Description
Technical Field
[0001] This utility model relates to the field of power testing technology, and in particular to a DC withstand voltage burn-through generator. Background Technology
[0002] Power testing is defined as a series of detection, verification and analysis activities carried out on equipment and its overall performance in a power system. Among them, the DC withstand voltage burn-through generator is a device specifically designed to burn-through test the insulation defects of electrical equipment under DC high voltage conditions. This device can output a stable DC high voltage and burn through the weak points or defects in the insulation material by adjusting the current, thereby facilitating subsequent fault location and repair.
[0003] Because the high-voltage output lines of DC withstand voltage burn-through generators currently on the market generally lack automatic winding functions, users have to manually retract them after use. This process is not only tedious and time-consuming, but also, due to the manual winding method, the high-voltage output lines often become messy and even tangled. This not only affects the service life of the high-voltage output lines, but may also cause safety hazards in the next use. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the high voltage output line of the existing DC withstand voltage burn-through generator lacks an automatic winding function. Therefore, we propose a DC withstand voltage burn-through generator.
[0005] To achieve the above objectives, this application adopts the following technical solution: a DC withstand voltage burn-through generator, comprising a main body of the DC withstand voltage burn-through generator, an LCD screen mounted on the top of the main body, a controller mounted on the top of the main body, a trip switch mounted on the top of the main body, a wire groove formed inside the main body, limit plates fixedly connected to both sides of the wire groove, and a take-up roller rotatably connected inside the wire groove. Both ends of the take-up roller are equipped with take-up springs. A high-voltage output wire is wound around the surface of the take-up roller. A limit box is fixedly connected to the top of the wire groove. A movable groove is opened inside the limit box. A movable block is slidably connected inside the movable groove. A square groove is opened inside the movable block. Pressing blocks are slidably connected to both sides of the square groove. A limit block is fixedly connected to the bottom of the pressing block. Two clamping blocks are fixedly connected to one end of the movable block. Two limit grooves are opened on both sides of the movable groove. The surface of the limit block is slidably connected to the inside of the limit groove.
[0006] Preferably, a first sliding groove is provided on both sides of the movable groove, and a first slider is fixedly connected to both sides of the movable block, with the surface of the first slider slidably connected to the inside of the first sliding groove.
[0007] Preferably, a fixing plate is fixedly connected inside the square groove, and two first springs are fixedly connected to both sides of the fixing plate, with the other end of the first springs fixedly connected to the pressing block.
[0008] Preferably, the top of the pressing block is provided with a second sliding groove, and the top of the square groove is fixedly connected to a second slider, the surface of the second slider being slidably connected to the inside of the second sliding groove.
[0009] Preferably, an arc-shaped plate is fixedly connected to the surface of the limiting plate, a rotating rod is rotatably connected to the opposing surfaces of the arc-shaped plate, a sliding shaft is slidably connected to the surface of the rotating rod, a first connecting block is fixedly connected to the surface of the sliding shaft, two rollers are rotatably connected to the top of the first connecting block, and a second connecting block is fixedly connected to the top of the two rollers.
[0010] Preferably, a cleaning sponge is installed on the surface of the second connecting block, and the surface of the cleaning sponge is slidably connected to the surface of the high-voltage output line.
[0011] Preferably, the bottom end of the clamping block is equipped with an elastic anti-slip pad.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, pressing the pressing block causes it to move the limiting block out of the limiting groove. At this point, the movable block contacts the limiting block. Moving the movable block further causes the limiting block to enter another movable block.
[0014] The movable block moves the clamping block, releasing the clamping block's pressure on the high-voltage output line. At this point, the high-voltage output line can be pulled out to the required length. After pulling out the desired length, the movable block is reset, causing it to move the clamping block to limit and clamp the high-voltage output line. Moving the pressing block causes it to move the limiting block back into the limiting groove, limiting the movable block. After use, the clamping block is no longer clamping and limiting the high-voltage output line. By installing a winding spring at one end of the take-up roller, the take-up roller can automatically wind up the high-voltage output line. This feature allows the high-voltage output line to be automatically stored when not in use, preventing damage or inconvenience caused by scattered placement, ensuring the neatness and lifespan of the high-voltage output line. Furthermore, the automatic winding function greatly improves operating efficiency, allowing users to complete the finishing work of the equipment more quickly, thereby improving overall work efficiency and bringing convenience to users.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0024] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, this utility model provides a technical solution: a DC withstand voltage burn-through generator, including a DC withstand voltage burn-through generator body 1, a liquid crystal display screen 2 installed on the top of the DC withstand voltage burn-through generator body 1, a controller 3 installed on the top of the DC withstand voltage burn-through generator body 1, a disconnection switch 4 installed on the top of the DC withstand voltage burn-through generator body 1, a wire groove 5 opened inside the DC withstand voltage burn-through generator body 1, limit plates 6 fixedly connected to both sides of the wire groove 5, a take-up roller 7 rotatably connected inside the wire groove 5, a take-up spring 8 installed at both ends of the take-up roller 7, a high voltage output wire 9 wound on the surface of the take-up roller 7, a limit box 10 fixedly connected to the top of the wire groove 5, a movable groove 11 opened inside the limit box 10, a movable block 12 slidably connected inside the movable groove 11, a square groove 13 opened inside the movable block 12, pressing blocks 14 slidably connected to both sides of the square groove 13, a limit block 15 fixedly connected to the bottom of the pressing block 14, and the movable block 12 rotatably connected to the square groove 13. Two clamping blocks 16 are fixedly connected to one end of block 12. Two limiting grooves 17 are opened on both sides of the movable groove 11. The surface of the limiting block 15 is slidably connected to the inside of the limiting groove 17. By pressing the pressing block 14, the pressing block 14 drives the limiting block 15 to move out of the inside of the limiting groove 17. At this time, the movable block 12 contacts the limiting block. Then, the movable block 12 is moved so that the limiting block 15 enters the other movable block 12, causing the movable block 12 to drive the clamping block 16 to move, so that the clamping block 16 is aligned with the high voltage output line. Release the clamping force of 9. At this time, the high-voltage output line 9 can be pulled out according to the required length. After pulling out the required length, reset the movable block 12, so that the movable block 12 drives the clamping block 16 to limit and clamp the high-voltage output line 9. Move the pressing block 14, so that the pressing block 14 drives the limiting block 15 back into the limiting groove 17, so that the movable block 12 is limited. After use, the clamping block 16 is no longer clamping and limiting the high-voltage output line 9. This is achieved by installing a coil roller 7 at one end.
[0025] The winding spring 8 enables the take-up roller 7 to automatically wind up the high-voltage output wire 9. This feature allows the high-voltage output wire 9 to be automatically stored when not in use, preventing damage or inconvenience caused by its scattered placement. This ensures the neatness and lifespan of the high-voltage output wire 9. In addition, the automatic winding function greatly improves operating efficiency, allowing users to complete the finishing work of the equipment more quickly, thereby improving the overall work efficiency.

[0027] Reference Figure 5 and Figure 6As shown in this embodiment: the movable groove 11 has a first sliding groove 18 on both sides, and the movable block 12 has a first slider 19 fixedly connected to both sides. The surface of the first slider 19 is slidably connected to the inside of the first sliding groove 18. By moving the first slider 19 inside the first sliding groove 18, the movement of the movable block 12 can be made more stable, avoiding unnecessary tilting and shaking.
[0028] Reference Figure 6 As shown in this embodiment: a fixing plate 20 is fixedly connected inside the square groove 13. Two first springs 21 are fixedly connected to both sides of the fixing plate 20. The other end of the first spring 21 is fixedly connected to the pressing block 14. By setting the first spring 21, after the movable block 12 is reset, the elasticity of the first spring 21 will abut against the pressing block 14, so that the pressing block 14 drives the limiting block 15 to automatically enter the interior of the limiting groove 17. The user does not need to manually move the pressing block 14, which brings convenience to the user.
[0029] Reference Figure 6 As shown in this embodiment: the top of the pressing block 14 is provided with a second sliding groove 22, and the top of the square groove 13 is fixedly connected with a second slider 23. The surface of the second slider 23 is slidably connected to the inside of the second sliding groove 22. By setting the second slider 23 and the arc plate 24, the movement of the pressing block 14 can be guided, so that the pressing block 14 moves in a predetermined direction and prevents deviation.

[0032] Reference Figure 4 As shown in this embodiment: a cleaning sponge 30 is installed on the surface of the second connecting block 29. The surface of the cleaning sponge 30 is slidably connected to the surface of the high voltage output line 9. By setting the cleaning sponge 30 on the surface of the roller 28, the dust on the surface of the high voltage output line 9 can be cleaned, ensuring that the high voltage output line 9 will not accumulate dust on its surface during long-term use. At the same time, this design also reduces the frequency of manual cleaning and improves the maintenance efficiency of the equipment.
[0033] Reference Figure 5 As shown in this embodiment, an elastic anti-slip pad 31 is installed at the bottom end of the clamping block 16.
[0034] Working principle: By pressing the pressing block 14, the pressing block 14 moves the limiting block 15 out of the limiting groove 17. At this time, the movable block 12 contacts the limit. Moving the movable block 12 again causes the limiting block 15 to enter another movable block 12, causing the movable block 12 to move the pressing block 16, releasing the pressing block 16 from pressing the high-voltage output line 9. At this time, the high-voltage output line 9 can be pulled out according to the required length. After pulling out the required length, the movable block 12 is reset, causing the movable block 12 to move the pressing block 16 to limit and press the high-voltage output line 9. Moving the pressing block 14 causes the pressing block 14 to move the limiting block 15 back into the limiting groove 17, so that the movable block 12 is limited. After use, the pressing block 16 is no longer pressing and limiting the high-voltage output line 9. By installing a winding spring 8 at one end of the take-up roller 7, the take-up roller 7 can drive the high-voltage output line 9 to... Automatic winding allows the high-voltage output cable 9 to be automatically retracted when not in use, preventing damage or inconvenience caused by its scattered placement and ensuring the cleanliness and lifespan of the high-voltage output cable 9. Furthermore, the automatic winding function greatly improves operational efficiency, allowing users to complete the finishing work of the equipment more quickly, thereby improving overall work efficiency and bringing convenience to users. Moving the first slider 19 inside the first slide groove 18 makes the movement of the movable block 12 more stable, avoiding unnecessary tilting and shaking. The first spring 21, when the movable block 12 is reset, will abut against the pressing block 14, causing the pressing block 14 to automatically drive the limiting block 15 into the limiting groove 17, eliminating the need for manual movement of the pressing block 14 and providing convenience to users. The second slider 23 and the arc-shaped...
[0035] Plate 24 guides the movement of pressing block 14, ensuring it moves within a predetermined path and preventing deviation. Sliding shaft 26 on the surface of rotating rod 25 provides tension to the high-voltage output cable 9 during winding, making it tighter and less prone to loosening, further improving storage efficiency and operational stability. Cleaning sponge 30 on roller 28 removes dust from the surface of the high-voltage output cable 9, preventing dust accumulation during prolonged use. This design also reduces the frequency of manual cleaning, improving equipment maintenance efficiency. Elastic anti-slip pad 31 ensures more stable clamping and limiting of the high-voltage output cable 9, preventing loosening.
