Description

Technical Field

[0001] This utility model relates to the field of power transmission equipment technology, and in particular to a transformer monitoring device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. When the magnetic flux density of a transformer is too high, it leads to an overload on the iron core, resulting in excessive iron losses. These iron losses are mainly released as heat, causing the transformer to heat up. Simultaneously, if the contact between the transformer core windings is not tight, it will increase iron losses, further causing overheating. Furthermore, insulation damage between the silicon steel sheets in the core can also lead to increased iron losses and overheating. Therefore, abnormal overheating of a transformer can cause it to malfunction. To assess the quality of a transformer, its heating status needs to be monitored. Utility Model Content

[0022] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Depend on Figure 1-5 The transformer 1 monitoring device shown includes a monitoring box 2, which is fitted around the outside of the transformer 1. The transformer 1 is placed on the bottom of the inner cavity of the monitoring box 2. A track 3 surrounds the outside of the transformer 1, and a monitoring component is slidably connected to the track 3. The monitoring component faces the transformer 1. Two sets of lifting components are arranged around the periphery of the track 3. The lifting components include two clamps 4, which are fixedly connected to the top and bottom ends of the track 3, respectively. The clamps 4 slide in contact with a column 5. A slide rail 6 is opened on the side of the column 5. A lifter is fixedly installed in the inner cavity of the slide rail 6. The lifter is connected to the clamps 4 in a transmission manner. The column 5 is fixedly connected to the bottom of the inner cavity of the monitoring box 2. Several display screens 7 are arranged on the outer side of the monitoring box 2. The display screens 7 are electrically connected to the monitoring component.

[0024] Furthermore, the display screen 7 is a component capable of wired or wireless communication with the outside world and displaying the input information in a window. This is existing technology and will not be described in detail here.

[0025] Further optimizing the design, the lifting device includes a first telescopic component 8, with sliders 9 fixedly connected to its top and bottom ends. The two sliders 9 are fixedly connected to two clamping blocks 4. A second telescopic component 10 is fixedly connected to the bottom surface of the first telescopic component 8, and the second telescopic component 10 is fixedly connected to the bottom surface of the inner cavity of the slide rail 6. The first telescopic component 8 and the second telescopic component 10 are electric cylinders, capable of moving the clamping blocks 4 up and down through extension and retraction. This is existing technology and will not be elaborated further. The extension and retraction of the first telescopic component 8 moves the clamping blocks 4 located above, thereby raising and lowering the height of the track 3. Simultaneously, the extension and retraction of the first telescopic component 8 and the second telescopic component 10 can adjust the positions of the bottom and top ends of the track 3 in the same way, enabling data collection from the transformer 1 as needed.

[0026] The design was further optimized by creating a T-shaped groove on the side of the column 5, which is adapted to and slidably connected to the slider 9.

[0027] Further optimization of the scheme: the monitoring component includes a drive block, one end of which is fixedly connected to a temperature sensor 14, and the other end of which is fixedly connected to a motor 15. The motor 15 is a servo motor, capable of real-time communication with the controller 22 and receiving control from the controller 22. The motor 15 is driven by a gear 16, which is driven by the track 3. A groove 17 is provided on the side of the drive block away from the sensor 14. A guide post 18 is fixedly connected in the groove 17. A follower shaft 19 is sleeved on the outside of the guide post 18 and slidably connected to it. A follower wheel 20 is rotatably connected to the follower shaft 19. The follower wheel 20 is rotatably connected to the track 3. The follower wheel 20 is flexibly connected to the drive block, which can make fine adjustments and adapt to the deformation of the track 3 when the position of the track 3 changes, reducing the probability of jamming. Two springs 21 are sleeved on the outer side of the guide column 18. One end of the two springs 21 is fixedly connected to the slide groove 17, and the other end is fixedly connected to one end of the follower shaft 19. The drive block is slidably connected to the track 3. The sensor 14 is electrically connected to the controller 22. The controller 22 communicates with the display screen 7 through wireless signals. The controller 22 is a PLC controller. Through its integrated wireless communication module, it can communicate with the display screen 7 to transmit and display the signals collected by the sensor 14. This is existing technology and will not be described in detail here.

[0028] The motor 15 drives the gear 16 to rotate, enabling the detection component to move along the inner cavity of the monitoring slot 23. The sensor 14 periodically collects temperature data from the outer side of the transformer 1 it faces, which is then displayed on the screen 7. Furthermore, when the track 3 changes height, the inner diameter of the monitoring slot 23 is compressed. The follower wheel 20 supports the monitoring slot 23, and the follower shaft 19 twists and turns due to the deflection of the guide post 18, thus adapting the monitoring slot 23 to the torque generated when the track 3 changes height.

[0029] Further optimization of the design: Track 3 has a spiral structure and is made of elastic rubber or iron alloy material, making it easy to be pulled by clamping block 4 for height adjustment. A monitoring groove 23 is provided on the inner wall of track 3, which is slidably connected to the drive block. A rack is provided on the side wall of monitoring groove 23, and monitoring groove 23 is connected to gear 16 via the rack for transmission.

[0030] A further optimized design includes a drive block comprising a first guide block 11 and a second guide block 12. A flexible rubber plate 13 is hinged between the first guide block 11 and the second guide block 12. When the drive block slides within the monitoring groove 23, the arc-shaped monitoring groove 23 compresses the drive block, causing the first guide block 11 and the second guide block 12 to deflect at a relative angle to accommodate the deformation of the monitoring groove 23. A sensor 14 is fixedly connected to the first guide block 11; a sliding groove 17 is formed on the side of the second guide block 12.

[0031] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
