[0027] An embodiment of the present invention provides an intelligent monitoring device for a wind power box transformer, which is applied to a transformer room 110 of a wind power box transformer 100. A transformer 200 is arranged in the transformer room 110. The outer periphery and the top of the transformer 200 are respectively set as a heat dissipation area 210 and a wiring area 220. The device comprises a circular track 1, a camera mechanism 2, a temperature and humidity sensor 5 and a control module 7. The circular track 1 and the temperature and humidity sensor 5 are arranged in the transformer room 110. The camera mechanism 2 is movably arranged on the circular track 1. The camera mechanism 2 is used to collect image information of the wiring area 220. The circular track 1 and the temperature and humidity sensor 5 can both move vertically (Z-axis direction in the figure), and when the circular track 1 moves downward, the temperature and humidity sensor 5 can move upward. The temperature and humidity sensor 5 is used to collect temperature and humidity information in the transformer room 110. The control module 7 comprises a voltage transformer 72 and a current transformer 73. The voltage transformer 72 and the current transformer 73 are both connected to the circuit of the wiring area 220 to collect voltage and current information on the circuit of the wiring area 220.

[0028] Specifically, usually the transformer 200 only occupies the lower space of the transformer chamber 110, while the upper space in the transformer chamber 110 is very ample. The present solution is designed based on this point and will not interfere with the normal operation of the transformer 200. It should be noted that the heat dissipation area 210 and the wiring area 220 are not conventional terms for the transformer 200. They are only for the convenience of explaining the present solution. The heat dissipation area 210 refers to the outer surface of the main part of the transformer 200. This area is the main channel for the heat dissipation of the transformer 200. The transformer 200 will generate a large amount of heat during operation, and the heat needs to be dissipated through heat sinks, heat pipes or natural convection. Dissipate to maintain the normal operating temperature of the transformer 200; the wiring area 220 refers to the area on the transformer 200 used to connect the input and output wires. This area is usually located above the transformer 200 to facilitate connection with the power grid or other equipment. The wiring area 220 usually includes high-voltage bushings, low-voltage bushings, wiring terminals and other components, as well as related connection devices and protection equipment. It should be noted that the specific range of the heat dissipation area 210 may vary depending on the design and manufacturing method of the transformer 200. This case only applies to the situation where the heat dissipation area 210 and the wiring area 220 are located at the periphery and top of the transformer 200 respectively.

[0029] In this optional embodiment, the camera mechanism 2 is movably arranged on the circular track 1, so that the camera mechanism 2 moves on the circular track 1, so that the camera mechanism 2 can shoot key components such as high-voltage bushings, low-voltage bushings, and terminal blocks on the wiring area 220 from different angles and positions. The all-round and multi-angle shooting helps the staff to more accurately judge the fault condition of the wiring area 220, and improve the efficiency of fault detection and processing; the circular track 1 and the temperature and humidity sensor 5 can both move vertically, and the moving directions of the two are opposite. When the circular track 1 moves down, the temperature and humidity sensor 5 moves up, and the temperature and humidity information at a higher position inside the transformer room 110 can be collected, so that the temperature and humidity information at different heights inside the transformer room 110 can be collected, which helps to have a more comprehensive understanding of the transformer room 110. environmental conditions, providing data support for the operation and maintenance of the transformer 200. The downward movement of the circular track 1 also drives the camera mechanism 2 to move downward, close to the heat dissipation area 210, which helps to defog the lens of the camera mechanism 2 under special circumstances (such as when the humidity in the transformer room 110 is high) to ensure the shooting quality, thereby improving the reliability and practicality of the camera mechanism 2; the voltage transformer 72 and the current transformer 73 can collect the voltage and current information on the circuit in the wiring area 220 in real time, so as to timely discover abnormal conditions in the circuit (such as overload, short circuit, etc.), and provide strong guarantee for the safe and stable operation of the transformer 200. In summary, the above technical solution improves the intelligent monitoring level of the transformer 200 in the wind power box transformer 100, and provides strong support for the operation and maintenance management of the wind farm.

[0030] Optionally, the intelligent monitoring device of the wind turbine box transformer also includes a linkage mechanism 6. When the circular track 1 moves downward, the linkage mechanism 6 is used to drive the temperature and humidity sensor 5 to move upward. For example, the linkage mechanism 6 may include a fixed pulley 61, a pull rope 62, a second slide bar 63 and a slider 64. The second slide bar 63 is vertically arranged in the transformer chamber 110, and the slider 64 is slidably connected to the second slide bar 63. The temperature and humidity sensor 5 is connected to the slider 64. The fixed pulley 61 is arranged above the transformer chamber 110, one end of the pull rope 62 is connected to the slider 64, and the other end of the pull rope 62 is connected to the circular track 1 after passing around the fixed pulley 61.

[0031] In this optional embodiment, combined with Figure 1 , Figure 2 and Figure 3 As shown, the fixed pulley 61 can be installed on the bottom surface of the shell above the transformer chamber 110 through a rotating seat. When the circular track 1 moves downward, the pull rope 62 pulls the slider 64 upward along the second slide bar 63 under the guidance of the fixed pulley 61, thereby moving the temperature and humidity sensor 5 toward the top of the transformer chamber 110, so that the temperature and humidity sensor 5 can collect the temperature and humidity at different heights inside the transformer chamber 110. When the circular track 1 moves upward, the temperature and humidity sensor 5 and the slider 64 move downward along the second slide bar 63 due to their own gravity, so that the temperature and humidity sensor 5 can be restored to its original position.

[0032] Furthermore, the camera mechanism 2 includes a monitoring camera 21, a mounting seat 23 and an electric trolley 24. The electric trolley 24 is disposed on the circular track 1. The electric trolley 24 is used to move along the track of the circular track 1. The mounting seat 23 is connected to the bottom of the electric trolley 24. The monitoring camera 21 is disposed on the mounting seat 23. The monitoring camera 21 is used to shoot the wiring area 220.

[0033] In this optional embodiment, combined with Figure 4 and Figure 5 As shown, the electric trolley 24 can be driven by a battery, and the circular track 1 has a track groove for the wheels of the electric trolley 24 to roll. The electric trolley 24 drives the monitoring camera 21 to move in a circular direction, so that the monitoring camera 21 can obtain different viewing angles of the wiring area 220, thereby taking all-round shots of the high-voltage bushings, low-voltage bushings, wiring terminals and other components on the wiring area 220, thereby facilitating the staff to make fault judgments.

[0034] Optionally, the camera mechanism 2 further includes an electric push rod 22 , the monitoring camera 21 is rotatably connected to the mounting seat 23 , the mounting end of the electric push rod 22 is rotatably connected to the mounting seat 23 , and the extended end of the electric push rod 22 is rotatably connected to the monitoring camera 21 .

[0035] In this embodiment, in this optional embodiment, combined with Figure 5As shown, the monitoring camera 21 is pushed to rotate by the electric push rod 22, so that the shooting angle of the monitoring camera 21 can be adjusted to facilitate accurate shooting of high-voltage bushings, low-voltage bushings, terminal blocks and other components on the wiring area 220, which is convenient for staff to view remotely.

[0036] Furthermore, combined with Figure 4 , Figure 5 and Figure 6 As shown, the control module 7 also includes a controller 71, a data collector 74 and a communication module 75. The voltage transformer 72, the current transformer 73 and the temperature and humidity sensor 5 are all electrically connected to the data collector 74. The monitoring camera 21 is electrically connected to the communication module 75. The data collector 74 is electrically connected to the communication module 75. The communication module 75 is electrically connected to the controller 71. The electric trolley 24 and the electric push rod 22 are both electrically connected to the controller 71.

[0037] In this optional embodiment, combined with Figure 2 , Figure 3 and Figure 6 As shown, the controller 71 can control the start and stop of the electric trolley 24 and the electric push rod 22. The control module 7 can also include a user interface (such as a touch screen, a display, etc.) for displaying real-time monitoring data, alarm information, historical records, etc., so as to facilitate remote monitoring and management by staff;

[0038] The voltage transformer 72 is connected to the high voltage side or the low voltage side of the transformer 200 to convert the high voltage into a low voltage signal. The current transformer 73 is connected to the input and output terminals of the transformer 200 to convert the high current into a low current signal. The converted voltage and current signals are collected by the data collector 74. The data collector 74 can be an analog-to-digital converter (ADC) to convert the analog signal into a digital signal for subsequent processing. The collected digital signal is transmitted to the controller 71 through the communication module 75 (such as Ethernet, etc.). The controller 71 processes and analyzes the received signal, which may include filtering, calibration, calculation and other steps to obtain accurate voltage and current information. The controller 71 compares the processed voltage and current information with the preset threshold value. If it exceeds the range, an alarm is triggered to remind the staff to take corresponding protective measures.

[0039] The monitoring camera 21 captures real-time images at the location of the wiring area 220, especially the high-voltage bushing, low-voltage bushing, wiring terminals and other components on the wiring area 220, as well as related connection devices and protection equipment. The captured image is transmitted to the controller 71 of the control module 7 through the built-in communication component or the external communication line. The controller 71 analyzes the received image, for example, it may include steps such as image recognition and abnormality detection. If the monitoring camera 21 detects an abnormality in the wiring area 220 (such as damage to components such as high-voltage bushings, low-voltage bushings, wiring terminals, etc.), an alarm is triggered to remind the staff. The staff can also directly view the real-time shooting picture to judge the problems of components such as high-voltage bushings, low-voltage bushings, wiring terminals, such as loose wiring, which can be judged by the naked eye.

[0040] The temperature and humidity sensor 5 is installed in the transformer room 110, and is used to monitor the temperature and humidity in the transformer room 110 in real time. The collected temperature and humidity data are converted and collected by the data collector 74, and the collected temperature and humidity data are transmitted to the controller 71 through the communication module 75. The controller 71 processes and analyzes the received data, including calculating the average value, judging whether it is within the safety range, etc. If the temperature and humidity data exceeds the preset safety range, the controller 71 triggers an alarm to remind the staff to take corresponding protective measures (such as starting the cooling equipment in the transformer room 110, adjusting the humidity in the transformer room 110, etc.).

[0041] Optionally, the annular track 1 includes a track body 11 and a crossbeam 12 . The track body 11 is configured as a rectangular structure matching the transformer chamber 110 , and the crossbeam 12 is connected to two opposite sides of the track body 11 .

[0042] In this optional embodiment, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cross section (XY plane) of the transformer chamber 110 is rectangular. By setting the track body 11 to a rectangle matching the transformer chamber 110, the track body 11 can be as close to the inner wall of the transformer chamber 110 as possible, so that the track body 11 does not occupy the internal space of the transformer chamber 110. The crossbeam 12 can be integrally formed on two opposite sides of the track body 11, and the two ends of the crossbeam 12 can also be connected to the two opposite sides of the track body 11 by screws or welded, thereby improving the structural strength of the track body 11.

[0044] In this optional embodiment, combined with Figure 1 and Figure 4 As shown, there are four protrusions 13 in total, and the four protrusions 13 are respectively arranged at the four corners of the track body 11, and the protrusions 13 are located on the outside of the track body 11, that is, the protrusions 13 are arranged on the side of the track body 11 facing the inner wall of the transformer chamber 110. In this way, when the electric trolley 24 moves along the track of the circular track 1, the first slide bar 3 will not block the shooting picture of the monitoring camera 21, and the bottom end of the first slide bar 3 can be connected to the bottom of the inner wall of the transformer chamber 110. The setting of the first slide bar 3 can play a role in limiting and guiding the circular track 1 when it moves vertically, thereby ensuring the stability of the circular track 1 when it moves vertically.

[0045] Furthermore, the intelligent monitoring device of the wind turbine box transformer also includes a driving mechanism 4, which is connected to the circular track 1 to drive the circular track 1 to move vertically. The driving mechanism 4 drives the circular track 1 to move vertically downward or vertically upward.
