Description

TECHNICAL FIELD

[0001] The application relates to the field of wind power generation technology, in particular to a double-mode stator contactor and a copper bar temperature measurement and cooling monitoring device. BACKGROUND

[0002] The existing wind power plant generally adopts a doubly-fed wind turbine generator set to generate power. In the doubly-fed wind turbine generator set, a plurality of stator short-circuit contactors are generally short-circuited by a short-circuit copper bar to form a stator short-circuit current loop. During power generation, when the output power of the doubly-fed wind turbine generator set is large, the current in the stator short-circuit current loop will be relatively large, so the current in the short-circuit copper bar will also be relatively large. Since the current has a thermal effect, it will cause the temperature of the short-circuit copper bar to rise rapidly. When the temperature of the copper bar is too high, it will affect the service life of the copper bar. And the heat emitted by the copper bar will also cause the lines in the doubly-fed wind turbine generator set to age, thereby affecting the safe operation of the doubly-fed wind turbine generator set.

[0003] In order to solve the above problems, an infrared temperature measurement sensor is arranged in the doubly-fed wind turbine generator set to detect the real-time temperature of the short-circuit copper bar, thereby facilitating heat dissipation of the short-circuit copper bar when the real-time temperature of the short-circuit copper bar is high.

[0004] However, the real-time temperature of the short-circuit copper bar detected by the above-mentioned infrared temperature measurement sensor is not accurate, thereby affecting the normal operation of the doubly-fed wind turbine generator set. CONTENT OF THE INVENTION

[0005] The application provides a double-mode stator contactor and a copper bar temperature measurement and cooling monitoring device, which is provided with a temperature measurement structure and a temperature detection assembly in contact with the temperature measurement structure. This can more accurately detect the real-time temperature of the temperature measurement structure, thereby facilitating control of the real-time temperature of the temperature measurement structure, thereby facilitating the normal operation of the device. In addition, the device is provided with a heat dissipation device and a control assembly, thereby being able to dissipate heat from the temperature measurement structure in a timely manner according to the detected real-time temperature, thereby realizing the function of automatically dissipating heat from the temperature measurement structure.

[0006] In order to achieve the above-mentioned purpose, the application adopts the following technical solutions:

[0007] The application provides a dual-mode stator contactor and copper bar temperature measurement and cooling monitoring device, which comprises a structure to be measured, a temperature detection assembly, a heat dissipation device and a control assembly. The temperature detection assembly is in contact with the structure to be measured and is used to detect the real-time temperature of the structure to be measured. The heat dissipation device is used to dissipate heat for the structure to be measured. The heat dissipation device and the temperature detection assembly are both electrically connected with the control assembly, and the control assembly is used to acquire the real-time temperature and send a working instruction to the heat dissipation device.

[0008] As an optional implementation, the dual-mode stator contactor and copper bar temperature measurement and cooling monitoring device further comprises at least two stator short-circuit contactors arranged at intervals.

[0009] The structure to be measured is a metal conductive structure, and the at least two stator short-circuit contactors are both connected with the metal conductive structure.

[0010] As an optional implementation, each stator short-circuit contactor has a metal connecting piece, and all the metal connecting pieces are connected with the metal conductive structure.

[0011] As an optional implementation, the metal connecting piece is a metal connecting plate, the metal connecting plate has oppositely arranged first and second connecting plate surfaces, and the metal conductive structure comprises oppositely arranged first and second short-circuit copper plates.

[0012] All the first connecting plate surfaces are located in the same plane and are connected with the first short-circuit copper plate, and all the second connecting plate surfaces are located in the same plane and are connected with the second short-circuit copper plate.

[0013] As an optional implementation, the temperature detection assembly comprises a resistance temperature sensor, the resistance temperature sensor is fixedly connected to the surface of the structure to be measured and is used to detect the real-time temperature of the structure to be measured.

[0014] As an optional implementation, the temperature detection assembly further comprises a connecting bolt, the connecting bolt is arranged through the resistance temperature sensor and the structure to be measured, so that the resistance temperature sensor and the structure to be measured are fixedly connected.

[0015] As an optional implementation, the heat dissipation device comprises a heat dissipation fan, and the heat dissipation fan is electrically connected with the control assembly.

[0016] When the duration of the real-time temperature being greater than the first preset temperature is greater than the first preset time period, the control component sends a starting operation instruction to the heat dissipation fan; when the duration of the real-time temperature being less than the second preset temperature is greater than the second preset time period, the control component sends a closing operation instruction to the heat dissipation fan.

[0017] As an optional implementation, the air outlet of the heat dissipation fan is directed towards the temperature-measured structure; and the center of the temperature-measured structure is oppositely arranged to the center of the air outlet along the air outlet direction of the air outlet.

[0018] As an optional implementation, the heat dissipation device further comprises a liquid cooling heat dissipation component, which comprises a heat dissipation pipeline, the heat dissipation pipeline is wound around the temperature-measured structure, and the heat dissipation pipeline is filled with cooling medium, and the liquid cooling heat dissipation component is electrically connected with the control component.

[0019] When the duration of the real-time temperature being greater than the first preset temperature is greater than the first preset time period, the control component sends a starting operation instruction to the liquid cooling heat dissipation component to start the flow of the cooling medium in the heat dissipation pipeline; and when the duration of the real-time temperature being less than the second preset temperature is greater than the second preset time period, the control component sends a closing operation instruction to the liquid cooling heat dissipation component to stop the flow of the cooling medium in the heat dissipation pipeline.

[0020] As an optional implementation, the liquid cooling heat dissipation component further comprises a liquid container and a circulating pump, the liquid container is used for containing cooling medium, and the inlet end and the outlet end of the heat dissipation pipeline are in communication with the liquid container.

[0021] The circulating pump is connected to the inlet end of the heat dissipation pipeline, and is used for providing circulating power to make the cooling medium in the heat dissipation pipeline flow in a circulating manner.

[0022] Compared with the prior art, the application has at least the following beneficial effects:

[0023] Since the dual-mode stator contactor and copper bar temperature measurement and cooling monitoring device comprises a temperature-measured structure, a temperature detection component, a heat dissipation device and a control component. The temperature detection component is in contact with the temperature-measured structure, and is used for detecting the real-time temperature of the temperature-measured structure. Compared with the related art which detects the real-time temperature by using an infrared temperature measurement sensor, the real-time temperature of the temperature-measured structure can be more accurately detected, and the real-time temperature of the temperature-measured structure is controlled, thereby facilitating the normal operation of the dual-mode stator contactor and copper bar temperature measurement and cooling monitoring device.

[0024] The heat dissipation device is used to dissipate heat from the structure being measured. Thus, when the temperature of the structure being measured is high, the heat dissipation device can dissipate heat, thereby preventing the temperature of the structure from becoming too high.

[0025] Since both the heat dissipation device and the temperature detection component are electrically connected to the control component, the control component acquires the real-time temperature and sends operating commands to the heat dissipation device. This allows the control component to obtain the real-time temperature of the structure under test and then issue an on / off command to the heat dissipation device based on the magnitude of the real-time temperature. Specifically, when the detected real-time temperature is high and persists for a long period, the control component can analyze that the structure under test has a high-temperature risk. The control component then issues an on command to the heat dissipation device, which then dissipates heat to the structure under test, thereby eliminating the high-temperature risk. When the detected real-time temperature is low and persists for a long period, the control component can analyze that the high-temperature risk of the structure under test has been eliminated. The control component then issues a off command to the heat dissipation device, which then shuts down, thus preventing the heat dissipation device from wasting energy and achieving energy conservation. This realizes the function of automatically dissipating heat from the structure under test and achieves the goal of energy saving and environmental protection. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] In doubly-fed induction generator (DFIG) wind turbines, multiple stator shorting contactors are typically shorted using shorting copper busbars to form a stator shorting current loop. During power generation, when the output power of the DFIG wind turbine is high, the current in the stator shorting current loop is also high, resulting in a high current in the shorting copper busbar. Due to the thermal effect of current, the temperature of the shorting copper busbar rises rapidly. Excessive temperature of the copper busbar can affect its lifespan. Furthermore, the heat dissipated by the copper busbar can cause aging of the wiring within the DFIG wind turbine, thus affecting its safe operation. To address these issues, related technologies incorporate infrared temperature sensors within the DFIG wind turbine to monitor the real-time temperature of the shorting copper busbar, facilitating heat dissipation when the real-time temperature is high.

[0035] However, the real-time temperature detected by the infrared temperature sensor is not accurate enough, which is detrimental to the normal operation of the doubly fed wind turbine generator.

[0036] To address the aforementioned technical problems, the dual-mode stator contactor and copper busbar temperature monitoring device provided by this utility model solves these problems by incorporating a temperature detection component that contacts the structure to be measured. Specifically, the device includes the structure to be measured, a temperature detection component, a heat dissipation device, and a control component. The temperature detection component contacts the structure to be measured and is used to detect the real-time temperature of the structure. Compared to the method of detecting real-time temperature using an infrared temperature sensor in related technologies, this method can more accurately detect the real-time temperature of the structure to be measured, thereby facilitating the control of the real-time temperature of the structure and promoting the normal operation of the device.

[0037] The heat dissipation device is used to dissipate heat from the structure being measured. Thus, when the temperature of the structure being measured is high, the heat dissipation device can dissipate heat, thereby preventing the temperature of the structure from becoming too high.

[0038] Since both the heat dissipation device and the temperature detection component are electrically connected to the control component, the control component acquires the real-time temperature and sends operating commands to the heat dissipation device. This allows the control component to obtain the real-time temperature of the structure under test and then issue an on / off command to the heat dissipation device based on the magnitude of the real-time temperature. Specifically, when the detected real-time temperature is high and persists for a long period, the control component can analyze that the structure under test has a high-temperature risk. The control component then issues an on command to the heat dissipation device, which then dissipates heat to the structure under test, thereby eliminating the high-temperature risk. When the detected real-time temperature is low and persists for a long period, the control component can analyze that the high-temperature risk of the structure under test has been eliminated. The control component then issues a off command to the heat dissipation device, which then shuts down, thus preventing the heat dissipation device from wasting energy and achieving energy conservation. This realizes the function of automatically dissipating heat from the structure under test and achieves the goal of energy saving and environmental protection.

[0039] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0040] The following provides a detailed description of the specific structure and various possible implementation methods of the aforementioned dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device.

[0041] Figure 1 This is a schematic diagram of a portion of the structure of a dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100 provided in an embodiment of this application. Figure 2 This is a top view of a partial structure of a dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100 provided in an embodiment of this application. Figure 3This is a cross-sectional view of a portion of the structure of a dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100 provided in an embodiment of this application, formed by cutting a plane perpendicular to the first connecting plate surface 1511. Figure 4 This is a schematic diagram showing the connection relationship of a part of the structure of a dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100 provided in an embodiment of this application.

[0042] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The dual-mode stator contactor and copper busbar temperature monitoring device 100 includes a temperature-measuring structure 110, a temperature detection component 120, a heat dissipation device 130, and a control component 140. The temperature detection component 120 is in contact with the temperature-measuring structure 110 and is used to detect the real-time temperature of the structure 110. The heat dissipation device 130 is used to dissipate heat from the temperature-measuring structure 110. Both the heat dissipation device 130 and the temperature detection component 120 are electrically connected to the control component 140, which is used to acquire the real-time temperature and issue operating commands to the heat dissipation device 130.

[0043] In this embodiment, the dual-mode stator contactor and copper busbar temperature monitoring device 100 includes a temperature-measuring structure 110, a temperature detection component 120, a heat dissipation device 130, and a control component 140. The temperature detection component 120 is in contact with the temperature-measuring structure 110 and is used to detect the real-time temperature of the structure 110. Compared to the method of detecting real-time temperature using an infrared temperature sensor in related technologies, this method can more accurately detect the real-time temperature of the temperature-measuring structure 110, thereby facilitating the control of the real-time temperature of the structure 110 and promoting the normal operation of the dual-mode stator contactor and copper busbar temperature monitoring device 100.

[0044] Since the heat dissipation device 130 is used to dissipate heat from the structure 110 to be measured, when the temperature of the structure 110 to be measured is high, the heat dissipation device can dissipate heat from the structure 110 to be measured, thereby preventing the temperature of the structure 110 to be too high.

[0045] Since both the heat dissipation device 130 and the temperature detection component 120 are electrically connected to the control component 140, the control component 140 acquires the real-time temperature and sends operating commands to the heat dissipation device 130. In this way, the control component 140 can acquire the real-time temperature of the structure 110 under test and then issue an on / off operating command to the heat dissipation device 130 based on the magnitude of the real-time temperature. Specifically, when the detected real-time temperature is high and lasts for a long time, the control component 140 can analyze that the structure 110 under test has a high temperature risk. Then, the control component 140 will issue an on operating command to the heat dissipation device 130, which will then dissipate heat to the structure 110 under test, thereby eliminating the high temperature risk. When the detected real-time temperature is low and lasts for a long time, the control component 140 can analyze that the high temperature risk of the structure 110 under test has been eliminated. Then, the control component 140 will issue a off operating command to the heat dissipation device 130, which will then shut down, thus preventing the heat dissipation device 130 from wasting energy and achieving energy saving. This achieves the function of automatically dissipating heat from the structure 110 under temperature measurement, and also achieves the goal of energy saving and environmental protection.

[0046] It should be noted that the real-time temperature mentioned above refers to the temperature at which the temperature detection component 120 detects the temperature of the structure 110 to be measured.

[0047] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100 also includes at least two stator short-circuit contactors 150 spaced apart. The structure to be measured 110 is a metal conductive structure, and at least two stator short-circuit contactors 150 are connected to the metal conductive structure.

[0048] In this embodiment, since the temperature-measuring structure 110 is a metal conductive structure, at least two stator short-circuiting contactors 150 are connected to the metal conductive structure. In this way, the temperature-measuring structure 110 can short-circuit at least two spaced stator short-circuiting contactors 150 to form a stator short-circuiting current loop, thereby fulfilling the basic functions of the dual-mode stator contactor and the copper busbar temperature measurement and cooling monitoring device 100.

[0049] It should be noted that the number of stator short-circuit contactors 150 mentioned above can be three or two, or other numbers, and this application embodiment does not limit this.

[0050] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 andFigure 4 Each stator shorting contactor 150 has a metal connector 151, and all metal connectors 151 are connected to a metal conductive structure.

[0051] In this embodiment, each stator shorting contactor 150 has a metal connector 151, which facilitates the conductive connection between the metal conductive structure and all stator shorting contactors 150 and improves the reliability of the connection between the metal conductive structure and the stator shorting contactors 150.

[0052] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The metal connector 151 is a metal connecting plate, which has a first connecting plate surface 1511 and a second connecting plate surface 1512 disposed opposite to each other. The metal conductive structure includes a first shorting copper plate 111 and a second shorting copper plate 112 disposed opposite to each other. All the first connecting plate surfaces 1511 are located on the same plane and are all connected to the first shorting copper plate 111, and all the second connecting plate surfaces 1512 are located on the same plane and are all connected to the second shorting copper plate 112.

[0053] In this embodiment, since the metal connector 151 is a metal connecting plate, the metal connecting plate has a first connecting plate surface 1511 and a second connecting plate surface 1512 that are disposed opposite to each other. Both the first connecting plate surface 1511 and the second connecting plate surface 1512 are used to connect with the metal conductive structure. This helps to increase the connection area between the metal connector 151 and the metal conductive structure, thereby further improving the reliability of the connection between the metal conductive structure and the stator short-circuit contactor 150.

[0054] The metal conductive structure includes a first shorting copper plate 111 and a second shorting copper plate 112 arranged opposite to each other. All the first connecting plate surfaces 1511 are located on the same plane and are connected to the first shorting copper plate 111, and all the second connecting plate surfaces 1512 are located on the same plane and are connected to the second shorting copper plate 112. Thus, the metal conductive structure includes two copper plates. Compared to using a single copper plate, this increases the connection area between the metal connector 151 and the metal conductive structure, thereby further improving the reliability of the connection between the metal conductive structure and the stator shorting contactor 150. Furthermore, compared to using a single copper plate, this also increases the heat dissipation area of ​​the metal conductive structure, thus improving heat dissipation. Additionally, since copper is a metal with low resistivity, this reduces the resistance of the metal conductive structure, thereby reducing the heat generated by the structure and slowing down the rate of temperature rise.

[0055] It should be noted that the aforementioned metal connecting plate can be an aluminum plate or a copper plate, or a metal plate of other materials; this application embodiment does not limit this.

[0056] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The temperature detection component 120 includes a resistance temperature sensor 121, which is fixedly connected to the surface of the structure to be measured 110 and is used to detect the real-time temperature of the structure to be measured 110.

[0057] Since there is a certain linear relationship between the resistance value of the resistance temperature sensor 121 and its own temperature value, the real-time temperature of the structure to be measured 110 can be accurately detected based on its resistance value, which can further improve the accuracy of the real-time temperature.

[0058] Furthermore, since the resistance temperature sensor 121 is a commonly used temperature monitoring element, its technology is mature, its stability is good, and its cost is low. This is conducive to improving the stability of the dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100, and also conducive to reducing the production cost of the dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100.

[0059] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The temperature detection assembly 120 also includes a connecting bolt 122, which passes through the resistance temperature sensor 121 and the temperature-to-be-measured structure 110 to fix the resistance temperature sensor 121 and the temperature-to-be-measured structure 110 together.

[0060] In this way, the temperature detection component 120 and the temperature-measuring structure 110 are fixedly connected by bolts. Compared with other fixed connection methods, bolt connection is not only more reliable, but also facilitates the replacement of temperature detection component 120 when maintaining the dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100.

[0061] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4The heat dissipation device 130 includes a cooling fan 131, which is electrically connected to the control component 140. When the real-time temperature is higher than the first preset temperature for a duration longer than the first preset time period, the control component 140 sends a start command to the cooling fan 131; when the real-time temperature is lower than the second preset temperature for a duration longer than the second preset time period, the control component 140 sends a shut-off command to the cooling fan 131.

[0062] Since the cooling fan 131 is a commonly used heat dissipation structure, it has good heat dissipation effect, stable performance and low cost, which helps to improve the heat dissipation effect of the heat dissipation device 130 on the temperature measurement structure 110. At the same time, it can improve the stability of the heat dissipation device 130 and reduce the production cost of the heat dissipation device 130.

[0063] Because the cooling fan 131 is electrically connected to the control component 140, when the real-time temperature exceeds the first preset temperature for a duration longer than the first preset time period, the control component 140 can analyze that the structure 110 under temperature measurement has a high-temperature risk. The control component 140 then sends a start command to the cooling fan 131, which then dissipates heat from the structure 110, thus eliminating the high-temperature risk. When the real-time temperature is below the second preset temperature for a duration longer than the second preset time period, the control component 140 can analyze that the high-temperature risk of the structure 110 under temperature measurement has been eliminated. The control component 140 then sends a shut-off command to the cooling fan 131, which then shuts off, thus preventing the cooling fan 131 from wasting energy and achieving energy saving. This realizes the function of automatically dissipating heat from the structure 110 under temperature measurement and achieves the goal of energy saving and environmental protection.

[0064] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The air outlet 1311 of the cooling fan 131 faces the temperature measurement structure 110. The center of the temperature measurement structure 110 and the center of the air outlet 1311 are positioned opposite each other along the air outlet 1311's airflow direction.

[0065] In this embodiment, since the air outlet 1311 of the cooling fan 131 faces the structure 110 to be measured, the air blown out by the cooling fan 131 can easily carry away the heat from the structure 110, thereby improving the heat dissipation effect of the cooling fan 131. Because the center of the structure 110 to be measured and the center of the air outlet 1311 are positioned opposite each other along the air outlet direction, the air blown out by the cooling fan 131 can carry away the heat from the structure 110 to the greatest extent possible, further improving the heat dissipation effect of the cooling fan 131.

[0066] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The heat dissipation device 130 also includes a liquid cooling heat dissipation component 132, which includes a heat dissipation pipe 1321. The heat dissipation pipe 1321 is wound around the temperature-measuring structure 110 and filled with a cooling medium. The liquid cooling heat dissipation component 132 is electrically connected to the control component 140. When the real-time temperature is higher than the first preset temperature for a duration longer than the first preset time period, the control component 140 sends a start-up command to the liquid cooling heat dissipation component 132 to start the flow of the cooling medium in the heat dissipation pipe 1321. When the real-time temperature is lower than the second preset temperature for a duration longer than the second preset time period, the control component 140 sends a shut-off command to the liquid cooling heat dissipation component 132 to stop the flow of the cooling medium in the heat dissipation pipe 1321.

[0067] To further enhance the heat dissipation capacity of the heat dissipation device 130, the heat dissipation device 130 also includes a liquid cooling heat dissipation component 132. The liquid cooling heat dissipation component 132 includes a heat dissipation pipe 1321, which is wound around the temperature-measuring structure 110 and filled with a cooling medium. The liquid cooling heat dissipation component 132 is electrically connected to the control component 140. When the real-time temperature is higher than the first preset temperature for a duration longer than the first preset time period, the control component 140 can analyze that the temperature-measuring structure 110 has a high temperature risk. Then, the control component 140 sends a start-up command to the liquid cooling heat dissipation component 132 to start the flow of the cooling medium in the heat dissipation pipe 1321. When the cooling medium flows, it can absorb the heat of the temperature-measuring structure 110 through heat transfer, thereby eliminating the high temperature risk. When the duration for which the real-time temperature remains below the second preset temperature exceeds the second preset time period, the control component 140 can determine that the high-temperature risk of the temperature-measuring structure 110 has been eliminated. The control component 140 then sends a shutdown command to the liquid cooling heat dissipation component 132 to stop the flow of cooling medium in the heat dissipation pipe 1321. This prevents the liquid cooling heat dissipation component 132 from wasting electrical energy, thus achieving energy saving. This realizes the function of automatically dissipating heat from the temperature-measuring structure 110 and achieves the goal of energy conservation and environmental protection.

[0068] It should be noted that the cooling fan 131 and the liquid cooling heat dissipation component 132 start up and shut down simultaneously during operation.

[0069] It should also be noted that the first and second preset temperatures mentioned above are preset in advance according to actual needs, and the first preset temperature is greater than the second preset temperature.

[0070] It should also be noted that the first preset time period can be 180 seconds, and the second preset time period can be 300 seconds. The lengths of the first and second preset time periods can also be other values, and this application embodiment does not limit this.

[0071] As an optional implementation, in some embodiments, see [link to relevant documentation].

The liquid container 1322 is used to contain the cooling medium, and the inlet and outlet ends of the heat dissipation pipe 1321 are both connected to the liquid container 1322. The circulation pump 1323 is connected to the inlet end of the heat dissipation pipe 1321 and is used to provide circulation power to circulate the cooling medium in the heat dissipation pipe 1321.

[0072] In this embodiment, the liquid cooling heat dissipation component 132 includes a liquid container 1322, which is used to contain the cooling medium. The inlet and outlet ends of the heat dissipation pipe 1321 are both connected to the liquid container 1322. In this way, the liquid container 1322 can continuously provide cooling medium to the heat dissipation pipe 1321, ensuring that the heat dissipation pipe 1321 can continuously absorb the heat of the temperature-measuring structure 110, thereby enabling continuous heat dissipation from the temperature-measuring structure 110.

[0073] Since the liquid cooling heat dissipation assembly 132 also includes a circulation pump 1323, which is connected to the inlet end of the heat dissipation pipe 1321, it is used to provide circulation power to circulate the cooling medium in the heat dissipation pipe 1321. Specifically, the circulation pump 1323 is electrically connected to the control assembly 140, so that the control assembly 140 can control the opening or closing of the circulation pump 1323, thereby controlling the opening or closing of the liquid cooling assembly, thus realizing the function of automatically dissipating heat to the structure 110 under temperature measurement.

[0074] It should be noted that the liquid container 1322 mentioned above can be a container tank or a container bottle, or it can be other types of liquid container 1322. This application embodiment does not limit this.

[0075] It should be noted that the above-mentioned dual-mode stator contactor and copper busbar temperature measurement and cooling monitoring device 100 also includes a chassis 160, on which the stator shorting contactor 150 and the cooling fan 131 are both connected.

[0076] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0077] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0078] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something,” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “above something” or “on top of something,” but also “on something” or “on top of something” without an intermediate feature or layer therebetween, i.e., directly on something.

[0079] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations rotated 90° or be in other orientations, and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
