Description

Technical Field

[0001] The present invention relates to the technical field of noise source localization devices applied to transformers and reactors, and particularly relates to a noise source localization device applied to transformers and reactors. Background Art

[0002] In the power system, transformers and reactors are key equipment, and the stability of their operating states is crucial. However, during long-term operation, these devices inevitably generate noise. The noise not only pollutes the surrounding environment and interferes with people's normal life and work, but more importantly, it is often an external manifestation of internal faults or abnormalities in the devices. For example, problems such as loose iron cores and short-circuited windings may cause changes in noise. With the continuous expansion of the scale of the power system and the development trend of intelligent management of equipment, there is an urgent need for a device that can quickly and accurately locate the noise sources of transformers and reactors. This device should not only be able to work stably in a complex environment but also have high-precision positioning capabilities, providing a reliable basis for equipment maintenance and fault troubleshooting, thereby ensuring the safe and stable operation of the power system.

[0003] The applicant found through retrieval that the Chinese patent disclosed a "noise source localization device applied to transformers and reactors", and its publication (announcement) number is "CN 203037774 U". This patent mainly collects the acoustic wave signals of transformers and reactors through a microphone sensor array, calculates the phase differences of the signals received by each sensor, determines the position of the sound source according to the phased array principle, measures the amplitude of the sound source, and displays the spatial distribution of the sound source in the form of an image. However, this patent cannot finely adjust the orientation angle of the localization device from multiple angles to obtain more accurate and comprehensive noise signals. Then, in the actual use process, it may be difficult to capture the signal characteristics that can accurately reflect the position of the noise source, resulting in a decrease in positioning accuracy. For this reason, we propose a noise source localization device applied to transformers and reactors. Summary of the Invention

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] Example 1

[0018] Please refer to the attached Figure 1 and the attached Figure 3 - the attached Figure 5 There is a noise source localization device applied to transformers and reactors, which includes a trolley 1. Above the trolley 1, there is an adjustment component 4. The adjustment component 4 includes a first motor 401, a limiting rod 407, and a support frame 408. The first motor 401 is connected to a limiting plate 403 through a threaded rod 402. The threaded rod 402 is connected to a support plate 405 through a moving block 404. The support frame 408 is connected to a rotating rod 410 through a second motor 409. The rotating rod 410 is connected to a connecting plate 412 through a turntable 411. At the four corners of the bottom of the trolley 1, universal wheels 2 are fixedly connected. On the top of the connecting plate 412, a positioning device main body 3 is fixedly installed. One end of the threaded rod 402 is fixedly connected to the output end of the first motor 401, and the other end of the threaded rod 402 is rotatably connected to the surface of the limiting plate 403. There are two groups of moving blocks 404. One group of moving blocks 404 is threadedly connected to the outer wall of the threaded rod 402, and the other group of moving blocks 404 is slidably connected to the outer wall of the limiting rod 407. The corresponding sides of the two groups of moving blocks 404 are fixedly connected to both ends of the support plate 405. On the top of the support plate 405, a placement groove 406 is opened. One end of the limiting rod 407 is fixedly connected to the surface of the limiting plate 403. The support frame 408 is fixedly installed at the bottom of the support plate 405. The second motor 409 is fixedly installed on the inner wall of the support frame 408. One end of the rotating rod 410 is fixedly connected to the output end of the second motor 409. The outer wall of the rotating rod 410 is rotatably connected to the inner wall of the support plate 405. The other end of the rotating rod 410 is fixedly connected to the inside of the turntable 411. The turntable 411 is arranged inside the placement groove 406. The connecting plate 412 is fixedly connected to the top of the turntable 411.

[0019] The size of the turntable 411 is smaller than that of the placement groove 406. This enables sufficient space for rotation after the turntable 411 is placed in the placement groove 406. When the positioning device main body 3 rotates, it will not contact other components, and the rotation operation can be smoothly completed.

[0020] Specifically, through the set adjustment component 4, the staff moves the trolley 1 to the noise location of the transformer and reactor, turns on the first motor 401 to drive the threaded rod 402 to rotate, and the moving block 404 moves accordingly, driving the support plate 405, so that the positioning device main body 3 on the top of the support plate 405 reaches the noise position, completing the preliminary accurate positioning and improving the positioning efficiency. Then, turn on the second motor 409 to drive the rotating rod 410 to rotate, and the connecting plate 412 rotates accordingly, finely adjusting the orientation angle of the positioning device main body 3. Through multi-angle fine adjustment, more accurate and comprehensive noise signals can be obtained, helping the positioning device main body 3 to more accurately determine the noise source and improving the positioning accuracy.

[0021] Example 2

[0022] Please refer to the appendix Figure 1 and the appendix Figure 6 , and on the basis of Example 1, it is further obtained that a moving component 5 is provided above the trolley 1 and behind the adjusting component 4. The moving component 5 includes a fixed frame 501 and a grip rod 502. The fixed frame 501 is fixedly installed on the top of the trolley 1. The lower end of the grip rod 502 is fixedly connected with a fixed disk 503. The bottom of the fixed disk 503 is fixedly connected with a lead screw 504. The outer wall of the lead screw 504 is rotatably connected to the inner wall of the top of the fixed frame 501. The lower end of the lead screw 504 is rotatably connected to the inner bottom wall of the fixed frame 501. A connecting plate 505 is threadedly connected to the outer wall of the lead screw 504. The first motor 401 is fixedly installed on the front of the connecting plate 505. The rear end of the limiting rod 407 is fixedly connected to the front of the connecting plate 505 and is located on the left side of the first motor 401. The left end of the connecting plate 505 is fixedly connected with a slider 506. A chute 507 is opened on the left inner wall of the fixed frame 501. The slider 506 is slidably connected to the inside of the chute 507.

[0023] There is still a certain distance between the right end of the connecting plate 505 and the right inner wall of the fixed frame 501. The surface of the grip rod 502 is provided with friction lines, and this design can increase the friction force when the staff holds the grip rod 502.

[0024] Specifically, through the provided moving component 5, the staff can hold the grip rod 502 and rotate it, driving the fixed disk 503 and the lead screw 504 to rotate, making the connecting plate 505 move up and down. At the same time, the slider 506 will also move up and down synchronously in the chute 507, thereby adjusting the height of the positioning device main body 3. By adjusting the height of the positioning device main body 3, it can be located at the best signal receiving position to prevent the signal from being blocked or weakened due to improper height.

[0025] Working principle of the present invention: The present invention is a noise source localization device applied to transformers and reactors. First, the staff push the trolley 1. Through the flexibility of the universal wheels 2, the trolley 1 is moved to the place where the transformer and the reactor generate noise. Then, the staff start the first motor 401, and the first motor 401 drives the threaded rod 402 to rotate. A group of moving blocks 404 will move on the outer wall of the threaded rod 402, and the other group of moving blocks 404 will also move on the outer wall of the limiting rod 407, thereby driving the support plate 405 to move. As the support plate 405 moves, the positioning device main body 3 located on its top is moved to the approximate position where the noise occurs, completing the preliminary precise positioning. Then, the staff start the second motor 409, and the second motor 409 drives the rotating rod 410 to rotate. When the rotating rod 410 rotates, it drives the turntable 411 to rotate in the placement groove 406, and the connecting plate 412 rotates along with the turntable 411, thereby finely adjusting the orientation angle of the positioning device main body 3. By finely adjusting the orientation angle of the positioning device main body 3 multiple times, more accurate and comprehensive noise signals are obtained from different directions, helping the positioning device main body 3 to more precisely determine the noise source position and improve the positioning accuracy. Secondly, the staff hold the grip 502 and rotate the grip 502. The fixed disk 503 fixedly connected to the lower end of the grip 502 rotates accordingly, and the lead screw 504 fixedly connected to the bottom of the fixed disk 503 also rotates together. The connecting plate 505 threadedly connected to the outer wall of the lead screw 504 moves up and down under the rotation of the lead screw 504. At the same time, the slider 506 fixedly connected to the left end of the connecting plate 505 moves up and down synchronously in the chute 507 opened on the left inner wall of the fixed frame 501, playing a role in stabilizing the movement of the connecting plate 505. The first motor 401 and the limiting rod 407 are both fixedly installed on the connecting plate 505. Therefore, as the connecting plate 505 moves up and down, the height of the adjusting assembly 4 and the positioning device main body 3 located on the top of the support plate 405 also changes accordingly. By adjusting the height of the positioning device main body 3, it is located at the best signal receiving position, avoiding signal occlusion or weakening due to improper height.
