High tension line open circuit positioning device

Abstract

The invention discloses a high tension line open circuit positioning device, which consists of a carrier receiving unit, a data processing unit, a warning and prompting unit and calibrating units, wherein the carrier receiving unit, the data processing unit and the alarming and prompting unit are arranged in an electrical room or at a transformer substation; the calibrating units are arranged on an electric power circuit; each calibrating unit is coupled with one or more coupled circuits and transmits an identifier through an electric power line; a calibration code transmitted by each calibrating unit is unique; and the data processing unit processes the identifier transmitted by each calibrating unit. The high tension line open circuit positioning device discovers a disconnection fault intime through carrier communication, provides disconnection point positioning information, has the functions of dialling automatically and warning in voice, and creates a condition for discovering andprocessing a fault in time. The open circuit positioning device for the high tension line is convenient to arrange and use without changing the original circuit.

Description

technical field [0001] The invention relates to a device for online fault detection of a power supply line, which belongs to a power line disconnection alarm device. Background technique [0002] There are main problems of the product: it cannot work when there is a power outage; there is no positioning function for the location of the broken line, and for the occasions with long lines or complex terrain, the staff cannot send personnel to the scene to deal with them in time, especially if the line is artificially cut If the location cannot be quickly located, it is difficult to better protect the safety of the power supply line, especially when the high-voltage power line is in operation due to weather, environment, external force, insulation aging and other reasons, open-circuit faults often occur, and the location of the fault point can be accurately measured , To eliminate the hidden dangers of high-voltage lines and restore power supply as soon as possible is a crucial ...
