Safe explosion-proof electrical cabinet with insulation protection function

The invention relates to the technical field of electrical cabinets, in particular to a safe explosion-proof electrical cabinet with an insulation protection function, which comprises an electrical cabinet, a drainage box and a heat dissipation plate, a storage box is fixedly mounted at the top of the electrical cabinet, a rainproof box is slidably connected to the top of the storage box, and heat dissipation holes are formed in the outer wall of the electrical cabinet. A sealing plate is slidably connected to the inner wall of the electrical cabinet, the sealing plate is made of an insulating material, and the side wall of the sealing plate is fixedly connected with one end of a connecting block; the electrical cabinet has the beneficial effects that the sealing plate of the electrical cabinet can automatically seal the heat dissipation holes when it rains, the phenomenon that rainwater intrudes into the electrical cabinet is avoided, damage to electrical elements caused by the rainwater is prevented, and wh
