Description

Bei den. bisher bekannten Einrichtungen zur Steuerung· von gas- oder dampfgefüllten Entladungsgef äßen, bei. denen durch Steuerung der Zündeinsatzpunkte mit Hilfe einer Phasenverschiebung zwischen der Anoden- und !einer Gitterwechselspann'ung die Entladung in dem 'elektrischen Entladungsgefäß geregelt wird, ergeben sich in der Hinsicht Schwierigkeiten, daß die Größe der Spannung des Steuergitters, durch, die das Einsetzen einer Entladung zwischen Kathode und Anode ermöglicht wird, von dem jeweiligen Betriebszustand des Entladungsgefäßes abhängig ist. Infolgedessen verliert jedoch.Both. previously known devices for the control of gas or steam-filled Discharge vessels, at. those through control the ignition start points with the help of a phase shift between the anode and! an alternating grid voltage, the discharge is regulated in the 'electrical discharge vessel, arise in the respect Difficulties that the size of the tension of the control grid, due to which the insertion a discharge between cathode and anode is made possible, depending on the respective operating state of the discharge vessel is. As a result, however, loses.

die Steuerung von Entladungsgiefäßen mit Hilfe einer Phasenverschiebung zwischen der Anodenspannung und der Gitterwechselspannung ihre für die meisten Anwendungen notwendige Genauigkeit, was namentlich fürthe control of discharge vessels with the help of a phase shift between the Anode voltage and the alternating grid voltage are necessary for most applications Accuracy, what specifically for

ao Schaltröhre sehr beachtlich, ist.ao interrupter is very considerable.

Bei der vorliegenden Steuereinrichtung werden diese Nachteile in vorteilhafter Weise dadurch vermieden, daß bei leinem Schaltrohr, das zum Steuern des Stromes einer zwischen der Hauptanode und der Kathode gielegten Wechselspannung beliebiger Frequenz dient und außer der Hauptentladung eine in der Phase gegenüber der Hauptentladung regelbare Hilfsentladung aufweist, erfindungsgemaß die Wirkung einer zwischen Hauptanode und Kathode vorgesehenen Sperrzone, "beispielsweise eines dauernd negativ geladenen Gitters, durch eine Neutralisation zwischen Sperrzone und Kathode vermittels einer Hilfsentladung aufgehoben wird, der zur Bestimmung des Einsetzens der Hauptentladung eine einstellbare Phasenverschiebung gegeben wird. Hierbei kann die Vorrichtung zur Veränderung· der Phasenlage zwischen Kathode und Hauptanode und zwischen Kathode und Hilfsr anode geschaltet werden.In the present control device, these disadvantages are advantageously eliminated avoided that with leinem switching tube, which is used to control the current between the main anode and the cathode AC voltage of any frequency is used and, in addition to the main discharge, one in the Phase compared to the main discharge has controllable auxiliary discharge, according to the invention the effect of a blocking zone provided between the main anode and cathode, "for example of a permanently negatively charged grid, through a neutralization between Exclusion zone and cathode is canceled by means of an auxiliary discharge, which is used to determine the onset of the main discharge is given an adjustable phase shift. The device for changing the phase position between the cathode and Main anode and between the cathode and auxiliary anode are connected.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung wiedergegeben. In der Figur bedeuten: 1 eine beliebige Elektronenquelle (Kathode), 2 die Hauptanode, 3 eine *5 Sperrzone, z. B. ein mit konstantem negativem Potential beaufschlagtes Sperrgitter, 4 und 5 zwei Hilfsanoden. Mit T ist ein Hilfstransformator, mit V lein Verbraucher und mit P eine beliebige Vorrichtung zur Veränderung der Phasenlage zwischen den Wechselspannungen bezeichnet, die an der Anode 2 und an den Hilfsanoden 4 bzw. 5 liegen. Die Wirkungsweise der Einrichtung ist folgende:An exemplary embodiment of the invention is shown in the drawing. In the figure: 1 any electron source (cathode), 2 the main anode, 3 a * 5 blocking zone, e.g. B. an applied with a constant negative potential barrier grid, 4 and 5 two auxiliary anodes. T is an auxiliary transformer, V is a consumer and P is any device for changing the phase position between the alternating voltages that are applied to the anode 2 and the auxiliary anodes 4 and 5, respectively. The device works as follows:

Durch die Sperrzone 3 wird eine Entladung zwischen der Kathode r und der Anode 2 verhindert, auch, wenn an der Anode 2 eine positive Halbwelle anliegt, da die von der Kathode 1 austretenden Elektronen durch, die negative Ladung des Gitters zur Kathode zurückgestoßen werden und deshalb eine Ionisation des Entladungsweges nicht 'einsetzen kann. Wird jedoch, die Hilfsentladung zwischen der Kathode 1 und beispielsweise der Hilfsanode 4 eingeleitet, so tritt eine Ionisation in diesem Entladungsweg ein, und dieThe blocking zone 3 prevents a discharge between the cathode r and the anode 2, even if there is a positive at the anode 2 Half-wave is applied because the electrons emerging from the cathode 1 through the negative charge of the grid are repelled back to the cathode and therefore an ionization of the discharge path cannot 'begin. However, the auxiliary discharge between of the cathode 1 and, for example, the auxiliary anode 4, an ionization occurs in this discharge path, and the

negative Ladung des Gitters 3 wird durch, die in ihre Nähe gebrachten Ionen neutralisiert, so daß nun die Sperrzone "ihre Sperrwirkung· verliert und die Hauptentladung zwischen der Kathode 1 und der Hauptanode 2 einsetzt, da die Hauptanode vermöge ihrer höheren, Spannung die Stromfuhrung übernimmt. Ist der StromduT'chgang in dem Häuptentla,-dungsweg zwischen der Kathode 1 und der Hauptanode 2 beendet und erlischt gleichzeitig die zugehörige Hälfsientladung, so erhält die Sperrzone ihre Sperrwirkung wieder zurück, und das Gefäß ist für einen neuen steuerbaren Arbeitsvorgang bereit. DurehEinstellen der Phasenverschiebung zwischen der der Hauptanode und den Hilfsanoden aufgedrückten Wechselspannung· ist also der Zeitpunkt der Zündung der Hauptentladung innerhalb 'einer Wechselstromperiode beliebig einstellbar und damit der Mittelwert des dem Gefäß entnommenen Stromes nach der bekannten Charakteristik gesteuerter Röhren beliebig regelbar.negative charge of the grid 3 is neutralized by the ions brought near it, so that now the exclusion zone "its blocking effect loses and the main discharge begins between cathode 1 and main anode 2, because the main anode takes over the current supply because of its higher voltage. is the StromduT'chgang in the main discharge, -dungsweg between the cathode 1 and the Main anode 2 terminates and at the same time goes out the associated half-discharge, so receives the blocking zone returns its blocking effect and the vessel is ready for a new one controllable work process ready. Adjust the phase shift between that of the main anode and the auxiliary anodes AC voltage · is therefore the time of ignition of the main discharge within 'of an alternating current period can be set as required and thus the mean value of the dem Any current drawn from the vessel according to the well-known characteristics of controlled tubes adjustable.
