Abstract
Description
Die Erfindung betrifft ein elektrisches Installationsgerät, insbesondere einen Leitungsschutzschalter, gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electrical installation device, in particular a circuit breaker, according to the preamble of claim 1.
Solche Installationsschaltgeräte dienen dazu, einen Überstrom oder einen Kurzschlußstrom abzuschalten. Zu diesem Zweck sind den Kontaktstücken Lichtbogenlöschbleche zugeordnet, in die bei einem Ausschaltvorgang der zwischen dem feststehenden und dem beweglichen Kontaktstück erzeugte Lichtbogen zu seiner Löschung hineinläuft.Installation switchgear of this type serves for an overcurrent or a short-circuit current switch off. For this purpose, the contact pieces are arcing plates assigned, in the case of a switch-off between the fixed and arcing generated in the movable contact piece runs to its quenching.
Wenn man seitlich an dem Lichtbogenentstehungsbereich eine stromdurchflossene Schleife anbringt, dann erzeugt man hierdurch ein ringförmiges, elektromagnetisches Feld, das eine verdrängende Wirkung auf das elektrische Feld des Schaltlichtbogens erzeugt und seine Wanderbewegung auf den den Kontaktstücken zugeordneten Lichtbogenlaufschienen beschleunigt.If you have a current flowing through the side of the arcing area Attaches a loop, then this creates an annular, electromagnetic Field that has a displacing effect on the electrical field of the switching arc generated and its traveling movement on the arc tracks assigned to the contact pieces accelerates.
Aufgabe der Erfindung ist es, das ringförmige elektromagnetische Feld, also das Blasfeld, zu verstärken und zu konzentrieren. The object of the invention is to define the ring-shaped electromagnetic field, that is to say the blowing field, to reinforce and concentrate.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.
Eine weitere, die Wirkungsweise der Maßnahmen gemäß Anspruch 1 verbessernde Ausgestaltung ist dem Anspruch 2 zu entnehmen.Another, the operation of the measures according to claim 1 improving Configuration can be found in claim 2.
Erfindungsgemäß also ist entweder auf einer Seite des Lichtbogenentstehungsbereiches oder auf beiden jeweils eine Isolierplatte angeordnet, die den Lichtbogenentstehungsbereich beidseitig begrenzt; hinter den isolierenden Platten befindet sich jeweils eine Eisenplatte, wobei diejenige Eisenplatte, die sich auf der Seite der Schleife befindet, innerhalb der Schleife angeordnet ist bzw. die Schleife das Eisenblech an seinem Außenumfang wenigstens teilweise umgibt.According to the invention, therefore, is either on one side of the arcing area or an insulating plate is arranged on each of them, which defines the arcing area limited on both sides; is located behind the insulating plates an iron plate, the iron plate that is on the side of the loop, is arranged within the loop or the loop the iron sheet on his At least partially surrounds the outer circumference.
Diese Anordnung erzeugt eine schnellere Wanderbewegung des Lichtbogens in Richtung Löschkammer, was eine deutliche Verbesserung der Kurzschlußstrombegrenzung zur Folge hat, so daß sich auch eine Verbesserung des Leitungsschutzes und der Selektivität ergibt.This arrangement creates a faster traveling movement of the arc in the direction Quenching chamber, which is a significant improvement in short-circuit current limitation has the consequence that there is also an improvement in line protection and selectivity results.
Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung näher erläutert und beschrieben werden.Using the drawing, in which an embodiment of the invention is shown, the invention and further advantageous refinements and improvements the invention are explained and described in more detail.

Die Fig. 1 zeigt den Lichtbogenentstehungsbereich eines Leitungsschutzschalters, in
dem sich ein an einer Lichtbogenleitschiene 10 angebrachtes festes Kontaktstück 11
sowie ein bewegliches Kontaktstück 12 befinden, welches an einem um eine Achse 13
schwenkbaren Kontakthebel 14 angebracht ist. Fig. 1 shows the arcing area of a circuit breaker, in
which is a fixed
Dem Lichtbogenentstehungsbereich ist eine weitere Lichtbogenleitschiene 15 zugeordnet,
die beidseitig ein aus mehreren Lichtbogenlösehblechen 16 bestehendes Lichtbogenlöschblechpaket
17 begrenzen.A further
Auf einer Seite, also bei der Ansicht gemäß Fig. 1 hinter dem Lichtbogenentstehungsbereich
befindet sich eine Schleife 18, die im stromdurchflossenen Zustand ein elektromagnetisches
Feld erzeugt, welches den zwischen dem feststehenden kontaktstück
11 und dem beweglichen Kontaktstück 12 entstehenden Lichtbogen 19 in das Lichtbogenlöschblechpaket
17 antreibt.On one side, ie in the view according to FIG. 1, behind the area where the arc is formed
there is a
Die Fig. 2 zeigt die Anordnung gemäß Schnittlinie II-II der Fig. 1. Beidseitig zu dem
Lichtbogenentstehungsbereich 20 befinden sich zwei Isolierstoffplatten 21 und 22 und
außerhalb der Isolierstoffplatte 22 befindet sich die Schleife 18. Innerhalb der Schleife
18, also praktisch in einer Ebene damit, ist eine erste Eisenplatte 23 vorgesehen, der
eine zweite Eisenplatte 24 auf der entgegengesetzten Seite, außerhalb der Isolierstoffplatte
21, entspricht.FIG. 2 shows the arrangement according to section line II-II of FIG. 1. On both sides of the
Arcing
Durch diese Anordnung wird das durch die Schleife erzeugte magnetische Blasfeld verstärkt und konzentriert und somit der Lichtbogen beschleunigt, so daß er schneller in das Lichtbogenlöschblechpaket einläuft und demgemäß die Qualität des Leitungsschutzes verbessert wird.With this arrangement, the magnetic blowing field generated by the loop amplified and concentrated and thus accelerates the arc so that it enters faster the arc-quenching plate package comes in and accordingly the quality of the line protection is improved.
