Technical Field

Background
The insulator is a special insulating control part and is used for supporting and fixing the bus and the live conductor, so that the live conductor or the conductor has enough distance with the ground. After the insulator runs for a long time in a natural environment, pollutants are gradually deposited on the surface of the insulator due to the influence of environmental factors such as industrial emissions, natural dust and the like. When wet weather occurs, soluble substances in the dirt layer are dissolved in water to form a conductive water film, so that leakage current flows along the surface of the insulator. Due to the influence of factors such as the shape, the structural size and the like of the insulator, the current density of each part on the surface of the insulator is different, a dry area is formed at the part with higher current density, the distribution of the surface voltage of the insulator is more uneven due to the formation of the dry area, and the dry area bears higher voltage. When the field strength is sufficiently high, creeping discharges will occur across the dry zone, which intermittent discharge conditions may last for a considerable time, when the dirty and wet conditions are severe, local arcs will develop gradually, and when critical conditions are reached and exceeded, arcs will run through both poles, causing flashover. The occurrence of pollution flashover accidents caused by dirt accumulation seriously affects the safe operation of a power system, and meanwhile, a power transmission line is easy to be iced under the environments of rain, snow, low temperature and the like, so that the vertical load of the line is too heavy to cause the line to collapse, and therefore, the maintenance of the dryness and cleanliness of the surface of an insulator becomes an important way for preventing the occurrence of icing and pollution flashover accidents.
The surface of the existing partial anti-pollution flashover insulator is made of super-hydrophilic materials, a water film formed after the super-hydrophilic materials meet water can keep the cleanliness of the insulator to a certain degree, but the water film formed by the hydrophilic materials is easy to cause the insulator icing phenomenon under low-temperature rain and snow weather, the anti-icing insulator cannot ensure the cleanliness of the insulator, and the products have no way to solve the problems of pollution and icing at the same time.
