Description

Leistungsschalter mit düsenförmiger AusströmöfEnung Zusatz zur Patentanmeldung L 33684 V1II d / 21 c (Auslegeschrift 1126 473) Die Hauptpatentanmeldung bezieht sich auf einen Leistungsschalter mit düsenförmiger Ausströmöffnung für das Löschmittel, bei dem die festen Schaltkontakte durch ein Schutzrohr gegen die Wärmestrahlung des Lichtbogens abgeschirmt werden. Es handelt sich hier um ein unter Federdruck stehendes Isolierrohr aus hoch wärmefestem Material, das an der Löschkammerwand derart gleitend angeordnet ist, daß es sich nach Freigabe des festen Gegenkontaktes vom beweglichen Schaltkontakt vor den Gegenkontakt legt. Beim Einschalten läuft der bewegliche Schaltstift in den Gegenkontakt ein, er trifft hierbei auf das Schuzrohr und schiebt es in, seine Endlage. Bei sehr hohen Einschaltgeschwindigkeiten kann es vorkommen, daß das Schutzrohr infolge des harten Aufpralls des Schaltstiftes aufgestaucht oder verbeult wird, so daß es im Kontakt .steckenbleibt oder andere unangenehme Sörungen auftreten.Circuit breaker with nozzle-shaped outflow opening Addendum to patent application L 33684 V1II d / 21 c (Auslegeschrift 1126 473) The main patent application relates to a circuit breaker with a nozzle-shaped outflow opening for the extinguishing agent, in which the fixed switching contacts are shielded from the thermal radiation of the arc by a protective tube. It is a spring-loaded insulating tube made of highly heat-resistant material, which is arranged to slide on the quenching chamber wall in such a way that, after the fixed mating contact has been released from the movable switching contact, it lies in front of the mating contact. When switching on, the movable switch pin runs into the mating contact, it hits the protective tube and pushes it into its end position. At very high switch-on speeds, it can happen that the protective tube is compressed or dented as a result of the hard impact of the switch pin, so that it sticks in contact or other unpleasant malfunctions occur.

Um diesen Mangel auszuschließen, wird erfindungsgemäß vorgeschlagen, das Schutzrohr mit einem beim Einschalten vom strömenden Medium beaufschlagbaren Antriebskolben zu versehen. Handelt es sich um einen Druckgasschalter, so dient hierzu Druckgas, das während des Einschaltens dem Schutzrohr zweckmäßig über ein Isolierrohr von Erdpotential her zugeleitet wird. Das Schutzrohr wird durch das Druckgas angehoben und fällt erst dann, wenn das Druckgas abgestellt ist, infolge der wirksamen Federkraft auf den Schaltstift zurück. Auf diese Weise kann es zu keiner Zerstörung oder sonstigen Beschädigung des Schutzrohres mehr kommen.In order to rule out this deficiency, it is proposed according to the invention that the protective tube can be acted upon by the flowing medium when it is switched on To provide drive piston. If it is a pressurized gas switch, then it is used for this purpose, pressurized gas, which is expediently supplied to the protective tube during switching on Insulating pipe is fed from earth potential. The protective tube is through the Pressurized gas is raised and only falls when the pressurized gas is turned off, as a result the effective spring force on the switch pin. That way it can too there is no longer any destruction or other damage to the protective tube.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Innerhalb des Rohres 1 eines Druckgasschalters befindet sich die Schaltstrecke mit dem festen Durchlaufkontakt 2 und dem beweglichen Schaltstift 3. Das Schuzrohr 4 ist an seinen Gleitstellen als Kolben ausgebildet und mit Dichtungsringen 5 versehen. Zum Anheben des Schutzrohres wird seinem Antriebskolben über das Isolierrohr 6 Druckluft zugeführt. Nach Auffüllung des Raumes 7 bewegt sich das Schutzrohr 4 gegen die Federkraft in Richtung der Gegenelektrode 8 und gibt dabei den Durchlaufkontakt 2 frei. Der Schaltstift 3 kann nun in den Durchlaufkontakt eingreifen, ohne auf das Schutzrohr zu treffen. Mit 9 ist der lichtbogenfeste Teil des Schutzrohres bezeichnet.The switching path with the fixed flow contact 2 and the movable switching pin 3 is located inside the tube 1 of a compressed gas switch. The protective tube 4 is designed as a piston at its sliding points and is provided with sealing rings 5. To lift the protective tube, its drive piston is supplied with compressed air via the insulating tube 6. After the space 7 has been filled, the protective tube 4 moves against the spring force in the direction of the counter electrode 8 , thereby releasing the through contact 2. The switch pin 3 can now engage in the flow contact without hitting the protective tube. The arc-proof part of the protective tube is designated by 9.

Das Antriebsmittel für das Schutzrohr wird normalerweise von der Einschaltluft abgezweigt und mittels einer besonderen Leitung in das Schaltrohr 1 ein.-geführt. Bei Schaltern, die einen angemessenen Abstand zwischen dem: Rohr 1 und dem Grundgestell besitzen, kann die Einführung der Leitung 6 auf der dem Erdpotential zugewandten Seite erfolgen. Handelt es sich jedoch um einen voll isolierten Schalter, der unmittelbar mit seinem Rohr 1 an dem metallischen Tragrahmen anliegt, so wird das Rohr 6, um einen ausreichenden Kriechweg herzustellen, an der dem Erdpotential abgewandten Seite des Rohres 1 eingeführt.The drive means for the protective tube is normally from the switch-on air branched off and inserted into the switching tube 1 by means of a special line. For switches that have a reasonable distance between: Tube 1 and the base frame own, the introduction of the line 6 on the face of the earth potential Side. However, if it is a fully isolated switch, the immediate rests with its tube 1 on the metallic support frame, so the tube 6 to to establish a sufficient creepage path at the point facing away from the earth potential Side of the tube 1 inserted.
