Description

Technical Field

[0001] This invention relates to the field of coupler technology, and more particularly to a high-frequency partial discharge signal coupler. Background Technology

[0002] A coupler is a device in a microwave system that proportionally splits a single microwave power source into several paths. When using a coupler, the main body of the coupler is connected to the circuit. The main functions of a high-frequency partial discharge signal coupler include signal capture, power monitoring and regulation, system protection, and impedance matching. In addition, high-frequency partial discharge signal couplers also have advantages such as high sensitivity, wide bandwidth, and strong anti-interference ability, and can accurately capture high-frequency current pulses generated by partial discharge.

[0003] In their daily work, the inventors discovered that couplers still have at least the following problems: When using a coupler, the coupler body is connected to the line. The main functions of a high-frequency partial discharge signal coupler include signal capture, power monitoring and regulation, system protection, and impedance matching. In addition, high-frequency partial discharge signal couplers also have advantages such as high sensitivity, wide bandwidth, and strong anti-interference ability, and can accurately capture high-frequency current pulses generated by partial discharge. However, in actual use, the connecting wire is plugged into the coupler body. In this way, the connecting wire and the coupler are easy to separate during use, which affects the use of the coupler to a certain extent. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-frequency partial discharge signal coupler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-frequency partial discharge signal coupler, comprising a coupler body, a first connection port installed on one side of the coupler body, a second connection port evenly arranged on the side of the coupler body away from the first connection port, a fixing device provided on one side of the first connection port, a connecting device provided on one side of the coupler body, the fixing device comprising a rectangular strip, a connector head slidably inserted into the inner wall of the first connection port, a connecting sleeve fixedly connected to one side of the connector head, the connecting sleeve being fitted onto the surface of the first connection port, a locking ring evenly fixedly connected to the surface of the connecting sleeve, the rectangular strip being fixedly connected to one side of the coupler body, a rotating frame being rotatably inserted into the rectangular strip, the end of the rotating frame away from the rectangular strip being located on one side of the connecting sleeve, a support ring being fixedly connected to the surface of the rotating frame, a first spring being fitted onto the surface of the rotating frame, one end of the first spring being fixedly connected to one side of the rectangular strip, and the end of the first spring near the rotating frame being fixedly connected to one side of the support ring.

[0006] The effect achieved by the above components is as follows: when using the fixing device, the connector is manually inserted into the first connection port. The torque force generated by the first spring drives the rotating frame to rotate on one side of the rectangular bar, and then one end of the rotating frame is pressed against the surface of the connecting sleeve, which to a certain extent restricts the connector inside the first connection port.

[0007] Preferably, a cylinder is rotatably fitted onto the surface of the rotating frame away from the rectangular strip. An arc-shaped plate is fixedly connected to one side of the cylinder. Protrusions are uniformly fixedly connected to the side of the arc-shaped plate away from the cylinder. Fixing rings are uniformly fixedly connected to the surface of the rotating frame. Two fixing rings are uniformly arranged at both ends of the cylinder. A rubber cylinder is fixedly connected to the surface of the connector. The arc-shaped plate is fitted onto the surface of the rubber cylinder.

[0008] The effect achieved by the above components is as follows: under the restriction of the fixed ring, the cylinder can be manually controlled to rotate on the surface of the rotating frame, so that the arc plate is sleeved on the surface of the rubber cylinder, and the protrusion is pressed against the surface of the rubber cylinder. This can prevent the arc plate from sliding on the surface of the connecting sleeve to a certain extent.

[0009] Preferably, locking rings are uniformly fixedly connected to the surface of the connector, and a sliding cylinder is slidably sleeved on the surface of the connector. The sliding cylinder is sleeved on the surface of the arc-shaped plate away from the protrusion. A first damping rod is uniformly fixedly connected to the end of the sliding cylinder away from the connector. The end of the first damping rod away from the rubber cylinder is fixedly connected to one side of the connector surface. A second spring is sleeved on the surface of the first damping rod. One end of the second spring is fixedly connected to one end of the sliding cylinder. The second spring is close to the first damping rod.

[0010] One end is fixedly connected to one side of the connector surface.

[0011] The effect achieved by the above components is that the sliding cylinder is pressed away from the connector by the second spring, thereby fitting the sliding cylinder onto the surface of the arc-shaped plate, which can effectively restrict the arc-shaped plate to the surface of the connector.

[0012] Preferably, a groove is provided on one side of the coupler body, and a fixing strip is slidably connected to the inner wall of the groove. Rubber blocks are uniformly fixedly connected to the side of the fixing strip near the coupler body. A second damping rod is fixedly connected to one side of the inner wall of the groove. The end of the second damping rod near the groove is fixedly connected to one side of the fixing strip. A third spring is sleeved on the surface of the second damping rod. One end of the third spring is fixedly connected to one side of the inner wall of the groove, and the end of the third spring near the second damping rod is fixedly connected to one side of the fixing strip.

[0013] The effect achieved by the above components is as follows: the fixing bar is pulled towards the coupler body by the third spring, so that the fixing bar is set on the side of the rotating frame away from the coupler body, and the rubber block is squeezed on one side of the rotating frame. This makes the rotating frame away from the first connection port, which makes it easier to insert the connector into the first connection port.

[0014] Preferably, the connecting device includes a connecting frame, which is slidably connected to the inner wall of the coupler body. A rubber plate is slidably connected to the inner wall of the coupler body. A fixing plate is fixedly connected to the side of the rubber plate away from the coupler body. A third damping rod is fixedly connected to one side of the inner wall of the coupler body. One end of the third damping rod away from the coupler body is fixedly connected to one side of the connecting frame. A fourth spring is sleeved on the surface of the third damping rod. One end of the fourth spring is fixedly connected to one side of the inner wall of the coupler body, and the other end of the fourth spring away from the third damping rod is fixedly connected to one side of the connecting frame.

[0015] The effect achieved by the above components is as follows: when using the connecting device, the fourth spring presses the connecting frame away from the coupler body, which makes it easier to move the parts set inside the connecting frame away from the inside of the coupler body. This facilitates the maintenance of the parts inside the coupler body. After the maintenance is completed, the connecting frame is slid into the inside of the coupler body and the rubber plate is pressed into the inside of the coupler body, which allows the parts to be stored.

[0016] Preferably, the bottom of the connecting frame is provided with a storage groove, the top of the inner wall of the storage groove is fixedly connected to a fourth damping rod, the end of the fourth damping rod away from the storage groove is fixedly connected to a support block, a fifth spring is sleeved on the surface of the fourth damping rod, one end of the fifth spring is fixedly connected to the top of the inner wall of the storage groove, and the end of the fifth spring near the fourth damping rod is fixedly connected to one side of the support block.

[0017] The effect achieved by the above components is that after the connecting frame is squeezed out of the coupler body, the fifth spring presses the support block away from the receiving groove, so that the connecting frame can be supported by the support block.

[0018] Preferably, a fifth damping rod is uniformly fixedly connected to the top of the fixed plate, an L-shaped plate is fixedly connected to the top of the fifth damping rod, a sixth spring is sleeved on the surface of the fifth damping rod, one end of the sixth spring is fixedly connected to the top of the fixed plate, the end of the sixth spring near the fifth damping rod is fixedly connected to the bottom of one side of the L-shaped plate, a rubber rod is slidably inserted through the end of the L-shaped plate away from the fifth damping rod, and one end of the rubber rod is fixedly connected to one side of the coupler body.

[0019] The effect achieved by the above components is as follows: the L-shaped plate is pulled towards the fixed plate by the sixth spring, and then the L-shaped plate is fitted onto the top of the coupler body, and then the rubber rod is squeezed into the interior of one side of the L-shaped plate, which makes it easier to restrict the fixed plate to one side of the coupler body.

[0020] Preferably, a positioning frame is fixedly connected to the top of the coupler body, a positioning strip is slidably connected to the inner wall of the positioning frame, a groove is provided on one side of the positioning strip, the inner wall of the groove is slidably connected to one side of the L-shaped plate, a rubber strip is fixedly connected to the inner wall of the groove, a sixth damping rod is fixedly connected to one side of the inner wall of the positioning frame, the end of the sixth damping rod away from the positioning frame is fixedly connected to one end of the positioning strip, a seventh spring is sleeved on the surface of the sixth damping rod, one end of the seventh spring is fixedly connected to one side of the inner wall of the positioning frame, and the end of the seventh spring near the sixth damping rod is fixedly connected to one side of the positioning strip.

[0021] The effect achieved by the above components is as follows: the positioning strip is pressed away from the positioning frame by the seventh spring, thereby pressing the L-shaped plate into the inside of the groove, and pressing the rubber strip to the side of the L-shaped plate away from the coupler body, thereby restricting the L-shaped plate inside the groove.

[0022] In this invention, by setting a fixing device, when using the fixing device, the connector is manually inserted into the first connection port. The torque force generated by the first spring drives the rotating frame to rotate on one side of the rectangular bar, and then one end of the rotating frame is pressed against the surface of the connecting sleeve, thus restricting the connector to the inside of the first connection port to a certain extent.

[0033] Example 1, as shown in Figures 1-8, is a high-frequency partial discharge signal coupler. A first connection port 2 is installed on one side of the coupler body 1, and second connection ports 3 are evenly arranged on the side of the coupler body 1 away from the first connection port 2. A fixing device 4 is provided on one side of the first connection port 2, and a connecting device 5 is provided on one side of the coupler body 1. When using the coupler, the coupler body 1 is connected to the line. The main functions of the high-frequency partial discharge signal coupler include signal capture, power monitoring and regulation, system protection, and impedance matching. In addition, the high-frequency partial discharge signal coupler also has the advantages of high sensitivity, wide bandwidth, and strong anti-interference ability, and can accurately capture the high-frequency current pulses generated by partial discharge.

[0034] Reference Figure 2 to Figure 5The fixing device 4 includes a rectangular bar 401. A connector 412 is slidably inserted into the inner wall of the first connecting port 2. A connecting sleeve 408 is fixedly connected to one side of the connector 412. The connecting sleeve 408 is fitted onto the surface of the first connecting port 2. A locking ring 410 is uniformly fixedly connected to the surface of the connecting sleeve 408. The rectangular bar 401 is fixedly connected to one side of the coupler body 1. A rotating frame 402 is rotatably inserted into the rectangular bar 401. The end of the rotating frame 402 away from the rectangular bar 401 is located on one side of the connecting sleeve 408. A support ring 406 is fixedly connected to the surface of the rotating frame 402. A first spring 407 is fitted onto the surface of the rotating frame 402. One end of the first spring 407 is fixedly connected to one side of the rectangular bar 401. The end of the first spring 407 near the rotating frame 402 is fixedly connected to one side of the support ring 406. When using the fixing device 4, the connector 412 is manually inserted into the first connecting port 2, and the first spring 407... The generated torque force drives the rotating frame 402 to rotate on one side of the rectangular bar 401, causing one end of the rotating frame 402 to press against the surface of the connecting sleeve 408. This, to a certain extent, restricts the connector 412 inside the first connecting port 2. A cylinder 403 is rotatably fitted onto the surface of the rotating frame 402 away from the rectangular bar 401. An arc-shaped plate 404 is fixedly connected to one side of the cylinder 403. Protrusions 415 are uniformly fixedly connected to the side of the arc-shaped plate 404 away from the cylinder 403. Fixing rings 405 are uniformly fixedly connected to the surface of the rotating frame 402. Two fixing rings 405 are evenly distributed at both ends of the cylinder 403. A rubber cylinder 409 is fixedly connected to the surface of the connector 412. The arc-shaped plate 404 is fitted onto the surface of the rubber cylinder 409. Under the restriction of the fixing rings 405, the cylinder 403 is manually controlled to rotate on the surface of the rotating frame 402, thereby causing the arc-shaped plate 404 to be fitted onto the rubber cylinder 409. The surface of the rubber cylinder 409 is pressed against the surface of the rubber cylinder 409, which can prevent the arc plate 404 from sliding on the surface of the connecting sleeve 408 to a certain extent. A locking ring 410 is uniformly fixedly connected to the surface of the connector 412. A sliding cylinder 411 is slidably fitted onto the surface of the connector 412. The sliding cylinder 411 is fitted onto the surface of the arc plate 404 away from the protrusion 415. A first damping rod 413 is uniformly fixedly connected to the end of the sliding cylinder 411 away from the connector 412. The end of the first damping rod 413 away from the rubber cylinder 409 is fixedly connected to one side of the surface of the connector 412. A second spring 414 is fitted onto the surface of the first damping rod 413. One end of the second spring 414 is fixedly connected to one end of the sliding cylinder 411. The end of the second spring 414 near the first damping rod 413 is fixedly connected to one side of the surface of the connector 412.The second spring 414 presses the sliding cylinder 411 away from the connector 412, thereby fitting the sliding cylinder 411 onto the surface of the arc plate 404. This effectively confines the arc plate 404 to the surface of the connector sleeve 408. A groove 416 is provided on one side of the coupler body 1. A fixing strip 417 is slidably connected to the inner wall of the groove 416. Rubber blocks 418 are evenly fixedly connected to the side of the fixing strip 417 near the coupler body 1. A second damping rod 419 is fixedly connected to one side of the inner wall of the groove 416. One end of the second damping rod 419 near the groove 416 is fixedly connected to one side of the fixing strip 417. A third spring 420 is fitted on the surface of the second damping rod 419. One end of the third spring 420 is fixedly connected to one side of the inner wall of the groove 416. The end of the third spring 420 near the second damping rod 419 is fixedly connected to one side of the fixing strip 417. Pull the fixing strip 417 towards the coupler body 1, thereby positioning the fixing strip 417 on the side of the rotating frame 402 away from the coupler body 1, and pressing the rubber block 418 against one side of the rotating frame 402. This moves the rotating frame 402 away from the first connection port 2, making it easier to insert the connector 412 into the first connection port 2.

[0035] Reference Figure 6 to Figure 8 The connecting device 5 includes a connecting frame 501, which is connected to the coupler body 1.

[0036] The inner wall of the coupler body 1 is slidably connected to a rubber plate 505. A fixing plate 504 is fixedly connected to the side of the rubber plate 505 away from the coupler body 1. A third damping rod 502 is fixedly connected to one side of the inner wall of the coupler body 1. The end of the third damping rod 502 away from the coupler body 1 is fixedly connected to one side of the connecting frame 501. A fourth spring 503 is sleeved on the surface of the third damping rod 502. One end of the fourth spring 503 is fixedly connected to one side of the inner wall of the coupler body 1, and the end of the fourth spring 503 away from the third damping rod 502 is fixedly connected to one side of the connecting frame 501. When using the connecting device 5, the fourth spring 503 presses the connecting frame 501 away from the coupler body 1, which facilitates the removal of parts located inside the connecting frame 501 from the interior of the coupler body 1. This facilitates the maintenance of parts inside the coupler body 1. After maintenance is completed, the connecting frame 501 is slid back onto the coupler body 1. Inside the coupling body 1, the rubber plate 505 is squeezed into the interior of the coupling body 1, thus storing the parts. A storage groove 509 is provided at the bottom of the connecting frame 501. A fourth damping rod 510 is fixedly connected to the top of the inner wall of the storage groove 509. A support block 512 is fixedly connected to the end of the fourth damping rod 510 away from the storage groove 509. A fifth spring 511 is sleeved on the surface of the fourth damping rod 510. One end of the fifth spring 511 is fixedly connected to the top of the inner wall of the storage groove 509, and the end of the fifth spring 511 near the fourth damping rod 510 is fixedly connected to one side of the support block 512. When the connecting frame 501 is squeezed out of the coupling body 1, the fifth spring 511 squeezes the support block 512 away from the storage groove 509, thus supporting the connecting frame 501 through the support block 512. Fifth damping rods 506 are evenly fixedly connected to the top of the fixing plate 504. An L-shaped plate 508 is fixedly connected to the top of the coupling body 1. A sixth spring 507 is fitted onto the surface of the fifth damping rod 506. One end of the sixth spring 507 is fixedly connected to the top of the fixing plate 504. The end of the sixth spring 507 near the fifth damping rod 506 is fixedly connected to the bottom of one side of the L-shaped plate 508. A rubber rod 519 is slidably inserted through the end of the L-shaped plate 508 away from the fifth damping rod 506. One end of the rubber rod 519 is fixedly connected to one side of the coupling body 1. By pulling the L-shaped plate 508 towards the fixing plate 504 through the sixth spring 507, the L-shaped plate 508 is fitted onto the top of the coupling body 1, thus squeezing the rubber rod 519 into the interior of one side of the L-shaped plate 508. This facilitates the installation of the fixing plate 504.

[0037] 504 is confined to one side of the coupler body 1. A positioning frame 513 is fixedly connected to the top of the coupler body 1. A positioning strip 514 is slidably connected to the inner wall of the positioning frame 513. A groove 515 is formed on one side of the positioning strip 514. The inner wall of the groove 515 is slidably connected to one side of the L-shaped plate 508. A rubber strip 516 is fixedly connected to the inner wall of the groove 515. A sixth damping rod 517 is fixedly connected to one side of the inner wall of the positioning frame 513. The end of the sixth damping rod 517 away from the positioning frame 513 is fixedly connected to one end of the positioning strip 514. A seventh spring 518 is sleeved on the surface of the sixth damping rod 517. One end of the seventh spring 518 is fixedly connected to one side of the inner wall of the positioning frame 513. The end of the seventh spring 518 near the sixth damping rod 517 is fixedly connected to one side of the positioning strip 514. The seventh spring 518 is used to move the rod away from the positioning frame 513. The positioning strip 514 is pressed in the direction of the pressure, thereby pressing the L-shaped plate 508 into the interior of the groove 515, and pressing the rubber strip 516 onto the side of the L-shaped plate 508 away from the coupler body 1, thereby confining the L-shaped plate 508 inside the groove 515.

[0038] Working principle: When using the coupler, the coupler body 1 is connected to the line. The main functions of the high-frequency partial discharge signal coupler include signal capture, power monitoring and regulation, system protection, and impedance matching. In addition, the high-frequency partial discharge signal coupler also has the advantages of high sensitivity, wide bandwidth, and strong anti-interference ability, and can accurately capture the high-frequency current pulses generated by partial discharge. When using the fixing device 4, the fixing strip 417 is pulled towards the coupler body 1 by the third spring 420, so that the fixing strip 417 is positioned on the side of the rotating frame 402 away from the coupler body 1, and the rubber block 418 is pressed against one side of the rotating frame 402. This makes the rotating frame 402 away from the first connection port 2, which makes it easier to insert the connector 412 into the first connection port 2. Then, the connector 412 is manually inserted into the first connection port 2 by the first spring 407. The generated torque force drives the rotating frame 402 to rotate on one side of the rectangular bar 401, causing one end of the rotating frame 402 to press against the surface of the connecting sleeve 408. Then, the cylinder 403 is manually controlled to rotate on the surface of the rotating frame 402, thereby causing the arc plate 404 to be fitted onto the surface of the rubber cylinder 409, which in turn causes the protrusion 415 to press against the rubber cylinder 409. The surface of the curved plate 404 is covered to some extent to prevent the curved plate 404 from sliding on the surface of the connecting sleeve 408. The second spring 414 presses the sliding cylinder 411 away from the connector head 412, thereby fitting the sliding cylinder 411 onto the surface of the curved plate 404. This effectively restricts the curved plate 404 to the surface of the connecting sleeve 408, and to some extent restricts the connector head 412 inside the first connecting port 2. When using the connecting device 5, the fourth spring 503 presses the connecting frame 501 away from the coupler body 1, which facilitates the removal of parts inside the connecting frame 501 from the interior of the coupler body 1. After the connecting frame 501 is squeezed out of the coupler body 1, the fifth spring 511 presses the support block 512 away from the receiving groove 509, thus supporting the connecting frame 501. This facilitates the maintenance of the internal parts of the coupler body 1. After maintenance, the connecting frame 501 is slid into the interior of the coupler body 1. The L-shaped plate 508 is pulled towards the fixing plate 504 by the sixth spring 507, and then the L-shaped plate 508 is fitted onto the top of the coupler body 1. The positioning strip 514 is pressed away from the positioning frame 513 by the seventh spring 518, and then the L-shaped plate 508 is pressed into the interior of the groove 515. The rubber strip 516 is pressed into the side of the L-shaped plate 508 away from the coupler body 1, thus restricting the L-shaped plate 508 into the interior of the groove 515. The rubber rod 519 is pressed into the interior of one side of the L-shaped plate 508, thus restricting the fixing plate 504 to one side of the coupler body 1. The rubber plate 505 is pressed into the interior of the coupler body 1, thus allowing the parts to be stored.

[0039] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
