Electric spraying method of anti-pollution flashover paint for 500 kV transformer equipment

Abstract

The invention relates to the field of electricity, in particular to an electric spraying method of anti-pollution flashover paint for 500 kV transformer equipment. The method comprises a sweeping step and a painting step. The other end of an insulating rope is wound on a reel arranged at the lower end of a fixed supporting main rod, a sweeping insulating rod can be adjusted to ascend and descend through the winding of the reel, and an insulating brush is arranged at the end of the sweeping insulting rod; an atomization pressure working machine is powered on for conducting spraying. The electric operation method is completely different from a traditional operation method. The atomized paint or paint is conveyed into a conveying pipe of high insulation level through the pressure working machine under high pressure, the paint is conveyed to a spray nozzle at the upper end of an operation rod through the conveying pipe, the paint is sprayed to a porcelain bottle through the spray nozzle, the conveying pipe is filled with the atomized paint or paint, and the paint is of high insulation level, so that no air exists in the conveying pipe. Therefore, the absolute safety of the conveying pipe and materials inside the conveying pipe in the electric operation is guaranteed, and the personal safety is guaranteed absolutely.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method for electrified spraying of anti-fouling flashover coatings for 500kV substation equipment. Background technique [0002] In the power system, due to the wide range of anti-pollution flashover accidents in the power grid and the long power outage time, it seriously threatens the safe operation of power equipment and causes huge economic losses to the national economy; An important issue in the development of the industry, how to effectively solve the pollution flashover problem of the power grid has always been an important task to ensure the safe production of the power grid. [0003] In the 1980s, my country introduced a kind of RTV anti-fouling flashover coating from abroad, which has been widely promoted and applied in China. A large number of operating practices have proved that it is a good idea to apply a layer of RTV anti-fouling flashover coating on the external...

Problems solved by technology

[0002] In the power system, due to the wide range of power grid anti-pollution flashover accidents and long power outages, it seriously threatens the safe operation of power equipment and has caused huge damage to the national economy. Economic loss; therefore, the problem of anti-pollution flashover of the power grid has always been an important issue that plagues the development of the power industry. How to effectively solve the problem of pollution flashover of the power grid has always been an important task to ensure the safe production of the power grid

[0007]2. Power outage construction. Due to the limited power outage time and the uncertainty of climate conditions, practice has proved that the construction quality of RTV coatings is difficult to guarantee

[0008]3. The 500kV substation is a central substation. Once the power is cut off, it will affect the whole body, which will inevitably cause huge economic losses
