Description

Technical Field

[0001] This utility model relates to the field of particle accelerator technology, and more specifically to a pipe device for a particle accelerator. Background Technology

[0002] The particle accelerator's wiring harness is 10 meters long. Since all electrodes within the harness are suspended above a 450kV high voltage, a metal tube is used to ensure a uniform electric field. Given the high voltage level and the need for insulation to ground, the entire wiring harness is suspended within an insulating cavity. The design uses two 5-meter tubes joined together; however, the tube's diameter and length make it quite heavy, and the plug-in joint is prone to deformation at the joint, causing misalignment between the two sections. This could interfere with the particle accelerator's operation. The deformation also affects the insulation distance between the wiring harness and the insulating cavity, compromising the system's safety performance. Utility Model Content

[0003] The purpose of this invention is to provide a pipe device for particle accelerators, which solves the problem of misalignment when splicing two sections of wire bundle pipes in particle accelerators.

[0004] To achieve the above objectives, this utility model provides a conduit device for a particle accelerator, which is sleeved on the outside of the wire harness conduit of the particle accelerator to connect two spliced ​​sections of wire harness conduit and is supported between the outer tube and the splice of the two sections of wire harness conduit. The conduit device is coaxially arranged with the wire harness conduit and at least partially covers the splice of the two sections of wire harness conduit. The conduit device includes: At least two insulating sleeves, the at least two insulating sleeves being spaced apart along the radial direction of the wire harness conduit; and An insulating support is disposed between two adjacent insulating sleeves to separate and support the insulating sleeves.

[0005] Optionally, the insulating support is annular and has at least one through hole extending along the length of the wire harness conduit.

[0006] Optionally, the insulating support is provided with a plurality of through holes, which are evenly distributed at intervals along the circumferential direction.

[0007] Optionally, the number of insulating sleeves is at least three layers.

[0008] Optionally, the length of the insulating sleeve gradually increases from the inside to the outside along the radial direction of the wire harness conduit.

[0009] Optionally, the length of the innermost insulating sleeve ranges from 20cm to 24cm, and the outer diameter of the innermost insulating sleeve ranges from 15cm to 19cm. The length of the next innermost insulating sleeve ranges from 68cm to 72cm, and the outer diameter of the next innermost insulating sleeve ranges from 23cm to 27cm. The length of the third insulating sleeve ranges from 118cm to 122cm, and the outer diameter of the third insulating sleeve ranges from 35.4cm to 35.8cm.

[0010] Optionally, along the axial direction of the wire harness conduit, the length of the insulating support is less than the length of the insulating sleeve.

[0011] Optionally, the insulating supports are symmetrically distributed relative to the splice of the two wire harness conduits.

[0012] Optionally, the piping device further includes an inner support member, which is provided between the insulating sleeve and the wire harness pipe. The inner support member is annular and covers the joint of the two sections of the wire harness pipe.

[0013] Optionally, the insulating sleeve includes a sleeve made of DuPont paper material and first fixing rings disposed at both ends of the sleeve. The insulating first fixing rings are provided with mounting grooves to engage with both ends of the sleeve.

[0017] Explanation of reference numerals in the attached figures Detailed Implementation

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0019] In this embodiment of the utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positional relationships of the components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0020] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] Figure 1 This is a cross-sectional view of a partial structure of a pipe device according to one embodiment of the present invention. Figure 2 This is a side view of a conduit device according to one embodiment of the present invention. In this figure, the conduit device 1 is used to sleeve the outside of the wire harness conduit 2 of the particle accelerator to connect two spliced ​​sections of the wire harness conduit 2, and is supported between the outer tube 3 and the splice of the two sections of the wire harness conduit 2. The conduit device 1 is coaxially arranged with the wire harness conduit 2, and at least a portion of the conduit device 1 covers the splice of the two sections of the wire harness conduit 2. In one example of the present invention, the outer tube 3 is glued to the conduit device 1. The outer tube 3 provides a sealed protective cavity for the conduit device 1 and the wire harness conduit 2. The conduit device 1 effectively ensures the concentricity of the two sections of the wire harness conduit 2 when spliced, and improves the structural strength of the connection position. The device is simple and reliable.

[0022] Furthermore, the grounded outer tube 3 needs to effectively shield external electromagnetic noise from interfering with internal signals, while also suppressing the leakage of internally generated electric fields. To achieve effective shielding, the outer tube 3 body needs to maintain good conductive continuity. In this embodiment, the material of the outer tube 3 can be one of many known to those skilled in the art. In one example of this invention, the outer tube 3 can be made of aluminum. On the one hand, using aluminum to make the outer tube 3 is less expensive; on the other hand, the aluminum outer tube 3 is lighter and easier to install.

[0023] Since all electrodes of the internal wiring harness of the particle accelerator's wiring harness duct 2 are suspended above a 450kV high voltage, while the protective outer tube 3 is grounded, appropriate electrical insulation between them is required. In this embodiment, an insulated pipe device 1 is used to support the wiring harness duct 2 and the outer tube 3. By optimizing the structural design of the pipe device 1, while ensuring that the two sections of the wiring harness duct 2 are concentric, not only are the insulation requirements between the wiring harness duct 2 and the outer tube 3 met, but the size and weight of the entire device are also reduced as much as possible, minimizing space occupation.

[0024] like Figure 1 and Figure 2 In the illustrated embodiment, the conduit assembly 1 includes at least two insulating sleeves 11 and insulating supports 12. The at least two insulating sleeves 11 are spaced apart along the radial direction of the wire harness conduit 2, and the insulating supports 12 are disposed between adjacent insulating sleeves 11 to separate and support them. In particle accelerators, the wire harness within the conduit is typically subjected to extremely high voltages or has a high potential difference with the external environment. Using a single insulating sleeve 11 would result in the entire enormous potential difference being borne by a single insulator, easily leading to insulation breakdown. With a multi-layered nested structure, under high voltage, current easily creeps along the surface of the insulator, forming flashover discharge. The insulating supports 12 separate adjacent insulating sleeves 11, forcing the current path to bypass these supports, increasing the effective creepage distance, and thus effectively suppressing surface flashover.

[0025] like Figure 4 As shown, in this embodiment, the insulating support 12 is annular and has at least one through hole extending along the length of the wire harness conduit 2. While meeting mechanical strength requirements, the through hole effectively reduces the weight of the component. Simultaneously, during operation of the conduit device 1, the space between the outer tube 3 and the wire harness conduit 2 allows for the flow of insulating medium to improve insulation performance; the through hole facilitates the passage of this insulating medium.

[0026] Furthermore, the number of through holes can be multiple, as is known to those skilled in the art. The insulating support 12 is provided with multiple through holes, which are evenly distributed at intervals along the circumferential direction.

[0027] In this embodiment, the number of insulating sleeves 11 can be any of the values ​​known to those skilled in the art. In one example of this invention, the number of insulating sleeves 11 is at least three layers.

[0028] To achieve high voltage resistance, the length of the insulating sleeve 11 gradually increases from the inside to the outside along the radial direction of the wire harness conduit 2. In this embodiment, the length of the multiple insulating sleeves 11 is designed to gradually increase from the inside to the outside, and the entire conduit device 1 is distributed in a "pyramid" structure in the radial direction. Through the gradient distribution of the insulating sleeves 11, the creepage distance is improved, the gradient optimization of the high voltage electric field is achieved, high voltage discharge is avoided, and the insulation protection at the splicing position of the wire harness conduit 2 is improved.

[0029] Considering that the insulating sleeve 11 needs to be reasonably distributed inside the outer tube 3, such as Figure 3 As shown, the number of insulating sleeves 11 can be three. Specifically, the length of the innermost insulating sleeve 11 ranges from 20cm to 24cm, and the outer diameter ranges from 15cm to 19cm. The length of the next innermost insulating sleeve 11 ranges from 68cm to 72cm, and the outer diameter ranges from 23cm to 27cm. The length of the third insulating sleeve 11 ranges from 118cm to 122cm, and the outer diameter ranges from 35.4cm to 35.8cm.

[0030] The multi-layered nested structure of the progressively increasing insulating sleeves 11 increases the necessary path length for current creepage along the surface, resulting in a longer creepage distance and effectively suppressing surface flashover. By precisely controlling the dimensions (including outer diameter, thickness, and axial length) of each insulating sleeve and the annular insulating support, the highest breakdown voltage is achieved in the most compact overall structure.

[0031] The dimensions of the insulating sleeve 11 can be any of the values ​​known to those skilled in the art. In a preferred embodiment of this invention, the innermost insulating sleeve 11 has a length of 22cm and an outer diameter of 16cm, the next innermost insulating sleeve 11 has a length of 72cm and an outer diameter of 25cm, and the third insulating sleeve 11 has a length of 120cm and an outer diameter of 35.6cm.

[0032] Furthermore, along the axial direction of the wire harness conduit 2, the length of the insulating support 12 is less than the length of the insulating sleeve 11, which can reduce the overall weight of the conduit assembly 1.

[0033] In this embodiment, the distribution of the insulating support members 12 outside the wire harness conduit 2 can be varied and known to those skilled in the art. In one example of this invention, the insulating support members 12 are symmetrically distributed relative to the joint of the two sections of the wire harness conduit 2. Exemplarily, two annular insulating support members 12 are provided between two adjacent insulating sleeves 11. The two annular insulating support members 12 are symmetrical with respect to the joint position of the wire harness conduit 2. The symmetrical distribution of the entire conduit device 1 can uniformly transfer the load between the outer tube 3 and the wire harness conduit 2, which effectively avoids excessive stress concentration in certain parts, thereby protecting the conduit device 1 and the internal wire harness conduit 2. In particular, the symmetrical distribution design can optimize the distribution of the high-voltage electric field, avoid local high-voltage discharge, and improve safety.

[0034] To improve the stability of the connection between the two sections of wire harness conduit 2, in this embodiment, the conduit device 1 further includes an inner support member 13, which is positioned between the insulating sleeve 11 and the wire harness conduit 2. The inner support member 13 is annular and covers the joint of the two sections of wire harness conduit 2. The use of the inner support member 13 further enhances the structural strength of the connection point of the wire harness conduit 2. The axial length of the inner support member 13 is less than the length of the insulating sleeve 11, facilitating the installation and fixing of the two connected sections of wire harness conduit 2. Simultaneously, the inner support member 13, together with the multi-layer insulating sleeve 11, forms a pyramid structure, optimizing the distribution of the high-voltage electric field.

[0035] In this embodiment, the material of the insulating sleeve 11 can be one of many known to those skilled in the art. In one example of this invention, the insulating sleeve 11 can be made of polytetrafluoroethylene (PTFE). Using PTFE for molding ensures the structural strength of the connection. Alternatively, the insulating sleeve 11 can be made of paper, which is lighter and has lower manufacturing costs than PTFE.

[0036] Furthermore, the insulating sleeve 11 is formed by winding insulating paper. In this embodiment, the insulating sleeve 11 may include a sleeve made of DuPont paper and first retaining rings (not shown) disposed at both ends of the sleeve. The insulating first retaining ring is provided with mounting grooves to engage with the two ends of the sleeve. The use of the first retaining ring and the paper in conjunction ensures the shape of the paper tube while overcoming its lack of mechanical strength. The first retaining ring may be made of polytetrafluoroethylene.

[0037] Through the above technical solution, this utility model provides a conduit device for a particle accelerator. This conduit device achieves splicing and insulation protection of the wire harness conduit through an insulating sleeve and an insulating support. The conduit device is fitted over the splicing point of two sections of wire harness conduit, ensuring concentricity. The size design of the insulating sleeve increases the creepage distance, effectively suppressing surface flashover and preventing insulation breakdown. The insulating support provides mechanical support. This structure is simple and reliable, ensuring both concentricity of the conduit and insulation safety under high voltage.
