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 circuit breaker 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 DE 10 2007 038 898 B3 a circuit breaker is known, in which a breaker 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 path, wherein the sleeve is connected to a drive device and formed movable is.
Aufgabe der vorliegenden Erfindung ist es, einen Trennschalter für eine Schaltanlage auszubilden, welcher einen kompak- ten und Platz sparenden Aufbau ermöglicht. Object of the present invention is to form a circuit breaker for a switchgear, which allows a compact and space-saving design.
Erfindungsgemäß gelöst wird diese Aufgabe durch einen Trennschalter 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 die Trennschalterantriebswelle linear angeordnet sind und die Trennschalterantriebswelle und die Koppelstange für eine 180°-Drehung ausgeführt sind. According to the invention this object is achieved by a circuit breaker with a disconnector fixed contact, a Trennschalterbewegkontakt and a Trennschalterantriebswelle which is mechanically coupled by means of an insulating coupling rod with the Trennschalterbewegkontakt, the Trennschalterfestkontakt, the Trennschalterbewegkontakt and the disconnector drive shaft are arranged linearly and the Disconnector drive shaft and the coupling rod are designed for a 180 ° rotation.
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 Trenn- schalterfestkontakt 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 Einschalt- Stellung 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 isolator switch fixed contact and a Trennschalterbewegkontakt during rotation of Drive shaft by 180 °, the closed position of the circuit breaker and the off position of the switch each so-called dead centers of the drive kinematics, so that the drive blocks in its end positions of the switch-on and off position of the circuit breaker itself, and thus on consuming and expansive additional locking mechanisms for the circuit breaker can be dispensed with in its closed position or in its open position.
In einer vorteilhaften Ausgestaltung der Erfindung weist die Koppelstange einen Isolatorabschnitt und einen Ringsegmentabschnitt auf. 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. In an advantageous embodiment of the invention, the coupling rod has an insulator section and a ring segment section. 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.
Durch den Isolatorabschnitt der Koppelstange ist eine dielektrische Trennung von Kontaktsystem des Trennschalters und Antriebswelle ausgebildet. In weiterer Ausführung der Erfindung ist der Trennschalterbewegkontakt als in einer leitenden Führungshülse geführter Trennschalterbolzen ausgeführt. Ein derartiger Trennschalter- bolzen 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. Through the insulator portion of the coupling rod, a dielectric separation of contact system of the circuit breaker and drive shaft is formed. In a further embodiment of the invention, the Trennschalterbewegkontakt is designed as guided in a conductive guide sleeve disconnect switch pin. Such a circuit breaker bolt is a particularly simple form of a disconnector switch moving contact, wherein on the one hand, a mechanical guide and on the other hand, an electrically conductive connection of the disconnect switch pin with other current-carrying parts is made possible via the conductive guide sleeve.
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 iso- lierende 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 Ein- schaltstellung 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 Trennschal- terantriebswelle 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 Trenn- schalterfestkontakt 2 und Trennschalterbewegkontakt 3 um die Trennschalterantriebswelle 9 herum angeordnet befindet.
