Description

Anordnung zur Steuerung von Wechselstromverbrauchern, _ die mit ein- oder mehrphasigem Wechselstrom gespeist werden" EI ist bekannt, Wechselstromverbraucher, die mit ein- oder mehrphasigem Wechselstrom gespeist werden, durch .gittergesteuerte Entladungsröhren (Hochvakuum-, Gas- oder Dampfentladungsröhren) zu steuern. Hierzu werden in den Wechselstromkreis des Ver-. brauchers zwei gesteuerte Entladungsröhren gegensinnig parallel eingeschaltet. Die Steuerung einer solchen Anordnung macht jedoch Schwierigkeiten, weil sich die Gitter der beiden. Entladungsröhren bei der Steuerung nicht auf gleichem Potential befinden.Arrangement for controlling alternating current consumers which are fed with single or multiphase alternating current " EI is known to control alternating current consumers which are fed with single or multiphase alternating current by means of grid-controlled discharge tubes (high vacuum, gas or vapor discharge tubes) If two controlled discharge tubes are switched on in opposite directions in parallel in the alternating current circuit of the consumer, however, the control of such an arrangement makes difficulties because the grids of the two discharge tubes are not at the same potential during the control.

Die Er&ndung hat sich zum Ziel gesetzt; die Steuerung eines Wechselstromkreises durch eine einzige gittergesteuerte Entladungsröhre zu bewirken und dadurch die obenerwähnten Schwierigkeiten.zu vermeiden. Gemäß der Erfindung wird deshalb der ein-oder mehrphasige Wechselstrom an einer geeigneten Stelle des Stromkreises mit Hilfe an sich bekannter Gleichrichterschaltungen (beispielsweise Graetz- und Wehnelt-Schaltung) gleichgerichtet und über eine zur Steuerung dienende gittergesteuerte Entladungsröhre geführt.The invention has set itself the goal; the control of an AC circuit by a single grid-controlled discharge tube and thereby the to avoid the difficulties mentioned above. According to the invention is therefore the single or multi-phase alternating current at a suitable point in the circuit with Help with known rectifier circuits (e.g. Graetz and Wehnelt circuits) rectified and via a grid-controlled discharge tube used for control guided.

In den Ab b. r, z und 3 der Zeichnung sind Ausführungsbeispiele der Erfindung in Schaltbildern wiedergegeben.In the ab b. r, z and 3 of the drawing, exemplary embodiments of the invention are shown in circuit diagrams.

Bei dem Ausführungsbeispiel gemäß Ab:b. i wird ein Wechselstromverbraucher i, beispielsweise der Heiztransformator einer Röntgenröhre, von dem Netz a gespeist. In der einen Zuleitung 3 zum Verbraucher i ist eine aus vier Ventilen bestehende Gleichrichteranordnung 4. in Graetzscher Schaltung eingebaut. Der gleicbgerichtete Wechselstrom wird über eine gittergesteuerte Entladungsröhre 5 geleitet. Man kann somit den Wechselstromkreis mit einer einzigen gittergesteuerten Entladungsröhre 5 beliebig steuern, beispielsweise ein-und ausschalten.In the embodiment according to Ab: b. i becomes an alternating current consumer i, for example the heating transformer of an X-ray tube, fed from the network a. In one supply line 3 to consumer i there is one consisting of four valves Rectifier arrangement 4. built in Graetzsch circuit. The same-directed Alternating current is conducted through a grid-controlled discharge tube 5. One can thus the alternating current circuit with a single grid controlled Control discharge tube 5 as desired, for example switching it on and off.

Bei dem Ausführungsbeispiel gemäß Abh. 2 wird der Wechselstromverbraucher i vom Netz z über den Transformator 6 gespeist. .Zur Gleichrichtung des Wechselstromes für die gittergesteuerte Entladungsröhre 5 im mittleren Zweig 9 ist hierbei die sog. Wehneltsche Schaltung mit zwei Ventilen 7 und 8 angewendet..In the embodiment according to Dep. 2, the alternating current consumer is i fed from the network z via the transformer 6. For rectifying the alternating current for the grid-controlled discharge tube 5 in the middle branch 9 is here the so-called Wehnelt circuit with two valves 7 and 8 applied.

Bei dem Ausführungsbeispiel gemäß Abh. 3 wird ein Drehstromverbraucher io, beispielsweise ein Elektromotor, mit Drehstrom gespeist. Die Gleichrichtung des Drehstromes für die gittergesteuerte Entladungsröhre erfolgt dabei im Sternpunkt der Speisestromquelle i i. Falls die Spe'isestromquelle keinen Nullpunkt aufweist, muB ein solcher künstlich geschaffen werden. Die Gleichrichtung erfolgt ähnlich wie bei dem Ausführungsbeispiel gemäß Abb, i über eine Anordnung 12 in Graetzsclitr Schaltung für Drehstrom mit sechs Ventilen. Zur Steuerung dient wiederum die gittergesteuerte Entladungsröhre 5. Verwendet man zur Steuerung gas- oder dampfgefüllte Entladungsröhren, so wird zweckmäßig eine Gleichrichterschältung angewendet, die pulsierende Gleichspannung liefert, da bei gas- oder dampfgefüllten Ent-Iadungsröhren die Löschung nur möglich ist, wenn die Anodenspannung zu Null wird. Bei pulsierender Gleichspannung tritt dieser Zustand. ohne weiteres ein, so daß keine besonderen Hilfsmittel zur Löschung der Entladung erforderlich sind.In the exemplary embodiment according to Dep. 3, a three-phase current consumer io, for example an electric motor, is fed with three-phase current. The rectification of the three-phase current for the grid-controlled discharge tube takes place at the star point of the supply current source i i. If the supply current source does not have a zero point, one must be created artificially. The rectification is carried out in a similar way to the exemplary embodiment according to FIG. 1 via an arrangement 12 in Graetzsclitr circuit for three-phase current with six valves. The grid-controlled discharge tube 5 is used for control Becomes zero. This condition occurs with pulsating DC voltage. without further ado, so that no special tools are required to extinguish the discharge.
