[0002] A transformer box is a box-like structure in a power system that transforms, concentrates, and distributes electrical energy in terms of voltage and current. To ensure power quality and equipment safety, transformer boxes also require voltage regulation, current control, and protection for transmission and distribution lines and major electrical equipment.
[0003] Most existing transformer boxes are not equipped with modules that can monitor their internal conditions in real time. This makes it impossible to monitor the operating status of various lines and electronic equipment inside the transformer box in real time, to deal with the high temperature generated by the transformer box due to long-term operation in a timely manner, and to provide timely warnings and diagnoses of circuit or equipment faults. As a result, power personnel cannot know the operating status of the equipment inside the transformer box in a timely manner, thus prolonging the response time for transformer box maintenance and causing unnecessary losses.

[0021] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The embodiments are described in detail below.
[0022] This embodiment provides a real-time early warning and diagnostic device for substations, as shown in the attached document. Figure 1-7 As shown, the transformer box includes a main body 1 and a top 2. Sensor modules for monitoring the internal conditions are installed on both sides of the main body 1. These sensor modules include temperature sensors 6 and humidity sensors 7. Several temperature sensors 6 are evenly divided into two groups, each group fixedly installed in a rectangular array on both sides of the main body 1. Multiple temperature sensors 6 within each group are fixedly installed on the top, middle, and bottom sides of the main body 1, enabling real-time temperature monitoring of different parts within the main body 1, thus improving the accuracy of the monitoring range. Two humidity sensors 7 are fixedly installed on both sides of the main body 1, enabling real-time monitoring of the air humidity inside the main body 1 to prevent circuit damage caused by excessively high humidity.
[0023] The top of both sides of the transformer box body 1 is equipped with an adjustable heat dissipation mechanism for targeted heat dissipation of the interior of the transformer box body 1. The adjustable heat dissipation mechanism includes a heat dissipation fan 8, a first spur gear 9, a first rack 10, and a first electric push rod 11. Both sides of the transformer box body 1 are provided with mounting slots 12 for installing the adjustable heat dissipation mechanism. The first spur gear 9 is fixedly connected to the middle of the side of the heat dissipation fan 8, and the heat dissipation fan 8 is rotatably connected to the mounting slot 12 on the side of the transformer box body 1. The first rack 10 is vertically fixedly connected to the bottom of the movable rod of the first electric push rod 11 and meshes with the first spur gear 9. The fixed rod of the first electric push rod 11 is vertically fixedly installed on the inner side wall of the transformer box body 1. The extension and retraction of the movable rod of the first electric push rod 11 can drive the first spur gear 9 to rotate through the first rack 10, thereby driving the heat dissipation fan 8 to rotate. This facilitates adjustment of the air blowing angle of the heat dissipation fan 8, so as to correspond to different parts inside the transformer box body 1 for targeted and efficient heat dissipation.
[0024] Protective mesh plates 18 are hinged to both sides of the transformer box body 1, corresponding to the adjustable heat dissipation mechanism. The protective mesh plates 18 are set outside the mounting groove 12 and correspond to the adjustable heat dissipation mechanism. Ventilation slots for ventilation are opened on the side of the protective mesh plates 18, which can ensure that the heat dissipation fan 8 has a good ventilation effect and prevent some debris from entering the transformer box body 1. When the heat dissipation fan 8 rotates, it will push the protective mesh plates 18 to move outward. The protective mesh plates 18 will not affect the movement of the heat dissipation fan 8.
[0025] The top of the enclosure 2 is fixedly connected to the top of the transformer box body 1, and warning lights 3 are fixedly installed on both sides of the top of the enclosure 2. When the temperature sensor 6, humidity sensor 7, or monitoring probe 17 detects that the temperature or humidity inside the transformer box body 1 is too high, or that the lines or equipment are damaged, the warning lights 3 can be controlled to flash through the external control unit to serve as a warning and to allow power personnel to be notified of the alarm situation in a timely manner. A hanger 4 is fixedly connected to the middle of the inner top wall of the enclosure 2, and a mounting bracket 5 is fixedly connected to the bottom of the hanger 4. The hanger 4 and the mounting bracket 5 are equipped with a cyclic monitoring mechanism for real-time monitoring of the entire interior of the transformer box body 1. The ring monitoring mechanism includes a second electric push rod 13, a second rack 14, a second spur gear 15, a connecting frame 16, and a monitoring probe 17. The second rack 14 is vertically fixed to the bottom end of the movable rod of the second electric push rod 13 and passes through the middle of the upper surface of the mounting frame 5. The fixed rod of the second electric push rod 13 is vertically fixed to the middle of the upper surface of the hanger 4. There are two second spur gears 15, and both second spur gears 15 are rotatably connected to both sides inside the mounting frame 5. The second rack 14 is vertically inserted between the two second spur gears 15 and meshes with them. The bottoms of the two second spur gears 15 are fixedly connected to... A connecting frame 16 is connected, and a monitoring probe 17 is fixedly installed at the bottom of the connecting frame 16. The second electric push rod 13 drives the second rack 14 to move up and down cyclically, which in turn drives the second spur gears 15 on both sides to rotate synchronously in opposite directions. This causes the monitoring probe 17 below to rotate cyclically within a 90-degree range to monitor various parts inside the transformer box body 1. The initial state of the two monitoring probes 17 is vertically downward, and the movable rod of the second electric push rod 13 is in a fully retracted state. When the second electric push rod 13 moves and drives the second rack 14 downward, it can drive the second spur gear 15 on the left side to rotate clockwise. The clockwise rotation and the counterclockwise rotation of the second spur gear 15 on the right cause the two monitoring probes 17 to rotate to the sides respectively. When the movable rod of the second electric push rod 13 extends to its maximum distance, the two monitoring probes 17 are in a horizontal state and are symmetrically arranged with the vertical center line of the mounting bracket 5 as the axis of symmetry. Then the second electric push rod 13 drives the second rack 14 to move upward, thereby driving the two monitoring probes 17 to move closer to each other again through the second spur gears 15 on both sides until the monitoring probes 17 are vertically downward, forming a cycle. Then the above steps are continued to achieve uniform speed circulation of the monitoring probes 17 to perform early warning monitoring inside the transformer box body 1.
[0026] The monitoring probe 17 consists of a visualization camera 1701 and an infrared temperature sensor 1702. Both the visualization camera 1701 and the infrared temperature sensor 1702 are oriented downwards and can rotate with the second spur gear 15. The visualization camera 1701 can perform visual monitoring of the entire interior of the transformer box 1, allowing for direct observation of the lines and equipment inside the transformer box 1. The infrared temperature sensor 1702 can cyclically monitor the temperature of its corresponding parts inside the transformer box 1. The two work together to further improve the accuracy of the monitoring.
[0027] Warning light 3, temperature sensor 6, humidity sensor 7, cooling fan 8, first electric push rod 11, second electric push rod 13, visual camera 1701, and infrared temperature sensor 1702 are all electrically connected to an external control unit. The sensing thresholds of temperature sensor 6, humidity sensor 7, and infrared temperature sensor 1702 are set. Exceeding the set threshold indicates an abnormality that may affect the normal operation of the equipment. When the real-time temperature or humidity detected by temperature sensor 6, humidity sensor 7, and infrared temperature sensor 1702 exceeds the set threshold, the control unit controls warning light 3 to sound an alarm. At the same time, the alarm information can be synchronously transmitted to the terminal device so that monitoring personnel can be informed of the alarm situation in a timely manner and take appropriate action.
[0028] In summary, the usage steps of this real-time early warning and diagnostic device for substations are as follows:
[0029] 1. The second electric push rod 13 drives the second rack 14 to move up and down in a cycle. The second rack 14 can drive the second spur gears 15 on both sides to rotate synchronously in opposite directions, thereby driving the monitoring probe 17 below to rotate in a 90-degree range to monitor various parts inside the transformer box body 1.
[0030] 2. Temperature sensors 6 on both sides of the transformer box body 1 monitor the temperature of the corresponding parts in real time. When the temperature sensor 6 of a certain part detects that the temperature is too high, the control unit can control the moving rod of the first electric push rod 11 to move, thereby driving the cooling fan 8 to rotate through the first rack 10 and the first spur gear 9, so that the cooling fan 8 on both sides is directed towards the area with excessive temperature.
[0031] 3. Then run cooling fan 8 to provide targeted and efficient cooling to areas with excessively high temperatures, which can quickly reduce the temperature and prevent damage caused by continuously high temperatures.
[0032] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
