   PATENT CLAIM:
Signaling device for fault location in line systems, especially railway contact line systems, in which in one of the two conductors in predetermined sections each inductively coupled with these, exceeding a predetermined limit value of the line current responsive switching devices are arranged at the end of each section facing away from the feed point, of which if present a short circuit, all switching devices located between the feed point and the short circuit point respond, the switching device being formed by a protective gas switch which is known per se and is switched as a function of the magnetic field;

   which is covered by an insulator around which a loop of the conductor is wrapped, according to patent no. 31331
 EMI1.1
 Switching devices at the ends of the faulty subsection have two-sided or multilateral-fed lines that have opposite signs after the protective gas switch has responded, but have the same sign in all other subsections.

** WARNING ** End of DESC field may overlap beginning of CLMS **.

<Desc/Clms Page number 1> <Desc / Clms Page number 1> Das Patent Nr. 313369 betrifft Meldeeinrichtungen zur Fehlerortung in Leitungsanlagen, besonders Fahrleitungsanlagen, bei denen in einem der beiden Leiter in vorgegebenen Teilabschnitten jeweils mit diesen induktiv gekoppelte, bei Überschreiten eines vorgegebenen Grenzwertes des Leitungsstromes ansprechende Schalteinrichtungen an dem der Speisestelle abgewandten Ende jeden Abschnittes angeordnet sind, von denen bei Vorliegen eines Kurzschlusses alle zwischen Speisestelle und Kurzschlussstelle liegenden Schalteinrichtungen ansprechen, wobei nach Patent Nr. 313369 die Schalteinrichtung durch einen an sich bekannten Schutzgasschalter gebildet ist, der durch einen Isolator umhüllt ist und um den eine Schleife des Leiters gelegt ist. Patent No. 313369 relates to reporting devices for fault location in line systems, especially contact line systems, in which in one of the two conductors in predetermined sections, switching devices that are inductively coupled to them and respond when a predetermined limit value of the line current is exceeded are arranged at the end of each section facing away from the feed point , of which all switching devices located between the feed point and the short-circuit point respond in the event of a short circuit, whereby according to Patent No. 313369 the switching device is formed by a gas-shielded switch known per se, which is encased by an insulator and around which a loop of the conductor is placed. Es wurde nun erkannt, dass es ohne wesentlich erhöhten Aufwand möglich ist, diese Einrichtung auch zur Feststellung der Richtung des in der Leitungsanlage fliessenden elektrischen Stromes heranzuziehen, indem im Inneren des Hohlisolators zusätzlich eine Spirale in dem Bereich des Magnetfeldes der Leitung angeordnet ist, an der eine vom Leitungsstrom induzierte elektrische Grösse abgegriffen wird. It has now been recognized that it is possible without significantly increased effort to also use this device to determine the direction of the electric current flowing in the line system by additionally arranging a spiral in the area of the magnetic field of the line inside the hollow insulator an electrical quantity induced by the line current is tapped. Da die Leitungsrichtung in einem kurzschlussbehafteten Leitungssystem immer zum Fehlerort zeigt, sind die Vorzeichen dieser elektrischen Grösse zu gleichen Zeitpunkten, die durch das Ansprechen des Schutzgasschalters festgelegt sind, bei zwei- oder mehrseitig gespeisten Leitungen in den Schalteinrichtungen, die den fehlerbehafteten Teilabschnitt begrenzen, verschieden, in allen andern jeweils zwischen den Speisestellen und der Kurzschlussstelle liegenden Teilabschnitten jedoch gleich. Diese Anordnung zeigt also einen Fehlerort auch in zweiseitig gespeisten Leitungen und in vermaschten Netzen durch den Wechsel des an Meldeeinrichtungen angezeigten Vorzeichens der momentanen Stromrichtung an. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. Since the direction of the line in a line system with short circuits always points to the fault location, the signs of this electrical variable are different at the same points in time, which are determined by the response of the protective gas switch, in the case of lines fed on two or more sides in the switching devices that limit the faulty section, however, it is the same in all the other subsections lying between the feed points and the short-circuit point. This arrangement also shows a fault location in lines fed from both ends and in meshed networks by changing the sign of the current direction of current displayed on signaling devices. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
