Description
technical field [0001] The invention relates to an insulator pollution correction method, in particular to a material-based insulator pollution correction method. Background technique [0002] With the rapid growth of urban and rural economy, my country's air pollution is becoming more and more serious. Overhead line insulators are susceptible to contamination by natural salt, industrial pollution, dust, bird droppings and other pollutants. Under heavy pollution and wet conditions, the surface of the insulator will become wet enough to form a continuous water film on the dirty layer, which will significantly increase the surface conductivity of the insulator, thereby destroying the electrical insulation performance of the insulator. In this case, the outdoor insulation is prone to pollution flashover. Insulator pollution flashover still threatens the stable operation of the power system. The accumulation of pollution on the surface of insulators is the premise of pollutio...
