Technical Field
[0001] This disclosure relates to the field of electrical equipment performance testing technology, and in particular to a comprehensive electrical equipment performance testing device. Background Technology
[0002] Comprehensive performance testing of electrical equipment is a critical testing process used to evaluate the safety, reliability, and functionality of electrical equipment. Its core objective is to ensure that the equipment can operate safely and stably under both normal and extreme conditions. This type of testing is widely used in the research, development, production, and quality control of products such as household appliances, power system equipment, motors, and transformers. Performance testing of electrical equipment mainly includes withstand voltage, insulation, grounding, voltage, current, leakage, power, and start-stop tests. Currently, the instruments used for these tests in the market are comprehensive test boxes. These test boxes have a cabinet structure, containing circuit and control modules related to the tests. The front of the box features a display, operation panel, and indicator lights. Depending on the needs of online and offline testing, comprehensive test boxes are typically configured as fixed or mobile units. Mobile comprehensive test boxes are often used for regular or routine on-site maintenance.
[0003] When using existing electrical equipment performance testing equipment, the device under test needs to be placed near the equipment and then connected via cables for multiple tests. During this process, because different devices are connected in different locations, the cables are easily tangled after testing, making them difficult to organize and store. At the same time, the efficiency of installing the device under test and conducting connection tests is low. Summary of the Invention

[0015] Optionally, a protruding plate is fixed to the top of the plug-in frame, and a third screw is threaded into the upper clamping plate at the position corresponding to the protruding plate, with a stop block rotatably connected to the bottom of the third screw.
[0016] The technical solution provided in this disclosure may include the following beneficial effects:
[0017] 1. In this invention, the first screw is driven to rotate by a motor, and the screw plate slides along the slide groove, which drives the positioning component and the clamping component to move along the slide table. During this process, the slip rings on both sides of the insertion frame slide along the guide rod and move upward from the bottom. The winding shafts at the top and bottom of the vertical frame wind and unwind the baffle through the torsion spring, which assists the movement of the insertion frame and keeps the insertion position of the insertion frame consistent with the insertion position of the test table after the insertion frame moves. The positioning component and the clamping component can be separated by a distance by an electric push rod, which makes it easier to find the insertion position of the front end of the device under test and facilitates subsequent cooperation with the positioning component to move the insertion position of the device under test to the insertion frame position and stop.
[0018] 2. In this invention, the plug-in frame eventually moves to a position flush with the mounting plate, thereby shortening the length of the connecting wire required for connection, reducing the inconvenience of subsequent cable retraction, and enabling faster installation and connection. Through the movement of the two back plates, the lower clamping plate slides along the upper end of the slide rail, and the belts of the three pulleys move through the outermost pulley. The two moving blocks slide along the slide rail, and the connecting rod drives the mounting base to move linearly, maintaining the transmission of the three pulleys. The limiting post ensures that the belt and pulley have sufficient wrapping and friction.
[0019] 3. This invention uses a motor to drive a bidirectional screw to rotate, and two vertical plates move along a horizontal groove. The distance between the two vertical plates is adjusted according to the width of the device under test. By rotating the knob of the pulley inside the mounting base, coupled with the belt drive, the pulleys at the bottom of the two fourth screws drive the fourth screws to rotate, causing the first telescopic plate to extend. The distance between the upper and lower clamping plates is adjusted to clamp and limit the height of the device under test. The back plate slides along the moving groove and is kept in pressure contact with the back of the device under test by the second spring. The front of the device under test is brought close to the insertion frame. The third screw is rotated, which moves the abutment block to the upper end of the insertion position of the device under test. Then, the motor drives the second screw to rotate, and the slide rail moves downward along the second screw and the first slide rod, causing the upper and lower clamping plates to clamp the device under test and slide along the vertical groove of the vertical plate. When the abutment block presses against the convex plate at the upper end of the insertion frame, it stops. At this time, the insertion position of the device under test corresponds exactly to the insertion frame, which facilitates connection and testing with the test bench.
[0020] 4. In this invention, when the positioning component moves along the slide table towards the test table, the sliding plates on both sides of the insertion frame slide along the vertical frame and slide along the guide rod via the slip ring. When it enters the straight rod position of the guide rod, the position of the push plate corresponds exactly to the second toothed plate. Subsequently, the positioning component continues to move, and the push plate presses the second toothed plate. The second toothed plate moves along the insertion rod direction and meshes with the gear. The gear meshes with the first toothed plate, causing the mounting plate to move towards the positioning component. At the same time, the front end of the connecting wire in the slider inside the mounting plate moves towards the insertion frame. The connecting wire slides along the second slide rod through the limiting frame, and is lengthened to facilitate connection with the connection end of the device under test inside the insertion frame. The other end of the connecting wire is originally stored inside the insertion socket. This insertion socket can be understood as a common rubber box, which stores and protects the connecting wire when not in use. At the same time, the third spring assists in the reset of the limiting plate, making it easy to retract the connecting wire for future use.

[0039] like Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown in the present disclosure, an embodiment of an electrical equipment performance comprehensive testing device is proposed, comprising: a test bench 1, a slide table 2 fixed at one end of the test bench 1, a clamping assembly 3 slidably mounted on the top of the slide table 2, a positioning assembly 4 provided at the front end of the clamping assembly 3, and a pull wire assembly 5 provided on the side of the test bench 1 facing the positioning assembly 4; the clamping assembly 3 includes vertical plates 31, the vertical plates 31 are provided in two sets, the inner sides of the two sets of vertical plates 31 are provided with two vertical grooves 317, and the top of the inner side of the vertical plates 31 is slidably mounted with an upper clamping plate 35 along the vertical groove 317, the bottom of the inner side of the vertical plates 31 is slidably mounted with a lower clamping plate 36 along the vertical groove 317, the lower clamping plate 36 is located inside the vertical groove 317 and a first telescopic plate 318 is fixedly mounted therein, and the extended end of the first telescopic plate 318 is fixedly connected to the upper clamping plate 35; the positioning assembly 4 includes vertical frames 41, the vertical frames 41 are provided in two sets, the two sets of vertical frames 41 are fixedly mounted on both sides of the top of the slide table 2, the two sets of vertical frames The internal sliding installation of the plug frame 411 is as follows: The pull wire assembly 5 includes a mounting plate 52, and multiple sliders 513 are slidably connected inside the mounting plate 52. A connecting wire 53 is snapped into the slider 513. The test platform 1 is located at the bottom of the mounting plate 52 and a plug seat 58 is fixed thereon. The other end of the connecting wire 53 is inserted and received inside the plug seat 58. This solution is mainly a test device for electrical performance. The connecting wire 53 is a cross-linked polyethylene insulated power cable and cable accessories. When using the device, the device under test is installed inside the clamping assembly 3. The clamping range of the clamping assembly 3 is adjusted according to the size of the device under test. The positioning assembly 4 and the clamping assembly 3 move along the slide table 2 to the test platform 1, and the plug end of the device under test is moved to the position of the plug frame 411 of the positioning assembly 4. The pull wire assembly 5 is passed through the plug frame 411 and connected to the plug position. The device under test is tested for withstand voltage, insulation, grounding, voltage, current, leakage, power, start and stop, etc. through the test platform 1.
[0040] like Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the positioning component 4 further includes: a first movable seat 45, a second movable seat 46, and an electric push rod 48. The first movable seat 45 is slidably sleeved on one end of the slide table 2 near the test table 1. The second movable seat 46 is slidably installed on the top of the test table 1 at the rear end of the first movable seat 45. The vertical frame 41 is fixed to the top of both sides of the first movable seat 45. The electric push rod 48 is fixed on both sides of the first movable seat 45, and the extended end of the electric push rod 48 is fixedly connected to the second movable seat 46. Among them, pulleys 47 are rotatably installed on both sides of the bottom of the first movable seat 45 and the second movable seat 46. The top of the slide table 2 is provided with three sets of sliding grooves 21. A first screw 22 is rotatably installed inside the middle sliding groove 21 of the slide table 2. A screw plate 23 is threaded onto the surface of the first screw 22. The bottom of the first movable seat 45 is fixedly connected to the screw plate 23.
[0041] Understandably, the first screw 22 is driven to rotate by the motor, and the screw plate 23 slides along the slide groove 21, which drives the positioning component 4 and the clamping component 3 to move along the slide table 2. During this process, the slip rings 44 on both sides of the insertion frame 411 slide along the guide rod 51 and move upward from the bottom. The winding shafts 413 at the top and bottom of the vertical frame 41 wind up and unwind the baffle 414 through the torsion spring, which assists the insertion frame 411 in moving and keeps the insertion position of the insertion frame 411 consistent with the insertion position of the test table 1 after it moves. The positioning component 4 and the clamping component 3 can be separated by a distance by the electric push rod 48, which makes it easier to find the insertion position of the front end of the device under test and facilitates subsequent cooperation with the positioning component 4 to move the insertion position of the device under test to the position of the insertion frame 411 and stop.
[0042] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, in some embodiments, the top of the second movable seat 46 is provided with a horizontal groove 49, and a bidirectional screw 410 is rotatably installed inside the horizontal groove 49. The bottom of the vertical plate 31 is threaded onto the surface of the bidirectional screw 410. Two second telescopic plates 415 are symmetrically slidably installed inside the insertion frame 411, and the receiving end of the second telescopic plate 415 is slidably installed on the outer surface of the vertical plate 31. The top and bottom of the two sets of vertical frames 41 are rotatably mounted with a winding shaft 413 via a rotating shaft and a torsion spring. A baffle 414 is wound onto the winding shaft 413. The baffle 414 is fixedly connected to the top and bottom of the insertion frame 411. The clamping assembly 3: back... The system comprises a plate 314, a movable groove 315, and a fourth screw 319. Movable grooves 315 are formed on the bottom surface of the upper clamping plate 35 and the top surface of the lower clamping plate 36. A back plate 314 is slidably installed inside the movable groove 315. A fourth screw 319 is rotatably installed on the receiving end surface of a first telescopic plate 318 on one side of the back plate 314, with the bottom of the extended end of the first telescopic plate 318 threaded onto the surface of the fourth screw 319. A second spring 316 is fixed between the inner wall of the movable groove 315 and the back plate 314. A slide rail 32 is slidably connected to the side of the lower clamping plate 36 away from the test bench 1. Two movable blocks 311 are symmetrically slidably connected inside the slide rail 32. A first spring 310 is fixed to one end of the movable block 311 and the slide rail 32. A connecting rod 312 is rotatably connected to the outer surface of the movable block 311. The other ends of the two connecting rods 312 are rotatably connected to the mounting base 39. Pulleys 313 are rotatably installed inside the lower clamping plate 36 corresponding to the fourth screw 319 and the mounting base 39. The bottom of the fourth screw 319 is fixedly connected to the pulleys 313. A belt is sleeved on the outer surface of the three pulleys 313. Limiting posts are fixed to the two ends of the mounting base 39 and the lower clamping plate 36 corresponding to the belts of the pulleys 313. The second movable seat 46 is located at one end of the slide rail 32 and a second screw 33 is rotatably installed thereon. One end of the slide rail 32 is threaded onto the surface of the second screw 33. The second movable seat 46 is located at the other end of the slide rail 32 and is fixed with the first slide rod 34. The other end of the slide rail 32 is slidably sleeved on the first slide rod 34. The top of the plug frame 411 is fixed with a protruding plate 412. The upper clamping plate 35 is threadedly inserted with a third screw 37 at the position corresponding to the protruding plate 412. The bottom of the third screw 37 is rotatably connected with a stop block 38. In this solution, the equipment to be tested and clamped can be intelligent large-scale DC converter transformers, intelligent reactors, and other transformers, rectifiers, and inductors. After manufacturing, comprehensive performance testing is performed. It can also be used in the manufacturing of power distribution switch control equipment such as facilities.
[0043] Understandably, the motor drives the bidirectional screw 410 to rotate, and the two vertical plates 31 move along the horizontal groove 49. The distance between the two vertical plates 31 is adjusted according to the width of the device under test. By rotating the knob of the pulley 313 inside the mounting base 39, coupled with belt transmission, the pulleys 313 at the bottom of the two fourth screws 319 drive the fourth screws 319 to rotate, causing the first telescopic plate 318 to extend. The distance between the upper clamping plate 35 and the lower clamping plate 36 is adjusted to clamp and limit the height of the device under test. The back plate 314 slides along the moving groove 315, maintaining contact with the back of the device under test via the second spring 316. The front of the device under test is positioned close to the insertion frame 411. The third screw 37 is rotated, causing the abutment block 38 to move to the upper end of the insertion position of the device under test. Subsequently, the motor drives the second screw 33 to rotate, and the slide rail 32 moves downward along the second screw 33 and the first slide rod 34, causing the upper clamping plate 35 and the lower... The clamping plate 36 holds the device under test and slides along the vertical groove 317 of the vertical plate 31. It stops when the abutment block 38 presses against the protruding plate 412 at the upper end of the plug frame 411. At this time, the plug position of the device under test corresponds to the plug frame 411, which facilitates connection and testing with the test bench 1. In this way, because the plug frame 411 will eventually move to a position flush with the mounting plate 52, the length of the connecting wire 53 required for connection is shortened, thereby reducing the inconvenience of subsequent cable retraction and enabling faster installation and connection. Through the movement of the two back plates 314, the lower clamping plate 36 slides along the upper end of the slide rail 32, and the belts of the three pulleys 313 move through the outermost pulley 313. The two moving blocks 311 slide along the slide rail 32, and the connecting rod 312 drives the mounting base 39 to move linearly, maintaining the transmission of the three pulleys 313. The limiting post ensures that the belt and pulleys 313 have sufficient wrapping and friction.
[0044] like Figure 3 and Figure 4As shown, in some embodiments, the pull wire assembly 5 further includes: a guide rod 51 and a fourth spring 57. The guide rod 51 is slidably inserted into both ends of the mounting plate 52. The guide rod 51 includes a straight rod and an inclined rod. One end of the straight rod of the guide rod 51 is fixedly connected to the test bench 1, and the bottom of the inclined rod of the guide rod 51 is fixedly connected to both sides of the slide table 2. Slide plates 42 are fixed to both ends of the insertion frame 411. A slip ring 44 is rotatably connected to the outer side of the slide plate 42, and the slip ring 44 is slidably sleeved on the guide rod 51. A fourth spring 57 is sleeved on the guide rod 51 between the mounting plate 52 and the test bench 1. Both ends of the fourth spring 57 are fixedly connected to the mounting plate 52 and the test bench 1. A gear 59 is rotatably installed on the guide rod 51 between the mounting plate 52 and the vertical frame 41. The bottom of the gear 59 is meshed with a first... A toothed plate 510 is fixedly connected to a mounting plate 52. A second toothed plate 511 is meshed with the top of a gear 59. A plug rod 512 is fixedly attached to the mounting plate 52 at a position corresponding to the second toothed plate 511, and the plug rod 512 is slidably inserted into the inside of the second toothed plate 511. A push plate 43 is fixedly attached to the outer side of the slide plate 42 at a position corresponding to the second toothed plate 511. A limiting plate 54 is provided on the top of the test platform 1 between the plug-in seat 58 and the mounting plate 52. A second slide rod 55 is slidably inserted into both ends of the limiting plate 54. The bottom of the second slide rod 55 is fixedly connected to the test platform 1. A connecting line 53 slides through the limiting plate 54. A third spring 56 is sleeved on the surface of the second slide rod 55 at the bottom of the limiting plate 54, and both ends of the third spring 56 are fixedly connected to the test platform 1 and the limiting plate 54.
[0045] It should be noted that when the positioning component 4 moves along the slide table 2 towards the test table 1, the slide plates 42 on both sides of the insertion frame 411 slide along the vertical frame 41 and slide along the guide rod 51 via the slip ring 44. When it enters the straight rod position of the guide rod 51, the position of the push plate 43 corresponds exactly to the second toothed plate 511. Then the positioning component 4 continues to move, and the push plate 43 presses the second toothed plate 511. The second toothed plate 511 moves along the direction of the insertion rod 512 and meshes with the gear 59. The gear 59 meshes with the first toothed plate 510, causing the mounting plate 52 to move toward the positioning component 4. At the same time, the front end of the connecting line 53 in the slider 513 inside the mounting plate 52 moves toward the insertion frame. As frame 411 moves, connecting wire 53 slides along the second slide bar 55 via the limiting bracket, extending to facilitate connection with the device under test (DUT) inside the plug-in frame 411. The other end of connecting wire 53 is originally stored inside the plug socket 58, which can be understood as a common rubber-wrapped box. When not in use, it stores and protects connecting wire 53. At the same time, the third spring 56 assists in the reset of the limiting plate 54, making it easy to retract connecting wire 53 for future use. In this solution, the connecting wire 53 is specifically used to connect the DUT to the test bench 1 to perform tests such as withstand voltage, insulation, grounding, voltage, current, leakage, power, and start / stop.
[0046] Working principle:
[0047] When using the device, the device under test is installed inside the clamping assembly 3. The bidirectional screw 410 is driven to rotate by the motor, and the two vertical plates 31 move along the horizontal groove 49. The distance between the two vertical plates 31 is adjusted according to the width of the device under test. By rotating the knob of the pulley 313 inside the mounting base 39, coupled with the belt drive, the pulleys 313 at the bottom of the two fourth screws 319 drive the fourth screws 319 to rotate, causing the first telescopic plate 318 to extend. The distance between the upper clamping plate 35 and the lower clamping plate 36 is adjusted to clamp and limit the height of the device under test. The back plate 314 slides along the moving groove 315 and is kept in pressure contact with the back of the device under test by the second spring 316. The front of the device under test is placed close to the insertion frame 411, and the third screw 37 is rotated. The abutment 38 is moved to the upper end of the insertion position of the device under test. Then, the second screw 33 is rotated by the motor, and the slide rail 32 moves downward along the second screw 33 and the first slide rod 34, causing the upper clamping plate 35 and the lower clamping plate 36 to hold the device under test and slide along the vertical groove 317 of the vertical plate 31. When the abutment 38 comes into contact with the protrusion 412 at the upper end of the insertion frame 411, it stops. At this time, the insertion position of the device under test corresponds exactly to the insertion frame 411, which facilitates connection and testing with the test bench 1. In this way, because the insertion frame 411 will eventually move to a position flush with the mounting plate 52, the length of the connecting wire 53 required for connection is shortened, thereby reducing the inconvenience of subsequent cable retraction and enabling faster installation and connection. The movement of the two back plates 314 causes the lower clamping plate 36 to slide along the upper end of the slide rail 32, and the belts of the three pulleys 313 move through the outermost pulley 313. The two moving blocks 311 slide along the slide rail 32, and the connecting rod 312 drives the mounting base 39 to move linearly, maintaining the transmission of the three pulleys 313. The limiting post ensures that the belt and pulleys 313 have sufficient wrapping and friction. The sliding plates 42 on both sides of the insertion frame 411 slide along the vertical frame 41 and slide along the guide rod 51 through the slip ring 44. When it enters the straight rod position of the guide rod 51, the position of the push plate 43 corresponds exactly to the second toothed plate 511. Then the positioning component 4 continues to move, pressing the second toothed plate 511 through the push plate 43. The second toothed plate 511 moves along the direction of the insertion rod 512. Engaging with gear 59, which in turn engages with the first toothed plate 510, the mounting plate 52 moves toward the positioning assembly 4. Simultaneously, the front end of the connecting wire 53 in the slider 513 within the mounting plate 52 moves toward the insertion frame 411. The connecting wire 53 slides along the second slide rod 55 via a limiting bracket, extending to facilitate connection with the device under test (DUT) inside the insertion frame 411. The other end of the connecting wire 53 is originally stored inside the insertion socket 58, which can be understood as a common rubber-wrapped box. When not in use, it stores and protects the connecting wire 53. A third spring 56 assists in the reset of the limiting plate 54, facilitating the retraction of the connecting wire 53 for future use. In this design, the connecting wire 53 is specifically designed for connecting the DUT to the test bench 1.This allows for the performance of tests including withstand voltage, insulation, grounding, voltage, current, leakage, power, and start / stop. The motor drives the first screw 22 to rotate, causing the screw plate 23 to slide along the slide groove 21, which in turn moves the positioning assembly 4 and the clamping assembly 3 along the slide table 2. During this process, the slip rings 44 on both sides of the insertion frame 411 slide along the guide rod 51, moving upwards from the bottom. The winding shafts 413 at the top and bottom of the vertical frame 41 use torsion springs to wind and unwind the baffle 414, assisting the movement of the insertion frame 411 and ensuring that the insertion frame 411 is aligned with the insertion position on the test bench 1. An electric push rod 48 can separate the positioning assembly 4 and the clamping assembly 3 by a certain distance, facilitating the location of the insertion position at the front of the device under test. This allows for subsequent coordination with the positioning assembly 4, moving the insertion position of the device under test precisely to the position of the insertion frame 411. The test bench 1 then performs withstand voltage, insulation, grounding, voltage, current, leakage, power, and start / stop tests on the device under test.
