Description

Die Erfindung bezieht sich auf einen Hochspannungsleistungsschalter mit einem Kontaktsystem, mit einem durch einen Schalterantrieb antreibbaren Kontaktstück und mit einem dem Kontaktstück gegenüberstehenden, mittels Übertragungselementen antreibbaren Gegenkontaktstück, bei dem durch einige Übertragungselemente ein Hilfsgetriebe gebildet ist und bei dem das Kontaktstück mit einem ersten elektrischen Anschluß des Hochspannungsleistungsschalters und das Gegenkontaktstück mit einem zweiten elektrischen Anschluß des Hochspannungsleistungsschalters über einen Strompfad elektrisch leitend verbunden ist.The invention relates to a high-voltage circuit breaker with a contact system, with one through one Switch drive driven contact piece and with a Opposing contact piece, by means of transmission elements drivable mating contact piece, by some Transmission elements an auxiliary gear is formed and at which the contact piece with a first electrical connection of the high-voltage circuit breaker and the counter contact piece with a second electrical connection of the high-voltage circuit breaker electrically conductive via a current path connected is.

Ein derartiger Hochspannungsleistungsschalter ist beispielsweise aus der europäischen Patentschrift 0 313 813 B1 bekannt. Dort ist ein Kontaktstück mittels eines Schalterantriebs antreibbar, wobei insbesondere beim Ausschaltvorgang ein stiftförmiges Gegenkontaktstück zur Erhöhung der Kontakttrennungsgeschwindigkeit ebenfalls antreibbar ist. Dabei wird die Bewegung von dem angetriebenen Kontaktstück über Bewegungsübertragungselemente bzw. ein Hilfsgetriebe auf das Gegenkontaktstück übertragen, um dies in einer zur Bewegungsrichtung des Kontaktstückes entgegengesetzten Richtung anzutreiben.Such a high voltage circuit breaker is for example known from European patent specification 0 313 813 B1. There is a contact piece by means of a switch drive drivable, especially during the switch-off process a pin-shaped counter contact piece to increase the contact separation speed is also drivable. there the movement of the driven contact piece via movement transmission elements or an auxiliary gear on the Mating contact piece transferred to this in a direction of movement to drive the contact piece in the opposite direction.

Aus der FR 2 491 675 geht ebenfalls ein Hochspannungsleistungsschalter hervor, bei dem ein antreibbares Kontaktstück und ein gegensinnig zu diesem mittels eines Hilfsgetriebes und Bewegungsübertragungselementen antreibbares Gegenkontaktstück vorgesehen ist. A high-voltage circuit breaker also emerges from FR 2 491 675 in which a drivable contact piece and an opposite to this by means of an auxiliary transmission and movement transmission elements drivable mating contact piece is provided.

Aus der EP 0 025 833 A1 ist ebenfalls ein Hochspannungsleistungsschalter bekannt, bei dem ein Kontaktstück und ein Gegenkontaktstück mittels eines Getriebes miteinander gekoppelt und gegensinnig im Ausschaltfall antreibbar sind.A high-voltage circuit breaker is also known from EP 0 025 833 A1 known in which a contact piece and a Counter contact piece coupled together by means of a gear and can be driven in opposite directions when switched off.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Hochspannungsleistungsschalter der eingangs genannten Art zu schaffen, dessen Lebensdauer gegenüber den bekannten Schaltern verlängert ist.The present invention has for its object a High-voltage circuit breakers of the type mentioned at the beginning create its lifespan compared to the known switches is extended.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein zu dem Strompfad elektrisch paralleler Parallelstrompfad, der von dem Gegenkontaktstück über die Übertragungs-elemente zu dem zweiten Anschluß des Hochspannungsleistungsschalters führt, durch eine Isolierstelle unterbrochen ist. Gemäß dem Patentanspruch 2 wird die Aufgabe dadurch gelöst, daß wenigstens eines der Übertragungselemente zur Unterbrechung eines zu dem Strompfad parallelen Parallelstrompfades zwischen dem Gegenkontaktstück und dem zweiten Anschluß des Hochspannungsleistungsschalters elektrisch isolierend ausgebildet ist.The object is achieved in that a the current path electrically parallel parallel current path, the from the mating contact piece to the transmission elements the second connection of the high-voltage circuit breaker leads, is interrupted by an isolation point. According to the Claim 2 the object is achieved in that at least one of the transmission elements to interrupt a parallel current path parallel to the current path between the Mating contact piece and the second connection of the high-voltage circuit breaker electrically insulated is.

Die Hochspannungsleistungsschalter aus dem Stand der Technik haben die Eigenschaft gemeinsam, daß das Gegenkontaktstück mittels eines Hilfsgetriebes und Übertragungselementen angetrieben wird, die wenigstens teilweise mit ortsfesten Teilen des Schalters, beispielsweise zu Lagerungszwecken, verbunden sind. Beispielsweise müssen Zahnräder oder Hebel schwenkbar ortsfest gelagert werden.The state-of-the-art high-voltage circuit breakers have the property in common that the mating contact piece driven by an auxiliary transmission and transmission elements will, at least partially with stationary parts of the switch, for example for storage purposes are. For example, gears or levers must be pivoted be stored stationary.

Hierbei wurde das Problem nicht beachtet, daß hiermit von dem Gegenkontaktstück zum zweiten Anschluß des Leistungsschalters über das Hilfsgetriebe bzw. Bewegungsübertragungselemente ein Parallelstrompfad geschaffen wird, der parallel zum Hauptstrompfad liegt, welcher von dem Gegenkontaktstück meistens über Gleitkontakte zu dem zweiten Anschluß führt.Here, the problem was ignored, that hereby by the Mating contact piece for the second connection of the circuit breaker via the auxiliary transmission or motion transmission elements Parallel current path is created that is parallel to Main current path, which is from the mating contact piece mostly leads to the second connection via sliding contacts.

Da die Bewegungsübertragungselemente bzw. das Hilfsgetriebe im Normalfall nicht zur Führung hoher Ströme, wie sie beispielsweise im Kurzschlußfall auftreten, ausgelegt sind, wird nach einigen Schaltspielen durch eine derartige elektrische Belastung der Antriebsmechanismus für das Gegenkontaktstück zerstört oder wenigstens beschädigt.Because the motion transmission elements or the auxiliary transmission normally not to carry high currents, such as those occur in the event of a short circuit, are designed after a few operations by such an electrical Load the drive mechanism for the counter contact piece destroyed or at least damaged.

Durch die erfindungsgemäße Lösung wird ein Stromfluß außerhalb des Hauptstrompfades vollständig verhindert, so daß keine Beschädigungen von mechanischen Teilen durch einen solchen Stromfluß möglich sind.The solution according to the invention prevents current from flowing of the main current path completely prevented, so that no damage to mechanical parts Current flow are possible.

Außerdem werden auch magnetische Kraftwirkungen verhindert, die durch parallele, stromdurchflossene Strompfade entstehen und die beispielsweise den Kontaktdruck bei Gleitkontakten durch Abheben von Kontaktfingern negativ beeinflussen können.Magnetic force effects are also prevented, that result from parallel current paths through which current flows and for example the contact pressure for sliding contacts can have a negative impact by lifting contact fingers.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß das dem Kontaktstück abgewandte Ende des Gegenkontaktstückes, in dem Bereich, in dem der Angriffspunkt der Übertragungselemente liegt, aus einem Isolierstoff besteht.An advantageous embodiment of the invention provides that the end of the counter-contact piece facing away from the contact piece, in the area where the point of attack of the transmission elements is made of an insulating material.

Hierdurch ist der Nebenstrompfad vom Gegenkontaktstück über das Hilfsgetriebe zum zweiten Anschluß des Leistungsschalters bereits am Angriffspunkt der Übertragungselemente an dem Gegenkontaktstück unterbrochen.As a result, the bypass path from the mating contact piece is over the auxiliary gear for the second connection of the circuit breaker already at the point of attack of the transmission elements on the Mating contact piece interrupted.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß wenigstens ein Lager oder eine Welle des Hilfsgetriebes wenigstens teilweise aus einem Isolierstoff besteht. A further advantageous embodiment of the invention provides before that at least one bearing or shaft of the auxiliary transmission consists at least partially of an insulating material.

Weitere vorteilhafte Ausgestaltungen der Erfindungen sehen vor, daß ein in einer Gleitführung gleitender Stift des Hilfsgetriebes wenigstens teilweise aus Isolierstoff besteht oder daß eine Gleitführung des Hilfsgetriebes aus einem Isolierstoff besteht.See further advantageous embodiments of the inventions before that a sliding in a sliding guide pin Auxiliary gear consists at least partially of insulating material or that a sliding guide of the auxiliary gear from an insulating material consists.

Figur 1 zeigt in Anlehnung an Figur 2 der EP 0 313 813 B1 ausschnittsweise den feststehenden Dauerstromkontakt 5 eines Hochspannungsleistungsschalters, in den von links das axial antreibbare Dauerstromkontaktstück 4 mit der daran befestigten Isolierdüse 8 und dem axial antreibbaren Kontaktstück 9 hineinragt. Dabei zeigt die Figur in der unteren Hälfte die Einschaltstellung des antreibbaren Dauerstromkontaktstückes 4 und in der oberen Hälfte die Position der Isolierdüse 8 in der Ausschaltstellung. - In der Einschaltstellung umgibt die Isolierdüse 8 auch das entgegengesetzt angetriebene Gegenkontaktstück 7. In dieser Schaltstellung sind der erste Anschluß 39 und der zweite Anschluß 40 des Schalters miteinander leitend verbunden. Die Anschlüsse (39,40) sind in der Figur 1 symbolisch dargestellt. An der Isolierdüse 8 ist das stangenartige Übertragungselement 27 befestigt, das hier nicht als Zahnstange sondern als Koppelstange ausgebildet ist und zum Antrieb eines Hilfsgetriebes einen Zapfen 28 aufweist, der quer zur Schubrichtung der mit einem U-förmigen Querschnitt versehenen Koppelstange 27 angeordnet ist. Die Koppelstange kann auch einen L- oder T-förmigen Querschnitt aufweisen, wobei jeweils ein Querschnittsteil eine Gleitbahn zur Führung der Koppelstange bildet. Beim Ausführungsbeispiel bildet der Boden 34 des U-förmigen Querschnittes die Gleitbahn.Figure 1 shows on the basis of Figure 2 of EP 0 313 813 B1 sections of the fixed continuous current contact 5 a High-voltage circuit breaker, in the axially from the left drivable continuous current contact piece 4 with the attached Insulating nozzle 8 and the axially driven contact piece 9 protrudes. The figure shows the in the lower half Switch-on position of the drivable continuous current contact piece 4 and in the top half the position of the isolation nozzle 8 in the off position. - In the on position surrounds the Isolierdüse 8 also the counter-driven counter-contact piece 7. The first connection is in this switch position 39 and the second terminal 40 of the switch with each other conductively connected. The connections (39.40) are in the Figure 1 represented symbolically. At the insulating nozzle 8 that is rod-like transmission element 27 attached here is not designed as a rack but as a coupling rod and has a pin 28 for driving an auxiliary transmission, the transverse to the direction of thrust with a U-shaped Cross-section provided coupling rod 27 is arranged. The Coupling rod can also have an L- or T-shaped cross section have, each having a cross-sectional part of a slideway forms for guiding the coupling rod. In the embodiment the bottom 34 of the U-shaped cross section forms the slideway.

Abweichend von der bekannten Konstruktion ist gemäß Figur 2 die Koppelstange 27 in zwei Lagerwangen 31 geführt, die Teil eines Gehäuses 30 sind. Dieses Gehäuse ist an einer Kontaktbrücke 32 befestigt, welche an dem feststehenden Dauerstromkontaktstück 5 befestigt ist und das feststehende Teil 33 eines rohrförmigen Gleitkontaktes trägt, in dem das entgegengesetzt antreibbare Gegenkontaktstück 7 über Kontaktlamellen kontaktiert ist. Das Gegenkontaktstück 7 ist an seinem der Lichtbogenschaltstrecke abgewandten Ende mit einem flachen Kopf 13 versehen, der in zwei von den Lagerwangen 31 gebildeten Gleitbahnen 35 des Gehäuses 30 geführt ist. - Der flach ausgebildete Kopf 13 ist mit einem vertikal zur Koppelstange 27 verlaufenden Langloch 12 versehen.Deviating from the known construction is according to FIG. 2 the coupling rod 27 guided in two bearing cheeks 31, the part of a housing 30 are. This housing is on a contact bridge 32 attached, which to the fixed continuous current contact piece 5 is fixed and the fixed part 33rd of a tubular sliding contact, in which the opposite drivable counter-contact piece 7 via contact blades is contacted. The mating contact piece 7 is on his end facing away from the arc switching path with one provided flat head 13 which in two of the bearing cheeks 31st formed slideways 35 of the housing 30 is guided. - The flat-shaped head 13 is vertical to the coupling rod 27 extending slot 12 provided.

In dem Gehäuse 30 ist auf einer vertikal zur Zeichenebene verlaufenden Welle 38 ein zweiarmiger Steuerhebel 10 gelagert, der an seinem einen Ende gabelförmig gestaltet und an seinem anderen Ende mit einem Zapfen 11 versehen ist. Der Zapfen 11 greift in das Langloch 12 am Kopf 13 ein. Das gabelseitige Ende weist zwei Zinken 16 und 17 auf, die eine maulartige Öffnung 18 bilden, in die der Zapfen 28 der Koppelstange 27 eingreifen kann. Die beiden Zinken 16 und 17 sind außen mit einer Anlagefläche 19 bzw. 20 versehen, mit denen der Steuerhebel 10 - in Abhängigkeit von seiner Stellung - zur Anlage an den Boden 34 des U-förmigen Querschnittsprofils der Koppelstange 27 kommt. Durch Anschläge 36 und 37 im Gehäuse 30 ist dabei gewährleistet, daß der Steuerhebel 10 in der jeweiligen Anlageposition verharrt. Die beiden Anlagepositionen stellen Endpositionen dar, zwischen denen der Steuerhebel 10 unter der Wirkung des Zapfens 28 bewegt wird. Damit das gabelartige Ende hierbei eine Drehbewegung um die Achse 38 ausführen kann, ist die Koppelstange 27 im Boden 34 des U-förmigen Querschnittes mit einem länglichen Schlitz 29 versehen.In the housing 30 is on a vertical to the plane of the drawing extending shaft 38 mounted a two-armed control lever 10, which is forked at one end and on its other end is provided with a pin 11. The Pin 11 engages in slot 12 on head 13. The forked side End has two prongs 16 and 17, one form mouth-like opening 18 into which the pin 28 of the Coupling rod 27 can engage. The two tines 16 and 17 are provided on the outside with a contact surface 19 or 20, with which the control lever 10 - depending on its position - For contact with the bottom 34 of the U-shaped cross-sectional profile the coupling rod 27 comes. Through stops 36 and 37 in the housing 30 ensures that the control lever 10 remains in the respective investment position. The two Investment positions represent end positions between which the control lever 10 moves under the action of the pin 28 becomes. So that the fork-like end here a rotational movement can execute about the axis 38, the coupling rod 27th in the bottom 34 of the U-shaped cross section with an elongated Provide slot 29.

Es kann beispielsweise der Kopf 13 aus einem Isolierstoff, beispielsweise aus glasfaserverstärktem Kunststoff bestehen, um den Strompfad von diesem Ende des Gegenkontaktstücks 7 über die Wangen 31 und die Welle 38 zu dem Gehäuse 30 und zur Kontaktbrücke 32 zu unterbrechen. Zu demselben Zweck kann auch die Welle 38 und/oder ihr Lager oder der Zapfen 28 aus Isolierstoff bestehen.For example, the head 13 can be made of an insulating material, for example made of glass fiber reinforced plastic, around the current path from this end of the mating contact piece 7 over the cheeks 31 and the shaft 38 to the housing 30 and Interrupt contact bridge 32. Can do the same also the shaft 38 and / or its bearing or the pin 28 Insulating material exist.

Zapfen 28, Lagerwangen 31 und Steuerhebel 10 sind als Übertragungselemente Bestandteile des Hilfsgetriebes, das die Antriebsbewegung des antreibbaren Kontaktstückes 9 in eine entgegengesetzte Antriebsbewegung des Gegenkontaktstückes 7 umsetzt.Pins 28, bearing cheeks 31 and control lever 10 are as transmission elements Components of the auxiliary gearbox that drive the motion of the drivable contact piece 9 in an opposite Driving movement of the counter-contact piece 7 converts.

Bei einer Ausschaltbewegung durchläuft die Koppelstange 27 und damit der Zapfen 28 ausgehend von der in Figur 1 dargestellten Position kontinuierlich verschiedene Zwischenpositionen, von denen die Figuren 2 und 3 diejenigen darstellen, die der Kopf 13 und damit das zugehörige angetriebene Gegenkontaktstück 7 kurz vor und kurz nach Erreichen des Geschwindigkeitsmaximums einnehmen, und Figur 5 die andere Endstellung des Steuerhebels 10. Im Anschluß an die Position gemäß Figur 5 kann sich die Koppelstange noch weiter nach links bewegen, ohne daß der Steuerhebel 10 seine Position verändert.When the device is switched off, the coupling rod 27 passes through and thus the pin 28 starting from that shown in Figure 1 Position continuously different intermediate positions, of which Figures 2 and 3 represent those the head 13 and thus the associated driven mating contact piece 7 shortly before and shortly after reaching the maximum speed occupy, and Figure 5 the other end position of the control lever 10. Following the position according to FIG. 5 the coupling rod can move further to the left, without the control lever 10 changing its position.
