[0001] The present invention relates to the technical field of transformer detection, in particular to a transformer detection device. Background Art

[0002] With the continuous development of the power industry, the performance and safety of transformers as core equipment in the power system are increasingly valued. The transformer oil pillow capsule body is an important part of the transformer, and its air tightness directly affects the normal operation and service life of the transformer. Therefore, it is particularly important to develop an efficient and accurate transformer oil pillow capsule body air tightness detection device.

[0003] At present, there are some transformer detection devices on the market. Most of these devices use professional detection equipment such as barometers to perform air tightness tests. Although these devices can provide relatively accurate measurement results, they also have some obvious defects:

At the same time, the ease of operation also greatly improves work efficiency; through immediate exhaust detection, capsule bodies with unqualified air tightness can be quickly discovered, thereby achieving immediate quality control, which helps to promptly remove unqualified products and ensure continuous high-quality output of the production line.

[0021] Through the precise control of the second cylinder, the movable plate and the second baffle can achieve precise positioning and blocking of the connecting pipe, providing a stable foundation for the subsequent inflation process. At the same time, the precise sealing connection between the gas supply pipe and the air inlet pipe ensures the effectiveness and safety of the inflation process. Using an air pump for inflation, external air or specified gas can be quickly pressurized and sent into the capsule body, improving the inflation efficiency. The design of the one-way valve can automatically close the air inlet pipe after the gas supply pipe is removed, effectively preventing the backflow of gas in the capsule body from being discharged. This not only maintains the stability of the gas pressure in the capsule body, but also facilitates the accuracy of subsequent detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] A control rod 421 is fixedly connected to the top of the exhaust plate 45, and the top of the control rod 421 is fixedly connected to the sliding rod 420.

[0039] A slide groove 425 is provided on the crossbar 41, and a limiting ball 423 is slidably installed in the slide groove 425, and a lifting plate 426 for controlling the moving position of the limiting ball 423 is fixedly connected to the outer end of the slide groove 425;

[0040] The positioning member 46 includes a connecting block 428 fixedly mounted on the cross bar 41, and an adjusting plate 427 slidably mounted on the outer end of the lifting plate 426 in the vertical direction. A mounting frame 429 is fixedly connected to the top of the connecting block 428, and one end of the adjusting plate 427 is fixedly connected to an arc-shaped pressing plate 430 slidably mounted on the mounting frame 429, and the position of one end of the arc-shaped pressing plate 430 is mutually adapted to the position of the transformer oil pillow capsule body 6 on the sliding plate 3, and a fourth damping spring 431 mounted on the mounting frame 429 is arranged between the arc-shaped pressing plate 430 and the connecting block 428.

[0041] In the embodiment of the present invention, first, ensure that the surface of the conveyor belt 2 is clean and free of foreign matter to avoid damage to the transformer oil pillow capsule body 6 during transportation. Then, the transformer oil pillow capsule bodies 6 to be tested are placed one by one and stably on the conveyor belt 2 to ensure that the position of each capsule body is correct, especially the connecting pipe 61 at the top thereof, which needs to be accurately placed in the center of the slideway between the two slide boards 3;

[0042] Start the motor and drive the conveyor belt 2 to move forward at a stable speed to transport the transformer oil pillow capsule body 6 to the area of ​​the detection component 4 one by one. When the front end of the capsule body 6 contacts the first stop bar 414, the motor temporarily stops working to achieve precise positioning. At this time, the capsule body 6 is in a state to be detected and is ready for the next step of operation;

[0043] The first cylinder 411 in the first intermittent discharge member 43 starts to work, driving the moving seat 49 and the two T-shaped plates 410 to move along the preset track. Under the elastic action of the two first damping springs 415, the two centrally symmetrical T-shaped plates 410 cooperate with the guide wheels 413 to drive the two vertical rods 412 to reciprocate up and down on the U-shaped frame 42. This movement drives the first blocking rod 414 to intermittently move up and down on the slideway of the slide plate 3, thereby realizing the intermittent transportation of the transformer oil pillow capsule body 6. This design not only improves the transportation efficiency, but also ensures the stability of the capsule body during the transportation process.

[0044] Under the cooperation of the first intermittent discharge member 43 and the second intermittent discharge member 44, the front T-shaped plate 410 moves inward, while the rear T-shaped plate 410 moves outward. This action enables the transformer oil pillow capsule body 6 located at the first intermittent discharge member 43 to be accurately pushed to the area of ​​the inflation component 5. At the same time, the second stop rod 54 quickly positions and fixes the connecting pipe 61 to ensure stability during the inflation process.

[0045] The inflation component 5 is started to inflate the transformer oil pillow capsule body 6. During the inflation process, when the capsule body is filled with gas, the elastic force of the second damping spring 419 pushes the moving block 418, the sliding rod 420 and other components to move inward, driving the exhaust plate 45 to clamp the transformer oil pillow capsule body 6 on both sides. During the clamping process, the exhaust plate 45 tries to slowly discharge the gas in the transformer oil pillow capsule body 6. By observing the morphological changes and gas escape during the exhaust process, its air tightness can be intuitively judged. This intuitiveness makes the detection process relatively simple and clear. Compared with the use of detection equipment such as a barometer, the method of clamping and exhausting using the exhaust plate 45 does not require complicated operating procedures and professional equipment, so it is more convenient to operate. This method is low-cost and does not require the purchase of additional professional equipment. It is suitable for some rapid detection under limited budgets or emergency situations.

[0046] According to the exhaust test results, it can automatically determine whether the air tightness of the transformer oil pillow capsule body is qualified, and the unqualified capsule body can be removed in time.

[0047] Embodiment 2: Combination Figure 7 As shown, on the basis of embodiment one, the inflation component 5 includes a connecting plate 51 fixedly installed between the fixing frames 47, a second cylinder 52 is fixedly connected to the bottom of the connecting plate 51, a movable plate 53 is provided at the output end of the second cylinder 52, a second baffle 54 is provided at the bottom of the movable plate 53, an air pump 55 is provided on the movable plate 53, an air intake pipe 56 is provided at the input end of the air pump 55, and an air supply pipe 57 is provided at the output end, the air supply pipe 57 is vertically installed at the bottom of the movable plate 53, and the length is shorter than the second baffle 54.

[0048] In the embodiment of the present invention, first, the second cylinder 52 is started to drive the movable plate 53 and the second baffle rod 54 connected thereto to move downward synchronously. In this process, the movable plate 53 acts as a transmission member to ensure that the second baffle rod 54 can accurately and stably move to a predetermined position, that is, the slideway of the connecting pipe 61 of the transformer oil pillow capsule body 6. When the second baffle rod 54 is completely moved to this position, it will directly block the connecting pipe 61, which is convenient for the subsequent detection of the transformer oil pillow capsule body 6.

[0049] Then, the second cylinder 52 is closed to keep the movable plate 53 and the second stopper 54 at the current position. At this time, the arc-shaped pressure plate 430 has accurately positioned the connecting pipe 61 to ensure that it is in the best connection state. Next, the second cylinder 52 is started again, but this time its task is to continue to drive the movable plate 53 to move downward. However, the purpose of this movement is to enable the air delivery pipe 57 installed on the movable plate 53 to accurately achieve a sealed connection with the air intake pipe 63 on the connecting pipe 61. This step is crucial because it is directly related to the effectiveness and safety of the subsequent inflation process.

[0050] When the air delivery pipe 57 is completely sealed and connected with the air inlet pipe 63, the second air cylinder 52 is closed to keep the connection state stable, and then the air pump 55 is started. This device sucks in external air or specified gas through the air intake pipe 56, and sends it into the transformer oil pillow capsule body 6 through the air delivery pipe 57 after pressurization;

[0051] After the inflation is completed, the second cylinder 52 is started again to drive the moving plate 53 and the second stop rod 54 to move upward. At this time, the gas pipe 57 is smoothly moved out of the air inlet pipe 63, and the second stop rod 54 also releases the obstruction to the connecting pipe 61. In this process, the one-way valve 62 plays a key role. It can automatically close the air inlet pipe 63 after the gas pipe 57 is moved out, effectively preventing the gas in the transformer oil pillow capsule body 6 from backflowing out;

[0052] Finally, the detection component 4 is used to detect the transformer oil pillow capsule body 6 filled with gas.

[0053] Example 3: Combination Figure 8 As shown, on the basis of the second embodiment, a connecting pipe 61 is arranged on the top of the transformer oil pillow capsule body 6, and the connecting pipe 61 is used for sliding installation on the slideway between the two slide plates 3, and an air intake pipe 63 connected to the transformer oil pillow capsule body 6 is arranged on the inner side of the connecting pipe 61, and a one-way valve 62 acting on the air intake pipe 63 is arranged on the one-way valve 62.

[0054] In the embodiment of the present invention, the precise specifications of the air inlet pipe 63 and the detailed specifications of the air delivery pipe 57 are carefully designed to ensure that the two can achieve perfect mutual adaptation. This adaptability not only enables the air delivery pipe 57 to be easily and firmly sealed and inserted into the interior of the air inlet pipe 63, but also ensures the air tightness during the gas delivery process, avoiding gas leakage or unnecessary loss;

[0055] When the gas delivery pipe 57 is tightly connected with the air inlet pipe 63, the transformer oil pillow capsule body 6 can be efficiently delivered. In this process, the one-way valve 62 plays a vital role. It is cleverly installed on the air inlet pipe 63, like an intelligent gate, strictly controlling the flow direction of the gas. Specifically, the one-way valve 62 allows the gas to enter the transformer oil pillow capsule body 6 in one direction, ensuring that the gas can smoothly and effectively inflate or replenish the oil pillow capsule. At the same time, the one-way valve 62 also has an excellent anti-backflow function, which resolutely prevents the possibility of gas being discharged from the air inlet pipe 63.

[0056] To sum up, the precise adaptation of the air inlet pipe 63 and the air delivery pipe 57, as well as the ingenious application of the one-way valve 62, together constitute an important part of the gas delivery system of the transformer oil pillow capsule body 6. They work together to ensure that the gas can enter the transformer oil pillow capsule body 6 safely and efficiently, facilitating the subsequent detection and processing of the transformer oil pillow capsule body 6.

[0057] Working principle of transformer detection device:

[0058] Step 1: Place the transformer oil pillow capsule body 6 to be tested on the conveyor belt 2 in sequence, and place the connecting pipe 61 on the top of the transformer oil pillow capsule body 6 on the slideway between the two slide plates 3, and drive the conveyor belt 2 to transport the transformer oil pillow capsule body 6 to one side of the detection component 4 by turning on the motor, so that the transformer oil pillow capsule body 6 contacts the first stop rod 414;

[0059] Step 2: When the first intermittent discharge member 43 and the second intermittent discharge member 44 are working, the T-shaped plate 410 at the front end moves inward, and the T-shaped plate 410 at the rear end moves outward. At this time, the transformer oil pillow capsule body 6 at the first intermittent discharge member 43 can be transported to the inflation assembly 5, and the position of the connecting pipe 61 is limited by the second stop rod 54;

[0060] The T-shaped plate 410 at the front end can drive the extension rod 432, the adjustment rod 416, the moving block 418, the sliding rod 420, the control rod 421, and the exhaust plate 45 to the inside, so that the control rod 421 cooperates with the limiting ball 423 to slide inward on the lifting plate 426, that is, the limiting ball 423 moves from the lifting plate 426 to the slide groove 425. At this time, under the elastic force of the third damping spring 424, the exhaust plate 45, the control rod 421, the sliding rod 420, the moving block 418, the guide rod 417 and the adjustment rod 416 can be pushed downward, so that the position of the control rod 421 corresponds to the position of the transformer oil pillow capsule body 6. When the sliding rod 420 moves downward, it can drive the arc pressure plate 430 located on the mounting frame 429 to move downward and compress the fourth damping spring 431, so that the arc pressure plate 430 can press and position the intake pipe 63 located on the sliding plate 3;

[0061] Step 3, then open the second cylinder 52 to drive the movable plate 53 to move downward, so that the gas delivery pipe 57 is sealed and connected with the air inlet pipe 63 on the connecting pipe 61. After the connection is completed, close the second cylinder 52, and then open the air pump 55, cooperate with the suction pipe 56, and press the gas into the transformer oil pillow capsule body 6 through the gas delivery pipe 57. After the inflation is completed, open the second cylinder 52 to drive the movable plate 53 and the second baffle 54 to move upward, so that the gas delivery pipe 57 is moved out of the air inlet pipe 63, and the second baffle 54 no longer blocks the connecting pipe 61. At this time, the one-way valve 62 can close the air inlet pipe 63;

[0062] Step 4, after the transformer oil pillow capsule body 6 is filled with gas, the elastic force of the second damping spring 419 can push the moving block 418 and the sliding rod 420 to move inward, thereby driving the control rod 421, the limiting ball 423, and the exhaust plate 45 to move inward, so that the transformer oil pillow capsule bodies 6 on both sides can clamp the exhaust plate 45, and at the same time, under the elastic force of the second damping spring 419, the exhaust plate 45 can be pushed to continuously clamp the transformer oil pillow capsule body 6, and try to slowly discharge the gas in the transformer oil pillow capsule body 6, and judge its air tightness by observing the morphological changes of the transformer oil pillow capsule body 6 during the exhaust process, whether there is continuous gas leakage, and whether the transformer oil pillow capsule body 6 maintains a certain shape or shrinks rapidly after exhaust.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
