Description

. Bewehrung für Einleiterwechselstromkabel. Zusatz zum Patent 453848. Die vorliegende Erfindung betrifft eine weitere Ausbildung der in dem Hauptpatent vorgeschlagenen Mittel zur Verminderung der Induktionsströme in der Bewehrung von Einleiterwechselstronika.beln, nämlich der Einschaltung von Wechselstromwiderständen in die Bewehrung. Sie benutzt die Tatsache, daß die in der Bewehrung induzierte Spannung proportional mit der Länge des Kabels zunimmt, und daß deshalb bei Aufteilung der Bewehrung in einzelne voneinander isolierte Längenabschnitte die in diesen induzierten Teilspannungen um so kleiner sind, je kürzer die Abschnitte sind. Sind die Abschnitte kurz genug, so bleiben die in ihnen induzierten Teilspannungen unterhalb derjenigen Grenze, bei welcher die aus der Bewehrung durch die Jutebewickiung in die Erde dringenden Ströme zu Störungen Anlaß geben können. Um dieses Ziel zu erreichen, genügt meist die Unterteilung der Bewehrung einer Fabrikationslänge des Kabels in zwei voneinander isolierte Unterabschnitte. In jedem Falle soll aber nach der Erfindung die Zahl der Unterabschnitte, in welche die Bewehrung jeder Fabrikationslänge des Kabels zerteilt wird, so groß gemacht werden, daß schädliche Störungsströme nicht mehr auftreten.. Armouring for single-core AC cables. Addendum to patent 453848. The present invention relates to a further embodiment of that in the main patent proposed means of reducing the induction currents in the reinforcement of Einleiterwechselstronika.beln, namely the switching on of alternating current resistors into the reinforcement. It uses the fact that it is induced in the reinforcement Voltage increases proportionally with the length of the cable and that is why it is split of the reinforcement into individual lengths that are isolated from each other Partial voltages are smaller, the shorter the sections are. Are the sections short enough, the partial voltages induced in them remain below those Limit at which those from the reinforcement penetrate into the earth through the jute wrapping Currents can give rise to disturbances. In order to achieve this goal, it is usually enough the division of the armouring of a manufacturing length of the cable into two of each other isolated subsections. In any case, however, according to the invention, the number the subsections in which the armouring of each fabrication length of the cable is divided, made so large that harmful interference currents are no longer appear.

Urr, den Isolationswiderstand an den Trennstellen dauernd genügend hoch zu halten, wird die Trennstelle mit einer Schicht isolierender Vergußmasse umgeben, über der zum Schutze des Kabels ein beispielsweise aus zwei Hälften bestehender Muffenmantel aufgebracht wird.Urr, the insulation resistance at the separation points is always sufficient To keep it high, the separation point is covered with a layer of insulating potting compound surrounded, over which to protect the cable, for example, consisting of two halves Sleeve jacket is applied.
