Description

Der Verwendung der nach dem bisherigen Verfahren gebauten Kondensatorklemmen für besonders hohe Spannungen wird durch die Schwierigkeit der Beschaffung der hierzu erforderlichen .Papierbreite eine Grenze gesetzt. Zweck der Erfindung ist, diese Grenze ohne weitere Verbreiterung des notwendigen Papierstreifens höher zu rücken.The use of the capacitor terminals built according to the previous method for special high tension is required by the difficulty of obtaining the required for this .Paper width set a limit. The purpose of the invention is to avoid this limit further widening of the necessary paper strip to move higher.

Zu diesem Zweck sollen erfindungsgemäß ίο zwei Kondensatoren α (Abb. i) durch geeignete Verbindung zu einer einzigen Kondensatorklemme doppelter Länge vereinigt werden.For this purpose, according to the invention, two capacitors α (Fig. I) are to be combined into a single capacitor terminal of double length by suitable connection.

Die Verbindung der beiden Einzelklemmen geschieht erfindungsgemäß derart, daß an den einander zugekehrten Teilen die Metallbeläge unter Berücksichtigungdes erforderlu henKriechweges von Belag zu Belag freigelegt und die Beläge b, c, d (Abb. 2 und 3) gleichen Potentials durch konzentrische Metallzylinder e, f, g(Abb. 2 und 3) elektrisch verbunden werden. Dabei ist es wesentlich, daß zwischen zwei aufeinanderfolgenden Metallzylindern Kriechwege von genügender Länge vorhanden sind. Zu diesem Zwecke werden nach Abb. 2 die Verbindungszylinder e, f, g der Metallbelege b, c, d im inneren Durchmesser größer gehalten als die Belege selbst. Von einem Belag zum anderen besteht dann nicht nur der kurze radiale Kriechweg h, sondern außerdem der achsiale Kriechweg i. According to the invention, the two individual clamps are connected in such a way that, on the parts facing each other, the metal coatings are exposed, taking into account the required creepage path from coating to coating, and coatings b, c, d (Figs. 2 and 3) have the same potential through concentric metal cylinders e, f, g (Fig. 2 and 3) are electrically connected. It is essential that there are creepage paths of sufficient length between two successive metal cylinders. For this purpose, are based on Fig. 2, the connecting cylinder e, f, the metal evidence g b, c, d in inner diameter held greater than the documents themselves. From a lining on the other hand, there is then not H, only the short radial leakage path, but also the axial creepage distance i.

Der gleiche Zweck kann erreicht werden, wenn man die Durchführung nach Abb. 3 ausführt. Dabei entfernt sich nicht, wie in Abb. 2, der Metallzylinder f nach außen von der Kriechfläche i, sondern die Kriechfläche k (Abb. 3) entfernt sich umgekehrt nach innen vom Metallzylinder f. The same purpose can be achieved by performing the procedure shown in Fig. 3. As in Fig. 2, the metal cylinder f does not move outwards from the creeping surface i, but rather the creeping surface k (Fig. 3), conversely, moves away inwards from the metal cylinder f.

Die Verbindung der beiden Hälften a, a (Abb. 1) einer Doppelklemme erfolgt durch einen in der Mitte durchlaufenden Leiter 1 (Abb. i, 2, 3) und außerdem durch eine Verbindungsmuffe m (Abb. 1). Der Raum η zwischen Muffe m und Klemme α, α ist mit Öl gefüllt, dessen Durchlaß durch Öffnungen 0 (Abb. 2, 3) in den Metallzylindern e, f, g erleichtert werden kann. An dem Ölraum ist ein Ausdehnungsgefäß angeschlossen (in den Abbildungen nicht eigens aufgeführt), so daß man mit hochwertiger Isolierung und kurzen Kriechwegen rechnen kann. Der mittlere durch die Muffe eingeschlossene Teil der Durchführung soll deshalb höchstens x/3 der Gesamtlänge ausmachen. Mehrere zu einem Apparat oder zu einer Apparat gruppe gehörigen Klemmen können mit einem einzigen Ausdehnungsgefäß versehen sein.The two halves a, a (Fig. 1) of a double clamp are connected by a conductor 1 running through the middle (Fig. I, 2, 3) and also by a connecting sleeve m (Fig. 1). The space η between the sleeve m and the terminal α, α is filled with oil, the passage of which can be facilitated through openings 0 (Fig. 2, 3) in the metal cylinders e, f, g. An expansion tank is connected to the oil chamber (not specifically shown in the figures) so that high-quality insulation and short creepage distances can be expected. The middle part of the bushing enclosed by the socket should therefore be at most x / 3 of the total length. Several clamps belonging to an apparatus or group of apparatuses can be provided with a single expansion vessel.
