Description
Die vorliegende Erfindung bezieht sich auf eine Hochstromschaltvorrichtung nach dem Oberbegriff von Patentanspruch 1. Ein solche Hochstromschaltvorrichtung weist einen Generatorschalter und einen dem Generatorschalter nachgeschalteten Trennschalter auf. Der Trennschalter kann als eigenständiges Gerät gebaut und in die Hochstromschaltvorrichtung eingebaut werden, ist aber im allgemeinen als integrierender Bestandteil der Vorrichtung ausgebildet und bildet mit dem Generatorschalter eine Baueinheit, in der der Generatorschalter ein längs einer Achse ausgerichtetes Löschkammergehäuse mit zwei voneinander elektrisch isolierten Stromanschlussgehäusen aufweist, von denen das erste mit einem Generator elektrisch leitend verbindbar und das zweite in den Trennschalter integriert ist. Der Trennschalter enthält eine Kontaktanordnung mit einem als Kontaktring ausgebildeten feststehenden und einem als Kontaktrohr ausgebildeten beweglichen Kontakt. Bei geschlossenem Trennschalter kontaktiert das Kontaktrohr den Kontaktring elektrisch leitend. Bei geöffnetem Trennschalter ist das Kontaktrohr unter Bildung einer vorgeschriebenen luftisolierten Trennstrecke mit Abstand zum Kontaktring gehalten.The present invention relates to a high-current switching device according to the preamble of claim 1. Such a high-current switching device has a generator switch and a circuit breaker connected downstream of the generator switch. The circuit breaker can be built as a standalone device and built into the high current switching device, but is generally formed as an integral part of the device and forms with the generator switch a unit in which the generator switch has an axis aligned quenching chamber housing with two electrically isolated from each other power connector housings, of which the first electrically conductively connected to a generator and the second is integrated in the circuit breaker. The circuit breaker includes a contact assembly having a contact ring formed as a stationary and a contact formed as a movable contact. When the circuit breaker is closed, the contact tube contacts the contact ring in an electrically conductive manner.

Eine Hochstromschaltvorrichtung der eingangs genannten Art mit einem Generator- und einem Trennschalter ist beschrieben in der Produktbroschüre "Generator Circuit-Breakers Application Guide" von ABB Switzerland Ltd, Zürich Schweiz, Copyright ABB, 1HC007919 E02-S/AA10. Der Trennschalter dieser Hochstromschaltvorrichtung weist zwei in sich geschobene Zylinder auf, von denen einer feststehend in der Hochstromschaltvorrichtung gehalten ist und als Gehäuse des Trennschalters dient, wohingegen der andere mit Hilfe eines mechanischen Antriebs längs einer Achse der Hochstromschaltvorrichtung verschiebbar im Trennschaltergehäuse gelagert ist. Dieser teleskopartig verschiebbare Zylinder ist in elektrisch leitender Weise mit dem Trennschaltergehäuse verbunden und wirkt als beweglicher Kontakt einer Kontaktanordnung des Trennschalters. Ein feststehender Kontakt der Kontaktanordnung ist in ein Stromanschlussgehäuse des Generatorschalters integriert. Bei geschlossenem Trennschalter ist das Kontaktrohr in den Kontaktring eingeschoben und verbindet dann den Generatorschalter mit einem am Trennergehäuse angebrachten Stromanschluss. Beim Öffnen trennt sich das Kontaktrohr vom Kontaktring. Eine sich dabei bildende luftisolierte Trennstrecke isoliert den Generatorschalter und damit einen mit dem Generatorschalter elektrisch leitenden verbindbaren Generator vom Stromanschluss des Trennschalter und damit von einen mit diesem Stromanschluss elektrisch leitend verbindbaren Transformator eines Hochspannungsnetzes.A high current switching device of the type mentioned above with a generator and a circuit breaker is described in the product brochure "Generator Circuit Breakers Application Guide" by ABB Switzerland Ltd, Zurich Switzerland, Copyright ABB, 1HC007919 E02-S / AA10. The circuit breaker of this high-current switching device has two pushed-in cylinder, from one of which is fixedly held in the high current switching device and serves as a housing of the circuit breaker, whereas the other by means of a mechanical drive along an axis of the high current switching device is slidably mounted in the circuit breaker housing. This telescopically displaceable cylinder is electrically connected to the circuit breaker housing and acts as a movable contact of a contact arrangement of the circuit breaker. A fixed contact of the contact arrangement is integrated in a power connector housing of the generator switch. When the circuit breaker is closed, the contact tube is inserted into the contact ring and then connects the generator switch with a power connector attached to the disconnector housing. When opening, the contact tube separates from the contact ring. A thereby forming air-insulated separation line isolates the generator switch and thus an electrically conductive with the generator switch connectable generator from the power connector of the circuit breaker and thus from an electrically connected to this power connector transformer of a high voltage network.
