[0002] With the increasing energy demand in modern society, transformers, as key power transmission equipment in power systems, require particularly effective and safe operation in a cost-effective manner. During transformer operation, coolers are typically used to lower the transformer's temperature and ensure its normal operation. However, if a cooler malfunctions, it can affect the transformer's stability. Therefore, it is necessary to monitor the temperature and oil flow rate in various areas of the cooler to determine its operational status.
[0003] In traditional technology, each area of the cooler is usually tested one by one to determine the cooler's operating status. However, since the temperature and oil flow rate in some areas may change rapidly, the test results obtained by traditional technology may be delayed and cannot reflect the cooler's operating status in real time, thus resulting in low detection accuracy.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0054] In one embodiment, such as Figure 1 As shown, a method for detecting a cooler fault is provided, including the following steps:
[0055] S101 acquires real-time temperature data and real-time oil flow rate data for each area of the cooler under real-time operating conditions.
[0056] The real-time temperature data for each area of the cooler can include the real-time temperature data of areas such as the cooler's outer shell, heat sinks, and oil flow pipes; the real-time oil flow velocity data for each area of the cooler can include the real-time oil flow velocity data of areas such as the connection points of each heat sink, the oil inlets of each heat sink, the connection points between the oil tank and the cooler's outer shell, and the location of the oil pump, etc.
[0057] Optionally, multiple infrared temperature sensors can be used to monitor the cooler in real time from the front, back, left, and right sides to obtain real-time temperature data of each area of the cooler under real-time operating conditions.
[0058] Optionally, multiple oil flow velocity sensors can be used to monitor the oil flow velocity in each area of the cooler in real time, thereby obtaining real-time oil flow velocity data for each area of the cooler under real-time operating conditions.
[0059] S102, construct a real-time temperature distribution database based on real-time temperature data, and construct a real-time oil flow velocity database based on real-time oil flow velocity data.
[0060] The real-time temperature distribution database stores real-time temperature data for various areas of the cooler under real-time operating conditions, such as the real-time temperature data for areas like the cooler's casing, radiator fins, and oil flow pipes. The real-time oil flow rate database stores real-time oil flow data for various areas of the cooler under real-time operating conditions, such as the real-time oil flow rate data for areas like the cooler's radiator inlet and outlet, the connection points of each radiator fin, the connection point between the oil tank and the cooler casing, and the location of the oil pump.
[0061] S103, compare the real-time temperature distribution database with the preset standard temperature distribution database to determine if there is a temperature fault area; and compare the real-time oil flow velocity database with the preset standard oil flow velocity database to determine if there is an oil flow velocity fault area.
[0062] The standard temperature distribution database stores standard temperature data for each region of the cooler under different operating conditions; the standard oil flow rate database stores standard oil flow rate data for each region of the cooler under different operating conditions.
[0063] Optionally, real-time temperature data and standard temperature data for each region of the cooler can be extracted from a real-time temperature distribution database and a standard temperature distribution database, respectively. The real-time temperature data and standard temperature data for the same region of the cooler under the same operating conditions can be compared. If the absolute value of the difference between the real-time temperature data and the standard temperature data is greater than or equal to a preset fault temperature threshold, then this region is determined to be a temperature fault region. Simultaneously, the real-time temperature data and standard temperature data for each region of the cooler can be compared to determine whether a temperature fault region exists in the cooler.
[0064] For example, suppose that under a certain operating condition, the coordinates of a certain area in the cooler in the spatial coordinate system are (i, j, k), where i, j, and k are the coordinate values of the x, y, and z directions in the spatial coordinate system, respectively, and let T... c,ijk For the real-time temperature data of this area, T f,ijk For the standard temperature data of this region, T ε If |T is the preset fault temperature threshold, then... f,ijk —T c,ijk |≥T ε Then this region (i, j, k) is the temperature fault region; if |T f,ijk —T c,ijk |<T ε If so, then this region (i, j, k) is not a temperature fault region.
[0065] Optionally, real-time oil flow rate data and standard oil flow rate data for each region of the cooler can be extracted from a real-time oil flow rate database and a standard oil flow rate database, respectively. The real-time oil flow rate data and standard oil flow rate data for the same region of the cooler under the same operating conditions can be compared. If the absolute value of the difference between the real-time oil flow rate data and the standard oil flow rate data is greater than or equal to a preset fault oil flow rate threshold, then this region is determined to be an oil flow rate fault region. Simultaneously, the real-time oil flow rate data and standard oil flow rate data for each region of the cooler can be compared to determine whether there are any oil flow rate fault regions in the cooler.
[0066] For example, suppose that under a certain operating condition, the coordinates of a certain area in the cooler in the spatial coordinate system are (i, j, k), where i, j, and k are the coordinate values of the x, y, and z directions in the spatial coordinate system, respectively, and let v f,x,ijk v f,y,ijk v f,z,ijkThese represent the velocity components in the x, y, and z directions at the standard oil flow rate in this region, respectively. c,x,ijk v c,y,ijk v c,z,ijk These represent the velocity components in the x, y, and z directions, respectively, of the real-time oil flow velocity in this region. ε For the preset fault oil flow velocity threshold, if max(|v f,x,ijk —v c,x,ijk |,|v f,y,ijk —v c,y,ijk |,|v f,z,ijk —v c,z,ijk |)≥V ε Then this region (i, j, k) is the oil flow velocity fault region; if max(|v f,x,ijk —v c,x,ijk |,|v f,y,ijk —v c,y,ijk |,|v f,z,ijk —v c,z,ijk |)<V ε If so, then this region (i, j, k) is not a region with a faulty oil flow velocity.
[0067] S104, construct a three-dimensional geometric model of the cooler; when a temperature fault area exists, perform a digital twin display of the temperature fault area based on the three-dimensional geometric model of the cooler; and when an oil flow velocity fault area exists, perform a digital twin display of the oil flow velocity fault area based on the three-dimensional geometric model of the cooler.
[0068] Digital twin display refers to accurately and vividly displaying the temperature and oil flow rate distribution of the operating cooler to the inspection personnel in the constructed three-dimensional geometric model of the cooler. This allows the inspection personnel to grasp the real-time temperature and oil flow rate distribution of each area of the cooler based on the three-dimensional geometric model of the cooler, and to quickly identify the corresponding temperature fault area and oil flow rate fault area when the cooler malfunctions, thereby improving the accuracy of the inspection.
[0069] The cooler fault detection method in this embodiment acquires real-time temperature data and real-time oil flow velocity data for each area of the cooler under real-time operating conditions. It constructs a real-time temperature distribution database based on the real-time temperature data and a real-time oil flow velocity database based on the real-time oil flow velocity data. The real-time temperature distribution database is then compared with a preset standard temperature distribution database to determine if a temperature fault area exists. Similarly, the real-time oil flow velocity database is compared with a preset standard oil flow velocity database to determine if an oil flow velocity fault area exists. Furthermore, a three-dimensional geometric model of the cooler is constructed. When a temperature fault area exists, a digital twin representation of that area is created based on the three-dimensional geometric model. When an oil flow velocity fault area exists, a digital twin representation of that area is also created based on the three-dimensional geometric model. This allows for real-time detection of temperature and oil flow velocity data for each area of the cooler and real-time digital twin representation of the corresponding fault areas, thereby improving detection accuracy.
[0070] In one embodiment, such as Figure 2 As shown, a preset standard temperature distribution database and a preset standard oil flow velocity database are constructed, including:
[0071] S201, construct a two-way coupled calculation model of temperature field and flow field, and obtain the operating parameters of each region of the cooler under different operating conditions.
[0072] The temperature field-flow field bidirectional coupling calculation model is used to calculate the standard temperature distribution data and standard oil flow velocity data of each area of the cooler under different operating conditions. It can be constructed by calculation software that can quickly, accurately and vividly calculate the temperature and oil flow velocity distribution of the cooler. The operating parameters can include parameters such as season, day and night, and load rate.
[0073] S202, input the operating parameters into the temperature field-flow field bidirectional coupling calculation model to obtain the standard temperature distribution database and the standard oil flow velocity database.
[0074] In one embodiment, such as Figure 3 As shown, the above S202 includes:
[0075] S2021, input the operating parameters into the temperature field-flow field bidirectional coupling calculation model to obtain standard temperature data and standard oil flow velocity data for each region of the cooler.
[0076] S2022, construct a standard temperature distribution database based on the standard temperature data of each area of the cooler under different operating conditions, and construct a standard oil flow velocity database based on the standard oil flow velocity data of each area of the cooler under different operating conditions.
[0077] In one embodiment, such as Figure 4 As shown, the three-dimensional geometric model of the aforementioned cooler includes:
[0078] S401, obtain the dimensional data of each component of the cooler, and establish a dimensional database of the cooler based on the dimensional data.
[0079] The cooler components may include an oil tank, heat sink, oil flow pipes, oil pump, fan, and cooler body, etc. The cooler dimensional database can store dimensional data for different models of coolers, including oil tank dimensions, heat sink dimensions, oil flow pipe dimensions, oil pump dimensions, fan dimensions, and cooler body dimensions, etc. Therefore, this application can also construct three-dimensional geometric models of different cooler models through the dimensional database, thereby adapting to different application scenario requirements.
[0080] S402, construct a three-dimensional geometric model of the cooler based on the actual operating cooler's dimensional data.
[0081] Different models of coolers may have different component configurations, and the dimensions of each component may also differ. Optionally, the model of an actual operating cooler can be input into a cooler dimension database to obtain the actual operating cooler's dimension data, thereby constructing a three-dimensional geometric model of the cooler.
[0082] In one embodiment, the cooler fault detection method further includes: if a temperature fault area exists, and / or an oil flow rate fault area exists, an alarm is triggered, thereby promptly informing the testing personnel to quickly conduct further investigation and repair work on the temperature fault area and / or the oil flow rate fault area of the cooler.
[0083] In one embodiment, such as Figure 5 As shown, the fault detection method for the cooler also includes:
[0084] S501 If there is no temperature fault area, then a digital twin display of the real-time temperature data of each area of the cooler is performed based on the three-dimensional geometric model of the cooler.
[0085] S502 If there is no oil flow velocity fault area, then the real-time oil flow velocity data of each area of the cooler is displayed digitally based on the three-dimensional geometric model of the cooler.
[0086] Since there are no temperature fault areas and / or oil flow rate fault areas, this embodiment can also digitally twin the real-time temperature data and real-time oil flow rate data of each area of the cooler based on the three-dimensional geometric model of the cooler. Thus, this embodiment can also reflect the operating status of each area of the cooler in real time, accurately and vividly, thereby further improving the detection accuracy.
[0087] To facilitate understanding by those skilled in the art, the following provides a detailed description of the cooler fault detection method provided in this application. Please refer to [link / reference]. Figure 6 The method may include:
