Description
Elektrischer Kondensator in Form einer gasgefüllten Röhre Gegenstand der vorliegenden Erfindung ist ein elektrischer Kondensator in Form einer gasgefüllten Röhre.Electric capacitor in the form of a gas-filled tube object The present invention is an electrical capacitor in the form of a gas-filled Tube.
-Es sind elektrische Kondensatoren bekannt, bei denen die eine Belegung oder auch beide aus einem elektrisch leitenden Gas bestehen. Das Dielek trikum dieser Kondensatoren wird durch den die beiden Gasschichten voneinander trennenden Glaskörper gebildet. Die Kapazität dieser Kondensatoren ist mit Rücksicht auf die Stärke des Dielektrikums nur gering. Gemäß der Erfindung werden größere Kapazitätswerte dadurch erreicht, daß als die eine Belegung ein Ventilmetall verwendet ist, die in ein solches die zweite Belegung bildendes elektrisch leitendes Gas gesetzt ist, das mit dem Ventilmetall der ersten Belegung eine die Eigenschaften einer dielektrischen Sperrschicht besitzende chemische Verbindung eingeht. Es ist bekannt, zur Vermeidung von Rückkopplungsschwingungen bei gasgefüllten Audionlampen die Anode aus einem Ventilmetall zu fertigen und diese zur Erhöhung des Widerstandes zwischen Anode und Gasschicht mit einer schlecht leitenden Oxydschicht zu überziehen. Auf diese Weise ist verhindert, daß eine Entladung des aus den beiden Elektroden der Röhre gebildeten Kondensators stattfindet und unerwünschte Rückkopplungsschwingungen auftreten.-Electrical capacitors are known in which one occupancy or both consist of an electrically conductive gas. The dielectric of this Capacitors are created by the glass body separating the two gas layers from one another educated. The capacitance of these capacitors is dependent on the strength of the Dielectric only slightly. According to the invention, larger capacitance values are thereby obtained achieves that a valve metal is used as the one occupancy, which is in such a the second coating forming electrically conductive gas is set, which with the Valve metal of the first occupancy has the properties of a dielectric barrier layer owning chemical compound. It is known to avoid feedback oscillations in the case of gas-filled audio lamps, to manufacture the anode from a valve metal and this to increase the resistance between anode and gas layer with a poorly conductive one Oxide layer to be coated. This prevents the The capacitor formed by the two electrodes of the tube takes place and is undesirable Feedback oscillations occur.
Bei dem Kondensator . gemäß der Erfindung wird nun gleichfalls eine gasgefüllte Röhre verwendet, deren Anode aus einem Ventilmetall besteht, die mit einer nichtleitenden dielektrischen Oxydschicht überzogen ist. Die Kapazität dieses Kondensators ist jedoch nicht bestimmt durch den Abstand der gegenübergestellten Elektroden, sondern durch die Dicke der Sperrschicht auf der Anode und der Oberfläche der Anode. Um nun bei Durchschlägen der dielektrischen Schicht ein Regenerieren des Kondensators ähnlich wie bei den bekannten elektrolytischen Kondensatoren zu ermöglichen, wird ein solches elektrisch leitendes Gas verwendet, das mit dem Ventilmetall der ersten Belegung eine chemische Verbindung eingeht, die die Eigenschaft einer dielektrischen Sperrschicht besitzt. Ein derartiges Gas ist z. B. Sauerstoff, das mit Aluminium als Ventilmetall das gute dielektrische Eigenschaften besitzende Aluminiumoxyd bildet. Das Gas muß, um die notwendige Leitfähigkeit zu erhalten, stark verdünnt sein. Die Ionisation des Gases kann in verschiedenster Weise erfolgen, z. B. durch Stoßionisation oder unter Benutzung heißer Metalle als Kathode.By the condenser. according to the invention is now also a gas-filled tube is used, the anode of which consists of a valve metal, which with is coated with a non-conductive dielectric oxide layer. The capacity of this However, the capacitor is not determined by the spacing of the opposed Electrodes, but by the thickness of the barrier layer on the anode and the surface the anode. In order to regenerate if the dielectric layer breaks down of the capacitor similar to the known electrolytic capacitors allow, such an electrically conductive gas is used, which with the valve metal the first assignment a chemical compound is formed, which has the property of a dielectric barrier layer. Such a gas is e.g. B. Oxygen, that with aluminum as the valve metal, aluminum oxide has good dielectric properties forms. In order to obtain the necessary conductivity, the gas must be highly diluted be. the Ionization of the gas can take place in various ways, z. B. by impact ionization or using hot metals as cathodes.
