Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a monitoring device for an oil-immersed transformer. Background Technology

[0002] An oil-immersed transformer is a key electrical device that uses insulating oil as both a cooling and insulating medium. Its core operating principle is based on electromagnetic induction, using windings to transform voltage for efficient power transmission. The insulating oil plays a dual role: firstly, as a cooling medium, it removes heat generated by the windings and core during operation through convection circulation, ensuring controllable temperature rise; secondly, as an insulating medium, its high insulation strength effectively isolates live components, preventing breakdown accidents.

[0003] Oil-immersed transformers contain metals such as copper and aluminum, which have high market value. Criminals steal these metals from transformers to make illicit profits. Theft of transformers can cause widespread power outages in the area, affecting industrial and agricultural production, business operations, and residents' lives, resulting in significant economic losses. For example, factories may have to stop production due to power outages, data may be lost, and residents' lives will be greatly inconvenienced, such as being unable to use electrical appliances normally.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] The main objective of this invention is to provide an oil-immersed transformer monitoring device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A monitoring device for an oil-immersed transformer includes a transformer body and a mounting frame. A monitoring base is fixedly installed at the lower end of the transformer body. Two No. 1 mounting seats are fixedly installed at the left and right ends of the monitoring base. Two No. 2 mounting seats are fixedly installed at the left and right ends of the mounting frame. An adjustment device is fixedly installed at the upper end of the mounting frame. A monitoring device is fixedly installed at the front end of the adjustment device.

[0007] Preferably, the monitoring base has mounting slots on its upper left and upper right sides. Two fixing slots are formed on the lower inner wall of each of the two mounting slots. Pressure sensors are inserted into all four fixing slots, and connecting wires are fixedly installed at the lower ends of each of the four pressure sensors. Two screw holes are formed on the lower inner wall of each of the two mounting slots. When a thief begins the theft, whether by draining oil or disassembling parts of the transformer body, the weight of the transformer body will immediately decrease. The pressure sensors then transmit the weight fluctuation information to the controller. When the controller detects that the weight value is lower than a preset alarm threshold, it immediately triggers the alarm system, thereby monitoring the transformer body.

[0008] Preferably, the monitoring device includes a mounting plate, a mounting base is fixedly mounted on the front right side of the mounting plate, a camera is fixedly mounted on the front end of the mounting base, and a controller is fixedly mounted on the front left side of the mounting plate. The mounting bracket is fixed in a suitable position by the second mounting base, so that the camera can be aimed directly at the transformer body, thereby enabling real-time monitoring of the transformer body. In particular, when the pressure sensor detects weight information, the staff can immediately observe the transformer body through the camera.

[0009] Preferably, the adjustment device includes a servo motor, a threaded rod fixedly mounted on the output end of the servo motor, a slider threaded onto the outer surface of the threaded rod, a groove formed at the front end of the mounting bracket, and the servo motor fixedly mounted on the upper end of the mounting bracket. The servo motor drives the threaded rod to rotate within the groove, causing the slider on the threaded rod to slide and adjust within the groove. This not only allows the height of the camera on the mounting plate to be adjusted as needed but also facilitates lowering the mounting plate for maintenance of the camera.

[0010] Preferably, support seats are fixedly installed on the lower left and lower right sides of the transformer body, and screws are installed on the upper front and upper rear of the two support seats. The two support seats at the lower end of the transformer body are inserted into the mounting groove. At this time, the lower end of the support seat abuts against the upper end of the pressure sensor. Then, the screws on the support seats are screwed into the screw holes, thereby fixing the transformer body to the monitoring base.

[0011] Preferably, both the first mounting base and the second mounting base have a set of screw holes.

[0012] Preferably, the mounting plate is L-shaped and is fixedly mounted on the front end of the slider.

[0013] Preferably, the threaded rod is rotatably mounted in the slide groove, and the slider is slidably mounted in the slide groove.

[0014] Preferably, the screw and the screw hole are vertically aligned.

[0015] Preferably, the support base and the mounting groove are the same size and their positions are vertically corresponding.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Insert the two support seats at the lower end of the transformer body into the mounting slot. At this time, the lower end of the support seats abuts against the upper end of the pressure sensor. Then, screw the screws on the support seats into the screw holes to fix the transformer body on the monitoring base. The pressure sensor is electrically connected to the controller through the connecting wire. Once a thief begins to steal, whether by draining oil or disassembling parts of the transformer body, the weight of the transformer body will immediately decrease. The pressure sensor will then transmit the weight fluctuation information to the controller. When the controller detects that the weight value is lower than the preset alarm threshold, it will immediately trigger the alarm system to monitor the transformer body. In addition, the specifications of the monitoring base can be customized according to the structural characteristics of different transformer models, which ensures both installation compatibility and the accuracy of weight measurement.

[0017] 2. The mounting bracket is fixed in a suitable position by mounting base No. 2, so that the camera can be aimed directly at the transformer body, thereby enabling real-time monitoring of the transformer body. In particular, when the pressure sensor detects weight information, the staff can immediately observe the transformer body through the camera.

[0018] 3. After the mounting bracket is fixed, the servo motor drives the threaded rod to rotate in the slide groove. At this time, the slider on the threaded rod slides and adjusts in the slide groove. This not only allows the height of the camera on the mounting plate to be adjusted as needed, but also makes it easier to lower the mounting plate so that staff can inspect the camera.

[0024] like Figures 1-5 As shown, an oil-immersed transformer monitoring device includes a transformer body 1 and a mounting frame 5. A monitoring base 2 is fixedly installed at the lower end of the transformer body 1. Two No. 1 mounting seats 6 are fixedly installed at the left and right ends of the monitoring base 2. Two No. 2 mounting seats 7 are fixedly installed at the left and right ends of the mounting frame 5. An adjustment device 4 is fixedly installed at the upper end of the mounting frame 5. A monitoring device 3 is fixedly installed at the front end of the adjustment device 4. A set of screw holes is opened on both the No. 1 mounting seat 6 and the No. 2 mounting seat 7.

[0025] The monitoring base 2 has mounting slots 20 on its upper left and upper right sides. Two fixing slots 23 are formed on the lower inner wall of each mounting slot 20. Pressure sensors 21 are inserted into each of the four fixing slots 23. Connecting wires 22 are fixedly installed at the lower ends of each of the four pressure sensors 21. Two screw holes 24 are formed on the lower inner wall of each mounting slot 20. When a thief begins the theft, whether by draining oil or disassembling parts of the transformer body 1, the weight of the transformer body 1 will immediately decrease. The pressure sensors 21 will then transmit the weight fluctuation information to the controller 33. When the controller 33 detects that the weight value is lower than the preset alarm threshold, it immediately triggers the alarm system, thereby monitoring the transformer body 1.

[0026] The monitoring device 3 includes a mounting plate 30, a mounting base 31 fixedly mounted on the front right side of the mounting plate 30, a camera 32 fixedly mounted on the front end of the mounting base 31, and a controller 33 fixedly mounted on the front left side of the mounting plate 30. The mounting bracket 5 is fixed in a suitable position by the second mounting base 7, so that the camera 32 can be aimed directly at the transformer body 1, thereby enabling real-time monitoring of the transformer body 1. In particular, when the pressure sensor 21 detects weight information, the staff can immediately observe the transformer body 1 through the camera 32.

[0027] The adjustment device 4 includes a servo motor 40, with a threaded rod 41 fixedly mounted on the output end of the servo motor 40. A slider 42 is threaded onto the outer surface of the threaded rod 41. A groove 43 is opened at the front end of the mounting bracket 5, and the servo motor 40 is fixedly mounted on the upper end of the mounting bracket 5. The mounting plate 30 is L-shaped and fixedly mounted on the front end of the slider 42. The threaded rod 41 is rotatably mounted in the groove 43, and the slider 42 is slidably mounted in the groove 43. The servo motor 40 drives the threaded rod 41 to rotate in the groove 43, at which time the slider 42 on the threaded rod 41 slides and adjusts in the groove 43. This not only allows the height of the camera 32 on the mounting plate 30 to be adjusted as needed, but also facilitates the lowering of the mounting plate 30, allowing personnel to inspect the camera 32.

[0028] Support seats 50 are fixedly installed on the lower left and lower right sides of the transformer body 1. Screws 51 are installed on the upper front and upper rear of the two support seats 50. The screws 51 are vertically aligned with the screw holes 24. The support seats 50 and the mounting groove 20 are the same size and vertically aligned. The two support seats 50 at the lower end of the transformer body 1 are inserted into the mounting groove 20. At this time, the lower end of the support seat 50 abuts against the upper end of the pressure sensor 21. Then, the screws 51 on the support seats 50 are screwed into the screw holes 24, thereby fixing the transformer body 1 to the monitoring base 2. The electrical equipment of this utility model is all existing technology. The electrical equipment can operate normally during trial operation. The controller 33 needs to be connected to an external power source when in use, and the controller 33 and the electrical equipment in this utility model are electrically connected.

[0029] It should be noted that this utility model is a monitoring device for an oil-immersed transformer. First, the mounting bracket 5 is fixed in a suitable position by the second mounting base 7, so that the camera 32 can be aligned with the transformer body 1, thereby enabling real-time monitoring of the transformer body 1. In particular, when the pressure sensor 21 detects weight information, the staff can immediately observe the transformer body 1 through the camera 32. After the mounting bracket 5 is fixed, the servo motor 40 drives the threaded rod 41 to rotate in the slide groove 43. At this time, the slider 42 on the threaded rod 41 slides and adjusts in the slide groove 43, which not only allows the height of the camera 32 on the mounting plate 30 to be adjusted as needed, but also facilitates the lowering of the mounting plate 30, allowing the staff to monitor the camera. After inspecting the camera 32, the two support seats 50 at the lower end of the transformer body 1 are inserted into the mounting slot 20. At this time, the lower end of the support seat 50 abuts against the upper end of the pressure sensor 21. Then, the screws 51 on the support seat 50 are screwed into the screw holes 24, thereby fixing the transformer body 1 on the monitoring base 2. The pressure sensor 21 is electrically connected to the controller 33 through the connecting wire 22. Once a thief starts stealing, whether it is draining oil or disassembling parts of the transformer body 1, the weight of the transformer body 1 will immediately decrease. The pressure sensor 21 will then transmit the weight fluctuation information to the controller 33. When the controller 33 detects that the weight value is lower than the preset alarm threshold, it immediately triggers the alarm system to monitor the transformer body 1.
