Description

Transmission line state data acquisition device

Technical Field

The ultra-high voltage transmission line is affected by severe weather such as low temperature, rain and snow, freezing and strong wind in a large range, and phenomena such as icing, waving and vibration in a large area occur, wherein the waving, vibration and sag of a wire enable a plurality of lines to have flashover tripping, loosening of bolts of tower materials, collision damage of insulators, breakage of jumper wires, damage and breakage of hardware such as spacers and the like, damage of tower structures, tower falling and other accidents in different levels, and serious disasters are caused to a power grid. In order to prevent the accidents from causing further damage, a plurality of data acquisition devices are required to be arranged on the power transmission line to detect the line galloping state so as to take measures in time after the accidents occur.

Corona is one of the important causes of power loss in power systems. According to incomplete statistics, the electric energy lost by corona in China every year reaches 20.5 hundred million kW.h. The corona is generated because the uneven conductor generates a very uneven electric field, and when the voltage around the electrode with a small curvature radius around the uneven electric field rises to a certain value, the air is dissociated to generate discharge, so that the corona is formed. Corona occurs mostly where the radius of curvature of the conductor is small.
