Description

Die Erfindung betrifft den Aufbau der Isolierung von .Ein- oder Mehrleiterhochspannungsdruckkabeln, die im Innern zwecks Steigerung der Dauerdurchschlags- und Temperaturfestigkeit mit leiaem unter statischem Druck stehenden Gas gefüllt sind. Bd. diesen Kabeln dient das Druckmittel zusammen, mit aufgewickelten Papierstreifen auch als Isoliefmittel an Stelle der bisher verwendeten visoosien Öle oder Ölgemische. Die Schwierigkeiten bei diesen Ausführungen bestehen nun darin, daß bei liohien Spannungen 'und Drücken an den Rändern der mit Zwischenräumen aufgewickelten Papierstreifen FeId-Verzerrungen auftreten, deren Ursachen in der Verschiedenheit der Dielektrizitätskonstanten zwischen Papier und Preßgas zu suchen sind. Durchschlage der in der Schichtrichtung an und für sich wenig widerstandsfäMgen Papierisolierung sind daher die zwangsläufige Folge.The invention relates to the construction of the insulation of .Single or multi-conductor high-voltage pressure cables, the inside for the purpose of increasing the permanent dielectric strength and temperature resistance with leiaem under static Pressurized gas are filled. Bd. These cables are used together with the pressure medium rolled up paper strips can also be used as insulating media instead of the previously used visoosien oils or oil mixtures. Difficulties in these explanations consist in the fact that with liohien tensions' and Pressing on the edges of the paper strips wound with spaces in between field distortions occur, the causes of which are the difference in the dielectric constants are to be looked for between paper and compressed gas. Penetration in the direction of the layers Paper insulation that is inherently less resistant is therefore the inevitable consequence.

Zur Vermeidung dieses Übelstandes werden erfindungsgemäß die Ränder der Papierstreifen beiderseitig nach innen umgebogen, wodurch die Kanten abgeschirmt und die ungünstigen Feldverzerrungen . !Herabgesetzt werden.To avoid this inconvenience, the edges of the paper strips are according to the invention bent inwards on both sides, which shields the edges and the unfavorable ones Field distortions. ! Be reduced.

In der Zeichnung ist eine Ausführungsform des neuen Hochspannungsfcabels in Längs- und Querschnitt dargestellt.In the drawing, an embodiment of the new high voltage cable is shown in FIG Shown longitudinal and cross-section.

Um die Kupferleiter 4 sind satinierte Papierstreifen 5, denen beide Rändler 7 nach innen umgebogen sind, bis zur vorgeschriebenen Stärke derart aufgewickelt, daß sie sich nicht überlappen oder Stoß an Stoß liegen, sondern absichtlich in größeren Zwischenräumen voneinander aufgebracht sind und mit dem jeweils darüberfolgenden Papierstreifen je Hohlräume 6 bilden.There are satined paper strips around the copper conductors 4 5, where both margins 7 are bent inwards, up to the prescribed Thickness wound in such a way that they do not overlap or are butt to butt, but are intentionally applied in larger spaces from each other and with each subsequent paper strip form cavities 6.
