[0002] In the power industry, dry-type transformers are important electrical equipment. The stability and safety of their performance are crucial to the normal operation of the power system. In order to ensure the quality and reliability of dry-type transformers, it is essential to conduct various tests and inspections on them regularly. Among them, insulation resistance test is one of the key steps to evaluate the insulation performance of dry-type transformers. When conducting insulation resistance test, the cleanliness of the terminal has a direct impact on the accuracy and reliability of the test results.

[0003] Traditional dry-type transformer test devices mainly rely on manual cleaning of the terminal blocks when conducting insulation resistance tests. Operators need to use brushes, cloths and other tools to manually remove dirt, dust and other impurities on the outer wall of the terminal blocks. However, this manual cleaning method has many shortcomings. First, manual cleaning is inefficient, time-consuming and labor-intensive, and the cleaning effect is greatly affected by the operator's experience and skill level. Second, manual cleaning is difficult to ensure uniformity and thoroughness of cleaning. There may be dead corners or residues on the surface of the terminal blocks that cannot be cleaned, thereby affecting the accuracy of the insulation resistance test.

Compared with traditional manual or static cleaning methods, this vibration cleaning method can more effectively remove stains, dust and other impurities, thereby improving the cleaning efficiency. The addition of vibration enables the bristles to better adapt to the shape and contour of the surface being cleaned, improving the uniformity and thoroughness of cleaning. At the same time, due to the enhanced friction generated by the vibration, stains and dust are more easily removed by the bristles, thereby improving the cleaning effect.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Combination Figure 1-Figure 9 As shown, the present invention provides a technical solution: a dry-type transformer test device, comprising a workbench 1 and a transformer body 2, wherein the transformer body 2 is installed on the workbench 1, and the structure of the transformer body 2 includes a terminal 3 for connecting an external circuit, and a test assembly 4 for performing various tests on the transformer body 2 is specially designed on one side of the workbench 1;

[0029] The design of the test assembly 4 includes a moving seat 41 that can be slidably installed on the workbench 1. The outer end of the moving seat 41 is fixedly installed with a first cylinder 42. The output end of the first cylinder 42 is connected to a detection head 43. One end of the detection head 43 is designed with a sleeve 44 that is compatible with the terminal 3 of the transformer body 2. An insulation resistance tester body 432 is also fixedly installed on the workbench 1. The two ends of the insulation resistance tester body 432 are respectively connected to an L-end wire 433 and an E-end wire 434. The other end of the L-end wire 433 is connected to the The detection head 43 is connected, and the other end of the E-end wire 434 is grounded. When the transformer body 2 needs to be tested, the detection head 43 and the bushing 44 can be driven to move toward the transformer body 2 by starting the first cylinder 42, so that the bushing 44 can be sleeved on the wiring terminal 3, and ensure that the detection head 43 is correctly connected to the wiring terminal 3. Then, the E-end wire 434 is connected to the ground, and the transformer body 2 is tested by starting the insulation resistance tester body 432, and the insulation resistance value is recorded;

[0030] In order to further improve the flexibility and accuracy of the test, an adjustment motor 436 is also fixedly connected to one end of the workbench 1, and a screw rod 435 is connected to the output end of the adjustment motor 436. The screw rod 435 is rotatably mounted on the workbench 1, and the moving seat 41 is connected to the screw rod 435 by a threaded connection. The adjustment motor 436 is a forward and reverse motor. By starting the adjustment motor 436, the screw rod 435 can be driven to rotate synchronously, and then the moving seat 41 can be moved synchronously, thereby realizing the synchronous movement of the detection head 43 and the bushing 44, so that the detection head 43 can detect and process different terminals 3 of the transformer body 2;

[0031] A fixed disk 45 is fixedly connected to one end of the movable seat 41 close to the transformer body 2, and a gear ring 46 is rotatably connected to the fixed disk 45. A driving gear 421 is meshedly connected to both sides of the gear ring 46. A servo motor 420 fixedly installed on the fixed disk 45 is provided on one side of the driving gear 421. Mounting grooves 419 are provided on both sides of the surface of the gear ring 46. A rotating plate 47 is rotatably connected to the mounting groove 419. An arc plate 48 is fixedly connected to one end of the rotating plate 47 close to the transformer body 2. A brush 49 is provided on the inner side end of the arc plate 48. By starting the servo motor 420, the driving gear 421 can be driven to rotate synchronously, and then the driving gear 421 drives the meshing gear ring 46 to rotate synchronously. The rotation of the gear ring 46 drives the rotating plate 47, the arc plate 48 and the brush 49 to rotate synchronously. The arc plate 48 and the brush 49 rotate synchronously, and the outer wall of the terminal block 3 can be cleaned. By cleaning the dirt, dust or other impurities on the outer wall of the terminal block 3, it can be ensured that the insulation resistance tester body 432 can more accurately inspect and measure the terminal block 3, which helps to find potential connection problems, corrosion or wear, etc., so as to avoid misjudgment or missed detection, and avoid dirt and impurities interfering with the reading or judgment of the detection equipment, resulting in deviations in the detection results. By cleaning, these interference factors can be eliminated, and the accuracy and reliability of the detection results can be improved. The cleaned terminal block 3 is more easily identified and measured by the insulation resistance tester body 432, thereby reducing manual intervention and debugging time in the detection process, which helps to improve detection efficiency and shorten the detection cycle;

[0032] The outer end of the fixed plate 45 is fixedly connected to a sliding frame 410, and a second cylinder 411 is fixedly installed on the sliding frame 410. The output end of the second cylinder 411 is fixedly connected to an adjustment plate 412, and the adjustment plate 412 is slidably installed on the rotating plate 47. Both sides of the rotating plate 47 are fixedly connected to arc rods 413. By starting the second cylinder 411, the adjustment plate 412 can be driven to move outward, thereby driving the rotating plate 47 to rotate, and then the rotating plate 47 drives the arc plate 48 to rotate inward, so that the arc plate 48 is close to the side of the terminal 3;

[0033] A dust suction hole is provided at the inner end of the arc plate 48, a dust suction pipe 414 is connected to one side of the arc plate 48, the other end of the dust suction pipe 414 is connected to and connected to a rotating disk 415, the other end of the rotating disk 415 is connected and rotatably connected to a positioning disk 418 fixedly mounted on the moving seat 41, a delivery pipe 416 is connected to the top of the rotating disk 415, the other end of the delivery pipe 416 is provided with a collection box 417 fixedly mounted on the moving seat 41, a pump body is provided on the collection box 417, and the pump body is connected to the delivery pipe 416. When cleaning the surface of the terminal block 3 By starting the pump body, the dust or debris generated during the cleaning process is sucked into the dust suction hole and enters the rotating disk 415 through the dust suction pipe 414. It is worth noting that although the rotating disk 415 and the positioning disk 418 are rotatably connected, this design allows the dust suction airflow to pass unimpeded, maintaining the dust suction efficiency. The sucked airflow continues to flow to the collection box 417 through the delivery pipe 416. In the collection box 417, due to the negative pressure generated by the pump body, the dust or debris is separated and deposited in the collection box 417, and the clean air is released after being filtered through the collection box 417.

[0034] In the embodiment of the present invention, in the process of detecting the transformer body 2, it is first necessary to start the adjustment motor 436. The start of the motor will drive the screw rod 435 to rotate synchronously. As the screw rod 435 rotates, the moving seat 41 will also move synchronously. The movement of the moving seat 41 will further drive the detection head 43 and the sleeve 44 to move synchronously, so that the detection head 43 can detect different terminals 3 on the transformer body 2 one by one.

[0035] When the detection head 43 moves to the position of a specific terminal 3, the next operation is to start the second cylinder 411, which will push the adjustment plate 412 to move, and the movement of the adjustment plate 412 will drive the rotating plate 47 to rotate, so that the rotating plate 47 drives the arc plate 48 to rotate inward, so that the arc plate 48 approaches one side of the terminal 3, and as the arc plate 48 approaches, the bristles 49 will contact the surface of the terminal 3;

[0036] In order to further clean the outer wall of the terminal block 3, it is necessary to start the servo motor 420. The start of the motor will drive the active gear 421 to rotate synchronously. The rotation of the active gear 421 will cause the gear ring 46 meshing therewith to rotate synchronously, thereby driving the rotating plate 47, the arc plate 48 and the bristles 49 to rotate synchronously. When the bristles 49 contact the outer wall of the terminal block 3 and rotate, the dirt, dust or other impurities on the outer wall of the terminal block 3 can be effectively cleaned. Through such cleaning work, the insulation resistance tester body 432 can more accurately inspect and measure the terminal block 3, which helps to find potential connection problems, corrosion or wear, etc., thereby avoiding misjudgment or missed detection. After the interference factors of dirt and impurities are eliminated, the accuracy and reliability of the test results can be improved. The cleaned terminal block 3 is more easily identified and measured by the insulation resistance tester body 432, thereby reducing manual intervention and debugging time in the detection process, which helps to improve detection efficiency and shorten the detection cycle.

[0037] In the process of cleaning the terminal 3, the pump body needs to be started at the same time to ensure that the dust or debris generated during the cleaning process can be sucked into the dust suction hole. These sucked materials will enter the rotating disk 415 through the dust suction pipe 414. It is worth noting that although the rotating disk 415 and the positioning disk 418 are rotatably connected, this design allows the dust suction airflow to pass unimpeded, thereby maintaining the dust suction efficiency. The sucked airflow continues to flow to the collection box 417 through the conveying pipe 416. In the collection box 417, due to the negative pressure generated by the pump body, the dust or debris is separated and deposited in the collection box 417, and the clean air is released after being filtered through the collection box 417, thereby keeping the working area clean. This is particularly important for the detection of precision electronic or electrical equipment, because dust and debris may affect the normal operation of the equipment and the accuracy of the detection results. By removing the dust and debris on and around the terminal 3, it helps to ensure that the detection equipment such as the insulation resistance tester can detect and process the transformer body 2, which reduces the possibility of misjudgment or missed detection due to pollution;

[0038] After completing the cleaning contact of the terminal 3, the next operation is to start the second cylinder 411 to move the adjustment plate 412 inward. The movement of the adjustment plate 412 will drive the rotating plate 47, and then the arc plate 48 will rotate outward. Then, start the first cylinder 42 to move the detection head 43 and the sleeve 44 to one side of the transformer body 2. In this way, the position of the arc plate 48 will correspond to the position of the terminal 3. Subsequently, the sleeve 44 will be sleeved on the terminal 3, and the detection head 43 will be connected to the terminal 3. After the E-end wire 434 is connected to the ground, the transformer body 2 is detected by starting the insulation resistance tester body 432, and the insulation resistance value is recorded.

[0039] Embodiment 2: Combination Figure 8 , Fig. 9 As shown, on the basis of the first embodiment, on both sides of the fixed disk 45, the positioning shaft 422 is rotatably connected, and the positioning shaft 422 is fixedly connected to the driven gear 423 meshing with the driving gear 421, and one end of the positioning shaft 422 is also fixedly connected to the toggle rod 429, and the two sides of the surface of the fixed disk 45 are fixedly connected to the mounting frame 424, and the mounting frame 424 is slidably connected to the knocking rod 425 in the vertical direction. The position of the knocking rod 425 corresponds to the rotating plate 47 and the arc rod 413, and the top of the knocking rod 425 is rotatably connected to the transmission rod 426, and the other end of the transmission rod 426 is rotatably connected to the rotating rod 427. The other end of the moving rod 427 is sleeved on the positioning shaft 422, and the outer wall of the rotating rod 427 is fixedly connected with a protrusion 428, and the position of the protrusion 428 corresponds to that of the toggle rod 429. The outer wall of the knocking rod 425 is fixedly connected with a limit block 430, and a damping spring 431 sleeved on the knocking rod 425 is arranged between the limit block 430 and the mounting frame 424. When the driving gear 421 is driven to rotate by the servo motor 420, the driving gear 421 will drive the meshing driven gear 423 and the positioning shaft 422 to rotate synchronously. During the rotation process, the positioning shaft 422 will drive the toggle rod 429 to rotate synchronously, so that the rotating toggle The movable rod 429 moves the protrusion 428 and the rotating rod 427. When the rotating rod 427 rotates, it drives the transmission rod 426 to move. The transmission rod 426 then drives the knocking rod 425 and the limit block 430 to move outward and compress the damping spring 431. As the toggle rod 429 continues to rotate, when it is no longer in contact with the protrusion 428 and the rotating rod 427, the limit block 430 and the knocking rod 425 are pushed to move inward under the elastic force of the damping spring 431, so that the knocking rod 425 knocks the rotating plate 47 and the arc rod 413. This knocking process causes the rotating plate 47 and the arc rod 413 to transmit the vibration to the brush On the bristles 49, vibration can enhance the friction and contact frequency between the bristles 49 and the surface of the terminal 3 to be cleaned, thereby more effectively removing stains, dust and other impurities. This mechanical vibration method can significantly improve the cleaning efficiency, and through vibration cleaning, the dirt and wear on the surface of the bristles 49 can be regularly removed to prevent the bristles 49 from premature aging and hardening, thereby extending the service life of the bristles 49. Vibration cleaning helps to maintain the softness and elasticity of the bristles 49, so that it can better adapt to the shape and contour of the surface to be cleaned during use, thereby improving the cleaning effect while reducing the damage of the bristles 49 to the surface to be cleaned.

[0040] In the embodiment of the present invention, when the driving gear 421 is driven to rotate by the servo motor 420, the driving gear 421 will rotate synchronously with the meshing driven gear 423 and the positioning shaft 422. During the rotation process, the positioning shaft 422 will drive the toggle rod 429 to rotate synchronously. As the toggle rod 429 rotates, it will toggle the protrusion 428 and the rotating rod 427, so that the rotating rod 427 can drive the transmission rod 426 to move. The movement of the transmission rod 426 will further drive the knocking rod 425 and the limit block 430 to move outward and compress the damping spring 431. As the toggle rod 429 continues to rotate, when it no longer contacts the protrusion 428 and the rotating rod 427, the elastic force of the damping spring 431 will begin to play a role, pushing the limit block 430 and the knocking rod 425 to move inward. This action The knocking rod 425 is enabled to knock the rotating plate 47 and the arc rod 413. In this way, the rotating plate 47 and the arc rod 413 can transmit the vibration to the bristles 49. The addition of vibration can significantly enhance the friction and contact frequency between the bristles 49 and the surface of the terminal 3 being cleaned, thereby more effectively removing stains, dust and other impurities. This mechanical vibration method can not only significantly improve the cleaning efficiency, but also through vibration cleaning, it can regularly remove dirt and wear on the surface of the bristles 49, prevent the bristles 49 from premature aging and hardening, thereby extending the service life of the bristles 49. Vibration cleaning also helps to maintain the softness and elasticity of the bristles 49, so that it can better adapt to the shape and contour of the surface being cleaned during use, while improving the cleaning effect, it also reduces the damage of the bristles 49 to the surface being cleaned.

[0041] Working principle of dry-type transformer test device:

[0042] Step 1: Turn on the adjusting motor 436 to drive the screw rod 435 to rotate synchronously, and the screw rod 435 drives the moving seat 41 to move synchronously, so that the moving seat 41 drives the detection head 43 and the sleeve 44 to move synchronously, so that the detection head 43 detects and processes different terminals 3; when the detection head 43 moves to the position of the terminal 3, the second cylinder 411 is turned on to drive the adjusting plate 412 to move, so that the rotating plate 47 can be driven to rotate, so that the rotating plate 47 drives the arc plate 48 to rotate inward, so that the arc plate 48 is close to the side of the terminal 3, so that the bristles 49 are in contact with the surface of the terminal 3;

[0043] Step 2: Turn on the servo motor 420 to drive the driving gear 421 to rotate synchronously, so that the driving gear 421 drives the meshing ring gear 46 to rotate synchronously, so that the ring gear 46 drives the rotating plate 47, the arc plate 48 and the bristles 49 to rotate synchronously, so that when the arc plate 48 and the bristles 49 rotate synchronously, the rotating bristles 49 clean the outer wall of the terminal 3;

[0044] Step 3: During the cleaning process, the pump body is turned on, and the dust or debris generated during the cleaning process is sucked into the dust suction hole and enters the rotating disk 415 through the dust suction pipe 414. It is worth noting that although the rotating disk 415 and the positioning disk 418 are rotatably connected, this design allows the dust suction airflow to pass unimpeded, maintaining the dust suction efficiency. The sucked airflow continues to flow to the collection box 417 through the delivery pipe 416. In the collection box 417, due to the negative pressure generated by the pump body, the dust or debris is separated and deposited in the collection box 417, and the clean air is released back to the atmosphere through the special design of the collection box 417, such as the filter screen;

[0045] Step 4, after cleaning the contact of the terminal 3, the second cylinder 411 is turned on to drive the adjustment plate 412 to move inward, so that the rotating plate 47 drives the arc plate 48 to rotate outward, and then the first cylinder 42 is turned on to drive the detection head 43 and the sleeve 44 to move to the side of the transformer body 2, so that the position of the arc plate 48 corresponds to the position of the terminal 3, and then the sleeve 44 is sleeved on the terminal 3, and the detection head 43 is connected to the terminal 3, and the E-end wire 434 is connected to the ground, and then the insulation resistance tester body 432 is turned on to detect the transformer body 2 and record the insulation resistance value.
