Description
Als Anzeigevorrichtung, insbesondere bei Isolationsprüfungen dienende Edelgasglimmröhre. Die bekannten Glimmröhren für Isolationsmessungen sind entweder nur für Gleichstrom oder nur lür Wechselstrom zu benutzen. Insbesondere sind die bekannten stiftförmigen Anoden nicht empfindlich genug.Serving as a display device, especially for insulation tests Noble gas glow tube. The known glow tubes for insulation measurements are either to be used only for direct current or only for alternating current. In particular, they are known pin-shaped anodes are not sensitive enough.
Gegenstand der Erfindung ist eine Edelgasglimmröhre, bei der eine möglichst große Empfindlichkeit, eine geradlinige Charakteristik und eine gleich gute Verwendungsmöglichkeit sowohl für Gleich- als auch für Wechselstrom vereinigt sind.The invention relates to a noble gas glow tube in which a the greatest possible sensitivity, a straight line characteristic and one the same good use for both direct and alternating current combined are.
Zu diesem Zwecke ist die Anode ; u einem Rahmen ausgebildet, der in sich geschlossen ist und möglichst nahe an der Kathode liegt.For this purpose the anode is; u formed a frame that is in is closed and as close as possible to the cathode.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes, und zwar Fig. i die Charakteristik einer Glimmröhre mit rahmenförmiger Anode und Fig. 2 die Glimmröhre selbst.The drawing shows an embodiment of the subject matter of the invention, namely Fig. i the characteristics of a glow tube with a frame-shaped anode and Fig. 2 shows the glow tube itself.
Die etwa zylinderförmige Glimmröhre enthält eine Anode 2, die z. B. rechteckig geformt und so bemessen ist, daß ihre der Glimmröhrenwand parallel liegendenRahmeni c ile möglichst nahe an der die Kathode bilc;enden Glimmröhrenwand anliegen. Wie das Schaubild Fig. i erkennen läßt, zeigen die positive und negative Charakteristik nur geringe Abweichungen. Trotzdem springt die Lampe bereits bei 81 Volt Spannung an. Die geradlinige Charakteristik ist erforderlich, um unmittelbar aus der Stärke des Aufleuchtens der Röhre den Isolationszustand zu erkennen.The approximately cylindrical glow tube contains an anode 2, the z. B. is rectangular in shape and dimensioned so that its frame lying parallel to the glow tube wall c ile rest as close as possible to the glow tube wall forming the cathode. As the diagram in FIG. i shows the positive and negative characteristics only minor deviations. Nevertheless, the lamp jumps at a voltage of 81 volts at. The straightforward characteristic is required to immediately come out of the strength when the tube lights up to recognize the state of the insulation.
Die durch die Rahmenform der Anode ermöglichte starke und vor allem gleichmäßige Leuchtkraft macht die Glimmröhre auch für Beleuchtungszwecke verwendbar.The strong and above all made possible by the frame shape of the anode Uniform luminosity makes the glow tube also suitable for lighting purposes.
