Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically a busbar clamping device with dual pressure. Background Technology

[0002] In power systems, busbars connect the various current-carrying branch circuits in the distribution equipment, playing a role in collecting, distributing, and transmitting electrical energy. Busbars are typically made of copper or aluminum, which offer high current density, low resistance, and minimal skin effect, eliminating the need for derating. However, existing busbars are densely packed within a casing, which lacks robust pressure-locking measures. Therefore, when current flows through the busbars, they generate electrodynamic forces, causing mechanical vibrations that result in noise and wear. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a busbar clamping device with dual pressure.

[0004] The technical solution of this utility model is as follows: A dual-pressure busbar clamping device includes a transport mechanism, a housing, an upper pressure mechanism, and a side pressure mechanism. The transport mechanism has multiple rotatably connected rollers along its length, and the housing wraps around the busbar and moves along the rollers.

[0005] Furthermore, the outer casing includes a front panel and side panels. The front panel is provided on both the top and bottom of the busbar, and the side panels are provided on both sides of the front panel. The front panel and side panels are provided with multiple evenly spaced positioning holes.

[0006] Furthermore, wedge-shaped pads are provided between the top and bottom surfaces of the panel and the busbar, and wedge-shaped pads are provided between the side panels and the sides of the busbar.

[0008] Furthermore, the transport mechanism is equipped with multiple upper pressure mechanisms and side pressure mechanisms along its length. The upper pressure mechanisms are fixedly connected to the transport mechanism via upper supports, and the side pressure mechanisms are fixedly connected to the transport mechanism via lower supports.

[0009] Furthermore, the side-pressure mechanism includes a side-pressure cylinder and a slider. The side-pressure cylinder is fixedly connected to the lower support, and the lower support is provided with a guide rail that mates with the slider. The telescopic end of the side-pressure cylinder is fixedly connected to the slider. A vertical rod is provided on the slider, and a PU plate is provided at the end of the vertical rod away from the slider.

[0010] Furthermore, a side-top mechanism is provided on the side of the upper support away from the PU board. The side-top mechanism includes a support rod and a top plate. One end of the support rod is fixedly connected to the support, and the other end is provided with the top plate.

[0011] Furthermore, the pressing mechanism includes a pressing cylinder, a fixed plate, and a pressing block. The pressing cylinder is fixedly connected to the upper support, and the telescopic end of the pressing cylinder passes through the upper support and is fixedly connected to the fixed plate. The fixed plate is provided with a slidably connected pressing block.

[0012] Furthermore, the fixed plate is provided with a slide rail that matches the pressure block, and pressure blocks are provided on both sides of the fixed plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0022] like Figures 1-4 As shown, a dual-pressure busbar clamping device includes a transport mechanism 1, a housing 2, an upper pressure mechanism 3, and a side pressure mechanism 4. The transport mechanism 1 has multiple rotatably connected rollers 11 along its length. The housing 2 wraps around the busbar 5 and moves along the rollers 11. The upper pressure mechanism 3 is located at the top of the housing 2, and the side pressure mechanism 4 is located at the bottom. The upper pressure mechanism 3 applies pressure to the top and bottom of the housing 2, causing the housing 2 to exert an external force on the busbar 5 in the vertical direction, preventing the busbar 5 from vibrating in the vertical direction. The side pressure mechanism 4 applies external force to both sides of the housing 2, preventing the busbar 5 from vibrating in the horizontal direction.

[0023] The outer casing 2 includes a front panel 21 and side panels 22. The busbar 5 is provided with the front panel 21 on both its top and bottom surfaces, and with side panels 22 on both sides of the front panel 21. Both the front panel 21 and side panels 22 have multiple evenly spaced positioning holes 24. Under the action of the upper pressing mechanism 3 and the side pressing mechanism 4, the positioning holes 24 of the front panel 21 and side panels 22 engage with each other, and are then fixedly connected by fasteners. Wedge-shaped pads 25 are provided between the front panel 21 and the top and bottom surfaces of the busbar 5, and wedge-shaped pads 25 are also provided between the side panels 22 and the sides of the busbar 5. The wedge-shaped pads 25 deform under the action of the front panel 21 and side panels 22, allowing the busbar 5 to maintain a stable relative static state with the outer casing 2 under the rebound stress of the wedge-shaped pads 25. An H-shaped partition 26 is provided inside the outer casing 2, separating the busbar 5 into the upper and lower layers of the outer casing 2. The sides of the H-shaped partition 26 contact the wedge-shaped pads 25. The busbar 5 is generally quite long. The H-shaped partition 26 keeps the busbar 5 in a stable, flat position along its length, preventing external forces from squeezing the outer shell 2 and causing the busbar 5 to shift position. The side of the panel 21 and the side panel 22 away from the outer shell 2 are provided with multiple protruding ribs 23. The protruding ribs 23 can improve the deformation resistance of the panel 21 and the side panel 22, preventing excessive irreversible deformation of the panel 21 or the side panel 22 during the pressure process.

[0024] The transport mechanism 1 is provided with multiple upper pressing mechanisms 3 and side pressing mechanisms 4 along its length. The upper pressing mechanisms 3 are fixedly connected to the transport mechanism 1 via upper brackets 12, and the side pressing mechanisms 4 are fixedly connected to the transport mechanism 1 via lower brackets 13. By applying external force evenly to different areas of the outer shell 2 through multiple upper pressing mechanisms 3 and side pressing mechanisms 4, uneven force on the front and back of the outer shell 2 is prevented.

[0025] The side-pressure mechanism 4 includes a side-pressure cylinder 41 and a slider 42. The side-pressure cylinder 41 is fixedly connected to the lower support 13. The lower support 13 is provided with a guide rail 131 that cooperates with the slider 42. The telescopic end of the side-pressure cylinder 41 is fixedly connected to the slider 42. The slider 42 is provided with a vertical rod 421. A PU plate 422 is provided at the end of the vertical rod 421 away from the slider 42. The side-pressure cylinder 41 drives the slider 42 to move towards the outer shell 2. The slider 42, through the vertical rod 421, drives the PU plate 422 to apply external force to the side plate 22. The upper support 12 is provided with a side-top mechanism 43 on the side away from the PU plate 422. The side-top mechanism 43 includes a support rod 431 and a top plate 432. One end of the support rod 431 is fixedly connected to the support, and the other end is provided with the top plate 432. The top-pressure mechanism cooperates with the side-pressure mechanism 4 to make the busbar 5 subject to pressure from the outer shell 2 in the horizontal direction.

[0026] The pressing mechanism 3 includes a pressing cylinder 31, a fixed plate 32, and pressing blocks 33. The pressing cylinder 31 is fixedly connected to the upper support 12. The telescopic end of the pressing cylinder 31 passes through the upper support 12 and is fixedly connected to the fixed plate 32. The fixed plate 32 is provided with slidably connected pressing blocks 33. The fixed plate 32 is provided with a slide rail 321 that matches the pressing blocks 33. Pressing blocks 33 are provided on both sides of the fixed plate 32. The pressing cylinder 31 drives the pressing blocks 33 to apply pressure to the top of the outer shell 2, so that the panel 21 is tightly pressed against the outer shell 2. Multiple pressing blocks 33 facilitate the uniform application of external force to the panel 21. The pressing blocks 33 can move along the slide rail 321, which facilitates the adjustment of the position of the pressing blocks 33 according to the position of the outer shell 2 on the transport mechanism 1.

[0027] The working principle of this utility model is as follows: the busbar 5 is placed inside the outer casing 2. The side pressing mechanism 4 applies external force to the side plates 22 on both sides of the busbar 5, and the upper pressing mechanism 3 applies external force to the upper and lower panels 21 of the busbar 5. When the side plates 22 coincide with the positioning holes 24 on the panel 21, the side plates 22 and the panel 21 are fixedly connected by fasteners. At this time, the busbar 5 is under the pressure of the outer casing 2, preventing vibration during operation.
