[0022] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0024] Specifically, Figure 3-4 As shown, an embodiment of the present invention provides a light reactor, including: an enclosure 1, a star frame 2, a wiring terminal 3, a pillar 4 and a base 5. There are multiple enclosures 1, the radius of the multiple enclosures 1 is different, and they are coaxially arranged in sequence according to the size of the radius, and the adjacent enclosures are bonded together by the insulating layer of the dipped glue; there are two star frames 2, one of which is fixed on the top of the enclosure 1, and the other is fixed on the bottom of the enclosure 1; there are two wiring terminals 3, each of which is respectively arranged on the outside of any one arm of one of the star frames 2; the pillar 4 is arranged at the bottom of the star frame 2 located at the bottom of the enclosure 1; the base 5 is arranged at the bottom of the pillar.

[0025] In the present invention, the encapsulation uses a multi-layer cylindrical parallel structure, and multiple encapsulations are sequentially bonded according to the size of the radius by glue bonding, so that the struts can be pulled out of the traditional encapsulation, and the solidified colloid is used to replace the struts, thereby greatly reducing the overall weight of the reactor, and at the same time making the stability and firmness between the encapsulations better, so as to achieve the lightweight of the reactor under the condition of unchanged performance. At the same time, the reactor of the present invention reduces the heat dissipation area covered by the struts of the transmission reactor itself on the encapsulation 1, so that the heat dissipation effect of the lightweight reactor is better.

[0026] In this embodiment, the package 1 includes a plurality of conductors 1-3, all of which are evenly distributed in a matrix in the longitudinal section of the package 1, and the number of rows in the matrix is ​​an even number; all of the conductors 1-3 are grouped in pairs from top to bottom, and the conductors in each group are twisted together to form a stranded wire, and each stranded wire is wrapped by an inner insulating layer 1-1, and the longitudinal section edge of the inner insulating layer 1-1 is rectangular; the outer sides of the stranded wires arranged in sequence are wrapped by an outer insulating layer 1-2.

[0027] Meanwhile, in this embodiment, the inner insulating layer 1-1 is an insulating film or insulating paint dipped in glue. When the inner insulating layer 1-1 is an insulating film dipped in glue, the inner insulating layer 1-1 is a polyimide film, and the number of layers of the polyimide film is between 0 and 3. Meanwhile, in this embodiment, the outer insulating layer 1-2 is a non-woven fabric dipped in glue, polyester glass tape or alkali-free glass tape.

[0028] In the above technical solution, the glue is used to soak the package 1 and the stranded wire, so that the inner insulating layer 1-1, the outer insulating layer 1-2 and the stranded wire are completely compatible, and the glue can reach each wire 1-3, and the whole becomes one after solidification, which can greatly reduce the noise and vibration of the air-core reactor, so that the wires 1-3 are closely fitted during operation, and no vibration is generated, thereby reducing the noise during operation and improving the working stability of the reactor.

[0029] In this embodiment, the outer surface of the outermost package 1 is coated with acrylic polyamine urethane enamel and PRTV glue.

[0030] In this embodiment, the envelope 1 is fixedly connected to the star-shaped frames 2 at the upper and lower ends thereof to form a whole. During the manufacturing process, the envelope 1 is cured at high temperature to form a whole.

[0031] In this embodiment, the outer surface of the outermost package 1 is provided with glass fibers, so that the reactor of the present invention can be similar to the traditional reactor in appearance.

[0032] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
