The invention discloses a lifting device for maintenance of a mutual inductor. The lifting device comprises a fixed seat and an expansion device, wherein the fixed seat is matched with the base of the mutual inductor, and can be fixed on the base of the mutual inductor; the lower end of the expansion device is fixed on the fixed seat; and a lifting arm is arranged at the upper end of the expansion device, and is provided with a lifting hook. When the lifting device is used for maintaining, the fixed seat is fixed on the base of the mutual inductor, the lifting arm is moved to the position of the shell of the mutual inductor, the shell of the mutual inductor is hooked by utilizing the lifting hook and is lifted by virtue of the expansion device, so that maintenance can be directly carried out. Compared with a crane, the whole lifting device has the advantages of small size, convenience in assembly, low operation risk and the like, and can be used for effectively reducing the power-failure range in actual application and improving the safety reliability of the power grid.
