Emergency protection device for high-voltage power distribution cabinet

The invention relates to the technical field of electrical equipment, in particular to an emergency protection device for a high-voltage power distribution cabinet, which comprises a fixed base, the fixed base is fixedly mounted at the top of the inner wall of the high-voltage power distribution cabinet, two symmetrically arranged guide rails are fixedly mounted at the bottom of the fixed base, and a storage groove of a U-shaped structure is formed in the bottom of the fixed base. And an isolation belt made of a flexible material is fixedly mounted in the storage groove. According to the high-voltage power distribution cabinet, the fixed base is designed, the isolation belt can be timely unfolded through the counterweight strips on the fixed base when a fire occurs in the high-voltage power distribution cabinet, and the unfolded isolation belt can play a role in isolating the fire generated in the high-voltage power distribution cabinet; and meanwhile, a fire source in the high-voltage power distribution cabi
