DEUTSCHESGERMAN
Die Erfindung betrifft ein Verfahren zur Herstellung eines gasgefüllten pumpstengellosen Entladungsgefäßes, insbesondere eines Ein- oder Mehrstreckenüberspannungsableiters. The invention relates to a method for producing a gas-filled pump stem-free discharge vessel, in particular a single or multi-section surge arrester.
Es ist bekannt, daß man Entladungsgefäße in einer Vakuumkammer evakuiert, die Kammer mit Edelgas eines gewählten Druckes füllt und das Entladungsgefäß durch Löten oder Verschmelzen in der Vakuumkammer schließt. Aufgabe der Erfindung ist es, dieses verhältnismäßig umständliche Verfahren zu vereinfachen. Erfindungsgemäß wird dazu vorgeschlagen, daß das Füllgas auf einer Temperatur gehalten wird, bei der die thermische Ausdehnung des Füllgases im Moment des vakuumdichten Verschließ ens des Entladungsgefäßes so hoch ist, daß nach dem Erkalten im Entladungsgefäß der geforderte Unterdruck herrscht.It is known that discharge vessels are evacuated in a vacuum chamber, the chamber with noble gas a selected pressure and fills the discharge vessel by soldering or fusing in the vacuum chamber closes. The object of the invention is to simplify this relatively cumbersome method. According to the invention it is proposed that the filling gas is kept at a temperature in which the thermal expansion of the filling gas at the moment of the vacuum-tight closure of the discharge vessel is so high that the required negative pressure prevails in the discharge vessel after cooling.
Das Verfahren wird nachfolgend an Hand der Fig. 1 näher erläutert:The method is explained in more detail below with reference to FIG. 1:
Dort befindet sich in der Einschmelzkammer 1 ein Einstreckenüberspannungsableiter, der aus den beiden Elektroden 2 und 3 sowie dem zwischen diesen Elektroden angeordneten Isolierkörper 4 besteht. Durch die Teile 5 und 6 wird der zusammengesteckte Überspannungsableiter zusammengehalten. Während des Einschmelzvorganges strömt durch den Einlaß 7 das Füllgas, z. B. Argon, mit etwa Atmosphärendruck durch die Einschmelzkammer 1. Um die Elektroden des Überspannungsabieiters mit dem Keramikkörper 4 zu verbinden, werden die Elektroden durch die Hochfrequenzspule 8 erhitzt. Die erhitzten Teile des Überspannungsableiters erhitzen ihrerseits das Füllgas. Die Temperatur der erhitzten Teile des Überspannungsableiters wird dabei so gewählt, daß das Füllgas seinerseits auf die gewünschte Temperatur gebracht wird. Bekanntlich beträgt nach dem Gasgesetz die Ausdehnung des Gases V2-3 des Volumens pro Grad der Erwärmung, und daraus errechnet sich dann der im fertiggestellten Entladungsgefäß herrschende Gasdruck. Durch den Wegfall kostspieliger Evakuierungseinrichtungen ist die zu dem vorgeschlagenen Ver- fahren benötigte Einschmelzvorrichtung relativ einfach, und die Investierungskosten sind gering.There is a single-section surge arrester in the melting chamber 1, which consists of the two Electrodes 2 and 3 and the insulating body 4 arranged between these electrodes. By parts 5 and 6, the assembled surge arrester is held together. During the Melting process flows through the inlet 7, the filling gas, for. B. argon, at about atmospheric pressure through the melting chamber 1. To connect the electrodes of the surge arrester with the ceramic body 4 To connect, the electrodes are heated by the high frequency coil 8. The heated parts of the surge arrester in turn heat the filling gas. The temperature of the heated parts of the surge arrester is chosen so that the filling gas in turn is brought to the desired temperature will. As is known, according to the gas law, the expansion of the gas is V2-3 of the volume per degree the heating, and the gas pressure in the completed discharge vessel is then calculated from this. The elimination of costly evacuation facilities means that the proposed drive the melting device required relatively easily, and the investment costs are low.
Ein fertiger Überspannungsableiter ist in Fig. 2 noch einmal deutlich dargestellt. Das erfindungsgemäße Verfahren eignet sich jedoch nicht nur zur Herstellung von Einstreckenüberspannungsableitern, sondern in gleicher Weise z. B. zur Herstellung von Verfahren zur HerstellungA finished surge arrester is clearly shown again in FIG. The inventive However, the process is not only suitable for the manufacture of single-section surge arresters, but in the same way z. B. for the production of methods of production

Zweistreckenüberspannungsableitern, von denen einer in Fig. 3 dargestellt ist. Die Erfindung beschränkt sich auch nicht darauf, daß die Erwärmung des Füllgases durch Teile des Entladungsgefäßes selbst erfolgt, sie verlangt lediglich, daß das im Augenblick des vakuumdichten Verschließens vorhandene Füllgas die Temperatur aufweist, die nach dem Erkalten den geforderten Unterdruck im Gefäß ergibt.Two-line surge arresters, one of which is shown in FIG. The invention is limited also do not insist that the filling gas is heated by parts of the discharge vessel itself, it only requires that the filling gas present at the moment of the vacuum-tight closing has the temperature that results in the required negative pressure in the vessel after cooling.
