The invention discloses a snow removal device for electrical equipment, and belongs to the field of electrical equipment maintenance devices. The snow removal device comprises a supporting lifting mechanism, a limiting protection mechanism, a moving mechanism and an ice and snow removal mechanism, wherein the limiting protection mechanism comprises a limiting rod and a rotary cutting disc; the rotary cutting disc can be driven to rotate and horizontally move; the ice and snow removal mechanism mainly comprises a spacing roller, a dislocation roller and a scraper roller; an ice shaving knives are distributed on the spacing roller and the dislocation roller; an ice scraping knife is arranged on the scraper roller; the distance between the bottom of each roller and the rotary cutting disc isequal to that between the bottom of a limiting sleeve and the top of a limiting rod; the rollers and the limiting sleeve move synchronously; collecting holes penetrating through corresponding knife bodies and communicated with corresponding rollers are formed in the ice shaving knives and the ice scraping knife; and a suction ventilator communicated with a corresponding roller is mounted at one end of each roller. The snow removal device is accurate in mechanism travel control, can prevent the surface layer of the electrical equipment from being damaged, is high in ice and snow removal efficiency and good in effect, and can further prevent snow water from permeating the electrical equipment after ice and water are molten.
