Starkstromkabel mit Steuerleieungen zum Überwachen und Schalten von StarkstromnetzenPower cable with control lines for monitoring and Switching of power networks
Die Erfindung betrifft ein Starkstromkabel, insbesondere in Netzen der Mittel- und Hochspannungsebene, mit in den Zwickeln der isolierten Energieleiter angeordneten elektrischen Steuer- gPi leitungen zum überwachen und Schalten von Starkstromnetzen. The invention relates to a power cable , in particular in networks of the medium and high voltage level, with electrical control gPi lines arranged in the interstices of the insulated energy conductor for monitoring and switching power networks.
Die Entwicklung in der Energieübertragungstechnik zu höheren Übertragungsleistungen erhöht immer mehr den Störpegel der Steuerleitungen. Dies trifft vorwiegend bei Starkstromnetzen der Mittel- und Hochspannungsebene, welche häufig in der Erde verlegt sind, zu, wo diese Hilfsleitungen, isoliert in den Zwickeln der Phasenleitungen angeordnet, mit den Phasenleitern zu einem Kabel vereinigt sind. Hierbei dienen diese Hilfsleitungen dazu, die einzelnen Umspannwerke mittels Fernwirkeinrichtungen zu überwachen und zu schalten. Besonders kritischThe development in energy transmission technology to higher transmission capacities is increasing the interference level of the Control lines. This mainly applies to power grids of the medium and high voltage level, which are often in the earth are laid to where these auxiliary lines, insulated in the interstices of the phase lines, with the phase conductors are combined into one cable. These auxiliary lines serve to connect the individual substations by means of telecontrol devices to monitor and switch. Particularly critical

sind Kurzschlüsse im Energienetz, weil sie einerseits zu hohen Störeinflüssen in den Steuerleitungen führen andererseits aber gerade in diesen Momenten Schaltbefehle über diese Leitungen störungsfrei übertragen werden müssen. Weiterhin wirkt sich erschwerend der Hang zu Kunststoff-isolierten Starkstromkabeln aus, deren nicht abgeschirmte Adern elektromagnetische Störwellen ungehindert abstrahlen. Umso höher muß der Aufwand zum Schutz der Steuerleitungen getrieben werden.are short circuits in the energy network because they lead to high levels of interference in the control lines on the one hand, but on the other It is precisely at these moments that switching commands have to be transmitted over these lines without interference. Furthermore affects aggravating the tendency to plastic-insulated power cables, whose unshielded cores generate electromagnetic interference waves radiate unhindered. The more effort must be made to protect the control lines.
Jedoch werden bei erhöhtem Aufwand an Abschirmmitteln die Grenzen des wirtschaftlich Vertretbaren bald erreicht. Aber auch die hierbei zu erwartende Querschnittsvergrößerung und Gewichtszu-V-V nähme des Kabels als Folge der metallischen Abschirmung kann eine Beschränkung in diesen Eigenschaften auferlegen, weil diese Kabelgrößen zumeist nach oben begrenzt sind.However, with increased expenditure on shielding means, the limits of what is economically viable will soon be reached. But also the here to be expected increase in cross-section and weight to V-V taking of the cable as a result of the metallic shielding can impose a limitation in these properties because of this Cable sizes are mostly limited upwards.
Die Aufgabe der Erfindung ist es, ein Starkstromkabel der eingangs genannten Art zu schaffen, welches auch bei höchsten elektrisch zu übertragenden Leistungen und bei eingeschränkten mechanischen Kabeleigenschaften vollkommene elektrische Störfreiheit der Steuerleitungen gewährleistet.The object of the invention is to provide a power cable of the opening to create mentioned type, which also with the highest electrical power to be transmitted and with limited mechanical Cable properties guarantee that the control lines are completely free of electrical interference.
Erfindungsgemäß sind die Steuerleitungen aus Lichtleitfasern aufgebaut. Hierbei können die Lichtleitfasern von einer Schutz- f~\ hülle umgeben sein.According to the invention, the control lines are made up of optical fibers. Here, the optical fibers of a protective f ~ \ sheath may be surrounded.
Glas ist der wichtigste Bestandteil der Lichtleitfaser. Dieses ist als nahezu idealer Isolator in vorteilhafterweise störstrahlungssicher vor elektromagnetischen Schwingungen der Störfelder von Starkstromnetzen und daher selbst bei der Übertragung stärkster elektrischer Ströme völlig störungsfrei. Die metallische Abschirmung und damit eine Gewichts- und Querschnittserhöhung des Starkstromkabels entfällt. Die Lichtleitfasern lassen sich bequem in den Zwickeln auch unterschiedlich gestalteter Phasen-Glass is the most important part of the optical fiber. As an almost ideal insulator, this is advantageously safe from interference radiation against electromagnetic oscillations of the interference fields of power networks and therefore strongest even during transmission electrical currents completely free of interference. The metallic shield and thus an increase in weight and cross-section of the power cable is omitted. The optical fibers can be conveniently placed in the interstices, even with differently designed phase

leiter unterbringen. Lichtleitfasern als Übertragungssystem für die Fernwirktechnik In Starkstromkabeln sind daher den Steuerleitungen aus Kupferdraht weit überlegen. Die Lichtleitfasern sind vorteilhafterweise von einer Schutzhülle umgeben, welche insbesondere bei der Herstellung des Kabels die Lichtleitfasern gegen Verletzung schützen.accommodate head. Optical fibers as a transmission system for telecontrol technology In power cables are therefore far superior to control lines made of copper wire. The optical fibers are advantageously surrounded by a protective sheath, which protect the optical fibers against damage, especially during the manufacture of the cable.
