Dedusting, cooling and dehumidifying device for electrical equipment

The utility model discloses a dedusting, cooling and dehumidifying device for electrical equipment. In the prior art, when electrical equipment is subjected to dust removal, suspended dust in air is driven through air circulation, dust adhering to the surfaces of an electrical mounting frame and the electrical equipment is difficult to clean, and the dust removal effect is poor. A box body (4) is fixedly connected to the upper portion of the base, a movable door (2) is installed on the side surface of the box body, an electrical equipment frame mechanism (7) is installed in the box body, an air inlet in the bottom of the box body is connected with an air inlet mechanism (5) with a filtering function, and an air outlet in the top of the box body is connected with a negative pressure pump mechanism (1). The lower portion of the shifting mechanism (8) is arranged above the electrical equipment frame mechanism, the air outlet direction of the negative pressure pump mechanism faces the shifting mechanism, the elec
