Breitseite des Leitungsschutzschalters 203 ist ein Schaltmotor 40 angereiht. Seine Antriebswelle ist mit einem vierten Koppelelement 381 mit dem LS-Verbinder 183 gekoppelt. Das Einund Ausschalten der Leitungsschutzschalter 201, 202, 203 und des DDA 4 erfolgt hier, wie im Prinzip heute allgemein üblich, durch Verschwenken der Schaltgriffe um ihre jeweilige Achse, so dass die Schaltgriffe beim Schalten einen Winkelbereich überfahren.On the outer left broad side of the
Anhand der
Bei dem LS-Verbinder 183 handelt es sich im Prinzip um eine längserstreckte Schiene, vorteilhafterweise aus Kunststoff, welche ein etwa U-förmiges Querschnittsprofil aufweist. In der montierten Position, welche in der
Der erste Schaltknebel 6 des Fehlerstrombauteils weist eine Nase 7 auf, welche parallel zum Verlauf des LS-Verbinders 183 vorspringt und an einer Koppelstelle 9 an diesem anliegt. Das vierte Koppelelement 381 ist mit dem LS-Verbinder 183 verbunden.The
Wenn nun der Schaltmotor 40 das vierte Koppelelement 381 in Richtung des mit "Ein" bezeichneten Pfeils verschwenkt, so wird dadurch gleichzeitig der LS-Verbinder 183 in dieselbe Richtung verschwenkt. Wegen der Kopplung an der Koppelstelle 9 wird sofort der erste Schaltknebel 6 des DDA 4 ebenfalls in Einschaltrichtung verschwenkt. Die Schaltknebel 161, 162, 163 bleiben jedoch noch in ihrer Ausschaltstellung, denn wegen des Freiraums a kommt der zweite Schenkel 111 erst dann in Kontakt mit den Schaltknebeln 161, 162, 163, wenn der LS-Verbinder 183 um einen dem Freiraum α entsprechenden Verschiebeweg oder Schwenkwinkel verschwenkt wurde. Der Freiraum α realisiert somit den Vorlauf, der notwendig ist, damit der DDA ein Wiedereinschalten der Leitungsschutzschalter 201, 202, 203 gestatten kann, wie oben beschrieben. Somit ist ein gemeinsames Einschalten aller drei Leitungsschutzschalter oder Pole 201, 202, 203 und des DDA 4 durch den Schaltmotor ermöglicht.Now, if the switching
Im eingeschalteten Zustand erlaubt der Freiraum α, dass bei Auslösen eines einzelnen oder aller drei Leitungsschutzschalter oder Pole ohne Auslösen des DDA, etwa bedingt durch einen thermischen Überstrom, welcher den DDA ja nicht auslösen würde, die Schaltknebel 161, 162, 163 dennoch in ihre Ausschaltstellung verschwenken können. Denn durch den inneren mechanischen Aufbau der Leitungsschutzschalter 201, 202, 203 kann die Verklinkungsstelle des Schaltwerkes eines Leitungsschutzschalters nach einem Auslösen nur dann wieder verklinkt werden, wenn der Schaltknebel sich in seiner Ausschaltstellung befindet. Nur dann ist ein Wiedereinschalten des Leitungsschutzschalters möglich. Durch die erfindungsgemäß gestaltete Kopplung wird eine ganz normale Funktion der Leitungsschutzschalter unabhängig von dem DDA ermöglicht, wie auch die Zwangsauslösung durch den DDA mit anschließendem gemeinsamen Wiedereinschalten durch den Schaltmotor 40.In the on state allows the free space α that when triggering a single or all three circuit breakers or poles without triggering the DDA, such as caused by a thermal overcurrent, which would not trigger the DDA, the switching
Wenn hingegen aufgrund eines Fehlerstrom der DDA anspricht und sein erster Schaltknebel 6 sich in die Ausschaltstellung, gekennzeichnet durch den mit "Aus" bezeichneten Pfeil, verschwenkt, dann wird durch die Kopplung an der Koppelstelle 9 der LS-Verbinder 183 sofort in die Ausschaltposition verschwenkt und mit ihm werden wegen des Anliegens des ersten Schenkels 112 an den Schaltknebeln 161, 162, 163 auch diese sofort gemeinsam in ihre Ausschaltstellung verbracht.If, however, responsive due to a fault current of the DDA and its
Selbstverständlich soll die Erfindung nicht auf die in schematischer Weise gezeigten Ausführungsbeispiele beschränkt sein. Alle anderen konstruktiven Ausgestaltungen, welche denselben funktionalen Zweck hervorbringen, dass nämlich bei einer Kopplung der Schaltknebel eines aneinandergereihten Fehlerstrombauteils und eines Leitungsschutzschalters über ein gemeinsames Koppelelement bei einer zwangsweisen Verschwenkung des Koppelelementes zunächst der erste Schaltknebel des Fehlerstrombauteils um einen bestimmten Vorlaufwinkel verschwenkt wird, bevor dann der zweite Schaltknebel des Leitungsschutzschalters ebenfalls verschwenkt wird, sind von der vorliegenden Erfindung zumindest im Äquivalenzbereich mit umfasst.Of course, the invention should not be limited to the embodiments shown in a schematic manner. All other constructive embodiments, which produce the same functional purpose, namely that in a coupling of the control knob of a juxtaposed fault current component and a circuit breaker via a common coupling element in a forced pivoting of the coupling element, first, the first switching knob of the fault current component is pivoted about a certain lead angle before then the second switch knob of the circuit breaker is also pivoted, are encompassed by the present invention, at least in the range of equivalents.
