Description

1. Technical field [0001] The invention belongs to the field of power systems, and in particular relates to a device for testing the fouling characteristics of insulators in an artificially simulated haze environment and an operating method thereof. 2. Background technology [0002] In recent years, large-scale smog has frequently occurred in the central and eastern parts of my country, covering an area of ​​over 1.4 million km2, and nearly half of the 74 key PM2.5 monitoring cities have suffered serious pollution. Smog not only affects human health, but also poses a great safety hazard to power transmission and transformation equipment. It is mainly the increase of insulator surface pollution caused by haze weather and the wet deposition caused by haze and its influence on the pollution flashover voltage of insulators. In haze weather, when the relative humidity of the air reaches 80%-90%, a water film will be formed on the surface of the insulator, and the soluble salts a...

Problems solved by technology

However, the disadvantages of the research through the natural pollution of insulator strings are the long period and the large dispersion of field data obtained due to factors such as climate and sampling time.
