Description

Verfahren zur Herstellung isolierender, Papier enthaltender Schichten verschiedener Dielektrizitätskonstante Die Erfindung betrifft ein Verfahren zur Herstellung isolierender Schichten verschiedener Dielektrizitätskonstante zu dem an sich bekannten Zwecke, in inhomogenen elektrischen Feldern die auf die ScYichten höherer Dielektrizitätskonstante entfallenden Teilspannungen zu vermindern, wodurch eine Ersparnis an Gesamtisolation ermöglicht wird, wenn in der Richtung abnehmbarer elektrischer Feldstärke die Ordnung der Schichten nach abnehmenden Dielektrizitätskonstanten erfolgt. Die getränkte Papierisolation von Hochspannungskabeln sowie von ihren Verbindungsmuffen und Endverschlüssen bildet ein besonders wichtiges Anwendungsgebiet der Erfindung.Process for the production of insulating layers containing paper different dielectric constant The invention relates to a method for Production of insulating layers of different dielectric constants to the purposes known per se, in inhomogeneous electric fields that affect the scYichten higher dielectric constant to reduce omitted partial voltages, whereby a saving in overall insulation is made possible if detachable in the direction electric field strength the order of the layers according to decreasing dielectric constant he follows. The impregnated paper insulation of high-voltage cables and their connection sleeves and terminations is a particularly important field of application of the invention.

Wir haben festgestellt, daß die Dielektrizitätskonstante von mit Isoliermasse getränkter Papierisolation um so größer wird, je mehr das Raumgewicht des verwendeten Papiers durch Walzen unter Druck oder andere Preßmittel gesteigert wird.We have found that the dielectric constant of with insulating compound Soaked paper insulation becomes larger, the more the density of the used Paper is increased by rolling under pressure or other pressing means.

Erfindungsgemäß werden daher isolierende, Papier enthaltende Schichten verschiedener Dielektrizitätskonstante innerhalb der Leiterisolation in der Weise hergestellt, daß die Staffelung der Dielektrizitätskonstante durch entsprechende, durch Walzen unter Druck oder andere Preßmittel erzeugte Staffelung des Raumgewichtes des Isolierpapiers erreicht wird.According to the invention, therefore, insulating layers containing paper are used different dielectric constant within the conductor insulation in the way established that the grading of the dielectric constant by appropriate, Graduation of the density produced by rolling under pressure or other pressing means of the insulating paper is achieved.

Die Isolation von Hochspannungskabeln, Verbindungsmuffen und Endverschlüssen wird gemäß der Erfindung derart hergestellt, daß die Dielektrizitätskonstante des Isolierpapiers durch !, Erhöhung seines Raumgewichtes durch Walzen unter Druck oder andere Preßmittel um so mehr gesteigert wird, je näher die betreffende Schicht dem Stromleiter liegt.The insulation of high voltage cables, connection sleeves and terminations is produced according to the invention such that the dielectric constant of the Insulating paper by!, Increasing its density by rolling under pressure or other pressing means is increased the closer the layer in question to this Conductor lies.
