technical field

In converter stations and substations, a large amount of dirt will adhere to the surface of composite insulators exposed to the outdoors for a long time. Dust in the air, industrial waste gas, industrial soot, oil particles and other particles or bird droppings will accumulate on the outer surface of the insulator. The formation of a contamination layer, in the case of damp, will lead to a decrease in the insulating ability of the surface of the insulator and an increase of the surface leakage current, thus causing a pollution flashover accident under normal voltage operation. The pollution flashover accident has a great impact on the power system, and even causes the paralysis of the entire power grid. Therefore, the composite insulator must be cleaned or replaced in time.
