The three iron core columns are coaxial and are arranged in parallel. The insulated bushings are arranged on the circumferential outer surfaces of the corresponding iron core columns. The coils are arranged on the circumferential outer surfaces of the corresponding insulated bushings. The coils are formed by connection of a plurality of layers of overlaid coil windings. An Insulating layer is arranged between adjacent coil windings. A gap is arranged between adjacent coils. The axial direction of each iron core column is arranged to be an up-down direction. The upper insulated board and the lower insulated board are respectively arranged at the upper ends and the lower ends of iron core columns. The mouse cage shape full-magnetic shielding shell is formed by connection of horizontal magnetic shielding boards and vertical shielding walls. The active field full-magnetic shielding mouse cage shape iron core current-limiting reactor is capable of shielding electromagnetic waves inside the mouse cage shape full-magnetic shielding shell, and damage to living organisms, air, instruments and devices and the environment outside the shielding shell is not generated.
