Description

Thermoschalter zum Ein- und Ausschalten von Stromkreisen Zusatz zum Patent 443 871 Die Erfindung bildet eine weitere Ausbildung des Thermoschalters zum Ein- und Ausschalten von Stromkreisen nach Patent 443871-Es hat sich bei der Ansführung dieser Schalter für verschiedene Anwendungszwecke als wünschenswert erwiesen, das Arbeiten derselben in Abhängigkeit von dem zu schaltenden Stromkreis zu bringen. Zu diesem Zweck ist gemäß der Erfindung der schwingende Stahlmagnet durch einen schwingenden Weicheisenkern ersetzt, dessen Erregung durch nicht mitschwingende Stromspulen erfolgt.Thermal switch for switching circuits on and off in addition to Patent 443,871 The invention forms a further embodiment of the thermal switch for switching circuits on and off according to patent 443871-It has been found in the These switches have been shown to be desirable for various purposes, to bring the work of the same depending on the circuit to be switched. For this purpose, according to the invention, the vibrating steel magnet is through a vibrating soft iron core replaced, its excitation by non-vibrating Power coils takes place.

Auf der Zeichnung ist die Erfindung dargestellt. Mit 3, 4, 8 ist der schwingende Wei:cheisenkern bezeichnet, von dem ein Schenkel. oder beide Schenkel 4,8 durch eine oder mehrere Magnetisierungsspulen 9, Io mit so großem Spielraum hindurchgeführt sind, daß das freie Schwingen des Kernes nicht behindert ist. Die Magnetisierungsspulen können dabei hinter- oder nebeneinandergeschaltet werden. Die Spulen können auch so angeordnet werden, daß z. B. eine Spule oder eine Gruppe von Spulen dem Strom des Verbrauchsstromkreises und eine andere Spule oder eine andere Gruppe von Spulen der Spannung des Verbrauchsstromkreises proportional erregt werden. Die Spulen können auch von einem beliebigen anderen Stromkreis ihre Erregung erhalten.The invention is shown in the drawing. With 3, 4, 8 is the swinging white: called iron core, one leg of which. or both legs 4.8 by one or more magnetizing coils 9, Io with such a large margin are passed that the free swinging of the core is not hindered. the Magnetizing coils can be connected one behind the other or next to one another. The coils can also be arranged so that, for. B. a coil or a group of coils to the current of the consumer circuit and another coil or one other group of coils energized proportionally to the voltage of the consuming circuit will. The coils can also get their excitation from any other circuit obtain.
