[0048] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] As a core device in the power system, the operating state of a transformer is directly related to the stability of the power grid and the power supply reliability. During the operation of the transformer, temperature is one of the key factors affecting its performance and lifespan. Excessive temperature will not only accelerate the aging of insulating materials, reduce the service life of the transformer, but also may cause serious faults such as local overheating and insulation breakdown, and even lead to the burning of the transformer, resulting in significant economic losses and safety hazards. Therefore, real - time and accurate monitoring of the internal and external temperatures of the transformer is of great significance for ensuring the safe operation of the power system.

[0050] Traditional temperature monitoring methods (such as thermal resistors, infrared temperature measurement, etc.) often have problems such as insufficient measurement accuracy, limited coverage, and susceptibility to environmental interference, making it difficult to comprehensively reflect the temperature distribution and thermal state of transformers. Especially in large power transformers, the internal temperature distribution is complex, and the temperature changes in hot spots may not be captured in a timely manner by traditional methods, increasing the operation risk. Therefore, developing a multi-source temperature measurement system that can simultaneously monitor the internal and external temperature distributions of transformers and provide comprehensive and accurate temperature data has become an important research direction in the field of transformer temperature monitoring.

[0051] The transformer temperature measurement method provided by the embodiments of this application can be applied to an application environment as Figure 1 shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed in the cloud or other network servers. By detecting the temperature of at least one temperature measurement area in the transformer, the measured temperature of each temperature measurement area in the target period is obtained. Furthermore, according to the temperature correlation relationship between the temperature measurement areas and the measured temperature of each temperature measurement area in the target period, the temperature measurement result of the transformer is determined; among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0052] In one embodiment, as Figure 2 shown, a transformer temperature measurement method is provided. Taking the method applied to the Figure 1 terminal 102 as an example, the method includes the following steps:

[0053] S201, Detect the temperature of at least one temperature measurement area in the transformer to obtain the measured temperature of each temperature measurement area in the target period.

[0054] It should be noted that to ensure the effective acquisition of the effective measured temperature of each temperature measurement area in the transformer, different temperature measurement methods can be selected according to the actual situation of different temperature measurement areas to ensure targeted temperature detection for each temperature measurement area.

[0055] Among them, the selection of the temperature measurement area can be set or adjusted according to the actual temperature measurement requirements, and the specific area location corresponding to the temperature measurement area is not limited here.

[0056] In an embodiment of the present application, it may be pre-specified that the temperature measurement area includes at least one of the transformer winding area, the transformer core area, the transformer radiator area, and the transformer outer contour area. Further, when it is necessary to detect the temperature of at least one temperature measurement area in the transformer, the following may be included: detecting the temperature of the transformer winding area through the transformer winding measurement optical fiber to obtain the first measurement temperature of the transformer winding area in the measured temperature; detecting the temperature of the transformer core area through the transformer core measurement optical fiber to obtain the second measurement temperature of the transformer core area in the measured temperature; detecting the temperature of the transformer radiator area through a thermal resistor to obtain the third measurement temperature of the transformer radiator area in the measured temperature; detecting the temperature of the transformer outer contour area through an infrared thermal imager to obtain the fourth measurement temperature of the transformer outer contour area in the measured temperature.

[0057] Specifically, when it is necessary to measure the temperature of the transformer winding area and the transformer core area, the transformer winding measurement optical fiber and the transformer core measurement optical fiber may be installed, and the optical fiber lead-out wire may be pulled out, as Figure 3 shown. The optical fiber lead-out wire is connected to an optical fiber demodulator, and the optical fiber demodulator is connected to a computer through an optical fiber data line, and the optical fiber measurement temperature data is recorded by the computer.

[0058] When it is necessary to measure the temperature of the transformer radiator area, a thermal resistor may be installed at the temperature measurement point of the transformer radiator, and the thermal resistor wire is led out and connected to a thermal resistor data demodulator. The demodulator is connected to a computer through a data line, and the thermal resistor temperature measurement data is recorded by the computer, as Figure 4 shown.

[0059] When it is necessary to measure the temperature of the transformer outer contour area, as Figure 4 shown, an infrared thermal imager may be installed, and the position of the infrared thermal imager is set so that it can observe the entire transformer contour. The infrared thermal imager is set to take pictures at regular intervals to record the temperature change of the transformer.

[0060] S202. Determine the temperature measurement result of the transformer according to the temperature correlation relationship between the temperature measurement areas and the measured temperatures of the temperature measurement areas within the target period.

[0061] Among them, the temperature correlation relationship records the affected situation of the measured temperatures of other temperature measurement areas when the measured temperature of a certain temperature measurement area changes.

[0062] It should be noted that for the accuracy of the measured temperatures in each temperature measurement area within the target period, after obtaining the measured temperatures in each temperature measurement area within the target period, abnormal temperature detection can be performed on the measured temperatures in each temperature measurement area within the target period according to the temperature correlation relationship between the temperature measurement areas, so as to locate the abnormal temperatures included in the measured temperatures in each temperature measurement area within the target period. Furthermore, temperature correction is performed on the abnormal temperatures to obtain the accurate measured temperatures in each temperature measurement area within the target period, and the accurate measured temperatures in each temperature measurement area within the target period are used as the temperature measurement results of the transformer.

[0063] The above-mentioned transformer temperature measurement method obtains the measured temperatures in each temperature measurement area within the target period by performing temperature detection on at least one temperature measurement area in the transformer. Furthermore, according to the temperature correlation relationship between the temperature measurement areas and the measured temperatures in each temperature measurement area within the target period, the temperature measurement result of the transformer is determined. According to the above content, it can be seen that in this application, by performing temperature detection on at least one temperature measurement area in the transformer, separate temperature detection of each component inside the transformer is realized, ensuring that the measured temperatures in each temperature measurement area within the target period effectively reflect the actual measured temperatures of each part of the transformer. Through the temperature correlation relationship between the temperature measurement areas, effective query and correction of abnormal situations in the measured temperatures in each temperature measurement area within the target period are realized, preventing the existence of abnormal temperatures in the measured temperatures in each temperature measurement area within the target period due to detection deviation. Furthermore, through the temperature correlation relationship between the temperature measurement areas, the accurate temperature measurement results of each component in the transformer are effectively reflected, realizing an accurate reflection of the temperature distribution inside and outside the transformer.

[0064] In one embodiment, as Figure 5 shown, when it is necessary to determine the temperature measurement result of the transformer according to the temperature correlation relationship between the temperature measurement areas and the measured temperatures in each temperature measurement area within the target period, the following content may be included:

[0065] S501, perform abnormal temperature correction on the measured temperatures in each temperature measurement area within the target period according to the temperature correlation relationship between the temperature measurement areas to obtain the target temperatures in each temperature measurement area within the target period.

[0066] It should be noted that before performing abnormal temperature correction on the measured temperatures in each temperature measurement area within the target period, it is necessary to determine the abnormal temperatures from the measured temperatures in each temperature measurement area within the target period to ensure the smooth progress of temperature correction.

[0067] Specifically, when it is necessary to perform abnormal temperature correction on the measured temperatures of each temperature measurement area within a target period according to the temperature correlation relationship between the temperature measurement areas, the following may be included: determining abnormal temperatures from the measured temperatures of each temperature measurement area within the target period according to the temperature correlation relationship between the temperature measurement areas; determining the abnormal period corresponding to the abnormal temperature from the target period; determining the abnormal measurement area corresponding to the abnormal temperature from each temperature measurement area; performing temperature prediction on the abnormal measurement area within the abnormal period to obtain a corrected temperature; and performing abnormal temperature correction on the measured temperatures of each temperature measurement area within the target period according to the corrected temperature to obtain the target temperature of each temperature measurement area within the target period.

[0068] Among them, the temperature correlation relationship between each temperature measurement area may also record the maximum temperature difference between each temperature measurement area and other temperature measurement areas. Furthermore, when it is necessary to determine abnormal temperatures from the measured temperatures of each temperature measurement area within the target period according to the temperature correlation relationship between the temperature measurement areas, it is possible to verify whether the temperature differences between the measured temperatures of each temperature measurement area within the target period exceed the corresponding maximum temperature differences recorded in the temperature correlation relationship; if the temperature difference between two temperature measurement areas exceeds the corresponding maximum temperature difference recorded in the temperature correlation relationship starting from the first moment within the target period, and the temperature difference between the two temperature measurement areas is less than the corresponding maximum temperature difference recorded in the temperature correlation relationship starting from the second moment within the target period, when the temperature difference between the two temperature measurement areas exceeds the corresponding maximum temperature difference recorded in the temperature correlation relationship, the measured temperatures corresponding to the two temperature measurement areas are the abnormal temperatures, the period between the first moment and the second moment is the abnormal period corresponding to the abnormal temperature, and the two temperature measurement areas are the abnormal measurement areas corresponding to the abnormal temperature.

[0069] Further explanation, when it is necessary to perform temperature prediction on the abnormal measurement area within the abnormal period to obtain a corrected temperature, the following may be included: performing temperature prediction on the abnormal measurement area within the abnormal period according to the historical temperatures of each temperature measurement area within the historical period to obtain a corrected temperature.

[0070] In one embodiment of the present application, when it is necessary to predict the temperature of the abnormal measurement area during the abnormal period to obtain the corrected temperature, the historical temperatures of each temperature measurement area during the historical period can be obtained in advance. The historical temperatures record the historical temperatures of each temperature measurement area at different historical moments. Verify the similarity between the measured temperatures of other temperature measurement areas except the abnormal measurement area in the target period and the historical temperatures of each temperature measurement area at each historical moment. If the similarity between the historical temperatures of other temperature measurement areas except the abnormal measurement area at a certain historical moment and the measured temperatures of other temperature measurement areas except the abnormal measurement area is greater than the similarity threshold, then the historical temperature of the abnormal measurement area at this historical temperature is used as the corrected temperature.

[0071] In another embodiment of the present application, when it is necessary to predict the temperature of the abnormal measurement area during the abnormal period to obtain the corrected temperature, the historical temperatures of each temperature measurement area during the historical period can be obtained in advance. The historical temperatures record the historical temperatures of each temperature measurement area at different historical moments, and a temperature prediction model is trained based on the historical temperatures of each temperature measurement area at different historical moments. Then, the temperature of the abnormal measurement area during the abnormal period is predicted according to the temperature prediction model to obtain the corrected temperature.

[0072] S502. Determine the temperature measurement result of the transformer according to the target temperature of each temperature measurement area in the target period.

[0073] In one embodiment of the present application, after obtaining the target temperature of each temperature measurement area in the target period, the target temperature of each temperature measurement area in the target period can be used as the temperature measurement result of the transformer.

[0074] In another embodiment of the present application, after obtaining the target temperature of each temperature measurement area in the target period, the target temperature of each temperature measurement area in the target period can be subjected to view conversion, so as to convert the target temperature of each temperature measurement area in the target period into a view in a preset format, and the view in the preset format is used as the temperature measurement result of the transformer for information acquisition.

[0075] The above transformer temperature measurement method corrects the measured temperatures of each temperature measurement area during the target period for abnormal temperatures through the temperature correlation relationship between the temperature measurement areas, so as to obtain the target temperature of each temperature measurement area during the target period. Furthermore, based on the target temperature of each temperature measurement area during the target period, the temperature measurement result of the transformer is determined; effectively preventing abnormal temperatures from existing in the measured temperatures of each temperature measurement area during the target period due to detection deviation. Furthermore, through the temperature correlation relationship between the temperature measurement areas, the accurate temperature measurement results of each component in the transformer are effectively reflected, and the temperature distribution inside and outside the transformer is accurately reflected.

[0076] In one embodiment, as Figure 6 shown, when it is necessary to determine the temperature measurement result of the transformer, the following may be included:

[0077] S601, Use the optical fiber for measuring the transformer winding to detect the temperature of the transformer winding area, and obtain the first measured temperature of the transformer winding area in the measured temperature.

[0078] S602, Use the optical fiber for measuring the transformer core to detect the temperature of the transformer core area, and obtain the second measured temperature of the transformer core area in the measured temperature.

[0079] S603, Use the thermal resistor to detect the temperature of the transformer radiator area, and obtain the third measured temperature of the transformer radiator area in the measured temperature.

[0080] S604, Use the infrared thermal imager to detect the temperature of the transformer outer contour area, and obtain the fourth measured temperature of the transformer outer contour area in the measured temperature.

[0081] S605, Determine the abnormal temperature from the measured temperatures of each temperature measurement area during the target period according to the temperature correlation relationship between the temperature measurement areas.

[0082] S606, Determine the abnormal period corresponding to the abnormal temperature from the target period.

[0083] S607, Determine the abnormal measurement area corresponding to the abnormal temperature from each temperature measurement area.

[0084] S608, Predict the temperature of the abnormal measurement area during the abnormal period according to the historical temperatures of each temperature measurement area during the historical period, and obtain the corrected temperature.

[0085] S609, Correct the measured temperatures of each temperature measurement area during the target period according to the corrected temperature, and obtain the target temperature of each temperature measurement area during the target period.

[0086] S610. Determine the temperature measurement result of the transformer according to the target temperature of each temperature measurement area within the target period.

[0087] In the above transformer temperature measurement method, by detecting the temperature of at least one temperature measurement area in the transformer, the measured temperature of each temperature measurement area within the target period is obtained. Furthermore, according to the temperature correlation relationship between the temperature measurement areas and the measured temperature of each temperature measurement area within the target period, the temperature measurement result of the transformer is determined. According to the above content, it can be seen that in this application, by detecting the temperature of at least one temperature measurement area in the transformer, the individual temperature detection of each component inside the transformer is realized, ensuring that the measured temperature of each temperature measurement area within the target period effectively reflects the actual measured temperature of each part area of the transformer. Through the temperature correlation relationship between the temperature measurement areas, the effective query and correction of abnormal conditions in the measured temperature of each temperature measurement area within the target period are realized, preventing the existence of abnormal temperatures in the measured temperature of each temperature measurement area within the target period due to detection deviation. Furthermore, through the temperature correlation relationship between the temperature measurement areas, the accurate temperature measurement result of each component in the transformer is effectively reflected, realizing the accurate reflection of the temperature distribution inside and outside the transformer.

[0088] It should be understood that although each step in the flowcharts involved in the above embodiments is displayed in sequence according to the indication of the arrows, these steps do not necessarily need to be executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages. These steps or stages do not necessarily need to be executed at the same moment, but can be executed at different moments. The execution order of these steps or stages does not necessarily need to be sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.
