Dry ice cleaning vehicle of electrical equipment external insulation

Abstract

The invention relates to a dry ice cleaning vehicle of electrical equipment external insulation, belonging to the cleaning equipment of the electrical equipment external insulation. A lifter (7) is fixed on a vehicle body (8); the top end of the lifter (7) is provided with a lift platform (3) on which an insulation telescopic arm (2) is arranged; the telescopic end of the insulation telescopic arm (2) is connected with an automatic dry ice particle track sprinkler head assembly (1); and a dry ice conveying insulation duct (4-1) on a dry ice conveying device (4) is communicated with a sprinkler head (1-8) on the automatic dry ice particle track sprinkler head assembly (1). The invention has the advantages of compact structure, larger inclusive area for cleaned objects, almost no cleaning dead corner, large one-step cleaning surface, high cleaning quality, convenient operation and high dirt removal efficiency, thereby being especially suitable for the cleaning work of vertically arranged cylindrical insulating equipment, such as insulators or sleeve pipes. The invention can be used as high-efficiency cleaning equipment for safe electric power production and electric power supply guarantee and has favorable social and economic benefits.

Description

technical field [0001] The invention relates to a cleaning device for external insulation of electrical equipment, in particular to a dry ice cleaning vehicle for external insulation of electrical equipment. 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 cases, it will affect the safe operation of electrical equipment a...
