[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described by the present application are part of the embodiments of the present application, not all the embodiments.

[0017] As shown in Figures 1 to 3 An internal assembly structure of an intelligent capacitor, comprising a reactance 1, a capacitor 2 and a support plate 3 arranged inside the shell of the intelligent capacitor.

[0018] The reactance 1 and the capacitor 2 are arranged on the top surface of a bottom plate 4, the bottom of the capacitor 2 is connected to the bottom plate 4 by a screw, and the capacitor 2 is arranged in an upright state, the edge of the top of the capacitor 2 has a flange 21, as a general rule, the shell of the capacitor is usually formed by metal stamping, and the flange 21 of the top edge is formed when the shell is sealed.

[0019] The bottom surface of the rear end of the support plate 3 is provided with at least three legs 31, and the three legs 31 are located on the outer circumference of the capacitor 2. The middle section of the legs 31 is provided with a slot 311, which is engaged with the outer side of the flange 21 to limit the installation position of the support plate 3 on the capacitor 2. The support plate 3 and the top surface of the capacitor 2 are at a predetermined distance. A clamp 5 is fitted on the outside of the capacitor 2. The clamp 5 is pressed against the lower outer wall of the legs 31 to press the legs 31 against the capacitor 2, thereby achieving the purpose of fixing the support plate 3 on the capacitor 2. The front end of the support plate 3 extends above the reactor 1. The top surface of the support plate 3 is used to install the circuit board. Specifically, the circuit board is connected to the support plate 3 by screws. This design places the support plate 3 over the reactor 1 and capacitor 2, and utilizes the support plate 3 to mount the circuit board. This helps shorten the connection lines and simplify the wiring layout. Furthermore, by placing the capacitor 2, reactor 1, and circuit board inside the casing, the number of paths for the terminals to extend outwards is reduced, effectively simplifying the assembly process and further simplifying the wiring layout. The design utilizes the slot 311 on the support leg 31 to connect with the flange 21 of the capacitor 2. This not only serves as a limit but also allows the support plate 3 to be pre-fixed to the capacitor 2 during assembly, freeing the operator's hands to install the clamp 5. The connection between the slot 311 and the flange 21 also prevents the support leg 31 from sliding along the height of the capacitor 2, improving the stability of the support plate 3 mounting structure. Finally, the clamp 5 secures the support plate 3 to the capacitor 2, making the assembly and disassembly of the support plate 3 more convenient.

[0020] Preferred, such as Figures 1 to 3 As shown, the support plate 3 has through holes 32 for passing through the cables connecting the circuit board to the reactor 1 and the capacitor 2. This prevents the connecting cables from passing through the side of the support plate 3 and confines the connection within the through holes 32, which helps to improve the neatness of the wiring.

[0021] Preferably, the support leg 31 and the support plate 3 are integrally stamped and formed.

[0022] Preferred, such as Figure 3 As shown, the outer wall of the support leg 31 corresponding to the slot 311 protrudes outward relative to the outer wall of the lower end of the support leg 31. The protruding part can be used to limit the highest position of the clamp 5 and prevent the clamp 5 from falling upward.

[0023] Preferred, such as Figures 1 to 3 As shown, the lower end of the support leg 31 has an outwardly bent portion 312, and the clamp 5 is located above the bent portion 312. The bent portion 312 can effectively prevent the clamp 5 from separating from the support leg 31, thereby improving the stability of the support plate 3 installation structure.

[0024] Preferably, the legs 31 are arranged in a circular array along the circumference of the capacitor 2. Alternatively, as shown below... Figure 1 , Figure 3As shown in the scheme, the supporting legs 31 are arranged at the rear end of the supporting plate 3 and on both sides of the rear end, and the side of the rear end of the supporting plate 3 facing the front is not provided with the supporting leg 31, so as to facilitate the connection cable of the capacitor 2 to pass through the front of the supporting plate 3.

[0025] Preferably, as shown in the scheme, the electric reactance 1 is provided with a plurality of groups, and all the groups are arranged on the same mounting plate 11, and the mounting plate 11 is connected to the bottom plate 4 through screws. Figure 1 、 Figure 2 Preferably, as shown in the scheme, the electric reactance 1 is provided with a plurality of groups, and all the groups are arranged on the same mounting plate 11, and the mounting plate 11 is connected to the bottom plate 4 through screws.

[0026] Preferably, as shown in the scheme, the middle part of the bottom plate 4 is in an arched structure, and the two sides of the arched structure are connected to the bottom surface of the shell of the intelligent capacitor through screws. Figure 1 、 Figure 2 Preferably, as shown in the scheme, the middle part of the bottom plate 4 is in an arched structure, and the two sides of the arched structure are connected to the bottom surface of the shell of the intelligent capacitor through screws.

[0027] The above only describes the preferred embodiments of the present application, and does not mean that it is the only or limiting the present application. Those skilled in the art should understand that various changes or equivalent replacements made to the present application without departing from the scope of the present application, all belong to the scope of protection of the present application.
