Four post conjugation reactors of three-phase

The utility model discloses a four post conjugation reactors of three-phase, its include one upper yoke, six around under iron yokes, one iron yokes and the one side column of coil not in the core leg that has the coil, the one, three around there being the core leg of coil to locate side by side between upper yoke and the well iron yokes, the iron yokes was with down between the iron yokes during three core leg around there being the coil was located side by side in addition, the side column of coil is not for the limit iron yokes and locate the six around the outside of the core leg that has the coil, the both ends of the side column of coil link to each other with iron yokes down with the upper yoke respectively, the iron yokes is continuous in the intermediate sum of side column. The utility model discloses four post conjugation reactors of three-phase is because the on the basis of at conventional three-phase reactor has increased the one side column, and the side column can have stronger inhibitory action to the common-mode signal for around there being the core leg of coil to provide the magnetic loop. Become the reactor design structure of upper and lower conjugation style simultaneously, compare with two independent reactors, not only saved the one iron yokes, also can design the iron yokes of sharing littleer.
