Design method of circulation-free air-core reactor and circulation-free air-core reactor

The invention discloses a design method of a circulation-free air-core reactor and the circulation-free air-core reactor, and belongs to the technical field of reactor design, the circulation-free air-core reactor comprises a star frame arm, an envelope and a reactor coil, and the reactor coil is formed by winding N aluminum flat wires; the aluminum flat wires are independently wound on each star frame arm, each aluminum flat wire enters the next circle after being wound by only one Nth circle in each circle, and the N aluminum flat wires continue to be wound on the next layer of structure in the reverse direction after being wound into the single-layer structure according to the number of the wrapping and winding amplitude aluminum flat wires in the single-layer structure until the whole reactor coil is wound; the number of star frame arms, the number of the radial aluminum flat wires wrapped and wound in the single-layer structure and the number of layers of the axial aluminum flat wires wrapped and wound i
