Description

Technical Field

[0001] This invention relates to the field of control technology for special equipment and devices, and in particular to a heat leakage regulation and treatment system for a conductive cooling high-temperature superconducting magnet. Background Technology

[0002] High-temperature superconducting magnets are important devices used to generate high-intensity magnetic fields and are widely used in fields such as medical imaging, nuclear magnetic resonance, and particle accelerators. However, high-temperature superconducting magnets often face the problem of heat leakage during operation. Heat leakage can cause the magnet temperature to rise, the superconducting performance to decline, and even cause the magnet to lose superconductivity, affecting the performance and stability of the magnet.

[0003] Because the accuracy of heat leakage regulation in traditional high-temperature superconducting magnets is low, it is impossible to accurately treat the heat leakage of high-temperature superconducting magnets. This leads to problems such as low heat exchange efficiency, excessively long heat leakage treatment time, and insufficient utilization of cooling capacity, which is not conducive to the normal operation of high-temperature superconducting magnets. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a heat leakage regulation system for conductive-cooled high-temperature superconducting magnets, comprising: A vacuum container is used to place the high-temperature superconducting magnet and to isolate the high-temperature superconducting magnet from direct contact with the external environment; A cooling circulation unit is used to cool and regulate the heat leakage of the high-temperature superconducting magnet. A temperature monitoring sensor is installed on the cooling cycle unit, and the temperature monitoring sensor is used to monitor the temperature of the circulating refrigerant in the cooling cycle unit in real time. The control unit is connected to the cooling cycle unit and the temperature monitoring sensor respectively. The control unit is used to control the operating conditions of the cooling cycle unit according to the temperature of the circulating refrigerant.

[0005] Furthermore, the temperature monitoring sensor includes: A first sensor is disposed at the inlet of the vacuum container, and the first sensor is used to monitor the first temperature of the refrigerant flowing into the vacuum container; A second sensor is disposed at the outlet of the vacuum container, and the second sensor is used to monitor the second temperature of the refrigerant flowing out of the vacuum container; The first sensor and the second sensor are electrically connected to the control unit, respectively.

[0006] Furthermore, the control unit includes: The data acquisition module is used to acquire the first temperature data and the second temperature data; A processing module is connected to the acquisition module. The processing module is used to determine whether the high-temperature superconducting magnet has heat leakage based on the first temperature data and the second temperature data, and to set the working instructions of the cooling cycle unit after the high-temperature superconducting magnet has heat leakage. A control module is connected to the processing module, and the control module is used to control the cooling circulation unit to perform cooling adjustment processing according to the working instructions.

[0007] Furthermore, the processing module is used to acquire the first temperature data and the second temperature data, and sort the first temperature data and the second temperature data according to the acquisition time order; Calculate the difference between the first temperature in the first temperature data and the second temperature in the second temperature data in the order of collection time. The average of these differences is calculated to obtain the average temperature difference ΔG. The relationship between the average temperature difference and a preset threshold is then determined. If the average temperature difference exceeds the preset threshold, it is determined that the high-temperature superconducting magnet is leaking heat, and the heat leakage of the high-temperature superconducting magnet needs to be adjusted. If the average temperature difference does not exceed the preset threshold, it is determined that the high-temperature superconducting magnet is not leaking heat, and the heat leakage of the high-temperature superconducting magnet does not need to be adjusted.

[0010] Furthermore, the processing module is used to generate a second temperature difference curve from the second temperature difference dataset, and to extract the peak and trough values ​​from the second temperature difference curve. Determine the descending curve segment corresponding to each peak value to the trough value and the ascending curve segment corresponding to each trough value to the peak value, and calculate the descending slope of each descending curve segment and the ascending slope of each ascending curve segment respectively. A standard slope is preset, and the difference between each descending slope and each ascending slope and the standard slope is calculated. The corresponding curve segment is evaluated based on the difference to obtain the evaluation value of each curve segment. Obtain the time length of each curve segment and calculate the ratio of the time length of each curve segment to the time length of the second temperature difference curve. Use this ratio as the weight of each curve segment. The cooling performance evaluation value of the cooling cycle unit is calculated based on the evaluation value of each curve segment. The calculation formula for the cooling performance evaluation value of the cooling cycle unit is as follows: ; Where S is the cooling performance evaluation value of the cooling cycle unit, ai is the weight of the i-th curve segment, and Li is the evaluation value of the i-th curve segment.

[0018] like Figure 1 As shown in the embodiments of this application, a heat leakage regulation system for a conductive-cooled high-temperature superconducting magnet is provided, comprising: a vacuum container for placing the high-temperature superconducting magnet and isolating the high-temperature superconducting magnet from direct contact with the external environment; a cooling circulation unit for cooling and regulating the heat leakage of the high-temperature superconducting magnet; a temperature monitoring sensor disposed on the cooling circulation unit for real-time monitoring of the temperature of the circulating refrigerant in the cooling circulation unit; and a control unit connected to the cooling circulation unit and the temperature monitoring sensor, wherein the control unit controls the operating conditions of the cooling circulation unit according to the temperature of the circulating refrigerant.

[0019] Furthermore, this invention monitors heat leakage from the high-temperature superconducting magnet in real time. Upon heat leakage, a cooling circulation unit rapidly cools and regulates the leakage. The control unit precisely controls the operation of the cooling circulation unit based on the temperature change of the circulating refrigerant. This ensures full utilization of cooling capacity, reduces heat leakage treatment time, improves heat exchange efficiency, and guarantees the normal operation of the high-temperature superconducting magnet.

[0020] like Figure 2 As shown in the embodiments of this application, a heat leakage regulation system for a conductive-cooled high-temperature superconducting magnet is provided. The temperature monitoring sensor includes: a first sensor disposed at the inlet of the vacuum container, which is used to monitor a first temperature of the refrigerant flowing into the vacuum container; and a second sensor disposed at the outlet of the vacuum container, which is used to monitor a second temperature of the refrigerant flowing out of the vacuum container. The first sensor and the second sensor are electrically connected to the control unit, respectively.

[0021] Specifically, the first sensor is located at the inlet of the vacuum container to monitor the temperature of the refrigerant before it flows into the vacuum container, and the second sensor is located at the outlet of the vacuum container to monitor the temperature of the refrigerant after it flows out of the vacuum container. The change in the two temperatures can reflect whether the high-temperature superconducting magnet inside the vacuum container is leaking heat.

[0023] In an embodiment of this application, a heat leakage regulation system for a conductive-cooled high-temperature superconducting magnet is provided. The processing module is used to acquire first temperature data and second temperature data, and sort the first temperature data and second temperature data according to the acquisition time order; calculate the difference between the first temperature in the first temperature data and the second temperature in the second temperature data according to the acquisition time order; calculate the average value of these differences to obtain the average temperature difference ΔG, and determine the relationship between the average temperature difference and a preset threshold. If the average temperature difference exceeds the preset threshold, it is determined that the high-temperature superconducting magnet has heat leakage, and heat leakage regulation processing of the high-temperature superconducting magnet is required. If the average temperature difference does not exceed the preset threshold, it is determined that the high-temperature superconducting magnet has no heat leakage, and heat leakage regulation processing of the high-temperature superconducting magnet is not required.

[0024] In the embodiments of this application, a heat leakage regulation and treatment system for a conductive cooling high-temperature superconducting magnet is provided. The processing module is used to obtain the average temperature difference ΔG, and the control module is used to control the cooling circulation unit.

When △G≤G1, the first preset working condition matrix A1 is selected as the working condition of the cooling cycle unit; When G1 < △G ≤ G2, the second preset working condition matrix A2 is selected as the working condition of the cooling cycle unit; When G2<△G≤G3, the third preset working condition matrix A3 is selected as the working condition of the cooling cycle unit; When G3<△G≤G4, the fourth preset working condition matrix A4 is selected as the working condition of the cooling cycle unit.

[0025] Specifically, the processing module selects a preset working condition matrix as the working condition of the cooling cycle unit based on the obtained temperature difference value and the i-th preset temperature difference value. When the temperature difference value increases, it indicates that the heat leakage of the high-temperature superconducting magnet is becoming more and more serious, and it is necessary to speed up the refrigerant circulation flow rate and increase the refrigerant replenishment amount. Conversely, it is necessary to slow down the refrigerant circulation flow rate and reduce the refrigerant replenishment amount in order to perform precise cooling and adjustment treatment on the heat leakage of the high-temperature superconducting magnet.

The processing module is used to generate a second temperature difference curve from a second temperature difference dataset, and extract the peak and trough values ​​from the second temperature difference curve; determine the descending curve segment corresponding to each peak to trough value and the ascending curve segment corresponding to each trough to peak value, and calculate the descending slope of each descending curve segment and the ascending slope of each ascending curve segment; pre-set a standard slope, calculate the difference between each descending slope and each ascending slope and the standard slope, and evaluate the corresponding curve segment based on the difference to obtain an evaluation value for each curve segment; obtain the time length of each curve segment, and calculate the ratio of the time length of each curve segment to the time length of the second temperature difference curve, using this ratio as the weight of each curve segment; calculate the cooling performance evaluation value of the cooling cycle unit based on the evaluation value of each curve segment, wherein the calculation formula for the cooling performance evaluation value of the cooling cycle unit is: ; Where S is the cooling performance evaluation value of the cooling cycle unit, ai is the weight of the i-th curve segment, and Li is the evaluation value of the i-th curve segment.

[0028] In embodiments of this application, a heat leakage regulation system for a conductive-cooled high-temperature superconducting magnet is provided. The processing module is used to set a first preset cooling performance evaluation value range, a second preset cooling performance evaluation value range, a third preset cooling performance evaluation value range, and a fourth preset cooling performance evaluation value range. The processing module is also used to set a first preset adjustment coefficient m1, a second preset adjustment coefficient m2, a third preset adjustment coefficient m3, and a fourth preset adjustment coefficient m4, where 1 < m1 < m2 < m3 < m4 < 1.5. Based on the i-th preset cooling performance evaluation value range in which the cooling performance evaluation value falls, the i-th preset adjustment coefficient is selected to adjust the working condition matrix Ai of the cooling cycle unit. When the cooling performance evaluation value falls within the first preset cooling performance evaluation value range... When the value is within the first preset cooling performance evaluation value range, the first preset adjustment coefficient m1 is selected to adjust Ai, resulting in Ai(ai*m1, bi*m1); when the cooling performance evaluation value is within the first preset cooling performance evaluation value range, the second preset adjustment coefficient m2 is selected to adjust Ai, resulting in Ai(ai*m2, bi*m2); when the cooling performance evaluation value is within the first preset cooling performance evaluation value range, the third preset adjustment coefficient m3 is selected to adjust Ai, resulting in Ai(ai*m3, bi*m3); when the cooling performance evaluation value is within the first preset cooling performance evaluation value range, the fourth preset adjustment coefficient m4 is selected to adjust Ai, resulting in Ai(ai*m4, bi*m4).

[0029] Specifically, based on the i-th preset cooling performance evaluation value range in which the cooling performance evaluation value is located, the i-th preset adjustment coefficient is selected to adjust the working condition matrix Ai of the cooling cycle unit. The smaller the cooling performance evaluation value, the larger the error of the working condition matrix of the cooling cycle unit, and the more significant the adjustment of the working condition matrix of the cooling cycle unit is required. Conversely, a significant adjustment is made until the heat leakage of the conductive cooling high-temperature superconducting magnet is completely eliminated.
