Room temperature vulcanized silicone rubber composite nano-material anti-pollution flashover coating is a coating material applied to the surface of insulators of high-voltage power equipment, which can well improve the special performance of water immersion resistance. The coating is different from other polymerized new monomer coatings, but a coating formed by a polymer interpenetrating network structure. It utilizes the excellent antistatic adsorption and hydrophobicity of fluoride materials and the excellent hydrophobicity of silicone materials to significantly reduce the adsorption effect of water droplets, dust and charged particles on the surface of the coating, and has good self-cleaning and weather resistance, effectively achieving the purpose of long-term anti-pollution flashover and anti-icing in the power system.
The long-term hydrophobic anti-pollution flashover coating is used on the porcelain insulation of the power system to improve its anti-fouling flashover and anti-icing performance. The nano-carbon anti-corrosion conductive paint with thermal stability is characterized in that it is mainly composed of nano-carbon, organosilicon high-temperature resistant resin and organic solvent; the organic solvent is xylene. It has the characteristics of good corrosion resistance, electrical conductivity and thermal stability.
The new nano-composite anti-pollution flashover coating adjusts the viscosity of the anti-pollution flashover coating and injects it into the coating tank of the spraying machine; cleans the surface of the insulator, clamps the two ends of the insulator laterally with a pair of clamps that can rotate in the same direction, and slowly rotates the clamps to make The insulator rotates accordingly; turn on the sprayer and spray from above the anti-fouling flash of the insulator; turn off the sprayer and keep the fixture rotating; turn on the sprayer and spray from above the insulator; turn off the sprayer and keep the fixture rotating and then stop it, and keep the insulator in a clean environment for 12 hours.
Through the coating method of the insulator anti-pollution flashover coating, a product that meets requirements and has stable quality can be obtained, and the personal injury is small. RTV anti-pollution flashover high-voltage ceramic and glass insulators are especially suitable for power transmission and transformation lines in areas with severe environmental pollution or remote areas that are not easy to maintain. They can greatly reduce the maintenance and operation costs of power transmission and transformation circuits, and reduce the occurrence of industrial accidents. The anti-pollution flashover coating is hydrophobic, and it is characterized in that fluorescent substances are added to the anti-pollution flashover coating material. When the anti-pollution flashover coating fails, deteriorates, or the porcelain bottle is damaged or the pollution is particularly serious, the anti-pollution flashover coating will be discharged to produce ultraviolet rays and fluorescence. The substance emits visible light under the irradiation of ultraviolet rays, so that the power equipment with problems can be found with the naked eye at night, and dealt with in time, which can prevent the occurrence of power system blackout accidents.
