Description
Spannungsregler mit Zweielektrodenröhren Die Drfindung bezieht sich auf die Regelung der Spannung bei Wechselstrommaschinen mittels Zweielektrodenröhren.Voltage regulator with two-electrode tubes The finding relates to on the regulation of the voltage in AC machines by means of two-electrode tubes.
Bei Reglern dieser Art wird die Kathodentemperatur von der zu regelnden Größe beeinflußt..und der Anodenstrom wirkt auf die Erregerwicklung der zu regelnden Maschine. Der Glühdraht kann z. B. aus der Sekundärwicklung eines Transformators gepeist werden, dessen Primärwicklung an die Generatorklemmen angeschlossen ist. Die Röhre wird nun gewöhnlich parallel zu der Erregerwicklung des Generators geschaltet, während in Reihe mit dieser Parallelschaltung ein Widerstand gelegt ist. Nimmt nun die Generatorspannung zu, -so nimmt auch der Heizstrom zu. Der innere Widerstand der Röhre sinkt, der Anodenstrom nimmt zu, so daß der Feldstrom des Generators abnimmt und die Spannungsänderung vermindert wird. Ist eine große Regelempfindlichkeit erforderlich; so- ist es wünschenswert, die an den Enden des Glühdrahts wirksamen Spannungsschwankungen prozentual zu verstärken.In regulators of this type, the cathode temperature depends on the one to be regulated Size influences .. and the anode current acts on the excitation winding of the to be regulated Machine. The filament can, for. B. from the secondary winding of a transformer whose primary winding is connected to the generator terminals. The tube is now usually connected in parallel to the excitation winding of the generator, while a resistor is placed in series with this parallel connection. Take now the generator voltage increases, so the heating current also increases. The inner resistance of the tube decreases, the anode current increases, so that the field current of the generator decreases and the voltage change is reduced. A high level of control sensitivity is required; so it is desirable to control the voltage fluctuations effective at the ends of the filament to be increased as a percentage.
Nach der Erfindung wird dies dadurch erzielt, daß in Reihe mit dem Glühdraht eine Drosselspule mit gesättigtem Kern. gelegt wird.According to the invention this is achieved in that in series with the Glow wire a choke coil with a saturated core. is placed.
Die Erfindung ist in der Zeichnung beispielsweise erläutert. Die Figur ist eine schematische Darstellung der Einrichtung gemäß der Erfindung.The invention is illustrated in the drawing, for example. The figure Figure 3 is a schematic representation of the device according to the invention.
Mit i ist ein Wechselstromgenerator bezeichnet, dessen Spannung geregelt werden soll. An die Klemmen des Generators ist die Primärwicklung q. eines Transformators angeschlossen. Die Sekundärwicklung versorgt über eine mit einem Eisenkern versehene Drosselspule 6 die Kathode einer Zweielektrodenröhre 2 . mit Strom. Die Röhre 2 ist parallel zu der Feldwicklung 3 des Generators i geschaltet.With i an alternating current generator is referred to, the voltage of which is regulated shall be. The primary winding q is connected to the terminals of the generator. of a transformer connected. The secondary winding is supplied via an iron core Choke coil 6 the cathode of a two-electrode tube 2. with electricity. The tube 2 is connected in parallel to the field winding 3 of the generator i.
Der Feldstrom und der Anodenstrom für die Röhre 2 werden über einen Widerstand 7 von einer Gleichstromquelle 8 geliefert. Ist der Kern der Drosselspule 6 gesättigt, so treten die relativen Spannungsschwankungen an der Kathode in verstärktem Maße auf. Der in dieser Weise erzielte Verstärkungsgrad hängt von der Sättigung und von dem von der Drosselspule aufgenommenen Teil der in der Sekundärwicklung des Transformators hervorgerufenen Spannung. ab.The field current and the anode current for the tube 2 are via a Resistor 7 supplied from a direct current source 8. Is the core of the reactor 6 saturated, the relative voltage fluctuations at the cathode occur more intensely Dimensions on. The gain achieved in this way depends on the saturation and of the part taken up by the choke coil in the secondary winding voltage caused by the transformer. away.
