The invention discloses an 
electrical equipment flashover resistant cleaning device for 
field working. The 
electrical equipment flashover resistant cleaning device for 
field working comprises a cleaning head which is driven by a power device through a transmission hosepipe; and the cleaning head comprises a rotary 
brush which is vertically installed, one side of the rotary 
brush is covered with a protective cover with the cross section being a C shape, a 
handle is fixedly installed on the outer side of the protective cover, an upper rod extending horizontally is fixedly installed at the upper end of the inner side of the protective cover, the end of the upper rod is rotatably matched with the upper end of the rotary 
brush through an upper connection device, a lower rod capable of swinging up and down is hinged to the lower end of the inner side of the protective cover through a horizontal shaft, and the lower rod is rotatably matched with the lower end of the rotary brush through a lower connection device. The 
electrical equipment flashover resistant cleaning device for 
field working has the advantages that the structure is reasonable, the cleaning task can be quickly completed according to the shape of to-be-cleaned equipment, two 
modes of close distance cleaning and long distance cleaning can be switched over freely and quickly without changing the position where an operator is located, the cleaning angle can be adjusted freely, stubborn 
stain can be cleaned, no dead corner exists in cleaning, time and labor are saved, protectiveness on a cleaning staff is good, the cleaning staff do not breath dust and is not contaminated by dust, and the problem that 
dirt enters eyes does not exist; and the cleaned dust and 
dirt do not fall down to the lower equipment, the electrical equipment flashover resistant cleaning device is not limited by the cleaning height, one person can complete the cleaning task independently, and the cleaning effect is good.
