KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In der Patentschrift 269613 ist ein Blaselektromagnet für die Abreißelektroden elektrischer Schalter beschrieben, bei welchem sich die Elektroden in ihrer Form der Blasspule vollkommen anschmiegen. Bei kreiszylindrischer Blasspule entsprechend der Zeichnung der genannten Patentschrift legen sich beispielsweise die Elektroden konzentrisch um die Spule herum, wobei die Stromrichtung in den Elektroden derjenigen in der Spule entgegengesetzt ist.In the patent specification 269613 is a blow solenoid for the tear-off electrodes electrical switch is described, in which the electrodes are in their shape of the blowing coil snuggle up completely. With a circular-cylindrical blow coil according to the drawing of the patent mentioned, for example, the electrodes are concentrically folded around the coil, the direction of the current in the electrodes being opposite to that in the coil is.
Nach der Zeichnung jener Patentschrift besitzen ferner die Abreißelektroden beide oder nur eine an ihrem Fußende Drehpunkte, um welche sie bei Betätigung des Schalters auseinandergeschwenkt werden. Dadurch werden sie aber mit ihrer Spitze, an welcher sich der abzureißende Lichtbogen zuerst bildet, aus dem wirksamsten Teil des Blasfeldes in radialer Richtung herausgedreht.According to the drawing of that patent specification, the tear-off electrodes also have both or only one pivot point at its foot end, around which it is pivoted apart when the switch is actuated will. As a result, however, they are formed with their tip, at which the arc to be torn off first forms unscrewed the most effective part of the blown field in the radial direction.
Nach der vorliegenden Erfindung bleibt der Abstand zwischen Spule und Abreißelektroden bei Betätigung des Schalters unveränderlich. Danach erfolgt das Auseinanderrücken der Elektroden konzentrisch mit der Blasspule.According to the present invention, the distance between the coil and the tear-off electrodes remains unchangeable when the switch is operated. Then the moving apart takes place Electrodes concentric with the blowing coil.
In der Zeichnung bedeutet α den Hauptschalter, b und c die Elektroden, deren Abreißstelle bei d liegt. Die Elektroden b, c werden in entgegengesetzter Richtung vom Strom durchflossen wie die Blasspule e, welche auf den im Querschnitt U-förmigen Eisenrahmen I gewickelt ist. Der Schalter α ist wieder beispielsweise im inneren Hohlraum ο der Blasspule β untergebracht und wird mittels der konzentrisch liegenden Schalterwelle h betätigt. Bei der Öffnung des Schalters α nimmt der Anschlag q den radialen Arm k, welcher lose auf der Welle h sitzt, und dessen äußeres Ende mit der Elektrode b verbunden ist, mit und bewegt auf diese Weise die bewegliche Abreißelektrode b konzentrisch bis zum Anschlag an die Isolierplatte fi. In the drawing, α means the main switch, b and c the electrodes, the tear-off point of which is at d. The electrodes b, c are traversed by the current in the opposite direction to the blowing coil e, which is wound on the iron frame I, which is U-shaped in cross-section. The switch α is again accommodated, for example, in the inner cavity ο of the blowing coil β and is actuated by means of the concentric switch shaft h. When the switch α is opened, the stop q takes the radial arm k, which sits loosely on the shaft h , and whose outer end is connected to the electrode b , and in this way moves the movable tear-off electrode b concentrically up to the stop on the Isolation plate fi.
Bei kleineren Schaltertypen können Schalter- und Abreißkontakte vereinigt werden, d. h. die Blasspule dient zum Löschen des Ausschaltlichtbogens, der sich zwischen den Schalterelektroden (Bürsten, Messern o. dgl.) selbst bildet.In the case of smaller switch types, switch and tear-off contacts can be combined, i. H. The blower coil is used to extinguish the switch-off arc between the switch electrodes (Brushes, knives or the like.) Forms itself.
