Einrichtung zur selbsttätigen Regelung oder Unterbrechung eines WechselstromesDevice for automatic regulation or interruption of an alternating current

mittels in den Stromkreis eingeschalteter, zur Regelung von Wechselstromby means of switched on in the circuit, for the regulation of alternating current

bekannter Elektronenröhren mit zwei Glühkathoden.known electron tubes with two hot cathodes.

Patentiert im Deutschen Reiche vom 31. März 1922 ab.Patented in the German Empire on March 31, 1922.

Es sind Einrichtungen bekannt geworden, bei denen Elektronenröhren nach Art eines regelbaren Widerstandes verwendet werden, um durch von Hand bewirkte Einstellung die Stromstärke in einem Verbraucherkreis zu regeln. Um beide Halbwellen des Wechselstromes durchzulassen, hat man hierbei zwei glühende, Elektronen aussendende Elektroden verwendet, die zeitlieh abwechselnd als Anode und Kathode dienen und sich gegenseitig durch Elektronenstoß heizen.There are devices are known in which electron tubes in the manner of a adjustable resistance can be used by manual adjustment to regulate the amperage in a consumer circuit. Around both half-waves of the alternating current to let through, you have two glowing electrodes that emit electrons used, which serve alternately as anode and cathode and each other heat by electron impact.

Die Erfindung betrifft eine Einrichtung mitThe invention relates to a device with

derartigen Elektronenröhren, bei welcher die Regelung öder Unterbrechung eines Wechselstromes selbsttätig erfolgt. Dies wird dadurch erreicht, daß von dem zu überwachenden Stromkreis ein zusätzliches magnetisches Feld erzeugt wird, das die Elektronen aus ,der Bahn zwischen den Elektroden mehr oder weniger ablenkt und dadurch schließlich den Stromkreis, in dem die Röhre eingeschaltet ίο ist, gänzlich unterbricht.such electron tubes in which the regulation or interruption of an alternating current takes place automatically. This is achieved by having to be monitored An additional magnetic field is generated, which the electrons from the Path between the electrodes more or less deflects and thereby ultimately the Circuit in which the tube is switched on ίο is completely interrupted.

'Die zu überwachende Spannung kann z. B. die Spannung des Verbrauchers selbst sein. Die Abbildungen veranschaulichen zwei Ausführungsbeispiele. Abb. ι zeigt die Verwendung einer derartigen Elektronenröhre, welche den Strom in beiden Richtungen durchläßt. q ist ein Wechselstromgenerator, t ein Transformator, e das Elektronenrohr, dessen beide als Spiraldrähte ausgeführten Elektroden ev e% mittels der Heiztransformatoren A1, A2 geheizt werden, so daß bei jeder Stromrichtung eine von ihnen als Glühkathode dient. Die Elektronenröhre ist in Reihe mit dem Verbraucher ν in den Sekundärkreis des Transformators t geschaltet. Es ist der Raum zwischen den Elektroden^, e2 des Elektronenrohres einem beispielsweise durch zwei Spulen S1, S2 erzeugten magnetischen Feld ausgesetzt, dessen Stärke z. B. von einer konstant zu haltenden Span- mingsp am Verbraucher ν abhängt. Es wird dadurch der Elektronenstrom abgelenkt, und zwar werden bei einer bestimmten Stärke des Magnetfeldes die Elektronenbahnen, wie in Abb. ι punktiert angedeutet, so stark gekrümmt, daß die Elektronen zur Ausgangsplatte zurückkehren, daß also der Röhrenstrom unterbrochen wird. Diese Erscheinung kann zur Regelung im Verbraucherkreis benutzt werden, indem bei Überschreitung einer gewissen Spannung der Stromkreis des Verbrauchers im Elektronenrelais unterbrochen wird.'The voltage to be monitored can e.g. B. be the voltage of the consumer itself. The figures illustrate two exemplary embodiments. Fig. Ι shows the use of such an electron tube, which lets the current through in both directions. q is an alternating current generator, t a transformer, e the electron tube, the two electrodes of which are designed as spiral wires e v e% are heated by means of heating transformers A 1 , A 2 , so that one of them serves as a hot cathode for each current direction. The electron tube is connected in series with the consumer ν in the secondary circuit of the transformer t. It is the space between the electrodes ^, e 2 of the electron tube exposed to a magnetic field generated for example by two coils S 1 , S 2, the strength of which z. B. on a constant voltage to be kept mingsp at the consumer ν depends. The electron flow is thereby deflected, and at a certain strength of the magnetic field the electron trajectories, as indicated by dotted lines in Fig. This phenomenon can be used to regulate the consumer circuit by interrupting the circuit of the consumer in the electronic relay when a certain voltage is exceeded.

Bei Anordnung einer einzigen Kathode würde in diesem Falle von dem Wechselstrom des Transformators t nur die eine Halbwelle durchgelassen werden, was für die meisten Verwendungszwecke unzulässig ist,With the arrangement of a single cathode, only one half-wave would be allowed to pass through the alternating current of the transformer t in this case, which is inadmissible for most purposes,

Abb. 2 zeigt an einem Ausführungsbeispiel, in welcher Weise auch eine thermische Beheizung einer der Elektroden durch die andere bei derartigen Einrichtungen herbeigeführt werden kann. Es sind dabei die Elektroden als koachsiale Zylinder Z1, Z2 ausgeführt. Der innere Zylinder Z1 kann aus Blech gebogen sein; der äußere, Z2, besteht aus einem schraubenförmig gewundenen Draht, der an den Heiztransformator angeschlossen wird. Dieser Drahtzylinder strahlt so viel Wärme aus, daß der Innenzylinder Z1 bis zur Elektronenemission erhitzt wird. Dieser braucht also an keine Stromquelle angeschlossen zu werden.Fig. 2 shows an exemplary embodiment in which way thermal heating of one of the electrodes can also be brought about by the other in such devices. The electrodes are designed as coaxial cylinders Z 1 , Z 2 . The inner cylinder Z 1 can be bent from sheet metal; the outer one, Z 2 , consists of a helically wound wire which is connected to the heating transformer h « . This wire cylinder radiates so much heat that the inner cylinder Z 1 is heated until it emits electrons. This does not need to be connected to a power source.
