Abstract

Es wird ein Installationsschaltgerät mit einer ein festes und ein bewegliches Kontaktstück (20, 19) aufweisenden Kontaktstellen beschrieben, mit einer Lichtbogenlöschkammeranordnung mit parallel zueinander gestapelten Lichtbogenlöschblechen und zwei Lichtbogenleitschienen (21, 22), die den Lichtbogen bei einer Schalthandlung zu den Löschblechen führen. Die Löschkammeranordnung ist aus zwei nebeneinander liegenden Löschblechpaketen (23, 24) gebildet. Es ist eine erste und eine zweite Zusatzleitschiene (25, 26) vorgesehen, von denen eine zum ersten Löschblechpaket und die andere zum zweiten Löschblechpaket geführt ist. Im kontaktstellennahen Bereich sind Zusatzleitschienen (25, 26) miteinander verbunden, so daß bei einer Ausschaltung der Lichtbogen in zwei Teillichtbögen aufgeteilt wird, von denen einer dem ersten Lichtbogenlöschblechpaket und der andere dem zweiten Lichtbogenlöschblechpaket zugeführt wird.

Figure 00000001
An installation switching device is described with a contact points having a fixed and a movable contact piece (20, 19), with an arc quenching chamber arrangement with arc quenching plates stacked parallel to one another and two arc guide rails (21, 22) which guide the arc to the quenching plates during a switching operation. The quenching chamber arrangement is formed from two quenching plate packs (23, 24) lying side by side. A first and a second additional guide rail (25, 26) are provided, one of which leads to the first quenching plate package and the other to the second quenching plate package. In the area close to the contact point, additional guide rails (25, 26) are connected to one another, so that when the arc is switched off, it is divided into two partial arcs, one of which is fed to the first arc quenching plate packet and the other to the second arc quenching plate packet.
