Abstract

An electrical line protection circuit breaker having a stationary contact element and a moving contact element and having an arc splitter stack which is allocated to the contact point and adjacent to which there is a switching gas dissipation channel, which is divided into an expansion chamber 2A, which chamber is adjacent to the arc splitter stack and downstream from which there are, in the specified sequence, flow channels 2B, an expansion chamber 2C and outlet channels 2D. <IMAGE>

Description

Die Erfindung betrifft einen elektrischen Leitungsschutzschalter gemäß dem Oberbegriff des Schutzanspruches 1.The invention relates to an electrical circuit breaker according to the preamble of protection claim 1 .

Bedingt durch die hohen Schaltleistungen, die derartige Lei­ tungsschutzschalter erfüllen müssen, erfordern die beim Schalten entstehenden Gase besondere Maßnahmen, um zu verhindern, daß diese beim Austritt die darüber bzw. darunter angeordneten Be­ triebsmittel nachteilig beeinflussen.Due to the high switching capacities, the Lei circuit breakers must be met when switching resulting gases special measures to prevent this the Be arranged above or below the outlet adversely affect propellants.

Bekannt ist durch die DE-AS 11 88 187, die Schaltgase über Nebenräume abzuleiten, wobei sich der Gasdruck ausgleichen kann und die Gase eine Abkühlung erfahren.Is known from DE-AS 11 88 187, the switching gases To derive secondary rooms, whereby the gas pressure can even out and the gases cool down.

In der CH-PS 3 84 686 ist eine ähnliche Anordnung beschrieben, bei der der Nebenraum jedoch als teilzylindrische Kammer ausge­ bildet ist, in der den Gasen eine Wirbelwirkung verliehen wird. Bei beiden Anordnungen erfolgt der Austritt der Schaltgase über eine düsenartige Austrittsöffnung.A similar arrangement is described in CH-PS 3 84 686, in which the adjoining room is out as a partially cylindrical chamber is formed in which the gases are given a vortex effect. In both arrangements, the switching gases exit via a nozzle-like outlet opening.

Aufgabe der Erfindung ist, den Schaltgaskanal so auszubilden, daß die Schaltgase abgekühlt und mit verhältnismäßig niedriger Geschwindigkeit in eine vorbestimmte Richtung gelenkt werden.The object of the invention is to design the switching gas channel in such a way that the switching gases are cooled and relatively low Speed can be steered in a predetermined direction.

Diese Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Schutzanspruches 1 gelöst.This object is achieved by the characterizing part of claim 1 .

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, die Schaltgase schräg zwischen der Klemmenseite und der Befesti­ gungsauflagenseite herauszulenken.In a further embodiment of the invention it is proposed that Switching gases diagonally between the terminal side and the fastening to guide out the support side.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Zeichnun­ gen erläutert: An embodiment of the invention is based on the drawing explained:  

Es zeigtIt shows

Fig. 1 die prinzipielle Ausgestaltung des Schaltgasableitkanals des Leitungsschutzschalters; Figure 1 shows the basic design of the Schaltgasablitkanals of the circuit breaker.

Fig. 2 eine besondere Ausgestaltung, bei der der Schaltgaskanal zum Teil an der Außenseite des Leitungsschutzschalterge­ häuses in Gestalt eines Absatzes ausgeformt ist, auf dem eine die Gehäusewand ergänzende Abdeckung aufliegt. Fig. 2 shows a special embodiment, in which the switching gas channel is partially formed on the outside of the circuit breaker housing in the form of a paragraph on which a cover complementing the housing wall rests.

Die im Innern des Leitungsschutzschalters 1 beim Schalten er­ zeugten Schaltgase strömen durch das Lichtbogenlöschpaket 4 in den Schaltgasableitkanal 2. Dieser Schaltgasableitkanal 2 be­ steht aus dem an das Lichtbogenlöschpaket 4 angrenzenden Expan­ sionsraum 2 A, den daran anschließenden den Strömungskanal ver­ engenden Strömungskanälen 28, denen sich wiederum ein Expan­ sionsraum 2 C anschließt, von dem aus die Schaltgase über die Auslaßkanäle 2 D in die umgebende Atmosphäre ausströmen.The inside of the circuit breaker 1 when switching, he generated switching gases flow through the arc quenching package 4 in the switching gas discharge channel 2 . This Schaltgasablitkanal 2 be from the adjacent to the arc extinguisher package 4 expansion chamber 2 A , the adjoining the flow channel ver narrowing flow channels 28 , which in turn is connected to an expansion chamber 2 C , from which the switching gases via the outlet channels 2 D into the surrounding Exude atmosphere.

Bei einer besonderen Ausgestaltung der Erfindung wird ein Teil des Schaltgasableitkanals 2 durch einen Absatz 1 D, der an der Gehäusewand 1 A ausgeformt ist, und einer die Gehäusewand 1 A er­ gänzenden Abdeckung 3 gebildet.In a special embodiment of the invention, part of the switching gas discharge duct 2 is formed by a shoulder 1 D , which is formed on the housing wall 1 A , and a cover 3 that complements the housing wall 1 A.

Die Auslaßkanäle 2 D sind jeweils so angeordnet, daß die Schalt­ gase schräg zwischen der Klemmenseite 1 B und der Befesti­ gungsauflageseite 1 C herausgelenkt werden.The outlet channels 2 D are each arranged so that the switching gases are directed diagonally between the terminal side 1 B and the fastening supply side 1 C out.
