Description

Technical Field

[0001] This application relates to the technical field of superconducting cables, and particularly to a conductor skeleton, an inner conductor of a superconducting tube, a superconducting cable, and a conductor assembly method. Background Art

[0002] In the development process of superconducting technology, CICC (Cable-in-Conduit Conductor) conductors are widely used in large-scale superconducting magnets due to their excellent electrical performance and mechanical strength.

[0003] The traditional CICC structure is a conductor structure formed by twisting six CORC cables around a central skeleton. For example, six sub-cables with circular cross-sections are twisted around a circular copper skeleton. In this structural design, since the sub-cables will generate springback during the twisting process, the uneven spacing between adjacent sub-cables is caused, which in turn leads to unstable performance; in addition, the springback may also cause stress concentration, further affecting the mechanical strength and electrical performance of the conductor. At the same time, the design of the circular skeleton may also cause additional stress when the sub-cables are wound, affecting the durability and reliability of the conductor. Summary of the Invention

[0004] This application provides a conductor skeleton, an inner conductor of a superconducting tube, a superconducting cable, and a conductor assembly method to solve the problem in the prior art that springback occurs during the twisting of sub-cables around the central skeleton, resulting in uneven spacing between adjacent sub-cables and unstable performance of the conductor.

[0005] On the one hand, this application provides a conductor skeleton, including: A skeleton main body with a first guiding groove formed on its surface. The first guiding groove spirally extends from one end of the skeleton main body to the other end on the surface of the skeleton main body around the central axis of the skeleton main body; A guiding sleeve with an inner ring surface. The inner ring surface is provided with a second guiding groove, and the extension path of the second guiding groove is the same as that of the first guiding groove. By sleeving the guiding sleeve on the surface of the skeleton main body, the second guiding groove and the first guiding groove can be relatively arranged to jointly form a guiding channel.

[0006] In a possible design, the number of the second guiding grooves is equal to the number of the first guiding grooves. A first sliding surface is formed between adjacent two first guiding grooves, and all the first sliding surfaces are located on the same cylindrical surface; a second sliding surface is formed between adjacent two second guiding grooves, and all the second sliding surfaces are located on the same cylindrical surface.

[0007] In a possible design, the first guiding groove and the second guiding groove are respectively semi-cylindrical grooves, and the diameters of the first guiding groove and the second guiding groove are equal.

[0008] In a possible design, a stepped groove is provided at a position near the end of the first guiding groove, and the diameter of the stepped groove gradually decreases in the direction approaching the end of the first guiding groove.

[0009] In a possible design, the length of the guiding sleeve is less than 1 / 2 of the lead of the helix where the second guiding groove is located.

[0010] In a possible design, the guiding sleeve includes a first collar and a second collar. The first collar and the second collar can move from the middle position of the skeleton body to both ends respectively by rotating around the central axis of the skeleton body in opposite directions.

[0011] In a possible design, the first collar and the second collar are tapered sleeves.

[0012] On the other hand, the present application also provides a method for assembling a conductor. The conductor is assembled by using the conductor skeleton as described above. The method includes: Put the guiding sleeve on the skeleton body; Insert the sub-cable into the guiding channel formed by the first guiding groove and the second guiding groove; Rotate and move the guiding sleeve along the axial direction of the skeleton body towards the end of the skeleton body.

[0013] On yet another aspect, the present application also provides a superconducting tube inner conductor, which is made by using the conductor assembling method as described above.

[0014] On still another aspect, the present application also provides a superconducting cable, including the superconducting tube inner conductor as described above.

[0015] The beneficial effects of the present application are as follows: For the conductor skeleton of the present application, a first guiding groove is opened on the surface of the skeleton body, so that the first guiding groove spirally extends from one end of the skeleton body to the other end on the surface of the skeleton body around the central axis of the skeleton body. A second guiding groove is opened on the inner ring surface of the guiding sleeve, and the extending path of the second guiding groove is the same as that of the first guiding groove. When the guiding sleeve is sleeved on the skeleton body, the second guiding groove and the first guiding groove are arranged opposite to each other to jointly form a guiding channel. In this way, after the sub-cable passes through the guiding channel, by screwing the guiding sleeve on the surface of the skeleton body, the guiding sleeve can rotate around the central axis of the skeleton body and also move along the axial direction of the skeleton body, so that the sub-cable can be quickly spirally wound around the surface of the skeleton body along the first guiding groove, enabling the sub-cable to be better fixed and arranged during the twisting process, effectively improving the springback phenomenon, keeping the distance between adjacent sub-cables uniform, optimizing the stress distribution, improving the stability of the conductor performance. At the same time, through the cooperation of the guiding sleeve and the skeleton body, the difficulty of assembling the sub-cable and the skeleton body is greatly reduced, and the assembling speed is improved.

[0016] The conductor assembly method provided by this application, since the conductor is assembled using the conductor skeleton in this application, thus includes all the above advantages of the conductor skeleton at the same time.

[0017] The inner conductor of the superconducting tube provided by this application, since it is made by using the conductor assembly method as described above, thus includes all the above advantages of the inner conductor of the superconducting tube at the same time.

[0018] The superconducting cable provided by this application, since it includes the inner conductor of the superconducting tube in this application, thus includes all the above advantages of the inner conductor of the superconducting tube at the same time. Description of the Drawings

[0022] The following will clearly and completely describe the technical solutions of this application in combination with the embodiments. Obviously, the described embodiments are some embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0023] The following will be combined with Figures 1 - 4 , to describe the conductor skeleton, the inner conductor of the superconducting tube, the superconducting cable and the conductor assembly method provided in the embodiments of this application.

[0024] Referring to Figure 1 as shown, the conductor skeleton provided by the embodiment of the present application includes a skeleton main body 100 and a guiding sleeve 200. The skeleton main body 100 is generally cylindrical. A first guiding groove 110 is formed on the side wall of the skeleton main body 100. The first guiding groove 110 spirally extends from one end of the skeleton main body 100 to the other end around the central axis of the skeleton main body 100 on the side wall of the skeleton main body 100, thus forming a spiral groove. Specifically, the number of the first guiding grooves 110 is multiple. Each first guiding groove 110 is used to accommodate a sub-cable. The shape and size of the first guiding groove 110 match those of the sub-cable. For example, the number of the first guiding grooves 110 is six. The six first guiding grooves 110 are evenly distributed in a ring around the central axis of the skeleton main body 100. Each first guiding groove 110 spirally extends around the central axis of the skeleton main body 100 on the side wall of the skeleton main body 100. That is to say, six spiral grooves with equal pitches are formed on the side wall of the skeleton main body 100. A sub-cable is respectively arranged in each spiral groove, so that six sub-cables are evenly wound around the side wall of the skeleton main body 100. The guiding sleeve 200 is annular. The inner ring surface of the guiding sleeve 200 is a cylindrical surface. A second guiding groove 210 is formed on the inner ring surface of the guiding sleeve 200. The extending path of the second guiding groove 210 is the same as that of the first guiding groove 110. By sleeving on the surface of the skeleton main body 100, the guiding sleeve 200 can make the second guiding groove 210 and the first guiding groove 110 be oppositely arranged to jointly form a guiding channel 300.

[0025] Referring to Figure 2 、 Figure 3As shown, in some specific embodiments, the number of the second guiding grooves 210 is equal to that of the first guiding grooves 110. For example, the number of the first guiding grooves 110 and the second guiding grooves 210 is six respectively. Six guiding channels 300 are formed between the six first guiding grooves 110 and the six second guiding grooves 210. When assembling the sub-cables onto the skeleton body 100, six sub-cables can pass through the corresponding guiding channels 300 simultaneously. Then, while rotating the guiding sleeve 200, an axial force is applied to the guiding sleeve 200, so that the guiding sleeve 200 moves axially along the skeleton body 100 while rotating, thereby winding the six sub-cables around the corresponding first guiding grooves 110 simultaneously. A first sliding surface 120 is formed between two adjacent first guiding grooves 110, and all the first sliding surfaces 120 are located on the same cylindrical surface; a second sliding surface 220 is formed between two adjacent second guiding grooves 210, and all the second sliding surfaces 220 are located on the same cylindrical surface. Specifically, the diameter of the cylindrical surface where all the first sliding surfaces 120 are located is equal to or slightly smaller than the diameter of the cylindrical surface where the second sliding surfaces 220 are located. In this way, after the guiding sleeve 200 is sleeved on the surface of the skeleton body 100, the guiding sleeve 200 can be guided to move axially along the skeleton body 100 by making the second sliding surface 220 slide along the first sliding surface 120, so that the guiding sleeve 200 can quickly slide to any position of the skeleton body 100.

[0026] In other embodiments, the number of the second guiding grooves 210 is not equal to that of the first guiding grooves 110. For example, the number of the first guiding grooves 110 is six, and the number of the second guiding grooves 210 is one. In this way, when assembling the sub-cables onto the skeleton body 100, each time one sub-cable is made to pass through the guiding channel 300, and then while rotating the guiding sleeve 200, an axial force is applied to the guiding sleeve 200, so that the guiding sleeve 200 moves axially along the skeleton body 100 while rotating, thereby winding this sub-cable around the corresponding first guiding groove 110. Repeating this six times can wind all six sub-cables around the corresponding first guiding grooves 110.

[0027] In other embodiments, the number of the second guiding grooves 210 can also be half of that of the first guiding grooves 110. For example, the number of the first guiding grooves 110 is six, and the second guiding grooves 210 are three spaced apart. In this way, when assembling the sub-cables onto the skeleton body 100, each time three sub-cables can be made to pass through the guiding channel 300, and then while rotating the guiding sleeve 200, an axial force is applied to the guiding sleeve 200, so that the guiding sleeve 200 moves axially along the skeleton body 100 while rotating, thereby winding these three sub-cables around the corresponding first guiding grooves 110. Repeating this once can wind all six sub-cables around the corresponding first guiding grooves 110. In this way, while ensuring a relatively high assembling speed, the total friction force of the sub-cables on the guiding sleeve 200 can be reduced, making it easier for the guiding sleeve 200 to rotate and move on the skeleton body 100.

[0028] Using the technical solution provided by the above embodiments, by sleeving the guiding sleeve 200 on the skeleton main body 100, the second guiding groove 210 and the first guiding groove 110 are oppositely arranged to jointly form a guiding channel 300. After the sub-cable passes through the guiding channel 300, by screwing the guiding sleeve 200 on the surface of the skeleton main body 100, the guiding sleeve 200 can rotate around the central axis of the skeleton main body 100 and can also move along the axial direction of the skeleton main body 100. As a result, the sub-cable can be quickly spirally wound around the surface of the skeleton main body 100 along the first guiding groove 110, enabling the sub-cable to be better fixed and arranged during the twisting process, effectively improving the springback phenomenon, keeping the distance between adjacent sub-cables uniform, optimizing the stress distribution, improving the stability of the conductor performance. At the same time, through the cooperation of the guiding sleeve 200 and the skeleton main body 100, the difficulty of assembling the sub-cable and the skeleton main body 100 is greatly reduced, and the assembly speed is increased.

[0029] Referring to Figure 2 、 Figure 3 As shown, in some embodiments provided by the present application, the first guiding groove 110 and the second guiding groove 210 are respectively semi-cylindrical grooves, and the diameters of the first guiding groove 110 and the second guiding groove 210 are equal. Specifically, the diameter of the semi-cylindrical groove is equal to the diameter of the sub-cable. First, it can ensure that when the sub-cable is placed, the sub-cable can naturally adapt to the shape of the semi-cylindrical groove, avoiding stress concentration caused by improper installation. Second, half of the sub-cable located between the first guiding groove 110 and the second guiding groove 210 is in the first guiding groove 110, and the other half is in the second guiding groove 210. When the guiding sleeve 200 is screwed, the sub-cable is not easily disengaged from the first guiding groove 110 or the second guiding groove 210, thereby improving the assembly efficiency and success rate. Third, designing the first guiding groove 110 and the second guiding groove 210 as semi-cylindrical grooves respectively is also convenient for processing and forming, and for ensuring the structural strength of the skeleton main body 100 and the guiding sleeve 200 after turning and cutting.

[0030] Referring to Figure 2 As shown, in some embodiments provided by the present application, a stepped groove 130 is provided at a position of the first guiding groove 110 near the end. The stepped groove 130 includes multiple segments, and in the direction gradually approaching the end of the first guiding groove 110, the diameter of the corresponding segment of the stepped groove 130 gradually decreases. Thereby, it can adapt to the end structure of the sub-cable, enabling the inner wall of the stepped groove 130 to be in good contact with the end of the sub-cable, and ensuring that the center line of the sub-cable and the center line of the skeleton main body 100 are equidistant in the completed conductor, effectively reducing the possible additional stress and deformation during the conductor winding process, and improving the overall performance and service life of the conductor.

[0031] In some of these specific embodiments, a rounded chamfer is formed at the stepped connection between two adjacent segments of the stepped groove 130. After the chamfering treatment, the frictional force between the stepped groove 130 and the sub-cable can be reduced, making the installation and disassembly of the conductor more convenient and safe.

[0032] In some embodiments provided by the present application, the length of the guiding sleeve 200 is less than 1 / 2 of the lead of the helix where the second guiding groove 210 is located. In this way, it can be ensured that the overall shape of the second guiding groove 210 in the guiding sleeve 200 is not too curved, thus facilitating the passage of the sub-cable between the first guiding groove 110 and the second guiding groove 210.

[0033] Refer to Figure 1 As shown, in some embodiments provided by the present application, the guiding sleeve 200 includes a first collar 230 and a second collar 240. The structures of the first collar 230 and the second collar 240 are the same. The first collar 230 and the second collar 240 can move from the middle position of the skeleton body 100 towards both ends respectively by rotating around the central axis of the skeleton body 100 in opposite directions. Specifically, during assembly, first, the first collar 230 and the second collar 240 are respectively sleeved on the skeleton body 100 and both are moved to the central position of the skeleton body 100. Then, the sub-cable is passed between the first guiding groove 110 and the second guiding groove 210. Next, the first collar 230 on the left side is rotated counterclockwise to move the first collar 230 towards the left end of the skeleton body 100, and at the same time, the second collar 240 on the right side is rotated clockwise to move the second collar 240 towards the right end of the skeleton body 100. In this way, the assembly time can be saved and the efficiency can be improved.

[0034] Refer to Figure 4 As shown, in some embodiments provided by the present application, the first collar 230 and the second collar 240 are tapered sleeves. Specifically, the outer side surface of the tapered sleeve is a conical surface with a smaller diameter at one end and a larger diameter at the other end. During assembly, first, the first collar 230 and the second collar 240 are respectively sleeved on the skeleton body 100 and both are moved to the central position of the skeleton body 100, and the ends with smaller diameters are made to be close to each other. In this way, when the first collar 230 and the second collar 240 are screwed towards the ends, the ends with larger diameters can prevent the hand from slipping, and it is easier to apply a force towards the left end to the first collar 230 and a force towards the right end to the second collar 240, thereby improving the assembly efficiency.

[0035] In some of these specific embodiments, stripes are further provided on the outer side wall of the guiding sleeve 200. The stripes extend axially, thereby increasing the frictional force between the hand and the guiding sleeve 200 and preventing the hand from slipping when rotating, thus improving the assembly efficiency.

[0036] In some of these specific embodiments, a radial through-hole is provided in the guiding sleeve 200. A ball is disposed within the through-hole. At the end of the through-hole located on the inner ring surface, there is a spherical stop edge for blocking the ball to prevent it from falling. Internal threads are provided on the inner wall of the through-hole and a bolt is installed. A spring is provided between the bolt and the ball, and the two ends of the spring are respectively abutted against the bolt and the ball. By screwing the bolt, a part of the spherical surface of the ball protrudes out of the spherical stop edge. When the guiding sleeve 200 is rotated and displaced on the skeleton body 100, the rolling of the ball can reduce the frictional force between the guiding sleeve 200 and the skeleton body 100, thereby improving the assembly efficiency.

[0037] In some of these specific embodiments, the skeleton body 100 is processed from annealed brass or aluminum materials, which have good mechanical properties, excellent corrosion resistance, and good electrical conductivity, and can ensure the stability and reliability of the skeleton body 100 under different working environments. The guiding sleeve 200 is made of annealed brass material and processed by high-precision turning and wire cutting processes. This process not only ensures the dimensional accuracy and surface quality of the guiding sleeve 200, but also improves the overall strength and stability of the product. By strictly controlling the processing process parameters, high consistency of each component is ensured to adapt to different installation requirements and usage environments.

[0038] The embodiments of the present application also provide a conductor assembly method, which uses the conductor skeleton in the above embodiments to assemble the conductor. The method includes the following steps: Step 1: Slip the guiding sleeve 200 onto the skeleton body 100; Step 2: Insert the sub-cable into the guiding channel 300 formed by the first guiding groove 110 and the second guiding groove 210; Step 3: Rotate and displace the guiding sleeve 200 along the axial direction of the skeleton body 100 towards the end of the skeleton body 100.

[0039] In some of these specific embodiments, first slip the first collar 230 and the second collar 240 onto the skeleton body 100 respectively; then move the first collar 230 and the second collar 240 to the central position of the skeleton body 100; then insert the corresponding sub-cable into the guiding channel 300 formed by the corresponding first guiding groove 110 and the second guiding groove 210; finally, screw out the first collar 230 and the second collar 240 respectively towards the two ends of the skeleton body 100. Specifically, rotate the first collar 230 clockwise / counterclockwise and apply an axial force towards one end of the skeleton body 100 to move the first collar 230 towards one end of the skeleton body 100. At the same time, rotate the second collar 240 counterclockwise / clockwise and apply an axial force towards the other end of the skeleton body 100 to move the second collar 240 towards the other end of the skeleton body 100, thereby winding the sub-cable around the first guiding groove 110 on the surface of the skeleton body 100.

[0040] During the above assembly process, the position of the sub-cable can be adjusted quickly and accurately to better maintain the twist pitch of the sub-cable, and other auxiliary methods can also be used for fixation. After the skeleton body 100 and the sub-cable are assembled, the guiding sleeve 200 can be reused.

[0041] Through the above assembly method, effective guidance can be provided during the conductor assembly process, significantly improving the speed, safety, and success rate of the assembly.

[0042] In the embodiment of the present application, a superconducting tube inner conductor is also provided, which is made by using the conductor assembly method in the above embodiment.
