Abstract
Description
Die Erfindung bezieht sich auf eine Lichtbogen-Löscheinrichtung für einen elektrischen Schalter mit mehreren parallel zueinander angeordneten Lichtbogen-Löschblechen und mit zumindest einem Teil aus gasendem Kunststoff.The The invention relates to an arc extinguishing device for one electrical switch with a plurality of mutually parallel arc-quenching plates and at least part of gassing plastic.
Die Erfindung bezieht sich weiterhin auf einen elektrischen Schalter mit einer derartigen Lichtbogen-Löscheinrichtung.The The invention further relates to an electrical switch with such an arc extinguishing device.
Der Einsatz von gasenden Kunststoffen in Lichtbogen-Löscheinrichtungen ist an sich bekannt. Diese „gasenden" Kunststoffe zeichnen sich dadurch aus, dass bei einer Wechselwirkung mit einem Schaltlichtbogen aus der Oberfläche der Kunststoffe gasförmige Zersetzungsprodukte freigesetzt werden. Die gasförmigen Zersetzungsprodukte, die auch unter der Bezeichnung „Hartgas" bekannt sind, führen zu einem Überdruck am Ort der Lichtbogenlöschung und zwingen den Lichtbogen damit schneller zum Erlöschen.Of the Use of gassing plastics in arc extinguishing systems is known per se. These "gassing" plastics draw characterized by the fact that when interacting with a switching arc from the surface the plastics gaseous Decomposition products are released. The gaseous decomposition products, which are also known by the name "hard gas", lead to an overpressure at the place of arc quenching and force the arc to extinguish faster.

mit den Merkmalen des Oberbegriffes des Patentanspruches 1 (
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der gasende Kunststoff glasfaserverstärkt ist. – Diese Glasfaserverstärkung wirkt selbst bei häufiger Wechselwirkung mit-Lichtbögen strukturerhaltend.These Task is inventively characterized solved, that the gassing plastic is glass fiber reinforced. - This glass fiber reinforcement works by itself at more frequent Interaction with arcs sustaining structure.
Eine bevorzugte Ausgestaltung der neuen Lichtbogen-Löscheinrichtung sieht vor, dass der gasende Kunststoff einen Zusatz aus rotem Phosphor zur Brandschutzoptimierung enthält. – So kann als gasender Kunststoff insbesondere das als Spritzgussmarke Ultramid® A3X2G7 bekannte Polyamid verwendet werden.A preferred embodiment of the new arc extinguishing device provides that the gassing plastic contains an addition of red phosphorus for fire protection optimization. - Sun can be used as a gassing plastic in particular that known as injection molding grade Ultramid ® A3X2G7 polyamide.
