[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil and the iron core. Its main functions are: voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. Transformers can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, corner transformers, high current transformers, excitation transformers, etc.

[0038] In addition, sound-absorbing cotton is installed inside the noise reduction protective shell 3, which can further improve the sound insulation of the dry-type transformer body 1. The monitoring device 6 is composed of a high-definition camera and a temperature and humidity sensor, which can not only perform all-round and multi-angle monitoring around the transformer to ensure no dead angle coverage and timely discover abnormal conditions outside the transformer, but also adopts advanced technologies such as high-definition cameras to clearly capture details of the transformer appearance, such as cracks, rust, oil leakage, etc., to improve the accuracy of monitoring, and further monitor the dry-type transformer body 1 using a temperature and humidity sensor.

[0039] It should be noted that a remote control module is installed in the monitoring device 6 to support remote management. The monitoring device 6 supports remote access and control. The operation and maintenance personnel can remotely view the real-time images and data of the transformer through the network to achieve remote monitoring and management.

Through data analysis, the operating trends and potential problems of the dry-type transformer body 1 can be discovered in a timely manner, providing a scientific basis for preventive maintenance.

[0040] In order to achieve efficient monitoring of the dry-type transformer body 1, in this embodiment, as Figure 2 - Figure 6As shown, a walking mechanism 5 for moving the monitoring device 6 and a bottom guide seat 4 for cooperating with the monitoring device 6 are arranged in the noise reduction protective shell 3, the walking mechanism 5 includes a base 501, a driving structure 502 installed on the upper surface of the base 501 and a top guide seat 503 arranged above the bottom guide seat 4, the driving structure 502 includes a driving motor 5021 installed on the upper surface of the base 501 by bolts, a rotating shaft 5022 fixedly installed on the output shaft of the driving motor 5021, a connecting shaft 5023 fixedly installed on the other end of the rotating shaft 5022, and a walking wheel 5024 rotatably installed on the other end of the connecting shaft 5023; wherein, the number of the rotating shaft 5022 and the walking wheel 5024 are both two, and the two rotating shafts 5022 are provided with a transmission structure, a second guide groove 504 for cooperating with the walking wheel 5024 is opened in the top guide seat 503, and the walking wheel 5024 extends into the second guide groove 504 and is rollingly connected with its inner wall to realize the circular motion of the monitoring device 6.

[0041] When this embodiment is in use, the circular motion of the walking mechanism 5 enables the monitoring device 6 to rotate around the dry-type transformer body 1, thereby performing all-round and multi-angle monitoring of the dry-type transformer body 1, ensuring coverage without blind spots, timely discovering abnormal conditions outside the dry-type transformer body 1, realizing unmanned automated inspections, and reducing the workload of operation and maintenance personnel. In addition, the monitoring device 6 that can walk around can replace manual inspections, reducing the safety risks of staff, thereby achieving the advantages of high efficiency and convenience.

[0042] Specifically, Figure 3 and Figure 4 As shown, the bottom guide seat 4 and the top guide seat 503 are both provided with a through hole 505 connected to the outside, and the dry-type transformer body 1 passes through the bottom guide seat 4 through the through hole 505. The bottom transmission structure is composed of two first synchronous wheels 5025, and the transmission connection between the two first synchronous wheels 5025 is a first synchronous belt 5026. The two first synchronous wheels 5025 are respectively fixedly installed on the outside of the two connecting shafts 5023. The driving motor 5021 is started to transmit through the connecting shaft 5023, so that the walking wheel 5024 rotates to drive the base 501 to move in a circle around the bottom guide seat 4.

[0043] It should be noted that the bottom guide seat 4 and the top guide seat 503 are annular in shape, and a first guide groove 42 is provided inside the bottom guide seat 4, and a slider 5011 is fixedly installed on the outside of the base 501 to slide with the first guide groove 42. In order to improve the moving effect, an anti-skid pad is sleeved on the outer surface of the running wheel 5024 to enhance the rolling connection with the second guide groove 504, and a weight block is provided on the slider 5011 to prevent the end of the base 501 from being subjected to excessive force, and a running wheel 5024 can also be added to the slider 5011, which is connected to the connecting shaft 5023 by a synchronous belt.

[0044] The bottom of the bottom guide seat 4 is welded with a support leg 41 fixed to the upper surface of the shock-absorbing pad 2. The number of the support legs 41 is at least three, so as to achieve stable support for the bottom guide seat 4. Two symmetrically arranged support seats 5027 are welded and installed on the upper surface of the base 501, and the two rotating shafts 5022 and the connecting shaft 5023 are respectively connected to the bearings of the two support seats 5027.

[0045] In order to further improve the monitoring effect of the monitoring device 6, in this embodiment, Figure 2 , Figure 5 - Figure 8 As shown, a reciprocating mechanism 7 for adjusting the monitoring device 6 in linkage with the walking mechanism 5 is provided on the upper surface of the base 501, and the reciprocating mechanism 7 includes a synchronous shaft 701 and a telescopic structure 704 provided outside the base 501, a rotating disk 702 fixedly installed at one end of the synchronous shaft 701, a connecting rod 703 provided outside the rotating disk 702 and connected to the telescopic structure 704, and a synchronous structure 706 installed at the other end of the synchronous shaft 701 and connected to the rotating shaft 5022.

[0046] When this embodiment is in use, the monitoring device 6 is further improved by performing circular motion and then adjusting the reciprocating mechanism 7 up and down to further improve the monitoring of the dry-type transformer body 1 by the monitoring device 6. In addition, the linkage between the walking mechanism 5 and the reciprocating mechanism 7 can enhance the flexibility and comprehensiveness of monitoring. For example, through the circular motion of the walking mechanism 5, the monitoring device 6 can perform all-round monitoring around the dry-type transformer body 1 to ensure coverage without blind spots. At the same time, the up and down adjustment function enables the monitoring device 6 to perform fine monitoring at different heights and angles of the transformer and capture more details; different monitoring tasks may require attention to different parts or angles of the dry-type transformer body 1. This design enables the monitoring device 6 to flexibly adjust the monitoring position and angle to meet diverse monitoring needs.

[0047] In addition, the up and down adjustment function enables the monitoring device 6 to accurately locate the parts that need to be monitored, such as the air inlet and outlet of the dry-type transformer body 1, the wiring terminals and other key positions, thereby improving the accuracy of monitoring. Through automated adjustment and monitoring, the repetitive labor of manual inspections is reduced. The linkage use of the walking mechanism 5 and the reciprocating mechanism 7 can improve the monitoring efficiency and accuracy. At the same time, through automated adjustment and monitoring, the repetitive labor of manual inspections is reduced and the monitoring efficiency is improved. At the same time, automated monitoring can also achieve continuous and uninterrupted monitoring and timely discover potential problems.

[0048] Specifically, the telescopic structure 704 is composed of a telescopic sleeve 7041 and a telescopic rod 7042 that are telescopically connected. A buffer spring 705 is arranged outside the telescopic rod 7042. A mounting platform 707 is welded on the side wall of the base 501, and the bottom ends of the telescopic rod 7042 and the buffer spring 705 are both mounted on the upper surface of the mounting platform 707. By installing the buffer spring 705 outside the telescopic rod 7042, the telescopic structure 704 can be buffered when it is telescoped, and the reciprocating adjustment of the reciprocating mechanism 7 on the monitoring device 6 can be improved, so that it can be used stably. Among them, an abutment block 7045 connected to the top of the buffer spring 705 is welded on the bottom end of the telescopic sleeve 7041, and a mounting sleeve 7043 is inserted and installed on the outer surface of the telescopic sleeve 7041. The abutment block 7045 is a circular rubber pad.

[0049] In order to ensure the stable expansion and contraction of the telescopic structure 704, Figure 7 and Figure 8 As shown, two symmetrically arranged limit blocks 7046 are fixedly mounted on the outer surface of the top of the telescopic rod 7042, the telescopic sleeve 7041 is hollow inside, and a limit groove 7047 is provided inside the telescopic sleeve 7041 to slide with the two limit blocks 7046. A mounting plate 7044 for mounting the monitoring device 6 is welded to the top of the telescopic sleeve 7041, and the monitoring device 6 is mounted on the upper surface of the mounting plate 7044 by bolts. The telescopic rod 7042 is limited and guided by the sliding cooperation between the limit blocks 7046 and the limit grooves 7047, thereby achieving linear displacement.

[0050] In this embodiment, a vertical seat 708 is welded on the upper surface of the base 501, and the synchronization shaft 701 is connected to the vertical seat 708 bearing to ensure stable rotation of the synchronization shaft 701 and achieve stable adjustment. Both ends of the connecting rod 703 are rotatably installed with shaft rods, and the two shaft rods are respectively connected and fixed to the turntable 702 and the mounting sleeve 7043.

[0051] like Figure 1 - Figure 8 As shown, the principle of the noise reduction dry-type transformer provided in this embodiment is as follows:

[0052] When in use, the drive motor 5021 is started and transmitted through the connecting shaft 5023, so that the walking wheel 5024 rotates to drive the base 501 to move in a circle around the bottom guide seat 4. At the same time, the turntable 702 is driven to rotate by the transmission cooperation of the synchronous structure 706, and the telescopic structure 704 is driven to reciprocate through the connecting rod 703, so that the monitoring device 6 is adjusted up and down, so that all-round and multi-angle monitoring can be performed around the dry-type transformer body 1, ensuring coverage without blind spots, and timely discovering abnormal conditions outside the dry-type transformer body 1.
