Anti-pollution flashover means that the pollutants attached to the insulating surface of electrical equipment are gradually dissolved in water under humid conditions, and a conductive film is formed on the insulating surface, which greatly reduces the insulation level of the insulator. Anti-pollution flashover coating is a very important coating. In severe weather conditions, anti-pollution flashover coatings are protective measures to ensure the safe operation of power systems and reduce the impact of moisture in the air on the power grid.
Anyone who does power engineering knows that pollution flashover is very serious. Once it occurs, it will not only cause failure of power lines, but also may cause large-scale power outages. Therefore, anti-pollution flashover coatings are generally used for insulation in power engineering to prevent pollution flashover. Here the anti-pollution flashover coating manufacturer, Ruisen, will introduce the precautions for painting.
The packaging drum should be sealed and tightly closed immediately after use to avoid prolonged contact of the paint with the air to prevent the paint from curing. Construction should be carried out in fine weather, and construction under bad weather such as rain and fog and heavy dust is prohibited to ensure construction quality. The surface of the porcelain insulator must be cleaned before the coating is applied to strictly prevent grease, dust and moisture from remaining on the surface of the porcelain insulator. When overcoating the coated insulator, the dirt and the peeling and warped coating on the original coating surface should be removed. For the original coating with good adhesion but failed, it is not necessary to remove it. It can be overcoated directly on it without affecting the quality of overcoating.
The anti-pollution flashover coating is developed using polymer synthesis technology and hydrophobic migration catalytic slow-release technology, combined with organosilicon fluorine materials and nanotechnology. At the same time, the filler, pigment and dispersion process are carefully selected, so that the addition ratio of filler and pigment is very small, so as to ensure that the coating product has a high concentration of silicone rubber and the mechanical strength is greatly improved.
By using high-pressure equipment to spray anti-pollution flashover coatings, good results have been achieved in controlling pollution flashover accidents. Due to the reasonable calculation of the leakage ratio, the discharge voltage of the insulator is increased, and the flashover accident of the insulator is significantly reduced. At the same time, it also reduces various maintenance costs and reduces the labor intensity of employees.
