The invention discloses a external-insulation dry-ice cleaning system for electrical equipment, which belongs to the technical field of the external-insulation dirt removal of electrical equipment of an electrical system. The external-insulation dry-ice cleaning system adopts the structure that a dry-ice particle spray nozzle (1), an insulating adjustable bracket (2), a dry-ice transmission insulating pipe (3), a dry-ice cleaning device (5), an air compressor (6) and an air dryer (7) are sequentially connected with each other front and back, wherein the dry-ice particle spray nozzle (1), the insulating adjustable bracket (2), an insulating bracket regulating lever pipe (4) and a bracket regulating power device (8) are sequentially connected with each other from front and back, a dry-ice making granulating machine (10) is connected with a liquid carbon dioxide storage tank (11), a dry-ice insulation can (12) is independent equipment, and an earthing base (9) is taken as a safe earthingpedestal of the external-insulation dry-ice cleaning system. The invention has high dirt removing efficiency, is suitable for the on-line cleaning of an insulating sleeve and an insulating mainstay or an erected transmission line insulator inside a transformer station, and is an effective measure for safely generating the electricity and ensuring the electricity supply.
Description
technical field [0001] The invention relates to the external insulation and decontamination technology of electrical equipment in a power system, in particular to a dry ice cleaning system capable of external insulation of electrical equipment under live working conditions. Background technique [0002] Pollution flashover of electrical equipment refers to the fact that the soluble substances of the dirt attached to the insulating surface of electrical equipment gradually dissolve in water under humid conditions, forming a conductive film on the insulating surface, which greatly reduces the insulation level of the insulator. A strong discharge phenomenon occurs. Although there are many existing anti-pollution measures, such as the use of anti-pollution insulators, anti-climbing, and increasing the number of insulators, etc., the insulation of electrical equipment in polluted areas is easily broken down in harsh weather, resulting in pollution flashover accidents , In severe...
