Description
Es ist bekannt, bei elektrischen Schaltapparaten für höhere Spannungen nahe den Schaltkontakten feuerfeste Kammern vorzusehen, in denen der Öffnungsfunken zum Erlöschen gebracht wird. Um diese Kammern möglichst klein halten zu können und ein sicheres Erlöschen des Funkens zu gewährleisten, hat man die Kammern mit Zwischenwänden versehen, die dazu dienen, den Funken zu führen, zu verlängern und zu kühlen. Die Zwischenwände können sowohl parallel als auch quer zur Funkenrichtung gestellt sein. Bei der ersteren Anordnung wird der Funken vorzugsweise geführt und daher regelmäßig,It is known in electrical switchgear for higher voltages near the switch contacts to provide fireproof chambers in which the opening spark is extinguished. Around these chambers if possible to be able to keep it small and to ensure that the spark is safely extinguished the chambers are provided with partition walls that serve to guide the spark, to lengthen and cool. The partition walls can be placed both parallel and transversely to the spark direction. at in the former arrangement the spark is preferably guided and therefore regular,
während die letztere Anordnung eine wellenförmige Ausbildung und dementsprechend vor allem eine Verlängerung und rasche Kühlung des Funkens verursacht, so daß man mit einer kleineren Kammer auskommt.while the latter arrangement has an undulating configuration and accordingly mainly caused a lengthening and rapid cooling of the spark, so that one with get by with a smaller chamber.
Nach der Erfindung sind die Vorteile beider Systeme vereinigt, indem an Stelle von durchgehenden Querwänden Rippen angeordnet sind, welche abwechselnd an beiden Wänden der Funkenkammer ihren Anfang nehmen, aber nicht bis zur gegenüberliegenden Wand heranreichen. In der Zeichnung sind zwei Ausführungsbeispiele für die Erfindung dargestellt, und zwar im Längsschnitt quer zum Lichtbogen (Abb. 1), im Längsschnitt inAccording to the invention, the advantages of both systems are combined by instead of continuous transverse walls ribs are arranged, which alternate on both walls start of the spark chamber, but not reach the opposite wall. In the drawing are two embodiments of the invention shown, in longitudinal section transversely to the arc (Fig. 1), in longitudinal section in

sehen denen der Öffnungslichtbogen entsteht; sie sind an der tiefsten Stelle der aus den beiden parallelen Wänden b und den schmalen, schräg stehenden Querwänden c gebildeten Funkenkammer angebracht, die sich in bekannter Weise nach oben erweitert. Im Innern der Kammer befinden sich die isolierenden Querrippen d, die abwechselnd an beiden Längswänden b befestigt sind und gemäß Abb. 3 bis gegen die Mitte der Funkenkammer, gemäß Abb. 4 über die Mitte derselben hinaus in die Funkenkammer hineinragen. Sie stehen in fächerartiger Anordnung und werden daher auch als Funkenfächer bezeichnet.see where the opening arc occurs; they are attached to the lowest point of the spark chamber formed from the two parallel walls b and the narrow, inclined transverse walls c , which expands upwards in a known manner. Inside the chamber are the insulating transverse ribs d, which are alternately attached to both longitudinal walls b and protrude towards the center of the spark chamber as shown in Fig. 3 and beyond the center of the spark chamber as shown in Fig. 4. They are in a fan-like arrangement and are therefore also referred to as spark fans.
