Three-phase AC reactor that can reduce magnetic flux leakage

摘要

A three-phase AC reactor according to the present invention includes a peripherally enclosing external core; at least three core coils being in contact with or connected to an interior of the external core, each of the core coils including a core and a coil wound around the core, and the adjoining core coils being magnetically connected through a gap; and a barrier fitted on an end portion of the external core so as to enclose side surfaces of the coils.
