Abstract
The invention discloses active field fully-magnetic shielding mouse-cage-shaped dry-type semi-iron-core reactor which comprises coils, a plurality of insulation stays, insulation pressing plates, a plurality of insulation cushion blocks, a plurality of air gap cushion plates, an iron core column and a mouse-cage-shaped fully-magnetic shielding shell. The air gap cushion plates are installed on the iron core column, the iron core column is wrapped tightly by belt type glass fiber insulation materials, and the coils are wound around the iron core column. The insulation stays are evenly placed between the coils and the iron core column at intervals, and the two insulation pressing plates are arranged at the two ends of the iron core column. The insulation cushion blocks are evenly placed between the two ends of the iron core column and the insulation pressing plates respectively at intervals. The axial direction of the iron core column is set to the vertical direction. 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 dry-type semi-iron-core 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.
