ABSTRACT:
An amorphous transformer prevents deformation or deflection caused by the repulsion force between an outer coil and an inner coil and prevents formation of a one-turn-current through a reinforcement member and a coil frame. The amorphous transformer includes amorphous cores, an outer coil and an inner coil, a coil frame and a reinforcement member. The reinforcement member prevents the amorphous core from being deformed inward by the electromagnetic force of the coil, and the frame member and the reinforcement member prevents formation of an electrical closed-loop. Accordingly, the amorphous transformer core is protected from being damaged.
