Abstract
Description
Die Erfindung betrifft ein elektrisches Installationsgerät, insbesondere einen Leitungs schutzschalter, gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electrical installation device, in particular a line Circuit breaker, according to the preamble of claim 1.
Solche Installationsschaltgeräte dienen dazu, einen Überstrom oder einen Kurzschluß strom 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.Such installation switching devices are used to prevent an overcurrent or a short circuit turn off power. 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 Licht bogenlaufschienen 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 generates and its traveling movement on the light assigned to the contact pieces curved running tracks accelerated.
Aufgabe der Erfindung ist es, das ringförmige elektromagnetische Feld, also das Blas feld, zu verstärken und zu konzentrieren. The object of the invention is the annular electromagnetic field, ie the blowing field, 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 Lichtbogenentstehungsberei ches oder auf beiden jeweils eine Isolierplatte angeordnet, die den Lichtbogenentste hungsbereich beidseitig begrenzt; hinter den isolierenden Platten befindet sich jeweils eine Eisenplatte, wobei diejenige Eisenplatte, die sich auf der Seite der Schleife befin det, innerhalb der Schleife angeordnet ist bzw. die Schleife das Eisenblech an seinem Außenumfang wenigstens teilweise umgibt.According to the invention is either on one side of the arcing area ches or an insulating plate is arranged on both, which arises the arc 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 det, 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 Rich tung Löschkammer, was eine deutliche Verbesserung der Kurzschlußstrombegrenzung zur Folge hat, so daß sich auch eine Verbesserung des Leitungsschutzes und der Se lektivität ergibt.This arrangement creates a faster traveling movement of the arc in Rich extinguishing chamber, which is a significant improvement in short-circuit current limitation has the consequence that there is also an improvement in line protection and Se 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.

Fig. 1 eine Schnittansicht eines Lichtbogenentstehungsbereiches gemäß Schnittli nie I-I der Fig. 2, und Fig. 1 is a sectional view of an arc formation area according to section II never of Fig. 2, and
Fig. 2 eine Schnittansicht gemäß Schnittlinie II-II der Fig. 1. Fig. 2 is a sectional view according to section line II-II in FIG. 1.
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, weiches an einem um eine Achse 13 schwenkbaren Kontakthebel 14 angebracht ist. Fig. 1 shows a mounted on an arc guide rail 10 fixed contact piece 11 and a movable contact piece are in the 12, soft is mounted on a pivotable about an axis 13 contact lever 14 to the arc generating area of a circuit breaker.
Dem Lichtbogenentstehungsbereich ist eine weitere Lichtbogenleitschiene 15 zugeord net, die beidseitig ein aus mehreren Lichtbogenlöschblechen 16 bestehendes Lichtbo genlöschblechpaket 17 begrenzen.A further arc guiding rail 15 is assigned to the arcing area, and on both sides it delimits an arcing plate packet 17 consisting of a plurality of arc extinguishing plates 16 .
Auf einer Seite, also bei der Ansicht gemäß Fig. 1 hinter dem Lichtbogenentstehungs bereich befindet sich eine Schleife 18, die im stromdurchflossenen Zustand ein elek tromagnetisches Feld erzeugt, welches den zwischen dem feststehenden Kontaktstück 11 und dem beweglichen Kontaktstück 12 entstehenden Lichtbogen 19 in das Lichtbo genlöschblechpaket 17 antreibt.On one side, that is, in the view according to FIG. 1 behind the arcing area is a loop 18 which, in the current-carrying state, generates an electromagnetic field which generates the arc 19 that arises between the fixed contact piece 11 and the movable contact piece 12 in the arc genlöschblechpaket 17 drives.
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 Isolierstoff platte 21, entspricht. FIG. 2 shows the arrangement according to section line II-II of FIG. 1. There are two insulating material plates 21 and 22 on both sides of the arcing area 20 and outside of the insulating material plate 22 is the loop 18 . Within the loop 18 , so practically in one plane with it, a first iron plate 23 is provided, which corresponds to a second iron plate 24 on the opposite side, outside the insulating plate 21 .
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 Leitungs schutzes 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.
