Description
Einrichtung zur Verstellung des Zündzeitpunktes bei gittergesteuerten Gas- oder Dampfentladungsstrecken Zusatz zum Patent 642 626 Gegenstand des Hauptpatents 642 626 ist eine Einrichtung zur Verstellung des Zündzeitpunktes bei gittergesteuerten Gas- -oder Dampfentladungsstrecken, die ihre Gitterspannung aus einem gesättigten Transformator erhalten. Dieser gesättigte Transformator ist primärseitig mit zwei Erregerwicklungen ausgerüstet, die von zwei gegeneinander in der Phase um einen festen Winkel verschobenen Wechselströmen gespeist werden. Der Zündpunkt der Entladungsstrecken wird dadurch verstellt, daß der eine der beiden Wechselströme oder beide der Amplitude nach geregelt werden. Zu diesem Zweck kann gemäß einer besonderen Ausführungsform des Gegenstandes des Hauptpatents in den Stromkreis der betreffenden Erregerwicklung ein regelbarer Widerstand geschaltet werden.Device for adjusting the ignition timing for grid-controlled Gas or vapor discharge paths Addition to patent 642 626, subject of the main patent 642 626 is a device for adjusting the ignition point in grid-controlled Gas or vapor discharge paths that derive their grid tension from a saturated Transformer received. This saturated transformer is primary with two Equipped excitation windings, which of two against each other in phase to one Fixed angle shifted alternating currents are fed. The ignition point of the discharge paths is adjusted by the fact that one of the two alternating currents or both of the amplitude to be regulated. For this purpose, according to a particular embodiment the subject of the main patent in the circuit of the relevant excitation winding an adjustable resistor can be switched.
Gegenstand der Erfindung ist eine weitere Ausgestaltung der Steuerungseinrichtung nach dem Hauptpatent, die insbesondere für selbsttätig arbeitende Regelanordnungen von Bedeutuing ist. Gemäß der Er findimg ist der in den Stromkreis einer von einem veränderlichen Wechselstrom gespeisten Erregerwicklung geschaltete Widerstand seiner Größe nach von dem ihn durchfließenden Erregerstrom infolge seiner Beschaffenheit oder seiner Bemessung ganz oder nahezu unabhängig und auf rein elektrischem Wege, d. h. ohne mechanische Reglerbetätigung, z. B. durch eine Betriebsgröße der Entladungsstreckenanordnung steuerbar. Als rein elektrisch steuerbare und vom durchfließenden Strom unabhängige Widerstände können an sich bekannte veränderliche Widerstände, beispielsweise gittergesteuerte Elektronenrohre, strahlungse mpfIndliche Zellen, insbesondere Photozellen, oder auch Kohledruckregler verwendet werden. In jedem Fall ist es wichtig, daß durch veränderbare Spannungs- oder Stromgrößen direkt eine Änderung des Widerstandes im Stromkreis der veränderlichen Erregung des Gittertransformators herbeigeführt wird.The invention relates to a further embodiment of the control device according to the main patent, in particular for automatic control arrangements is of importance. According to the He findimg, the one in the circuit is one of one variable alternating current fed excitation winding switched resistance of its Size according to the excitation current flowing through it due to its nature or its dimensioning completely or almost independently and in a purely electrical way, d. H. without mechanical control operation, e.g. B. by an operating variable of the discharge path arrangement controllable. As purely electrically controllable and independent of the current flowing through it Resistors can be variable resistances known per se, for example grid-controlled ones Electron tubes, radiation-sensitive cells, especially photocells, or coal pressure regulators can also be used. In any case, it is important that through Changeable voltage or current values directly change the resistance in the Circuit of the variable excitation of the grid transformer is brought about.

The control grids of the rectifier i are assigned saturated grid transformers 2, which ever with two AC excitation windings 21 and 22 and with one Grid coil 23 are provided: The excitation current of the coil 2i is constant while he current in the coils 22 by ferrous hydrogen resistance 3 winds which are connected in series with the excitation coils 22. The heating coils 3 i the, Hydrogen iron resistors are connected to the secondary winding of a current transformer q. connected, which is in the primary circuit of the rectifier i. Instead of the in the drawing assumed inductive heating of the resistors can also be used directly heated temperature-dependent resistors can be used.
