Abstract

Der Werkstoff enthält eine Isolierstoffmatrix und einen in die Matrix eingebetteten Füllstoff und zeichnet sich durch eine zeilenförmige Struktur aus. Der überwiegende Teil der Zellen ist mit einem lichtbogenlöschende Eigenschaften aufweisenden Material gefüllt oder enthält ein Material, welches bei Lichtbogeneinwirkung Lichtbogenlöschgas bildet.The material contains an insulating material matrix and one in the Embedded filler and is characterized by a line structure. The majority of the cells is with an arc extinguishing properties Material filled or contains a material that Arc exposure forms arc quenching gas.

Zur Verbesserung der Schaltleistung kann ein solcher Werkstoff mit Vorteil in einem Druckgasschalter eingesetzt werden, bei dem der Schaltlichtbogen (11) mit Löschgas beblasen wird. Hierbei wird der Werkstoff bevorzugt an löschgasführenden Stellen angeordnet, an denen der Werkstoff der Strahlung des Lichtbogens (11) und der thermischen Wirkung von Lichtbogengasen ausgesetzt ist.

Figure 00000001
To improve the switching performance, such a material can advantageously be used in a compressed gas switch in which the switching arc (11) is blown with extinguishing gas. In this case, the material is preferably arranged at points carrying extinguishing gas at which the material is exposed to the radiation from the arc (11) and the thermal effect of arc gases.
