Description

Anordnung zur Beseitigung des Phasenfehlers bei Kabelschutzvorrichtungen mit im Leiterseil liegenden Nebenleitern Bei Kabelschutzvorrichtungen mit im Leiterseil. untergebrachten Nebenleitern, die auf dem Vergleich des Hauptleiterstremes und des Nebenleiterstromes beruhen, ergeben sich Schwierigkeiten infolge der Phasenverschiebung zwischen den Nebenleiterströmien und den Hauptleiterström-en. Bekanntlich ist der Strom in einem zentralen Nebenleiter nacheilend gegenüber dem Gesamtstrom, in einem am äußeren Umfang gelegenen Nebenleiter dagegen voreilend. Man hat schon vorgeschlagen, die Phasenverschiebung dadurch aus der Welt zu schaffen, daß man den Neben; leiter in das Innere des Kabels, und zwar an die Stelle verlegt, an der die Stromphase gleich der des Gesamtstromes ist. Dies ergibt gewisse Schwierigkeiten bei der Herstellung des Kabels, da die Isolation eines im Innern befindlichen Leiters während der Verseilung mehr gefährdet ist als diejenige eines zentral liegenden oddr eines am äußeren Umfang befindlichen Leiters.Arrangement for eliminating the phase error in cable protection devices with secondary conductors located in the conductor cable. With cable protection devices also in the conductor cable. accommodated secondary conductors based on the comparison of the main conductor stems and the Sub-conductor current based, there are difficulties as a result of the phase shift between the secondary conductor currents and the main conductor currents. It is well known that Current in a central secondary conductor lags behind the total current in one on the other hand, secondary conductors located on the outer circumference are leading. It has already been suggested to eliminate the phase shift by eliminating the minor; ladder in the interior of the cable, laid at the point where the current phase is equal to that of the total current. This gives rise to certain difficulties in manufacture of the cable, as the insulation of a conductor located inside during stranding is more endangered than that of a centrally located oddr one on the outer periphery located conductor.

Gemäß der Erfindung werden nun ein zentral liegender und daher leicht von dem übrigen Kabel zu isolierender Leiter und ein am äußeren Umfang gelegener, ebenfalls verhältnismäßig leicht zu isolierender Leiter parallel geschaltet, und zwar werden die Querschnitte dieser beiden Leiter, die aus mehreren Teilleitern bestehen können, so gewählt, daß die Phase des aus den Teilströmen resultierenden Nebenleiterstromes gleich der Phase des Gesamtstromes im Leiterseil bzw. der des Hauptl.eiterstromes ist, je nachdem der mit dem Gesamtstrom (gleich der Summe von Haupt- und Nebenleiterstrom, ) oder mit dem Hauptleiterstrom verglichen werden soll.According to the invention, a centrally located and therefore lightweight from the rest of the cable to be insulated conductor and one located on the outer circumference, also relatively easy-to-insulate conductors connected in parallel, and Although the cross-sections of these two conductors are made up of several sub-conductors may exist, chosen so that the phase of the resulting from the substreams Secondary conductor current equal to the phase of the total current in the conductor cable or that of the The main line current is, depending on the one with the total current (equal to the sum of Main and secondary conductor current,) or to be compared with the main conductor current.
