Abstract

The invention discloses a corrosion test method for a high voltage charged ERTV anti-pollution flashover coating, which belongs to the technical field of atmospheric corrosion simulation of anti-corrosion coatings. The method comprises the steps that a counter-force test bench in an L-shaped structure is manufactured; a reaction box is arranged on the inner side of the counter-force test bench; atension insulator coated with the high voltage charged ERTV anti-pollution flashover coating is placed in the reaction box; one end sequentially runs through the reaction box and the short side wall of the counter-force test bench through a first cable, and is fixed on the short side wall through a first tension device; the other end is connected with a high voltage power transmission system through a main power transmission line running through the reaction box; a branch power transmission line which runs through the reaction box and is connected with the high voltage power transmission system is arranged on the main power transmission line; and the reaction box is used to simulate the corrosion behavior of the high voltage charged ERTV anti-pollution flashover coating under natural environment climate conditions. The method provided by the invention is used to simulate the corrosion of atmospheric pollution, can be used for studying the corrosion behavior of the anti-corrosion coating under natural environment climate conditions such as high altitude, low temperature, dense fog, acid rain and damp heat, and can evaluate the anti-corrosion coating.

Description

technical field [0001] The invention belongs to the technical field of atmospheric corrosion simulation of anti-corrosion coatings, and in particular relates to a corrosion test method of high-voltage charged ERTV anti-pollution flashover coatings. Background technique [0002] The insulator on the transmission line has been exposed to the air for a long time. When there is a lot of dust between the sheds on the outer surface of the insulator, it is easy to cause pollution flashover. Pollution flashover refers to the dirt attached to the insulating surface of electrical equipment under humid conditions. The dissolved substance gradually dissolves in water, forming a conductive film on the insulating surface, which greatly reduces the insulation level of the insulator, and a strong discharge phenomenon occurs under the action of an electric field. There are many anti-pollution flashover measures. The traditional method is power failure cleaning in spring and autumn, and the u...
