DETAILED DESCRIPTION

[0047] Embodiment of the bus terminal-isolating switch supporting structure of the utility model:

[0048] The utility model connects the busbar end support mechanism and the disconnector support structure together through the base support structure to form an integrated support, which solves the problem that the equipment support points are difficult to set due to the compact structure, layout requirements and other limiting factors of miniaturized equipment. The integrated support is easy to package and convenient to transport to the site, and it also provides convenience for on-site installation of the substation and saves installation time.

[0049] like Figures 1-2 As shown, a busbar terminal-disconnector support structure includes a busbar terminal support structure, a disconnector support structure and a bottom support structure 19, wherein the busbar terminal support structure and the disconnector support structure are both fixedly connected to the base support structure 19.

[0050] Specifically, Figures 6 to 9 As shown, the base support structure 19 includes two parallel cross beams 30, and two longitudinal beams are fixedly connected between the two cross beams, namely the first longitudinal beam 31 and the second longitudinal beam 32. Among them, the cross beam is consistent with the extension direction of the busbar, and the longitudinal beam is perpendicular to the cross beam. The base support structure 19 has three support positions, namely, a large-pitch double-foot support position 27, a small-pitch double-foot support position 28, and a single-foot support position 29. The two support points of the large-pitch double-foot support position 27 are completely set on the cross beam 30, and the support points of the small-pitch double-foot support position 28 are located at both ends of the first longitudinal beam 31. The part extending out of the first longitudinal beam 31 is fixedly connected to the cross beam 30, and the single-foot support position 29 is located in the middle of the second longitudinal beam 32.

[0051] In other embodiments, the two support points of the small-pitch double-foot support positions may be completely disposed on the longitudinal beam and may not extend outwardly to the transverse beam.

[0052] Specifically, the busbar end support structure is arranged on the large-spacing double-leg support position 27. Figure 2 As shown, the busbar end support structure includes a leg weldment 8 and a bracket weldment 9. The bracket weldment 9 has a support surface for supporting the busbar end so that the busbar end is fixed on the busbar end support structure. The leg weldment 8 is fixedly connected to the base support structure 19 by bolts. The bolt fixation makes the connection stable and easy to assemble. The leg weldment 8 is connected to the support weldment 9 by an adjustment screw 1. The height of the bracket weldment 9 can be adjusted by adjusting the screw 1 so that the busbar end can be supported at different heights to facilitate adapting to various working conditions at different sites.

[0053] Specifically, Figure 5 As shown, there are 4 adjusting screws 1, and the length is 350 mm, which has sufficient adjustment margin. Each adjusting screw 1 is provided with a first spring washer 2, a first washer 3 and a first hexagonal nut 4, so that the connection is more stable and has a certain impact resistance.

[0054] In other embodiments, the number of the adjusting screws 1 may be three or five, as long as the height of the bracket welding assembly 9 can be adjusted by adjusting the screws 1 and the support is stable.

[0055] In other embodiments, the leg welding assembly 8 can be set as a telescopic structure, for example: the leg welding assembly 8 includes a movable tube and a fixed tube sleeved outside the movable tube, a plurality of limiting holes are provided on the wall of the fixed tube, and an elastic limiting assembly matching the limiting holes is provided on the wall of the movable tube; the function of adjusting the height of the bracket welding assembly 9 is achieved by matching the movable tube with the fixed tube. In this case, the adjusting screw 1 may not be provided, and the leg welding assembly 8 may be fixedly connected or welded to the bracket welding assembly 9 by bolts and nuts.

[0056] In addition, a plurality of ribs are welded on the top of the leg welding assembly 8 and the support plate of the bracket welding assembly 9 to enhance the bearing capacity of the leg welding assembly 8 and the bracket welding assembly 9. A conductive block 33 is also provided at the bottom of the leg welding assembly 8.

The mechanism side support is arranged on a small-pitch double-leg support position 28. Specifically, since the mechanism side support needs to withstand a large output torque from the disconnector when closing / opening, two first pillar weldings 16 are provided, which are respectively fixed on both sides of the axial direction of the disconnector mechanism side by bolts, and the two first pillar weldings 16 are reinforced by a support angle steel 25 to increase the reliability of the support, so as to make the support structure more stable. The first pillar welding 16 is fixed to the support angle steel 25 by a third hexagonal bolt 15, and the third hexagonal bolt 15 is provided with a third washer 11, a third spring washer 12 and a third hexagonal head nut 13.

[0058] In other embodiments, only one first pillar welding device may be provided below the isolating switch at a position corresponding to the axis.

[0059] The non-mechanism side support is arranged on the single-leg support position 30. Specifically, the non-mechanism side support includes a support welding 18 and a second pillar welding 17. The support welding 18 is fixed to the non-mechanism side of the disconnector by a second hexagonal bolt 14, and a third washer 11 and a third spring washer 12 are arranged on the second hexagonal bolt 14. An adjusting gasket 20 is arranged between the support welding 18 and the disconnector, and the height error is compensated by adjusting gaskets of different numbers or thicknesses. Specifically, there are three adjusting gaskets, namely, a first adjusting gasket 20 with a thickness of 1mm, a second adjusting gasket 21 with a thickness of 2mm, and a third adjusting gasket 22 with a thickness of 5mm. In other embodiments, the number and thickness of the adjusting gaskets are more than this, and can be reasonably selected according to actual needs. The support welding 18 is fixedly connected to the second pillar welding 17 by a first bolt 10. The second pillar welding 23 is fixedly connected to the base support structure 19 by a first hexagonal bolt 10, and a third washer 11, a third spring washer 12 and a third hexagonal head nut 13 are arranged on the first hexagonal bolt 10.

[0060] like Figure 1 and Figures 4 to 9As shown, the base support structure 19 is welded with four H-shaped steels, including two cross beams and two longitudinal beams. The top of the base support structure 19 is provided with a through hole for cooperating with the first hexagonal bolt 10. The bottom of the base support structure 19 is fixedly connected to the transition plate 24 by the fourth hexagonal bolt 26, and the fourth hexagonal bolt 26 is provided with a third washer 11 and a third spring washer 12. Similarly, the bottom of the base support structure 19 has a through hole that cooperates with the fourth hexagonal bolt 26. In other embodiments 19, the bottom of the base support structure 19 can be welded to the transition plate 24, and in this case, the stable connection between the base support structure and the transition plate 24 can also be achieved. The transition plate 24 is welded on the embedded iron foundation to ensure that the base support structure 19 is fixedly fixed. In order to ensure the reliable support of the base support structure 19, a plurality of ribs are welded inside the base support structure 19.

[0061] In other embodiments, multiple longitudinal beams may be provided to adapt to a more complex support structure, or multiple transverse beams may be provided to ensure a reliable support structure even when the support structure is wider. Accordingly, the number of H-shaped steels constituting the transverse beams or longitudinal beams needs to be adjusted accordingly.

[0062] In other embodiments, the base support structure may also be formed by welding I-beams or plates.

[0063] In other embodiments, if the leg welding, bracket welding or base support structure itself has high hardness and can withstand high pressure, or if the weight of the disconnector and busbar terminal is light, no ribs or a small number of ribs may be provided.
