    摘要： A reactor includes a core body including an outer peripheral iron core, at least three iron cores contacting to an internal surface of the outer peripheral iron core, and coils wound on the iron cores. A gap is formed between one and another of the iron cores adjacent each other, so as to be magnetically connectable therethrough. The reactor has a terminal base connected to cables through current carrying portions, as well as connected to the coils, and an electrical shock prevention cover for covering the terminal base. The electrical shock prevention cover has openings for passing the cables connected to the terminals therethrough. The terminal base has a plate that blocks at least a part of each opening to prevent a finger from touching the current carrying portion while the cables are connected to the terminals and which is detachable in accordance with the thickness of the cables.

    摘要： A core body of a reactor includes an outer peripheral iron core composed of a plurality of outer peripheral iron core portions, at least three iron cores coupled to inner surfaces of the plurality of outer peripheral iron core portions, and coils. Gaps, which can be magnetically coupled, are formed between one iron core and another iron core adjacent thereto. The reactor further includes a fixture which extends through the interior of the core body in a region between the outer peripheral iron core and the gaps to fasten opposite ends of the at least three iron cores to each other.

    摘要： A three-phase reactor includes an outer peripheral iron core for surrounding the outer periphery of the three-phase reactor, and at least three iron core coils, which are in contact with or coupled to the inner surface of the outer peripheral iron core. The at least three iron core coils includes iron cores and coils wound around the iron cores. Gaps, which can be magnetically coupled, are each formed between two adjacent ones of the iron cores. The three-phase reactor further includes a vibration suppressing structure part disposed in the vicinity of the gaps so as to reduce vibrations occurring at the gaps.
