Description

Anordnung zur Erzielung-*könstänter Gittervorspannungen Im Hauptpatent ist eine Anordnung zur Erzielung konstanter Gittervorspannungen unter Schutz gestellt, die hauptsächlich bei Röhrensenderanordnungen, die bekanntlich mit großen Gitterströmen arbeiten, Verwendung finden soll. Als besonderes spannungskonstanthaltendes Mittel ist in den Gitterkreis eine Entladungsstrecke eingeschaltet, die vom Gitterstrom durchflossen wird. Diese Entladungsstrecke wird durch eine besondere Hilfsspannung in Betrieb gehalten.Arrangement for the achievement of - * Könstänter lattice prestressing in the main patent an arrangement for achieving constant grid pre-tension is placed under protection, mainly in tube transmitter arrangements, which are known to have large grid currents work, should be used. As a special means of maintaining tension a discharge path is switched into the grid circle, that of the grid current is traversed. This discharge path is created by a special auxiliary voltage kept in operation.

Gemäß der vorliegenden Erfindung werden an Stelle der Entladungsstrecke Kontaktwiderstände verwendet, die durch eine Hilfsstromquelle aktiviert sind. Derartige Widerstände sind an und für sich in der Technik z. B. für die Wechselstromgleichrichtung in Anwendung und bestehen vorzugsweise aus Kupferoxyd-, Selengleichrichterzellen u. dgl. Es eignet sich grundsätzlich jeder Widerstand, der dem Ohmschen Gesetz nicht folgt, sondern bei dem zwischen bestimmten Grenzen auch bei wechselndem Stromdurchgang der Spannungsabfall in ihm konstant bleibt. Es können also alle Leiter e-erwendung finden, bei denen der Widerstand dadurch definiert ist, daß Strom X Widerstand - konstant ist.According to the present invention, instead of the discharge path Contact resistors are used that are activated by an auxiliary power source. Such Resistances are in and of themselves in technology z. B. for AC rectification in use and preferably consist of copper oxide, selenium rectifier cells and the like. In principle, any resistance that does not comply with Ohm's law is suitable follows, but with the between certain limits also with alternating current passage the voltage drop in it remains constant. So all leaders can use it where the resistance is defined by the fact that current X resistance - is constant.

In der beiliegenden Abbildung ist .eine beispielsweise Schaltungsanordnung dargestellt, wobei zum leichteren Verständnis die gleichen Bezugszeichen gewählt sind wie im Hauptpatent. Im Gitterkreis der Röhre R liegt ein Spannungsteiler E, der aus Kontaktwiderständen besteht und der im rechten Teil von dem Gitterstr om JG durchflossen wird. Die Wirkung der Anordnung ist dieselbe wie bei der im Hauptpatent beschriebenen.The accompanying illustration shows an example of a circuit arrangement shown, where the same reference numerals have been chosen for easier understanding are as in the main patent. In the grid circle of the tube R there is a voltage divider E, which consists of contact resistors and the one in the right part of the grid stream JG is traversed. The effect of the arrangement is the same as that in the main patent described.

Wie in der Abbildung auch dargestellt, ist auch - hier die Verwendung des Spannungsteilers E zur Entnahme verschiedener Spannimgen möglich. Es ist weiterhin besonders zweckmäßig, den Stromkreis hochohmig auszubilden, damit sich der Gitterstrom am Punkt i nur in geringem Maße abzweigt und über die Stromquelle S fließt.As shown in the figure, it is also possible to use the voltage divider E here to take various voltages. It is also particularly expedient to design the circuit with high resistance so that the grid current branches off only to a small extent at point i and flows via the current source S.
