Description
Kleinselbstschalter mit magnetischer Fun'kenlöschung, bei denen sich der an der Schaltvorrichtung angelenkte Kontakt senkrecht zur Achse der Blasspulee bewegt, haben in der Regel eine Funkenkammer, bei der der Kontakt zwischen den beiden senkrecht zur Spulenachse stehenden Kammerwänden geführt ist. Da aber die Leistung dieser Schalter neben Schaltgeschwindigkeit und Blaskraft der Magnetspule auch von der Größe der Funkenkammer abhängig ist, ist man bestrebt, die letztere möglichst groß auszuführen, um dem Lichtbogen Platz zur Ausdehnung und Abkühlung zu schaffen. Die Funkenkammer wird vielfach mit Kühlrippen versehen.Small circuit breakers with magnetic spark extinction, in which the contact hinged to the switching device perpendicular to the axis of the blowpole moves, usually have a spark chamber where contact between the two is guided perpendicular to the coil axis standing chamber walls. But there the performance this switch in addition to switching speed and blowing force of the solenoid coil also from the size of the spark chamber is dependent, one strives to use the latter as possible Make it large in order to create space for the arc to expand and cool down. The spark chamber is often provided with cooling fins.
Gemäß der Erfindung wird die in Richtung der Spulenachse verbreiterte Funkenkammer mit Kühlrippen versehen, von denen eine so ausgebildet ist, daß sie zur Führung des beweglichen Kontakts dient. Das hat den Vorteil, daß die Funkenkammer beliebig breit bis an die Außenwand des Schalters ausgeführt und dadurch die Schaltleistung erheblich erhöht werden kann.According to the invention, the widened in the direction of the coil axis Spark chamber provided with cooling fins, one of which is designed so that it serves to guide the moving contact. This has the advantage that the spark chamber Any width up to the outside wall of the switch and thus the switching capacity can be increased significantly.
Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung an einem Kleinselbstschalter in Schraubstöpselform.The figure shows an embodiment of the invention on one Small self-switch in screw plug shape.
In dem Gehäuse g (Abb. r und 2) befindet sich die Auslöse- und Blasspule nz, mit dem Auslöseanker n. Die Spule m ist durch die Wand u, von der Funkenkammer f getrennt, in welcher die Schaltkontakte h und i angebracht sind. Der bewegliche Kontakt h steht durch die Schaltstange s mit der nicht gezeichneten Schaltmechanik in Verbindung, an die er bei t angelenkt ist. Die Funkenkammer ist mit den Kühlrippen a, b, c, d und e versehen, die in Richtung der Bewegung des Kontakts 17 verlaufen. Die Kühlrippe c ist so breit, daß sie in einen Ausschnitt zc des Kontakts h reicht, wodurch dieser bei Aufundniedergehen in seiner Richtung gehalten und am Ausweichen aus seiner Bewegungsbahn verhindert ist. Je nach Führung der Schaltstange s in der Abschlußwand o und der Anlenkung der Schaltstange an der Schaltmechanik kann auf den Ausschnitt u in dem Kontakt h verzichtet «erden.In the housing g (Fig. R and 2) is the release and blow-out coil nz, with the release armature n. The coil m is separated by the wall u, from the spark chamber f, in which the switching contacts h and i are attached. The movable contact h is connected by the switching rod s to the switching mechanism, not shown, to which it is hinged at t. The spark chamber is provided with cooling fins a, b, c, d and e , which run in the direction of movement of the contact 17. The cooling rib c is so wide that it extends into a cutout zc of the contact h, as a result of which it is held in its direction when it goes up and down and is prevented from deviating from its path of movement. Depending on the guidance of the switching rod s in the end wall o and the articulation of the switching rod on the switching mechanism, the cutout u in the contact h can be dispensed with.
