Title:
DEVICE AND METHOD FOR DETECTING HIGH-VOLTAGE POWER DISTRIBUTION LINE PATH HAVING IMPROVED STABILITY
Document Type and Number:
WIPO Patent Application WO/2019/190170
Kind Code:
A1
Abstract:
In order to resolve a problem, a device for detecting a high-voltage power distribution line path having improved stability is disclosed in one embodiment of the present disclosure. The device for detecting a high-voltage power distribution line path can comprise: a detecting-current generator for generating a current pulse signal in inverse proportion to a winding ratio by being connected to a secondary winding of a distribution transformer such that a magnetic signal near a high-voltage power distribution line can be detected, thereby identifying a buried path to a final power source and a connection configuration of a power distribution system by being connected to a primary winding of a distribution transformer for converting a high voltage for distribution into a low voltage in proportion to a winding combination ratio so as to track the high-voltage power distribution line, which supplies a voltage and a current; a buried path detector, which detects the magnetic signal generated around the high-voltage power distribution line when the current pulse signal flows along the high-voltage power distribution line, so as to track a buried path and a connection configuration of the high-voltage power distribution line; and a reverse current limiter for suppressing the generation of a reverse magnetic field generated by an outer conductor of the high-voltage power distribution line, in order to improve the reception performance of the buried path detector.
