Embodiment

[0025] Transmission towers (tower 1 to tower n) are distributed at intervals. The overhead ground wire (lightning protection line) of the transmission tower and the transmission line of the transmission tower are erected in parallel, and there is mutual inductance between them. The overhead ground wire and the tower ground form a loop, thus forming a loop current.

[0026] A power transmission tower grounding state sensing device, comprising an impulse current wave generation module, an acquisition module, an A / D conversion module, a data processing module, a data storage module, a judgment module and a mobile terminal, an impulse current wave generation module, an acquisition module, an A / D The D conversion module, the data processing module, the data storage module, the judging module and the mobile terminal are sequentially connected through wireless communication;

[0027] The impulse current wave generation module is used to output the impulse current wave and apply the i...

Abstract

The invention discloses a transmission tower grounding state sensing device. The device comprises an impact current wave generation module, an acquisition module, an A / D conversion module, a data processing module, a data storage module, a judgment module and a mobile terminal, and the impact current wave generation module, the acquisition module, the A / D conversion module, the data processing module, the data storage module, the judgment module and the mobile terminal are sequentially connected through wireless communication. According to the invention, the device achieves the online monitoring of the grounding grid conduction condition of the tower grounding grid under the conditions of no power failure and no excavation of the grounding grid, timely finds out the accident hidden troubles, timely locates a fault point, timely provides a scientific and reliable basis for the maintenance and transformation of the grounding grid, prevents the possible damages caused by the faults of thegrounding grid, and guarantees the safe and reliable operation of a power system.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a grounding state sensing device for power transmission poles and towers. Background technique [0002] The pole tower is a pole-shaped or tower-shaped structure that supports the overhead transmission line conductor and the overhead ground wire and keeps a certain distance between them and the ground. It is one of the basic equipment in the overhead power distribution line. [0003] The grounding of transmission line towers is crucial to the safe and stable operation of power systems. Lightning accidents due to poor grounding of towers account for a relatively high proportion of line accidents. The grounding grid of power transmission line towers is buried underground, and its corrosion status and specific corrosion locations are mostly determined through offline grounding resistance tests and grounding continuity tests. judge. This kind of discrimination meth...
