Abstract
The invention discloses an active field fully-magnetic shielding mouse-cage-shaped compensation reactor comprising coils, an iron core column, insulation stays, an upper insulation plate, a lower insulation plate and a mouse-cage-shaped fully-magnetic shielding shell. The iron core column is an integrally-formed II-type iron core column, the number of the coils is two, the coils are respectively wound around two side columns of the iron core column, the insulation stays are arranged between the coils and the side columns of the iron core column, the upper insulation plate and the lower insulation plate are arranged at two ends of the iron corn column respectively and connected through a central screw rod, the axial direction of the iron core column is to be the vertical direction, and the mouse-cage-shaped fully-magnetic shielding shell is formed by connecting magnetic shielding plates in the horizontal direction and magnetic shielding walls in the vertical direction. The active field fully-magnetic shielding mouse-cage-shaped compensation reactor shields electromagnetic waves into the mouse-cage-shaped fully-magnetic shielding shell, and protects biological organisms, air, instruments, equipment and environment outside the shielding shell from being damaged by the electromagnetic waves.
