Abstract
Lichtbogenlöschkammer eines aus zwei Gehäusehälften (1; 2) zusammengesetzten Leitungsschutzschalters mit aus mehreren Löschblechen (5.1) zusammengesetzter Funkenkammer und hinter dieser den Schaltkontakten gegenüberliegend angeordneten und an dem Gehäuse angeformten Wänden (1.1; 2.1) mit Öffnungen zum Austritt des Gasstromes und Verhinderung einer Rückzündung. Die an die Gehäusehälften (1; 2) angeformten sich gegenüberstehenden Wandteile (1.1; 2.1) sind an der Fügestelle (1.2; 2.2) stufenförmig ausgebildet und die Stufen (1.3; 2.3) so an den Gehäusehälften (1; 2) versetzt, daß Öffnungen (3) freibleiben.Arc extinguishing chamber of a line circuit breaker composed of two housing halves (1; 2) with a spark chamber composed of several arcing plates (5.1) and, behind this, walls (1.1; 2.1) arranged opposite the switching contacts and integrally formed on the housing with openings for the gas flow to exit and prevention of reignition. The opposing wall parts (1.1; 2.1) formed on the housing halves (1; 2) are step-shaped at the joint (1.2; 2.2) and the steps (1.3; 2.3) are offset on the housing halves (1; 2) in such a way that openings (3) remain free.

Die Erfindung betrifft eine Lichtbogenlöschkammer für Leitungsschutzschalter gemäß dem Oberbegriff des Schutzanspruchs 1.The invention relates to an arc extinguishing chamber for circuit breakers according to the preamble of Protection claim 1.
Bekannt ist eine Ausführung (DE-PS 12 38 538), bei der die Öffnungen der unmittelbar hinter der Funkenkammer angeordneten und an den Gehäusehälften angeformten Wand von Nocken gebildet werden, die jeweils hinter jedem Löschblech anHegen.An embodiment is known (DE-PS 12 38 538) in which the openings of the immediately behind the spark chamber arranged and formed on the housing halves wall of cams, each behind each extinguishing plate.
Weiterhin ist eine Ausführung (DE-OS 29 49 012) bekannt, bei der die hinter der Funkenkammer angeordneten und an die Gehäusehälften angeformten Wände Schlitze aufweisen, die gegeneinander versetzt angeordnet sind und die Dicke dieser Wände größer als die Schlitzbreite ist. Beim Bekannten liegen die Öffnungen unmittelbar an den Löschblechzwischenräurnen an.Furthermore, an embodiment (DE-OS 29 49 012) is known, in which the walls arranged behind the spark chamber and molded onto the housing halves Have slots which are offset from one another and the thickness of these walls is greater than that Slot width is. In the case of friends, the openings are located directly on the quenching plate intermediate grooves.
Nachteilig bei diesen bekannten Ausführungen ist, daß die angeformten Nocken sowie die mit Schlitzen versehenen Wände je nach Nockenlänge bzw. Schlitztiefe bruchanfällig sind, insbesondere beim Entformen sowie beim Entgraten und Lagern der Gehäusehälften.The disadvantage of these known designs is that the molded-on cams and those with slots provided walls are prone to breakage depending on the cam length or slot depth, especially when demolding as well as when deburring and storing the housing halves.
Aufgabe der Erfindung ist, die Gehäusehälften so auszubilden, daß diese bei der Fertigung und Weiterverarbeitung bruchunabfällig sind.The object of the invention is to design the housing halves so that they can be used during manufacture and further processing are not breakable.
Diese Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Anspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing part of claim 1.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, die Stufen so anzuordnen, daß die durch diese gebildeten Öffnungen unmittelbar an den LöschblechzwischenräuTien anliegen.In a further embodiment of the invention it is proposed to arrange the steps so that the through this formed openings directly at the extinguishing sheet metal spaces issue.
Ein Ausführungsbeispiel der Erfindung wird an Hand der Abbildungen erläutert. Es zeigtAn embodiment of the invention is explained with reference to the figures. It shows
A b b. 1 den Leitungsschutzschalter in Seitenansicht in Blickrichtung auf die Gehäusehälfte 2, deren Wandung im Bereich der Lichtbogenlöschkammer ausgebrochen dargestellt ist.A b b. 1 the miniature circuit breaker in side view in the direction of view of the housing half 2, the wall is shown broken away in the area of the arc extinguishing chamber.
Im ausgebrochenen Bereich ist die dahinterliegende Gehäusehälfte 1 dargestellt mit eingelegter Funkenkammer, bestehend aus distanziert angeordneten Löschblechen 5.1 zur Bildung von Löschblechzwischenräumen 5.2, durch die die Schaltgase zu den öffnungen 3 strömen und durch die Auslaßöffnungen 4 aus dem Leitungsschutzschalter austreten.In the broken-out area, the housing half 1 behind it is shown with an inserted spark chamber, consisting of extinguishing plates 5.1 arranged at a distance to create spaces between the extinguishing plates 5.2, through which the switching gases flow to the openings 3 and through the outlet openings 4 from the circuit breaker step out.
