[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) A rectangular frame is set on the upper side of the testing frame, and a matching groove is set on the opposite side of the rectangular frame. Multiple sets of connecting components are installed movably. When it is necessary to control the connection between the lower testing part and the terminal block, the connecting component near the end is driven by the cross frame to slide along the matching groove. The electric telescopic joint in the connecting component can adjust the position of the mounting block in the rectangular frame. In the initial stage, the multiple connecting components can be attracted together by the adsorption magnet set on the side of the mounting block. The cross frame and the electric telescopic joint are used to drive all the connecting components to move. After the testing part at the end of each connecting component is connected to the terminal block, the connecting component no longer moves synchronously with the cross frame. Through the above structure, the testing part in the testing mechanism is connected to each terminal of the high voltage transformer, thereby avoiding manual connection and effectively ensuring the reliability and safety of the terminal connection.

[0018] (2) After the terminal block and the detection head are connected, the pneumatic telescopic column drives the annular mating block to move along the inclined inner cavity, thereby causing the clamp to move towards the terminal block, thus ensuring a reliable connection between the clamp and the terminal block.

[0019] (3) The high-voltage transformer is fixed to the movable base by fixing bolts and fixing slots. The movable base, combined with the pulleys at the bottom, moves along the guide rail, thereby carrying the high-voltage transformer into the detection frame. During the movement of the movable base, the pulleys rotate with the motor, supporting the movable base so that it can be separated from the support base, thereby reducing the resistance between the movable base and the support base during the movement. When the movable base reaches the designated position, the pulleys are driven to rotate by the motor and the driving bevel gear, thereby causing the movable base to descend and come into contact with the support base, ensuring the stability of the movable base during the detection process.

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0033] like Figure 1 , Figure 2 As shown, a fully automatic high-voltage transformer error and excitation characteristic testing device for new energy includes a testing frame 1, a support base 10 is arranged parallel to the middle of the testing frame 1, a movable base 2 is installed on the guide rail 11, a high-voltage transformer is fixedly installed on the movable base 2, an adjustment mechanism 5 is arranged on the upper side of the testing frame 1, and the adjustment mechanism 5 is connected to a docking mechanism 4 and a testing mechanism 3.

[0034] like Figure 5 , Figure 6As shown, the testing mechanism 3 includes a testing frame 30, which is interlocked with the upper end of the high-voltage transformer. A rectangular frame 33 is provided on the upper edge of the testing frame 30, and a first sliding groove 34 is provided on opposite sides of the rectangular frame 33. Multiple sets of connecting components are slidably installed within the first sliding groove 34. Each connecting component includes a mounting block 310, with adsorption magnets on both sides of the mounting block 310. A snap-fit ​​slider 312 is slidably installed within the first sliding groove 34, and an expansion joint 311 is provided between the mounting block 310 and the snap-fit ​​slider 312. A docking motor 32 is provided at the bottom of block 310. The docking motor 32 is connected to a detection unit 313. The detection unit 313 cooperates with the wiring terminals of the high voltage transformer. A rack 35 is provided at the upper end of the rectangular frame 33 where a matching groove 34 is provided. A cross frame 36 is provided between the snap-fit ​​sliders 312 in a set of connecting components at the end. The telescopic joints 311 in this set of connecting components are electrically driven. A drive shaft is rotatably installed between the cross frames 36. Gears 37 are provided at both ends of the drive shaft. The gears 37 mesh with the rack 35.

[0035] Specifically, the high-voltage transformer is fixedly installed on the movable base 2, and the movable base 2 moves in and out of the detection frame 1 along the support base 10 in the middle of the detection frame 1. A rectangular frame 33 is set on the upper side of the testing frame 30, and a matching groove 34 is set on the opposite side of the rectangular frame 33. Multiple sets of connecting components are movably installed. When it is necessary to control the docking between the lower testing part 313 and the terminal block, the cross frame 36 drives a set of connecting components near the end to slide along the matching groove 34. The electric telescopic joint 311 in this set of connecting components can adjust the position of the mounting block 310 in the rectangular frame 33. In the initial stage, the multiple sets of connecting components can be attracted together by the adsorption magnets set on the side of the mounting block 310. The cross frame 36 and the electric telescopic joint 311 drive all connecting components to move. After the testing part 313 at the end of each connecting component docks with the terminal block, the connecting component no longer moves synchronously with the cross frame 36. Through the above structure, the testing part 313 in the testing mechanism 3 docks with each terminal block of the high voltage transformer, thereby avoiding manual docking and effectively ensuring the reliability and safety of the terminal connection.

[0036] Furthermore, such as Figure 7As shown, the detection unit 313 includes a detection head 3130, which is connected to a terminal block. A clamp 3134 is provided on the inner side of the detection head 3130 near the terminal block. The clamp 3134 is flexibly installed inside the detection head 3130. An inclined inner cavity 3131 is provided between the clamp 3134 and the detection head 3130. An annular mating block 3133 is provided in the inclined inner cavity 3131. Pneumatic telescopic columns 3132 are symmetrically arranged on the upper end of the detection head 3130. The pneumatic telescopic columns 3132 are connected to the annular mating blocks 3133.

[0037] Specifically, after the terminal block and the test head 3130 are connected, the pneumatic telescopic column 3132 drives the annular mating block 3133 to move along the inclined inner cavity 3131, thereby causing the clamp 3134 to move towards the terminal block, thus ensuring a reliable connection between the clamp 3134 and the terminal block. The clamp 3134 is electrically connected to the test instrument. When the clamp 3134 and the terminal block are reliably connected, the circuit between the high voltage transformer and the test equipment will be connected.

[0038] Furthermore, such as Figure 6 As shown, a second motor 39 is provided in the middle of the cross frame 36, and a bevel gear set 38 is provided between the second motor 39 and the drive shaft.

[0039] Furthermore, such as Figure 5 As shown, the docking mechanism 4 includes a suspended cross 40, a lifting cylinder 41 is provided at the bottom of the cross 40, and a plug-in post 31 is provided at the edge of the detection frame 30 corresponding to the end of the cross 40. The plug-in post 31 is plugged into the cross 40, and a connecting plate 42 is provided between the plug-in posts 31. The lifting cylinder 41 is provided between the connecting plate 42 and the cross 40.

[0040] Specifically, the testing frame 30 is connected to the cross 40 via the edge insertion post 31. Combined with the lifting cylinder 41, the testing frame 30 is raised and lowered, thereby controlling the bottom testing mechanism 3 to connect and cooperate with the upper end of the high voltage transformer, ensuring accurate connection between the subsequent testing mechanism 3 and the wiring terminal.

[0041] Furthermore, such as Figure 8 , Figure 9As shown, the adjustment mechanism 5 includes a suspension frame 50 set on the top of the detection frame 1. Two sets of snap-fit ​​grooves 51 are arranged in parallel inside the suspension frame 50. A rack 53 is set on the cross 40. A connecting frame 54 is set at the bottom of the suspension frame 50. A gear 56 is rotatably installed between the connecting frames 54. A motor 55 is connected to the gear 56. The gear 56 and the rack 53 mesh with each other. Snap-fit ​​posts 52 are fixedly set at both ends of the rack 53 on the cross 40. The upper end of the snap-fit ​​post 52 is slidably installed between the snap-fit ​​groove 51 and the suspension frame 50 is slidably installed with the detection frame 1.

[0042] Furthermore, such as Figure 8 , Figure 10 As shown, the top of the detection frame 1 is provided with a top frame 58, and a second matching groove 59 is provided in the top frame 58. A matching slider 510 is slidably installed in the second matching groove 59. A connecting rod 511 is fixedly provided between the matching slider 510 and the center of the suspension frame 50. A third rack 512 is provided on the edge of the second matching groove 59. A slot 513 is provided on the third rack 512. An L-shaped frame 514 is slidably installed in the slot 513. A fourth motor 515 is fixedly installed on the L-shaped frame 514. A fourth gear 516 is connected to the fourth motor 515. The axis of the fourth gear 516 is inserted into the matching slider 510.

[0043] Specifically, the adjustment mechanism 5 is used to adjust the position of the detection mechanism 3 relative to the high-voltage transformer. After the high-voltage transformer is placed on the movable seat 2, it is moved to the middle of the detection frame 1 by the support seat 10. The front and rear relative positions of the detection mechanism 3 are adjusted by the motor 3 55, the gear 3 56, and the rack 2 53. Then, the lateral position of the detection mechanism 3 is adjusted by the motor 4 515, the gear 4 516, and the rack 3 512 at the top, so as to realize the mutual docking between the detection mechanism 3 and the high-voltage transformer.

[0044] Among them, edge rods 57 are provided on both sides of the connecting frame 54. When the cross 40 moves relative to the suspension frame 50 with the locking post 52, the edge rods 57 are used to limit the movement distance of the cross 40 and prevent the gear 3 56 from disengaging from the rack 2 53.

[0045] Furthermore, such as Figure 11 As shown, the inner side of the testing frame 30 is provided with a mounting groove 300, and an abutment block 301 is slidably installed in the mounting groove 300. The bottom of the testing frame 30 near the high voltage transformer is provided with a rounded chamfer.

[0046] Specifically, in order to facilitate the docking of the test frame 30 with the upper side of the high voltage transformer, the bottom of the test frame 30 is provided with a rounded chamfer. At the same time, a mounting groove 300 and an abutment block 301 are provided on the inner side of the test frame 30. The mounting groove 300 and the abutment block 301 are used to limit the descent height of the test frame 30, ensuring that the test mechanism 3 has enough space to cooperate with the wiring terminals and to disengage after the test is completed.

[0047] Furthermore, such as Figure 3 , Figure 4 As shown, multiple sets of fixing slots 200 are arranged in parallel on the movable base 2. Fixing bolts 201 are installed in the fixing slots 200. The high-voltage transformer is fixedly connected to the movable base 2 through the fixing bolts 201. A guide rail 11 is provided on the support base 10. An installation shaft 22 is provided on the edge of the movable base 2. A pulley 21 is provided on the part of the installation shaft 22 corresponding to the guide rail 11. The pulley 21 and the guide rail 11 cooperate with each other. A driven bevel gear 23 is provided at the end of the installation shaft 22. A driving bevel gear 24 is rotatably installed in the movable base 2. The driven bevel gear 23 and the driving bevel gear 24 mesh with each other. The driving bevel gear 24 is connected to a motor 20. The motor 20 is fixedly installed between the movable base 2 and the motor 2.

[0048] Specifically, the high-voltage transformer is fixed to the movable base 2 by fixing bolts 201 and fixing grooves 200. The movable base 2, combined with the pulleys 21 at its bottom, moves along the guide rail 11, thereby carrying the high-voltage transformer into the detection frame 1. During the movement of the movable base 2, the pulleys 21 rotate with the motor 20, supporting the movable base 2 so that it can disengage from the support base 10, thereby reducing the resistance between the movable base 2 and the support base 10 during the movement. When the movable base 2 reaches the designated position, the motor 20, the driving bevel gear 24, and the driven bevel gear 23 drive the pulleys 21 to rotate, thereby causing the movable base 2 to descend and come into contact with the support base 10, ensuring the stability of the movable base 2 during the detection process.

[0049] Furthermore, such as Figure 7 As shown, the upper end of the terminal block is provided with an arc-shaped chamfer, and the bottom of the detection head 3130 is provided with a plurality of circumferential claws 3135, which are made of elastic material.

[0050] Specifically, the clamping claw 3135 ensures that the detection head 3130 and the top of the terminal block are properly aligned. Since the telescopic joints 311 in the connecting assembly with the crossbeam 36 are all non-powered, once the clamping claw 3135 engages with the top of the terminal block, adjacent connecting assemblies can be disengaged, allowing the next set of connecting assemblies to connect with the terminal block. The telescopic joints 311 in this set of connecting assemblies will adaptively adjust the position of the detection head 3130, ensuring proper alignment between the detection head 3130 and the top of the terminal block, effectively improving the connection efficiency of the terminal block. In contrast, the telescopic joints 311 in the connecting assembly with the crossbeam 36 are powered and can be electrically driven to adjust the position of the detection head 3130 relative to the terminal block.

[0051] The working principle of this invention embodiment is as follows:

[0052] like Figures 1-11As shown, the high voltage transformer is fixedly installed on the movable base 2, and the movable base 2 moves in and out of the detection frame 1 along the support base 10 in the middle of the detection frame 1. A rectangular frame 33 is set on the upper side of the testing frame 30, and a matching groove 34 is set on the opposite side of the rectangular frame 33. Multiple sets of connecting components are movably installed. When it is necessary to control the docking between the lower testing part 313 and the terminal block, the cross frame 36 drives a set of connecting components near the end to slide along the matching groove 34. The electric telescopic joint 311 in this set of connecting components can adjust the position of the mounting block 310 in the rectangular frame 33. In the initial stage, the multiple sets of connecting components can be attracted together by the adsorption magnets set on the side of the mounting block 310. The cross frame 36 and the electric telescopic joint 311 drive all connecting components to move. After the testing part 313 at the end of each connecting component docks with the terminal block, the connecting component no longer moves synchronously with the cross frame 36. Through the above structure, the testing part 313 in the testing mechanism 3 docks with each terminal block of the high voltage transformer, thereby avoiding manual docking and effectively ensuring the reliability and safety of the terminal connection. After the terminal block is connected to the test head 3130, the pneumatic telescopic column 3132 drives the annular mating block 3133 to move along the inclined inner cavity 3131, thereby causing the clamp 3134 to move towards the terminal block, thus ensuring a reliable connection between the clamp 3134 and the terminal block. The clamp 3134 is electrically connected to the test instrument. When the clamp 3134 and the terminal block are reliably connected, the circuit between the high voltage transformer and the test equipment will be connected. The clamping claw 3135 ensures that the detection head 3130 and the top of the terminal block are properly aligned. Since the telescopic joints 311 in the connecting assembly with the crossbeam 36 are all non-powered, once the clamping claw 3135 engages with the top of the terminal block, adjacent connecting assemblies can be disengaged, allowing the next set of connecting assemblies to connect with the terminal block. The telescopic joint 311 in this set of connecting assemblies will adaptively adjust the position of the detection head 3130, ensuring proper alignment between the detection head 3130 and the top of the terminal block, effectively improving the connection efficiency of the terminal block. In contrast, the telescopic joint 311 in the connecting assembly with the crossbeam 36 is powered and can be electrically driven to adjust the position of the detection head 3130 relative to the terminal block.
