Abstract

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 earthing pedestal 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 present invention relates to an external insulation decontamination technology for electrical equipment of a power system, in particular to a dry ice cleaning system that can insulate the external electrical equipment under live working conditions. Background technique [0002] Pollution flashover of electrical equipment means that the soluble matter of the dirt attached to the insulating surface of the electrical equipment gradually dissolves in water under humid conditions, forming a conductive film on the insulating surface, which greatly reduces the insulation level of the insulator. Under the action of an electric field A strong discharge phenomenon occurs. Although there are many existing anti-pollution measures, such as the use of anti-pollution insulators, climbing adjustments, increasing the number of insulators, etc., the insulation of electrical equipment in polluted areas can easily be broken down under severe weather, resulting in pollution...
