Definitions
- the invention relates to an electrical installation device with arc Vorschraum, Vorschplatten and current-limiting arc quenching device according to the preamble of claim 1.
- the invention can be used for example in circuit breakers and motor protection switches.
- Miniature circuit breakers and motor protection switches are used in the event of a fault to disconnect electrical lines that are loaded with high current overcurrents from the supply network.
- a fixed and a movable contact piece are provided in an arc Vorschraum, which are connected to the respective terminals.
- a switching arc which is deleted in a designated extinguishing device.
- the drawn arc commutes from the opened contact pieces on arc guide rails, and then subdivided into an arc splitter stack (Deion quenching chamber). There, a high arc voltage is generated to limit the current, so that the arc goes out.
- an arc extinguishing arrangement for an electrical switching device which comprises a quenching chamber (in which a switching action between a fixed and a movable contact piece is generated an arc) and a plurality of arc quenching arc splitter stack in which the arc is guided over guide rails.
- the invention has for its object to provide an electrical installation device with arc Vorschraum, Vorhuntplatten and current-limiting arc quenching, the high dielectric strength is maintained even after repeated triggering with the emergence of an arc.
- the two prechamber plates 8 mentioned above are formed from an insulating material (such as ceramic or plastic) and arranged on both broad sides of the arc prechamber space 7 such that a return flow channel is formed between the housing wall and the prechamber plate 8. Deflections redirect the gases flowing through these return flow channels back to the arc prechamber space 7.
- the prechamber plates 8 are geometrically arranged such that a return flow behind these prechamber plates is made possible only in the expansion area of the arc, whereby the arc 13 is accelerated in the direction of the arc quenching device 12.
- FIGS. 2, 3 and 4 show in detail three different embodiments of an antechamber plate.
- two outer slots 20, 22 and a central slot 21 are introduced in an overlapping manner into the prechamber plates 8 approximately parallel to the arc guide rail 16, this at least one slot transverse to the imaginary connection between the arc guide rails 14, 16 runs.
- the slots 20, 22 open directly in the edge regions of the prechamber plates.
- a narrow web 23 is formed between slot 20 and edge region and a narrow web 24 between slot 22 and edge region.
- only two slits 25, 26 introduced in an overlapping manner into the prechamber plates 8 are provided.
- edge-side webs can also be formed in this variant.
- the edge-side web 23 and 24 facilitates the assembly, because it is a tilting of the pre-chamber plate 8 effectively prevented during the fully automatic assembly of the switching device. If a creepage distance should develop after repeated occurrence of an arc over this web 23 or 24, the web melts (provided that a plastic material for the Vorschplatten 8 is used), whereby an elongated slot 20 or 22 is formed.

Leitungsschutzschalter und Motorschutzschalter dienen dazu, im Störungsfall elektrische Leitungen, die mit Überströmen hoher Stromstärke belastet sind, vom speisenden Netz zu trennen. Hierzu sind üblicherweise ein festes und ein bewegliches Kontaktstück in einem Lichtbogen-Vorkammerraum vorgesehen, die mit den jeweiligen Anschlussklemmen verbunden sind. Beim Öffnen des Schaltkontaktes, d. h. beim Abheben des beweglichen Kontaktstückes vom feststehenden Kontaktstück, entsteht ein Schaltlichtbogen, welcher in einer hierzu vorgesehenen Löscheinrichtung gelöscht wird. Der gezogene Lichtbogen kommutiert von den geöffneten Kontaktstücken auf Lichtbogenleitschienen, um sich anschließend in einem Lichtbogenlöschblechpaket (Deion-Löschkammer) zu unterteilen. Dort wird eine hohe Lichtbogenspannung zur Strombegrenzung erzeugt, so dass der Lichtbogen erlischt.Miniature circuit breakers and motor protection switches are used in the event of a fault to disconnect electrical lines that are loaded with high current overcurrents from the supply network. For this purpose, usually a fixed and a movable contact piece are provided in an arc Vorkammerraum, which are connected to the respective terminals. When opening the switching contact, ie when lifting the movable contact piece from the fixed contact piece, a switching arc, which is deleted in a designated extinguishing device. The drawn arc commutes from the opened contact pieces on arc guide rails, and then subdivided into an arc splitter stack (Deion quenching chamber). There, a high arc voltage is generated to limit the current, so that the arc goes out.

Bei Entstehung eines Lichtbogens 13 im Lichtbogen-Vorkammerraum 7 besteht das Risiko, dass die Vorkammerplatten 8 zum Teil verrußen. Je nach Anzahl der erfolgen Auslösungen des Schaltgerätes inklusive Entstehung eines Lichtbogens führt dies dazu, dass sich Kriechstrecken auf den Vorkammerplatten 8 zwischen den die Vorkammerplatten 8 kontaktierenden Lichtbogenleitschienen 14, 16 ausbilden und sich die Isolationseigenschaften der Vorkammerplatten 8 verschlechtern. Durch die vorgeschlagenen Schlitze 20, 21, 22, 25, 26 ergibt sich eine Verlängerung dieser Kriechstrecken, da zusätzliche Luftstrecken eingeführt werden. Insgesamt ergibt sich eine höhere Spannungsfestigkeit des Schaltgerätes.When an
Der randseitige Steg 23 bzw. 24 erleichtert die Montage, denn es wird ein Verkanten der Vorkammerplatte 8 während der vollautomatischen Montage des Schaltgerätes wirksam verhindert. Falls sich eine Kriechstrecke nach mehrmaligem Auftreten eines Lichtbogens über diesen Steg 23 bzw. 24 ausbilden sollte, schmilzt der Steg durch (vorausgesetzt, es wird ein Kunststoffmaterial für die Vorkammerplatten 8 eingesetzt), wodurch sich ein verlängerter Schlitz 20 bzw. 22 ausbildet.The edge-
