Description
In vielen Fällen ist bei Schaltern für kleinere Leistung in induktiven Stromkreisen 'die Anbringung- einer Blasspule aus Rücksicht auf den Preis oder wegen Platzmangels nicht mög-IiA, andernteils aber zur Vermeidung eines Stehlichtbogens die Anbringung einer einfachen und idooh sicher . wirkenden Unterbrechungsvorrichtung unerläßlich.In many cases, switches for smaller power in inductive circuits are 'the Attachment of a blowing coil out of consideration for the price or due to lack of space not possible-IiA, on the other hand, to avoid a standing arc, the attachment of a simple one and idooh sure. acting interruption device indispensable.
Man hat daher diese Anforderung durch einOne therefore has this requirement through a
ίο vom beweglichen Schaltkontakt selbst gesteuertes, feuerfestes Isolierstück erfüllt,, 'das um eine feste Achse schwenkbar ist und sich mindestens bei geschlossenem Schalter gegen den beweglichen Schaltkontakt stützt; während der Sdhaltbewiegung schiebt es sich durch Gewichts- oder Federkraft zwischen die beiden Schaltkontakte, ·. wodurch; eine vollständige Trennung der Kontakte und eine Unterbrechung des Lichtbogens erreicht wird.ίο controlled by the movable switching contact, refractory insulating piece fulfills ,, 'which is pivotable about a fixed axis and is at least when the switch is closed, supports against the moving switch contact; during the By means of weight or spring force, it pushes itself between the two by means of weight or spring force Switching contacts, ·. through which; a complete separation of contacts and an interruption of the arc is reached.
ao Um nun eine sichere Führung des Isolierstückes
zu erreichen, ist es, erfindungsgemäß plattenförmig, als sogenannter Funkenfädher,
ausgebildet, der um eine in oder parallel der Plattenebene liegende Achse schwenkbar ist,
und der bewegliche Schaltkontakt wind so geführt, daß er sich beim Ausschalten der
Schwenkachse der Isolierplatte nähert.
Zur Erläuterung der Wirkungsweise möge das in der Zeichnung dargestellte Ausführungsbeispiel dienen. Der darin veranschaulichte
Schalter wird durch Drehung der Schalterachse
α von der ausgezogenen Schließlage in die
strichpunktierte Offenlage gebracht.ao In order to achieve safe guidance of the insulating piece, it is, according to the invention, plate-shaped, designed as a so-called spark threading device, which can be pivoted about an axis lying in or parallel to the plane of the plate, and the movable switching contact is guided so that it moves when the Approaching the pivot axis of the insulating plate.
The exemplary embodiment shown in the drawing may serve to explain the mode of operation. The switch illustrated therein is brought from the extended closed position into the dash-dotted open position by rotating the switch axis α.
Der zu unterbrechende Strom verläuft vom festen Kontakt b über den um die Achse α drehbaren Kontakt c. Bei der Ausschaitbewegung schiebt sich das; um den festen Punkt d drehbare Isolierstücke durch den Druck der Feder/ zwischen die beiden sich voneinander entfernenden Kontakte 5 und c; 'dadurch, daß sich dabei der bewegliche Kontakt c der ■Schwenkachse d des Funkenfächers e nähert, legt sich dieser mit dem unteren Ende auf die Isolierbeilage g des Kontaktes c und unterbricht dadurch den zwischen den Kontakten b und' c auftretenden Lichtbogen. Beim Wiedereinschalten wird die Trennwand e durch den beweglichen Kontakt c hochgehoben.The current to be interrupted runs from the fixed contact b via the contact c, which is rotatable about the axis α. During the opening movement, this is pushed; Insulating pieces rotatable about the fixed point d by the pressure of the spring / between the two spaced apart contacts 5 and c; Because the movable contact c approaches the pivot axis d of the spark fan e , the latter rests with the lower end on the insulating shim g of the contact c and thereby interrupts the arc occurring between the contacts b and 'c. When switching on again, the partition e is lifted up by the movable contact c.
