Description

Zum Umschalten von Apparaten, die an ein Wechselstromverteilungsnetz angeschlossen sind, beispielsweise zum Fernsteuern von Tarifapparaten, ist es bekannt, Relais zu verwenden, die mit dem Netz gekoppelt sind und auf eine bestimmte, von der Netzfrequenz abweichende Frequenz, zweckmäßig eine Tonfrequenz, ansprechen. Bei den bekannten Frequenzrelais wird eine auf eine bestimmte Frequenz abgestimmte Zunge durch einen mit einem Strom dieser Frequenz gespeisten Elektromagneten in Schwingung versetzt. Beispielsweise betätigt diese Zunge unmittelbar oder mittels eines besonderen Getriebes einen Schalter, der beispielsweise das Doppelzählwerk eines Tarifapparates steuert. Bildet die Zunge selbst einen Teil des Schalters, so wird dieser fortgesetzt geöffnet und geschlossen, mit der Folge, daß die Kontakte rasch verschleißen. Ist andererseits aber zwischen der Zunge und dem Schalter noch ein besonderes Getriebe angebracht, so verschwinden bei jedem Angriff auf das Getriebe rasch die Ausschläge der Zunge, und es dauert eine gewisse Zeit, bis sich in der Zunge wieder so viel Energie aufgespeichert hat, daß sie von neuem Arbeit leisten kann. Das Umschalten erfordert deshalb viel Zeit.For switching devices that are connected to an AC distribution network are connected, for example for remote control of tariff devices, it is known To use relays that are coupled to the network and on a specific, from the frequency deviating from the mains frequency, expediently a tone frequency. With the known frequency relays, one is tuned to a specific frequency Tongue by an electromagnet fed with a current of this frequency in Vibration displaced. For example, this tongue is operated directly or by means of a special gear a switch, for example the double counter a tariff apparatus controls. If the tongue itself forms part of the switch, so this is continuously opened and closed, with the result that the contacts wear out quickly. On the other hand, it is still between the tongue and the switch A special gear is attached, so disappear with every attack on the gear the tongue rashes quickly and it takes time to settle in The tongue has accumulated so much energy again that it can do work again can. Switching therefore takes a lot of time.

Ferner ist es bekannt, einen dauernd unter Strom stehenden und damit dauernd Strom verbrauchenden Hilfsmotor durch ein Gesperre normalerweise an der Drehung zu hindern und durch die Zunge dieses Gesperre freizugeben.It is also known to have a permanently energized and thus continuously power consuming auxiliary motor by a locking mechanism normally on the To prevent rotation and to release this locking mechanism through the tongue.

In allen Fällen besteht, außer den bereits erwähnten Nachteilen, auch der Übelstand, daß die Zunge in irgendeiner Weise zur mechanischen Arbeitsleistung herangezogen wird. Dadurch wird aber die Resonanz der Zunge gestört, und es besteht die Gefahr, daß sie außer Tritt fällt, bevor sie ihre Arbeit zu Ende geführt hat.In all cases, apart from the disadvantages already mentioned, there is also the disadvantage that the tongue in any way contributes to mechanical work is used. This disrupts the tongue's resonance, and it persists the danger of falling out of step before she has finished her job.

Die Erfindung bezweckt, ein Frequenzrelais mit einer auf eine bestimmte Frequenz abgestimmten Zunge zu schaffen, das die Nachteile der bekannten Frequenzrelais dieser Art vermeidet. Dies wird erfindungsgemäß dadurch erreicht, daß in den beiden Luftspalten zwischen den Polen eines permanenten .Magneten und einem auf dem freien Ende der Zunge angebrachten Plättchen aus hochkoerzitiv em magnetischem Stoff je eine Wismutspirale angeordnet ist, die in einer Brückenschaltung liegen, in deren Nullzweig ein Relais geschaltet ist. Im Ruhezustand der Zunge ist die Brücke im Gleichgewicht, und das Relais im Nullzweig ist unerregt. Beim Schwingen der Zunge ändert sich der die Wismutspiralen durchsetzende Magnetfluß und bewirkt dadurch eine Widerstandsänderung der Wismutspiralen und eine Verstimmung der Brücke, wodurch das Relais im Nullzweig Spannung erhält und anspricht. Die Zunge wird hierbei also nicht zur mechanischen Arbeitsleistung herangezogen, sondern kann frei schwingen und äußerst selektiv auf die Steuerfrequenz abgestimmt werden.The invention aims to provide a frequency relay with a on a certain Frequency-tuned reed to create the disadvantages of the known frequency relays this type avoids. This is achieved according to the invention in that in the two Air gaps between the poles of a permanent magnet and one on the open At the end of the tongue attached plates made of highly coercive magnetic material each a bismuth spiral is arranged, which lie in a bridge circuit in which A relay is switched. When the tongue is at rest, the bridge is in Equilibrium, and the relay in the zero branch is de-energized. When swinging the tongue the magnetic flux penetrating the bismuth spirals changes and causes it a change in resistance of the bismuth spirals and a detuning of the bridge, whereby the relay in the neutral branch receives voltage and responds. So the tongue becomes here not used for mechanical work performance, but can swing freely and can be tuned extremely selectively to the control frequency.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Mit r ist der von der Steuerfrequenz erregte Elektromagnet bezeichnet, der zur Erregung der Resonanzzunge 2 dient, die an ihrem freien Ende ein kleines Plättchen 3 aus hochkoerzitivem Magnetstahl trägt. Die Zunge 2 schwingt in Richtung des einen gezeichneten Doppelpfeiles. Das Plättchen 3 ist zwischen den Polen eines permanenten Magneten q angeordnet, und in den beiden Luftspalten zwischen diesen Polen und den Enden des Plättchens 3 befindet sich je eine «'ismutspirale 5. Die beiden Wismutspiralen sind zu einer nicht dargestellten Brücke zusammengeschaltet, in deren Nullzweig ein empfindliches Relais geschaltet ist, das unerregt ist, solange die Zunge 2 in Ruhe und die Brücke im Gleichgewicht ist. Wenn durch Erregung des Elektromagneten r durch die Steuerfrequenz die Zunge 2 zum Schwingen gebracht wird, ändert sich der die Wismutspiralen durchsetzende Magnetfluß und infolgedessen der Widerstand der Wismutspiralen. Dadurch wird das Gleichgewicht der Brücke gestört und das im Nullzweig liegende Relais erregt.The electromagnet excited by the control frequency is denoted by r, which is used to excite the resonance tongue 2, which has a small at its free end Carries plate 3 made of high-coercive magnetic steel. The tongue 2 swings towards of the drawn double arrow. The plate 3 is one between the poles permanent magnets q arranged, and in the two air gaps between them Poles and the ends of the plate 3 are each a "'ismutspirale 5. Die both bismuth spirals are interconnected to form a bridge, not shown, A sensitive relay is switched in the zero branch, which is de-energized as long as it is tongue 2 is at rest and the bridge is in equilibrium. If by excitement of the Electromagnet r, tongue 2 is made to vibrate by the control frequency, the magnetic flux penetrating the bismuth spirals changes, and consequently the Resistance of the bismuth spirals. This disturbs the balance of the bridge and the relay in the zero branch is energized.
