Description

Schalter mit Löschung des Liditbpgens durch einen Druckgasstrom Im Hauptpatent 6oi 563 ist ein elektrischer Schalter für hohe Abschaltleistungen beschrieben, bei dem der Unterbrechungslichtbogen durch einen Gasstrom gelöscht wird, der in einer allseitig geschlossenen und unter :einem Vordruck stehenden Kammer durch den Lichtbogen selbst erzeugt wird.. Die Druckkammer ist dabei mit einem von, der Schalterkontaktbewegung unabhängigen, Absperrorgan versehen, welches eine Gasströmung erst von einem bestimmten Überdruck in der Kammer an gestattet. Mit einer derartigen Einrichtung lassen sich zwar Abschaltungen mit sehr guter Lichtbogenlöschung erzielen: Man kann jedoch die Dauer der vollständigen Löschung des Lichtbogens. noch weiter abkürzen und trotzdem noch wesentlich größere Abschaltleistungen beherrschen, wenn man gemäß der Erfindung die Schaltkammer mit einem Druckbehälter (Kohlensäureflasche, Druckgasbehälter) in Verbindung setzt und in der Verbindungsleitung zwischen Schaltkammer und Druckvorratsbehälter ein Reduzierventil anordnet, das, auf einen Gasdruck eingestellt ist, welcher geringer als der vom Absperrorgan ausgeübte Gegendruck ist. Diese Anordnung hat den Vorteil, daß in jedem Augenblick auch nach mehreren. kurzseitig nacheinander folgenden Abschaltungen der Schalter betriebsbereit ist, da in der Schaltkammer verbrauchtes Gas sofort nachgeliefert wird.Switch with deletion of the liditbpgen by a pressurized gas stream Im Main patent 6oi 563 describes an electrical switch for high breaking capacities, in which the interruption arc is extinguished by a gas stream flowing into a chamber closed on all sides and under: a pre-pressure through the Arc itself is generated .. The pressure chamber is thereby with one of the switch contact movement independent, shut-off device, which a gas flow only from a certain Overpressure allowed in the chamber. With such a device can It is true that shutdowns can be achieved with very good arc quenching: However, the Duration of the complete extinction of the arc. Shorten it even further and still still master significantly larger shutdown powers if one according to the invention the switching chamber with a pressure vessel (carbon dioxide bottle, pressurized gas container) in connection and in the connecting line between the switching chamber and the pressure reservoir a reducing valve is arranged, which is set to a gas pressure which is lower than the back pressure exerted by the shut-off device. This arrangement has the advantage that at every moment even after several. short-term successive shutdowns the switch is ready for operation because the gas in the switching chamber is used up immediately is subsequently delivered.

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

In der SchaItkarnmer i sind der feste Kontakt a und der bewegliche Kontakt 3 angeordnet. Die Schaltkammer wird durch ein, oberhalb des festen Kontaktes z angeordnetes kraftschlüssiges Ventils geschlossen gehalten, das nur dann anspricht, wenn der Druck in der Kammer den Gegendruck des Ventils überwiegt. Durch eine Rohrleitung 6 stehty die Schaltkammer mit einem Druckgasvorratsbehälter 7 (Kohlensäureflasche) in Verbindung. In der Rohrleitung befindet sich ein Reduzierventil8, das auf einen Gasdruck eingestellt ist, welcher kleiner als der vom Absperrorgan 5 ausgeübte Gegendruck, ist. Dies hat zur Folge, daß das Reduzierventil geschlossen bleibt, so lange der Druck im Innern der Schaltkammer nicht unter den eingestellten Wert sinkt.In the switch chamber i are the fixed contact a and the movable one Contact 3 arranged. The switching chamber is created by a, above the fixed contact z arranged non-positive valve kept closed, which only responds when when the pressure in the chamber outweighs the back pressure of the valve. Through a pipeline 6 is the switching chamber with a pressurized gas storage container 7 (carbon dioxide bottle) in connection. There is a reducing valve8 in the pipeline, which Gas pressure is set, which is less than the counter pressure exerted by the shut-off device 5, is. This has the consequence that the reducing valve remains closed as long as the The pressure inside the switching chamber does not fall below the set value.

Die Wirkungsweise ist folgende: Sinkt entweder nach einer Abschaltung oder aus anderen Gründen der in der Schaltkammer i vorhandene Gasdruck unter den am Reduzierventi18 eingestellten Wert, so wird sofort aus dem Vorratsbehälter 7 über das Ventil 8 Jer Schaltkammer i neuer Druck zugeführt. Der Schalter isst daher stets betriebsbereit.The mode of action is as follows: either decreases after a shutdown or for other reasons, the gas pressure present in the switching chamber i is below the The value set on the reducing valve 18, then immediately from the storage tank 7 New pressure is supplied to the switching chamber i via the valve 8. The counter therefore eats always ready for use.
