Einschaltenergiespeichervorrichtungswitch-on
Die Erfindung betrifft eine Einschaltenergiespeichervorrichtung für einen Leistungsschalter, wobei ein Einschaltenergiespeicher an einem ersten Ende gehalten ist und an einem zweiten Ende mit einem Exzenter einer Spannvorrichtung verbunden ist, mit der rückbewegungsbegrenzende Mittel zusammenwirken.The invention relates to a turn-on energy storage device for a circuit breaker, wherein a turn-on energy storage is held at a first end and connected at a second end to an eccentric of a tensioning device, cooperate with the Rückbewegungsbegrenzende means.
Eine derartige Einschaltenergiespeichervorrichtung für einen Leistungsschalter ist aus der DE 195 03 679 Cl bekannt. Eine Einschaltfeder als Einschaltenergiespeicher ist an ihrem ersten Ende fixiert und an ihrem zweiten Ende mit einem an einer Spann- und Schaltwelle angeordneten Exzenter verbunden. In einer Spannvorrichtung für die Einschaltfeder ist eine Rücklaufsperre als rückbewegungsbegrenzendes Mittel ausgebildet; die Rücklaufsperre weist ein an einer Buchse einer Aufzugs- welle sowie an einer Wand der Spannvorrichtung angeordnete Anschlagelemente und ein Freilauflager auf. Bei einem Spannvorgang ist dabei die Buchse über das Freilauflager von der Aufzugswelle entkoppelt. Nach einem Einschaltvorgang des Leistungsschalters, bei dem die in der Einschaltfeder gespeicherte Energie zur Drehung der Schaltwelle verwendet wird, kann sich aufgrund der Bewegungsenergie die Bewegungsrichtung der Schaltwelle und des Endes der Einschaltfeder umkehren. Bei einer solchen Umkehr wird durch das Freilauflager die Buchse so lange gedreht, bis das an der Buchse angeordnete Anschlagelement am an der Wand angeordneten Anschlagelement anliegt. Sind die beiden Anschlagelemente miteinander in Kontakt, wird eine weitere Bewegung verhindert. Ein derartiges Freilauflager ist ein Präzisionsteil und daher sehr kostenintensiv. Aufgabe der vorliegenden Erfindung ist es, einen Einschalt- energiespeicher der eingangs erwähnten Art auszubilden, der einen einfachen und kostengünstigen Aufbau ermöglicht.Such a power-on energy storage device for a circuit breaker is known from DE 195 03 679 Cl. A switch-on spring as a switch-on energy storage is fixed at its first end and connected at its second end with a arranged on a clamping and switching shaft eccentric. In a tensioning device for the switch-on spring, a backstop is designed as a back movement-limiting means; the backstop has a stop element arranged on a bushing of an elevator shaft and on a wall of the tensioning device, and a freewheel bearing. In a clamping operation while the socket is decoupled via the freewheel bearing of the elevator shaft. After a switch-on of the circuit breaker, in which the energy stored in the closing spring is used to rotate the switching shaft, due to the kinetic energy, the direction of movement of the switching shaft and the end of the closing spring can be reversed. In such a reversal, the sleeve is rotated by the freewheel bearing until the arranged on the bush stop element abuts against the wall arranged stop element. If the two stop elements in contact with each other, further movement is prevented. Such a freewheel bearing is a precision part and therefore very expensive. Object of the present invention is to form a switch-on energy storage of the type mentioned, which allows a simple and inexpensive construction.
Gelöst wird diese Aufgabe dadurch, dass erfindungsgemäß die Mittel einen am ersten Ende des Einschaltenergiespeichers angeordneten Klinkenmechanismus aufweisen. Eine solche Anordnung ist in vorteilhafter Weise einfach, kostengünstig und gleichzeitig verschleißarm, weil eine Rücklaufbewegung des Einschaltenergiespeichers allein durch den am ersten Ende des Einschaltenergiespeichers angeordneten Klinkenmechanismus begrenzt bzw. verhindert wird.This object is achieved in that, according to the invention, the means have a latch mechanism arranged at the first end of the switch-on energy store. Such an arrangement is advantageously simple, inexpensive and at the same time wear-resistant, because a return movement of the switch-on energy storage is limited or prevented solely by the latch mechanism arranged at the first end of the switch-on energy store.
In einer zweckmäßigen Weiterbildung enthalten die Mittel ein den Klinkenmechanismus auslösendes Führungsteil, mit dem das erste Ende des Einschaltenergiespeichers an einer festen Achse mittels eines im Führungsteil ausgebildeten Langlochs beweglich gelagert und welches mit dem zweiten Ende des Einschaltenergiespeichers verbunden . ist . Vorteilhaft bei einer solchen Anordnung ist, dass aufgrund des exzentrisch gelagerten zweiten Endes des Einschaltenergiespeichers und des in einem Langloch gelagerten Führungsteils eine Bewegungsbahn des Führungsteils hinsichtlich seines freien Endes während eines Einschaltvorganges sich von einer Bewegungsbahn nach dem Einschaltvorgang unterscheidet, so dass mit dem Klinkenmechanismus einerseits ein Spannen des Einschaltenergiespeichers erfolgt und andererseits eine Rückbewegung begrenzt wird.In an expedient development, the means comprise a ratchet mechanism triggering guide member, with which the first end of the switch energy storage on a fixed axis by means of an elongated hole formed in the guide member and which is connected to the second end of the switch energy storage. is. An advantage of such an arrangement is that due to the eccentrically mounted second end of the switch energy storage and mounted in a slot guide part of a movement path of the guide member with respect to its free end during a switch-on differs from a trajectory after the switch, so that with the latch mechanism on the one hand Clamping the switch-on energy storage takes place and on the other hand, a return movement is limited.
In einer bevorzugten Ausführungsform weist der Klinkenmechanismus eine um die feste Achse zwischen einer ersten und einer zweiten Position drehbar bewegliche Klinke auf, an welcher ein Federelement angreift. Mit einer solchen Klinke lässt sich der Klinkenmechanismus einfach aufbauen. In einer bevorzugten Ausführungsform sind die feste Achse und das Federelement an einem Befestigungselement gehalten. Bei einer solchen Anordnung kann die Klinke mittels des Federele- ments in einfacher Weise zwischen ihrer ersten und ihrer zweiten Position um die Achse verschwenkt werden.In a preferred embodiment, the pawl mechanism has a pawl rotatably movable about the fixed axis between a first and a second position, to which a spring element engages. With such a pawl, the latch mechanism can be easily set up. In a preferred embodiment, the fixed axis and the spring element are held on a fastening element. In such an arrangement, the pawl can be easily pivoted about its axis by means of the spring element between its first and its second position.
In zweckmäßiger Ausgestaltung ist am Führungsteil ein Anschlagelement vorgesehen, das mit einer Spannaussparung an der Klinke zusammenwirkt. Durch die Anordnung des Anschlägelements am Führungsteil und das Zusammenwirken mit der Spannaussparung wird eine einfache Möglichkeit zur Auslenkung der Klinke aus ihrer ersten in ihre zweite Position realisiert .In an advantageous embodiment, a stop element is provided on the guide part, which cooperates with a clamping recess on the pawl. The arrangement of the Anschlägelements on the guide member and the interaction with the clamping recess a simple way to deflect the pawl from its first to its second position is realized.
In weiterer Fortbildung weist die Klinke eine Arretieraussparung auf. Bei einer Rückbewegung des Einschaltenergiespeichers nach einem Einschaltvorgang greift das Anschlagelement in die Arretieraussparung ein, so dass eine Rückbewegungsbe- grenzung in einfacher und wirksamer Weise ausgebildet ist.In a further development, the pawl on a locking recess. Upon a return movement of the switch-on energy storage device after a switch-on process, the stop element engages in the locking recess, so that a Rückbewegungsbe- limitation is formed in a simple and effective manner.
Die Erfindung wird im Folgenden anhand der Zeichnungen und eines Ausführungsbeispiels mit Bezug auf die Figuren näher erläutert .The invention is explained in more detail below with reference to the drawings and an embodiment with reference to the figures.

Figur 1 zeigt eine Einschaltenergiespeichervorrichtung mit einem Federelement 1 als Einschaltenergiespeicher, der an einem ersten Ende 2 mittels einer Klinkenanordnung 3 mit einem Befestigungsteil 4 und an einem zweiten Ende 5 gelenkig mit einem Exzenter 6 verbunden ist . Der Exzenter 6 sowie eine Kurvenscheibe 7 sind fest an einer Spannwelle 8 angeordnet . Die Kurvenscheibe 7 wirkt mit einer Schaltwelle 9 zusammen, die Teil eines nicht dargestellten Betätigungsmechanismus für trennbare Schaltkontakte des Leistungsschalters ist. Durch das erste Ende 2 des Einschaltenergiespeichers 1 hindurchgeführt ist ein Führungsteil 10 mit einem Langloch 11 und einem Anschlagelement 12. Das Führungsteil 10 ist mit dem zweiten Ende 5 starr verbunden und mittels einer Achse 13, die sich durch das Langloch 11 erstreckt, am Befestigungsteil 4 gelagert. Die Klinkenanordnung 3 umfasst eine ebenfalls an der Achse 13 drehbar gelagerte Klinke 14 sowie eine Feder 15, die an ihrem ersten Ende 16 an der Klinke 14 und an ihrem zweiten Ende 17 am Befestigungsteil 4 befestigt ist. Die gestrichelt dargestellte Linie A entspricht der Bewegungsbahn des zweiten Endes 5 und die gestrichelt dargestellte Linie B der Bewegungsbahn des Anschlagelementes 12 bei einem Schalt- bzw. Spannvorgang des Einschaltenergiespeichers. Die Bewegungsbahn B zeichnet sich auf Grund der kinematischen Anordnung des Systems dadurch aus, das bei der Bewegung des Anschlagelementes 12 von einem oberen zu einem unteren Totpunkt des Einschaltenergiespeichers eine andere Bahnkurve überstrichen wird als in der ungekehrten Bewegung, wodurch die Verklinkung mit der Klinke 14 ermöglicht wird.1 shows a switch-on energy storage device with a spring element 1 as a switch-on energy storage, which is connected at a first end 2 by means of a latch assembly 3 with a mounting part 4 and at a second end 5 hinged to an eccentric 6. The eccentric 6 and a cam 7 are fixedly arranged on a clamping shaft 8. The cam 7 cooperates with a switching shaft 9, which is part of an actuating mechanism, not shown, for separable switching contacts of the circuit breaker. The guide member 10 is rigidly connected to the second end 5 and by means of an axis 13 which extends through the elongated hole 11, on the fastening part. 4 stored. The pawl assembly 3 comprises a likewise rotatably mounted on the axis 13 pawl 14 and a spring 15 which is fixed at its first end 16 to the pawl 14 and at its second end 17 on the fastening part 4. The dashed line A corresponds to the path of movement of the second end 5 and the dashed line B of the path of movement of the stop element 12 in a switching or clamping operation of the switch energy storage. The trajectory B is characterized on the basis of the kinematic arrangement of the system by the fact that during the movement of the stop element 12 from an upper to a lower dead center of the switch energy storage a different trajectory is swept over in the reverse direction, whereby the latching with the pawl 14 is made possible.
In Figur 1 befindet sich der Einschaltenergiespeicher in einem gespannten Zustand, wobei das Federelement unter Druck- Spannung ist. Das zweite Ende 5 ist am oberen Umkehrpunkt seiner Bewegungsbahnkurve A, das Anschlagelement 12 befindet sich nahe dem oberen Kniepunkt seiner Bahnkurve B, und die Achse 13 befindet sich am unteren Anschlag des Langlochs 11 des Führungsteils 10. Die Klinke 14 wird durch die Zugkraft der Feder 15 in einer ersten Position gehalten.In Figure 1, the switch-on energy storage is in a tensioned state, wherein the spring element is under pressure voltage. The second end 5 is at the upper reversal point of its trajectory curve A, the stop element 12 is located near the upper knee point of its trajectory B, and the axis 13 is located at the lower stop of the slot 11 of the guide member 10. The pawl 14 is by the tensile force of the spring 15 held in a first position.
Wird ein Schaltvorgang ausgelöst, so wird die im Einschalt- energiespeicher gespeicherte Energie über den Exzenter 6 und die Spannwelle 8 auf die Kurvenscheibe 7 und dadurch auf die Schaltwelle 9 übertragen. Dabei bewegt sich das zweite Ende 5 entlang der Linie A im Gegenuhrzeigersinn und das Anschlagelement 12 auf der Linie B im Uhrzeigersinn.If a switching operation is triggered, the energy stored in the switch-on energy store is transmitted via the eccentric 6 and the clamping shaft 8 to the cam 7 and thereby to the switching shaft 9. In this case, the second end 5 moves along the line A in the counterclockwise direction and the stop member 12 on the line B in the clockwise direction.
Figur 2 zeigt den Einschaltenergiespeicher 1 mit dem Klinken- mechanismus in einer Position kurz nach dem Auslösen eines Schaltvorganges, wobei sich der Einschaltenergiespeicher 1 teilweise entspannt hat. Die Energie des Einschaltenergiespeichers 1 führt zur Drehung der Kurvenscheibe über die Spannwelle 8 und damit zu einer Bewegung der Schalterwelle 9. Das zweite Ende 5 befindet sich in einer 9-Uhr-Position auf der Linie A, während sich das Anschlagelement 12 auf der Linie B nach unten bewegt hat. Die Achse 13 befindet sich relativ zum Langloch 11 aufgrund der Bewegung des mit dem zweiten Ende 5 verbundenen Führungsteils 10 in einer Position nahe am zweiten Ende des Langlochs 11.FIG. 2 shows the switch-on energy storage device 1 with the pawl mechanism in a position shortly after the triggering of a switching process, wherein the switch-on energy storage device 1 has partially relaxed. The energy of the turn-on energy storage 1 leads to the rotation of the cam on the tensioning shaft 8 and thus to a movement of the switch shaft 9. The second end 5 is in a 9 o'clock position on the line A, while the stop element 12 on the line B has moved down. The axis 13 is located relative to the slot 11 due to the movement of the second End 5 connected guide member 10 in a position close to the second end of the slot 11th
Figur 3 zeigt den Einschaltenergiespeicher in einem völlig entspannten Zustand, in dem das zweite Ende 5 und das Anschlagelement 12 die unteren Umkehrpunkte der jeweiligen Linien A und B erreicht haben. In dieser Position befindet sich die Achse 13 am oberen Ende des Langlochs. Das Anschlagelement 12 liegt an der Klinke 14 in einer L-förmigen Spannaus- sparung 18 an. In dieser Position beginnt das Anschlagelement 12, die drehbar gelagerte Klinke 14 gegen die Federkraft der Feder 15 vom Befestigungsteil 4 weg zu bewegen, wobei die Feder 15 gespannt wird.Figure 3 shows the switch-on energy storage in a fully relaxed state in which the second end 5 and the stopper 12 have reached the lower reversal points of the respective lines A and B. In this position, the axis 13 is located at the upper end of the slot. The stop element 12 bears against the pawl 14 in an L-shaped clamping recess 18. In this position, the stop member 12 begins to move the rotatably mounted pawl 14 against the spring force of the spring 15 from the fastening part 4 away, wherein the spring 15 is tensioned.
Figur 4 zeigt die Stellung des Einschaltenergiespeichers 1 und des Klinkenmechanismus direkt nach dem Schaltvorgang des Leistungsschalters. Die Kurvenscheibe 7 ist mit der Schalterwelle 9 nicht in Berührung, die Schaltwelle 9 und somit die Kontakte des Leistungsschalters sind in einer verriegelten und eingeschalteten Stellung. Durch die beim Schaltvorgang teilweise in Bewegungsenergie umgewandelte Energie des Einschaltenergiespeichers 1 drehen sich Kurvenscheibe 7 und Exzenter 6 über ihre Umkehrpunkte hinaus, wobei sich das Führungsteil 10 nach oben bewegt und das Anschlagelement 12 die Spannaussparung 18 der Klinke 14 verlässt . In diesem Moment wird die Klinke 14 durch die Zugkraft der Feder 15 in ihre erste Position zurückbewegt . Durch das Weiterdrehen des Exzenters 6 wird der Einschaltenergiespeicher 1 teilweise gespannt, wodurch der Einschaltenergiespeicher 1 eine Rücklauf- bewegung ausführt. Diese Rücklaufbewegung wird durch die von der Feder 15 in ihre erste Position zurückbewegte Klinke 14 begrenzt, wie mit Bezug auf die Figur 5 erläutert. Figur 5 zeigt die Stellung des Einschaltenergiespeichers 1 und des Klinkenmechanismus nach dem Schaltvorgang des Leistungsschalters mit eingerastetem Anschlagelement 12. Das Anschlagelement 12 greift in die Arretieraussparung 19 der Klinke ein und ist verriegelt. Durch diese Verriegelung wird ein weiteres Rücklaufen des Einschaltenergiespeichers 1 sicher verhindert. Damit kann sofort der Leistungsschalter sofort wieder ausgeschaltet werden und ein neuer Spannvorgang für den Einschaltenergiespeicher stattfinden. FIG. 4 shows the position of the switch-on energy store 1 and the latch mechanism directly after the switching operation of the circuit breaker. The cam 7 is not in contact with the switch shaft 9, the shift shaft 9 and thus the contacts of the circuit breaker are in a locked and on position. Due to the switching of the process partially converted into kinetic energy energy of the Einschaltergiespeichers 1 turn cam 7 and eccentric 6 beyond their turning points, with the guide member 10 moves upward and the stop member 12, the clamping recess 18 of the pawl 14 leaves. At this moment, the pawl 14 is moved back by the tensile force of the spring 15 in its first position. As a result of the further rotation of the eccentric 6, the switch-on energy store 1 is partially tensioned, as a result of which the switch-on energy store 1 carries out a return movement. This return movement is limited by the pawl 14 moved back by the spring 15 to its first position, as explained with reference to FIG. FIG. 5 shows the position of the switch-on energy store 1 and the latch mechanism after the switching operation of the circuit breaker with the stop element 12 engaged. The stop element 12 engages in the latching recess 19 of the latch and is locked. By this locking a further return of the switch-on energy storage 1 is reliably prevented. This can immediately switch off the circuit breaker immediately and take place a new clamping operation for the switch energy storage.
