Description

Anordnung zur Verbesserung des Betriebes von Entladungsgefäßen, die nmit Dampf- oder Gasfüllung arbeiten Um eine höhere Sperrspannung den einzelnen gas- oder dampfgefüllten Entladungsgefäßen von Stromrichtern zuführen zu können, wurde bereits vorgeschlagen, in den Entladungsweg eines Entladungsgefäßes eine größere Anzahl von Zwischenelektroden einzubauen, die an einen Hochohmspannungsteiler zwischen Anode und Kathode angeschlossen sind. Auf diese Art und Weise kann es gelingen, während einer Zeit, in der keinEntionisierungsstrom (Gitterstrom) fließt, das ist im allgemeinen gegen Ende der Sperrzeit der Fall, eine gleichmäßige Aufteilung der Sperrspannung, d. h. eine gleichmäßige Feldverteilung in dem Entladungsgefäß zu erhalten, während in der Zeit, die unmittelbar an die Brennperiode des Entladungsgefäßes sich anschließt, zufolge des Entionisierungsstromes eine erheblich ungünstigere Feldverteilung auftreten kann, so daß die gleichmäßige Spannungsaufteilung vollkommen in Frage gestellt wird.Arrangement to improve the operation of discharge vessels that nWork with steam or gas filling In order to achieve a higher reverse voltage for the individual to be able to supply gas or vapor-filled discharge vessels from power converters, it has already been proposed to place a larger one in the discharge path of a discharge vessel Number of intermediate electrodes to be installed, which are connected to a high-resistance voltage divider between Anode and cathode are connected. In this way it can succeed during a time when no deionization current (grid current) flows, that is generally the case towards the end of the blocking period, an even distribution of the Reverse voltage, d. H. a uniform field distribution in the discharge vessel obtained while in the time immediately following the burning period of the discharge vessel follows, due to the deionization current a considerably less favorable one Field distribution can occur, so that the even voltage distribution is perfect is questioned.

Zur Erklärung dieser Vorgänge sei auf die Abbildungen i und 2 hingewiesen. Der Abb. i entnimmt man, daß über den Hochspannungsteiler i erstens der von der Sperrspannung durch den Spannungsteiler getriebene Ausgleichsstrom T fließt. Außerdem muß der Spannungsteiler an jeder Anschlußstelle der Zwischenelektroden 2, 3, 4,. 5 und 6 den Entionisierungsstrom i entnehmen. Der Einfachheit halber ist in der Darstellung der Abb. i, bei der im übrigen nur der Anschluß eines gas- oder dampfgefüllten Entladungsgefäßes 7 an einen mehrphasigen Transformator 8 über den Belastungswiderstand 9 dargestellt ist, angenommen, daß alle Entionisierungsströme gleich groß seien. In Wirklichkeit folgen sie dem bekannten V312-Gesetz, so daß die in Abb.2 gezeigte Spannungsverteilung noch erheblich ungünstiger wird. Der Abb.2 ist ferner noch zu entnehmen, daß die Spannungsabfälle in den Einzelgliedern des Spannungsteilers um so größer werden, je nähe? der Spannungsteilerabgriffspunkt der A;ri= schlußstelle der Anode io liegt. Unmittel'l@ anschließend an die Brennzeit treten also lii der Umgebung der Anode derartig hohe Feldstärken auf, daß die gewünschte Wirkungsweise der Anordnung in Frage gestellt ist.Please refer to Figures i and 2 for an explanation of these processes. From Fig. I one can see that the high-voltage divider i is first used by the Reverse voltage flows through the equalizing current T driven by the voltage divider. aside from that the voltage divider must be at each connection point of the intermediate electrodes 2, 3, 4,. 5 and 6 take the deionization current i. For the sake of simplicity, the Representation of Fig. I, in which only the connection of a gas or steam-filled Discharge vessel 7 to a polyphase transformer 8 via the load resistor 9, assuming that all deionization currents are equal. In reality, they follow the well-known V312 law, so the one shown in Fig Stress distribution still becomes considerably less favorable. The Fig.2 is can also be seen that the voltage drops in the individual elements of the voltage divider get the bigger, the closer? the voltage divider tap of A; ri = termination point the anode is io. Immediately after the firing time, there will be less Such high field strengths around the anode that the desired mode of action the arrangement is in question.

Erfindungsgemäß wird nun der Betrieb derartiger Entladungsgefäße dadurch verbessert, daß den einzelnen Gliedern des Hochspannungsteilers oder einer Gruppe dieser Glieder mit einem Steuergitter versehene Hilfsentladungsröhren, insbesondere Hochvakuumröhren, in der Weise unter Anschluß auch der Gitter der Hilfsentladungsröhren an den Spannungsteiler parallel geschaltet werden, daß vermöge eines entsprechenden unterschiedlichen Stromflusses in den Hilfsentladungsgefäßen Ungleichmäßigkeiten in der Spannungsverteilung, die in der Sperrzeit der Dampf- oder Gasentladungsgefäße längs des Hochohmspannungsteilers auftreten, ausgeglichen werden. In Abb. 3 ist eine derartige Anordnung dargestellt. Die Entnahme der Gitterspannung für dieHilfsentladungsgefäße vom Spannungsteiler erfolgt zweckmäßig von einem weiteren Abgriff des Spannungsteilers, wie er zwischen 11/i2 bzw. RJr dargestellt ist. Man kann es auch so einrichten, daß der Hochohmspannungsteiler Teile, z. B. 12 bzw. r, aufweist, deren Widerstand im Gegensatz zu dem der anderen Teile, i i bzw. R, mit dem Strom nicht linear ansteigt und an deren Enden die Spannungen für die Gitter der Hilfsentladungsgefäße abgenommen werden. Steigt nun der Spannungsabfall in einem Kettenglied stärker an als in einem anderen, so wird auch, wie das die Abb. q. zeigt, das Steuergitter des Hilfsentladungsgefäßes positiver und das Hilfsentladungsgefäß dadurch stromdurchlässiger. Es gelingt, die unerwünschte und gefährliche Vergrößerung der Feldstärken durch eine derartige Anordnung praktisch vollkommen zu vermeiden.The operation of such discharge vessels is now in accordance with the invention improved that the individual members of the high voltage divider or a group Auxiliary discharge tubes provided with a control grid of these members, in particular High vacuum tubes, in the same way with connection to the grids of the auxiliary discharge tubes be connected in parallel to the voltage divider that by virtue of a corresponding different current flow in the auxiliary discharge vessels in the voltage distribution that occurs in the blocking time of the vapor or gas discharge vessels occur along the high-resistance voltage divider, are compensated. In Fig. 3 is such an arrangement is shown. The removal of the grid voltage for the auxiliary discharge vessels from the voltage divider is expediently carried out by a further tap on the voltage divider, as shown between 11 / i2 or RJr. It can also be arranged that the high-resistance voltage divider parts, e.g. B. 12 or r, whose resistance in contrast to that of the other parts, i i or R, does not increase linearly with the current and at their ends the voltages for the grids of the auxiliary discharge vessels are removed will. If the voltage drop in a chain link increases more than in one others, it will also be like that in fig. q. shows the control grid of the auxiliary discharge vessel more positive and the auxiliary discharge vessel thereby more current-permeable. It succeeds undesirable and dangerous increase in the field strengths due to such an arrangement practically completely to be avoided.

*;Will man Hilfsentladungsgefäße einsparen, :@@:-braucht man nicht jedes Kettenglied mit Onem Hilfsentladungsgefäß auszurüsten, sonern kann mehrere dieser Glieder zu einer Gruppe zusammenfassen und diesen dann ein Hilfsentladungsgefäß parallel schalten. Eine derartige Anordnung zeigt die Abb. 5.*; If you want to save auxiliary discharge tubes,: @@: - you don't need it to equip each chain link with one auxiliary discharge tube, but several can combine these members into a group and then create an auxiliary discharge vessel connect in parallel. Such an arrangement is shown in Fig. 5.
