Die Lösung der Aufgabe, die Spannung von Generatoren zum Speisen von Röhrensendern während des Betriebes konstant zu halten, bereitet bei kleinen ortsveränderlichen Generatoren, beispielsweise bei Flugzeuggeneratoren, große Schwierigkeiten, da mit Rücksicht auf Raum und Gewicht verwickelte Apparate nicht vorgesehen werden können. Man verwendet daher im allgemeinen Einrichtungen, welche eine Konstanthaltung der Drehzahl bewirken. Derartige Einrichtungen gleichen jedoch nicht die durch Temperaturschwankungen bedingten Abweichungen in den elektrischen Eigenschaften des GeneratorsThe solution to the problem, the voltage of generators for feeding tube transmitters to keep constant during operation, prepares for small portable ones Generators, for example in aircraft generators, have great difficulties because with Consideration of space and weight involved apparatus cannot be provided. Therefore, in general, devices are used which ensure that the Cause speed. However, such devices are not the same as those caused by temperature fluctuations conditional deviations in the electrical properties of the generator
tg aus und haben außerdem noch andere Nachteile, wie z. B. Ungenauigkeit und Trägheit in der Regelung.tg and also have other disadvantages, such as B. Inaccuracy and Inertia in the scheme.
Es liegt daher der Gedanke nahe, die Regelung der Spannung unmittelbar durch Beeinfiussung des Erregerstromkreises im Generator vorzunehmen, und zwar in gleicher Weise, wie das beispielsweise bei den Lichtmaschinen für Fahrzeuge durch Verwendung eines kleinen Schnellreglers (Zitterrelais)The idea is therefore to regulate the voltage directly by influencing it of the excitation circuit in the generator, in the same way as, for example, with the alternators for vehicles by using a small fast regulator (dither relay)
geschieht. Hierbei ergeben sich jedoch Störungen, welche durch die vom Regler hervorgerufenen Stromunterbrechungen bedingt sind und die besonders groß werden, wenn der vom Regler unterbrochene Stromkreis unmittelbar mit dem Nutzstromkreis des Generators, z. B. dem Heizkreise, verbunden ist.happens. However, this results in disturbances caused by the controller Power interruptions are caused and which are particularly large when the circuit is interrupted by the controller directly to the utility circuit of the generator, e.g. B. the heating circuits is connected.
Nach der Erfindung wird dieser Nachteil dadurch behoben, daß für die Entnahme des Erregerstromes eine besondere Wicklung auf dem Anker des Generators vorgesehen ist, welche mit dem Verbrauchsstromkreise metallisch nicht verbunden ist, und daß die Steuerung des in den Erregerstromkreis eingeschalteten Schnellreglers von einer Verbrauchsspannung vorgenommen wird. Hierdurch werden die durch die Stromunterbrechung des Reglers hervorgerufenen Schwingungen von den Verbrauchskreisen ferngehalten.According to the invention, this disadvantage is eliminated in that for the removal of the Excitation current a special winding is provided on the armature of the generator, which is not metallically connected to the consumer circuits, and that the control of the high-speed regulator switched into the excitation circuit from a consumption voltage is made. This removes the effects caused by the power interruption to the controller Vibrations kept away from the consumer circuits.
Es sind nun zwar an sich bereits Schaltungen bekannt, bei denen der Erregerstromkreis des Generators einer besonderen Wicklung entnommen wird. Hierbei wird aber der Zweck verfolgt, die Spannungsregelung des Generators ohne besondere äußere Hilfsmittel, d. h. also auch ohne einen Schnellregler, nach dem Prinzip des Zitterrelais zu erzielen, und nicht der Zweck, die durch einen Kontaktregler in den Nutzstromkreisen verursachten, insbesondere bei angeschlossenen Röhrensendern äußerst unangenehmen Störungen zu vermeiden.Circuits are already known per se in which the excitation circuit of the generator is taken from a special winding. But here the Purpose pursued, the voltage regulation of the generator without special external aids, d. H. So even without a fast regulator, to achieve according to the principle of the dither relay, and not the purpose caused by a contact regulator in the utility circuits, to avoid extremely unpleasant interference, especially with connected tube transmitters.
In der Zeichnung ist der Erfindungsgegenstand in zwei Ausführungsformen veranschaulicht. "In the drawing, the subject matter of the invention is illustrated in two embodiments. "
In Abb. ι trägt der Anker α drei Wicklungen, welche an die Kommutatoren b, c In Fig. Ι the armature α carries three windings which are attached to the commutators b, c

uad d geführt sind und von denen h die Anodenspanmmg, c die Heizspannung und d den Erregerstrom liefert. Der Regler e in Verbindung mit dem Widerstand / beeinflußt durch periodische Unterbrechung in bekannter Weise den Erregerstromkreis g. Der Regler wird durch den Magneten h getrennt, der an der Heiz- oder Anodenspannung liegen kann, je nachdem, welche Spannung konstant gehalten werden soll. Die Anordnung läßt sich auch sinngemäß auf einen Generator anwenden, bei welchem der Erregerstrom von einem besonderen, auf der gleichen Welle sitzenden Anker entnommen wird.uad d are performed and of which h supplies the anode voltage, c the heating voltage and d the excitation current. The controller e in conjunction with the resistor / influences the excitation circuit g by periodic interruption in a known manner. The regulator is separated by the magnet h , which can be connected to the heating or anode voltage, depending on which voltage is to be kept constant. The arrangement can also be applied analogously to a generator in which the excitation current is taken from a special armature seated on the same shaft.
Zur Verbesserung der Regelung kann der Regler mit besonderer Zusatzwicklung versehen werden, die ein gleichmäßiges Arbeiten der Kontakte bewirkt. So kann beispielsweise nach Abb. 2 eine zweite Wicklung i auf dem Kerne angeordnet werden, die vom Erregerström dttrchffossen wird. Um eine kapazitive oder induktive Beeinflussung der Spule h durch i zu vermeiden, können beide Spulen auf getrennten Kernen angeordnet werden.To improve the regulation, the controller can be provided with a special additional winding that causes the contacts to work evenly. For example, as shown in Fig. 2, a second winding i can be arranged on the core, which is dttrchffossen from the excitation current. In order to avoid a capacitive or inductive influence on the coil h by i , both coils can be arranged on separate cores.
