AUSGEGEBENAM 12. MÄRZ 1953ISSUED MARCH 12, 1953

Die Erfindung betrifft einen elektrischen Stromunterbrecher, insbesondere Schalter, mit Lichtbogenlöschung durch Gase und Dämpfe, die durch die Lichtbogeneinwirkung aus festen gasabgebenden Schaltkammerwandungen erzeugt werden. Derartige Stromunterbrecher sind an sich bekannt. Sie verwenden als gasabgebende Aufbaustoffe für die Schaltkammerwandungen Fiber, Borsäure oder Ammoniumalaun, welche jedoch dieser Aufgabe aus verschiedenen Gründen nicht gewachsen sind.The invention relates to an electrical circuit breaker, in particular a switch, with arc extinguishing through gases and vapors that emit solid gas through the effects of the arc Switching chamber walls are generated. Such circuit breakers are known per se. You use fiber, boric acid or as gas-emitting building materials for the switching chamber walls Ammonium alum, which, however, is not up to the task for various reasons.

Gemäß der Erfindung wird eine wesentliche Verbesserung dadurch erzielt, daß als Aufbaustoff für die gasabgebenden Schaltkammerwandungen Isoliermaterialien dienen, die aus Schwefel bestehen oder einen mehr oder weniger großen Anteil j von Schwefel besitzen. Vor allem kommt hierfür Gummi, insbesondere Hartgummi, in Betracht.According to the invention, a significant improvement is achieved in that as a builder for the gas-emitting switching chamber walls are used as insulating materials made of sulfur or have a more or less large proportion j of sulfur. First of all, this comes about Rubber, especially hard rubber, are considered.

Diese Stoffe haben den Vorteil, daß sie unter der Einwirkung des Lichtbogens verdampfen, ohne Rückstände zu hinterlassen. Infolgedessen bleibt dauernd eine gute Oberflächenisolation erhalten. Die entwickelten Gase und Dämpfe schützen das Isolationsmaterial im übrigen nach dem bekannten Leidenfrostschen Phänomen vor zu starker Verdampfung, so daß bei Berührung mit einer größeren Anzahl schwerer Kurzschlußlichtbögen eines Hochleistungsschalters nur eine verhältnismäßig geringe Materialabnutzung stattfindet. HinzuThese substances have the advantage that they evaporate under the action of the arc without Leaving residue behind. As a result, a good surface insulation is permanently retained. The gases and vapors developed protect the insulation material according to the well-known methods Leidenfrost phenomenon from excessive evaporation, so that when in contact with a larger The number of severe short-circuit arcs in a high-performance switch is only proportionate low material wear takes place. In addition

kommt noch, daß diese Materialien mechanisch genügend fest und auch witterungsbeständig sind.still comes that these materials are mechanically sufficient are solid and weatherproof.
