[0012] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0013] like Figure 1-5 As shown, a novel structure of an air-core reactor comprises a fixed shaft 1, a limiting tube 2, a bottom outlet aluminum bar 3, a mold core ring 4, a limiting stay 5, a mold support 6, a fixing bolt 7, a binding belt 8, an upper inlet aluminum bar (overlapping with the bottom outlet aluminum bar, not shown in the figure), a lifting seat 9, an insulator mounting plate 10 and a support insulator 11; the limiting tube is sleeved on the fixed shaft, the bottom outlet aluminum bar and the upper inlet aluminum bar are respectively placed at the bottom and the top of the limiting tube, and the bottom outlet aluminum bar is fixed to the fixed shaft by tightening the nut. The aluminum bar for the wire and the upper aluminum bar for the wire outlet are fastened at both ends of the limiting tube. The core ring is composed of two half rings, which are fixed between the bottom aluminum bar for the wire outlet and the upper aluminum bar for the wire outlet by the fixing bolts. A plurality of limiting stays and mold-mounting stays are evenly distributed around the core ring. The coil is fixed between the limiting stays by binding belts. The top of the lifting seat is fixedly connected to the bottom aluminum bar for the wire outlet, the bottom of the lifting seat is fixedly connected to the insulator mounting plate, and the bottom of the insulator mounting plate is fixedly connected to the support insulator.

[0014] Use a fixed shaft to fix the limit tube and the aluminum bar of the inlet and outlet wires, use the neck fixing bolts to fix the core ring, and fix the limit stay and the mold stay with a binding belt to ensure the inner diameter of the coil. When winding, the vertical binding belt is tied through the binding groove. Other processes follow the winding process of the hollow reactor. In order to reduce the height of the reactor, the star frame of the reactor is changed to a single aluminum bar laid flat, and the center axis is omitted. The reactor has a small diameter and light weight, and is supported by a single insulator. The reactor is small in size and has a smaller winding radius. The general design inner diameter is between 120mm-240mm.

[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
