Description

Bei elektrischen dampf- oder gasgefüllten Ent4 ladungsröhren für sehr hohe Spannungen ergeben sich für die Steuerung oftmals Schwierigkeiten. Diese sind vor allem dann gegeben, wenn; was häufig der Fall ist, die Kathode auf hoher Spannurig .ist. Man ist in diesem Fall gezwungen; sowohl für die Heizung wie auch für die Gittersteuerung hochisolierte Spannungswandler vorzusehen.For electric vapor or gas-filled discharge tubes for very high voltages often result in difficulties for the control. These are especially given when; which is often the case, the cathode on high voltage .is. In this case one is forced; both for heating and for Grid control to provide highly isolated voltage transformers.

Die Erfindung betrifft ein Steuerverfahren. für derartige Hochspannungsröhren, wobei diese Schwierigkeit vermieden ist und nur ein hochisolierter Spannungswandler vorhanden zu sein braucht. Erfindungsgemäß ist nur der Heizwandler gegen Hochspannung isoliert, und die Steuerspannung wird von der Hochspannungsseite dieses Wandlers abgenommen. Zur Regelung wird die Primärspannung in ihrer Phase, z. B. durch einen Drehregler, verschoben.The invention relates to a control method. for such high-voltage tubes, whereby this difficulty is avoided and only a highly isolated voltage converter needs to be present. According to the invention, only the heating converter is against high voltage isolated, and the control voltage comes from the high voltage side of this converter removed. For regulation, the primary voltage is used in its phase, e.g. B. by a Rotary control, moved.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung für einen 3phasigen Gleichrichter dargestellt. Hier bedeutet T einen Hochspannungstransformator, der primärseitig von. dem Drehstromnetz U, V, W gespeist wird. Der sekundäre Sternpunkt ist bei E geerdet. Die Entladungsröhre i wird von der Phase U' gespeist. Die anderen zwei Phasen sind der Übersichtlichkeit wegen nichtgezeichnet und müssen sinngemäß ergänzt werden. Die Kathode K wird von einem Transformator H geheizt, der gegen Hochspannung isoliert ist. Die Steuerung des Gitters G erfolgt von der Sekundarseite des Heiztransformators aus. In üblicher Weise werden dem Gitter vermittels des Vorspanngerätes. a eine negative Gleichspannung und mit Hilfe eines Steuertransformators St positive Spannungsimpulse zugeführt. Die Phasenverschiebung erfolgt erfindungsgemäß durch einen Phasenschieher; z. B. einen Drehregler D, -der in die Primärwicklung -des Heiztransformators H eingeschaltet ist.The drawing shows an embodiment of the invention for a 3-phase rectifier. Here T means a high voltage transformer, the primary side of. the three-phase network U, V, W is fed. The secondary star point is grounded at E. The discharge tube i is fed by the phase U '. The other two phases are not shown for the sake of clarity and must be supplemented accordingly. The cathode K is heated by a transformer H, which is insulated from high voltage. The grid G is controlled from the secondary side of the filament transformer. In the usual way, the grating by means of the prestressing device. a negative DC voltage and with the help of a control transformer St positive voltage pulses are supplied. According to the invention, the phase shift takes place by means of a phase shifter; z. B. a rotary control D, -the heating transformer H is switched on in the primary winding.
