Description

Technical Field

[0001] The present invention relates to the field of nuclear fusion technology, and in particular to a superconducting cable bending correction device and correction method, and a nuclear fusion device. Background Art

[0002] Superconducting cables are widely used in fields such as nuclear fusion experimental devices. Due to structural requirements, the cables are often arranged in multi-dimensional bends within magnet and feeder systems. Existing bending methods primarily utilize mechanical bending. However, due to the unique characteristics of superconducting cable materials, the bending process can experience springback—the elastic deformation recovers after unloading, causing the actual bending angle to deviate from the intended one. This angular springback can affect the accuracy of superconducting cable placement, and thus the performance of magnet and feeder systems.

[0003] In order to solve the above problems, some compensation measures have been adopted in the existing technology, such as pre-calculating the rebound amount and performing over-bending during bending, etc., but there are the following defects: on the one hand, a large amount of test data support is required and it is difficult to adapt to changes under different working conditions; on the other hand, the bending angle deviation is measured after bending, and the parts with errors are corrected using correction tooling. This solution is complicated to operate, the measurement and correction cycle is long, and there are other size, shape and position deviations caused by the correction. Summary of the Invention

[0004] The present invention aims to at least partially address one of the technical problems in the related art. To this end, one objective of the present invention is to provide a superconducting cable bending correction device that enables real-time automatic bending and rotation correction, has high correction efficiency, is adaptable to different operating conditions, and can improve the bending accuracy and consistency of superconducting cables, thus meeting the high-precision requirements for superconducting cable routing in fields such as nuclear fusion devices.

[0005] A device for correcting superconducting cable bending according to an embodiment of the first aspect of the present invention includes:

[0006] A cable bending device, comprising a guide support mechanism, a straightening mechanism, a rotating mechanism, and a bending mechanism for sequentially passing a superconducting cable horizontally and in the same direction, and a control processing module for controlling the feeding of the straightening mechanism, the rotation of the rotating mechanism, and the start and stop of the bending mechanism; the guide support mechanism is used to guide and support the superconducting cable, the straightening mechanism is used to straighten and feed the superconducting cable, the rotating mechanism is used to rotate the superconducting cable, and the bending mechanism is used to bend the superconducting cable;

After the bending correction, the bending mechanism releases the superconducting cable. Thereafter, the straightening mechanism starts feeding the superconducting cable according to a predetermined length and stops feeding. The rotating mechanism clamps the superconducting cable for rotation. After the rotation is completed, the rotating mechanism releases the superconducting cable, and the detection component detects the rotation angle deviation value of the superconducting cable and sends the rotation angle deviation value to the control processing module. If the rotation angle deviation exceeds a preset rotation tolerance value, the control processing module controls the rotating mechanism to perform rotation correction on the superconducting cable. After the rotation correction, the rotating mechanism releases the superconducting cable.

[0010] The superconducting cable bending correction device of the first embodiment of the present invention has the following advantages: on the one hand, by setting the detection component, the bending angle deviation value and the rotation angle deviation value of the superconducting cable during the bending and rotation processes can be measured in real time respectively; when the bending angle deviation exceeds the preset bending tolerance value, the control processing module automatically controls the bending mechanism to perform bending correction on the superconducting cable; when the rotation angle deviation exceeds the preset rotation tolerance value, the control processing module automatically controls the rotation mechanism to perform rotation correction on the superconducting cable, thereby realizing real-time automatic correction of the superconducting cable, with high correction efficiency and The invention effectively solves the problem of angular deviation caused by the rebound phenomenon in the bending of superconducting cables in the prior art. On the other hand, there is no need to conduct a large number of experiments in advance to obtain the rebound amount data, nor is there a need to adopt compensation measures such as over-bending. The device can directly perform correction based on the angle deviation value measured in real time, thereby improving the flexibility and adaptability of the correction and meeting the needs under different working conditions. On the other hand, the data detected by the detection component is accurate and reliable, which improves the accuracy of measurement and control. In addition, the data processing process of the detection component and the control processing module is efficient, which improves the efficiency of measurement and control, and is conducive to realizing the automation and intelligence of the superconducting cable bending.

DETAILED DESCRIPTION

[0042] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0043] The following combination Figures 1 to 4 The following describes a superconducting cable bending correction device 1000 and correction method, and a nuclear fusion device according to an embodiment of the present invention.

[0044] like Figures 1 to 4 As shown, a superconducting cable bending correction device 1000 according to an embodiment of the first aspect of the present invention includes a cable bending device 1 and a detection component 2.

[0045] Specifically, the cable bending device 1 includes a superconducting cable 3 provided with a horizontal and unidirectional (eg Figure 1 The guide and support mechanism 11, straightening mechanism 12, rotating mechanism 13, bending mechanism 14, and a control processing module 15 for controlling the feed of the straightening mechanism 12, the rotation of the rotating mechanism 13, and the start and stop of the bending mechanism 14 are sequentially passed through (in the straight line direction shown from left to right). The guide and support mechanism 11 is used to guide and support the superconducting cable 3. Specifically, the guide and support mechanism 11 provides horizontal support for the superconducting cable 3 and guides the superconducting cable 3 toward the straightening mechanism 12. The straightening mechanism 12 is used to straighten and feed the superconducting cable 3. Specifically, the straightening mechanism 12 provides power to feed the superconducting cable 3, allowing the superconducting cable 3 to pass through the rotating mechanism 13 and bend the bending mechanism 14. Furthermore, the straightening mechanism 12 straightens the superconducting cable 3. The rotating mechanism 13 rotates the superconducting cable 3 to enable multi-dimensional bending. The bending mechanism 14 bends the superconducting cable 3.

[0046] The detection assembly 2 is disposed on the bending mechanism 14 and is used to detect in real time the bending angle deviation of the superconducting cable 3 after being bent by the bending mechanism 14 and transmit the bending angle deviation value to the control processing module 15. It is also used to detect in real time the rotation angle deviation value of the superconducting cable 3 after being rotated by the rotating mechanism 13 and transmit the rotation angle deviation value to the control processing module 15. The detection assembly 2 enables real-time measurement of the bending angle deviation value of the superconducting cable 3 during the bending process and the rotation angle deviation value during the rotation process, allowing the control processing module 15 to control the bending mechanism 14 to perform real-time bending correction on the superconducting cable 3 and to facilitate real-time rotation correction control of the rotating mechanism 13, thereby improving the real-time performance and accuracy of the bending and rotation corrections.

[0047] When the bending angle deviation exceeds the preset bending tolerance, the control processing module 15 controls the bending mechanism 14 to perform bending correction on the superconducting cable 3. When the rotation angle deviation exceeds the preset rotation tolerance, the control processing module 15 controls the rotation mechanism 13 to perform rotation correction on the superconducting cable 3. By providing the detection assembly 2, the bending angle deviation and rotation angle deviation of the superconducting cable 3 during bending and rotation can be measured in real time. The control processing module 15 controls the bending mechanism 14 to perform bending correction on the superconducting cable 3 in real time, and controls the rotation mechanism 13 to perform rotation correction on the superconducting cable 3 in real time, thereby improving the real-time performance and accuracy of bending and rotation correction.

[0048] The working principle of the superconducting cable bending correction device 1000 of the first embodiment of the present invention is as follows: the superconducting cable 3 is placed on the guide support mechanism 11 and straightened by the straightening mechanism 12. The straightened superconducting cable 3 passes through the rotating mechanism 13. When the section to be bent of the superconducting cable 3 reaches the bending station of the bending mechanism 14, the straightening mechanism 12 stops feeding; the bending mechanism 14 bends the section to be bent; after the bending is completed, the bending mechanism 14 releases the superconducting cable 3 to obtain the bent section, the detection component 2 detects the bending angle deviation value of the bent section and sends the bending angle deviation value to the control processing module 15; if the bending angle deviation exceeds the preset bending tolerance value, , the control processing module 15 controls the bending mechanism 14 to perform a bending correction on the bending section. After the bending correction, the bending mechanism 14 releases the superconducting cable 3. The straightening mechanism 12 then feeds the superconducting cable 3 as scheduled and stops feeding. The rotating mechanism 13 clamps the superconducting cable 3 and rotates it. After the rotation is complete, the rotating mechanism 13 releases the superconducting cable 3. The detection assembly 2 detects the rotation angle deviation of the superconducting cable 3 and sends it to the control processing module 15. If the rotation angle deviation exceeds the preset rotation tolerance, the control processing module 15 controls the rotating mechanism 13 to perform a rotation correction on the superconducting cable 3. After the rotation correction, the rotating mechanism 13 releases the superconducting cable 3. The superconducting cable 3 is then fed again, and the above steps are repeated for the next bending operation, thereby achieving multi-dimensional bending of the superconducting cable 3.

[0049] The superconducting cable bending correction device 1000 of the first embodiment of the present invention has the following advantages: on the one hand, by setting the detection component 2, the bending angle deviation value and the rotation angle deviation value of the superconducting cable 3 during the bending and rotation processes can be measured in real time respectively. When the bending angle deviation exceeds the preset bending tolerance value, the control processing module 15 automatically controls the bending mechanism 14 to perform bending correction on the superconducting cable 3. When the rotation angle deviation exceeds the preset rotation tolerance value, the control processing module 15 automatically controls the rotation mechanism 13 to perform rotation correction on the superconducting cable 3, thereby achieving real-time automatic correction of the superconducting cable 3 with high correction efficiency. The present invention effectively solves the problem of angular deviation caused by springback during bending of the superconducting cable 3 in the prior art. Furthermore, there is no need to conduct extensive pre-tests to obtain springback data, nor is there any need to adopt compensation measures such as overbending. Correction can be performed directly based on the angular deviation values ​​measured in real time, improving the flexibility and adaptability of correction and meeting the requirements of different working conditions. Furthermore, the data detected by the detection component 2 is accurate and reliable, improving the accuracy of measurement and control. Furthermore, the data processing process of the detection component 2 and the control processing module 15 is efficient, improving the efficiency of measurement and control, and facilitating the automation and intelligentization of the bending of the superconducting cable 3. In summary, the superconducting cable bending correction device 1000 of the first embodiment of the present invention can monitor the bending angular deviation and rotational angular deviation of the superconducting cable 3 in real time, and automatically perform bending and rotation correction on the bending angular deviation and rotational angular deviation, effectively solving the problem of angular deviation caused by springback during bending of the superconducting cable 3 in the prior art. It improves the accuracy and consistency of superconducting cable 3 fabrication and meets the high-precision requirements for superconducting cable 3 deployment in fields such as nuclear fusion devices.

[0050] In some embodiments, the guide support mechanism 11 includes a guide support platform 111 and multiple guide units 112. The multiple guide units 112 are installed on the guide support platform 111 at intervals along the feed direction. Each guide unit 112 includes a supporting rotating wheel 1121 and position-limiting rotating posts 1122 located at both ends of the supporting rotating wheel 1121. The axis of the supporting rotating wheel 1121 is perpendicular to the feed direction, and the axis of the position-limiting rotating posts 1122 is perpendicular to the axis of the supporting rotating wheel 1121. The superconducting cable 3 is placed on the supporting rotating wheel 1121 and is restrained by the position-limiting rotating posts 1122. The friction between the superconducting cable 3 and the guide units 112 is low.

[0051] In some embodiments, the straightening mechanism 12 includes a straightening support platform 121 and multiple straightening wheel groups 122. The multiple straightening wheel groups 122 are arranged in close proximity along the feed direction. Each straightening wheel group 122 consists of two straightening wheels 1221 arranged in a direction perpendicular to the feed direction. The superconducting cable 3 passes through the channel formed between the two straightening wheels 1221 of the multiple straightening wheel groups 122, and is straightened by the straightening wheel groups 122 and provided with feed power. The side of the straightening wheel 1221 has an annular groove with an arc-shaped cross section to adapt to the surface of the superconducting cable 3 and limit the position of the superconducting cable 3. The straightening wheel 1221 can be replaced according to the different diameters of the superconducting cable 3.

[0052] In some embodiments, the straightening mechanism 12 is provided with a feed length sensor 123 for measuring the feed length of the superconducting cable 3. The feed length sensor 123 communicates with the control processing module 15 so as to transmit the real-time measured feed length data of the superconducting cable 3 to the control processing module 15. When the feed length data reaches a preset feed length value, the control processing module 15 controls the straightening mechanism 12 to stop feeding so that the bending mechanism 14 bends the superconducting cable 3 or the rotating mechanism 13 rotates the superconducting cable 3.

[0053] The feed length sensor 123 can be connected to one of the straightening wheel groups 122 . The feed length sensor 123 can sense the number of rotations of the straightening wheel 1221 , and thus the number of rotations of the straightening wheel 1221 can be used to obtain the feed length of the superconducting cable 3 .

[0054] The rotating mechanism 13 is provided with a rotating fixture 133 for clamping or releasing the superconducting cable 3. Specifically, the rotating mechanism 13 includes a rotating support 131, a rotating mechanism body 132 fixed to the lower rotating support 131, and a rotating fixture 133 disposed on the rotating mechanism body 132. The superconducting cable 3 can pass through the rotating mechanism body 132, which provides rotational power. When rotation is required, the rotating fixture 133 clamps the superconducting cable 3; when rotation is not required, the rotating fixture 133 releases the superconducting cable 3. Both the rotating mechanism body 132 and the rotating fixture 133 are controlled by a control processor 151.

[0055] The bending mechanism 14 includes a bending mold 142, a bending guide block 143 and a bending clamp 144; the bending mold 142 is horizontally arranged on one side of the rotation axis of the rotating mechanism 13, and the bending guide block 143 and the bending clamp 144 are horizontally arranged on the other side of the rotation axis and the bending guide block 143 is located between the rotating mechanism 13 and the bending clamp 144. The bending guide block 143 is used to limit and guide the superconducting cable 3 to contact tangentially with the bending mold 142 when it is fed into the bending mold 142; the bending clamp 144 is used to press the superconducting cable 3 onto the bending mold 142.

[0056] When the bending mechanism 14 bends the superconducting cable 3, the superconducting cable 3 is restricted to tangential contact with the bending mold 142 by the bending guide block 143, and the superconducting cable 3 is pressed against the circumferential side of the bending mold 142 by the bending clamp 144, so that the superconducting cable 3 is closely attached to the circumferential side of the bending mold 142, thereby realizing the bending of the superconducting cable 3.

[0057] Specifically, the bending mechanism 14 also includes a bending support platform 141, on which a bending die 142, a bending guide block 143, and a bending fixture 144 are mounted. The bending die 142 is detachably fixed to the bending support platform 141 and can be replaced with bending dies 142 of different sizes depending on the outer diameter of the superconducting cable 3. The bending die 142, bending guide block 143, and bending fixture 144 are each provided with an annular groove with an arcuate cross-section that conforms to the superconducting cable 3.

[0058] Optionally, the bending fixture 144 may be a pneumatic fixture.

[0059] In some embodiments, the detection component 2 includes a first high-speed camera module 21, a second high-speed camera module 22 and a data processing module 23; the first high-speed camera module 21 and the second high-speed camera module 22 communicate with the data processing module 23; the first high-speed camera module 21 is used to capture in real time a bent image of the superconducting cable 3 after being bent by the bending mechanism 14, and accordingly, the data processing module 23 identifies the bent image and calculates the bending angle deviation value and sends the bending angle deviation value to the control processing module 15; the second high-speed camera module 22 is used to capture in real time a rotated image of the superconducting cable 3 after being rotated by the rotating mechanism 13, and accordingly, the data processing module 23 identifies the rotated image and calculates the rotation angle deviation value and sends the rotation angle deviation value to the control processing module 15.

[0060] The first high-speed camera module 21 captures an image of the superconducting cable 3 after being bent by the bending mechanism 14. The data processing module 23 identifies the image and calculates the bending angle deviation. This allows for accurate and reliable measurement of the bending angle deviation, improving the accuracy of bending angle deviation measurement and control. The second high-speed camera module 22 captures an image of the superconducting cable 3 after being rotated by the rotating mechanism 13. The data processing module 23 identifies the image and calculates the rotation angle deviation. This allows for accurate and reliable measurement of the rotation angle deviation, improving the accuracy of rotation angle deviation measurement and control. Furthermore, the detection assembly 2 has a rational hardware structure and efficient measurement and data processing processes, improving measurement and control efficiency and facilitating the automation and intelligentization of superconducting cable 3 bending.

[0061] Optionally, both the first high-speed camera module 21 and the second high-speed camera module 22 are high-speed industrial cameras.

[0062] In some embodiments, the first high-speed camera module 21 is arranged above the mounting axis of the bending mold 142. In this way, after the superconducting cable 3 is bent, the bending fixture 144 is released, and the first high-speed camera module 21 takes a bent image of the superconducting cable 3 from above in real time. The bent image is a top-view image, in which the image of the superconducting cable 3 is in an arc shape, which is conducive to the data processing module 23 to accurately process the bending image and accurately calculate the bending angle deviation value.

[0063] The second high-speed camera module 22 is arranged on the rotation axis and is opposite to the rotating mechanism 13. In this way, when the superconducting cable 3 rotates, the rotating clamp 133 is released, and the second high-speed camera module 22 takes a rotational image of the superconducting cable 3 after rotation in real time from the direction opposite to the linear feed direction. The rotational image is an end side view, in which the image of the superconducting cable 3 is in the form of a straight line segment. One end point of the straight line segment image represents a straight line segment of the superconducting cable 3. The straight line segment in the straight line segment image represents an arc-shaped segment of the superconducting cable 3. The position of the straight line segment in the straight line segment image represents the rotation angle of the superconducting cable 3. This is conducive to the data processing module 23 accurately processing the rotation image and accurately calculating the rotation angle deviation value.

[0064] In some embodiments, the detection assembly 2 also includes a first bracket 24 and a second bracket 25; the first bracket 24 is fixed on the bending mechanism 14, and the first high-speed camera module 21 is fixed on the first bracket 24; the second bracket 25 is fixed on the bending mechanism 14, and the second high-speed camera module 22 is fixed on the second bracket 25.

[0065] The first bracket 24 is provided to facilitate fixing of the first high-speed camera module 21 ; the second bracket 25 is provided to facilitate fixing of the second high-speed camera module 22 .

[0066] Specifically, the first bracket 24 and the second bracket 25 are both L-shaped.

[0067] In some embodiments, the data processing module 23 includes an image processor 231, a logic calculator 232 and a first communication group 233. The image processor 231 is used to distinguish between bent images and rotated images. Specifically, it identifies the superconducting cable 3 in the bent image and the superconducting cable 3 in the rotated image. The logic calculator 232 is used to calculate the bending angle deviation value based on the recognition image corresponding to the bent image, and to calculate the rotation angle deviation value based on the recognition image corresponding to the rotated image.

[0068] Correspondingly, the control processing module 15 includes a control processor 151 and a second communication group 152. The control processor 151 is used to control the feeding of the straightening mechanism 12, the rotation of the rotating mechanism 13, and the start and stop of the bending mechanism 14; when the bending angle deviation value exceeds the preset bending tolerance value, the control processor 151 controls the bending mechanism 14 to perform bending correction on the superconducting cable 3; when the rotation angle deviation value exceeds the preset rotation tolerance value, the control processor 151 controls the rotating mechanism 13 to perform rotation correction on the superconducting cable 3; the second communication group 152 communicates with the first communication group 233.

[0069] As a result, the data detected by the detection component 2 is accurate and reliable, which improves the accuracy of measurement and control; in addition, the data processing process of the detection component 2 and the control processing module 15 is efficient, which improves the efficiency of measurement and control, and is conducive to realizing the automation and intelligence of the bending of the superconducting cable 3.

[0070] In some embodiments, the image processor 231 uses a visual processor chip; the logic calculator 232 uses an FPGA (field programmable gate array) chip; and the first communication group 233 uses an infrared communication module.

[0071] like Figures 1 to 4 As shown, the second aspect of the present invention further proposes a correction method for a correction device 1000 for superconducting cable bending.

[0072] According to a second embodiment of the present invention, a correction method for a superconducting cable bending correction device 1000 is provided, wherein the superconducting cable bending correction device 1000 is the superconducting cable bending correction device 1000 of the first embodiment of the present invention. The correction method comprises the following steps:

[0073] S1: The superconducting cable 3 is placed on the guide support mechanism 11 and straightened by the straightening mechanism 12. The straightened superconducting cable 3 passes through the rotating mechanism 13. When the section of the superconducting cable 3 to be bent reaches the bending station of the bending mechanism 14, the straightening mechanism 12 stops feeding.

[0074] Among them, the determination of the arrival of the section to be bent of the superconducting cable 3 at the bending station can be determined by the feed length sensor 123 of the straightening mechanism 12 measuring the feed length of the superconducting cable 3 in real time and feeding it back to the control processing module 15, which controls the straightening mechanism 12 to feed and stop feeding.

[0075] S2: The bending mechanism 14 bends the section to be bent.

[0076] Specifically, the control processing module 15 controls the bending fixture 144 to press the superconducting cable 3 against the side surface of the bending mold 142 .

[0077] S3 : After the bending is completed, the bending mechanism 14 releases the superconducting cable 3 to obtain the bent section. The detection component 2 detects the bending angle deviation value of the bent section and sends the bending angle deviation value to the control processing module 15 .

[0078] Specifically, the first high-speed camera module 21 takes a real-time top-down shot of a bent image of the bent section of the superconducting cable 3 and sends it to the data processing module 23. The image recognizer in the data processing module 23 recognizes the superconducting cable 3 in the bent image. The logic calculator 232 in the data processing module 23 counts the bending angle deviation value according to the recognition image corresponding to the bent image, and sends it to the control processing module 15 through the first communication group 233. The second communication group 152 of the control processing module 15 receives it and transmits it to the control processor 151 of the control processing module 15.

[0079] S4: If the bending angle deviation exceeds the preset bending tolerance value, the control processing module 15 controls the bending mechanism 14 to perform bending correction on the bent section. After the bending correction, the bending mechanism 14 releases the superconducting cable 3 .

[0080] S5: After step S4 is completed, the straightening mechanism 12 starts feeding the superconducting cable 3 according to a predetermined length and then stops feeding.

[0081] Among them, the determination of whether the part to be rotated of the superconducting cable 3 reaches the rotation position can be determined by the feed length sensor 123 of the straightening mechanism 12 measuring the feed length of the superconducting cable 3 in real time and feeding it back to the control processing module 15, which controls the straightening mechanism 12 to feed and stop feeding.

[0082] S6: The rotating mechanism 13 clamps the superconducting cable 3 and rotates it.

[0083] Specifically, after the superconducting cable 3 is clamped by the rotating clamp 133 , the superconducting cable 3 is rotated.

[0084] S7 : After the rotation is completed, the rotating mechanism 13 releases the superconducting cable 3 , and the detection component 2 detects the rotation angle deviation value of the superconducting cable 3 and sends the rotation angle deviation value to the control processing module 15 .

[0085] Specifically, the second high-speed camera module 22 captures a rotating image of the superconducting cable 3 from the side of the end in real time and sends it to the data processing module 23. The image recognizer in the data processing module 23 recognizes the superconducting cable 3 in the rotating image. The logic calculator 232 in the data processing module 23 counts the rotation angle deviation value according to the recognized rotating image and sends it to the control processing module 15 through the first communication group 233. The second communication group 152 of the control processing module 15 receives it and transmits it to the control processor 151 of the control processing module 15.

[0086] S8 : If the rotation angle deviation exceeds the preset rotation tolerance value, the control processing module 15 controls the rotation mechanism 13 to perform rotation correction on the superconducting cable 3 . After the rotation correction, the rotation mechanism 13 releases the superconducting cable 3 .

[0087] After step S8 is completed, the superconducting cable 3 is fed again and the above steps are repeated to perform the next bending, thereby achieving multi-dimensional bending of the superconducting cable 3 .

[0088] Since the correction method of the superconducting cable bending correction device 1000 of the second embodiment of the present invention adopts the superconducting cable bending correction device 1000 of the first embodiment of the present invention, the correction method of the superconducting cable bending correction device 1000 of the second embodiment of the present invention has basically the same technical effects as the superconducting cable bending correction device 1000 of the first embodiment of the present invention, and will not be repeated here.

[0089] In some embodiments, in step S4, a bending tolerance of ±10 minutes is preset. The bending mechanism 14 performs bending correction on the bent section by fine-tuning the bending die 142 of the bending mechanism 14 in 5-minute increments, then re-controlling the bending mechanism 14 to bend the bent section until the bending angle deviation is within the preset bending tolerance. This bending correction improves the accuracy and consistency of the superconducting cable 3 fabrication process.

[0090] In some embodiments, in step S8, a rotation tolerance of ±30 minutes is preset. Rotational correction of the superconducting cable 3 by the rotation mechanism 13 is performed by fine-tuning the rotation mechanism 13 in 5-minute increments and then re-controlling the rotation mechanism 13 until the rotation angle deviation falls within the preset rotation tolerance. This rotational correction improves the accuracy and consistency of the superconducting cable 3 fabrication.

[0091] Another object of the present invention is to provide a nuclear fusion device.

[0092] The nuclear fusion device according to the third embodiment of the present invention includes a superconducting cable 3 obtained by the correction method of the superconducting cable bending correction device according to the second embodiment of the present invention.

[0093] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
