Protective device of current protector

The utility model relates to the technical field of current protector protection, in particular to a current protector protection device which comprises a base, a sleeve frame connected to the outer wall of the base, bolts connected to the two ends of a transverse symmetry axis on the two sides of the inner wall of the sleeve frame, a current protector base body fixedly connected to the center of the top of the base, and a protection shell connected to the top of the sleeve frame. The dust-proof ventilation net is arranged, so that air in the protective shell can circulate more smoothly, the motor and the fan shaft structure are arranged, when the motor drives the fan shaft to rotate, the air circulation speed in the protective shell can be increased, the fan shaft can be prevented from rotating, the fan shaft is prevented from rotating, and the service life of the fan shaft is prolonged. By arranging the heat dissipation cylinder and the top cover, heat generated by the current protector can be quickly disch
