Description
Einrichtung zur Verstellung des Zündzeitpunktes bei gittergesteuerten Gas- oder Dampfentladungsstrecken Gegenstand des Hauptpatents 64.2 626 ist eine Einrichtung zur Verstellung des Zündzeitpunkt,es bei gittergesteuerten Gas- oder Dampfentladungsstrecken, die ihre Gitterspanntmg 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 The subject of the main patent 64.2 626 is a Device for adjusting the ignition point, it with grid-controlled gas or Vapor discharge paths that derive their grid voltage from a saturated transformer obtain. This saturated transformer has two excitation windings on the primary side equipped, which are shifted by two against each other in phase by a fixed angle Alternating currents are fed. The ignition point of the discharge paths is thereby adjusted that one of the two alternating currents or both of the amplitude is regulated will. For this purpose, according to a particular embodiment of the object of the main patent in the circuit of the relevant excitation winding a controllable Resistance can be switched.
Gegenstand der Erfindung ist eine weitere Ausgestaltung der Steuerungseinrichtung nach dem Hauptpatent, die insbesondere für selbsttätig arbeitende Regelanordnungen von Bedeutung ist. Gemäß der Erfindung ist der in den Stromkreis einer von einem veränderlichen Wechselstrom gespeisten Erregerwicklung geschaltete Widerstand seiner Größe nach vorn dem ihn durchfließenden Erregerstrom infolge seiner Beschaffenheit oder seiner Bemessung ganz oder nahezu unabhängig und auf rein elektrischem Wege, d. h. oh-ne mechanische Reglerbetätigung, z. B. durch eine Betriebsgröße der Entla.dungsstreckenanordnung steuerbar. Als rein elektrisch steuerbare und vom durchfließenden Strom uriabhjängige Widerstände können ,an sich bekannte veränderliche Widerstände, beispielsweise gittergesteuerte Elektronenrohre, strahlungsempfindliche Zellen, insbesondere Photozellen, oder auch Kohledruckregler verwendet werden. In jedem Fall ist es wichtig, daß durch veränderbare Spa:nnungs- 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 matters. According to the invention, the one in the circuit is one of one variable alternating current fed excitation winding switched resistance of its Size forward of 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 controller actuation, e.g. B. by an operating size of the Entla.dungsstreckenanordnung controllable. As purely electrically controllable and dependent on 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 else Coal pressure regulators can be used. In any case it is important that by changeable Spa: Nominal or current quantities directly a change in the resistance in the circuit the variable excitation of the grid transformer is brought about.
In der Zeichnung ist als Ausführungsbeispiel der Erfindung das Schaltungsschema eines gittergesteuerten Gleichrichters, dargestellt, dessen Gleichspannung selbsttätig erhöht werden soll, wenn die Stromstärke im Gleichstromkreis .anwächst. Den Steuergittern des Gleichrichters r sind gesättigte Gittertransformatoren 2 zugeordnet, welche je mit zwei Wechselstromerregerwicklungen 21 und 22 und mit einer Gitterspule 23 versehen sind. Der Erregerstrom der Spule 2i ist konstant, während der Strom in den Spulen 22 durch, Eisenwasserstoffwiderstände 3 geändert wird, welche mit den Erregerspulen 22 in. Reihe geschaltet sind. Die Heizwicklungen 3 i der Eisenwasserstoff-,viderstände sind an die Sekundärwicklung eines Stromwandlers 4 angeschlossen, welche im Primärkreis des Gleichrichters i liegt. An Stelle der in der Zeichnung angenommenen induktiven Heizung der Widerstände können auch direkt beheizte temperaturabhängige Widerstände verwendet werden.In the drawing is the circuit diagram as an embodiment of the invention of a grid-controlled rectifier, shown, whose DC voltage is automatic should be increased if the amperage in the direct current circuit grows. The control grids of the rectifier r 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 the current in the coils 22 through, ferrous hydrogen resistances 3 is changed, which are connected in series with the excitation coils 22. The heating coils 3 i of the ferrous hydrogen resistors are connected to the secondary winding of a current transformer 4, which is in the primary circuit of the rectifier i lies. Instead of the inductive ones assumed in the drawing Heating the resistors can also be directly heated, temperature-dependent resistors be used.
