Description
Durchführungsisolator nach dem Kondensatorprinzip. Die Verwendung des Kondensatorprinzips zur Herstellung von Durchführungsisolatoren an sich ist bekannt. Diese Anordnung besitzt aber die Nachteile aller Isolatoren mit festem Isoliermittel, dass bei Verletzung des Materials durch elektrische Beanspruchung an irgend einer Stelle ein dauernd geschwächter Punkt des Isoliermittels, bezw. des Dielektrikums geschaffen wird. Weiter weist dieselbe groben dielektrischen Verschiebungsfluss und dadurch hohe Beanspruchung der Luft am Flansch auf.
Zweck der vorliegenden Erfindung ist, diese Nachteile zu vermeiden, dadurch, dass Luft oder ein anderes Gas mit kleiner Dielek- trizitätskonstante, z. B. Stickstoff, als Dielek- trikum verwendet ist. Dabei kann Luft als Dielektrikum mit der Aussenluft in Verbin dung stehen oder von derselben abgeschlossen sein.
In der Zeichnung sind beispielsweise Aus führungsformen des Erfindungsgegenstandes schematisch dargestellt. Überall kommt festes Isoliermaterial nur als mechanischer Träger n Anwendung. Die eigentliche Isolation, bezw. das Dielektrikuin wird durch Luft oder ein anderes Gras mit kleiner Dielektrizitäts- konstante dargestellt.
Fig. 1 zeigt den Leiter b, welcher durch den Flansch a hindurchgeführt ist. Nach dem Kondensatorprinzip wird die gleichmässige elektrische Beanspruchung des Dielektrikums Luft durch eine Reihe konzentrischer Zylin der c, d bewirkt, welche durch Stücke aus Isoliermaterial e distanziert werden. Es ist eine solche Formgebung des Isolators zu empfehlen, dass ein Überschlag aussen und nicht im Innern des Isolators stattfindet.
Fig. 2 zeigt eine Anordnung, wo die Iso- lierstücke e als Zylinder ausgebildet sind. Auch hier ist Luft elektrisch beanspruchtes Isolationsmaterial, bezw. Dielektrikum.
Bushing insulator based on the capacitor principle. The use of the capacitor principle for the production of bushing insulators is known per se. However, this arrangement has the disadvantages of all insulators with solid insulating means that if the material is damaged by electrical stress at any point a permanently weakened point of the insulating means, respectively. of the dielectric is created. Furthermore, the same has a coarse dielectric displacement flux and thus high stress on the air on the flange.
The purpose of the present invention is to avoid these disadvantages by using air or another gas with a low dielectric constant, e.g. B. nitrogen, is used as a dielectric. Air as a dielectric can be in connection with the outside air or be closed off by the same.
In the drawing, for example, embodiments of the subject invention are shown schematically. Solid insulating material is used everywhere only as a mechanical carrier. The actual isolation, respectively. the dielectric is represented by air or some other grass with a low dielectric constant.
Fig. 1 shows the conductor b, which is passed through the flange a. According to the capacitor principle, the even electrical stress on the dielectric air is caused by a series of concentric cylinders c, d, which are separated by pieces of insulating material e. It is recommended that the isolator be shaped so that flashover occurs outside and not inside the isolator.
2 shows an arrangement where the insulating pieces e are designed as cylinders. Here, too, air is electrically stressed insulation material, respectively. Dielectric.
