Description

Technical Field

[0001] This invention relates to the field of superconducting magnet technology, and in particular to a cooling monitoring method and system for conductive cooling high-temperature superconducting magnets. Background Technology

[0002] Superconducting magnets are electromagnets that use coils made from type II superconductors with high transition temperatures and exceptionally high critical magnetic fields at low temperatures. Their main characteristics are the absence of electrical losses due to wire resistance and magnetic losses due to the presence of an iron core, making them highly practical. The operating temperature of high-temperature superconducting magnets is typically 4.2–50 K, and their cooling method depends on the operating temperature. Common cooling methods for high-temperature superconducting magnets include liquid helium immersion, nitrogen immersion, and conductive cooling. Compared to liquid immersion and nitrogen immersion, conductive cooling offers advantages such as simple structure, easy operation, and safe and controllable quenching.

[0003] However, conventional conductive cooling methods mostly involve directly running a refrigerator to cool the high-temperature superconducting magnet. This method does not consider the actual operating conditions of the high-temperature superconducting magnet, which can easily lead to uneven internal temperature and inaccurate control of the magnet's operating temperature, thus affecting the stability of the stress field and electromagnetic field. Therefore, there is an urgent need for a conductive cooling monitoring method and system for high-temperature superconducting magnets that can precisely control the operating temperature and ensure the uniformity of internal temperature. Summary of the Invention

Example

[0022] High-temperature superconducting magnets typically operate at temperatures between 4.2 and 50 K. Their cooling methods depend on the magnet's operating temperature. Common cooling methods for high-temperature superconducting magnets include liquid helium immersion, nitrogen immersion, and conductive cooling. Compared to liquid and nitrogen immersion, conductive cooling offers advantages such as simple structure, easy operation, and safe and controllable quenching. However, conventional conductive cooling methods often involve directly running a refrigerator to cool the high-temperature superconducting magnet. This method does not consider the actual operating conditions of the magnet, easily leading to uneven internal temperature and making it difficult to accurately control the operating temperature, thus affecting the stability of the stress field and electromagnetic field.

[0023] This invention provides a cooling monitoring method for conductive-cooled high-temperature superconducting magnets, such as... Figure 1 As shown, it includes: S1, acquire the operating data of the conductive cooling high-temperature superconducting magnet, and determine the operating temperature of the conductive cooling high-temperature superconducting magnet based on the operating data.

[0024] S2, acquire parameter data of the conductive cooling high-temperature superconducting magnet, and correct the operating temperature based on the parameter data to obtain the corrected operating temperature of the conductive cooling high-temperature superconducting magnet.

[0025] S3, set the operating parameters of the refrigeration unit according to the corrected operating temperature.

[0026] S4. Obtain the real-time cooling temperature of the conductive-cooled high-temperature superconducting magnet when the refrigerator is working. A target cooling temperature is preset. Determine whether the cooling process meets the standard based on the target cooling temperature and the real-time cooling temperature, and adjust the operating parameters of the refrigerator to achieve cooling monitoring of the conductive-cooled high-temperature superconducting magnet.

[0027] In some embodiments of this application, the operating data includes operating current and operating voltage.

[0028] The parameter data includes the number of coil layers and the coil length of the conductive-cooled high-temperature superconducting magnet.

[0029] In some embodiments of this application, a specific method for determining the operating temperature of a conductively cooled high-temperature superconducting magnet is disclosed. The method for determining the operating temperature of the conductively cooled high-temperature superconducting magnet based on the operating data includes: Determine the product C of the operating current and the operating voltage, and set the operating temperature of the conductive cooling high-temperature superconducting magnet based on the product C.

[0030] A first preset product interval (C1, C2), a second preset product interval (C2, C3), and a third preset product interval (C3, C4) are set.

[0031] A first preset operating temperature T1, a second preset operating temperature T2, and a third preset operating temperature T3 are set, and T1 < T2 < T3.

[0032] When the product C is within the first preset product range (C1, C2), the operating temperature of the conductive-cooled high-temperature superconducting magnet is set to the first preset operating temperature T1; when the product C is within the second preset product range (C2, C3), the operating temperature of the conductive-cooled high-temperature superconducting magnet is set to the second preset operating temperature T2; when the product C is within the third preset product range (C3, C4), the operating temperature of the conductive-cooled high-temperature superconducting magnet is set to the third preset operating temperature T3.

[0033] In this embodiment, a superconducting magnet refers to an electromagnet whose coil is made of a type II superconductor with a high transition temperature and a particularly high critical magnetic field at low temperatures. Its main characteristics are the absence of electrical losses due to wire resistance and the absence of magnetic losses due to the presence of an iron core, making it highly practical. When a superconducting magnet operates, it generates a large amount of heat, which in turn increases the temperature of the high-temperature superconducting magnet. Therefore, this invention determines the operating temperature of the conductive-cooled high-temperature superconducting magnet by determining the product of the operating current and the operating voltage, i.e., the power of the superconducting magnet; the larger the product, the higher the temperature.

[0034] In some embodiments of this application, the operating temperature is corrected based on the parameter data to obtain the corrected operating temperature of the conductive-cooled high-temperature superconducting magnet, including: Determine the ratio of the coil length to the number of coil layers, and select the corresponding correction coefficient based on the ratio.

[0035] The operating temperature is corrected according to the correction factor to obtain the corrected operating temperature of the conductive cooling high-temperature superconducting magnet.

[0036] In some embodiments of this application, a specific method for correcting the operating temperature is disclosed, which sets a first preset ratio interval (B1, B2], a second preset ratio interval (B2, B3], and a third preset ratio interval (B3, B4).

[0037] A first correction coefficient h1, a second correction coefficient h2, and a third correction coefficient h3 are set, and h1 > h2 > h3.

[0038] Based on the ratio B, a corresponding correction coefficient is selected to correct the working temperature, thereby obtaining the corrected working temperature t of the conductive cooling high-temperature superconducting magnet. At this time, the working temperature is the i-th preset working temperature Ti.

[0039] When the ratio B is in the first preset ratio range (B1, B2), a first correction coefficient h1 is selected to correct the operating temperature, resulting in a corrected operating temperature t = Ti * h1 for the conductive-cooled high-temperature superconducting magnet; when the ratio B is in the second preset ratio range (B2, B3), a second correction coefficient h2 is selected to correct the operating temperature, resulting in a corrected operating temperature t = Ti * h2 for the conductive-cooled high-temperature superconducting magnet; when the ratio B is in the third preset ratio range (B3, B4), a third correction coefficient h3 is selected to correct the operating temperature, resulting in a corrected operating temperature t = Ti * h3 for the conductive-cooled high-temperature superconducting magnet.

[0040] In this embodiment, the high-temperature superconducting magnet is an electromagnet with a coil made of a type II superconductor. When the coil length is fixed, the more coil layers there are, the higher the heat accumulated when the high-temperature superconducting magnet is working. That is, the smaller the ratio of the coil length to the number of coil layers, the higher the heat accumulated when the high-temperature superconducting magnet is working. Therefore, when the ratio is larger, the selected correction coefficient is smaller, and the corrected operating temperature of the conductive cooling high-temperature superconducting magnet is lower.

[0041] In some embodiments of this application, a specific method for setting the operating parameters of a refrigeration unit is disclosed, which, based on the modified operating temperature, includes: The cooling power of the refrigerator is set according to the corrected operating temperature t.

[0042] A first preset corrected operating temperature range (A1, A2) is set, a second preset corrected operating temperature range (A2, A3) is set, and a third preset corrected operating temperature range (A3, A4) is set.

[0043] The system is set with a first preset cooling power P1, a second preset cooling power P2, and a third preset cooling power P3, where P1 < P2 < P3.

[0044] When the corrected operating temperature is within the first preset corrected operating temperature range (A1, A2), the cooling power of the refrigerator is set to the first preset cooling power P1; when the corrected operating temperature is within the second preset corrected operating temperature range (A2, A3), the cooling power of the refrigerator is set to the second preset cooling power P2; when the corrected operating temperature is within the third preset corrected operating temperature range (A3, A4), the cooling power of the refrigerator is set to the third preset cooling power P3.

[0045] In this embodiment, the conductive-cooled high-temperature superconducting magnet requires cooling during operation. The higher the corrected operating temperature, the greater the required cooling capacity and the higher the cooling power of the refrigerator. Therefore, by setting several corrected operating temperature ranges and determining the range within which the corrected operating temperature falls, the cooling power of the refrigerator is set.

[0046] In some embodiments of this application, determining whether the cooling process meets the standard based on the target cooling temperature and the real-time cooling temperature includes: Set the acceptable temperature range according to the target cooling temperature.

[0047] If the real-time cooling temperature is within the acceptable temperature range, then the cooling process is determined to meet the standard.

[0048] If the real-time cooling temperature is not within the acceptable temperature range, the cooling process is determined to be non-compliant with the standard.

[0049] In some embodiments of this application, the minimum value of the temperature acceptance range is 90% of the target cooling temperature, and the maximum value of the temperature acceptance range is 110% of the target cooling temperature.

[0050] In this embodiment, the temperature acceptance range is set as (target cooling temperature * 90%, target cooling temperature * 110%), and the upper and lower fluctuation range is set as 10%. When the real-time cooling temperature is higher than 110% of the target cooling temperature, it means that the real-time cooling temperature has not reached the standard, which means that the conductive cooling high-temperature superconducting magnet needs to continue to be cooled.

[0051] In some embodiments of this application, the operating parameters of the refrigeration unit are adjusted, including: Determine the temperature difference between the target cooling temperature and the real-time cooling temperature.

[0052] The operating parameters of the refrigerator are adjusted according to the temperature difference to cool the conductive-cooled high-temperature superconducting magnet.

[0053] This invention also discloses a cooling monitoring system for conductive-cooled high-temperature superconducting magnets using the above-described cooling monitoring method, such as... Figure 2 As shown, it includes: The acquisition module is used to acquire the working data, parameter data, and real-time cooling temperature of the conductive-cooled high-temperature superconducting magnet.

[0054] The processing module is used to determine the operating temperature of the conductive-cooled high-temperature superconducting magnet based on the operating data, and to correct the operating temperature based on the parameter data to obtain the corrected operating temperature of the conductive-cooled high-temperature superconducting magnet.

[0055] The control module is used to set and control the operating parameters of the refrigeration unit according to the corrected operating temperature.

[0056] The judgment module has a preset target cooling temperature. The judgment module is used to determine whether the cooling process meets the standard based on the target cooling temperature and the real-time cooling temperature, and to adjust the working parameters of the refrigerator to realize the cooling monitoring of the conductive cooling high-temperature superconducting magnet.
