Abstract

An arrangement for mutually locking the actuation of at least two power switches (A, B, C) has an energy accumulator (31) associated to each power switch (A, B, C) and loaded by the rotation of the switching shaft (40). The energy accumulator (31) actuates flexible transmission means (13, 14, 15, 16) that lead to an evaluation apparatus (10, 11, 12). The energy accumulator (31) makes the mechanical locking mechanism more reliable and allows lighter transmission means to be used.

Description

Die Erfindung betrifft eine Anordnung zur gegenseitigen Verriegelung der Betätigung von wenigstens zwei Leistungsschaltern, wobei die Stellung einer Schaltwelle jedes der Leistungsschalter durch ein mechanisches Übertragungsorgan einem mechanisch wirkenden Auswertungsgerät zugeführt wird, das die Betätigung der Leistungsschalter freigibt bzw. sperrt.The invention relates to an arrangement for mutual Lock the actuation of at least two Circuit breakers, the position of a control shaft each of the circuit breakers by a mechanical Transmission device a mechanically acting evaluation device is fed, the actuation of the circuit breaker releases or blocks.

Eine Anordnung dieser Art ist durch die DE 44 09 172 A1 bekannt geworden. Die Übertragungsorgane sind dabei Drahtauslöser oder mantelgeführte Seilzüge (Bowdenzug), die in einer Schaltanlage unter Umständen eine beträchtliche Länge aufweisen können. Je nach der Anordnung der gegenseitig zu verriegelnden Leistungsschalter kann es auch erforderlich sein, die biegsamen Übertragungsorgane mit mehreren Bögen wechselnder Krümmung zu verlegen. Dabei erweist es sich, daß die Betätigung der biegsamen Übertragungsorgane einen überraschend hohen Energieaufwand erfordert, obwohl bei einer Untersuchung der Seilzüge oder Drahtauslöser eine nur geringe Reibung festgestellt werden kann.An arrangement of this type is described in DE 44 09 172 A1 known. The transmission organs are there Wire releases or sheathed cables (Bowden cable) that in a switchgear, possibly a considerable one Can have length. Depending on the arrangement of each other It may also be necessary to lock circuit breakers be the flexible transmission elements with several arches alternating curvature. It turns out that the actuation of the flexible transmission elements one Requires surprisingly high energy expenditure, although with one Examination of the cable pulls or wire releases is only a minor one Friction can be determined.

Es ist auch bekannt, zur gegenseitigen Verriegelung von Leistungsschaltern ein System von Schub- und Zugstangen zu verwenden (DE 38 41 315 A1 bzw. DE 44 09 172 A1). In diesem Fall ist gleichfalls ein beträchtlicher Energiebedarf für die Betätigung feststellbar.It is also known to interlock each other Circuit breakers a system of push and pull rods too use (DE 38 41 315 A1 or DE 44 09 172 A1). In this Case is also a considerable energy requirement for the Operation noticeable.

Der Erfindung liegt die Aufgabe zugrunde, den Energiebedarf einer Anordnung der eingangs genannten Art zu verringern und hierdurch den Aufbau gegenseitiger Verriegelungen mehrerer Leistungsschalter zu verbessern und zu erleichtern. The invention is based, the energy requirement to reduce an arrangement of the type mentioned and thereby building multiple interlocks Improve and facilitate circuit breakers.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß jeder Leistungsschalter einen durch eine im Sinne der Einschaltung erfolgende Drehung der Schaltwelle aufzuladenden Energieespeicher zur Betätigung des mechanischen Übertragungsorgans besitzt und daß daß zwischen dem Energiespeicher und der Schaltwelle eine bei der Drehung von der Einschaltstellung in die Ausschaltstellung wirksame Totgangkupplung angeordnet ist, wobei das zugeordnete Auswertungsgerät eine auf das Übertragungsorgan wirkende Rückstellfeder enthält.According to the invention, this object is achieved in that each circuit breaker one by one in the sense of Switching-on rotation of the selector shaft to be charged Energy storage for actuating the mechanical transmission element owns and that between the energy storage and the shift shaft one when rotating from the Switch-on position in the switch-off position effective lost motion clutch is arranged, the associated evaluation device a return spring acting on the transmission element contains.

In der angegebenen Anordnung hat der Energiespeicher die Eigenschaft, die Schaltwelle des Leistungsschalters von dem mechanischen Übertragungsorgan zu entkoppeln. Somit ist die Bewegung des Übertragungsorgans von der Drehung der Schaltwelle nicht starr abhängig, wie bei der bisher üblichen direkten Verbindung. Hierdurch wird die ruckartige Beanspruchung der Übertragungsorgane durch die schlagartige Drehung der Schaltwelle des Leistungsschalters vermieden, was zu einer hohen Beanspruchung an der Verbindungsstelle des Übertragungsorgans mit der Schaltwelle führt. Werden biegsame Übertragungsorgane benutzt, die eine Biegung aufweisen, so wird durch den zeitlich gestreckten Bewegungsablauf aufgrund des Energiespeichers eine starke Zunahme der Reibung zwischen dem Übertragungsorgan und seinem Mantel vermieden. Es erweist sich daher, daß sogar in einer Entfernung von mehreren Metern aufgestellte Leistungsschalter verriegelt werden können.In the specified arrangement, the energy store has the Property, the switching shaft of the circuit breaker from the to decouple mechanical transmission element. So that is Movement of the transmission organ from the rotation of the Switching shaft is not rigidly dependent, as with the previously usual direct connection. This will make the jerky Strain on the transmission organs due to the sudden Rotation of the switch shaft of the circuit breaker avoided what to high stress at the junction of the Transmission organ with the switching shaft leads. Be flexible Transmission elements used that have a bend, so is due to the temporally stretched sequence of movements the energy storage a sharp increase in friction between the transmission organ and its coat avoided. It turns out therefore, that even at a distance of several meters installed circuit breakers can be locked.

Die gleiche vorteilhafte Entkopplung der Drehung der Schaltwelle von der Betätigung eines Übertragungsorgans wird bei der Ausschaltung des Leistungsschalters durch die erwähnte Totgangkupplung erreicht. Die Rückstellfeder sorgt für einen sanften Bewegungsablauf zur Wiederherstellung der Ausgangsstellung. The same advantageous decoupling of the rotation of the Switching shaft from the actuation of a transmission element when the circuit breaker is opened by the mentioned lost motion clutch reached. The return spring ensures for a smooth movement to restore the Starting position.

Als Energiespeicher eignet sich insbesondere eine Schraubendruckfeder, deren eines Ende durch einen mit der Schaltwelle verbundenen Hebel spannbar ist und mit deren anderem Ende das mechanische Übertragungsorgan verbunden ist. Durch Auswahl einer geeigneten Feder läßt sich erreichen, daß einerseits eine erwünschte Entkopplung in dem beschriebenen Sinn zustandekommt, andererseits eine ausreichende Betätigungskraft bereitgestellt wird.One is particularly suitable as an energy store Coil compression spring, one end of which is connected to the Switching shaft connected lever can be tensioned and with their the other end, the mechanical transmission element is connected. By selecting a suitable spring, it can be achieved that on the one hand a desired decoupling in the described Sense comes about, on the other hand sufficient Actuating force is provided.

Sollen die Auswertungsgeräte von zwei Leistungsschaltern beeinflußt werden, so sind von einem der Leistungsschalter Stellungsmeldungen zu den anderen beiden Leistungsschaltern zu leiten. Hierfür eignet sich eine Ausgestaltung der Anordnung nach der Erfindung, bei der zwei gleichzeitig zu spannende Energiespeicher zur Betätigung von zwei mechanischen Übertragungsorganen besitzt.Should the evaluation devices of two circuit breakers are affected by one of the circuit breakers Position reports on the other two circuit breakers to lead. An embodiment of the is suitable for this Arrangement according to the invention, in which two at the same time exciting energy storage for the actuation of two has mechanical transmission organs.

Die Schaltwelle von Leistungsschaltern erstreckt sich bei der üblichen Bauweise der Leistungsschalter quer zur Bedienungsfront und ist an den Seitenwänden zugänglich. Es empfiehlt sich in diesem Zusammenhang, das Auswertungsgerät und einen den bzw. die Energiespeicher auf einer seitlich des Leistungsschalters angeordneten Tragplatte zu befestigen. Handelt es sich um einen einfahrbaren Leistungsschalter, so wird die Tragplatte zweckmäßig an einem den Leistungsschalter aufnehmenden Einschubrahmen befestigt. Gehört der Leistungsschalter einer berührungsgeschützten Bauart an, so empfiehlt es sich, auch beim Anbau eines Stellungsmelders nach der Erfindung Maßnahmen zur Aufrechterhaltung des Berührungsschutzes zu treffen. Hierzu kann in einer aus Isolierstoff bestehenden Seitenwand des Leistungsschalters zur Verbindung einer aus elektrisch leitendem Material bestehenden Schaltwelle und einer den bzw. die Energiespeicher spannenden Betätigungswelle eine isolierende Wellenkupplung gelagert sein, wobei die Betätigungswelle mit der Wellenkupplung lösbar in Eingriff zu bringen ist. The switching shaft of circuit breakers extends at the usual design of the circuit breaker across Operating front and is accessible on the side walls. It In this context, the evaluation device is recommended and the one or more energy storage on the side of the Circuit breaker arranged to attach the support plate. If it is a retractable circuit breaker, so the support plate is conveniently connected to the circuit breaker receiving slide-in frame attached. Belongs to the circuit breaker of a touch-protected type, so recommends it, even when mounting a position indicator after the Invention measures to maintain contact protection hold true. This can be done in an insulating material existing side wall of the circuit breaker for connection a switching shaft made of electrically conductive material and an exciting one or more energy storage Actuating shaft mounted an insulating shaft coupling be, the actuating shaft with the shaft coupling is releasably engaged.

Die Erfindung wird im folgenden anhand des in den Figuren dargestellten Ausführungsbeispieles näher erläutert.The invention is described below with reference to the figures illustrated embodiment explained in more detail.

Die Figur 1 zeigt schematisch eine Anordnung zur gegenseitigen Verriegelung von drei Leistungsschaltern.Figure 1 shows schematically an arrangement for mutual interlocking of three circuit breakers.

Einen doppelt ausgebildeten Energiespeicher eines Leistungsschalters zur Betätigung von zwei biegsamen Übertragungsorganen zeigen die Figuren 2 und 3 in zwei rechtwinklig zueinander stehenden Ansichten.A double trained energy storage one Circuit breaker for operating two flexible Transmission organs show the figures 2 and 3 in two views at right angles to each other.

In der Figur 1 sind drei Leistungsschalter A, B und C strichpunktiert angedeutet. Die Enden von Betätigungswellen 1, 2 und 3 von Stellungsmeldern 4, 5, 6 der Leistungsschalter A, B und C sind als Vierkant dargestellt. Ferner ist jedem Leistungsschalter A, B und C eine Tragplatte 7, 8 und 9 zugeordnet, auf der sich außer dem Stellungsmelder 4, 5 bzw. 6 ein als Empfänger arbeitendes Auswertungsgerät 10, 11 bzw. 12 befindet. Von dem Stellungsmelder 4 geht ein biegsames Übertragungsorgan 13 aus, das zu dem Auswertungsgerät 12 des Leistungsschalters C führt. In sinngemäß der gleichen Anordnung verbindet ein biegsames Übertragungsorgan 14 des Stellungsmelders 5 den Leistungsschalter B mit dem Auswertungsgerät 12 des Leistungsschalters C. Der Stellungsmelder 6 des Leistungsschalters C besitzt zwei Ausgänge. Von diesen ist der eine mittels eines biegsamen Übertragungsorgans 15 mit dem Auswertungsgerät 10 des Leistungsschalters A und der andere mittels eines Übertragungsorgans 16 mit dem Auswertungsgerät 11 des Leistungsschalters B verbunden. Es sind somit insgesamt vier biegsame Übertragungsorgane vorhanden.In Figure 1 there are three circuit breakers A, B and C. indicated by dash-dotted lines. The ends of actuation shafts 1, 2 and 3 of position indicators 4, 5, 6 of the circuit breakers A, B and C are shown as a square. Furthermore, everyone is Circuit breakers A, B and C have a support plate 7, 8 and 9 assigned on which, in addition to the position indicator 4, 5 or 6 an evaluation device 10, 11 or 12 is located. A flexible goes from the position indicator 4 Transmission organ 13, which to the evaluation device 12 of the Circuit breaker C leads. In the same sense Arrangement connects a flexible transmission member 14 of the Position indicator 5, the circuit breaker B with the evaluation device 12 of the circuit breaker C. The position indicator 6 of circuit breaker C has two outputs. From this is the one by means of a flexible transmission element 15 with the evaluation device 10 of the circuit breaker A and the other by means of a transmission element 16 with the Evaluation device 11 of the circuit breaker B connected. It are a total of four flexible transmission elements available.

Zur Funktion der Auswertungsgeräte 10, 11 und 12 ist zu bemerken, daß diese jeweils einen Ausgangsschieber 17, 18 bzw. 19 aufweisen, der mit einer schematisch dargestellten Einschaltverklinkung zusammenwirkt. Diese weist eine Einschalt-Halbwelle 20 und eine daran abstützbare Einschaltklinke 21 auf. Durch eine Einschalttaste 22 ist die Einschalt-Halbwelle 20 nur dann zur Freigabe der Einschaltklinke 21 drehbar, wenn ein mit dem Ausgangsschieber 10, 11 bzw. 12 verbundener Sperrschieber 23 zwischen der Einschalttaste 22 und einem auf der Einschaltwelle 20 sitzenden Fortsatz 24 eingreift. Ist nämlich der Sperrschieber 23 zurückgezogen, wie dies bei dem Leistungsschalter C in der Figur 1 der Fall ist, so kann die Einschalttaste 22 den Fortsatz 24 nicht erreichen. Es ist daher nicht möglich, den Leistungsschalter C einzuschalten.The function of the evaluation devices 10, 11 and 12 is too note that these each have an output slide 17, 18th or 19, which is shown with a schematically Interlocking interacts. This one Switch-on half-wave 20 and a switch which can be supported thereon 21 on. By a power button 22 is the Switch-on half-wave 20 only then to release the switch 21 rotatable when a with the output slide 10, 11th or 12 connected locking slide 23 between the power button 22 and one sitting on the switch-on shaft 20 Extension 24 engages. Is namely the gate valve 23rd withdrawn, as is the case with the circuit breaker C in the Figure 1 is the case, the power button 22 can Do not reach extension 24. It is therefore not possible to Switch on circuit breaker C.

Der Zweck der in der Figur 1 dargestellten Anordnung ist näher aus dem gleichfalls in der Figur links oben gezeigten schematischen Schaltplan ersichtlich. Dieser stellt eine Schaltanlage mit den drei Leistungsschaltern A, B und C sowie einem Transformator und einem Generator dar. Dabei ist der Leistungsschalter A dem Transformator und der Leistungsschalter C dem Generator zugeordnet. Der verbleibende Leistungsschalter B dient als Kuppelschalter im Zuge einer Sammelschiene, die wahlweise über den Leistungsschalter A aus dem Transformator oder über den Leistungsschalter C aus dem Generator gespeist werden kann. Daraus ergibt sich als Bedingung, daß der Leistungsschalter C gegen Einschalten gesperrt sein muß, wenn die Leistungsschalter A und B geschlossen sind. Umgekehrt darf sich der Leistungsschalter C nicht einschalten lassen, wenn die Leistungsschalter A und/oder B eingeschaltet sind.The purpose of the arrangement shown in Figure 1 is closer from that also shown in the figure at the top left schematic circuit diagram can be seen. This represents one Switchgear with the three circuit breakers A, B and C as well a transformer and a generator Circuit breaker A the transformer and the circuit breaker C assigned to the generator. The remaining one Circuit breaker B serves as a tie switch in the course of a Busbar, which can be selected via circuit breaker A. the transformer or via the circuit breaker C from the Generator can be fed. From this it results as Condition that the circuit breaker C against switching on must be locked when the circuit breakers A and B are closed. Conversely, the circuit breaker C do not let switch on if the circuit breaker A and / or B are switched on.

Durch Kupplungsglieder 27 ist dafür gesorgt, daß die Stellungsmelder 4, 5 und 6 zwangsläufig auf die zugeordneten Ausgangsschieber 17, 18 und 19 der Auswertungsgeräte 10, 11 und 12 wirken. Dargestellt ist in der Figur 1 der Zustand, daß die Leistungsschalter A und B eingeschaltet und schaltbar sind und der Leistungsschalter C gegen Einschalten gesperrt ist. Dies geschieht dadurch, daß der Stellungsmelder 4 mittels des Übertragungsorgans 13 einen Eingangsschieber 25 des Auswertungsgerätes 12 betätigt und dadurch den Sperrschieber 23 von dem Fortsatz 24 abzieht. Das gleiche Ergebnis hat eine Betätigung des Leistungsschalters B mittels des Stellungsmelders 2 und des Übertragungsorgans 14, das auf einen zweiten Eingangsschieber 26 des Auswertungsgerätes 12 wirkt.Coupling members 27 ensure that the Position indicators 4, 5 and 6 inevitably on the assigned Output slide 17, 18 and 19 of the evaluation devices 10, 11th and 12 act. The state is shown in FIG. 1, that the circuit breakers A and B turned on and switchable and the circuit breaker C are locked against switching on is. This happens because the position indicator 4th an input slide 25 by means of the transmission element 13 of the evaluation device 12 actuated and thereby the locking slide 23 withdraws from the extension 24. The same result has an operation of the circuit breaker B by means of Position indicator 2 and the transmission element 14 that on a second input slide 26 of the evaluation device 12 works.

Obwohl die Darstellung gemäß der Figur 1 schematisch ist, veranschaulicht sie dennoch eine der Praxis durchaus entsprechende Verlegung der biegsamen Übertragungsorgane mit mehreren Biegungen, die einen unterschiedlichen und relativ engen Krümmungsradius aufeisen können. Dennoch wird durch die besondere Gestaltung der Stellungsmelder 10, 11 und 12, auf die im folgenden anhand der Figuren 2 und 3 eingegangen wird, eine überraschende Leichtgängigkeit der Anordnung mit entsprechend sicherer Funktion erzielt.Although the representation according to FIG. 1 is schematic, it nevertheless illustrates one of the realities appropriate laying of the flexible transmission elements with several bends that are different and relative can iron out narrow radius of curvature. Nevertheless, the special design of the position indicators 10, 11 and 12 which is discussed below with reference to FIGS. 2 and 3, a surprising ease of movement with the arrangement achieved correspondingly safe function.

Die Figuren 2 und 3 zeigen den Stellungsmelder 6, der mit den Stellungsmeldern 4 und 5 sinngemäß übereinstimmt. Auf der Betätigungswelle 3 sitzt ein symmetrischer zweiarmiger Hebel 28, der an seinen Enden gelenkig mit je einem Schieber 30 verbunden ist. Jeder der Schieber 30 dient als Widerlager eines als Schraubendruckfeder ausgebildeten Energiespeichers 31, an dessen anderem Ende die biegsamen Übertragungsorgane 15 bzw. 16 angreifen. Zugeordnete Mäntel 32 bzw. 33 der biegsamen Übertragungsglieder 15 und 16 sind an Schenkeln 34 bzw. 35 eines Tragbügels 36 abgestützt, an dem die gegenläufig bewegten Schieber 30 geführt sind.Figures 2 and 3 show the position indicator 6, with the Position indicators 4 and 5 correspond mutatis mutandis. On the Actuating shaft 3 is a symmetrical two-armed lever 28, which is articulated at its ends with a slide 30 each connected is. Each of the slides 30 serves as an abutment an energy store designed as a helical compression spring 31, at the other end of which the flexible transmission elements Attack 15 or 16. Associated coats 32 and 33 respectively flexible transmission members 15 and 16 are on legs 34 or 35 of a support bracket 36 supported on which the opposite moving slide 30 are guided.

Wird nur ein Übertragungsorgan zur Meldung der Schaltstellung eines Leistungsschalters benötigt, wie in dem Fall der Leistungsschalter A und B, so wird der Stellungsmelder mit nur einem Schieber 30 ausgestattet, wie dies bei den Stellungsmeldern 4 und 5 der Fall ist. Will only be a transmission element for reporting the switch position a circuit breaker, as in the case of Circuit breakers A and B, so the position indicator with equipped only one slider 30, as in the Position indicators 4 and 5 are the case.

Wesentlich für die gewünschte Funktion ist die Entkopplung der äußerst raschen Drehung der Betätigungswelle 3 von den biegsamen Übertragungsorganen 15 und 16 dadurch, daß zunächst die Energiespeicher 31 gespannt werden. Bei geeigneter Wahl der Federstärke, die anhand einfacher Versuche zu treffen ist, wird einerseits eine sichere Betätigung der Auswertungsgeräte 10, 11 und 12 und andererseits eine verlustarme Übertragung der Bewegung der Betätigungswelle 3 zu den Auswertungsgeräten 10 bzw. 11 erreicht. Die gegenüber einer direkten Betätigung der biegsamen Übertragungsorgane erheblich verminderte Beanspruchung gestattet es, leichtere und daher besser verlegbare biegsame Übertragungsorgane zu verwenden. Zur Rückführung der Anordnung in die Ausgangslage sind den Eingangsschiebern der Auswertungsgeräte 10, 11, und 12 Rückstellfedern 29 zugeordnet (Figur 1). Diese sorgen für eine gleichfalls von den Betätigungswellen 1, 2 oder 3 bzw. der zugeordneten Schaltwelle des betreffenden Leistungsschalters A, B oder C unabhängige sanfte Betätigung der Übertragungsorgane 13, 14, 15 oder 16. Dies geschieht dadurch, daß die betreffende Betätigungswelle 1, 2 oder 3 aufgrund eines Langloches 42 in jedem der Schieber 30 (Figur 3) einen Leerhub ausführen kann. Der Schieber 30 wird dann durch die am anderen Ende des zugeordneten Übertragungsorgans wirkende Rückstellfeder 29 in die Ausgangslage gemäß der Figur 3 zurückgezogen.Decoupling is essential for the desired function the extremely rapid rotation of the actuating shaft 3 of the flexible transmission elements 15 and 16 in that initially the energy storage 31 can be tensioned. With a suitable choice the spring strength, which can be made using simple experiments is, on the one hand, safe operation of the evaluation devices 10, 11 and 12 and on the other one low-loss transmission of the movement of the actuating shaft 3 to the evaluation devices 10 and 11 reached. The opposite direct actuation of the flexible transmission elements significantly reduced stress allows lighter and therefore more relocatable flexible transmission elements use. To return the arrangement to the starting position are the input slides of the evaluation devices 10, 11, and 12 return springs 29 assigned (Figure 1). These ensure one of the actuating shafts 1, 2 or 3 or the assigned switching shaft of the relevant circuit breaker A, B or C independent gentle actuation of the Transmission organs 13, 14, 15 or 16. This happens in that the actuating shaft 1, 2 or 3 due to an elongated hole 42 in each of the slider 30 (Figure 3) can carry out an idle stroke. The slider 30 will then through those at the other end of the associated transmission organ acting return spring 29 in the starting position according to the Figure 3 withdrawn.

Der Figur 2 ist noch zu entnehmen, daß der Stellungsmelder 6 auf der Tragplatte 9 befestigt ist, die ihrerseits je nach der Einbauart des zugehörigen Leistungsschalters C angeordnet ist. Insbesondere ist die Tragplatte 9 an dem Leistungsschalter C befestigt, wenn dieser fest eingebaut ist. Befindet sich der Leistungsschalter C dagegen in einem Einschubrahmen, so ist die Tragplatte 9 an dem Einschubrahmen befestigt. Durch eine lösbare Wellenkupplung 37, die auf das Ende einer Schaltwelle 40 des Leistungsschalters C aufgesetzt ist, wird eine drehschlüssige Kupplung zwischen der Schaltwelle 40 und der Betätigungswelle 4 hergestellt. Die Wellenkupplung 37 ist seitlich offen ausgebildet, um einen selbsttätigen Eingriff beim Einfahren des Leistungsschalters 1 in seinen Einschubrahmen zu ermöglichen. Mit Rücksicht auf die Berührungssicherheit des Leistungsschalters C (und entsprechend der gleichfalls mit Stellungsmeldern versehenen Leistungsschalter A und B) endet die Schaltwelle 40 innerhalb des aus Isolierstoff bestehenden Gehäuses, dessen dem Stellungsmelder 6 zugewandte Seitenwand 41 in der Figur 3 teilweise sichtbar ist. Die Wellenkupplung 37 besteht gleichfalls aus Isolierstoff und verhindert eine Berührung der aus elektrisch leitenden Material bestehenden Schaltwelle 40 durch einen Benutzer.It can also be seen from FIG. 2 that the position indicator 6 is attached to the support plate 9, which in turn depending on the type of installation of the associated circuit breaker C. is. In particular, the support plate 9 is on the circuit breaker C attached when it is permanently installed. In contrast, the circuit breaker C is in one Slide-in frame, so is the support plate 9 on the slide-in frame attached. By a releasable shaft coupling 37, which on the End of a switching shaft 40 of the circuit breaker C placed is a rotary coupling between the Switch shaft 40 and the actuating shaft 4 made. The Shaft coupling 37 is laterally open to one automatic intervention when opening the circuit breaker 1 in its slide-in frame. With regard to the safety of touch of the circuit breaker C (and accordingly the one also equipped with position indicators Circuit breakers A and B) the switching shaft 40 ends within of the housing made of insulating material, the Position indicator 6 facing side wall 41 in FIG. 3 is partially visible. The shaft coupling 37 is made also made of insulating material and prevents contact the switching shaft made of electrically conductive material 40 by one user.

Wie bereits erwähnt, kann die erforderliche Stärke der als Energiespeicher 31 benutzten Druckfeder durch einen Versuch leicht festgestellt werden. Dies gilt auch für die Rückstellfeder 29. Dabei ist zu beachten, daß die Rückstellfeder 29 erheblich schwächer als der Energiespeicher 31 sein sollte, da sie nur die Aufgabe hat, den zugeordneten Eingangsschieber, den als biegsames Übertragungsorgan benutzten Seilzug oder ein Gestänge und den Schieber 30 des betreffenden Stellungsmelders in die Ausgangslage zurückzubewegen. Auch in diesem Fall ist der Bewegungsablauf sanft und reibungsarm, weil die Rückstellung von der widerum ruckartigen Drehung der Schaltwelle 40 entkoppelt ist.As mentioned earlier, the required strength of the as Energy storage 31 used compression spring by experiment can be easily identified. This also applies to the return spring 29. It should be noted that the return spring 29 should be considerably weaker than the energy store 31, since it only has the task of the assigned input slide, used as a flexible transmission element Cable or a linkage and the slider 30 of the relevant Position transmitter to move back to the starting position. In this case too, the movement is smooth and low friction, because the provision of the turn abrupt rotation of the control shaft 40 is decoupled.
