Description

Technical Field

[0001] This invention relates to the field of power testing technology, and in particular to an auxiliary device for performance testing of primary equipment in substations. Background Technology

[0002] In power systems, the insulation performance and operating status of primary equipment in substations, such as power transformers, circuit breakers, disconnect switches, voltage transformers, and current transformers, directly determine the safety and stability of the power grid. Therefore, it is necessary to periodically conduct high-voltage withstand voltage tests and other electrical performance tests on the primary equipment in substations. In traditional performance testing, testers typically need to securely connect the high-voltage withstand voltage test leads to the terminals of the primary equipment located at a height. Since substation primary equipment is usually installed on high supports or platforms, the installation and removal of test leads must be performed by testers working at height.

[0003] In existing performance tests of primary equipment in substations, the complex environment and numerous high-voltage electrical devices within the substation present significant challenges. Personnel climbing above bushings to manually connect and disconnect test leads pose a substantial risk of fall and accidental contact with live parts due to insufficient safety distance. Furthermore, manual wiring cannot provide sufficient clamping force, resulting in unreliable wiring strength and distorted performance tests. Additionally, the varying orientations of primary equipment terminals hinder flexible wiring operations. Summary of the Invention

[0010] In one embodiment of the present invention, the driver includes a mounting socket for docking a transmission joint, and multiple docking posts are provided on both sides of the clamp; it also includes a rotary drive mechanism for driving the clamp to rotate and dock the power output end of the driver, the rotary drive mechanism including: a mounting base; a lifting assembly, the lifting assembly being mounted on the mounting base, the power output end of the lifting assembly being detachably connected to the docking post; and a rotary transmission assembly, the rotary transmission assembly being mounted on the power output end of the lifting assembly, the power output end of the rotary transmission assembly being connected to the lifting assembly; wherein, after the lifting assembly drives the clamp to move upward away from the mounting socket, the clamp, under the elastic force of the rotary transmission assembly, causes the transmission joint to reach the initial position. When the initial position does not meet the usage requirements, the lifting assembly continues to drive the rotary transmission assembly, causing the clamp to move upward and flip simultaneously to replace the transmission joint, positioning and clamping the primary equipment terminal, and after the positioning and clamping is completed, the lifting assembly leaves the docking post while performing circumferential docking self-locking.

[0011] In one embodiment of the present invention, the lifting assembly includes: a rotating shaft located on both sides of the clamp; a lifting seat, one end of a set of rotating shafts being rotatably mounted on a corresponding lifting seat, and the lower end of the lifting seat being slidably inserted into the mounting base; and a lifting drive, the lifting drive being mounted on the mounting base, one end of another set of rotating shafts being rotatably connected to the corresponding lifting seat and a rotating transmission assembly, and the power output end of the lifting drive being connected to the bottom of the corresponding lifting seat; a chuck, the chuck being slidably inserted on a corresponding rotating shaft, and the chuck having a docking hole corresponding to a docking post; a locking disc, the locking disc being located between the chuck and the lifting seat, the locking disc being mounted on one side of the lifting seat, and the locking disc having a locking post corresponding to the docking hole; a traction rod, one end of each traction rod being connected to a corresponding chuck; and a locking drive, the locking drive being rotatably mounted on the lifting seat, and the other end of each traction rod being connected to the power output end of the locking drive, so as to drive the chuck connected to the traction rod to move simultaneously toward the corresponding docking post to complete the docking, and to position and clamp the primary equipment terminal block. After the positioning and clamping are completed, the chuck moves simultaneously toward the corresponding locking post to self-lock the circumferential docking position.

Located on one side of the transmission gear, the extended end of the rotating shaft is inserted into the drive guide mechanism; and a toothed plate, the top of which is elastically slidably mounted on the drive guide mechanism; wherein, after the rotating shaft moves upward away from the mounting socket, the transmission gear rotates under the elastic force of the second elastic element, causing the limiting rod to reach one end of the limiting groove, and the transmission joint to reach the initial position. When the initial position does not meet the usage requirements, the rotating shaft continues to move upward, and the extended end of the rotating shaft, under the guidance of the drive guide mechanism, causes the transmission gear to mesh with the toothed plate, causing the clamp to flip and switch the transmission joint. When the switching is completed, the drive guide mechanism causes the first locking tooth to contact and lock on the second locking tooth, and drives the switched transmission joint to be inserted into the mounting socket for docking and locking through the lifting drive.

[0013] In one embodiment of the present invention, the drive guide rail mechanism includes: a guide base mounted on a mounting base; a track plate slidably disposed on the guide base, the track plate having an annular guide rail, the top end of the annular guide rail having an inner elastically inserted first limiting block, the lower end of the annular guide rail having an inner elastically inserted second limiting block, and the protruding end of the rotating shaft being inserted into the annular guide rail; and a pad strip, the pad strip being installed on one side of the track plate, and the pad strip corresponding to the side surface of the transmission gear, the pad strip being located on the side away from the toothed plate, and the top side of the pad strip having a ramp surface corresponding to the transmission gear; wherein, after the transmission gear rotates on the toothed plate to cause the transmission joint to rotate and change, the transmission gear pushes the toothed plate to continue moving upward, causing the transmission gear to contact the pad strip, the transmission gear moves towards the lifting seat side, and after the first locking tooth and the second locking tooth lock, the protruding end of the rotating shaft moves downward along the other side of the annular guide rail to the lowest point, so that the rotated transmission joint is connected to the mounting socket.

The clamp positions and holds the substation primary equipment terminals, achieving electrical connection between the clamp and the grounding wire mounting post, thus enabling circuit conduction and completing various performance tests. When the clamp reaches the primary equipment terminals, a camera unit can capture images of the terminal layout.

[0032] Please see Figures 1 to 14 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

[0033] Please see Figure 1 , Figure 2 , Figure 8 and Figure 9 This invention provides an auxiliary device for performance testing of primary equipment in a substation, comprising: an operating lever 1; a driver 2, the driver 2 being mounted on the top of the operating lever 1; a clamp 3, the clamp 3 including a transmission mechanism 31, a clamping plate 32, and multiple transmission joints 33, the transmission mechanism 31 including multiple transmission input ends 313, each transmission input end 313 being correspondingly inserted into a transmission joint 33, the transmission joint 33 and the clamping plate 32 being mounted on the transmission mechanism 31; a grounding wire mounting post 4, the grounding wire mounting post 4 being located on one side of the transmission mechanism 31, and the grounding wire mounting post 4 being electrically connected to the clamping plate 32; and a camera unit 5, the camera unit 5 being mounted on one side of the driver 2, used to acquire images of the clamping process of the primary equipment terminals; wherein, according to the wiring direction of the primary equipment terminals in the captured images, the corresponding transmission joint 33 is adjusted to align with the power output end of the driver 2, so that the clamping direction of the clamping plate 32 corresponds to the wiring direction, and the clamp 3 is released after the primary equipment terminals are positioned and clamped by the transmission mechanism 31 to conduct the test.

[0034] As can be seen from the above, during high-voltage withstand voltage tests and other electrical performance tests on primary equipment in substations, such as power transformers, circuit breakers, disconnect switches, voltage transformers, and current transformers, the test personnel can connect the high-voltage withstand voltage test lead to the grounding wire mounting post 4. By holding the operating lever 1, the personnel can lift and move the driver 2 and the clamp 3 connected to the power output terminal of the driver 2 to the substation primary equipment side on a high support or platform. The clamp 3 is used to position and clamp the wiring terminals of the substation primary equipment, and the clamp 3 is used to achieve electrical connection with the grounding wire mounting post 4, thereby achieving circuit conduction and completing various performance tests. Specifically, when the clamp 3 reaches the primary equipment terminal, the camera unit 5 can capture images of the arrangement of the primary equipment terminal. Based on the wiring direction of the primary equipment terminal in the captured image, the corresponding transmission connector 33 can be selected to connect with the power output terminal of the driver 2. After the connection is completed, the primary equipment terminal is positioned and clamped by the clamping plate 32 corresponding to the wiring direction. After positioning and clamping, the clamp 3 is released, and the clamp connected by the high voltage withstand voltage test wire is used to clamp the primary equipment terminal separately for performance testing. This improves the convenience and safety of the performance testing of the transformer primary equipment, replaces the traditional climbing operation, and eliminates the safety risks of personnel falling from heights and high voltage electric shock.

[0035] It is worth noting that the clamping plate 32 and the grounding wire mounting post 4 can be electrically connected via a wire. Of course, electrical connections can also be made in other directions, such as when both the clamping plate 32 and the transmission mechanism 31 are conductor structures.

[0036] like Figure 3 and Figure 4As shown, the driver 2 may further include: a drive motor 21, which is mounted on the top of the operating lever 1; a mounting socket 22, which is mounted on the top of the drive motor 21, and the top of the mounting socket 22 is detachably snap-fitted to the transmission joint 33, with a shaft hole 221 in the middle of the mounting socket 22; and a drive terminal 23, with a limiting ring 231 on its side wall, which is rotatably engaged in the shaft hole 221. The lower end of the drive terminal 23 is slidably sleeved with the power output end of the drive motor 21 along its axial direction, and the upper end of the drive terminal 23 extends out of the shaft hole. The top of 221 is for docking with the transmission connector 33; and the first elastic member 24 is located between the top of the drive motor 21 and the bottom of the limiting ring 231, and the first elastic member 24 is located in the mounting socket 22; wherein, when the transmission input end 313 and the drive terminal 23 are not in a corresponding state, when the drive motor 21 drives the drive terminal 23, which moves downward along the power output end of the drive motor 21, to rotate to a position corresponding to the transmission input end 313, the drive terminal 23 is moved upward by the elastic force of the first elastic member 24 and is locked with the transmission input end 313.

[0037] When the driver 2 is connected to the corresponding transmission input end 313 of the transmission mechanism 31, the transmission connector 33 can be installed on the mounting socket 22. Then, by controlling the drive motor 21 to rotate, its power output end rotates the drive terminal 23, while the limiting ring 231 guides the rotation of the drive terminal 23 in the shaft hole 221. When the transmission connector 33 is inserted into the mounting socket 22, in the initial state, the drive terminal 23 moves downward, and the first elastic element 24 is in a compressed state. As the drive motor 21 drives the drive terminal 23 to rotate, the top of the drive terminal 23 and the transmission input end 313 at the bottom of the transmission connector 33 are engaged. Specifically, the top of the drive terminal 23 can be a protrusion, and the transmission input end 313 at the bottom of the transmission connector 33 can be a groove corresponding to the protrusion. When the rotation position corresponds, the elastic force of the first elastic element 24 triggers the protrusion to move upward and insert into the groove, achieving engagement. Alternatively, the top of the drive terminal 23 can be a groove, and the transmission input end 313 at the bottom of the transmission connector 33 can be a protrusion corresponding to the groove. The first elastic element 24 can be a spring, or other elastic energy storage components. The drive motor 21 can be a servo motor, or other rotary drive.

[0038] When the transmission joint 33 is installed on the power output end of the driver 2, a manual switching method can be used to change the clamping direction of the clamping plate 32 on the primary equipment terminal block. Of course, for the convenience of high-altitude use, the clamp 3 can also be automatically rotated at high altitude by the rotary drive mechanism 6 to adjust the clamping direction of the clamping plate 32 on the primary equipment terminal block to correspond with the wiring direction of the primary equipment terminal block.

[0039] In the substation primary equipment performance testing auxiliary device of the present invention, if the transmission joint 33 and the mounting socket 22 are assembled manually, it is necessary to ensure that the transmission joint 33 can be portablely connected and installed with the mounting socket 22.

[0040] like Figure 5 As shown, the side wall of the transmission joint 33 may be provided with a rotating snap-fit ​​groove 331.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the mounting socket 22 may further include: a mounting sleeve 222, the lower end of which is mounted on the top of the drive motor 21, and the top of the mounting sleeve 222 is provided with a locking space corresponding to the limiting ring 231; and a claw seat 223, which is mounted on the top of the mounting sleeve 222 to limit the limiting ring 231 within the locking space, and the edge of the claw seat 223 extends upward with a plurality of locking claw heads 224 to be rotatably connected to the transmission joint 33 along the rotating snap-fit ​​groove 331.

[0042] When manually assembling the transmission connector 33 with the mounting socket 22, the locking claw head 224 can be inserted along the entrance of the rotating snap groove 331 on one side of the bottom of the mounting socket 22, and then tightened so that the bottom of the transmission connector 33 is close to the upper surface of the protruding claw seat 223, and the transmission input end 313 at the bottom of the transmission connector 33 corresponds to the drive terminal 23 on the surface of the protruding claw seat 223, and then the locking and docking installation is completed.

[0043] like Figure 5The rotating snap-fit ​​groove 331 may include a sliding groove 3311 and a locking groove 3312. The sliding groove 3311 extends to the bottom of the transmission joint 33, and the locking groove 3312 is located on the side wall of the transmission joint 33 and communicates with the sliding groove 3311. A locking step is provided at the connection between the locking groove 3312 and the sliding groove 3311. The locking claw 224 can slide along the sliding groove 3311, pass over the locking step, and enter the locking groove 3312 to realize the manual assembly of the transmission joint 33 and the mounting socket 22 according to the wiring direction of the primary equipment terminal. The clamping direction of the clamping plate 32 corresponds to the wiring direction of the primary equipment terminal. After the equipment terminal is positioned and clamped, the locking claw 224 leaves the transmission joint 33 along the rotating snap-fit ​​groove 331 by rotating the operating lever 1 in the opposite direction, so that the test can continue through the clamping fixture 3.

[0044] like Figures 5 to 7 As shown, to clamp the terminals of the primary equipment, the clamping plate 32 includes two clamping plates. Specifically, the clamping plate 32 may include an upper clamping plate 321 and a lower clamping plate 322. The transmission mechanism 31 may include: a guard arm 311, with the upper clamping plate 321 mounted on the top of the guard arm 311 and the lower clamping plate 322 slidably disposed within the guard arm 311; and a lifting transmission assembly 312, which is mounted on the inner side of the guard arm 311, and the power output end of the lifting transmission assembly 312 is connected to the lower clamping plate 322; wherein, the transmission joint 33 is mounted on the bottom and one side of the guard arm 311, and the corresponding transmission input end 313 is correspondingly disposed on the bottom and one side of the lifting transmission assembly 312.

[0045] In the connection between the clamping plate 32 and the transmission mechanism 31, the upper clamping plate 321 can be fixedly installed on the top of the guard arm 311, and the lower clamping plate 322 can be inserted into the slide rail inside the guard arm 311. Thus, the lifting transmission assembly 312 can be driven by the drive motor 21, thereby driving the lower clamping plate 322 to move towards the upper clamping plate 321 along the clamping direction, thereby achieving the clamping force of the lower clamping plate 322 and the upper clamping plate 321 to clamp the primary equipment terminal.

[0046] In addition, a guide cylinder 332 for inserting the transmission joint 33 is fixed at the bottom and one side of the guard arm 311. A bearing 333 for rotating and positioning the first transmission terminal 3122 or the second transmission terminal is installed in the guide cylinder 332 to ensure the stability of the transmission between the first transmission terminal 3122 and the second transmission terminal.

[0047] like Figure 6 and Figure 7As shown, the lifting transmission assembly 312 includes: a transmission screw 3121, the upper end of which is rotatably inserted into the bottom of the upper clamping plate 321, and the lower end of which extends through a set of transmission joints 33 located at the bottom of the guard arm 311, with a first transmission terminal 3122 at the lower end of the transmission screw 3121; a first helical gear 3123 mounted on the transmission screw 3121; a second helical gear 3124 arranged in a direction perpendicular to the axial direction of the transmission screw 3121, with the second helical gear 3124 engaging with the first helical gear 3123; and a transmission rod 3125, the first end of which extends through another set of transmission joints 33 located on one side of the guard arm 311, with a second transmission terminal at the first end of the transmission rod 3125, and the second end of the transmission rod 3125 connected to the second helical gear 3124.

[0048] In the process of transmitting power from the drive motor 21 to the lower clamping plate 322, when the first transmission terminal 3122 is connected to the drive terminal 23, the drive motor 21 can directly drive the transmission screw 3121 to rotate, thereby causing the lower clamping plate 322 to move back and forth along the slide rail inside the guard arm 311, changing the distance between the lower clamping plate 322 and the upper clamping plate 321, thus enabling the clamping plate 32 to clamp or release the primary equipment wiring terminals. When the second transmission terminal is connected to the drive terminal 23, the drive motor 21 can drive the transmission rod 3125 and the second helical gear 3124 to rotate, and the second helical gear 3124 transmits power to the first helical gear 3123, causing the transmission screw 3121 to rotate, thereby causing the lower clamping plate 322 to move back and forth along the slide rail inside the guard arm 311, changing the distance between the lower clamping plate 322 and the upper clamping plate 321, thus enabling the clamping plate 32 to clamp or release the primary equipment wiring terminals.

[0049] In the substation primary equipment performance testing auxiliary device of the present invention, when assembling the transmission joint 33 and the mounting socket 22 using an automatic docking method, the same structure as the aforementioned driver 2, transmission mechanism 31, clamping plate 32, and transmission joint 33 can be adopted, so that the automatic docking of the transmission joint 33 and the driver 2 in the air can be achieved by rotating the drive mechanism 6. In addition, in order to ensure the positioning effect of the transmission joint 33 after docking, the mounting socket 22 of the driver 2 can be designed as an elastic telescopic structure.

[0050] like Figure 14As shown, the mounting socket 22 may also include: a mounting sleeve 222, the lower end of which is mounted on the top of the drive motor 21, and the top of the mounting sleeve 222 is provided with a locking space corresponding to the limiting ring 231; and a claw seat 223, which is mounted on the top of the mounting sleeve 222 to limit the limiting ring 231 within the locking space, and a plurality of locking claw heads 224 are inserted circumferentially on the edge of the claw seat 223. The locking claw head 224 is elastically connected to the edge of the seat 223 by a spring. Guide surfaces are provided on the top and bottom sides of the claw tip of the locking claw head 224. When the transmission joint 33 moves down to engage under the drive of the rotary drive mechanism 6, the locking claw head 224 is stretched outward from the edge of the claw seat 223 by the guide surface on the top side of the claw tip. The claw tip of the locking claw head 224 is inserted into the locking groove 3312 of the rotary buckle groove 331. When the transmission joint 33 moves up to move away under the drive of the rotary drive mechanism 6, the locking claw head 224 is stretched outward from the edge of the claw seat 223 by the guide surface on the bottom side of the claw tip of the locking claw head 224. The claw tip of the locking claw head 224 gradually leaves the locking groove 3312 of the rotary buckle groove 331, so that the rotary drive mechanism 6 can complete the rotation action of the clamp 3.

[0051] like Figures 8 to 10 and Figure 15 As shown, the driver 2 includes a mounting socket 22 for docking the drive joint 33, and the clamp 3 has multiple docking posts 34 on both sides.

[0052] The auxiliary device for performance testing of primary equipment in substations of the present invention further includes a rotary drive mechanism 6 for driving the clamp 3 to rotate the power output end of the docking driver 2. The rotary drive mechanism 6 includes: a mounting base 61; a lifting assembly 62, which is mounted on the mounting base 61 and whose power output end is detachably connected to the docking post 34; and a rotary transmission assembly 63, which is mounted on the power output end of the lifting assembly 62 and connected to the lifting assembly 62. After the lifting assembly 62 drives the clamp 3 to move upward away from the mounting socket 22, the clamp 3, under the elastic force of the rotary transmission assembly 63, causes the transmission joint 33 to reach the initial position. When the initial position does not meet the usage requirements, the lifting assembly 62 continues to drive the rotary transmission assembly 63, causing the clamp 3 to move upward and flip simultaneously to replace the transmission joint 33, thereby positioning and clamping the primary equipment terminal. After the positioning and clamping is completed, the lifting assembly 62 leaves the docking post 34 and performs self-locking of the circumferential docking position.

[0053] When the clamping direction of the clamping plate 32 needs to be changed at high altitude, it can be done through the rotary drive mechanism 6. After clamping is completed, the clamp 3 is released so that performance tests can be conducted by clamping the terminal block of the primary equipment. Specifically, the lifting assembly 62 on the mounting base 61 can drive the rotary transmission assembly 63 and the clamp 3 to move upward together. When the transmission joint 33 just leaves the mounting socket 22, each transmission joint 33 adaptively adjusts to its initial position. When it is discovered that the wiring direction of the primary equipment terminal in the captured image does not correspond to the clamping direction of the clamping plate 32 corresponding to the initial position, the lifting component 62 continues to move upward with the rotary transmission component 63 and the clamp 3. At the same time, the rotary transmission component 63 is linked to make the clamp 3 flip, so that another transmission connector 33 is connected to the mounting socket 22 of the driver 2 to realize the automatic replacement of the transmission connector 33. This adjusts the clamping direction of the clamping plate 32 to correspond to the wiring direction of the primary equipment terminal, ensuring the high efficiency of the clamping direction adjustment of the clamping plate 32. This avoids the time wasted by manually removing the clamp 3 and replacing it again when the clamping direction is found to be mismatched. Moreover, when the lifting driver 2 and the clamp 3 reach the side of the primary equipment terminal, they need to avoid a large number of cables and other obstacles in the way. Automatically replacing the transmission connector 33 in the air can also effectively reduce the risk of contact damage to nearby cables, equipment, etc. In addition, after the transmission connector 33 is replaced and the primary equipment terminal is clamped, the operator holds the operating lever 1 by hand and then uses the lifting assembly 62 to drive the transmission connector 33 upward. At the same time, the operator follows the downward movement of the operating lever 1, so that the transmission connector 33 leaves the mounting socket 22 of the driver 2. Just before leaving, the lifting assembly 62 is controlled to leave the docking post 34 and complete the self-locking of the circumferential docking position. Then, the operating lever 1 is moved downward again, so that the driver 2 and the rotary drive mechanism 6 are separated from the clamp 3. The performance test is then carried out by clamping the primary equipment terminal separately with the clamp 3, thereby ensuring the safety of the high-voltage test process.

[0054] like Figure 10 and Figure 11As shown, the lifting assembly 62 includes: a rotating shaft 621 located on both sides of the clamp 3; a lifting seat 622, one end of a set of rotating shafts 621 being rotatably mounted on the corresponding lifting seat 622, and the lower end of the lifting seat 622 being slidably inserted into the mounting base 61; and a lifting drive 623 mounted on the mounting base 61, one end of another set of rotating shafts 621 being rotatably passed through the corresponding lifting seat 622 and connected to the rotary transmission assembly 63, and the power output end of the lifting drive 623 being connected to the bottom of the corresponding lifting seat 622; a chuck 624 slidably inserted into the corresponding rotating shaft 621, and the chuck 624 having a docking hole 6241 corresponding to the docking post 34; and a locking disc 625 for locking. A disc 625 is located between a chuck 624 and a lifting seat 622. A locking disc 625 is installed on one side of the lifting seat 622. The locking disc 625 has a locking pin 6251 corresponding to the docking hole 6241. A traction rod 626 is provided, with one end of each traction rod 626 connected to the corresponding chuck 624. A locking drive 627 is rotatably mounted on the lifting seat 622. The other end of each traction rod 626 is connected to the power output end of the locking drive 627 to drive the chuck 624 connected to the traction rod 626 to move simultaneously toward the corresponding docking pin 34 to complete the docking and to position and clamp the primary equipment terminal. After the positioning and clamping are completed, the chuck 624 moves simultaneously toward the corresponding locking pin 6251 to self-lock the circumferential docking position of the chuck 624.

[0055] The lifting drive 623 can be a push rod motor, or other linear drive mechanisms. During the process of driving the rotary transmission assembly 63 and the clamp 3 to rise and switch the transmission connector 3, the lifting assembly 622 can lift the lifting seat 622 via the lifting drive 623, thereby linking the rotary transmission assembly 63 on one side of the lifting seat 622. This, in turn, causes the clamp 3 to rotate along with the rotating shaft 621, thus switching the transmission connector 33 to the mounting socket 22.

[0056] Furthermore, after the corresponding transmission joint 33 completes the switching and docking with the mounting socket 22, the driver 2 drives the clamp 33 to position and clamp the primary equipment terminal block. After positioning and clamping, to ensure the safety of the performance test, the transmission joint 33 can be raised by controlling the lifting drive 623, causing it to leave the mounting socket 22. Just before it is completely away from the mounting socket 22, the locking drive 627, which is rotatably connected to the lifting seat 622, drives the chuck 624 connected to the traction rod 626 to leave the clamp 3. This causes the docking post 34 on the clamp 3 to separate from the docking hole 6241 on the chuck 624. The chuck 624, continuing to move, then locks itself into the locking post 6251 of the locking disc 625 connected to the lifting seat 622 on the other side through its docking hole 6241, achieving circumferential locking of the chuck 624 for performance testing. Furthermore, after the test is completed, the chuck 624, with the mating hole 6241 positioned as determined, can be directly inserted back into the mating post 34 positions on both sides of the fixture 3. The locking drive 627 is then used to drive the chuck 624 again, allowing the mating hole 6241 to engage with the mating post 34 once more. The fixture 3 can then be released by loosening the primary equipment terminal and removing it. The locking drive 627 can be a servo motor, or other rotary power component. To ensure accurate mating between the chuck 624 and the mating post 34 and locking post 6251, the ends of both the mating post 34 and locking post 6251 can be chamfered, facilitating the smooth insertion of the chuck 624's mating hole 6241 into the corresponding mating post 34 or locking post 6251.

[0057] like Figures 11 to 13As shown, the rotary transmission assembly 63 may further include: a transmission gear 631, which is slidably connected to the rotary shaft 621 along the axial direction of the rotary shaft 621, and a limiting groove 6311 is provided on one side of the transmission gear 631, and a first locking tooth is provided on the side wall of the transmission gear 631; a limiting disk 632, which is disposed on one side of the transmission gear 631, is mounted on the lifting seat 622, and a second locking tooth corresponding to the first locking tooth is provided on the end side of the limiting disk 632; The second elastic element 633 is located inside the limiting disc 632. One end of the second elastic element 633 is connected to the transmission gear 631, and the other end is connected to one side of the lifting seat 622. A limiting rod 634 has one end slidably inserted into one side of the lifting seat 622, and the other end slidably disposed within the limiting groove 6311. A drive guide mechanism 635 is mounted on the mounting base 61 and drives the guide rail... The guide rail mechanism 635 is located on one side of the transmission gear 631, and the extended end 6211 of the rotating shaft 621 is inserted into the drive guide rail mechanism 635; and the toothed plate 636, the top end of the toothed plate 636 is elastically slidably mounted on the drive guide rail mechanism 635; wherein, after the rotating shaft 621 moves upward away from the mounting socket 22, the transmission gear 631 rotates under the elastic force of the second elastic element 633, so that the limiting rod 634 reaches one end of the limiting groove 6311, and the transmission joint 33 reaches the initial position. When the initial position does not meet the usage requirements, the rotating shaft 621 continues to move upward, and the extended end 6211 of the rotating shaft 621, under the guidance of the drive guide rail mechanism 635, makes the transmission gear 631 mesh with the toothed plate 636, so that the clamp 3 flips to switch the transmission joint 33. When the switching is completed, the drive guide rail mechanism 635 makes the first locking tooth contact and lock on the second locking tooth, and drives the switched transmission joint 33 to be inserted into the mounting socket 22 for docking and locking through the lifting drive 623. The second elastic element 633 can be a torsion spring, or it can be an elastic element formed by a combination of other torsion springs and springs. Of course, it can also be other elastic elements that can simultaneously achieve torsional elasticity and linear elasticity.

[0058] During the rotation of the rotary transmission assembly 63 together with the transmission clamp 3, when the lifting drive 623 drives the transmission joint 33 to leave the mounting socket 22, the second elastic element 633 will rotate the transmission gear 631 in its free state. At the same time, through the movement of the limiting rod 634 inserted on one side of the lifting seat 622 within the limiting groove 6311, when the limiting rod 634 reaches one end of the limiting groove 6311, the transmission gear 631 is restricted from continuing to rotate. At this time, the transmission gear 631 reaches its original position, and the transmission joint 33 is reset to its initial position. If the initial position does not meet the requirements, the lifting drive 623 will continue to drive the transmission gear 631 to move upward. At the same time, when the extended end 6211 of the rotating shaft 621 moves upward, it drives the drive guide mechanism 635, so that the toothed plate 636 reaches one side of the transmission gear 631 and meshes with the transmission gear 631, causing the transmission gear 631 to rotate with the clamp 3 to switch the transmission joint 33. When the transmission joint 33 is switched, as the transmission gear 631 continues to move upward, it will be pushed towards the limiting plate 632 by the drive guide mechanism 635. This causes the first locking tooth on the side of the transmission gear 631 to contact and lock with the second locking tooth on the side of the limiting plate 632. At the same time, under the continuous locking of the drive guide mechanism 635, the lifting drive 623 drives the switched transmission joint 33 to move down to the mounting socket 22 for locking, thereby realizing the automatic replacement of the transmission joint 33 and ensuring that the clamping direction of the clamping plate 32 automatically adapts to the wiring direction of the primary equipment terminal during high-altitude operations.

[0059] For example, when the primary equipment terminals are arranged horizontally, the two clamping plates 32 can be driven to be arranged vertically, that is, the clamping direction is vertical. When the primary equipment terminals are arranged vertically, the two clamping plates 32 can be driven to be arranged horizontally, that is, the clamping direction is horizontal.

[0060] like Figure 11 and Figure 13As shown, the drive guide rail mechanism 635 includes: a guide base 6351, which is mounted on the mounting base 61; a track plate 6352, which is slidably disposed on the guide base 6351, and the track plate 6352 is provided with an annular guide rail 6353. The top end of the annular guide rail 6353 is provided with an inner elastically inserted first limiting block 6354, and the lower end of the annular guide rail 6353 is provided with an inner elastically inserted second limiting block 6355. The protruding end 6211 of the rotating shaft 621 is inserted into the annular guide rail 6353; and a pad 6356, which is installed on one side of the track plate 6352, and the pad 6356 is connected to the transmission gear. Corresponding to the side surface of 631, the pad 6356 is located on the side away from the toothed plate 636. The top side of the pad 6356 is provided with a slope surface corresponding to the transmission gear 631. The transmission gear 631 rotates on the toothed plate 636 until the transmission joint 33 is rotated and changed. The transmission gear 631 pushes the toothed plate 636 to continue to move upward, so that the transmission gear 631 contacts the pad 6356. The transmission gear 631 moves towards the lifting seat 622. After the first locking tooth and the second locking tooth are locked, the protruding end 6211 of the rotating shaft 621 moves down along the other side of the annular guide rail 6353 to the lowest point, so that the rotated transmission joint 33 is connected to the mounting socket 22.

[0061] During the process of driving the drive guide mechanism 635, the extended end 6211 of the rotating shaft 621 moves within the annular guide rail 6353 of the track plate 6352. Before the extended end 6211 of the rotating shaft 621 moves upward within the annular guide rail 6353, it is located on one side of the second limiting block 6355 and is limited by the second limiting block 6355, and can only move upward from the first side of the annular guide rail 6353. When the transmission joint 33 leaves the mounting socket 22, the transmission gear 631 is in a free state, and under the elastic force of the second elastic element 633, each transmission joint 33 returns to its initial position. When the initial position of the transmission joint 33 does not meet the clamping direction requirements of the primary equipment terminal, the transmission gear 631 continues to move upward, causing the track plate 6352 to slide on the guide base 6351, thereby causing the toothed plate 636 to mesh with the transmission gear 631 for transmission. The transmission gear 631, which continues to move upward, rotates due to meshing with the toothed plate 636, thereby driving the transmission joint 33 to rotate and change position. After the transmission joint 33 has changed position, the transmission gear 631, which continues to move upward, contacts the pad 6356, and is pushed by the pad 6356 towards the limiting plate 632, so that the first locking tooth and the second locking tooth lock each other until the protruding end 6211 of the rotating shaft 621 passes the first limiting block 6354 and reaches the second side of the annular guide rail 6353. After the protruding end 6211 of the rotating shaft 621 passes the first limiting block 6354, it is blocked by the first limiting block 6354 and cannot return to the first side of the annular guide rail 6353. When the extended end 6211 of the rotating shaft 621 moves downward after reaching the second side of the annular guide rail 6353, the driven gear 631 continuously contacts the pad 6356, thereby locking the position of the replaced transmission connector 33 until the replaced transmission connector 33 is inserted into the mounting socket 22 to complete the docking.

[0062] The first limiting block 6354 and the second limiting block 6355 are both inserted into the annular guide rail 6353 and are connected to the inner wall of the track plate 6352 by springs. The first limiting block 6354, near the first side of the annular guide rail 6353, has a rounded side. The plane of the surface of the first limiting block 6354 near the second side of the annular guide rail 6353 coincides with the plane of the entry position surface of the second side of the annular guide rail 6353. The insertion direction of the first limiting block 6354 is parallel to the direction in which the protruding end 6211 of the rotating shaft 621 enters the second side of the annular guide rail 6353. The second limiting block 6355, near the second side of the annular guide rail 6353, has a rounded side. The plane of the surface of the second limiting block 6355 near the first side of the annular guide rail 6353 coincides with the plane of the entry position surface of the first side of the annular guide rail 6353. The insertion direction of the second limiting block 6355 is parallel to the direction in which the protruding end 6211 of the rotating shaft 621 enters the first side of the annular guide rail 6353.

[0063] By using the rotary transmission component 63 to link with the lifting component 62 to switch the transmission joint 33, the clamping direction of the clamping plate 32 can be accurately switched. At the same time, the orderly removal and switching of the transmission joint 33 from the installation socket 22 can be achieved through a single power source, ensuring the safe switching of the transmission joint 33.

[0064] like Figure 11 As shown, the toothed plate 636 includes: a toothed plate body 6361, which is slidably connected to one side of the drive guide mechanism 635; an upper baffle 6362, one end of which is connected to the top end of the toothed plate body 6361; a guide post 6363, the lower end of which is connected to the upper baffle 6362, and the upper end of which is slidably inserted into the drive guide mechanism 635; and a third elastic element 6364, which is connected between the upper baffle 6362 and the drive guide mechanism 635. The third elastic element 6364 can be a spring, or other elastic elements.

[0065] After the transmission gear 631 rotates in engagement with the toothed plate body 6361, it contacts the upper baffle 6362, thus pushing the upper baffle 6362 and the toothed plate body 6361 upwards together. The third elastic element 6364 is in an elastically compressed state. Through the continuous engagement of the transmission gear 631 and the toothed plate body 6361, the rotation angle of the transmission gear 631 remains unchanged. The continuing upward movement of the transmission gear 631 will contact the pad strip 6356, thereby pushing the transmission gear 631 towards the limiting disc 632, causing the first locking tooth to contact and lock onto the second locking tooth. Subsequently, while maintaining the switching state of the transmission joint 33, it moves downwards until the transmission joint 33 aligns with the mounting socket 22. In this way, the position locking of the transmission gear 631 during downward movement can be effectively guaranteed, so as to complete the precise switching of the transmission joint 33.

[0066] The substation primary equipment performance testing auxiliary device of the present invention further includes: a processor, used to acquire captured images; identify the wiring direction of the primary equipment terminals in the captured images; determine whether the wiring direction corresponds to the clamping direction of the clamping plate 32; if not, send a clamping direction switching command to the rotary drive mechanism 6 to switch the transmission joint 33. The processor can be installed inside the lifting assembly 62 or can be independently installed at the lower end of the operating lever 1 to communicate with the lifting assembly 62, such as through Bluetooth connection, Wi-Fi signal connection, etc., or it can be located in other positions.

[0067] The process of determining whether the wiring direction corresponds to the clamping direction of the clamping plate 32 may further include: Based on the wiring direction, a desired clamping direction for the clamping plate 32 is generated. The angle between the desired clamping direction and the clamping direction of the clamping plate 32 is calculated to obtain the angle difference. When the angle difference is less than an angle difference threshold, a clamping direction switching command is generated. The angle difference threshold can be less than or equal to 45°, or it can be other angle difference values.

[0068] The camera unit 5 may include a camera and a fill light to provide illumination for image acquisition when there is insufficient lighting.

[0069] Additionally, a monitoring and display device 7 is installed at the lower end of the operating lever 1. The monitoring and display device 7 includes a device bracket 71 and a mobile monitoring device 72 detachably mounted on the device bracket 71. The mobile monitoring device 72 communicates with the camera unit 5, for example, via Bluetooth or Wi-Fi. Alternatively, the software control program can be configured in the mobile monitoring device 72 to acquire captured images; identify the wiring direction of the primary equipment terminals in the captured images; determine whether the wiring direction corresponds to the clamping direction of the clamping plate 32; and if not, send a clamping direction switching command to the rotary drive mechanism 6 to switch the transmission joint 33. This allows the mobile monitoring device 72 to directly send the clamping direction switching command to the rotary drive mechanism 6 when it determines that a change in clamping direction is needed.

[0070] In summary, the present invention discloses an auxiliary device for performance testing of primary equipment in substations. Test personnel can connect the high-voltage withstand voltage test lead to the grounding wire mounting post 4, hold the operating lever 1, and lift and move the driver 2 and the clamp 3 connected to the power output terminal of the driver 2 to the substation primary equipment side on a high support or platform. The clamp 3 positions and clamps the terminals of the substation primary equipment, and an electrical connection is established between the clamp 3 and the grounding wire mounting post 4, achieving circuit continuity and completing various performance tests. When the clamp 3 reaches the terminals of the primary equipment, the camera unit 5 can capture images of the terminal layout. Based on the wiring direction of the terminals in the captured image, the corresponding transmission connector 33 can be selected to connect with the power output terminal of the driver 2. After connection, the clamp 32 corresponding to the wiring direction positions and clamps the terminals. After positioning and clamping, the clamp 3 is released. This improves the convenience and safety of performance testing of transformer primary equipment, replaces traditional climbing operations, and eliminates the safety risks of falls from heights and electric shocks. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0071] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
