Description

Technical Field

[0001] The utility model relates to the technical field of reactors, and specifically relates to a reactor tooling. Background Technique

[0002] Inductive reactors play a very important role in the power grid, and have the functions of suppressing harmonics, stabilizing voltage, current limiting protection, improving power factor, filtering and demagnetizing, balancing voltage, enhancing current, storing electric energy, limiting overcurrent and overvoltage to protect electrical equipment. Generally, the reactors used in the power grid work under high power conditions for a long time, and the temperature rise caused by power consumption and heat generation is the main factor determining its power upper limit. If the power continues to increase, the resulting temperature rise will cause burnout.

[0003] Traditional large reactors generally stack multiple layers of day-shaped magnetic cores, and the wire passes through the two openings of the day shape. In the traditional design, the middle column of the magnetic core generates the most heat, but this part is wrapped by the coil, resulting in difficult heat dissipation.

[0004] Therefore, we design a reactor tooling here. Content of the Utility Model

The trapezoidal frames are arranged on the outer side wall of the circular ring support in a circular array form, and the small head ends of the trapezoidal frames are connected to the outer side wall of the circular ring support;

[0008] The stack of magnetic chip blocks is formed by stacking several magnetic chips. The magnetic chips are in the shape of a rectangular frame, and one side wall of the rectangular frame is arc-shaped. The stack of magnetic chip blocks is arranged between two adjacent trapezoidal frames;

[0009] The copper coil is arranged inside the support skeleton and the stack of magnetic chip blocks, and is wound by passing one end of the copper wire through the middle holes of the trapezoidal frames and the stack of magnetic chip blocks in sequence. The two ends of the copper wire are exposed outside the support skeleton.

[0013] Preferably, the magnetic core is a silicon steel magnetic core or an amorphous magnetic core.

[0014] Preferably, the thickness of the large end of the trapezoidal frame is greater than the thickness of the small end.

[0015] Compared with the prior art, the present invention provides a reactor tooling with the following beneficial effects:

[0016] This utility model significantly improves heat dissipation performance by optimizing the reactor's structural design. In particular, the use of a ceramic support frame and aluminum nitride ceramic materials ensures stable operation of the reactor in high-temperature environments, preventing damage due to overheating.

[0017] In terms of structure, the rational design of the trapezoidal frame and circular bracket enhances the overall stability of the reactor. The material selection of the core and support frame further optimizes the efficiency of the reactor while reducing manufacturing costs.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] See also Figure 1 、 Figure 2 and Figure 3The reactor tooling described in this embodiment includes a support frame 1, a core block 2, and a copper coil 3. The core block 2 is arranged on the support frame 1 to form the core structure of the reactor.

[0026] The support frame 1 consists of a trapezoidal frame 11 and a circular bracket 12. The trapezoidal frames 11 are evenly arranged on the outer wall of the circular bracket 12 in the form of a circular array, and the small end of each trapezoidal frame 11 is tightly connected to the outer wall of the circular bracket 12 to ensure the stability and durability of the entire structure.

[0027] The core stack 2 is composed of multiple cores 21 stacked together. Each core 21 is shaped like a rectangular frame with one end having an arc-shaped sidewall. This design enhances the core's structural strength while reducing magnetic flux leakage. The core stack 2 is fixed between two adjacent trapezoidal frames 11 to ensure stable positioning during assembly.

[0028] The copper coil 3 is formed by repeatedly passing one end of a copper wire through the trapezoidal frame 11 and the center hole of the magnetic core block 2, forming a compact coil structure. The two ends of the copper wire are exposed on the outside of the support frame 1 (not shown) to facilitate connection to external circuits.

[0029] Example 2:

[0030] In this embodiment, the support frame 1 is preferably made of resin or ceramic. Ceramic support frames are more resistant to high temperatures and corrosion, and are suitable for high-temperature working environments. The preferred ceramic material is aluminum nitride ceramic, which has excellent thermal conductivity and mechanical strength, effectively improving the heat dissipation performance of the reactor.

[0031] Example 3:

[0032] The core stack 2 is preferably constructed from 5-10 cores 21 stacked together. This configuration ensures sufficient magnetic flux while controlling the overall height of the core stack. Silicon steel or amorphous materials are preferred, as these materials offer low hysteresis loss and high saturation flux density, further improving the reactor's operating efficiency.

[0033] Example 4:

[0034] In this embodiment, the thickness of the large end of the trapezoidal frame 11 is preferably designed to be greater than the thickness of the small end. Such a design can reduce the amount of material used and reduce manufacturing costs while ensuring structural strength. In addition, the thicker design of the large end of the trapezoidal frame 11 also helps to enhance the stability of the entire structure.

[0035] In summary, the reactor tooling of the present invention, through the rational design of the support frame, magnetic core stack, and copper coil structure and material selection, effectively addresses the heat dissipation deficiencies of conventional reactors and is suitable for the design and manufacture of high-power reactors. Those skilled in the art will appreciate that various modifications and adjustments to the aforementioned embodiments are possible without departing from the spirit and scope of the present invention, and such modifications are intended to be included within the scope of protection of the present invention.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
