Abstract

An arc extinguishing chamber of a line circuit breaker composed of two housing halves (1; 2), having a spark chamber composed of a plurality of extinguishing plates (5.1) and, behind said chamber, walls (1.1; 2.1) which are arranged opposite the switch contacts, are integrally formed on the housing, and have openings for the outlet of the gas flow and to prevent arcing back. The mutually opposite wall parts (1.1; 2.1), which are integrally formed on the housing halves (1; 2), are constructed in a stepped manner at the joining point (1.2; 2.2) and the steps (1.3; 2.3) are offset on the housing halves (1; 2) such that openings (3) remain free. <IMAGE>

Description

Lichtbogenlöschkammer. Arc chamber.

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 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 anliegen.One embodiment is known (DE-PS 12 38 538) in which the openings the one arranged directly behind the spark chamber and molded onto the housing halves Wall are formed by cams, which rest behind each quenching plate.

Weiterhin ist eine Ausführung (DE-OS 29 49 012) hekannt, 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.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 that are offset from one another and the thickness of these Walls is larger than the slot width.

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 Cams as well as the walls provided with slots depending on the length of the cams or the depth of the slot are prone to breakage, especially during demolding, deburring and storage the housing halves.

Aufgabe der Erfindung ist, die Gehäusehälften so auszubilden, daß diese bei der Fertigung und Weiterverarbeitung bruchunanfällig sind.The object of the invention is to design the housing halves so that these are not susceptible to breakage during production and further processing.

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 solved.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, die Stufen so anzuordnen, daß die durch diese gebildeten Öffnungen unmittelbar an den Löschblechzwischenräumen anlegen.In a further embodiment of the invention, it is proposed that the stages to be arranged in such a way that the openings formed by these are directly adjacent to the spaces between the splitter plate invest.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Abbildungen erläutert: Es zeigt Abb. 1 den Leitungsschutzschalter in Seitenansicht in Blickrichtung auf die Gehäusehälfte 2, deren Wandung im Bereich der Lichtbogenlöschkammer ausgebrochen dargestellt ist.An embodiment of the invention is based on the figures explained: Fig. 1 shows the miniature circuit breaker in side view in the direction of view on the housing half 2, the wall of which has broken out in the area of the arc extinguishing chamber is shown.

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. The half of the housing behind is in the broken-out area 1 shown with inserted spark chamber, consisting of spaced Extinguishing plates 5.1 for the formation of extinguishing plate spaces 5.2 through which the switching gases to the openings 3 and flow through the outlet openings 4 from the circuit breaker step out.

Abb. 2 zeigt die Frontansicht des Leitungsschutzschalters mit Teilschnitt durch die Lichtbogenlöschkammer nach der in Abb. 1 eingezeichneten Schnittlinie. Darin sind die Kontur der Löschbleche 5.1 sowie die unmittelbar an die Löschblechzwischenräume 5.2 angrenzenden Öffnungen 3 und die Auslaßöffnungen 4 ersichtlich.Fig. 2 shows the front view of the miniature circuit breaker with partial section through the arc extinguishing chamber according to the section line shown in Fig. 1. This contains the contour of the quenching plates 5.1 as well as those directly on the spaces between the quenching plates 5.2 adjacent openings 3 and the outlet openings 4 can be seen.

Abb. 3 zeigt den Leitungsschutzschalter in der Seitenansicht auf die Lichtbogenlöschkammer mit Teilschnitt nach der in Abb. 1 eingezeichneten Schnittlinie, aus der die Stufen 1.3; 2.3 an der Fügestelle 1.2; 2.2 der Wandteile 1.1; 2.1 ersichtlich sind. Die Stufen 1.3; 2.3 an den einteilig an die Gehäusehälften 1; 2 angeformten Wandteile 1.1; 2.1 sind so zueinander versetzt, daß sich die Öffnungen 3 ergeben.Fig. 3 shows the miniature circuit breaker in a side view of the Arc extinguishing chamber with partial section according to the section line shown in Fig. 1, from which the stages 1.3; 2.3 at the joint 1.2; 2.2 of the wall parts 1.1; 2.1 can be seen are. The levels 1.3; 2.3 on the one-piece to the housing halves 1; 2 molded Wall parts 1.1; 2.1 are offset from one another in such a way that the openings 3 result.

In dieser Darstellung ist die Stufung vorzugsweise zur Funkenkammer diagonal verlaufend dargestellt. In this representation, the gradation is preferably to the spark chamber shown running diagonally.

Abb. 4 zeigt eine weitere Ausführungsmöglichkeit der stufenförmigen Anordnung der Wandteile 1.1; 2.1.Fig. 4 shows a further embodiment of the step-shaped Arrangement of the wall parts 1.1; 2.1.
