Short-circuit point detecting and locating device for pipeline facility of railway track, has transponders activated or deactivated in short-circuit region by short circuit current, which exceeds preset threshold value

摘要

The device has a live conductor such as overhead wire (1), and a set of passive transponders (4.1-4.7) such as radio frequency identification (RFID) transponders, attached to a pipeline facility. The transponders are activated or deactivated in a region of short-circuit by a short circuit current, which exceeds a predetermined threshold value, by a passively operating electrical component for activation and/or deactivation of a transponder function.
