Description

Leistungsschalter mit Lichtbogenlöschung durch ein strömendes Löschmittel und mit einer Abschirmvorrichtung des Düsenkontaktes Zusatz zur Patentanmeldung L 33684 VIII d / 21 c 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. Während das Schutzrohr bei dem Schalter nach der Hauptpatentanmeldung an der Löschkammerwand unter Federdruck gleitend angeordnet ist und sich nach Freigabe des festen Gegenkontaktes vom beweglichen Schaltkontakt zur Abschirmung der Wärmestrahlung vor den Gegenkontakt legt, sieht die Erfindung vor, die Abschirmung feststehend und den Düsenkontakt derart beweglich anzuordnen, daß er sich während des Ausschaltens hinter die Abschirmung legt. Beispielsweise bei einem Druckgasschalter wird dabei der feste Düsenkontakt von dem Druckgas hinter die Abschirmung bewegt. Auf diese Weise wird eine mechanische Beschädigung der Abschirmung vermieden, wie sie bei dem Schalter nach der Hauptpatentanmeldung bei hohen Schaltgeschwindigkeiten durch den auf das Schutzrohr treffenden Schaltstift vorkommen kann.Circuit breaker with arc extinguishing by a flowing extinguishing agent and with a shielding device for the nozzle contact addendum to the patent application L 33684 VIII d / 21 c The main patent application relates to a circuit breaker with nozzle-shaped outflow opening for the extinguishing agent, in which the fixed switching contacts shielded from the thermal radiation of the arc by a protective tube. While the protective tube at the switch according to the main patent application on the extinguishing chamber wall is arranged slidably under spring pressure and after releasing the fixed mating contact from the moving switch contact to the shielding of thermal radiation from the counter contact The invention provides for the shield to be fixed and the nozzle contact to be moveable in such a way that it is behind the shield during switching off lays. In the case of a pressure gas switch, for example, the fixed nozzle contact becomes moved by the pressurized gas behind the shield. This way it becomes a mechanical one Damage to the shield avoided, as is the case with the switch according to the main patent application at high switching speeds by the switch pin hitting the protective tube can occur.

Mit der Erfindung ist auch der Vorteil verbunden, daß mit der Bewegung des Düsenkontaktes: hinter die Abschirmung gleichzeitig die günstigste Löschstellung erreicht werden kann, während der Gegenkontakt dann, in entgegengesetzter Richtung bewegt, die notwendige Spannungstrennstrecke herstellt.The invention also has the advantage that with the movement of the nozzle contact: behind the shielding at the same time the most favorable extinguishing position can be achieved while the mating contact then, in the opposite direction moves, establishes the necessary voltage isolating path.

Die Zeichnung zeigt die Erfindung an einem schematisch gehaltenen Ausführungsbeispiel bei einem Druckgasschalter.The drawing shows the invention on a schematic Exemplary embodiment with a gas pressure switch.

Innerhalb eines die Schaltstrecke enthaltenden Rohres 1 ist fest mit dessen Wandung verbunden das metallische oder auch aus Isolierstoff bestehende Schutzrohr 2 angebracht. Unterhalb dieses Schutzrohres befinden sich die Gegenkontakte 3, die mit dem Schaltstift 4 zusammenarbeiten. Die Kontakte 3 können unter Federdruck stehen, derart, daß sie nach dem Ausschaltvorgang wieder in ihre ursprüngliche Stellung zurückbewegt werden. Beim Ausschalten bewegt die einströmende Druckluft die Kontakte 3 in die obere schraffiert gezeichnete Lage, in der sie hinter dem Schutzrohr 2 liegen und vor der Wärmestrahlung sowie dem Lichtbogen selbst geschützt sind. Der Schaltstift 4 wird zweckmäßig so ausgeführt, daß sein kontaktgebender Teil einen größeren Durchmesser erhält als sein Schaft, so daß das Gewicht des Schaltstiftes kleiner wird. Die Kontakte 3 können ferner so ausgebildet sein, daß nur der Teil, der mit dem Schaltstift in Berührung kommt, Kontaktmaterial enthält.Inside a tube 1 containing the switching path is fixed with whose wall is connected to the metallic or insulating tube 2 attached. Below this protective tube are the mating contacts 3, the work together with switching pin 4. The contacts 3 can be under spring pressure, in such a way that they return to their original position after the switch-off process be moved back. When switching off, the incoming compressed air moves the contacts 3 in the upper hatched position, in which it is behind the protective tube 2 and are protected from thermal radiation and the arc itself. Of the Switching pin 4 is expediently designed so that its contacting part has a gets larger diameter than its shaft, so that the weight of the switch pin gets smaller. The contacts 3 can also be designed so that only the part that comes into contact with the switch pin contains contact material.

Bei einem Schalter mit unter Druck stehendem öl als Löschmittel ist der Aufbau grundsätzlich der gleiche.In the case of a switch with pressurized oil as an extinguishing agent the structure is basically the same.
