Description

Die Erfindung bezieht sich auf eine Schaltgeräteauslöseeinrichtung für ein Schaltgerät mit relativ zueinander bewegbaren Kontaktstücken, aufweisend eine Getriebeanordnung zum Erzeugen einer Relativbewegung zwischen den Kontaktstücken mit einer Sperrklinke und mit einem zu einer Betätigung der Sperrklinke gegen die Sperrklinke bewegbaren Auslösemittel.The invention relates to a switching device tripping device for a switching device with relatively movable contact pieces, comprising a gear arrangement for generating a relative movement between the contact pieces with a pawl and with a to actuate the pawl against the pawl movable release means.

Eine derartige Schaltgeräteauslöseeinrichtung ist beispielsweise aus dem Gebrauchsmuster DE 297 15 900 U1 bekannt. Die dortige Schaltgeräteauslöseeinrichtung sieht vor, eine Getriebeanordnung zum Betreiben eines Schaltgerätes mit relativ zueinander bewegbaren Kontaktstücken zu verwenden, wobei die Getriebeanordnung eine Sperrklinke aufweist und zum Betätigen der Sperrklinke ein bewegbares Auslösemittel eingesetzt ist. Die bekannte Schaltgeräteauslöseeinrichtung weist für ein Schaltgerät mit mehreren Schaltpolen für jeden Schaltpol jeweils eine Sperrklinke und ein zugeordnetes Auslösemittel auf. Somit ist es möglich, die Auslösemittel untereinander zu synchronisieren und die mehrere Schaltpole annähernd zeitgleich auszulösen oder einen erwünschten zeitlichen Versatz eines Auslösens von Schaltbewegungen an den einzelnen Schaltpolen des Schaltgerätes einzustellen. Nachteilig ist allerdings, dass bei einer Störung einer Schaltgeräteauslöseeinrichtung an einem der Schaltpole das gesamte Schaltgerät ausfällt. Derartige Ausfälle sollen vermieden werden. Ferner offenbart DE 38 23 101 A1 (Figuren 4 und 5) eine Schaltgeräteauslöseeinrichtung gemäß dem Oberbegriff des Anspruchs 1.Such a switching device tripping device is for example from the utility model DE 297 15 900 U1 known. The local switching device trip device provides to use a gear assembly for operating a switching device with relatively movable contact pieces, wherein the gear assembly has a pawl and a movable release means is used to operate the pawl. The known switching device triggering device has for a switching device with a plurality of switching poles for each switching pole in each case a pawl and an associated release means. Thus, it is possible to synchronize the release means with each other and to trigger the plurality of switching poles approximately at the same time or to set a desired time offset of a triggering of switching movements at the individual switching poles of the switching device. The disadvantage, however, is that in case of failure of a switching device trip device on one of the switching poles, the entire switching device fails. Such failures should be avoided. Further disclosed DE 38 23 101 A1 ( FIGS. 4 and 5 ) a switching device tripping device according to the preamble of claim 1.

Daher ist es Aufgabe der Erfindung eine Schaltgeräteauslöseeinrichtung anzugeben, welche eine erhöhte Betriebssicherheit aufweist.It is therefore an object of the invention to provide a switching device trip device, which has an increased reliability.

Erfindungsgemäß würde die Aufgabe bei einer Schaltgeräteauslöseeinrichtung der eingangs genannten Art durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object would be achieved in a switching device tripping device of the type mentioned by the features of claim 1.

Ein elektrisches Schaltgerät ist beispielsweise ein Leistungsschalter, welcher einem Unterbrechen bzw. einem Herstellen eines Strompfades zwischen zwei Strombahnabschnitten dient. Als solches weist ein Schaltgerät beispielsweise relativ zueinander bewegbare Kontaktstücke auf. Zum Unterbrechen bzw. zum Herstellen eines Strompfades ist eine Relativbewegung zwischen den Kontaktstücken zu erzeugen. So ist es beispielsweise möglich, dass zum Herstellen eines Strompfades die beiden Kontaktstücke einander nähern und schließlich eine galvanische Kontaktierung derselben erfolgt, so dass ein geschlossener Strompfad entsteht. Im umgekehrten Falle ist bei einem Öffnen eines Strompfades eine Entfernung der beiden relativ zueinander bewegbaren Kontaktstücke voneinander vorgesehen, so dass schließlich eine galvanische Trennung derselben erfolgt. Entsprechend ist eine Trennstelle im Strompfad gebildet und der Strompfad ist unterbrochen.An electrical switching device is, for example, a circuit breaker which serves to interrupt or establish a current path between two current path sections. As such, a switching device has, for example, relatively movable contact pieces. For interrupting or for producing a current path, a relative movement between the contact pieces is to be generated. Thus, it is possible, for example, for the manufacture of a current path, the two contact pieces approach each other and finally a galvanic contacting thereof takes place, so that a closed current path is formed. In the opposite case, a removal of the two relatively movable contact pieces from each other is provided when opening a current path, so that finally a galvanic separation thereof takes place. Accordingly, a separation point is formed in the current path and the current path is interrupted.

Das elektrische Schaltgerät kann einpolig oder mehrpolig ausgeführt werden. Ein einpoliges Schaltgerät ist dazu eingerichtet, einen einzigen Strompfad zu schalten. Ein mehrpoliges Schaltgerät weist mehrere Schaltpole auf. Ein mehrpoliges Schaltgerät kann dazu eingesetzt werden, mehrere Strompfade eines mehrphasigen Elektroenergieübertragungsnetzes zu schalten. Entsprechend erfolgen Schaltbewegungen der einzelnen Schaltpole eines mehrpoligen Schaltgerätes zeitlich aufeinander abgestimmt.The electrical switching device can be carried out unipolar or multipolar. A single-pole switching device is set up to switch a single current path. A multi-pole switching device has several switching poles. A multi-pole switching device can be used to switch several current paths of a multi-phase electric power transmission network. Accordingly, switching movements of the individual switching poles of a multi-pole switching device are timed to each other.

Je nach Ausgestaltung des elektrischen Schaltgerätes ist ein Ein- bzw. Ausschalten des Schaltgerätes mit vergleichsweise schnellen Relativbewegungen der Kontaktstücke zueinander verbunden. Diese muss gegebenenfalls innerhalb von wenigen Millisekunden abrufbar sein, um einen Schaltvorgang rasch durchzuführen. Üblicherweise werden daher Speichervorrichtungen eingesetzt, welche während eines relativ langen Zeitraumes aufgeladen werden können. Die in der Speichervorrichtung zwischengespeicherte Energie kann innerhalb eines kürzeren Zeitraumes abgegeben werden, als ein Aufladen der Speichervorrichtung in Anspruch nimmt. Bewährt haben sich beispielsweise mechanische Speicher, wie beispielsweise Federspeicher, welche zumindest eine Speicherfeder aufweisen, die zum Aufladen gespannt wird und zur Erzeugung einer Relativbewegung der Schaltkontaktstücke zueinander schlagartig entspannt werden können.Depending on the configuration of the electrical switching device, switching on or off of the switching device is connected to one another with comparatively rapid relative movements of the contact pieces. This may need to be retrievable within a few milliseconds to quickly perform a switching operation. Usually, therefore, storage devices are used which can be charged for a relatively long period of time. The energy stored in the memory device can be delivered within a shorter period of time than charging the memory device takes up. Proven, for example, mechanical memory, such as spring memory, which have at least one memory spring, which is tensioned for charging and can be relaxed suddenly to produce a relative movement of the switching contact pieces.

Speicherfedern können in verschiedenen Bauformen Verwendung finden. Beispielsweise können Schraubenfedern, Spiralfedern, Stabfedern, Gasfedern etc. verwendet werden. Beispielsweise kann durch eine Getriebeanordnung ein Spannen der Speicherfeder bzw. ein Entspannen der Speicherfeder durchgeführt werden. Die Speicherfeder ist Teil der Getriebeanordnung, wobei die der Speicherfeder während eines Entspannens entnommene Energie in eine Bewegung eines bewegbaren Kontaktstückes oder mehrerer bewegbarer Kontaktstücke gewandelt wird. Um ein leichtes Freigeben einer gespannten Speicherfeder zu ermöglichen, ist die Getriebeanordnung weiterhin mit einer Sperrklinke ausgestattet, welche die Speicherfeder im gespannten Zustand hält bzw. blockiert. Eine Sperrklinke kann beispielsweise einen Mechanismus umfassen, welcher einem Blockieren einer gespannten Feder ermöglicht, wobei zum Freigeben der gespannten Feder eine kleine Energiemenge nötig ist. Beispielsweise kann die Sperrklinke eine mehrteilige Mechanik wie z. B. eine Kniehebelkonstruktion aufweisen, welche durch ein Auslösemittel zum Einbruch gebracht wird. Die Sperrklinke ist durch ein Auslösemittels bewegbar, wobei durch eine Bewegung der Sperrklinke die gespannte Speicherfeder freigegeben wird. Entsprechend kann mittels der Getriebeanordnung zum Erzeugen einer Relativbewegung zwischen den Kontaktstücken des Schaltgerätes eine Freigabe einer zwischengespeicherten Kraft vorgenommen werden, welche einem Antrieb zumindest eines der Kontaktstücke dient. Vorzugsweise sollte eine Bewegung eines Auslösemittels eine Ausschaltbewegung, d. h. eine Trennung der relativ zueinander bewegbaren Kontaktstücke bewirken.Memory springs can be used in various designs. For example, coil springs, coil springs, bar springs, gas springs, etc. can be used. For example, a tensioning of the storage spring or a release of the storage spring can be carried out by a gear arrangement. The storage spring is part of the gear arrangement, wherein the energy taken from the storage spring during relaxation is converted into a movement of a movable contact piece or a plurality of movable contact pieces. In order to allow easy release of a tensioned storage spring, the gear assembly is further equipped with a pawl, which holds the storage spring in the tensioned state or blocks. For example, a pawl may include a mechanism that allows a tensioned spring to lock, with a small amount of energy being required to release the tensioned spring. For example, the pawl a multi-part mechanism such. B. have a toggle construction, which is brought by a trigger means for burglary. The pawl is movable by a trigger means, wherein the tensioned memory spring is released by a movement of the pawl. Accordingly, by means of the gear arrangement for generating a relative movement between the contact pieces of the switching device, a release of a cached force can be made, which serves a drive at least one of the contact pieces. Preferably, movement of a triggering means should include a switch-off movement, i. H. cause a separation of the relatively movable contact pieces.

Nutzt man nunmehr ein erstes sowie ein zweites Auslösemittel, welche gegen dieselbe Sperrklinke bewegbar sind bzw. dieselbe Sperrklinke antreiben, so ist es möglich, die Zuverlässigkeit der Schaltgeräteauslöseeinrichtung zu erhöhen. Selbst bei einer Störung an einem der Auslösemittel ist es möglich, dass das verbleibende Auslösemittel allein eine Bewegung der Sperrklinke bewirkt. Die beiden Auslösemittel sind dabei derart ausgelegt, dass jedes der Auslösemittel allein eine ausreichende Energie aufbringen kann, um die Sperrklinke zu bewegen und in der Folge eine in einer Speichervorrichtung zwischengespeicherte Energie freizugeben. Die beiden Auslösemittel sollten mechanisch parallel geschaltet sein.If one uses now a first and a second release means, which are movable against the same pawl or the same Drive pawl, so it is possible to increase the reliability of the switching device tripping device. Even in the event of a fault on one of the triggering means, it is possible for the remaining triggering means to cause only movement of the pawl. The two triggering means are designed such that each of the triggering means alone can apply sufficient energy to move the pawl and subsequently release an energy stored in a memory device. The two release devices should be mechanically connected in parallel.

Eine weitere vorteilhafte Ausgestaltung kann vorsehen, dass die Auslösemittel jeweils linear verschieblich gelagert sind.A further advantageous embodiment can provide that the release means are each mounted linearly displaceable.

Eine verschiebliche Lagerung der Auslösemittel ermöglicht es, platzsparende Konstruktionen zu wählen, um die Auslösemittel innerhalb der Getriebeanordnung zu positionieren. Durch eine linear verschiebliche Lagerung kann in einfacher Weise ein in Richtung der Verschiebeachse der Auslösemittel vollzogener Hub auf die Sperrklinke abgegeben werden. Damit ist es möglich, die Sperrklinke direkt und unmittelbar durch die beiden Auslösemittel anzusteuern und so auf zwischengeschaltete Baugruppen einer kinematischen Kette zu verzichten. Dadurch wird eine erhöhte Zuverlässigkeit des Betriebes erreicht. Neben einem direkten Antreiben der Sperrklinke über die Auslösemittel kann auch ein indirekter bzw. mittelbarer Antrieb der Sperrklinke über die Auslösemittel vorgesehen sein. So kann beispielsweise eine Bewegung eines Auslösemittels über eine kinematische Kette geleitet werden. Damit ist eine unmittelbare räumliche Nähe von Auslösemittel und Sperrklinke nicht unbedingt notwendig. Als Teile einer kinematischen Kette können beispielsweise Hebel, Stößel, Bolzen, Zahnräder, Zahnstangen, Kettenzüge, Seilzüge usw. eingesetzt werden.Slidable mounting of the release means allows space-saving designs to be selected to position the release means within the gear assembly. By a linearly displaceable mounting a completed in the direction of the displacement axis of the trigger means stroke can be delivered to the pawl in a simple manner. This makes it possible to control the pawl directly and directly by the two trigger means and so to dispense with intermediate modules of a kinematic chain. As a result, an increased reliability of the operation is achieved. In addition to a direct driving of the pawl on the trigger means and an indirect or indirect drive of the pawl can be provided on the release means. For example, a movement of a triggering means can be conducted via a kinematic chain. Thus, an immediate spatial proximity of release means and pawl is not essential. As parts of a kinematic chain, for example, levers, plungers, bolts, gears, racks, chain hoists, cables, etc. can be used.

Eine weitere vorteilhafte Ausgestaltung kann vorsehen, dass das erste Auslösemittel über eine erste Antriebseinrichtung und das zweite Auslösemittel über eine zweite Antriebseinrichtung angetrieben sind.A further advantageous embodiment can provide that the first triggering means are driven via a first drive means and the second trigger means via a second drive means.

Der Einsatz einer ersten Antriebseinrichtung und einer zweiten Antriebseinrichtung für jeweils eines der Auslösemittel weist den Vorteil auf, dass unabhängig vom Zustand des einen Auslösemittels das andere Auslösemittel betriebsfähig bleiben kann. Dazu sollten die Antriebseinrichtungen unabhängig voneinander ihre Kraftwirkungen entfalten. Als Antriebseinrichtung eignen sich beispielsweise elektrodynamische Antriebe, pneumatische Antriebe, hydraulische Antriebe usw., welche in der Lage sind, in Abhängigkeit eines Ansteuersignals eine Bewegung des Auslösemittels zu initiieren. Als vorteilhaft haben sich dabei elektrodynamische Antriebe erwiesen, da diese bei kompakten Bauformen hohe Stellkräfte auf das Auslösemittel ausüben können. Weiterhin ist eine Ansteuerung eines elektrodynamischen Antriebes vergleichsweise einfach möglich. Die Antriebseinrichtungen können dabei von ein und derselben Steuereinrichtung angesteuert werden. Es kann jedoch auch vorgesehen sein, dass unabhängig voneinander arbeitende Steuereinrichtungen jeweils die erste Antriebseinrichtung bzw. die zweite Antriebseinrichtung ansteuern. Vorteilhafterweise sollte vorgesehen sein, dass die Ansteuerung der beiden Antriebseinrichtungen möglichst zeitgleich erfolgt. Dies kann insbesondere dadurch erreicht werden, dass eine gemeinsame Steuereinrichtung für beide Antriebseinrichtungen vorgesehen ist, so dass dieselben Impulse zum Ansteuern von erster und zweiter Antriebseinrichtung genutzt werden können. Es kann jedoch auch vorgesehen sein, dass zwei nach unterschiedlichen Kriterien arbeitende Steuereinrichtungen zum Einsatz gelangen, die beispielsweise nach unterschiedlichen Algorithmen arbeiten und so zusätzlich eine Fehlfunktion einer Schaltgeräteauslöseeinrichtung reduzieren.The use of a first drive device and a second drive device for each one of the release means has the advantage that regardless of the state of the one triggering means, the other release means can remain operable. For this purpose, the drive devices should independently develop their force effects. For example, electrodynamic drives, pneumatic drives, hydraulic drives, etc., which are capable of initiating a movement of the triggering means in response to a drive signal, are suitable as a drive device. Electrodynamic drives have proven to be advantageous, since they can exert high actuating forces on the triggering means in compact designs. Furthermore, a control of an electrodynamic drive is comparatively easy. The drive devices can be controlled by one and the same control device. However, it can also be provided that independently operating control devices in each case control the first drive device or the second drive device. Advantageously, it should be provided that the control of the two drive means takes place as possible at the same time. This can be achieved, in particular, by providing a common control device for both drive devices, so that the same pulses can be used to drive the first and second drive devices. However, it can also be provided that two control devices operating according to different criteria are used which, for example, operate according to different algorithms and thus additionally reduce a malfunction of a switching device triggering device.

Weiterhin kann vorteilhaft vorgesehen sein, dass die erste und die zweite Antriebseinrichtung unabhängig voneinander eine Kraftwirkung auf das jeweils zugeordnete Auslösemittel ausüben.Furthermore, it can be advantageously provided that the first and the second drive means independently exert a force on the respective associated release means.

Wirken die beiden Antriebseinrichtungen jeweils unabhängig voneinander auf das jeweilige Auslösemittel ein, so ist es möglich, dass jedes der Auslösemittel unabhängig von dem anderen Auslösemittel eine Kraftwirkung auf die Sperrklinke bewirkt. Damit kann die Sperrklinke von jedem der Auslösemittel, unabhängig vom Betriebszustand des jeweils anderen Auslösemittels bzw. dessen zugeordneter Antriebseinrichtung, eine Bewegung der Sperrklinke bewirken.If the two drive devices each act independently on the respective triggering means, then it is possible for each of the triggering means to exert a force on the pawl independently of the other triggering means. Thus, the pawl of each of the trigger means, regardless of the operating state of the other triggering means or its associated drive means, cause a movement of the pawl.

Eine weitere vorteilhafte Ausgestaltung kann vorsehen, dass das zweite Auslösemittel unter Zwischenlage des ersten Auslösemittels gegen die Verriegelungsklinke bewegbar ist.A further advantageous embodiment can provide that the second release means with the interposition of the first triggering means against the locking pawl is movable.

Ist die Schaltgeräteantriebseinrichtung derart eingerichtet, dass das zweite Auslösemittel unter Zwischenlage des ersten Auslösemittels gegen die Verriegelungsklinke bewegbar ist, so kann beispielsweise eine raumsparende Lösung für die Schaltgeräteauslöseeinrichtung gefunden werden. Die beiden Auslösemittel sind mechanisch in Reihe verschaltet. Dadurch, dass das zweite Auslösemittel unter Zwischenlage des ersten Auslösemittels gegen die Verriegelungsklinke bewegbar ist, ist das erste Auslösemittel Teil einer kinematischen Kette, die einer Kraft und Bewegungsübertragung von dem zweiten Auslösemittel bis zu der Sperrklinke dient. Zusätzlich kann auch im Verlauf der kinematischen Kette in die kinematische Kette über die erste Antriebseinrichtung eine Antriebskraft eingekoppelt werden. Somit können die Kraftwirkungen er beiden Auslösemittel einander überlagern, um die Stellkraft an der Sperrklinke zu erhöhen. Es kann jedoch auch vorgesehen sein, dass das zweite Auslösemittel hilft, ein Losreißmoment des ersten Auslösemittels zu überwinden. Insbesondere bei relativ selten schaltenden Schaltgeräten kann es vorkommen, dass die Getriebeeinrichtung bzw. die Auslösemittel in ihren Lagern blockiert sind. Beispielsweise können Fette und Öle verharzen, Metallteile können korrodieren und Lager so schwergängig werden. Durch eine mechanische Reihenschaltung der beiden Auslösemittel kann ein Festsetzen des ersten Auslösemittels durch die zusätzliche Kraftwirkung des zweiten Auslösemittels überwunden und die Schaltgeräteauslöseeinrichtung wieder betriebsbereit gemacht werden.If the switching device drive device is set up such that the second triggering means can be moved against the locking pawl with the first triggering means being interposed, then, for example, a space-saving solution for the switching device tripping device can be found. The two release devices are connected mechanically in series. Characterized in that the second triggering means is movable with the interposition of the first triggering means against the locking pawl, the first triggering means is part of a kinematic chain which serves a force and motion transmission from the second triggering means to the pawl. In addition, a driving force can also be coupled in the course of the kinematic chain in the kinematic chain via the first drive means. Thus, the force effects of both trigger means can overlap each other to increase the force on the pawl. However, it can also be provided that the second triggering means helps to overcome a breakaway torque of the first triggering means. Particularly in the case of relatively seldom switching switching devices, it may happen that the transmission device or the release means are blocked in their bearings. For example, greases and oils can harden, metal parts can corrode and bearings become so stiff. By a mechanical series connection of the two triggering means, a setting of the first triggering means can be overcome by the additional force effect of the second triggering means and the switching device tripping device to be made operational again.

Erfindungsgemäß sind Bewegungsachsen von erstem und zweitem Auslösemittel parallel, insbesondere koaxial zueinander ausgerichtet.According to the invention, axes of movement of the first and second triggering means are aligned parallel, in particular coaxially with one another.

Insbesondere bei einer linear verschieblichen Lagerung der Auslösemittel sollten die Auslösemittel möglichst parallel, insbesondere koaxial zueinander ausgerichtet sein. Eine Parallelität ermöglicht es, Kraftwirkungen in Richtung der Bewegungsachsen der beiden Auslösemittel gleichartig auf die Verriegelungsklinke einwirken zu lassen, so dass mechanisch einfache Verriegelungsklinken konstruiert werden können, die einerseits große Haltekräfte für eine gespannte Speicherfeder aufbringen können und andererseits durch kleinere Stellkräfte die Speicherfeder freigeben können. Insbesondere bei einer koaxialen Ausrichtung der Bewegungsachsen der Auslösemittel ist beispielsweise auch eine Betätigung der Verriegelungsklinke über das zweite Auslösemittel unter Zwischenlage des ersten Auslösemittels in einfacher Art und Weise möglich. Beispielsweise können die Auslösemittel im Wesentlichen bolzenförmig ausgeführt sein, wobei die Bolzen axial hintereinander liegend ausgerichtet sind und der eine Bolzen gegen den anderen Bolzen in Achsrichtung treibbar ist.In particular, in the case of a linearly displaceable mounting of the triggering means, the triggering means should be aligned as parallel as possible, in particular coaxially with one another. A parallelism makes it possible to act force acting in the direction of the axes of movement of the two trigger means similar to the locking pawl, so that mechanically simple locking pawls can be constructed, on the one hand can muster large holding forces for a tensioned storage spring and on the other hand can release the storage spring by smaller actuating forces. In particular, in a coaxial alignment of the axes of movement of the trigger means, for example, an actuation of the locking pawl on the second trigger means with the interposition of the first trigger means in a simple manner possible. For example, the release means may be designed substantially bolt-shaped, wherein the bolts are axially aligned one behind the other and a bolt against the other bolt in the axial direction can be driven.

Erfindungsgemäß ist das zweite Auslösemittel an dem ersten Auslösemittel geführt. Insbesondere bei zunehmend erforderlicher Miniaturisierung von Antriebseinrichtungen und damit auch von Schaltgeräteauslöseeinrichtungen mit einer Getriebeanordnung ist es nötig, die einzelnen Baugruppen immer näher zueinander zu positionieren. Nutzt man nunmehr, dass erste Auslösemittel, um das zweite Auslösemittel zu führen bzw. zu lagern, kann die Anzahl der notwendigen Lagerelemente reduziert werden. Beispielsweise kann das erste Auslösemittel eine Nut oder eine Ausnehmung aufweisen, auf welcher sich das zweite Auslösemittel abstützt bzw. an welcher das zweite Auslösemittel geführt ist.According to the invention, the second triggering means is guided on the first triggering means. In particular, with increasingly required miniaturization of drive devices and thus also of switching device tripping devices with a gear assembly, it is necessary to position the individual modules closer together. If one uses now that first release means to guide or store the second trigger means, the number of necessary bearing elements can be reduced. For example, the first triggering means may comprise a groove or a recess on which the second triggering means is supported or on which the second triggering means is guided.

Erfindungsgemäß ragt, insbesondere durchsetzt, das zweite Auslösemittel in eine Ausnehmung des ersten Auslösemittels. Die Nutzung einer Ausnehmung, beispielsweise einer Buchse an dem ersten Auslösemittel gestattet es, das zweite Auslösemittel beispielsweise lageveränderlich die Ausnehmung durchsetzen zu lassen. Die Ausnehmung kann auch einer Führung der Auslösemittel aneinander, insbesondere einer Lagerung bzw. Abstützung des zweiten Auslösemittels an dem ersten Auslösemittel dienen. Das zweite Auslösemittel kann in der Ausnehmung, insbesondere einer Buchse, drehbar und/oder verschieblich gelagert sein. So kann das erste Auslösemittel, welches seinerseits an einer Lagervorrichtung abgestützt ist, genutzt werden, um das zweite Auslösemittel zumindest teilweise zu führen, so dass eine separate Lagervorrichtung für das zweite Auslösemittel zumindest vereinfacht gestaltet oder vollständig auf dieses verzichtet werden kann. Beispielsweise kann vorgesehen sein, dass die Ausnehmung eine Linearbewegung des zweiten Auslösemittels ermöglicht, so dass bei der Nutzung zweier linear verschiebbarer Auslösemittel beide parallel, insbesondere koaxial zueinander geführt sind. Es kann weiter von Vorteil sein, wenn das erste Auslösemittel ein rotationssymmetrischer Körper ist und die Ausnehmung koaxial zur Rotationsachse das erste Auslösemittel durchsetzt.According to the invention, in particular, the second triggering means projects into a recess of the first triggering means. The use of a recess, for example a socket on the first triggering means makes it possible for the second triggering means, for example, to be able to pass through the recess in a positionally variable manner. The recess can also serve to guide the triggering means to one another, in particular to support or support the second triggering means on the first triggering means. The second release means may be rotatably and / or displaceably mounted in the recess, in particular a bushing. Thus, the first triggering means, which in turn is supported on a bearing device can be used to guide the second triggering means at least partially, so that a separate storage device for the second triggering means designed at least simplified or can be completely dispensed with this. For example, it can be provided that the recess allows a linear movement of the second triggering means, so that when two linearly displaceable release means are used both are guided parallel to one another, in particular coaxially with one another. It may also be advantageous if the first triggering means is a rotationally symmetrical body and the recess passes through the first triggering means coaxially with the axis of rotation.

Vorteilhaft kann dabei vorgesehen sein, dass das erste Auslösemittel das zweite Auslösemittel zumindest teilweise hohlzylindrisch umgreift.Advantageously, it may be provided that the first release means surrounds the second release means at least partially hollow cylindrical.

Das erste Auslösemittel kann zumindest abschnittsweise hohlzylindrisch ausgeführt sein, wobei der hohlzylindrisch ausgeführte Abschnitt des ersten Auslösemittels das zweite Auslösemittel umgreift. Durch das Umgreifen ist eine Ausnehmung gebildet, welche beispielsweise der Führung des zweiten Auslösemittels dient. Beispielsweise kann das erste Auslösemittel zumindest abschnittsweise hohlzylindrisch ausgebildet sein, wobei die Wandstärke im hohlzylindrischen Abschnitt des ersten Auslösemittels verschieden ausgeführt sein kann. Der hohlzylindrische Abschnitt kann beispielsweise einen kreisringförmigen Querschnitt, einen rechteckigen, ovalen, vieleckigen usw. Querschnitt aufweisen. Vorteilhafterweise sollte das erste Auslösemittel ebenso wie das zweite Auslösemittel rotationssymmetrisch gestaltet sein.The first triggering means may be at least partially hollow cylindrical, wherein the hollow cylindrical executed portion of the first triggering means surrounds the second triggering means. By embracing a recess is formed, which, for example, the leadership of the second triggering means serves. For example, the first release means may be at least partially hollow cylindrical, wherein the wall thickness in the hollow cylindrical portion of the first triggering means may be designed differently. The hollow cylindrical portion may have, for example, an annular cross section, a rectangular, oval, polygonal, etc. cross section. Advantageously, the first triggering means as well as the second triggering means should be rotationally symmetrical.

Weiterhin kann vorteilhaft vorgesehen sein, dass zumindest eines der Auslösemittel als Anker an einem als Tauchspule ausgeführten Antriebselement angeordnet ist.Furthermore, it can advantageously be provided that at least one of the release means is arranged as an armature on a drive element designed as a plunger coil.

Ein Antriebselement dient einem Hervorrufen einer Bewegung eines Auslösemittels. Das Antriebselement wandelt somit eine Energieform in Bewegungsenergie um. Vorteilhafterweise haben sich elektrodynamische Antriebe zur Wandlung elektrischer Energie in mechanische Energie dargestellt, da diese gut steuer- bzw. ansteuerbar sind. Die Verwendung einer Tauchspule als Antriebselement gestattet es, in direkter Weise eine lineare Bewegung auf das als Anker ausgebildete Auslösemittel aufzuprägen. Der Anker kann beispielsweise längs einer Achse linear verschieblich gelagert sein, wobei der Anker in die Tauchspule eintaucht bzw. aus der Tauchspule herausbewegbar ist. Rückstellkräfte können beispielsweise durch Rückstellfedern, die Schwerkraft usw. erzeugt werden, um den Anker in eine Ruheposition zurückzubewegen. Bei einer Betätigung des als Anker ausgeführten Auslösemittels wird dieses aus seiner Ruheposition herausbewegt, um eine Bewegung bzw. Auslösung der Sperrklinke zu bewirken. Dazu wird der Anker mittelbar oder unmittelbar gegen einen Krafteinleitungspunkt der Sperrklinke bewegt. Nach erfolgter Auslösung der Sperrklinke erfolgt eine Rückbewegung des Auslösemittels in seine Ruheposition.A drive element serves to cause a movement of a triggering means. The drive element thus converts an energy form into kinetic energy. Advantageously, electrodynamic drives have been shown for the conversion of electrical energy into mechanical energy, since they are well controllable or controllable. The use of a plunger coil as a drive element makes it possible to directly impart a linear motion to the triggering means designed as an armature. The armature may for example be mounted linearly displaceable along an axis, wherein the armature dips into the plunger coil and is moved out of the plunger coil. Restoring forces may be generated, for example, by return springs, gravity, etc., to return the armature to a rest position. Upon actuation of the triggering means designed as an armature, it is moved out of its rest position in order to bring about a movement or release of the pawl. For this purpose, the anchor is moved indirectly or directly against a force introduction point of the pawl. After the release of the pawl is a return movement of the triggering means in its rest position.

In den Figuren 1, 2, 3 und 5 sind die dargestellten Ausführungsvatianten einer Schaltgeräteauslöseeinrichtung jeweils beispielhaft mit verschiedenen Getriebeanordnungen dargestellt. Die Getriebeanordnungen sind schematisiert und lediglich beispielhaft ausgeführt. Die in den Figuren gezeigten Getriebeanordnungen sowie Elemente daraus sind untereinander austauschbar. In den Figuren sind daher gleichwirkende Baugruppen mit den gleichen Bezugszeichen versehen. Darüber hinaus können auch alternative Ausgestaltungsvarianten einer Getriebeanordnung Verwendung finden. Die Figuren sollen mit den dort dargestellten Getriebeanordnungen einem vereinfachten Verständnis der Wirksamkeit bzw. Nutzung einer Schaltgeräteauslöseeinrichtung dienen.In the FIGS. 1 . 2 . 3 and 5 the illustrated Ausführungsvatianten a switching device tripping device are each exemplified with different gear arrangements. The gear arrangements are schematic and only exemplified. The gear arrangements shown in the figures and elements thereof are interchangeable. In the figures, equivalent components are therefore provided with the same reference numerals. In addition, alternative design variants of a gear arrangement can be used. The figures are to serve with the gear arrangements shown there a simplified understanding of the effectiveness or use of a switching device tripping device.

Die Figur 1 zeigt eine erste Ausführungsvariante einer Schaltgeräteauslöseeinrichtung, in welcher schematisch ein Schaltgerät 1 dargestellt ist. Das Schaltgerät 1 weist ein erstes Kontaktstück 2 sowie ein zweites Kontaktstück 3 auf. Das erste Kontaktstück 2 ist vorliegend ortsfest angeordnet. Das zweite Kontaktstück 3 ist linear verschiebbar ausgestaltet, so dass zwischen dem ersten und dem zweiten Kontaktstück 2, 3 eine relative Bewegbarkeit (vgl. Doppelpfeil) gegeben ist. Das Kontaktstück 3 ist mit einer Speicherfeder 4 gekoppelt, so dass eine Ausschaltbewegung, d. h., eine Trennung der beiden Kontaktstücke 2, 3 voneinander durch Energie getrieben erfolgt, welche der gespannten Speicherfeder 4 entnommen wird.The FIG. 1 shows a first embodiment of a switching device tripping device in which a switching device 1 is shown schematically. The switching device 1 has a first contact piece 2 and a second contact piece 3. The first contact piece 2 is presently arranged stationary. The second contact piece 3 is designed to be linearly displaceable, so that between the first and the second contact piece 2, 3 a relative mobility (see double arrow) is given. The contact piece 3 is coupled to a storage spring 4, so that a switch-off, ie, a separation of the two contact pieces 2, 3 is driven by energy driven, which is the tensioned storage spring 4 is removed.

Die Speicherfeder 4 ist Teil einer Getriebeanordnung zum Erzeugen der Relativbewegung zwischen den Kontaktstücken 2, 3. Die Speicherfeder 4 ist vorliegend in Form einer Schraubenfeder ausgeführt, welche ortsfest gelagert ist. Zum Spannen der Speicherfeder 4 ist ein Elektromotor 5 vorgesehen. Der Elektromotor 5 ist über eine kinematische Kette 6 mit der Speicherfeder 4 verbunden. Die kinematische Kette 6 weist einen Seilzug auf, welcher um eine durch den Elektromotor 5 antreibbare Welle gewunden ist. Somit ist es möglich, durch einen Betrieb des Elektromotors 5 Federspannarbeit an der Speicherfeder 4 zu verrichten und die Speicherfeder 4 zu spannen.The memory spring 4 is part of a gear arrangement for generating the relative movement between the contact pieces 2, 3. The memory spring 4 is in the present case designed in the form of a helical spring, which is mounted stationary. For tensioning the accumulator spring 4, an electric motor 5 is provided. The electric motor 5 is connected via a kinematic chain 6 to the storage spring 4. The kinematic chain 6 has a cable, which is wound around a shaft 5 driven by the electric motor. Thus, it is possible to perform spring tension work on the accumulator spring 4 by operation of the electric motor 5 and to tension the accumulator spring 4.

Folgende Funktionsbeschreibung der Auslösemittel sowie deren Zusammenwirken mit den weiteren Baugruppen trifft auch in analoger Weise für die Ausführungsvarianten der Figuren 2, 3 und 5 zu. Daher sind die Baugruppen, welche die gleiche Funktion ausüben, mit den gleichen Bezugszeichen versehen. Im gespannten Zustand wird die Speicherfeder durch eine Sperrklinke 7 blockiert, so dass ein Entspannen der Speicherfeder 4 nur nach einem Betätigen der Sperrklinke 7 möglich ist. Die Sperrklinke 7 ist als einstückiger Sperrriegel ausgeführt. Ein Entspannen der Speicherfeder 4 erfolgt dabei sprungartig, so dass eine sprungartige Relativbewegung zwischen den beiden Kontaktstücken 2, 3, insbesondere im Zuge eines Ausschaltvorganges erfolgt. Um ein entsprechendes schlagartiges Entspannen der Speicherfeder 4 zu ermöglichen, ist in der kinematischen Kette 6 zu der antreibbaren Welle beispielsweise ein Entkoppelungsmodul vorzusehen, so dass eine bremsende Wirkung von der kinematischen Kette 6 bzw. von dem Elektromotor 5 verhindert ist.The following functional description of the release means and their interaction with the other modules also applies in an analogous manner to the variants of the Figures 2 . 3 and 5 to. Therefore, the assemblies that perform the same function, provided with the same reference numerals. In the tensioned state, the accumulator spring is blocked by a pawl 7, so that a relaxation of the accumulator spring 4 is possible only after an actuation of the pawl 7. The pawl 7 is designed as a one-piece locking bolt. A relaxation of the accumulator spring 4 takes place abruptly, so that a sudden relative movement between the two Contact pieces 2, 3, in particular in the course of a switch-off occurs. In order to allow a corresponding sudden relaxation of the accumulator spring 4, a decoupling module is provided in the kinematic chain 6 to the drivable shaft, for example, so that a braking effect of the kinematic chain 6 and of the electric motor 5 is prevented.

Die Sperrklinke 7 ist linear verschieblich gelagert. Eine lineare Verschiebbarkeit ist dabei in Richtung einer Achse 8 möglich. Beispielhaft ist eine Verschieberichtung der Sperrklinke 7 gemäß der Figur 1 durch in der Sperrklinke 7 angeordnete, in Richtung der Achse 8 verlaufende Langlöcher 9 festgelegt, wobei die Langlöcher 9 von Führungsbolzen 10 durchsetzt sind. Die Führungsbolzen 10 sind jeweils endseitig mit Gewinden ausgestattet, so dass die Führungsbolzen 10 einerseits an einer Grundplatte befestigt werden können und andererseits an den Führungsbolzen 10 mittels auf die jeweiligen Gewinde aufschraubbaren Muttern ein Entfernen der Sperrklinke 7 von den Führungsbolzen 10 verhindert ist.The pawl 7 is mounted linearly displaceable. A linear displacement is possible in the direction of an axis 8. By way of example, a displacement direction of the pawl 7 according to the FIG. 1 determined by arranged in the pawl 7, extending in the direction of the axis 8 slots 9, wherein the slots 9 are penetrated by guide pins 10. The guide pins 10 are each end equipped with threads, so that the guide pins 10 can be fastened on the one hand to a base plate and on the other hand on the guide pin 10 by means of nuts screwed onto the respective thread removal of the pawl 7 is prevented by the guide pin 10.

Zum Antreiben der Sperrklinke 7 sind ein erstes Auslösemittel 11 sowie ein zweites Auslösemittel 12 vorgesehen. Die beiden Auslösemittel 11, 12 sind bolzenförmig ausgeführt, wobei die Bolzen der Auslösemittel 11, 12 jeweils in einem Eisenkern 13 verschieblich geführt sind. Die Eisenkerne 13 führen die jeweiligen Auslösemittel 11, 12 parallel zur Achse 8, wobei die Auslösemittel 11, 12 linear verschieblich parallel der Achse 8 angeordnet sind. Die Eisenkerne 13 können die Funktion eines die Auslösemittel 11, 12 umschließenden Gehäuses wahrnehmen. Die beiden Auslösemittel 11, 12 sind dabei jeweils als Tauchanker einer Tauchspule 14 ausgebildet, die als Antriebselement dient. Eine Tauchspule 14 stellt mit einem Anker ein elektrodynamisches Antriebselement dar. Die jeweiligen Auslösemitteln 11, 12 dienen als Anker der jeweiligen Tauchspulen 14. In der Figur 1 ist die Lage der Auslösemittel 11, 12 in Ruheposition dargestellt. Mittels jeweils einer koaxial zu den Auslösemitteln 11, 12 angeordneten Rückstellfeder 15, werden die beiden Auslösemittel 11, 12 jeweils von zu der Sperrklinke 7 fort in ihre Ruhepositionen gepresst. Statt einer Nutzung einer Rückstellfeder 15 zur Erzeugung einer Rückstellkraft können auch alternative Vorrichtungen genutzt werden. Beispielsweise können die Auslösemittel 11, 12 durch ihre Gewichtskraft in ihre Ruhepositionen "zurückfallen". Ein Widerlager für die von der Rückstellfeder 15 ausgehende Kraft und Anschläge für Endlagen der Auslösemittel 11, 12 werden durch den jeweiligen Eisenkern 13 zur Verfügung gestellt. Die Auslösemittel 11, 12 sind an ihren von der Sperrklinke 7 abgewandten Ende jeweils mit einer radial ausladenden Schulter ausgestattet, welche jeweils wechselweise an den Anschlägen der Endlagen des jeweiligen Eisenkerns 13 anliegen.For driving the pawl 7, a first trigger means 11 and a second trigger means 12 are provided. The two release means 11, 12 are bolt-shaped, wherein the bolts of the release means 11, 12 are guided displaceably in each case in an iron core 13. The iron cores 13 guide the respective release means 11, 12 parallel to the axis 8, wherein the release means 11, 12 are arranged linearly displaceable parallel to the axis 8. The iron cores 13 can perform the function of a housing enclosing the triggering means 11, 12. The two release means 11, 12 are each formed as a plunger armature of a plunger coil 14, which serves as a drive element. A plunger coil 14 is an electrodynamic drive element with an armature. The respective release means 11, 12 serve as anchors of the respective plunger coils 14. In the FIG. 1 is the location of the release means 11, 12 shown in rest position. By means of a respective coaxial with the release means 11, 12 arranged return spring 15, the two release means 11, 12 are each pressed to the pawl 7 in their rest positions. Instead of using a return spring 15 to generate a restoring force and alternative devices can be used. For example, the release means 11, 12 can "fall back" by their weight in their rest positions. An abutment for the outgoing of the return spring 15 force and stops for end positions of the release means 11, 12 are provided by the respective iron core 13. The release means 11, 12 are provided at their end remote from the pawl 7 each end with a radially projecting shoulder, which abut each other alternately to the attacks of the end positions of the respective iron core 13.

Bei einer Bestromung der Tauchspulen 14 erfolgt eine magnetische Kraftwirkung auf die jeweiligen Auslösemittel 11, 12, wodurch die Auslösemittel 11, 12 gegen die Kraft der jeweiligen Rückstellfeder 15 in Richtung der Sperrklinke 7 bewegt werden. Die Auslösemittel 11, 12 vollziehen jeweils einen linearen Hub in Richtung der Achse 8, schlagen an der Sperrklinke 7 an Krafteinleitungspunkten an und verschieben die Sperrklinke 7 in Richtung der Achse 8. In der Folge gibt die Sperrklinke 7 die gespannte Speicherfeder 4 frei. Die Speicherfeder 4 entspannt sich sprungartig und öffnet sprungartig die Schaltstrecke zwischen den beiden Kontaktstücken 2, 3. Nach erfolgter Freigabe der Speicherfeder 4 endet die Bestromung der Tauchspulen 14. Die beiden Auslösemittel 11, 12 werden durch die Kraft der jeweiligen Rückstellfeder 15 in ihre Ruhepositionen zurückbewegt. Weiterhin wird durch eine Sperrklinkenrückstellfeder 17 auch eine Rückbewegung der Sperrklinke 7 bewirkt, so dass die Sperrklinke 7 wiederum bereit ist, nach einem Spannen der Speicherfeder 4 die gespannte Speicherfeder 4 festzuhalten, um nach einem Auslösen durch die Auslösemittel 11, 12 diese Speicherfeder 4 freizugeben und eine Schaltbewegung bzw. Relativbewegung zwischen den Kontaktstücken 2, 3 zu erzeugen.When energizing the plunger coils 14 is a magnetic force acting on the respective release means 11, 12, whereby the release means 11, 12 are moved against the force of the respective return spring 15 in the direction of the pawl 7. The release means 11, 12 each perform a linear stroke in the direction of the axis 8, strike the pawl 7 at force application points and move the pawl 7 in the direction of the axis 8. As a result, the pawl 7, the tensioned storage spring 4 free. The memory spring 4 relaxes abruptly and suddenly opens the contact gap between the two contact pieces 2, 3. After the release of the memory spring 4, the energization of the plunger coils 14 ends. The two release means 11, 12 are moved back by the force of the respective return spring 15 in their rest positions , Furthermore, by a pawl return spring 17 and a return movement of the pawl 7 causes, so that the pawl 7 is again ready to hold the tensioned memory spring 4 after a tensioning of the accumulator spring 4, after release by the release means 11, 12 release this accumulator spring 4 and to generate a switching movement or relative movement between the contact pieces 2, 3.

Das erste Auslösemittel 11 sowie das zweite Auslösemittel 12 verfügen jeweils über unabhängig voneinander wirkende Antriebselemente in Form von Tauchspulen 14, so dass bei einem Ausfall einer der Tauchspulen 14 oder einem Blockieren eines der Auslösemittel 11, 12 das jeweils andere nicht gestörte Auslösemittel 11, 12 bzw. die nicht gestörte Tauchspule 14 eine Betätigung der Sperrklinke 7 vollziehen kann. Die beiden Auslösemittel 11, 12 wirken unabhängig voneinander auf dieselbe Sperrklinke 7.The first triggering means 11 and the second triggering means 12 each have independently acting drive elements in the form of plunger coils 14, so that in the event of failure of one of the plunger coils 14 or blocking one of the triggering means 11, 12 the respective other non-disturbed triggering means 11, 12 or the undisturbed plunger coil 14 can perform an actuation of the pawl 7. The two release means 11, 12 act independently on the same pawl. 7

Die Figur 2 zeigt die aus der Figur 1 bekannte Schaltgeräteauslöseeinrichtung, wobei die Ausgestaltung der Sperrklinke variiert. Wiederum ist die Verwendung einer Speicherfeder 4 vorgesehen, welche mittels eines Elektromotors 5 über eine kinematische Kette 6 gespannt werden kann, wobei ein Blockieren der gespannten Speicherfeder 4 mittels einer Sperrklinke 7 vorgesehen ist. In der Figur 2 ist die entspannte Position der Speicherfeder 4 dargestellt, wobei die Kontaktstücke 2, 3 in geöffneter Position dargestellt sind. Strichpunktiert ist an der Speicherfeder 4 eine gestreckte Lage der Speicherfeder 4 im gespannten Zustand symbolisiert, wobei die Sperrklinke 7 die Speicherfeder 4 im gespannten Zustand blockiert. Im Folgenden soll lediglich auf die alternative Ausgestaltung einer Sperrklinke 7 eingegangen werden. Die Sperrklinke 7 weist vorliegend einen zweiarmigen ortsfest gelagerten Hebel 18 auf. Der ortsfeste Hebel 18 ist um einen ortsfesten Drehpunkt schwenkbar, so dass die Sperrklinke 7 eine gespannte Speicherfeder 4 freigeben kann. Mit einem Arm des ortsfesten Hebels 18 ist ein Pleuel 19 verbunden. Das Pleuel 19 verbindet den ortsfesten Hebel 18 mit einem Winkelhebel 20. Der Winkelhebel 20 ist ortsfest gelagert, wobei der Winkelhebel 20 von einem ersten sowie mit einem zweiten Auslösemittel 11, 12 bewegbar ist. Krafteinleitungspunkte der beiden Auslösemittel 11, 12 befinden sich am Winkelhebel 20 der Sperrklinke 7. Durch eine Bewegung der Auslösemittel 11, 12 wird eine Bewegung der Sperrklinke 7 bewirkt, die analog zu der in Figur 1 beschriebenen Ausführungsvariante ein Entspannen einer gespannten Speicherfeder 4 bewirkt. Die zum Bewegen der Auslösemittel 11, 12 nötigen Baugruppen sind analog zu den Baugruppen der Figur 1 ausgeführt und folglich mit den gleichen Bezugszeichen versehen. Im Unterschied zur Figur 1 ist die Sperrklinke 7 in Form einer Hebelkette ausgeführt.The FIG. 2 shows the from the FIG. 1 known switching device triggering device, wherein the configuration of the pawl varies. Again, the use of a memory spring 4 is provided, which can be tensioned by means of an electric motor 5 via a kinematic chain 6, wherein a blocking of the tensioned storage spring 4 is provided by means of a pawl 7. In the FIG. 2 the relaxed position of the storage spring 4 is shown, wherein the contact pieces 2, 3 are shown in the open position. Dash-dotted on the accumulator spring 4 is an extended position of the accumulator spring 4 symbolized in the tensioned state, wherein the pawl 7 blocks the accumulator spring 4 in the tensioned state. In the following, only the alternative embodiment of a pawl 7 will be discussed. The pawl 7 in this case has a two-armed stationary mounted lever 18. The fixed lever 18 is pivotable about a fixed pivot point, so that the pawl 7 can release a tensioned storage spring 4. With one arm of the stationary lever 18, a connecting rod 19 is connected. The connecting rod 19 connects the stationary lever 18 with an angle lever 20. The angle lever 20 is fixedly mounted, wherein the angle lever 20 of a first and with a second release means 11, 12 is movable. Force application points of the two release means 11, 12 are located on the angle lever 20 of the pawl 7. By a movement of the release means 11, 12, a movement of the pawl 7 is effected, which analogous to the in FIG. 1 described embodiment causes a relaxation of a tensioned accumulator spring 4. The ones for moving the release means 11, 12 necessary assemblies are analogous to the modules of FIG. 1 executed and therefore provided with the same reference numerals. In contrast to FIG. 1 the pawl 7 is designed in the form of a lever chain.

In den Figuren 3 und 5 zeigen jeweils prinzipielle Darstellungen eine Verklinkungsmechanik sowie der Getriebeanordnung. Gleichwirkende Baugruppen sind mit den gleichen Bezugszeichen, wie in den Figuren 1 und 2, versehen. Da die Funktion analog der Figuren 1 und 2 erfolgt, wird lediglich die Art und Weise der Ausgestaltung von Auslösemitteln und Antriebsmitteln zu den Figuren 3, 4 und 5 näher beschrieben.In the Figures 3 and 5 show in each case basic representations a Verklinkungsmechanik and the gear arrangement. Gleichwirkende assemblies are denoted by the same reference numerals as in the FIGS. 1 and 2 , Mistake. Since the function is analogous to FIGS. 1 and 2 takes place, only the way the design of release means and drive means to the Figures 3 . 4 and 5 described in more detail.

In der Figur 3 ist ein Krafteinleitungspunkt zweier Auslösemittel 11, 12 an einer Sperrklinke 7 dargestellt. Die Sperrklinke 7 ist um einen ortsfesten Lagerpunkt schwenkbar. Ein erstes Auslösemittel 11 sowie ein zweites Auslösemittel 12 sind axial hintereinander liegend angeordnet, wobei die beiden Auslösemittel 11, 12 jeweils bolzenförmig ausgestaltet sind. Dabei ist vorgesehen, dass das zweite Auslösemittel 12 unter Zwischenlage des ersten Auslösemittels 11 gegen die Sperrklinke 7 bewegbar ist, um die Sperrklinke 7 zu schwenken. Entsprechend ist vorgesehen, dass die jeweils in Form von Stößeln ausgeführten Auslösemittel 11, 12 derart hintereinander liegend angeordnet sind, dass der Stößel des zweiten Auslösemittels 12 bei einer Bewegung von seiner Ruhelage in eine Auslöselage gegen das erste Auslösemittel 11 getrieben ist und somit beispielsweise bei Ausfall der Tauchspule 14 des ersten Auslösemittels unter Zwischenlage des ersten Auslösemittels 11 die Sperrklinke 7 betätigt. Entsprechend ist vorgesehen, dass in dem Eisenkern 13 des ersten Auslösemittels 11 eine koaxial zur Achse 8 ausgebildete Ausnehmung vorgesehen ist, durch welche das zweite Auslösemittel 12 in das Innere des Eisenkerns 13 des ersten Auslösemittels 11 hineinragen kann, so dass eine Kraftwirkung von dem zweiten Auslösemittel 12 auf das erste Auslösemittel 11 ausgeübt werden kann. Sofern beide Auslösemittel 11, 12 durch die Tauchspulen 14 in eine Bewegung versetzt werden, so addieren sich die von den beiden Auslösemitteln 11, 12 ausgehenden Kräfte zum Betätigen der Sperrklinke 7. Die Kraftwirkung, welche durch eine der Tauchspulen 14 erzeugt werden kann, ist dabei jedoch derart bemessen, dass auch bei Ausfall einer der Tauchspulen 14 eine zum Betätigen der Sperrklinke 7 ausreichende Kraftwirkung durch eine einzige Tauchspule 14 hervorgerufen werden kann. Auch bei Ausfall der Tauchspule 14 des ersten Auslösemittels 11 entsteht eine Kraftwirkung auf das zweite Auslösemittel 12 und eine Verschiebung des ersten Auslösemittels 11 in Richtung der Achse 8 auf die Sperrklinke 7 zu. Das zweite Auslösemittel 12 bewegt das erste Auslösemittel 11 dazu in Richtung der Achse 8 gegen die Sperrklinke 7 und unter Zwischenlage des ersten Auslösemittels 11 ist eine Betätigung der Sperrklinke 7 durch das zweite Auslösemittel 12 bewirkt. Im umgekehrten Falle bei einem Ausfall der Tauchspule 14 des zweiten Auslösemittels 12, verbleibt das zweite Auslösemittel 12 in Ruhe und lediglich das erste Auslösemittel 11 bewegt die Sperrklinke 7. Die beiden Auslösemittel 11, 12 wirken auf denselben Krafteinleitungspunkt (mittelbar bzw. unmittelbar) an der Sperrklinke 7 ein.In the FIG. 3 is a force application point of two release means 11, 12 shown on a pawl 7. The pawl 7 is pivotable about a fixed bearing point. A first triggering means 11 and a second triggering means 12 are arranged axially one behind the other, wherein the two triggering means 11, 12 are respectively designed bolt-shaped. It is provided that the second release means 12 with the interposition of the first triggering means 11 against the pawl 7 is movable to pivot the pawl 7. Accordingly, it is provided that the respectively executed in the form of plungers release means 11, 12 are arranged one behind the other such that the plunger of the second trigger means 12 is driven in a movement from its rest position into a release position against the first triggering means 11 and thus, for example, in case of failure the plunger coil 14 of the first triggering means with the interposition of the first triggering means 11, the pawl 7 is actuated. Accordingly, it is provided that in the iron core 13 of the first triggering means 11 a coaxial with the axis 8 formed recess is provided, through which the second triggering means 12 may protrude into the interior of the iron core 13 of the first triggering means 11, so that a force from the second triggering means 12 can be exercised on the first triggering means 11. If both release means 11, 12 are set in motion by the plunger coils 14, then the total of The force effect, which can be generated by one of the plunger coils 14, however, is dimensioned such that even if one of the plunger coils 14 fails, one for actuating the pawl 7 sufficient force by a single plunger coil 14 can be caused. Even if the plunger coil 14 of the first triggering means 11 fails, a force is exerted on the second triggering means 12 and a displacement of the first triggering means 11 in the direction of the axis 8 toward the pawl 7. The second triggering means 12 moves the first triggering means 11 toward the axis 8 against the pawl 7 and with the interposition of the first triggering means 11, an actuation of the pawl 7 is effected by the second triggering means 12. In the reverse case in case of failure of the plunger coil 14 of the second trigger means 12, the second trigger means 12 remains at rest and only the first trigger means 11 moves the pawl 7. The two trigger means 11, 12 act on the same force application point (indirectly or directly) on the Pawl 7 a.

Im Folgenden wird anhand der Figuren 4 und 5 ein modularer Aufbau von Auslösemitteln sowie Tauchspulen und Eisenkernen näher beschrieben.The following is based on the FIGS. 4 and 5 a modular design of tripping devices and immersion coils and iron cores described in more detail.

Die Figur 4 zeigt den Aufbau der Eisenkerne 13 eines ersten und eines zweiten Auslösemittels 11, 12. Die Eisenkerne 13 sowie die Antriebsmittel für das erste und das zweite Auslösemittel 11, 12 sind jeweils gleichartig aufgeführt. Daher wird im Folgenden beispielhaft anhand der Figur 4 der Aufbau von Eisenkern 13 und Antriebsmittel 14 des ersten Auslösemittels 11 exemplarisch beschrieben. Der Eisenkern 13 ist rotationssymmetrisch zu einer Längsachse 8 angeordnet und weist ein erstes Teilelement 13a sowie ein zweites Teilelement 13b auf. Die beiden Teilelemente 13a, 13b sind aneinander zugewandten Stirnseiten kontaktiert, wobei die Stirnseiten lotrecht zur Achse 8 ausgerichtet sind. In den einander zugewandten Stirnseiten sind ringförmig umlaufende Ausnehmungen eingebracht, die der Aufnahme einer zwischen den beiden Teilelementen 13a, 13b des Eisenkerns 13 liegenden Tauchspule 14 dienen. Die Tauchspule 14 ist so in dem Eisenkern 13 eingebettet und koaxial zur Achse 8 ausgerichtet. Der Eisenkern 13, insbesondere dessen erstes Teilelement 13a dient einer Lenkung eines durch die Tauchspule 14 erzeugbaren Magnetfeldes.The FIG. 4 shows the structure of the iron cores 13 of a first and a second triggering means 11, 12. The iron cores 13 and the drive means for the first and the second triggering means 11, 12 are each identically listed. Therefore, in the following example using the FIG. 4 the structure of iron core 13 and drive means 14 of the first triggering means 11 described by way of example. The iron core 13 is arranged rotationally symmetrical to a longitudinal axis 8 and has a first sub-element 13a and a second sub-element 13b. The two sub-elements 13a, 13b are contacted to mutually facing end faces, wherein the end faces are aligned perpendicular to the axis 8. In the facing end faces are annular circumferential recesses introduced, which serve to receive a lying between the two sub-elements 13a, 13b of the iron core 13 immersion coil 14. The plunger coil 14 is embedded in the iron core 13 and aligned coaxially with the axis 8. The iron core 13, in particular its first sub-element 13a, serves to guide a magnetic field that can be generated by the plunger coil 14.

In Richtung der Achse 8 ist der Eisenkern 13 zentrisch von einer durchgehenden Ausnehmung durchsetzt, die im Wesentlichen zylinderförmige Innenmantelflächen aufweist, wobei mehrere vorspringende Schultern zur Ausbildung von Anschlägen für das erste Auslösemittel 11 vorgesehen sind. Das erste Auslösemittel 11 ist vorliegend als Hohlzylinder ausgebildet, welcher gleitend in dem ersten Teilelement 13a des Eisenkerns 13 gelagert ist. Somit kann das erste Auslösemittel 11 in Richtung der Achse 8 verschoben werden. An seinem innerhalb des Eisenkerns 13 liegenden Ende ist das erste Auslösemittel 11 radial erweitert ausgebildet, so dass vorspringende Schultern gebildet sind, die an gegengleichen Anschlägen des Eisenkerns 13 in den Endpositionen z. B. in einer Ruheposition anliegen. Die radiale Erweiterung des ersten Auslösemittels 11 ist hohlzylindrisch ausgeformt, wobei eine Außenmantelfläche der radialen Erweiterung gleitend in einer gegengleichen Innenmantelfläche des zweiten Teilelementes 13b des Eisenkerns 13 geführt ist. Durch die radiale Erweiterung ist am ersten Auslöseelement 11 die freie Bewegbarkeit des ersten Auslösemittels 11 in Richtung der Achse 8 begrenzt. Somit kann zum einen eine Ruheposition des ersten Auslösemittels 11 in dem Eisenkern 13 eingenommen werden, wobei das erste Auslösemittel 11 in seiner Ruheposition nahezu vollständig in den Eisenkern 13 eingezogen ist. Um das erste Auslösemittel 11 sicher in seiner Ruheposition zu halten, ist eine Rückstellfeder 15 vorgesehen, welche die radiale Erweiterung des ersten Auslösemittels 11 abgestützt am ersten Teilelement 13a des Eisenkerns 13 gegen eine vorspringende Schulter des zweiten Teilelementes 13b des Eisenkerns 13 presst. Somit ist es möglich, dass bei einer Bestromung der Tauchspule 14 das erste Auslösemittel 11 nach Art eines Tauchankers in die Tauchspule 14 gegen die Kraft der Rückstellfeder 15 eintaucht, wobei das erste Auslösemittel 11 stirnseitig aus dem Eisenkern 13 hervortritt und nach einem Beenden der Bestromung der Tauchspule 14 durch die Rückstellkraft der gespannten Rückstellfeder 15 eine Rückbewegung des ersten Auslösemittels 11 in seine Ruheposition erfolgt. Wie bereits zur Figur 1 ausgeführt kann auf eine Rückstellfeder verzichtet werden bzw. eine alternative Vorrichtung genutzt werden.In the direction of the axis 8 of the iron core 13 is centrally penetrated by a through recess, which has substantially cylindrical inner circumferential surfaces, wherein a plurality of projecting shoulders are provided for the formation of stops for the first release means 11. In the present case, the first triggering means 11 is designed as a hollow cylinder which is slidably mounted in the first subelement 13a of the iron core 13. Thus, the first triggering means 11 can be moved in the direction of the axis 8. At its end located within the iron core 13, the first triggering means 11 is formed radially widened, so that projecting shoulders are formed on z. B. abut in a rest position. The radial extension of the first triggering means 11 is formed as a hollow cylinder, wherein an outer circumferential surface of the radial extension is slidably guided in a diametrically opposed inner circumferential surface of the second partial element 13b of the iron core 13. Due to the radial expansion, the free mobility of the first triggering means 11 in the direction of the axis 8 is limited on the first triggering element 11. Thus, on the one hand a rest position of the first triggering means 11 can be taken in the iron core 13, wherein the first triggering means 11 is retracted almost completely in its rest position in the iron core 13. In order to securely hold the first triggering means 11 in its rest position, a return spring 15 is provided, which supports the radial extension of the first triggering means 11 on the first subelement 13a of the iron core 13 against a protruding shoulder of the second subelement 13b of the iron core 13. Thus, it is possible that when energizing the plunger coil 14, the first Triggering means 11 immersed in the plunger coil 14 against the force of the return spring 15 in the manner of a plunger, the first triggering means 11 emerges from the front end of the iron core 13 and after stopping the energization of the plunger 14 by the restoring force of the tensioned return spring 15, a return movement of the first triggering means 11 takes place in its rest position. As already for FIG. 1 executed can be dispensed with a return spring or an alternative device can be used.

Das erste Auslösemittel 11 ist mit einer Ausnehmung 21 ausgestattet, welche sich koaxial zur Achse 8 erstreckt und das erste Auslösemittel 11 vollständig durchsetzt. An seinem von der radialen Erweiterung abgewandten Ende ist das erste Auslösemittel 11 mit einem Innengewinde 22 versehen. Durch die Ausnehmung 21 ist das erste Auslösemittel 11 in Form einer Buchse ausgestaltet, so dass die Buchse beispielsweise einer Führung oder einer Lagerung beispielsweise eines zweiten Auslösemittels 12 dienen kann.The first triggering means 11 is provided with a recess 21 which extends coaxially to the axis 8 and the first triggering means 11 passes completely. At its end facing away from the radial extension of the first trigger means 11 is provided with an internal thread 22. Through the recess 21, the first triggering means 11 is designed in the form of a socket, so that the socket can serve for example a guide or storage, for example, a second triggering means 12.

Das zweite Auslösemittel 12 weist einen Grundkörper auf, welcher seiner Konstruktion nach dem ersten Auslösemittel 11 entspricht. In ein Innengewinde 22 der Ausnehmung 21 des Grundkörpers des zweiten Auslösemittels 12 ist ein Stab 23 eingeschraubt, welcher das zweite Auslösemittel 12 komplettiert. Der Stab 23 ist dabei ebenso wie der Grundkörper des zweiten Auslösemittels 12 koaxial zur Achse 8 ausgerichtet. Der Stab 23 weist einen derartigen Querschnitt auf, dass dieser in die Ausnehmung 21 des ersten Auslösemittels 11 nach Art einer Spielpassung einführbar ist, so dass der Stab 23 in der Ausnehmung 21 des ersten Auslösemittels verschieblich gelagert ist. Somit ist eine Lagerbuchse an dem ersten Auslösemittel 11 für das zweite Auslösemittel 12 gegeben.The second triggering means 12 has a base body which corresponds in construction to the first triggering means 11. In a female thread 22 of the recess 21 of the main body of the second triggering means 12, a rod 23 is screwed, which completes the second triggering means 12. The rod 23 is aligned as well as the main body of the second triggering means 12 coaxial with the axis 8. The rod 23 has a cross-section such that it can be introduced into the recess 21 of the first triggering means 11 in the manner of a clearance, so that the rod 23 is displaceably mounted in the recess 21 of the first triggering means. Thus, a bearing bush is provided on the first triggering means 11 for the second triggering means 12.

Somit sind ein erstes sowie ein zweites Auslösemittel 11, 12 ausgebildet, welche jeweils eine lineare Bewegung abgeben und jeweils auf dieselbe Sperrklinke einwirken bzw. diese antreiben, wobei die beiden Auslösemittel 11, 12 koaxial zueinander ausgerichtet sind, d. h., das erste Auslösemittel 11 umgreift das zweite Auslösemittel 12 zumindest abschnittsweise außenmantelseitig, wobei jedes der beiden Auslösemittel 11, 12 über eine separate Antriebseinrichtung antreibbar ist.Thus, a first and a second trigger means 11, 12 are formed, which each deliver a linear movement and each act on the same pawl or drive, wherein the two trigger means 11, 12 coaxial with each other are aligned, ie, the first release means 11 surrounds the second release means 12 at least partially outer jacket side, wherein each of the two release means 11, 12 is drivable via a separate drive means.

Die Figur 5 zeigt die aus der Figur 4 bekannte Anordnung mit Stab 23, welcher die Buchse des ersten Auslösemittels 11 durchsetzt. Die beiden Eisenkerne 13 der beiden Auslösemittel stoßen in Richtung der Achse 8 bündig aneinander und sind fluchtend zueinander ausgerichtet. Der Stab 23 bzw. das zweite Auslösemittel 12 ist über den Stab 23 des zweiten Auslösemittels 12 an dem ersten Auslösemittel 11 gelagert. Die beiden Auslösemittel 11, 12 sind an einer Stirnseite eines der Eisenkerne 13, hier des Eisenkerns 13 des ersten Auslösemittels 11, der Sperrklinke 7 zugewandt, wobei jedes der Auslösemittel 11, 12 direkt auf die Sperrklinke 7 einwirken kann. Somit ist die Möglichkeit gegeben, dass sowohl das erste Auslösemittel 11 als auch das zweite Auslösemittel 12 unabhängig vom Zustand des jeweils anderen Auslösemittels bzw. dessen Tauchspulen, Rückstellfedern usw. eine Bewegung der Sperrklinke 7 bewirken kann. Das erste sowie das zweite Auslösemittel 11, 12 wirken an nahezu demselben Krafteinleitungspunkt der Sperrklinke 7 auf diese ein. So sind Verkantungen und Verkippungen vermieden, die Sperrklinke 7 kann eine Schwenkbewegung vollziehen.The FIG. 5 shows the from the FIG. 4 known arrangement with rod 23, which passes through the socket of the first triggering means 11. The two iron cores 13 of the two triggering means abut each other in the direction of the axis 8 and are aligned with each other. The rod 23 or the second triggering means 12 is mounted on the first triggering means 11 via the rod 23 of the second triggering means 12. The two triggering means 11, 12 are on a front side of one of the iron cores 13, here the iron core 13 of the first triggering means 11, the pawl 7 faces, each of the triggering means 11, 12 can act directly on the pawl 7. Thus, there is the possibility that both the first triggering means 11 and the second triggering means 12 can cause a movement of the pawl 7 regardless of the state of the respective other triggering means or its plunger coils, return springs, etc. The first and the second trigger means 11, 12 act on almost the same force introduction point of the pawl 7 on this. So tilting and tilting are avoided, the pawl 7 can perform a pivoting movement.
