Description

Verfahren zur Herstellung einer Hochspannungsd'ruckkabelanlage ein- oder mehradriger Ausführung Zusatz zum Patent 701 4o8 Gegenstand des Hauptpatents ist eine Hochspannungsdruckkabelanlage ein- oder mehradriger Ausführung, bei der -die Aderisolation durch eine genügend undurchlässige und genügend geschmeidige Schicht, z. B. aus Blei, von dem vorn außen auf sie wirkenden, innerhalb einer druckfesten Außenhülle untergebrachten, unter einem bestimmten, durch besondere Mittelerzeugten Druck gehaltenen. gasförmigen oder flüssigen Druckmittel getrennt ist. Diese Anlage ist dadurch gekennzeichnet, daß die Außenhülle aus deiner Rohrleitung aus druckfestem Werkstoff, wie Stahl, besteht, in die die KabielseeleUseeingelegt ist.A method for producing a one- or multi-core embodiment Hochspannungsd'ruckkabelanlage additional patent 701 4o8 subject of the main patent is a high-voltage cable system pressure single- or multi-core embodiment in which -the core insulation by a sufficiently impermeable and sufficiently smooth layer such. B. made of lead, from the front outside acting on them, housed within a pressure-resistant outer shell, held under a certain pressure generated by special means. gaseous or liquid pressure medium is separated. This system is characterized in that the outer shell consists of your pipeline made of pressure-resistant material, such as steel, into which the cable core is inserted.

Während nun die Kabelseele bei ,genÜgender Dicke des Bleimantels gefahrlos in geradlinige Rohre eingezogen werden kann, kann sie beim Einziehen in Rohre, die mit Krümmungen versehen sind, beschädigt werden.While now the cable core with sufficient thickness of the lead sheath is safe can be drawn into straight pipes, it can when drawn into pipes that are curved.

Dies wird gemäß der vorliegenden Erfindung dadurch vermieden, daß lan den Kriimmungen mehrteilige ;gekrümmte Rohrstücke erst nach dem Verlegen der geraden Rohre und nach denn Einziehen der Kabelseele in die verlegten Rohre um die Seele gelegt und darauf druckfest mit den Rohren verbunden werden.This is avoided according to the present invention in that Multi-part curved pipe sections on the bends only after the laying of the straight pipes and then pulling the cable core into the laid pipes around the The core is placed and connected to the pipes in a pressure-proof manner.

An den Krümmungsstelllen fehlen also zunächst die Rohrstücke. Die Kabelseele wird zuerst in die geraden Rohre eingezogen, in den Krümmungen in bekannter Weise von Hand oder über Rollen vorsichtig weitergeführt und dann 'm die folgende gerade Rohrstrecke weiter eingezogen usw. Erst nach dem Einziehen werden daraufhin die einzelnen Rohrkrümmungen in der Weisse fertiggestellt, daß zwischen den Enden zweier gerader Rohre ein mehrteiliges, beispielsweise aus zwei Teilen bestehendes Rohrstück um die Kabelseele gelegt wird und die Enden -der Rohrkrümmungen mit dien geradlinig verlaufenden Rohren und die Teile der Rohrkrümmungen selbst so. verbunden werden, daß die Trennfugien völlig druckfest und undurchlässig für das Druckmittel sind. Die Verbindung der Trennfugen kann bei Verwendung von Stahlmohren zweckmäßig durch Verschweißung geschehen. Beschädigungen der Kabelseele können hierbei beispielsweise durch Umwickeln der betreffenden Stelle mit Asbest vermieden werden.So initially the pipe pieces are missing at the points of curvature. the Cable core is first drawn into the straight pipes, in the bends in a more familiar way Carefully continued by hand or by means of rollers and then the following straight pipe section continues to be pulled in, etc. Only after pulling in are thereupon the individual pipe bends in the white finished that between the ends two straight tubes a multi-part, for example consisting of two parts Pipe piece is placed around the cable core and the ends of the pipe bends with dien straight pipes and the parts of the pipe bends themselves so. tied together that the parting joints are completely pressure-resistant and impermeable to the pressure medium are. The connection of the parting lines can be useful when using steel carrots done by welding. Damage to the cable core can for example by wrapping asbestos around the affected area.
