Description

Technical Field

[0001] This invention relates to the field of high-voltage disconnecting switch technology, and in particular to a copper busbar torsion device for a disconnecting switch. Background Technology

[0002] A high-voltage disconnector is a switchgear that, when in the open position, has an insulation distance between contacts that meets the specified requirements and a clear disconnection mark; when in the closed position, it can carry current under normal circuit conditions and current under abnormal conditions (such as short circuit) within a specified time. To meet the operating requirements of high-voltage disconnectors, the copper busbar components of high-voltage disconnectors need to be twisted, with a twist angle requirement between 80° and 145°.

[0003] Currently, the copper busbar components of high-voltage disconnect switches are formed by manual twisting. Specifically, one end of the copper busbar is fixed, and then manually twisted to a specified angle at a certain distance. Although this method can meet production needs, it also has many drawbacks: 1. It is difficult to keep the twisting angle consistent each time, and rework is often required to correct the twisting angle; 2. The rotation center is not accurately controlled during manual twisting, which easily leads to twisting eccentricity and rework; 3. Workers are prone to fatigue due to long hours of physical labor, which can easily cause safety accidents and poses a safety hazard.

[0004] In summary, the current method of forming high-voltage disconnect switch copper busbars by twisting presents both low production efficiency and significant safety hazards.

[0005] In view of this, it is necessary to propose a copper busbar torsion device for disconnecting switches to solve or at least alleviate the above-mentioned defects. Summary of the Invention

[0045] Please see Figures 1 to 10 An embodiment of the present invention provides a copper busbar torsion device for a disconnecting switch, comprising an operating platform 10 and a copper busbar clamping mechanism 20 and a copper busbar torsion assembly 30 disposed on the top of the operating platform 10, wherein the copper busbar clamping mechanism 20 and the copper busbar torsion assembly 30 are correspondingly arranged; wherein,

[0046] The copper busbar clamping mechanism 20 includes a bracket 210, an upper cylinder 220, a lower cylinder 230, an upper sliding block 240 connected to the drive end of the upper cylinder 220, and a lower sliding block 250 connected to the drive end of the lower cylinder 230; wherein, the drive end of the cylinder is the push rod of the drive cylinder, which is a technical content well known to those skilled in the art.

[0047] The bracket 210 has a first sliding groove 211 for the upper sliding block 240 to slide vertically and a second sliding groove 212 for the lower sliding block 250 to slide vertically. The lower cylinder 230 is mounted on the operating platform 10 and driven vertically upward. The upper cylinder 220 is mounted on the bracket 210 and driven vertically downward. The upper cylinder 220 is located directly above the lower cylinder 230 and is used to clamp the copper busbar 40 between the upper sliding block 240 and the lower sliding block 250.

[0048] The copper busbar torsion assembly 30 includes a drive mechanism (not shown) and a torsion mechanism 330. The torsion mechanism 330 has a through hole 3351 through which the copper busbar 40 passes and whose shape matches the copper busbar 40. The copper busbar 40 extends outward from the copper busbar clamping mechanism 20 and extends out of the through hole 3351. The drive mechanism drives the torsion mechanism 330 to rotate so that the copper busbar 40 undergoes torsion deformation.

[0049] In a preferred embodiment, the torsion mechanism 330 includes a copper busbar torsion assembly 331, a second support plate 332, a first gear 333, a transmission sleeve 334, a torsion chuck 335, and two first bearings 336 that are sleeved on the outer periphery of the transmission sleeve 334. The copper busbar torsion assembly 331 and the second support plate 332 are arranged parallel to each other along the extension direction of the copper busbar 40 and are connected to the operating platform 10. The copper busbar torsion assembly 331 has a first mounting through hole (not shown) for the installation of the first bearing 336, and the second support plate 332 has a second mounting through hole (not shown) for the installation of the other first bearing 336. The second mounting through hole is arranged corresponding to the first mounting through hole and extends along the extension direction of the copper busbar 40.

[0050] The two ends of the transmission sleeve 334 are respectively connected to the inner wall of the corresponding first bearing 336. The outer periphery of the transmission sleeve 334 is provided with a limiting shoulder 3341 that matches the end face of the first bearing 336. The transmission sleeve 334 has a mounting groove 3342 for mounting the torsion chuck 335. The outer periphery of the transmission sleeve 334 is provided with a first keyway 3343 extending along its own extension direction.

[0051] The torsion chuck 335 is installed in the mounting groove 3342. The torsion chuck 335 has a through hole 3351, which communicates with the inner cavity of the transmission sleeve 334. The first gear 333 is located between the copper busbar torsion assembly 331 and the second support plate 332. The first gear 333 is sleeved on the outer periphery of the transmission sleeve 334. The inner wall of the first gear 333 has a second keyway (not shown in the figure) that matches the first keyway 3343. The first gear 333 and the transmission sleeve 334 are connected by a key.

[0052] In this technical solution, by using an upper cylinder 220 and a lower cylinder 230 to drive the corresponding sliding blocks to move relative to each other, one end of the copper busbar 40 is clamped. The other end is clamped by the torsion chuck 335 of the torsion mechanism 330. By controlling the rotation of the reducer, the second gear 322 and the first gear 333 mesh and transmit power. The first gear 333 drives the transmission sleeve 334 to rotate, thereby driving the torsion chuck 335 installed in the positioning groove 251 to rotate. Since the copper busbar 40 passes through the through hole 3351 of the torsion chuck 335, the torsion deformation of the copper busbar 40 can be achieved, converting manual forming into electric forming and reducing the human workload. Secondly, the pneumatic clamping of the cylinder is quick and stable, and the gear transmission ensures stable and balanced output force. The consistency of torsion forming greatly improves the production quality of the product. It effectively reduces fatigue caused by continuous manual work and effectively reduces the harm to workers during the torsion forming process.

[0053] In a preferred embodiment, the drive mechanism includes a drive motor 310 and a reduction mechanism 320, wherein the drive end of the drive motor 310 is connected to the input end of the reduction mechanism 320, and the output end of the reduction mechanism 320 is connected to the first gear 333. Further, the reduction mechanism 320 includes a reduction gearbox 321, a second gear 322, a third support plate 210, and a second bearing 324; wherein the third support plate 210 has a third mounting through hole for mounting the second bearing 324, the second bearing 324 is mounted in the third mounting through hole, the output end of the reduction gearbox 321 is connected to the second bearing 324, the second gear 322 is located between the reduction gearbox 321 and the third support plate 210, the second gear 322 is mounted on the outer periphery of the output end of the reduction gearbox 321, and meshes with the first gear 333. For example, the reduction gearbox 321 can be a gear reducer 321. The drive motor 310 and the reduction gearbox 321 can be driven by gears. The output end of the reduction gearbox 321 is specifically a shaft. The second gear 322 and the shaft can be connected by a key to realize the transmission.

[0054] In this embodiment, since the high-voltage disconnect switch copper busbar 40 component needs to be twisted, the required twist angle is between 80° and 145°. By setting the deceleration mechanism 320, the speed of the relatively high-speed drive electric motor can be reduced, thereby meeting the required twist angle.

[0055] Furthermore, the operating platform 10 has a first through hole (not shown in the figure) extending vertically. The lower cylinder 230 is installed at the bottom of the operating platform 10, and the driving end of the lower cylinder 230 is connected to the upper sliding block 240 located above the operating platform 10 through the first through hole. The driving end of the cylinder is the cylinder push rod.

[0056] As a specific example, the bracket 210 is in the shape of a cuboid, and the bracket 210 has a first sliding groove 211 extending upward from the bottom, and a second sliding groove 212 extending upward from the bottom of the first sliding groove 211.

[0057] Furthermore, the width of the first slide groove 211 is greater than the width of the second slide groove 212. When the width of the first slide groove 211 is greater than the width of the second slide groove 212, that is, when the transition position of the first slide groove 211 and the second slide groove 212 has a step, the maximum value of the driving stroke of the lower cylinder 230 can be set to the bottom position of the first slide groove 211. Furthermore, the height corresponding to this position is set to match the height of the torsion chuck 335 so that the copper busbar 40 can be in a horizontal state when clamped, improving the consistency of each torsion.

[0058] Further, please refer to the appendix. Figure 3 The top of the bracket 210 has a second through hole (not shown) that connects to the second slide groove 212. The upper cylinder 220 is mounted on the top of the bracket 210, and the driving end of the upper cylinder 220 is connected to the upper sliding block 240 disposed in the second slide groove 212 through the second through hole. In another embodiment, the upper cylinder 220 can also be disposed in the space corresponding to the second slide groove 212. In this case, the height of the bracket 210 can be increased to ensure sufficient space for the movement stroke of the driving end of the upper cylinder 220.

[0059] In a preferred embodiment, the top of the lower sliding block 250 is provided with a positioning groove 251 that matches the copper busbar 40, such as... Figure 3 As shown, a positioning groove 251 matching the copper busbar 40 is provided on the top of the sliding block 250. The two sides of the positioning groove 251 can limit the copper busbar 40 in the width direction, so as to better position the copper busbar 40.

[0060] Further, please refer to Figure 2 The operating platform 10 includes a support leg 110 and a top plate 120 connected to the top of the support leg 110, and the lower cylinder 230 is installed at the bottom of the top plate 120.

[0061] In another preferred embodiment, a control box 50 is also included, and the drive motor 310, upper cylinder 220, and lower cylinder 230 are all connected to the control box 50. A schematic diagram of the control panel can be found in [reference needed]. Figure 10 The specific operation process / logic is as follows:

[0062] S1, connect the power and gas supply;

[0063] S2, release the emergency stop, press the power button, and adjust the knobs of the upper cylinder 220 and the lower cylinder 230 to the release position (the release position corresponds to the retracted state of the cylinder push rod);

[0064] S3, Reset: Rotate the torsion chuck 335 back to the horizontal starting angle, adjust the knob of the lower cylinder 230 to the tight position (push the lower slider upward), put the copper busbar 40 into the positioning slot 251 and insert it into the torsion chuck 335;

[0065] S4, adjust the knob of the lower cylinder 230 to the tight position, push the lower sliding plate upward, put the copper busbar 40 into the positioning groove 251 and insert it into the through hole 3351 of the torsion chuck 335;

[0066] S5, adjust the knob of the upper cylinder 220 to the tight position, push the upper sliding plate down, so that the upper sliding block 240 and the lower sliding block 250 firmly clamp the copper busbar 40 and position it.

[0067] S6, Start: Press the start button, the reduction mechanism 320 works to drive the second gear 322 to rotate, which in turn drives the first gear 333 to rotate, and causes the torsion chuck 335 to move in conjunction;

[0068] S7, twist to a specified angle (e.g., 120°), control the deceleration mechanism 320 to stop outputting torque (e.g., it can be detected by a limit switch, and the twist angle can be adjusted by adjusting the detection position of the limit switch to achieve multi-angle adjustment), and the torque stops;

[0069] S8, adjust the knobs of the upper cylinder 220 and the lower cylinder 230 to the loose position in sequence, remove the copper busbar 40, and complete one rotation of the copper busbar 40.
