Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung geht aus von einem Hybridleistungsschalter mit einem Getriebe gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a hybrid circuit breaker with a transmission according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Aus der Schrift EP 0 847 586 B1 ist ein Hybridleistungsschalter bekannt, der in einem elektrischen Hochspannungsnetz eingesetzt werden kann. Dieser Hybridleistungsschalter weist zwei in Reihe geschaltete Löschkammern auf, von denen eine erste mit SF6-Gas als Lösch- und Isoliermedium gefüllt ist, und eine zweite als Vakuumschaltkammer ausgebildet ist. Die zweite Löschkammer ist aussen von SF6-Gas umgeben. Die Hauptkontakte der beiden Löschkammern werden über ein einfaches Hebelgetriebe von einem gemeinsamen Antrieb simultan betätigt. Beide Löschkammern weisen eine Leistungsstrombahn, in welcher jeweils die abbrandfesten Hauptkontakte liegen, und parallel dazu eine Nennstrombahn auf, wobei diese Nennstrombahn nur eine einzige Unterbrechungsstelle aufweist. Beim Ausschalten wird stets zuerst die Nennstrombahn unterbrochen, worauf der abzuschaltende Strom auf die Leistungsstrombahn kommutiert. Die Leistungsstrombahn führt dann den Strom weiter bis zu dessen definitiver Abschaltung.From the Scriptures EP 0 847 586 B1 is a hybrid power switch is known, which can be used in a high voltage electrical network. This hybrid power switch has two series-connected extinguishing chambers, of which a first is filled with SF 6 gas as extinguishing and insulating medium, and a second is designed as a vacuum interrupter chamber. The second quenching chamber is surrounded outside by SF 6 gas. The main contacts of the two extinguishing chambers are actuated simultaneously by a common drive via a simple lever mechanism. Both extinguishing chambers have a power flow path, in which each of the erosion-resistant main contacts are, and in parallel to a nominal current path, said nominal current path having only a single point of interruption. When switching off, the nominal current path is always interrupted first, whereupon the current to be switched commutes to the power current path. The power current path then carries the power on until its definitive shutdown.

Derartige einfachen Hebelgetriebe lassen sich vergleichsweise schwer an die bei Hybridleistungsschaltern nötigen Bewegungsverläufe anpassen. Zudem werden die Lagerstellen mechanisch sehr hoch beansprucht, was eine aufwendige und teuere Gestaltung der Lagerstellen zur Folge hat, wodurch der Hybridleistungsschalter verteuert wird. Wird auf diese Gestaltung der Lagerstellen verzichtet, so wird durch den Zeitaufwand für die dann öfters nötigen Revisionen die Verfügbarkeit des Hybridleistungsschalters unvorteilhaft eingeschränkt. Zudem ist der Aufwand für die Montage des Hebelgetriebes im Inneren des Hybridleistungsschalters wegen der beschränkten Zugänglichkeit in diesem Bereich vergleichsweise gross.Such simple lever mechanism can be relatively difficult to adapt to the motion characteristics necessary for hybrid circuit breakers. In addition, the bearings are mechanically stressed very high, resulting in a complex and expensive design of the bearings result, making the hybrid circuit breaker is more expensive. If this design of the bearings is dispensed with, then the availability of the hybrid power switch is unfavorably restricted by the time required for the then frequently required revisions. In addition, the cost of mounting the lever mechanism inside the hybrid circuit breaker is relatively large because of the limited accessibility in this area.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Die Erfindung, wie sie in den unabhängigen Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen Hybridleistungsschalter mit einem Getriebe zu schaffen, welches im Inneren des Hybridleistungsschalters einfach zusammengefügt werden kann.The invention, as characterized in the independent claims, solves the problem of providing a hybrid circuit breaker with a transmission, which can be easily assembled inside the hybrid circuit breaker.

Der Hybridleistungsschalter weist mindestens zwei in Reihe geschaltete, von einem gemeinsamen Antrieb betätigte Löschkammern auf. Diesen Löschkammern ist ein gemeinsames Getriebe vorgeschaltet. Dieses Getriebe weist mindestens zwei Getriebeteile auf, welche zusammensteckbar ausgebildet sind, wobei das erste Getriebeteil mit der mindestens einen ersten Löschkammer und das zweite Getriebeteil mit der mindestens einen zweiten Löschkammer fest verbunden ist. Das Getriebe weist Mittel auf, die erlauben, die Bewegungen der mindestens zwei Löschkammern technisch sinnvoll aufeinander abzustimmen und bezüglich Zeitfolge und Schaltgeschwindigkeit derselben zu optimieren. Als besonders vorteilhaft erweist es sich, dass das Getriebe sowohl in der Einschaltstellung als auch in der Ausschaltstellung selbsthemmend ausgebildet ist, da damit zusätzliche Sperrvorrichtungen oder Verklinkungen nicht nötig sind. Zudem braucht der Antrieb in den beiden Endstellungen keine besonderen Haltekräfte aufzubringen, sodass hier ein einfacher und besonders kostengünstiger Antrieb eingesetzt werden kann. Das Getriebe ist vergleichsweise einfach montierbar, wodurch der Zeitbedarf für Montagearbeiten bei Revisionen vorteilhaft reduziert wird. Diese vereinfachte Montage benötigt einen vergleichsweise kleinen Zeitaufwand, sodass die betriebliche Verfügbarkeit des Hybridleistungsschalters vorteilhaft vergrössert wird.The hybrid power switch has at least two series-connected, operated by a common drive extinguishing chambers. These extinguishing chambers are preceded by a common gearbox. This transmission has at least two gear parts, which are designed to be plugged together, wherein the first gear part with the at least one first quenching chamber and the second gear part with the at least one second quenching chamber is firmly connected. The transmission has means that allow the movements of the at least two extinguishing chambers to coordinate technically meaningful and to optimize the timing and switching speed of the same. It proves to be particularly advantageous that the transmission is designed to be self-locking both in the closed position and in the switch-off position, since additional locking devices or latches are therefore unnecessary. In addition, the drive in the two end positions need not apply special holding forces, so that here a simple and very cost-effective drive can be used. The gearbox is relatively easy to install, whereby the time required for assembly work on revisions is advantageously reduced. This simplified assembly requires a relatively small amount of time, so that the operational availability of the hybrid circuit breaker is advantageously increased.

Die Längsachsen der beiden Löschkammern liegen bei einer bevorzugten Ausführungsform des Hybridleistungsschalters in einer Ebene und sind in einem Winkel α gegeneinander geneigt, wobei der Winkel α kleiner als 90° ausgebildet ist, vorzugsweise liegt er im Bereich zwischen 68° und 80°. Diese Anordnung der Löschkammern ermöglicht es, einen Hybridleistungsschalter zu erstellen, der eine vergleichsweise geringe Erstreckung in axialer Richtung aufweist, sodass der Platzbedarf für diesen Hybridleistungsschalter besonders klein ist.The longitudinal axes of the two extinguishing chambers are in a preferred embodiment of the hybrid circuit breaker in a plane and are inclined at an angle α against each other, wherein the angle α is less than 90 °, preferably in the range between 68 ° and 80 °. This arrangement of the extinguishing chambers makes it possible to create a hybrid circuit breaker having a comparatively small extent in the axial direction, so that the space required for this hybrid circuit breaker is particularly small.

Die weiteren Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The further embodiments of the invention are the subject of the dependent claims.

Die Erfindung, ihre Weiterbildung und die damit erzielbaren Vorteile werden nachstehend anhand der Zeichnung, welche lediglich einen möglichen Ausführungsweg darstellt, näher erläutert.The invention, its development and the advantages that can be achieved with it are explained in more detail below with reference to the drawing, which represents only one possible embodiment.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Die Figur 1 zeigt schematisch einen Schnitt durch eine erste Ausführungsform eines stark vereinfacht dargestellten Getriebes 29 im eingeschalteten Zustand eines Hybridleistungsschalters. Dieser Hybridleistungsschalter weist zwei nicht dargestellte in Reihe geschaltete Löschkammern auf, die hier beispielsweise gegeneinander abgewinkelt montiert sind. Die eine Löschkammer, beispielsweise eine mit Isoliergas gefüllte Löschkammer, ist entlang einer ersten Längsachse 1 erstreckt und konzentrisch zu dieser angeordnet, die andere Löschkammer, beispielsweise eine Vakuumschaltkammer, ist entlang einer zweiten Längsachse 2 erstreckt und konzentrisch zu dieser angeordnet. Hier schneiden sich die beiden Längsachsen unter einem Winkel α, wobei dieser Winkel α vorzugsweise im Bereich zwischen 68° und 80° liegt. Die beiden Längsachsen liegen in der Regel in einer Ebene, es ist jedoch durchaus möglich, diese Längsachsen in zwei parallel zueinander angeordneten Ebenen vorzusehen oder in zwei Ebenen, die sich unter einem konstruktiv sinnvollen Winkel schneiden.1 shows schematically a section through a first embodiment of a transmission 29 shown greatly simplified in the on state of a hybrid circuit breaker. This hybrid power switch has two, not shown, connected in series Extinguishing chambers, which are mounted here, for example, angled against each other. The one quenching chamber, for example a quenching chamber filled with insulating gas, extends along a first longitudinal axis 1 and is arranged concentrically therewith, the other quenching chamber, for example a vacuum interrupter chamber, extends along a second longitudinal axis 2 and is arranged concentrically therewith. Here, the two longitudinal axes intersect at an angle α, wherein this angle α is preferably in the range between 68 ° and 80 °. The two longitudinal axes are usually in one plane, but it is quite possible to provide these longitudinal axes in two mutually parallel planes or in two planes that intersect at a constructively meaningful angle.

Der Hybridleistungsschalter wird von einem nicht dargestellten, in der Regel auf Erdpotential liegenden Antrieb über ein Antriebsgestänge 3, welches zum Teil aus elektrisch isolierendem Material besteht, angetrieben. Das Antriebsgestänge 3 ist mittels eines Bolzens 4 mit einer in Richtung der ersten Längsachse 1 beweglichen, rohrförmig ausgebildeten Kontaktstange 5 verbunden. Die Kontaktstange 5 betätigt, je nach Bauart der mit Isoliergas gefüllten Löschkammer den oder die Kontakte derselben. Diese Löschkammer ist hier, wie bereits ausgeführt, nicht dargestellt. Die Kontaktstange 5 ist konzentrisch zu der ersten Längsachse 1 angeordnet und wird in einem feststehenden Gehäuse 6 in nicht dargestellten Führungsteilen axial gleitend geführt. Die Kontaktstange 5 weist einen Schlitz 7 auf, der parallel zur Zeichnungsebene verläuft. In diesem Schlitz 7 ist eine Rolle 8 auf einem mit der Kontaktstange 5 verbundenen Bolzen 9 drehbar gelagert, wobei die Drehachse 10 senkrecht zur ersten Längsachse 1 verläuft und diese in der Regel schneidet.The hybrid power switch is driven by a not shown, usually at ground potential drive via a drive linkage 3, which consists in part of electrically insulating material. The drive linkage 3 is connected by means of a bolt 4 with a movable in the direction of the first longitudinal axis 1, tubular contact rod 5. The contact rod 5 actuates, depending on the type of filled with insulating chamber extinguishing the one or the same contacts. This quenching chamber is here, as already stated, not shown. The contact rod 5 is arranged concentrically to the first longitudinal axis 1 and is axially slidably guided in a fixed housing 6 in guide parts, not shown. The contact rod 5 has a slot 7 which is parallel to the plane of the drawing. In this slot 7, a roller 8 is rotatably mounted on a connected to the contact rod 5 pin 9, wherein the axis of rotation 10 is perpendicular to the first longitudinal axis 1 and this intersects in the rule.

Die Rolle 8 ragt nach oben aus dem Schlitz 7 heraus und drückt hier eine ebene Oberfläche 11 einer drehbar gelagerten Kulissenscheibe 12 nach oben. In der gezeigten Einschaltstellung verläuft diese Oberfläche 11 parallel zur ersten Längsachse 1. Ein Bolzen 13 trägt die Kulissenscheibe 12. Der Bolzen 13 ist in einem mit dem Gehäuse 6 starr verbundenen Führungsgehäuse 14 gehalten. Das Führungsgehäuse 14 weist einen axialen Schlitz 15 auf, in welchem sich die Kulissenscheibe 12 bezogen auf die erste Längsachse 1 in radialer Richtung bewegen kann. Die Drehachse 16 der Kulissenscheibe 12 verläuft parallel zur Drehachse 10 der Rolle 8. Die als Gleitlager ausgebildeten Lagerstellen der Rolle 8 und der Kulissenscheibe 12 sind mit nicht dargestellten Isolierteilen versehen, welche verhindern, dass im Betrieb Streuströme durch diese Lagerstellen fliessen und sie beschädigen können. Das Führungsgehäuse 14 geht antriebsseitig in ein schematisch dargestelltes Isoliergehäuse 17 über. Das Gehäuse 6 geht antriebsseitig in ein schematisch dargestelltes Isoliergehäuse 18 über. Diese Isoliergehäuse 17 und 18 tragen die Aktivteile des Hybridleistungsschalters. Die die Aktivteile des Hybridleistungsschalters umgebenden Gehäuse, welche zugleich die Gasräume des Hybridleistungsschalters nach aussen hin abschliessen, sind hier nicht dargestellt.The roller 8 projects up out of the slot 7 and pushes a flat surface 11 of a rotatably mounted link plate 12 upwards. In the closed position shown, this surface 11 extends parallel to the first longitudinal axis 1. A bolt 13 carries the link plate 12. The bolt 13 is held in a guide housing 14 rigidly connected to the housing 6. The guide housing 14 has an axial slot 15, in which the link plate 12 can move relative to the first longitudinal axis 1 in the radial direction. The axis of rotation 16 of the link plate 12 extends parallel to the axis of rotation 10 of the roller 8. The slide bearings designed as bearings of the roller 8 and the crank plate 12 are provided with insulating parts, not shown, which prevent stray currents flow through these bearings in operation and can damage them. The guide housing 14 goes on the drive side in a schematically illustrated insulating housing 17 via. The housing 6 is on the drive side in a schematically illustrated insulating housing 18 via. These insulating housing 17 and 18 carry the active parts of the hybrid circuit breaker. The enclosing the active parts of the hybrid circuit breaker housing, which at the same time close off the gas chambers of the hybrid circuit breaker to the outside, are not shown here.

In der Kulissenscheibe 12 ist ein weiterer Bolzen 19 drehbar gelagert, an welchen ein Ende eines Doppelhebels 20 angelenkt ist, dessen anderes Ende mit einem Bolzen 21 drehbar verbunden ist. Der Bolzen 21 ist in einer den beweglichen Kontakt einer nicht dargestellten Vakuumschaltkammer betätigenden Kontaktstange 22 gehalten. Die Kontaktstange 22 erstreckt sich hier konzentrisch zur zweiten Längsachse 2. Mit dem Gehäuse 6 ist ein Flansch 23 fest verbunden, welcher die nicht dargestellte Vakuumschaltkammer trägt und die Kontaktstange 22 führt. In den Flansch 23 ist ein Anschlagteil 24 fest eingefügt, welches die Kontaktstange 22 konzentrisch umgibt. Die Kontaktstange 22 weist einen Bund 25 auf, auf den sich ein Tellerfedernpaket 26 abstützt. Das Tellerfedernpaket 26 wird zentral durch einen zylindrisch ausgebildeten Absatz 27 der Kontaktstange 22 geführt. Auf der dem Bund 25 entgegengesetzten Seite stützt sich das Tellerfedernpaket 26 gegen eine erste Schulter 24a des Anschlagteils 24 ab. Das Tellerfedernpaket 26 ist hier in der Einschaltstellung vorgespannt und stellt sicher, dass die Kontakte der eingeschalteten Vakuumschaltkammer stets mit der nötigen Kontaktkraft gegeneinander gedrückt werden.In the link plate 12, a further pin 19 is rotatably mounted, to which one end of a double lever 20 is articulated, the other end is rotatably connected to a pin 21. The bolt 21 is held in a movable contact of a vacuum interrupter chamber not shown actuating contact rod 22. The contact rod 22 extends concentrically to the second longitudinal axis 2. With the housing 6, a flange 23 is fixedly connected, which carries the vacuum interrupter chamber, not shown, and the contact rod 22 leads. In the flange 23, a stop member 24 is fixed inserted, which surrounds the contact rod 22 concentrically. The contact rod 22 has a collar 25 on which a cup spring package 26 is supported. The cup spring package 26 is guided centrally by a cylindrically shaped shoulder 27 of the contact rod 22. On the collar 25 opposite side, the cup spring assembly 26 is supported against a first shoulder 24a of the stop member 24 from. The disc spring assembly 26 is biased here in the closed position and ensures that the contacts of the switched vacuum interrupter chamber are always pressed with the necessary contact force against each other.

Ein erster Pfeil 28 deutet an, in welche Richtung, hier nach rechts, der nicht dargestellte Antrieb das Antriebsgestänge 3 und über dieses die Kontaktstange 5, welche die Einschaltbewegung der mit Isoliergas gefüllten Löschkammer bewirkt, bewegt hat. Das Getriebe 29 setzt diese axiale Bewegung der Kontaktstange 5 um in eine Bewegung der Kontaktstange 22 in eine Richtung, die durch einen zweiten Pfeil 30 angedeutet wird, hier ist dies schräg nach oben in Richtung der zweiten Längsachse 2. Im Getriebe 29 wirken folgende Teile zusammen: die Kontaktstange 5 mit der eingelagerten Rolle 8, die Kulissenscheibe 12, die Bolzen 13 und 19, der Doppelhebel 20, der Bolzen 21 und die Kontaktstange 22, betätigt wird das Getriebe 29 durch das Antriebsgestänge 3. Das Getriebe 29 verknüpft die Bewegungen der beiden Löschkammern miteinander und stimmt die Bewegungsabläufe technisch sinnvoll aufeinander ab. Das Getriebe 29 ist so ausgelegt, dass es in der Einschaltstellung selbsthemmend wirkt, d. h. der Hybridleistungsschalter wird auch bei Erschütterungen ohne zusätzliche Verriegelung und ohne vom Antrieb aufzubringende Kraft in dieser Stellung gehalten.A first arrow 28 indicates in which direction, here to the right, the drive, not shown, has moved the drive linkage 3 and via this the contact rod 5, which causes the switch-on movement of the extinguishing chamber filled with insulating gas. The gear 29 sets this axial movement of the contact rod 5 in a movement of the contact rod 22 in a direction which is indicated by a second arrow 30, here this is obliquely upward in the direction of the second longitudinal axis 2. In the transmission 29, the following parts act together : the contact rod 5 with the embedded roller 8, the crank plate 12, the bolts 13 and 19, the double lever 20, the pin 21 and the contact rod 22, the transmission 29 is actuated by the drive linkage 3. The transmission 29 links the movements of the two Fire extinguishers with each other and agrees the motion sequences technically meaningful. The gear 29 is designed so that it acts self-locking in the closed position, ie the hybrid circuit breaker is held in this position even with shock without additional locking and without applied by the drive force.

Die Figur 2 zeigt einen schematisch dargestellten Schnitt durch die erste Ausführungsform des stark vereinfacht dargestellten Getriebes 29 im ausgeschalteten Zustand des Hybridleistungsschalters. Ein Pfeil 31 gibt die Richtung der Ausschaltbewegung an, hier nach links, in die der nicht dargestellte Antrieb das Antriebsgestänge 3 und über dieses die Kontaktstange 5, welche die Ausschaltbewegung der mit Isoliergas gefüllten Löschkammer bewirkt, bewegt hat. Das Getriebe 29 setzt diese axiale Bewegung der Kontaktstange 5 um in eine Bewegung der Kontaktstange 22 in eine Richtung, die durch einen zweiten Pfeil 32 angedeutet wird, hier ist dies schräg nach unten in Richtung der zweiten Längsachse 2. Die Ausschaltbewegung wird beendet, wenn der Bund 25 der Kontaktstange 22 auf die Schulter 24b des Anschlagteils 24 auftrifft, das Tellerfedernpaket 26 ist dann nahezu entspannt.FIG. 2 shows a schematically represented section through the first embodiment of the transmission 29 shown in greatly simplified form in the switched-off state of the hybrid circuit breaker. An arrow 31 indicates the direction of the switch-off, here to the left, in which the drive, not shown, the drive linkage 3 and via this the contact rod 5, which causes the switch-off movement of the filled with insulating gas quenching chamber has moved. The gear 29 sets this axial movement of the contact rod 5 in a movement of the contact rod 22 in a direction which is indicated by a second arrow 32, here this is obliquely downward in the direction of the second longitudinal axis 2. The turn-off is terminated when the Bund 25 of the contact rod 22 impinges on the shoulder 24b of the stop member 24, the cup spring assembly 26 is then almost relaxed.

Am Anfang der Ausschaltbewegung bewegt sich die Rolle 8 entlang der ebenen Oberfläche 11 der Kulissenscheibe 12, wobei das vorgespannte Tellerfedernpaket 26 die Kulissenscheibe 12 gegen die Rolle 8 drückt. An die ebene Oberfläche 11 schliesst sich tangential eine gekrümmte Fläche 33 mit einem Krümmungsradius R an. Der Krümmungsradius R ist geringfügig grösser als der Radius der Rolle 8, sodass sich die Rolle 8, wenn sie diesen Bereich erreicht, nicht verklemmen kann. Sobald die Rolle 8 die gekrümmte Fläche 33 erreicht, drückt sie mit der Kraft des Antriebs gegen diese gekrümmte Fläche 33 und die Kulissenscheibe 12 beginnt sich im Uhrzeigersinn um die Drehachse 16 zu drehen, diese Drehbewegung wird unterstützt durch die im Tellerfedernpaket 26 gespeicherte Energie. Die Drehbewegung der Kulissenscheibe 12 ist auf den vorgegebenen Hub der Vakuumschaltkammer abgestimmt. Unmittelbar vor dem Erreichen der Ausschaltstellung der Vakuumschaltkammer geht die gekrümmte Fläche 33 der Kulissenscheibe 12 über in eine tangential zur Rolle 8 verlaufende ebene Fläche 34. Die Rolle 8 hält beim Erreichen der Ausschaltstellung die Vakuumschaltkammer mittels der Kulissenscheibe 12 und der mit ihr verbundenen weiteren Elemente in ihrer geöffneten Position. Das Getriebe 29 ist so ausgelegt, dass es auch in der Ausschaltstellung selbsthemmend wirkt, d. h. der Hybridleistungsschalter wird auch bei Erschütterungen ohne zusätzliche Verriegelung und ohne vom Antrieb aufzubringende Kraft in dieser Stellung gehalten.At the beginning of the opening movement, the roller 8 moves along the flat surface 11 of the crank plate 12, wherein the prestressed disc spring package 26 presses the link plate 12 against the roller 8. A curved surface 33 with a radius of curvature R adjoins the planar surface 11 tangentially. The radius of curvature R is slightly greater than the radius of the roller 8, so that the roller 8, when it reaches this area, can not jam. Once the roller 8 reaches the curved surface 33, it presses with the force of the drive against this curved surface 33 and the crank plate 12 begins to rotate in a clockwise direction about the axis of rotation 16, this rotation is supported by the energy stored in the disc spring 26 energy. The rotational movement of the crank plate 12 is tuned to the predetermined stroke of the vacuum interrupter chamber. Immediately before reaching the switch-off position of the vacuum interrupter chamber, the curved surface 33 of the link plate 12 passes over into a tangential to the roller 8 extending flat surface 34. The roller 8 stops on reaching the switch-off the vacuum interrupter chamber by means of the crank plate 12 and the other elements connected to it in its open position. The gear 29 is designed so that it acts self-locking even in the off position, ie the hybrid circuit breaker is held in this position, even with shock without additional locking and without applied by the drive force.

Mittels der äusseren Form der Kulissenscheibe 12 wird der Bewegungsablauf der Vakuumschaltkammer optimal an den der mit Isoliergas gefüllten Löschkammer angepasst. Zudem wird durch diese Kulissenscheibe 12 der zeitliche Ablauf der Bewegung der Vakuumschaltkammer bezogen auf die Bewegung der mit Isoliergas gefüllten Löschkammer gesteuert, so können beispielsweise zeitliche Modifikationen im Bewegungsablauf sehr einfach durch Versetzen der Rolle 8 in Richtung der ersten Längsachse 1 erzielt werden.By means of the outer shape of the crank disk 12, the movement of the vacuum interrupter chamber is optimally adapted to the extinguishing chamber filled with insulating gas. In addition, the timing of the movement of the vacuum interrupter chamber is controlled by the slide disc 12 relative to the movement of the filled with insulating chamber, for example, temporal modifications in the movement can be achieved very easily by moving the roller 8 in the direction of the first longitudinal axis 1.

Die Figur 3 zeigt einen Schnitt durch eine zweite Ausführungsform eines stark vereinfacht und schematisch dargestellten Getriebes 29 im eingeschalteten Zustand des Hybridleistungsschalters. Die mit Isoliergas gefüllte Löschkammer, ist entlang einer ersten Längsachse 1 erstreckt und konzentrisch zu dieser angeordnet, die andere Löschkammer, beispielsweise eine Vakuumschaltkammer, ist entlang einer zweiten Längsachse 2 erstreckt und konzentrisch zu dieser angeordnet. Hier schneiden sich die beiden Längsachsen unter einem Winkel α. Die beiden Längsachsen liegen in der Regel in einer Ebene, es ist jedoch durchaus möglich, diese Längsachsen in zwei parallel zueinander angeordneten Ebenen vorzusehen oder in zwei Ebenen, die sich unter einem konstruktiv sinnvollen Winkel schneiden. Die mit Isoliergas gefüllte Löschkammer wird durch eine Kontaktstange 5 betätigt. Von den übrigen Aktivteilen dieser Löschkammer ist hier lediglich noch ein metallisches Führungsrohr 35 gezeigt, welches nach oben hin einen axial erstreckten Schlitz 36 aufweist, und welches mit der Löschkammer starr verbunden ist. In diesem Führungsrohr 35 ist ein Bund 37 der Kontaktstange 5 gleitend geführt.3 shows a section through a second embodiment of a greatly simplified and schematically illustrated transmission 29 in the on state of the hybrid circuit breaker. The quenching chamber filled with insulating gas is along a first longitudinal axis 1 extends and arranged concentrically to this, the other quenching chamber, for example, a vacuum switching chamber is along a second longitudinal axis 2 extends and arranged concentrically to this. Here, the two longitudinal axes intersect at an angle α. The two longitudinal axes are usually in one plane, but it is quite possible to provide these longitudinal axes in two mutually parallel planes or in two planes that intersect at a constructively meaningful angle. The quenching chamber filled with insulating gas is actuated by a contact rod 5. Of the remaining active parts of this quenching chamber, only a metallic guide tube 35 is shown here, which is upwards has an axially extending slot 36, and which is rigidly connected to the quenching chamber. In this guide tube 35, a collar 37 of the contact rod 5 is slidably guided.

Antriebsseitig ist an diesen Bund 37 ein zylindrisch ausgebildetes Kulissenteil 38 angefügt, welches nach oben hin im Bereich des Schlitzes 36 ebenfalls einen axial erstreckten Schlitz 39 aufweist. Das Kulissenteil 38 ist sowohl an der Vorderseite als auch an der Rückseite mit einem deckungsgleich ausgebildeten Führungsschlitz 40 versehen. In den beiden Führungsschlitzen 40 wird ein zylindrisch ausgebildeter Bolzen 41 geführt, der in der Mitte zwischen den beiden Führungsschlitzen 40 die Kontaktstange 22 trägt, welche die Vakuumschaltkammer betätigt. Die Kontaktstange 22 ist im Bereich der Schlitze 36 und 39 abgeflacht, sodass diese Schlitze 36 und 39 vergleichsweise schmal ausgeführt werden können, sodass sie die Tragfähigkeit des Führungsrohrs 35 und des Kulissenteils 38 nur unwesentlich schwächen. Die Achse des Bolzens 41 liegt senkrecht zur Zeichnungsebene, der Bolzen 41 kann sich beim Schalten entlang einer gestrichelten Wirkungslinie 42, welche zugleich die Mittellinie der Führungsschlitze 40 ist, bewegen. Die gestrichelte Wirkungslinie 42 verläuft zunächst parallel zur ersten Längsachse 1, ein Abschnitt 42a der gestrichelten Wirkungslinie 42 neigt sich dann unter einem Winkel β der ersten Längsachse 1 zu und geht dann wieder in einen parallel zur ersten Längsachse 1 verlaufenden Abschnitt 42b über. Je grösser der Winkel β ausgebildet ist, desto höher ist die Ausschaltgeschwindigkeit und auch die Einschaltgeschwindigkeit der Vakuumschaltkammer. Wird der Übergang der gestrichelten Wirkungslinie 42 vom parallelen zum geneigten Abschnitt 42a axial verschoben, so können die Schaltzeitpunkte der beiden Löschkammern aufeinander abgestimmt werden.On the drive side, a cylindrically designed slide part 38 is attached to this collar 37, which also has an axially extending slot 39 in the region of the slot 36 at the top. The guide member 38 is provided both on the front and on the back with a congruent guide slot 40. In the two guide slots 40, a cylindrically shaped bolt 41 is guided, which carries in the middle between the two guide slots 40, the contact rod 22 which actuates the vacuum interrupter chamber. The contact rod 22 is flattened in the region of the slots 36 and 39, so that these slots 36 and 39 can be made comparatively narrow, so that they weaken the carrying capacity of the guide tube 35 and the guide member 38 only insignificantly. The axis of the bolt 41 is perpendicular to the plane of the drawing, the bolt 41 can move when switching along a dashed line of action 42, which is also the center line of the guide slots 40. The dashed line of action 42 initially runs parallel to the first longitudinal axis 1, a section 42a of the dashed line of action 42 then inclines toward the first longitudinal axis 1 at an angle β and then merges again into a section 42b running parallel to the first longitudinal axis 1. The greater the angle β is formed, the higher the turn-off speed and also the turn-on speed of the vacuum interrupter chamber. If the transition of the dashed line of action 42 is displaced axially from the parallel to the inclined portion 42a, the switching times of the two extinguishing chambers can be coordinated.

Antriebsseitig sind die beiden Führungsschlitze 40 offen, sodass bei der Montage des Getriebes 29 der Bolzen 41 von dieser Seite in die beiden Führungsschlitze 40 des Kulissenteils 38 eingeführt werden kann. Es ist auch möglich, die Führungsschlitze 40 antriebsseitig etwas trichterförmig zu erweitern, um das Einführen des Bolzens 41 zu erleichtern. Nach dem Einführen des Bolzens 41 wird von der Antriebsseite her das Antriebsgestänge 3 eingeführt, an dessen dem Kulissenteil 38 zugewandten Ende der Bolzen 4 und seine Halterung 43 drehbar gelagert sind. Die Halterung 43 wird durch das Kulissenteil 38 zentriert und durch eine mit dem Kulissenteil 38 verschraubte Überwurfmutter 44 kraftschlüssig gegen dieses gedrückt und so in Position gehalten. Die Überwurfmutter 44 wird von der Antriebsseite her festgezogen und gesichert. Die Montage des Getriebes 29 ist auf diese Art sehr einfach möglich. Im Innern des Getriebes 29 sind keine aufwendigen Montage- und Justierarbeiten nötig, was eine vorteilhaft rasche Montage erlaubt.On the drive side, the two guide slots 40 are open, so that in the assembly of the transmission 29, the bolt 41 can be inserted from this side into the two guide slots 40 of the guide member 38. It is also possible to expand the guide slots 40 on the drive side somewhat funnel-shaped in order to facilitate the insertion of the bolt 41. After insertion of the bolt 41, the drive linkage 3 is introduced from the drive side, at the end of the link member 38 facing the bolt 4 and its holder 43 are rotatably mounted. The holder 43 is centered by the slide member 38 and pressed by a bolted to the slide member 38 union nut 44 frictionally against this and held in position. The union nut 44 is tightened and secured from the drive side. The assembly of the transmission 29 is very easily possible in this way. In the interior of the transmission 29 no complex assembly and adjustment are necessary, which allows an advantageous rapid assembly.

Diese zweite Ausführungsform des Getriebes 29 ist ebenfalls sowohl in der Einschaltstellung als auch in der Ausschaltstellung selbsthemmend. Es sind keine aufwendigen zusätzlichen Verriegelungen oder vom Antrieb aufzubringende zusätzliche Haltekräfte nötig, was den Hybridleistungsschalter vorteilhaft verbilligt.This second embodiment of the transmission 29 is also self-locking both in the closed position and in the open position. There are no costly additional locks or applied by the drive additional holding forces necessary, which advantageously reduces the cost of the hybrid circuit breaker.

Die Figur 4 zeigt einen schematisch dargestellten Schnitt durch die zweite Ausführungsform des stark vereinfacht dargestellten Getriebes 29 im ausgeschalteten Zustand des Hybridleistungsschalters. Der Pfeil 31 gibt die Richtung der Ausschaltbewegung an, hier nach links, in die der nicht dargestellte Antrieb das Antriebsgestänge 3 und über dieses die Kontaktstange 5, welche die Ausschaltbewegung der mit Isoliergas gefüllten Löschkammer bewirkt, bewegt hat. Das Getriebe 29 setzt diese axiale Bewegung der Kontaktstange 5 um in eine Bewegung der Kontaktstange 22 in eine Richtung, die durch einen zweiten Pfeil 32 angedeutet wird, hier ist dies schräg nach unten in Richtung der zweiten Längsachse 2. Am Beginn der Ausschaltbewegung gleitet der Bolzen 41 entlang der gestrichelten Wirkungslinien 42 nach rechts. Da die gestrichelten Wirkungslinien 42 zunächst parallel zur ersten Längsachse 1 verlaufen, kann der Druck des vorgespannten Tellerfedernpakets 26 zunächst keine Bewegung der Kontaktstange 22 in Richtung des Pfeils 32 bewirken. Sobald der Bolzen 41 den geneigten Abschnitt 42a erreicht, beginnt die Bewegung der Vakuumschaltkammer in Ausschaltrichtung. Die Ausschaltbewegung der Vakuumschaltkammer ist beendet, wenn der Bund 25 der Kontaktstange 22 auf die Schulter 24b des Anschlagteils 24 auftrifft, das Tellerfedernpaket 26 ist dann nahezu entspannt. Der Bolzen 41 hat dann den Abschnitt 42b der gestrichelten Wirkungslinie 42 erreicht. Die Vakuumschaltkammer wird dann durch die Kontaktstange 22 in der Ausschaltstellung gehalten.FIG. 4 shows a schematically represented section through the second embodiment of the transmission 29 shown in greatly simplified form in the switched-off state of the hybrid circuit breaker. The arrow 31 indicates the direction of the switch-off, here to the left, in which the drive, not shown, the drive linkage 3 and via this the contact rod 5, which causes the switch-off movement of the filled with insulating gas quenching chamber has moved. The gear 29 converts this axial movement of the contact rod 5 in a movement of the contact rod 22 in a direction which is indicated by a second arrow 32, here this is obliquely downward in the direction of the second longitudinal axis 2. At the beginning of the opening movement of the bolt 41 slides along the dashed lines of action 42 to the right. Since the dashed lines of action 42 initially extend parallel to the first longitudinal axis 1, the pressure of the prestressed disc spring packet 26 can initially cause no movement of the contact rod 22 in the direction of the arrow 32. As soon as the bolt 41 reaches the inclined portion 42a, the movement of the vacuum interrupter chamber in the disconnection direction begins. The opening movement of the vacuum interrupter chamber is completed when the collar 25 of the contact rod 22 impinges on the shoulder 24b of the stop member 24, the disc spring assembly 26 is then almost relaxed. The bolt 41 has then reached the portion 42b of the dashed line of action 42. The vacuum interrupter chamber is then held by the contact rod 22 in the off position.

Durch das einfach montierbare Getriebe 29 wird der Zeitbedarf für Montagearbeiten bei Revisionen vorteilhaft reduziert, die Montage wird stark vereinfacht und die betriebliche Verfügbarkeit des Hybridleistungsschalters wird vorteilhaft vergrössert. Die beiden gezeigten Ausführungsformen des Getriebes 29 sind sowohl in der Einschaltstellung als auch in der Ausschaltstellung selbsthemmend. Es sind demnach keine aufwendigen zusätzlichen Verriegelungen oder vom Antrieb aufzubringende zusätzliche Haltekräfte nötig, was den Hybridleistungsschalter vorteilhaft verbilligt.Due to the easily mountable gear 29, the time required for assembly work on revisions is advantageously reduced, the assembly is greatly simplified and the operational availability of the hybrid circuit breaker is advantageously increased. The two embodiments of the transmission 29 shown are self-locking both in the closed position and in the open position. There are therefore no costly additional locks or applied by the drive additional holding forces necessary, which advantageously reduces the cost of the hybrid circuit breaker.
