Description

Die Erfindung betrifft einen Trennschalter für eine Schaltanlage mit einem Trennschalterfestkontakt, einem Trennschalterbewegkontakt und einer Trennschalterantriebswelle, welche mittels einer isolierenden Koppelstange mit dem Trennschalterbewegkontakt mechanisch gekoppelt ist, wobei der Trennschalterfestkontakt, der Trennschalterbewegkontakt und das Drehzentrum der Trennschalterantriebswelle linear angeordnet sind und die Trennschalterantriebswelle und die Koppelstange für eine 180°-Drehung der Trennschalterantriebswelle ausgeführt sind.The invention relates to a circuit breaker for a switchgear with a circuit breaker fixed contact, a Trennschalterbewegkontakt and a Trennschalterantriebswelle which is mechanically coupled by means of an insulating coupling rod with the Trennschalterbewegkontakt, the Trennschalterbewegkontakt, the Trennschalterbewegkontakt and the center of rotation of the disconnector drive shaft are arranged linearly and the disconnector drive shaft and the coupling rod are designed for a 180 ° rotation of the disconnector drive shaft.

Ein derartiger Trennschalter ist aus der EP 0 414 192 A2 bekannt.Such a circuit breaker is from the EP 0 414 192 A2 known.

Aus dem landläufigen Stand der Technik ist es bekannt, bei einer Schaltanlage mit einem Leistungsschalter diesen auf einem Einschub anzuordnen und mit lösbaren Kontakten zu versehen, so dass beim Verfahren des Einschubs aus einer Kontaktstellung in eine Trennstellung durch Lösen der lösbaren Kontakte eine Trennstrecke und somit ein Trennschalter ausgebildet ist.From the common state of the art, it is known in a switchgear with a circuit breaker to arrange this on a slot and provided with detachable contacts, so that when moving the insert from a contact position to a release position by releasing the detachable contacts a separation distance and thus a Isolating switch is formed.

Aus der DE 10 2007 038 898 B3 ist ein Trennschalter bekannt, bei welchem ein Trennschalterfestkontakt in Form eines Bolzens und ein Trennschalterbewegkontakt in Form einer beweglichen Hülse zum Schalten bzw. Ausbilden einer Trennstrecke vorgesehen sind, wobei die Hülse mit einer Antriebseinrichtung verbunden ist und bewegbar ausgebildet ist.From the DE 10 2007 038 898 B3 a circuit breaker is known in which a breaker switch fixed contact in the form of a bolt and a Trennschalterbewegkontakt are provided in the form of a movable sleeve for switching or forming a separation distance, wherein the sleeve is connected to a drive device and is designed to be movable.

Aufgabe der vorliegenden Erfindung ist es, einen Trennschalter für eine Schaltanlage auszubilden, welcher einen kompakten und Platz sparenden Aufbau ermöglicht.Object of the present invention is to provide a circuit breaker for a switchgear, which allows a compact and space-saving design.

Erfindungsgemäß gelöst wird diese Aufgabe bei einem Trennschalter der eingangs genannten Art dadurch, dass die Koppelstange an ihrem oberen Ende drehgelenkig mit dem Trennschalterbewegkontakt und an ihrem unteren Ende drehgelenkig mit einem Ausleger der Trennschalterantriebswelle verbunden ist und einen Isolatorabschnitt und einen Ringsegmentabschnitt aufweist.This object is achieved according to the invention in a circuit breaker of the type mentioned in that the coupling rod is pivotally connected at its upper end to the Trennschalterbewegkontakt and at its lower end pivotally connected to a boom of the disconnector drive shaft and having an insulator portion and a ring segment portion.

Ein derartiger Trennschalter weist einen Platz sparenden und kompakten Aufbau auf, weil alle wesentlichen Elemente linear zueinander angeordnet oder mit anderen Worten auf einer Linie angeordnet sind, so dass bezüglich einer seitlichen Ausdehnung des Trennschalters ein minimaler Platzbedarf benötigt ist. Die Ausbildung der Trennschalterantriebswelle und der Koppelstange für eine 180°-Drehung ist besonders vorteilhaft, weil dadurch zwischen einer Einschaltstellung des Trennschalters mit leitender Verbindung von Trennschalterfestkontakt und Trennschalterbewegkontakt und einer Ausschaltstellung des Trennschalters mit einer Trennstrecke zwischen dem Trennschalterfestkontakt und einem Trennschalterbewegkontakt bei Drehung der Antriebswelle um 180° die Einschaltstellung des Trennschalters und die Ausschaltstellung des Schalters jeweils so genannte Totpunkte der Antriebskinematik darstellen, so dass sich der Antrieb in seinen Endlagen der Einschaltstellung und der Ausschaltstellung des Trennschalters selbst blockiert, und somit auf aufwändige und raumgreifende zusätzliche Verriegelungsmechanismen für den Trennschalter in seiner Einschaltstellung oder in seiner Ausschaltstellung verzichtet werden kann.Such a circuit breaker has a space-saving and compact construction, because all the essential elements are arranged linearly to one another or in other words are arranged in a line, so that with respect to a lateral extent of the circuit breaker a minimum space is required. The formation of the disconnector drive shaft and the coupling rod for a 180 ° rotation is particularly advantageous because characterized between a closed position of the circuit breaker with conductive connection of disconnector fixed contact and Trennschalterbewegkontakt and a disconnected position of the circuit breaker with a separation distance between the circuit breaker fixed contact and a Trennschalterbewegkontakt upon rotation of the drive shaft 180 °, the closed position of the circuit breaker and the off position of the switch represent each so-called dead center of the drive kinematics, so that the drive blocked in its end positions of the closed position and the open position of the circuit breaker itself, and thus to complex and expansive additional locking mechanisms for the circuit breaker in his Closed position or can be dispensed in its off position.

Durch einen derartigen Ringsegmentabschnitt der Koppelstange ist ein Platz sparender Aufbau ermöglicht, weil sich dieses Ringsegment der Koppelstange in einer Ausschaltstellung um die Antriebswelle herum angeordnet befindet. Durch den Isolatorabschnitt der Koppelstange ist eine dielektrische Trennung von Kontaktsystem des Trennschalters und Antriebswelle ausgebildet.By such a ring segment portion of the coupling rod a space-saving design is possible because this ring segment of the coupling rod is disposed in an open position around the drive shaft around. Through the insulator portion of the coupling rod, a dielectric separation of contact system of the circuit breaker and drive shaft is formed.

In weiterer Ausführung der Erfindung ist der Trennschalterbewegkontakt als in einer leitenden Führungshülse geführter Trennschalterbolzen ausgeführt. Ein derartiger Trennschalterbolzen ist eine besonders einfache Form eines Trennschalterbewegkontaktes, wobei über die leitende Führungshülse einerseits eine mechanische Führung und andererseits eine elektrisch leitende Verbindung des Trennschalterbolzens mit weiteren stromführenden Teilen ermöglicht ist.In a further embodiment of the invention, the Trennschalterbewegkontakt is designed as guided in a conductive guide sleeve disconnect switch pin. Such a disconnect switch pin is a particularly simple form of a Trennschalterbewegkontaktes, on the one hand, a mechanical guide and on the other hand, an electrically conductive connection of the disconnect switch pin is made possible with further current-carrying parts on the one hand.

In einer bevorzugten Ausführungsform der Erfindung ist der Trennschalterfestkontakt als Hülse zur Aufnahme des Trennschalterbolzens in der geschlossenen Stellung des Trennschalters ausgeführt.In a preferred embodiment of the invention, the circuit breaker fixed contact is designed as a sleeve for receiving the disconnect switch pin in the closed position of the circuit breaker.

In einer besonders bevorzugten Ausführungsform ist die Führungshülse mit einem Verbindungsmittel leitend verbunden, welches Verbindungsmittel zum Anschluss von Kontakten eines Erdungsschalters und/oder eines Leistungs- oder Lastschalters vorgesehen ist.In a particularly preferred embodiment, the guide sleeve is conductively connected to a connecting means, which connecting means for connecting contacts of a grounding switch and / or a power or load switch is provided.

Der Trennschalterbewegkontakt 3 ist weiterhin über eine isolierende Koppelstange mit einer Trennschalterantriebswelle 9 mechanisch gekoppelt, wobei die isolierende Koppelstange 8 an ihrem oberen Ende 10 und an ihrem unteren Ende 11 jeweils drehgelenkig mit dem Trennschalterbewegkontakt 3 bzw. einem Ausleger 12 der Trennschalterantriebswelle 9 verbunden ist, so dass bei einer Drehung der Trennschalterantriebswelle 9 über die drehgelenkige Verbindung der isolierenden Koppelstange 8 mit dem Trennschalterbewegkontakt 3 eine lineare Führung des Trennschalterbewegkontaktes 3 in der Führungshülse 4 zum Überführen aus der in der Figur 1 dargestellten Einschaltstellung des Trennschalters 1 in eine Ausschaltstellung ermöglicht ist, welche mit Bezug auf die Figur 2 näher erläutert wird. Die isolierende Koppelstange 8 weist einen Isolatorabschnitt 13 auf, welcher eine dielektrische Trennung zwischen dem stromführenden Trennschalter 1 und der Trennschalterantriebswelle 9 gewährleistet, sowie einen Ringsegmentabschnitt 14, welcher sich, wie mit Bezug auf die Figur 2 weiter unten näher erläutert, nach Ausführung eines Ausschaltvorganges unter Ausbildung einer Trennstrecke zwischen Trennschalterfestkontakt 2 und Trennschalterbewegkontakt 3 um die Trennschalterantriebswelle 9 herum angeordnet befindet.The Trennschalterbewegkontakt 3 is further mechanically coupled via an insulating coupling rod with a disconnect switch drive shaft 9, wherein the insulating coupling rod 8 at its upper end 10 and at its lower end 11 each pivotally connected to the Trennschalterbewegkontakt 3 and a boom 12 of the disconnector drive shaft 9, so that upon rotation of the disconnector drive shaft 9 via the pivotal connection of the insulating coupling rod 8 with the Trennschalterbewegkontakt 3, a linear guide of the Trennschalterbewegkontaktes 3 in the guide sleeve 4 for transferring from in the FIG. 1 illustrated switch-on position of the circuit breaker 1 in an open position is possible, which with respect to the FIG. 2 is explained in more detail. The insulating coupling rod 8 has an insulator portion 13, which ensures a dielectric separation between the current-carrying disconnector 1 and the disconnector drive shaft 9, and a ring segment portion 14, which, as with respect to the FIG. 2 explained in more detail below, after execution of a switch-off process to form a separation line between disconnect switch fixed contact 2 and disconnect switch contact 3 is disposed around the disconnect switch drive shaft 9 around.

Figur 2 zeigt eine perspektivische Ansicht des Trennschalters 1 der Figur 1 mit einer dreiphasigen Ausführung mit Phasen L1, L2 und L3, welche über gleiche Komponenten verfügen und von denen in der Schnittansicht der Figur 1 nur eine Phase L1 dargestellt ist und beschrieben wurde und mit Bezug auf die Figur 2 ebenfalls nur die Phase L1 bezeichnet und beschrieben wird. In der Figur 2 befindet sich der Trennschalter 1 in seiner Ausschaltstellung, das heißt über eine figürlich nicht dargestellte Antriebseinheit wurde eine Drehbewegung in die Trennschalterantriebswelle 9 eingeleitet, so dass über eine 180°-Drehung der Trennschalterantriebswelle 9 sich der Ringsegmentabschnitt 14 um die Trennschalterantriebswelle 9 herum angeordnet befindet und über die 180°-Drehbewegung der Trennschalterantriebswelle 9 der Trennschalterbewegkontakt 3 in Form des Trennschalterbolzens in seiner Ausschaltstellung befindet, so dass zwischen dem Trennschalterbolzen und dem Trennschalterfestkontakt 2 eine Trennstrecke d ausgebildet ist, welche zur dielektrischen Trennung von Trennschalterfestkontakt 2 und Trennschalterbewegkontakt 3 dient. Figürlich nicht dargestellt in der Figur 2 sind mit den Trennschalterfestkontakten 2 verbundene Sammelschienenanschlüsse einer figürlich ebenfalls nicht dargestellten Schaltanlage sowie an dem Verbindungsmittel 5 in Form des Strombandes anschließbare weitere Schaltgeräte wie Erdungs- und/oder Leistungs- oder Lastschalter, welche mit Kabelanschlüssen der Schaltanlage verbindbar sind.
