Air-core reactor coil and air-core reactor using same

The utility model relates to the field of coils of inductors, in particular to an air-core reactor coil and an air-core reactor using the same. An air-core reactor comprises a shell, an air-core reactor coil is arranged in the shell, the air-core reactor coil comprises a plurality of sets of concentrically-arranged coils, a heat dissipation air channel extending in the axial direction is arranged between every two radially-adjacent coils, the coils are of a segmented structure in the axial direction, independent coil segments are formed, each coil segment is provided with an independent packaging structure, and the packaging structure is arranged in the shell. Every two adjacent independent coil segments are supported and separated through the corresponding interval supporting structure, the coil segments of the same coil are connected in series, and the problem that an existing air-core reactor is poor in heat dissipation effect is solved. 本实用新型涉及电感器的线圈领域，具体涉及一种空心电抗器线圈及使用该线圈的空心电抗器。一种空心电抗器，包括壳体，壳体内设置有空心电抗器线圈，
