[0002] In recent years, with the rapid development of my country's power industry, power transformers have gradually shifted towards large capacity and high voltage. As the capacity and voltage of power transformers increase, the possibility of power transformer failure increases.

[0003] During the operation of dry-type transformers, temperature is an extremely important monitoring quantity. When the transformer operates under high temperature, its insulation will be affected, thus affecting the overall service life of the transformer. In recent years, transformer overheating failures have accounted for a very large proportion of the total number of failures. Therefore, effective implementation of online monitoring of transformer temperature is of great significance to ensure the safe and stable operation of the transformer.

[0004] In the related art, when the temperature inside the transformer is monitored, the temperature measurement location is a small temperature measurement point, and only the temperature of the upper part of the transformer can be measured. If it is a local high temperature, it is difficult to detect. Even if there is oil circulation, the local high temperature will be absorbed by a large amount of oil. When the temperature is fed back to the detection part, the temperature change may not be large. Once the transformer temperature overheats, it cannot be discovered in time, which can easily cause the transformer to overheat and fail, which is not conducive to the reliability of temperature monitoring.

[0035] Example 1

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] The present invention provides a transformer infrared temperature matrix detection device, which includes a transformer 1 and a detection component 2. The transformer 1 is provided with a plurality of linearly distributed pipelines 11. The detection component 2 is located inside the pipeline 11 and connected to a winding component 3. The detection component 2 is an infrared sensor, and an ARM cortexM4 core MCU is used as a control and calculation unit to read sensor data and perform analysis.

[0038] Its infrared sensor obtains the measurement data of the infrared temperature sensor, and the sensor data update rate is 16Hz, that is, it can read the infrared dot matrix data 16 times per second;

[0039] The obtained dot matrix data is subjected to the Sobel operator to obtain the edges between the heating parts of the dot matrix data;

[0040] Perform weighted filtering on the obtained data matrix. During use, traverse the temperature in the framed area to obtain the point with the highest temperature, determine the problem of the 8 adjacent points around it, perform weighted filtering, and obtain the temperature value;

[0041] The temperature array data obtained by the infrared sensor is a 320x240 dot matrix. The Sobel operator is a discrete differential operator for images. By performing horizontal and vertical plane convolution on the input temperature array data, the gradient values ​​in the parallel and vertical directions are obtained. Through integration, the edge of the area with greater heat in the array can be obtained, and the coordinates of the heat area can be confirmed by comparing the data around the boundary.

[0045] The area framed by the edge is traversed to obtain the point with the highest temperature in the area. The actual temperature of the area is obtained by weighted mean filtering the matrix of this point and the adjacent 8 points. The kernel used for mean filtering is

[0046] The pipeline 11 is located in the transformer 1 and submerged in the cooling oil and is arranged horizontally, and the pipeline 11 is in contact with the inner wall of the transformer 1;

[0047] The detection component 2 is located in the pipeline 11 and is connected to the winding component 3 through a traction rope 31. The winding component 3 includes a rotating shaft 32, a first winding roller 33, and a second winding roller 34. The first winding roller 33 and the second winding roller 34 are respectively located at two ends of the rotating shaft 32. Two ends of the traction rope 31 are respectively wound around the first winding roller 33 and the second winding roller 34. The first winding roller 33 is fixedly connected to the rotating shaft 32, and the second winding roller 34 is connected to the rotating shaft 32 through a gear set 35.

[0048] The gear set 35 includes a first gear 351 and a second gear 352. The center of the second winding roller 34 is an internal gear. The second gear 352 and the second winding roller 34 are meshed with each other. The first gear 351 passes through the rotating shaft 32 and is meshed with the second gear 352. The second winding roller 34 is driven to rotate by the gear set 35 and its rotation direction is opposite to that of the first winding roller 33. Multiple rotating shafts 32 are driven to rotate by motors.

[0049] When the present embodiment is in use, the transformer 1 starts to work, the detection component 2 is submerged in the cooling oil, the motor drives the rotating shaft 32 to rotate, the rotating shaft 32 drives the first winding roller 33 and the second winding roller 34 to rotate, and under the action of the gear set 35, the first winding roller 33 and the second winding roller 34 rotate in opposite directions, the first winding roller 33 pays off the traction rope 31, and the second winding roller 34 tightens the traction rope 31, and the mutual cooperation between the first winding roller 33 and the second winding roller 34 drives the detection component 2 to move in the pipeline 11, thereby realizing the continuous or intermittent measurement of the temperature of different points in the pipeline 11 by the detection component 2, and timely discovering potential temperature anomalies.

[0050] Compared with the prior art, the first winding roller 33 and the second winding roller 34 in the winding assembly 3 can cooperate with each other to drive the detection assembly 2 to move in the pipeline 11, so as to realize continuous or intermittent measurement of the temperature at different points inside the transformer, which is helpful to timely discover potential temperature anomalies, thereby preventing failures caused by overheating of the transformer. The detection assembly 2 is located inside the pipeline 11 and is in direct contact with the transformer oil, so it can more accurately measure the temperature of the transformer oil. At the same time, the infrared sensor has the characteristics of non-contact measurement, which can avoid errors and damage caused by contact measurement. Since the detection assembly 2 is connected to the winding assembly 3 by a traction rope 31 and moves in the pipeline 11, it is not necessary for personnel to enter the transformer for manual detection, thereby greatly improving the safety of the detection process, reducing manual intervention, and improving detection efficiency and accuracy. When in use, it can adapt to transformers of different sizes and shapes. It only needs to adjust the length and distribution of the pipeline 11 and the parameters of the winding assembly 3 to realize temperature detection of different types of transformers.

[0051] Example 2

[0052] In the above embodiment, the detection component 2 cannot accurately locate the high-temperature part during the temperature detection process. Therefore, the embodiment of the present application optimizes the detection component 2 to a certain extent based on the above embodiment.

[0053] In this embodiment, the detection component 2 is provided with a first airbag 21, the transformer 1 is provided with an air pump corresponding to the first airbag 21, and the pipeline 11 is provided with a plurality of through holes 111, and the plurality of through holes 111 are linearly distributed on the pipeline 11;

[0054] The diameter of the first airbag 21 is determined according to the inner diameter of the pipeline 11 and the outer diameter of the detection component 2. Assuming that the inner diameter of the pipeline is D mm and the outer diameter of the detection component 2 is d mm, the diameter of the airbag can be designed to be (Dd-2×δ) mm, where δ is the gap between the airbag and the pipeline and the detection component, which is usually 1-2 mm. The length is determined according to the maximum distance that the detection component 2 needs to move in the pipeline 11 and the expansion rate of the airbag. Assuming that the maximum distance that the detection component 2 needs to move is L mm and the expansion rate of the airbag is ε (usually 1.2-1.5), the length of the airbag can be designed to be (L / ε+2×safety margin) mm, where the safety margin is the extra length set to prevent excessive expansion of the airbag. The first airbag 21 is made of a material that is resistant to high temperature, corrosion, good in elasticity and wear-resistant. The thickness of the first airbag 21 is determined according to the pressure it can withstand, wear resistance and material properties. Assuming that the design pressure of the airbag is PPa and the allowable stress of the material is σMPa, the thickness of the airbag can be calculated by the formula t=P / (σ×safety factor), where the safety factor is an additional factor set to prevent the airbag from rupturing, usually 1.5-2.0.

[0055] When the present embodiment is in use, the cooling oil enters the interior of the pipe 11 through the through hole 111. The detection component 2 can directly detect the temperature of the oil during the temperature detection process to prevent local high temperature from being absorbed by the cooling oil. When the detection component 2 detects a temperature abnormality, the first airbag 21 is inflated or deflated, and the first airbag 21 drives the detection component 2 to move up and down in the pipe 11 to detect whether the temperature abnormality is in the upper through hole cooling oil or the lower through hole cooling oil, so as to further determine the location of the temperature abnormality, narrow the scope of investigation, and concentrate efforts on repairing specific areas.

[0056] Compared with the prior art, by providing a plurality of through holes 111 on the pipe 11, the cooling oil can directly enter the interior of the pipe 11 and contact the detection component 2. In this way, the detection component 2 can directly detect the temperature of the oil, avoiding the detection error caused by the local high temperature being absorbed by the cooling oil, and improving the accuracy and reliability of the temperature detection. By inflating or deflating the first airbag 21, the detection component 2 can be driven to move up and down in the pipe 11. In this way, the temperature of the cooling oil at the upper through hole and the lower through hole can be detected respectively, so as to quickly determine the specific location of the temperature anomaly. This helps to narrow the scope of investigation, concentrate efforts on maintenance of specific areas, and improve maintenance efficiency and accuracy. By quickly locating the location of the temperature anomaly, maintenance personnel can find the problem more quickly and perform targeted maintenance. This avoids the waste of time and resources caused by blind maintenance and improves maintenance efficiency.

[0057] Example 3

[0058] During the temperature detection by the detection component 2 in the above embodiment, since the first airbag 21 is provided with a plurality of through holes 111, temperature differences are easily generated during detection, which affects the accuracy of the temperature detection by the detection component 2. Therefore, the embodiment of the present application optimizes the detection component 2 to a certain extent based on the above embodiment.

[0059] In this embodiment, second airbags 22 are provided on both sides of the detection component 2. The second airbags 22 are connected to the air pump. The air pump controls the second airbags 22 to expand and contact the inner wall of the pipeline 11 to seal the cooling oil at both ends of the detection component 2, thereby preventing the cooling oil at both ends of the detection component 2 from flowing and causing a temperature difference in the detection temperature of the detection component 2.

[0060] When this embodiment is used and temperature anomalies are detected or during fixed-point detection, the second airbag 22 is inflated by an air pump, and the second airbag 22 begins to expand and contact the inner wall of the pipe 11 to seal the cooling oil at both ends of the detection component 2, thereby ensuring that the detection component 2 is in a relatively stable environment during the temperature measurement process, reducing the temperature difference caused by changes in external conditions and avoiding the flow of cooling oil on both sides of the detection component 2, thereby improving the stability of the temperature measurement data and affecting the detection of the detection component 2, and the second airbag 22 also plays a certain protective role, avoiding direct collision between the detection component 2 and the inner wall of the pipe or other objects during movement, thereby extending the service life of the detection component 2.

[0061] Compared with the prior art, the second airbag 22 expands and contacts the inner wall of the pipe 11, effectively blocking the flow of cooling oil at both ends of the detection component 2. This ensures that the detection component 2 is in a relatively stable environment during the temperature measurement process, reducing the impact of changes in external conditions (such as cooling oil flow) on the temperature measurement data. Thereby improving the accuracy and reliability of the temperature measurement data, the blocking effect of the second airbag 22 not only reduces the temperature difference, but also stabilizes the working environment of the detection component 2, allowing the detection component 2 to capture and record temperature data more accurately when performing fixed-point detection or discovering temperature anomalies, and the second airbag 22 prevents the detection component 2 from directly colliding with the inner wall of the pipe or other objects during movement, thereby reducing the risk of wear and damage and extending the service life of the detection component 2.

[0062] Example 4

[0063] During the temperature detection by the detection component 2 in the above embodiment, the detection component 2 is restricted by the pipeline 11 inside the pipeline 11. Although the through hole 111 is provided on the pipeline 11, it can be determined whether the temperature abnormality occurs above or below the pipeline 11, but there is still a blind spot in the detection. Therefore, the embodiment of the present application optimizes the detection component 2 to a certain extent based on the above embodiment.

[0064] In this embodiment, the detection component 2 is provided with a guide wire component 23, the head of the guide wire component 23 is fixed to the traction rope 31 by a buckle 24, the tail of the guide wire component 23 extends to the operation box 12 on one side, and the pipeline 11 is provided with a plurality of linearly distributed notches 112 corresponding to the detection component 2 and the second airbag 22;

[0065] The guide wire assembly 23 includes a flexible guide wire 231 and a rigid guide wire 232. The two ends of the flexible guide wire 231 are provided with a bending tube 2311 and a first adjustment tube 2312 connected to each other. The bending tube 2311 is flexible and can be bent relatively easily in a normal state. The rigid guide wire 232 sequentially passes through the first adjustment tube 2312, the flexible guide wire 231, and the bending tube 2311. The tail of the rigid guide wire 232 is provided with a second adjustment tube 2321 corresponding to the first adjustment tube 2312.

[0066] A rotating disk 2313 is provided on the top of the first adjusting tube 2312, the rotating disk 2313 is fixedly connected to the flexible guide wire 231 and rotatably connected to the first adjusting tube 2312, and the second adjusting tube 2321 passes through the first adjusting tube 2312 and is connected to the first adjusting tube 2312 by threads;

[0067] A fixed plate 36 is provided on the rotating shaft 32, and the fixed plate 36 is connected to the first gear 351 through a telescopic rod 361, and the first gear 351 is slidably connected to the rotating shaft 32 through the telescopic rod 361. A third gear 353 meshing with the second winding roller 34 is provided on the rotating shaft 32, and the third gear 353 is connected to the first gear 351 through a connecting rod 362, and the third gear 353 is slidably connected to the rotating shaft 32;

[0068] Sensors are provided on the bending tube 2311 and the notch 112 , and a display screen connected to the sensors on the bending tube 2311 and the notch 112 and the detection component 2 is provided on the operation box 12 .

[0069] When the present embodiment is in use and abnormal temperature is detected, the positions of the guide wire assembly 23 and the detection assembly 2 are observed through the display screen, and the gap 112 adjacent to the detection assembly 2 is determined. The telescopic rod 361 begins to contract to drive the first gear 351 and the third gear 353 to move. The first gear 351 is not meshed with the second gear 352, and the third gear 353 is meshed with the second winding roller 34 to drive the second winding roller 34 to rotate, so that the second winding roller 34 and the first winding roller 33 start to release the wire synchronously, and the detection assembly 2 is driven to move by the guide wire assembly 23, and the rigid guide wire 232 is moved backward by rotating the second adjustment tube 232 backward, without The top of the bending tube 2311 is then supported, and the bending tube 2311 is bent. The flexible guide wire 231 and the bending tube 2311 are driven to rotate in a circle by rotating the rotating disk 2313 to adjust the bending angle of the bending tube 2311. The detection component 2 and the second airbag 22 are brought out of the pipeline 11 through the notch 112, so that the detection component 2 can more flexibly reach the hard-to-reach areas inside the transformer 1, and the internal temperature of the transformer 1 is further monitored. The first winding roller 33 and the second winding roller 34 are rotated in the opposite direction by the rotating shaft 32 to be tightened synchronously, so that the detection component 2 and the second airbag 22 are pulled into the pipeline 11 to continue the temperature detection.

[0070] Compared with the prior art, by providing a guide wire assembly 23, especially one including a flexible guide wire 231 and a rigid guide wire 232, the detection assembly 2 can be moved more flexibly. The bending tube 2311 of the flexible guide wire 231 can be easily bent when not supported by the rigid guide wire 232, so as to adapt to the complex and hard-to-reach areas inside the transformer 1. The presence of the rigid guide wire 232 ensures that the guide wire assembly 23 can maintain a certain rigidity and stability when necessary, which is convenient for accurately controlling the position of the detection assembly 2. The threaded connection between the second adjustment tube 232 and the first adjustment tube 2312 and the design of the rotating disk 2313 allow the user to easily adjust the bending angle and position of the flexible guide wire 231 and the bending tube 2311, further improving the flexibility of the system. By setting a sensor and a display screen connected to the detection component 2, the user can monitor the temperature inside the transformer 1 in real time. By setting the telescopic rod 361 and the connecting rod 362, the user can conveniently control the sliding connection between the first gear 351 and the third gear 353, thereby realizing the rotation and wire-releasing operation of the second winding roller 34. The reverse rotation of the rotating shaft 32 can synchronously tighten the first winding roller 33 and the second winding roller 34, and pull the detection component 2 and the second airbag 22 back into the pipeline 11 to continue temperature monitoring. This not only improves the flexibility and accuracy of temperature monitoring inside the transformer 1, but also simplifies the operation process and improves work efficiency.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.

When a temperature abnormality is found or a fixed-point detection is performed, the second airbag 22 is inflated. After the second airbag 22 expands, it contacts the inner wall of the pipe 11, and the cooling oil at both ends of the detection component 2 is blocked to ensure that the detection component 2 is in a relatively stable environment during the temperature measurement process; S4, recording the temperature data measured by the detection component 2 at different points; S5. Analyze the data to find out the cause and location of the temperature anomaly.
