Description
Die Erfindung betrifft eine Schaltanordnung zur Erzielung einer kurzzeitigen Spannungsspitze zur Gitterbeeinflussung von gas- oder dampfgefüllten Entladungsstrecken unter Verwendung von einer der Gitterzahl entsprechenden Anzahl von Gitterstromkreisen, die Kapazitäten und Ohmsche Widerstände !enthalten und nur die positive Halbwelle der Gitterwechselspannung hindurchlassen, die negative dagegen vom Gitter fernhalten.The invention relates to a switching arrangement for achieving a brief voltage spike for influencing the grid of gas or vapor-filled discharge paths using of a number of grid circuits corresponding to the grid number, the capacitances and ohmic resistances! and only the positive half-wave of the alternating grid voltage let through, but keep the negative ones away from the grid.
Es ist bereits vorgeschlagen worden, eine positive Zündspannung ohne Hilfsentladungsgefäße dadurch zu gewinnen, daß die positive Halbwelle allein ausgenutzt wird, wähnend die negative entfällt, und daß die negative Gittervorspannung durch geeignete Schaltelemente herbeigeführt wird, indem die Gleichstromkomponente im Gitterkreis beseitigt wird.A positive ignition voltage without auxiliary discharge vessels has already been proposed to gain by the fact that the positive half-wave is used alone, while the negative is omitted, and that the negative Grid bias is brought about by suitable switching elements by adding the direct current component is eliminated in the grid circle.
Im Gegensatz dazu besteht die Erfindung in der Verwendung einer Reihenschaltung der Gittertransformatorwicklung mit einem Gleichrichter, hinter dem die eine Belegung eines Gitterkondensators angeschlossen ist, mit einem Widerstand, einem zweiten Gleichrichter, hinter dem das Katbodenpotential liegt, sowie einem zweiten Widerstand, der bei gemeinsamer Kathode alle Gitter ströme übernimmt, und dessen Endpunkt einerseits über einen dritten Widerstand an die gitterseitige zweite Belegung des Gitterkondensators geführt ist, anderseits an einer Glättungsdrossel liegt, deren freies Ende an die Rückleitung zum Gittertransformatorsternpunkt angeschlossen ist.In contrast, the invention consists in the use of a series connection of the Grid transformer winding with a rectifier, behind which the one assignment of a Grid capacitor is connected, with a resistor, a second rectifier, behind which the Katbodenpotential lies, as well as a second resistance, which with common Cathode takes over all grid currents, and its end point on the one hand via a third resistor to the grid-side second assignment of the grid capacitor is performed, on the other hand on a smoothing choke whose free end is connected to the return line to the grid transformer star point is.
