Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and more specifically, to a capacitor control fixture and a capacitor fixture system. Background Technology

[0002] Large-size metal-cased DC dry-type capacitors are a key component of high-voltage flexible DC transmission and transformation systems, crucial for the stable operation of these systems. However, in the manufacturing of such capacitors using existing technologies, the metal casing is prone to unpredictable deformation due to the curing shrinkage of the internal materials and other physicochemical changes. This deformation not only affects the capacitor's external dimensions but, more importantly, can lead to uneven stress distribution between the core and the casing, thereby reducing the capacitor's electrical performance, such as high-voltage insulation and partial discharge performance.

[0003] Therefore, existing technologies have the problem of difficulty in controlling the deformation of capacitors. Utility Model Content

[0004] The main objective of this invention is to provide a capacitor control fixture and capacitor fixture system to solve the problem of difficulty in controlling capacitor deformation in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a capacitor control fixture is provided, comprising: at least two clamping plates arranged opposite to each other, each clamping plate having at least two limiting structures spaced apart along an arrangement direction perpendicular to the two clamping plates on its side closest to each other, and all the limiting structures forming a limiting space; and a fixing component, the fixing component being detachably connected to the two clamping plates respectively.

[0006] Furthermore, the limiting structure is a limiting protrusion, the protrusion direction of the limiting protrusion is the same as the thickness direction of the clamping plate, and the length of the limiting protrusion in the height direction of the clamping plate is the same as the height of the clamping plate.

[0007] Furthermore, the two limiting protrusions of the two clamping plates correspond one-to-one, and the line connecting the two corresponding limiting protrusions is parallel to the thickness direction of the clamping plate.

[0008] Furthermore, there is a clearance gap between the two corresponding limiting protrusions.

[0009] Furthermore, the length direction of the two limiting protrusions on the same clamping plate is the same as the height direction of the clamping plate.

[0010] Furthermore, an installation notch is provided on one side of the two limiting protrusions of the same clamping plate that are close to each other. The installation notch is located at the edge of the limiting protrusion to form a stepped structure at the edge of the limiting protrusion.

[0011] Furthermore, a groove is provided in the area between the two limiting protrusions of the clamping plate.

[0012] Furthermore, the two limiting protrusions of the same clamping plate are symmetrical about the centerline of the clamping plate, which is parallel to the height direction.

[0013] According to another aspect of the present invention, a capacitor tooling system is provided, including the capacitor control tooling described above.

[0014] Furthermore, the capacitor tooling system also includes a capacitor, which is positioned between the two clamping plates of the capacitor control tooling.

[0015] Applying the technical solution of this utility model, the capacitor control fixture in this application includes at least two clamping plates and a fixing assembly arranged opposite to each other. Each of the two clamping plates has at least two limiting structures spaced apart along a direction perpendicular to the arrangement of the two clamping plates on its side closest to each other, and all the limiting structures form a limiting space; the fixing assembly is detachably connected to each of the two clamping plates.

[0016] When using the capacitor control fixture of this application, the capacitor can be clamped by the two clamping plates and fixed by the fixing components. After the clamping plates have clamped the capacitor, they can be fixed by the fixing components, effectively preventing relative movement between the two clamping plates and ensuring the limiting effect of the capacitor control fixture on the capacitor, thereby achieving deformation control of the capacitor shell. Simultaneously, since the side of the two clamping plates that is close to each other also has a limiting structure, the capacitor control fixture of this application can also position the capacitor through the limiting structure, thereby ensuring the stability between the capacitor and the two clamping plates. Furthermore, this design allows for further control of capacitor deformation. Therefore, the capacitor control fixture of this application effectively solves the problem of difficulty in controlling capacitor deformation in the prior art. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0026] To address the problem of difficulty in controlling capacitor deformation in existing technologies, this application provides a capacitor control fixture and a capacitor fixture system.

[0027] like Figures 1 to 3 As shown, the capacitor control fixture in this application includes at least two clamping plates 10 arranged opposite to each other and a fixing assembly 20. The two clamping plates 10 have at least two limiting structures 11 arranged at intervals along a direction perpendicular to the arrangement of the two clamping plates 10 on their respective sides, and all the limiting structures 11 form a limiting space; the fixing assembly 20 is detachably connected to the two clamping plates 10 respectively.

[0028] When using the capacitor control fixture of this application, because it has clamping plates 10 and fixing components 20, the capacitor 30 can be clamped by the two clamping plates 10. After the clamping plates 10 have clamped the capacitor, the two clamping plates 10 can be fixed by the fixing components 20, thereby effectively preventing relative movement between the two clamping plates 10 and ensuring the limiting effect of the capacitor control fixture on the capacitor, so as to achieve deformation control of the capacitor shell. At the same time, since the side of the two clamping plates 10 that is close to each other also has a limiting structure 11, the capacitor control fixture of this application can also position the capacitor through the limiting structure 11, thereby ensuring the stability between the capacitor and the two clamping plates 10, and further controlling the deformation of the capacitor through this setting. Therefore, the capacitor control fixture of this application effectively solves the problem of difficulty in controlling the deformation of capacitors in the prior art.

[0029] Specifically, the limiting structure 11 is a limiting protrusion 111. The protrusion direction of the limiting protrusion 111 is the same as the thickness direction of the clamping plate 10, and the length of the limiting protrusion 111 in the height direction of the clamping plate 10 is the same as the height of the clamping plate 10. Technically, the design of the limiting protrusion 111 ensures that the deformation of the capacitor during the curing process is strictly limited within a preset range, avoiding performance degradation caused by excessive expansion or contraction. In principle, the limiting protrusion 111 is aligned with the thickness direction of the clamping plate 10, which can effectively disperse stress and prevent stress concentration from damaging the capacitor casing. In terms of effect, the technology in this embodiment, through the setting of the limiting protrusion 111, achieves uniform stress distribution of the capacitor during the curing process, further improving the insulation performance and partial discharge performance of the capacitor. In other embodiments, the shape and size of the limiting protrusion 111 can be changed to adapt to the manufacturing requirements of different capacitors and solve the stress control problem of specific capacitors during the curing process.

[0030] Furthermore, in this application, the fixing component 20 may include multiple screws and nuts, with the same screw passing through two clamping plates 10 in sequence and the nuts securing the two clamping plates 10 together. Of course, provided that the two clamping plates 10 can be fixed, the fixing component 20 in this application may also have other structures.

[0031] In this application, regarding the mating position of the fixing component 20 and the clamping plate 10, when the fixing component 20 includes multiple screws and nuts, the clamping plate 10 is provided with corresponding mounting holes that mate with the screws, and at least one mounting hole is provided on each side of the two limiting protrusions 111 of the same clamping plate 10 that are far apart from each other.

[0032] Preferably, at least one mounting hole is provided at each of the four corners of the clamping plate 10, meaning that the fixing component 20 can fix the four corners of the two clamping plates 10 respectively by using different screws and nuts.

[0033] Optionally, the two limiting protrusions 111 of the two clamping plates 10 correspond one-to-one, and the line connecting the corresponding two limiting protrusions 111 is parallel to the thickness direction of the clamping plate 10. Technically, this correspondence design ensures that the deformation of the capacitor is uniformly controlled during the curing process, avoiding uneven deformation caused by excessive stress on one side. In principle, the parallelism of the corresponding limiting protrusions 111 to the thickness direction of the clamping plate 10 ensures deformation control of the capacitor in all directions, improving the dimensional accuracy of the capacitor. In terms of effect, the technology in this embodiment, through the one-to-one correspondence of the limiting protrusions 111, achieves uniform deformation control of the capacitor during the curing process, further improving the dimensional stability and performance consistency of the capacitor. In other embodiments, the spacing and position of the limiting protrusions 111 can be adjusted to adapt to the size and deformation control requirements of different capacitors, solving the dimensional control problem of specific capacitors during the curing process.

[0034] Optionally, a clearance gap 12 is provided between the two corresponding limiting protrusions 111. By providing the clearance gap 12, the surface structure of the capacitor can be avoided, thereby preventing damage to the capacitor.

[0035] Optionally, the length direction of the two limiting protrusions 111 of the same clamping plate 10 is the same as the height direction of the clamping plate 10. This arrangement can effectively improve the limiting effect of the limiting protrusions 111 of the two clamping plates 10 on the capacitor.

[0036] Specifically, a mounting notch 112 is provided on one side of the two limiting protrusions 111 of the same clamping plate 10 that are close to each other. The mounting notch 112 is located at the edge of the limiting protrusion 111 to form a stepped structure at the edge of the limiting protrusion 111. That is, in this application, the mounting notch 112 is located at the connection between two adjacent surfaces of the limiting protrusion 111, thereby forming a stepped surface at the connection between the two adjacent surfaces. Furthermore, in this application, the mounting notch 112 is located at the end of the limiting protrusion 111 away from the clamping plate 10 on which it is located. Or, the mounting notch 112 is located at the end of the limiting protrusion 111 near the clamping protrusion on the other clamping plate 10 opposite to it. In addition, during use, the surface or edge of the capacitor can be made to cooperate with the stepped surface of the limiting protrusion 111, so that the stepped structure of the limiting protrusion 111 can play a role in limiting or positioning the capacitor.

[0037] Furthermore, it should be noted that the shape of the limiting protrusion 111 in this application can be a cuboid.

[0038] Specifically, a recessed groove 13 is provided in the area between the two limiting protrusions 111 on the clamping plate 10. Although the capacitor control fixture in this application controls the deformation of the capacitor, the capacitor can still deform under the action of the two clamping plates 10 and the fixing assembly 20, and the capacitor control fixture can control the deformation trend of the capacitor. Therefore, in this application, the recessed groove 13 effectively provides deformation space for the capacitor. Thus, in this application, the opening area of ​​the recessed groove 13 and the area of ​​the surface of one side of the corresponding capacitor can be approximately the same. Of course, in this application, the opening area of ​​the recessed groove 13 or the distance between the two limiting protrusions 111 on the same clamping plate 10 can be adaptively adjusted according to different actual usage requirements.

[0039] Optionally, the two limiting protrusions 111 of the same clamping plate 10 are symmetrical about the centerline of the clamping plate 10, which is parallel to the height direction. This arrangement can effectively ensure the stability of the capacitor clamping by the capacitor control fixture.

[0040] The capacitor tooling system in this application includes the capacitor control tooling described above.

[0041] Specifically, the capacitor tooling system also includes a capacitor 30, which is disposed between two clamping plates 10 of the capacitor control tooling. Furthermore, in this application, the thickness direction of the two clamping plates 10 is the same as the thickness direction of the capacitor. Simultaneously, the two clamping plates 10 clamp the capacitor along its thickness direction, or in other words, the two clamping plates 10 are located on both sides of the capacitor's thickness direction.

[0042] And, as Figure 2 and Figure 3 As shown, in this application, the capacitor 30 includes a housing 31, a capacitor core 32 disposed inside the housing, and a filling resin 33 filling the housing. The housing also has capacitor electrode terminals 34. Furthermore, in... Figure 2 In the diagram, the arrow points in the direction of the stress on the capacitor.

[0044] 1. Effectively solves the problem of difficulty in controlling capacitor deformation in existing technologies;

[0045] 2. Simple structure and stable performance.
