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 the plurality of outer peripheral iron core portions, and coils wound onto the at least three iron cores. Gaps, which can be magnetically coupled, are formed between one of the at least three iron cores and another iron core adjacent thereto. The reactor includes cover parts which at least partially cover the iron cores and provide insulation from the coils.

摘要： A three-phase AC reactor according to an embodiment of the present invention includes an input and output terminal block; a peripheral iron core disposed under the input and output terminal block; and at least three iron-core coils each constituted of an iron core and a coil wound around the iron core, so as to contact an inner surface of the peripheral iron core or so as to be coupled to the inner surface. The at least three iron-core coils form gaps that can be magnetically coupled between two of the iron-core coils adjoining each other. The three-phase AC reactor includes a phase-based coil extending member unit that extends from coil end portions of the coils as base points to connection points of the input and output terminal block.

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.

摘要： A reactor includes a core body having an outer peripheral iron core, at least three iron cores contacting or coupled to an internal surface of the outer peripheral iron core, and coils wound on the iron cores. The reactor has a terminal base including terminals connected to the coils and connected to cables through current-carrying portions, and an electrical shock protection cover for covering the terminal base. The electrical shock protection cover includes a main portion for covering the current-carrying portions, and cable covering portions extending from the main portion to cable drawing directions so as to cover a part of each cable. The terminal base includes a main portion for supporting the current-carrying portions, and cable receiving portions in which passages are formed to pass the cables therethrough between the cable receiving portion and the cable covering portion.
