Description

Gegenstand des Hauptpatents ist ein elektrischer Schalter für Wechselstrom mit Lichtbogenlöschung nach dem Expansionsprinzip durch vom Lichtbogen selbst aus Flüssigkeit entwickeltem und rasch im Lichtbogenraum expandierendem Dampf, dessen Unterbrechungsstrecke in Gas angeordnet ist und im dessen Lichtbogenb ereich fLüssigkeitsdurchtränkte Körper gebracht sind.The subject of the main patent is an electrical switch for alternating current with arc extinguishing according to the expansion principle through liquid developed by the arc itself and rapidly in the arc chamber expanding steam, the interruption path of which is arranged in gas and in the arc area of which has been brought to a liquid-soaked body.

Erfindungsgemäß sollen diese Körper aus porösem keramischem Material bestehen. Dieses Material vereinigt drei für den vorliegenden Zweck besonders wesentliche Eigenschaften. Es hat nämlich, eine hohe Saugfähigkeit, ist ein guter Isolator und außerdem sehr hitzebeständig, so daß es dem Lichtbogen gut widersteht. Außerdem ist das keramische Material wegen seiner Festigkeitseigenschaften' als Baustoff gut geeignet. Ins- According to the invention, these bodies should consist of porous ceramic material. This Material combines three properties that are particularly important for the present purpose. Namely, it has a high absorbency, is a good insulator and besides very heat resistant so that it withstands the arc well. Besides, it's ceramic Material because of its strength properties' well suited as a building material. Into the-

ao besondere eignet sich schamotteähnliches Material (Thermisol).Ao special is fireclay-like material (Thermisol).

Das feste Schaltstück kann' beispielsweise in einem Zylinder aus dem porösen keramischen Material angeordnet sein, der in ein Gefäß mit Schaltflüssigkeit !eintaucht. Der Zylinder aus keramischem Material wird dann immer mit der SchaltfLüssigkeit durchtränkt sein, so daß er unter der Einwirkung des Lichtbogens reichliche Mengen Dampf abgibt.The fixed contact can 'for example in a cylinder made of the porous ceramic Material be arranged that is immersed in a vessel with switching fluid! Of the The cylinder made of ceramic material is then always saturated with the switching fluid so that it gives off copious amounts of vapor under the action of the arc.
