At a certain length of the to be bridged by the arcs 11 air gap these jump to the
Löschblechen 9 der Lichtbogenlöschkammern 7, 8 über. Es hat sich dabei gezeigt, dass die zu diesem Zeitpunkt bestehenden Lichtbögen 11 eine erstaunliche Stabilität aufweisen, und es sein kann, dass diese Lichtbögen 11 an den betreffenden Löschblechen 9, an denen sie Kontaktieren, bestehen bleiben, bis es zur thermischen Zerstörung des Extinguishing plates 9 of the arc extinguishing chambers 7, 8 via. It has been found that the present at this time arcs 11 have an astonishing stability, and it may be that these arcs 11 at the respective quenching plates 9, where they contact, remain, until it is for the thermal destruction of the
Gleichstromschaltgeräts 1 kommt. Dieses Problem ist in der Wechselstromtechnik in der Art nicht bekannt, da es aufgrund der ständig erfolgenden Nulldurchgänge der anliegenden Spannung schnell zu einem Verlöschen auftretender Wechselstromlichtbögen kommt. DC switching device 1 comes. This problem is not known in the AC technique in the way it comes to quickly extinguishing occurring AC arcs due to the constant zero crossings of the applied voltage.
Es ist daher vorgesehen, dass das Gleichstromschaltgerät 1 eine Magnetanordnung 10 aufweist, welche derart ausgebildet ist, dass auf die - durch einen Schaltvorgang verursachten - Lichtbögen 11 , in der ersten Lichtbogenlöschkammer 7 und in der zweiten It is therefore provided that the DC switching device 1 has a magnet assembly 10 which is designed such that on the - caused by a switching operation - arcs 11, in the first arc quenching chamber 7 and in the second
Lichtbogenlöschkammer 8, jeweils eine Lorentzkraft 12 in Richtung der Löschbleche 9 wirkt. Daher, dass auf die jeweils auftretenden Lichtbögen 11 eine Lorentzkraft 12 wirkt, welche den Lichtbogen 11 in der ersten Lichtbogenlöschkammer 7 und den Lichtbogen 11 in der zweiten Lichtbogenlöschkammer 8 jeweils hin zu den Löschblechen 9 beschleunigt und die Lichtbögen 11 förmlich an die Löschbleche 9 bzw. in die Zwischenräume zwischen den Löschblechen 9 drückt. Da es sich bei einem Lichtbogen 11 um bewegte elektrische Ladungen handelt, wirken auf diesen in einem Magnetfeld auch entsprechende Kräfte. Mit anderen Worten ist vorgesehen, dass die Magnetanordnung 10 ein B-Feld erzeugt, welches im Bereich der Lichtbögen 11 normal zur Längserstreckung der Lichtbögen 11 ist. Dies ist etwa in Fig. 3, welche eine besonders bevorzugte Ausführungsform der gegenständlichen Erfindung zeigt dargestellt. Dabei sind in Fig. 3 die beiden Lichtbögen 11 als Vektoren, welche projizierende auf die Schnittebene angeordnet sind, dargestellt, sowie die jeweils wirkenden Lorentzkräfte 12 bzw. F. Die Bereiche in denen Lichtbögen 11 auftreten sowie deren Richtung, sind durch die Konstruktion des Gleichstromschaltgerät 1 vorgegeben bzw. können durch die Konstruktion des Gleichstromschaltgerät 1 beeinfiusst werden. Arc quenching chamber 8, each a Lorentz force 12 in the direction of the quenching plates 9 acts. Therefore, that acts on the respective occurring arcs 11 a Lorentz force 12 which accelerates the arc 11 in the first arc quenching chamber 7 and the arc 11 in the second arc quenching chamber 8 toward the quenching plates 9 and the arcs 11 formally to the quenching plates 9 and in the spaces between the quenching plates 9 presses. Since an electric arc 11 involves moving electric charges, corresponding forces also act on them in a magnetic field. In other words, it is provided that the magnet arrangement 10 generates a B-field which is normal to the longitudinal extension of the arcs 11 in the region of the arcs 11. This is shown approximately in FIG. 3, which shows a particularly preferred embodiment of the subject invention. 3, the two arcs 11 are shown as vectors, which are arranged projecting on the cutting plane, as well as the respectively acting Lorentz forces 12 and F. The areas in which arcing 11 occur and their direction, are by the construction of the DC switching device 1 or can be influenced by the construction of the DC switching device 1.

Daher eine der beiden Flächen ist vollflächig ein Südpol und die andere Fläche ein Nordpol. Bevorzugt handelt es sich bei den verwendeten Magneten jeweils um Permanentmagneten. It has proven to be advantageous in this case to carry out the first magnet 13 and the second magnet 14 in each case as flat or sheet-like magnets, with a very small thickness, whose poles are respectively formed on the cover surfaces. Therefore, one of the two surfaces is a south pole and the other surface is a north pole. Preferably, the magnets used are each permanent magnets.
Als besonders vorteilhaft hat sich die Anordnung des ersten Magneten 13 seitlich an der ersten Lichtbogenlöschkammer 7 sowie des zweiten Magneten 14 seitlich an der zweiten Lichtbogenlöschkammer 8 erwiesen, wodurch eine sehr gleichmäßige B-Feld- Verteilung in den beiden Lichtbogenlöschkammem 7, 8 erreicht werden kann. To be particularly advantageous, the arrangement of the first magnet 13 has laterally on the first arc quenching chamber 7 and the second magnet 14 laterally to the second arc quenching chamber 8 proved, creating a very uniform B field distribution in the two arc extinguishing chambers 7, 8 can be achieved.
Es hat sich als besonders vorteilhaft, insbesondere hinsichtlich der Fertigung erwiesen, dass der erste Magnet 13 und der zweite Magnet 14 zwischen der ersten Lichtbogenlöschkammer 7 und der zweiten Lichtbogenlöschkammer 8 angeordnet sind. Die beiden Magnete 13, 14 sind dabei in einem Steg 15 zwischen den beiden Lichtbogenlöschkammern 7, 8 angeordnet, wie dies in Fig. 3 dargestellt ist. In Fig. 2 ist der derart gebildete Steg 15 deutlich zu erkennen. Durch diesen Steg 15 ergibt sich zudem ein Abstand zwischen den beiden It has proved to be particularly advantageous, in particular with regard to production, that the first magnet 13 and the second magnet 14 are arranged between the first arc quenching chamber 7 and the second arc quenching chamber 8. The two magnets 13, 14 are arranged in a web 15 between the two arc extinguishing chambers 7, 8, as shown in Fig. 3. In Fig. 2, the web 15 thus formed is clearly visible.
