In the prior art, the corroded copper braids are disposed of by discarding and replacing them. Since copper braids are easy to corrode, simply discarding and replacing them will cause waste of raw materials and increase costs. Therefore, it is urgent to carry out anti-corrosion protection of copper braided grounding wires.

Embodiment
[0020] Select a substation grounding copper braid and process it according to the following process:
[0021] Step (1) pickling: Pickling the substation grounding copper braids with a hydrochloric acid solution containing a copper corrosion inhibitor, the mass fraction of the hydrochloric acid is 3-5%, and the mass fraction of the copper corrosion inhibitor is 0.05-0.08 %, the time of the pickling is 20-30min;
[0022] Step (2) Washing: Use pure water to clean the grounding copper braids of the substation, and clean the residual hydrochloric acid; detect the pH value of the cleaning waste liquid, and when the pH value is greater than 6, the cleaning is over;
[0023] Step (3) Drying: within 30 minutes after washing, transfer the substation grounding copper braids to a drying box for drying. The drying temperature is 95±5°C and the drying time is 1 hour;
[0024] Step (4) Spraying: Spray transparent antistatic coating after cooling the dried substation grounding copper braids ...

Abstract
The invention relates to an anticorrosion treatment process for substation grounding copper braids, which comprises the steps of pickling, drying, spraying and drying the substation grounding copper braids. The invention has the advantages of simple and practical technology, convenient implementation, safety and reliability without affecting power supply, convenient construction at high places, and good anti-corrosion effect. A transparent protective layer can be formed on the surface of the treated material, which is resistant to bending, tortuousness, and good flexibility. It can effectively and continuously release static charges and avoid the accumulation of charges. The treated coating has excellent adhesion and impact resistance. This process can greatly improve the anti-corrosion performance of substation grounding copper braids, effectively avoid accidents caused by corrosion and fracture of grounding wires under harsh environmental conditions, improve the safety of power grid production, and can be extended to infrastructure grounding wires such as electric power, telecommunications, and networks in corrosion protection.
Description
technical field [0001] The invention relates to an anticorrosion treatment process for substation grounding copper braids. Background technique [0002] Power transmission and transformation equipment knife switch grounding copper braid is the most commonly used facility in substations. Because copper has good electrical conductivity, it is generally made of copper. At the same time, in order to facilitate the movement, the copper braided grounding wire is generally made of multiple copper wires braided with each other, which has good electrical conductivity and good flexibility, so it is widely used. [0003] The development of industry has caused more and more serious atmospheric pollution, and the corrosion of the atmospheric environment has also become more and more serious. As a copper braid ground wire exposed to the atmosphere, it cannot be avoided. Since copper braids are braided by many fine copper wires, their specific surface exposed to the atmosphere is relativ...
