An artificial fouling characteristics test system and its operating method

Abstract

The invention belongs to the field of power systems and discloses an artificial pollution accumulation characteristic testing system and an operating method thereof. The system comprises a wind source power section, a test section and an air duct diffusion and dust removal section which are communicated in sequence; the wind source power section is used for providing natural wind for the test section; the test section is used for simulating the pollution accumulation condition of an insulator of a power grid; the air duct diffusion and dust removal section is used for collecting dust and providing an air duct outlet; and the wind source powder section is provided with a base for supporting the testing system. The testing system is internally provided with a draught fan, a dust spreading device, the insulator and the like, so that the artificial simulation for the natural pollution accumulation conditions of the insulator in typical environments such as wind, rain, fog and the like and different pollution degrees in a laboratory is realized; compared with the traditional method for researching the natural pollution accumulation characteristic through circuit sampling, the operating method is time-saving and labor-saving, safe and reliable as well as wide in research range; and a research result has important significance for the operation maintenance as well as the design and selection of the insulator of a power transmission line.

Description

technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to an artificial fouling characteristic test system and an operating method thereof. Background technique [0002] Dirt will be deposited on the surface of insulators exposed to the air for a long time. In snow, fog, drizzle and other humid weather, the soluble salts in the dirt will dissolve in water and become conductive, reducing the dielectric strength of the insulator, and even causing Pollution flashover leads to interruption of power supply, which seriously affects industrial production and people's daily life. Under certain environmental conditions, the shape of the insulator has a major impact on the deposition of pollutants on the surface of the insulator. Therefore, the atmospheric environment in which the insulator operates is simulated in the laboratory, and the insulator with less pollution and high pollution flashover voltage under this environment is...

Problems solved by technology

[0007] When taking insulators, due to the long time of natural pollution and the cumbersome steps of sampling outdoor lines, the staff need to climb up the pole tower, which poses a safety hazard, and the sampling is completed and brought back to the laboratory for measurement. The process is long, and there may be samples during the process. In the case of scattered and lost, the measurement reliability is not high
