Description

DEUTSCHESGERMAN

Gegenstand der Erfindung ist eine magnetische Blaseinrichtung für elektrische Schalter, insbesondere für Selbstschalter. Derartige Blaseinrichtungen bestehen im allgemeinen aus einer von dem abzuschaltenden Strom durchflossenen Blasspule, die mit Polblechen versehen sind, die das magnetische Feld zu den Kontakten bzw. bis zur Lichtbogenkammer übertragen. Erfindungsgemäß ist der Magnetkern der Spule betriebsmäßig lösbar unter Verwendung eines Federbügels mit seinen Polblechen, die ihrerseits reibungsschlüssig mit den eigentlichen Blasblechen zusammenwirken, verbunden. Durch diese Anordnung besteht eine leicht ein- und auszubauende Einrichtung. Insbesondere für Bauserien, bei denen unter Umständen in gleiche Schaltertypen unterschiedlich starke Blasspulen eingebaut werden sollen, ist die Anordnung schon deshalb besonders vorteilhaft, weil auch nach der Montage die Blasspule verhältnismäßig leicht ausgebaut bzw. ausgewechselt werden kann.The invention relates to a magnetic blowing device for electrical switches, in particular for self switch. Such blowers generally consist of one of the ones to be shut down Current-flowing blower coils, which are provided with pole plates, which the magnetic field to to the contacts or to the arc chamber. According to the invention, the magnetic core is the Coil operatively detachable using a spring clip with its pole plates, which in turn co-operate frictionally with the actual blower plates, connected. Through this arrangement consists of a facility that is easy to install and remove. In particular for series, where under certain circumstances Blowing coils of different strengths are to be installed in the same switch types, is the arrangement Particularly advantageous because the blower coil is relatively easy to remove even after assembly or can be exchanged.

In der Zeichnung ist in drei Ansichten (Fig. 1 bis 3) eine Einrichtung nach der Erfindung dargestellt. Die Blasspule 1, die aus einem hochkant gewickelten Leiterband besteht, ist auf dem Spulenkörper 2 aufgebracht. Die Spule wird in bekannter Weise von einem Magnetkern 3 durchsetzt. Unmittelbar an dem Spulenkörper sind die Polbleche 4 und 5 angeordnet, die mit einer kreisrunden Bohrung für den Kern 3 versehen sind, daß sie an diesem einen gewissen Halt haben. Der Kern 3 hat zur Halterung dieser Polbleche eine Ringnut 7, in die sich ein haarnadelförmiger Federbügel 6 einlegt und die gesamte Blasspule mit Polblechen zusammenhält. Der Federbügel 6 selbst ist in einem beliebigen Gehäuseteil 8 des Schalters eingespannt. Um den Polblechen einen guten Sitz zu geben, können an dem Gehäuse 2 Vorsprünge 9 vorgesehen sein, an dem sich diese abstützen. Die Polbleche 4 und 5 liegen kraftschlüssig an den Blasblechen 10 an, die selbst wieder auf der Außenseite der meist aus Keramik gefertigten Löschkammerwandungen 11 befestigt sind. In Fig. 1 sind ferner noch die Lage der Kontakte 12 und die Löschbleche 13 angedeutet.In the drawing, a device according to the invention is shown in three views (Fig. 1 to 3). The blowing coil 1, which consists of an edgewise wound conductor strip, is applied to the bobbin 2. A magnetic core 3 passes through the coil in a known manner. The pole plates 4 and 5 are arranged directly on the coil body and are provided with a circular bore for the core 3 so that they have a certain hold on this. To hold these pole sheets, the core 3 has an annular groove 7 into which a hairpin-shaped spring clip 6 is inserted and holds the entire blow coil together with the pole sheets. The spring clip 6 itself is clamped in any housing part 8 of the switch. In order to give the pole plates a good fit, projections 9 can be provided on the housing 2, on which they are supported. The pole plates 4 and 5 rest in a non-positive manner on the blower plates 10, which are themselves fastened again on the outside of the extinguishing chamber walls 11, which are usually made of ceramic. In Fig. 1, the position of the contacts 12 and the quenching plates 13 are also indicated.
