The utility model provides a transformer silica gel drying device which comprises a cylinder body with a driving motor, a water outlet hole is formed in the cylinder body, a coil used for generating eddy current is arranged on the inner wall of the cylinder body, the coil is connected with a controller through a driving control circuit, and the driving control circuit is connected with the drivingmotor. The cylinder body comprises an upper cylinder body, a middle cylinder body and a lower cylinder body. The upper cylinder body is in a semi-spherical arc shape, the middle cylinder body is cylindrical, the lower cylinder body is in a semi-spherical shape, the joint of the upper cylinder body and the middle cylinder body is a plane, and the joint of the lower cylinder body and the middle cylinder body is a plane. According to the scheme, the problems faced by an existing transformer silica gel drying method can be effectively solved, and cyclic utilization of silica gel is reliably achieved in time. And in addition, timely regulation and control are achieved in the drying process, and the situation of collision or uneven drying is avoided.
