Description

Leistungsschalter mit vom Lichtbogen erzeugten Löschgasen Die Erfindung betrifft Leistungsschalter, in welchen Teile der Lichtbogenlöschkammer aus-Stoffen hergestellt oder mit solchen belegt sind, die unter der Einwirkung des Lichtbogens Gase abgeben, welche zur Löschung dieses Lichtbogens beitragen.Circuit breaker with extinguishing gases generated by the arc The invention relates to circuit breakers in which parts of the arc chamber are made of substances manufactured or covered with such that are exposed to the action of the arc Release gases which contribute to extinguishing this arc.

Gemäß der Erfindung benutzt man zur Herstellung oder zur Belegung der Wände der Löschkammern Polymere des Formaldehyds, die Ketten von Polyoxymethylenmolekülen bilden und die unter der Einwirkung des Lichtbogens Gase abgeben.According to the invention, it is used for production or for occupancy the walls of the arcing chambers are polymers of formaldehyde, the chains of polyoxymethylene molecules and which emit gases under the action of the arc.

Die Polymere des Formaldehyds, die Ketten aus Polyoxymethylenmolekülen der Formel (CH20)n bilden und folgendermaßen dargestellt werden können: zeichnen sich nicht nur durch gute mechanische und elektrische Eigenschaften, sondern auch durch ihre Fähigkeit aus, unter der Einwirkung des Lichtbogens bedeutende Gasmengen abgeben zu können.The polymers of formaldehyde that form chains of polyoxymethylene molecules of the formula (CH20) n and can be represented as follows: are not only characterized by good mechanical and electrical properties, but also by their ability to give off significant amounts of gas under the action of the electric arc.

Ein weiterer Vorteil der Anwendung dieser Formaldehydpolymere besteht darin, daß sich auf ihnen nach Kontakt mit dem Lichtbogen keine Kohleablagerungen bilden, so daß die Oberflächen der Löschkammerwände, die aus diesem Material bestehen, ihre ursprüngliche Isolierungsfähigkeit in unverminderter Höhe beibehalten.There is another advantage of using these formaldehyde polymers in that there are no carbon deposits on them after contact with the arc form so that the surfaces of the arcing chamber walls, which consist of this material, retain their original insulation ability at the same height.

Es ist leicht ersichtlich, daß das Nichtauftreten von Kohleablagerungen die Anwendung der Polymere des Formaldehyds für die Herstellung oder Belegung der mit dem Lichtbogen in Berührung kommenden Teile der Lichtbogenlöschkammern auch dann vorteilhaft erscheinen läßt, wenn die hohe Gasabgabefähigkeit dieses Materials für den Löschprozeß keine wesentliche Rolle spielt.It is easily seen that the non-occurrence of carbon deposits the application of the polymers of formaldehyde for the production or covering of the parts of the arc extinguishing chambers that come into contact with the arc also then makes appear advantageous if the high gas release capacity of this material plays no essential role in the deletion process.
