Description

Technical Field

[0001] This utility model relates to the field of transformers, specifically a comprehensive monitoring device for transformer operating status. Background Technology

[0002] In the operation of power systems, transformers are the core equipment for power transmission and distribution, and real-time monitoring of their operating status is crucial to ensuring the safety and stability of the power grid.

[0003] Existing monitoring equipment lacks remote visualization of external conditions, and most rely on manual inspections to check for abnormalities such as oil leaks and discharge marks on the transformer's exterior. This is not only time-consuming and labor-intensive, but also has problems such as long inspection cycles and safety hazards associated with working at heights. Especially in remote substations or in severe weather conditions, the timeliness and accuracy of manual inspections are difficult to guarantee. Failure to detect external defects such as bushing cracks and blocked heat sinks in time may lead to the escalation of faults. Therefore, it is necessary to design a comprehensive monitoring device for the transformer's operating status to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a comprehensive monitoring device for transformer operating status to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive monitoring device for transformer operating status, comprising a transformer body, a housing installed on the top of the transformer body, a monitoring component disposed inside the housing, an annular rotating plate rotatably mounted on the lower outer side of the transformer body, a plurality of teeth mounted on the outer side of the annular rotating plate, and a drive component for driving the teeth to rotate installed on one side of the transformer body.

[0006] A control box is mounted on the top surface of the annular rotating plate. A second motor is fixedly mounted on the top surface of the control box. A swing rod is fixedly mounted on the output end of the second motor. A monitoring camera is fixedly mounted on one end of the swing rod.

[0007] Preferably, the control box contains a controller, a wireless transmission module, and a power supply battery.

[0008] Preferably, a protective canopy is fixedly installed on the side of the transformer body.

[0009] Preferably, the monitoring component includes a vibration sensor, a temperature sensor, and a control board. The control board is fixedly installed inside the housing, the vibration sensor is fixedly installed on the top of the transformer body, and the temperature sensor is fixedly installed inside the transformer body. Both the vibration sensor and the temperature sensor are electrically connected to the control board.

[0010] Preferably, the drive assembly includes a mounting plate, which is fixedly mounted on one side of the transformer body. A first motor is fixedly mounted on the top surface of the mounting plate, and a gear is fixedly mounted on the output end of the first motor, with the gear meshing with the teeth.

[0011] Preferably, the teeth are distributed in a ring at equal intervals on the outer side of the annular rotating plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This transformer operation status comprehensive monitoring equipment monitors the vibration status of the transformer body through vibration sensors and the oil temperature status of the transformer body through temperature sensors. The vibration and temperature sensors transmit the data to the control board. The microcontroller and wireless transmission module integrated on the control board can send the vibration and oil temperature data to the control room for online real-time monitoring, thereby assessing the oil temperature and changes in key parameters such as the vibration amplitude, frequency, and phase of the windings and core.

[0014] 2. This comprehensive transformer operation status monitoring equipment uses a monitoring camera to capture images of the outside of the transformer body. The images are transmitted in real time to the control room via a wireless transmission module inside the control box. The control board can control the rotation of the first motor, which in turn drives the gears to rotate. The gears, through their teeth, drive the annular rotating plate to rotate, thereby changing the positions of the control box, the second motor, the swing arm, and the monitoring camera. The monitoring camera is moved to different positions outside the transformer body to capture images, facilitating remote inspection by safety personnel in the control room to check for abnormalities such as oil leaks and discharge marks on the transformer's exterior, thus improving the convenience of operation status inspection.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a comprehensive monitoring device for transformer operation status, including a transformer body 1, a housing 2 installed on the top of the transformer body 1, a monitoring component installed inside the housing 2, an annular rotating plate 9 rotatably installed on the lower outer side of the transformer body 1, a plurality of teeth 10 installed on the outer side of the annular rotating plate 9, and a drive component for driving the teeth 10 to rotate installed on one side of the transformer body 1.

[0022] A control box 14 is installed on the top surface of the annular rotating plate 9. A second motor 15 is fixedly installed on the top surface of the control box 14. A swing rod 16 is fixedly installed at the output end of the second motor 15. A monitoring camera 17 is fixedly installed at one end of the swing rod 16.

[0023] Specifically, the monitoring components can monitor various parameters inside the transformer body 1 to assess its internal operating status, while the monitoring camera 17 can remotely view the external condition of the transformer body 1, facilitating the timely detection of external defects such as bushing cracks and heat sink blockages.

[0024] The control box 14 contains a controller, a wireless transmission module, and a power supply battery. The controller can control the rotation angle of the second motor 15, thereby changing the position of the monitoring camera 17. The power supply battery can supply power to the monitoring camera 17 and the second motor 15. The wireless transmission module is used to transmit the images captured by the monitoring camera 17 to the control room.

[0025] Among them, a protective canopy 4 is fixedly installed on the side of the transformer body 1, which shields the monitoring camera 17, thereby protecting the monitoring camera 17 when it is not in use.

[0026] The monitoring components include a vibration sensor 6, a temperature sensor 7, and a control board 5. The control board 5 is fixedly installed inside the housing 2, the vibration sensor 6 is fixedly installed on the top of the transformer body 1, and the temperature sensor 7 is fixedly installed inside the transformer body 1. Both the vibration sensor 6 and the temperature sensor 7 are electrically connected to the control board 5. The vibration sensor 6 monitors the vibration state of the transformer body 1, and the temperature sensor 7 monitors the oil temperature state of the transformer body 1. The vibration sensor 6 and the temperature sensor 7 transmit the data to the control board 5. The microcontroller and wireless transmission module integrated on the surface of the control board 5 can send the vibration and oil temperature data to the control room for online real-time monitoring.

[0027] The drive assembly includes a mounting plate 11, which is fixedly installed on one side of the transformer body 1. A first motor 12 is fixedly installed on the top surface of the mounting plate 11. A gear 13 is fixedly installed at the output end of the first motor 12. The gear 13 meshes with teeth 10. The teeth 10 are distributed in a ring at equal intervals on the outside of the annular rotating plate 9. The first motor 12 is controlled to rotate, thereby driving the gear 13 to rotate. The gear 13 drives the annular rotating plate 9 to rotate through the teeth 10.

[0028] Working principle: This utility model is a comprehensive monitoring device for transformer operation status. During use, the vibration sensor 6 monitors the vibration status of the transformer body 1, and the temperature sensor 7 monitors the oil temperature status of the transformer body 1. The vibration sensor 6 and the temperature sensor 7 transmit the data to the control board 5. The single-chip microcomputer and wireless transmission module integrated on the surface of the control board 5 can send the vibration and oil temperature data to the control room for online real-time monitoring, thereby evaluating the oil temperature and the changes in key parameters such as the vibration amplitude, frequency, and phase of the windings and core.

[0029] During external inspections, the controller inside the control box 14 can control the second motor 15 to rotate, thereby causing the swing arm 16 and the monitoring camera 17 to rotate 180 degrees. At this time, the monitoring camera 17 is shooting towards the outside of the transformer body 1, and the image is transmitted to the control room in real time through the wireless transmission module inside the control box 14. The control board 5 can be used to control the first motor 12 to rotate, thereby driving the gear 13 to rotate. The gear 13 drives the annular rotating plate 9 to rotate through the teeth 10, thereby changing the position of the control box 14, the second motor 15, the swing arm 16, and the monitoring camera 17. The monitoring camera 17 is moved to different positions outside the transformer body 1 to shoot, which facilitates remote inspection by the safety inspectors in the control room to check for abnormalities such as oil leakage and discharge marks on the outside of the transformer, improving the convenience of the operation status inspection. After the inspection is completed, the annular rotating plate 9 rotates to the position where the control box 14 faces the underside of the protective shed 4. At this time, the second motor 15 drives the swing arm 16 and the monitoring camera 17 to rotate to the reset position, thereby retracting the monitoring camera 17 under the protective shed 4, effectively protecting the monitoring camera 17 when not in use.
