Description

Überspannnngsableiter Es ist bekannt, als überspannungsableiter Glimmröhren zu verwenden. Diese Glimmröhren haben jedoch den großen Nachteil, daß sie verhältnismäßig empfindlich gegenmechanische oder thermische Einflüsse sind, da sie, wenigstens zum Teil, aus Glas bestehen oder einzelne Teile durch einen Glasfluß miteinander verbunden sind. Ein weiterer Nachteil ist ihre Größe.Surge arrester It is known as glow tube surge arrester to use. However, these glow tubes have the major disadvantage that they are relatively are sensitive to mechanical or thermal influences because they are, at least partly, made of glass or individual parts together by a glass flow are connected. Another disadvantage is their size.

Die erwähnten Nachteile werden durch die vorliegende Erfindung vermieden. Gemäß der Erfindung besteht ein überspannungsableiter aus einer Glimmröhre, die unter Vermeidung von Glas ausschließlich aus metallischen und keramischen Teilen besteht, die miteinander verlötet sind.The disadvantages mentioned are avoided by the present invention. According to the invention, a surge arrester consists of a glow tube that while avoiding glass made exclusively of metallic and ceramic parts exists that are soldered together.

Der Vorteil einer solchen Ausführung besteht, wie eingangs schon gesagt, darin, da13 Glimmröhren aus metallischen oder keramischen Werkstoffen verhältnismäßig kleine Abmessungen haben können. Es ist zwar bekannt, für die Herstellung von Glimmröhren keramische Werkstoffe zu benutzen, indessen wurde bisher bei allen derartigen Konstruktionen zur Abdichtung Glas verwendet, wodurch sich wieder in mechanischer und thermischer Beziehung Mängel ergaben-In der Figur ist ein überspannungsableiter nach der Erfindung beispielsweise dargestellt. Die Wandung des Entladungsgefäßes bildet ein keramisches Rohr i, welches durch zwei Kappen 2 und 3 vakuumdicht verschlossen ist. Die Kappe 3 trägt einen Pumpstutzen q., welcher beispielsweise bei 5 in die. Kappe @eingelötet ist. In das Rohr hinein ragen zwei Elektroden 6 und 7. Die Elektrode 7 ist als Stab ausgebildet und von der zylinderförmigen Elektrode 6 konzentrisch umgeben. Zur Zentrierung der Elektrode 6 werden Haltenasen i o verwendet; für den genannten Zweck kann aber auch der untere Rand der Elektrode 6 nach der Gefäßwand zu umgebogen werden. Die Befestigung der Elektroden erfolgt durch die Kappen 2 und 3. Diese sind unter Verwendung einer metallischen Zwischen.scbicht i i auf das keramische Rohr i aufgelötet. Die Verlötung der Kappen mit dem keramischen Rohr i bzw. der vorher aufgebrachten Metallunterlage i i erfolgt zweckmäßig dadurch, daß man beim Herstellungsprozeß einen Ring 12 aus Lötmaterial, beispielsweise aus Silber, einlegt, der bei Erhitzung eine sichere Verlötung gewährleistet. Um ein Wegfließen. des. Lobes in das Innere des G.efäß,es zu verhüten, ist der Ring aus Lötmaterial zwischen die Kappe 2 bzw. 3 einerseits und die Zwischenscheiben 13 bzw. 1q. anderseits eingelegt. Beim. Flüssigwerden muß das Lot also in die Fugen 15 eindringen.The advantage of such a design is, as already mentioned at the beginning, that glow tubes made of metallic or ceramic materials can have relatively small dimensions. Although it is known to use ceramic materials for the production of glow tubes, glass has hitherto been used for sealing in all such constructions, which again resulted in deficiencies in mechanical and thermal relationships. The wall of the discharge vessel forms a ceramic tube i, which is closed in a vacuum-tight manner by two caps 2 and 3. The cap 3 carries a pump nozzle q. Which, for example, at 5 in the. Cap @ is soldered in. Two electrodes 6 and 7 protrude into the tube. The electrode 7 is designed as a rod and is concentrically surrounded by the cylindrical electrode 6. Retaining lugs io are used to center the electrode 6; for the stated purpose, however, the lower edge of the electrode 6 can also be bent over towards the vessel wall. The electrodes are attached by the caps 2 and 3. These are soldered onto the ceramic tube i using a metallic intermediate layer ii. The soldering of the caps to the ceramic tube i or the previously applied metal base ii is expediently carried out by inserting a ring 12 made of soldering material, for example silver, during the manufacturing process, which ensures secure soldering when heated. To a flow away. des. Praise to the inside of the G.evessel, to prevent it, is the ring made of soldering material between the cap 2 or 3 on the one hand and the washers 13 or 1q. inserted on the other hand. At the. Liquefaction the solder must therefore penetrate the joints 1. 5

Das Auflöten der Kappen 2 und 3 kann gleichzeitig mit dem Einlöten des Pumpstutzens q. in die Kappe 3 erfolgen, so daß nur eineinziger Lötpr ozeß notwendig ist.The soldering of the caps 2 and 3 can be done at the same time as the soldering of the pump nozzle q. take place in the cap 3, so that only a single soldering process is necessary is.

überspannungsableiter nach der Erfindung erweisen sich als äußerst robust, da bei ihrer Herstellung die mechanisch und thermisch verhältnismäßig schwachen Glasbeile vermieden sind. Sie können daher mit Vorteil überall dort verwendet werden, wo hohe mechanische oder thermische Beanspruchungen zu erwarten sind.Surge arresters according to the invention prove to be extremely robust, since they are mechanically and thermally relatively weak in their manufacture Glass hatchets are avoided. They can therefore be used with advantage anywhere where high mechanical or thermal loads are to be expected.
