Abstract

The invention relates to the technical field of electric transmission lines, and discloses an electric transmission line grounding down lead suitable for rapid on-site anticorrosion treatment. According to the present invention, a protection material and an outer sheath are sequentially arranged on the surface of the electric transmission line grounding down lead, wherein the protection material comprises, by mass, 70-80 parts of ceramic micro-powder, 20-30 parts of zinc powder, 10-20 parts of shell micro-powder, 20-30 parts of 3,4-epoxycyclohexylformic acid-3',4'-epoxycyclohexanecarboxylate,6-10 parts of bis[2-(methacryloxy)ethoxy]dimethylsilane, 3-5 parts of triarylsulfonium hexafluoroantimonate salt, 6-10 parts of hyper-branched polyether polyol, 4-6 parts of polyethylene glycol, 1-3 parts of p-phenylenediamine, 1-3 parts of a defoamer, 1-3 parts of a dispersant, and 30-50 parts of ethanol; and the electric transmission line grounding down lead can effectively reduce the corrosionrate of the grounding down lead and greatly prolong the service life, can perform on-site anticorrosion treatment, and is fast and efficient.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a grounding downconductor of a power transmission line suitable for rapid on-site anti-corrosion treatment. Background technique [0002] The tower grounding device is an important part of the transmission line. It is the general name of the grounding body and the grounding downconductor. Its function is to ensure that the lightning current can reliably leak into the ground, protect the insulation of the line equipment, reduce the number of lightning trips on the line, and improve the reliability of power supply. With the development of the economy, the requirements for the reliability of power supply of transmission lines are getting higher and higher. At the same time, with the development of the power grid, the absolute value of tripping caused by lightning strikes on transmission lines is also increasing. The applicant made a statistics on the lightning strik...
