Um in Freileitungsnetzen, besonders Hochspannungsnetzen, bei Drahtbruch in einer Leitung ein sofortiges Abschalten des betreffenden Leitungsstranges zu bewirken, werden gemäß der Erfindung die Sammelschienen der Zentrale über eine unabhängige Stromquelle/ z. B. Gleichstrom (zweckmäßig unter Zwischenschaltung von Drosselspulen) oder Wechselstrom anderer Frequenz als der Netzfrequenz,In order to use overhead line networks, especially high-voltage networks, in the event of a wire break in a line, the relevant line is switched off immediately To effect line harness, the busbars are according to the invention Central via an independent power source / z. B. direct current (expediently with interposition of reactors) or alternating current with a frequency other than the mains frequency,
ίο an Erde gelegt und in jede der abgehenden Freileitungen, also bei Drehstrom in jede Phase, Relais eingeschaltet, die bei Durchgang des betreffenden Fremdstromes ansprechen und einen Kontakt für den Ausschaltmechanismus des zugehörigen ölschalters schließen, so daß eine Abschaltung des betreffenden Leitungsstranges erfolgt. ίο placed on earth and in each of the outgoing Overhead lines, i.e. with three-phase current in each phase, relays switched on, those with passage of the relevant external current respond and a contact for the switch-off mechanism of the associated oil switch close so that the relevant wiring harness is switched off.

ao Gleichstromspannung als unabhängige Stromquelle ist aus der Zeichnung näher zu ersehen. Es bezeichnen a, b und c die drei Sammelschienen, die z. B. über einen als Drosselspule dienenden künstlichen Nullpunkt d und eine Gleichstromspannung e an Erde gelegt sind, f ist ein Schalter, auf dessen Auslösemechanismus g die drei Relais h, i, k einwirken können. Die Relais sind so einge- · richtet, daß sie nur auf Gleichstrom ansprechen. ao DC voltage as an independent power source can be seen in more detail in the drawing. It denotes a, b and c the three busbars that z. B. via an artificial zero point d serving as a choke coil and a direct current voltage e are connected to earth, f is a switch on whose trigger mechanism g the three relays h, i, k can act. The relays are set up so that they only respond to direct current.
Tritt in einer der Leitungen, z. B. Leitung I, durch Drahtbruch Erdschluß ein, so bildet sich ein Gleichstromkreis: Erde, Gleichstromspannung β, Drosselspule d, Sammelschiene a, Schalter f, Relais h über Leitung I zur Erde. Das Relais h spricht an und gibt für den Auslösemechanismus von f Kontakt, so daß letzterer Schalter die zugehörige Freileitung abschaltet.Occurs in one of the lines, e.g. B. Line I, due to a broken wire earth fault, a direct current circuit is formed: earth, direct current voltage β, choke coil d, busbar a, switch f, relay h via line I to earth. The relay h responds and is for the trigger mechanism of f contact, so that the latter switch disconnects the associated overhead line.
