The utility model is provided with a dust collection cabinet and a dust cleaning cabinet at the upper end of the base plate, respectively, and an exhaust fan and a blowing fan are arranged inside the dust collection cabinet and the dust cleaning cabinet, respectively. The blowing fan can conveniently clean the dust outside and inside the high-voltage electric power equipment. When the blowing fan cleans the inside of the high-voltage electric power equipment, a large amount of dust is stuck inside the high-voltage electric power equipment and cannot come out. Because of the exhaust fan, the dust floating inside the high-voltage electric power equipment can be easily sucked into the dust collection cabinet, which is conducive to more practical use of the live insulation cleaning device for high-voltage electric power equipment, is more practical, and is suitable for wide promotion and use.
