Composite insulators contamination process has a complex dynamic characteristics

Composite insulators on the contamination process has a complex dynamic characteristics. Various atmospheric conditions. Wind, rain. Fog, snow and humidity that the contamination of the impact, and can influence a factor often different. Wind energy dust. The waste can blow insulators have aggravated the contamination effect. But after the wind speed reaches a certain speed , they can blow away the grime from the surface of the insulator having purification. And at various Winds pollution source within the surrounding area have a certain concentration of the waste material, favorable conditions for waste fallout is very slow diffusion windless situation. humidity of the insulating surface moist can accumulate more waste. On the other hand thousands of humidity can prevent or diminish the soil up. fog can hinder the waste spread. increasing concentrations of waste in the air. It can promote the same filthy drizzle was deposited on the insulator surface. But the larger rain. can wash away the dirt but also the role of purification, usually on the ground air layer temperature decreases with height. In this case the vertical movement of air. cold air drop. Hot air rises. So that the surface over the contamination degree is reduced. However, under certain meteorological conditions (such as extreme cold at night when the surface temperature), may be a so-called inversion layer, temperature increases with increasing height. Air near the surface seems to be Off in a limited space. near the surface of the waste can reach very high concentrations, will greatly promote the contamination. Under normal circumstances the inversion of short duration, but also the presence of a few days the situation could lead to a major accident. The above described. Meteorological intricacies of the contamination, and changes in weather is seasonal. To insulator stabilize the situation and make conclusions on the contamination should be monitored by several years.
