Iron core magnetically-controlled reactor

The utility model belongs to the technical field of power grid electrical equipment and particularly relates to an iron core magnetically-controlled reactor which is convenient to operate and adjust. The iron core magnetically-controlled reactor comprises middle vertical main iron core pillars, a vertical front side pillar, a vertical rear side pillar, a transverse upper yoke and a transverse lower yoke. The iron core magnetically-controlled reactor is characterized in that the upper end and the lower end of the front side pillar are connected with the front end of the upper yoke and the front end of the lower yoke respectively, the upper end and the lower end of the rear side pillar are connected with the rear end of the upper yoke and the rear end of the lower yoke respectively, the upper ends and the lower ends of the main iron core pillars are connected with the middle of the upper yoke and the middle of the lower yoke respectively. The cross sections of the main iron core pillars are circular, the cross section of the front side pillar and the cross section of the rear side pillar are rectangular, and the longitudinal section of the upper yoke and the longitudinal section of the lower yoke are rectangular.
