Description

Technical Field

[0001] This invention relates to the field of power transmission line technology, and in particular to a movable low-voltage busbar for transformer platforms. Background Technology

[0002] When transformer equipment ages and malfunctions, or when the transformer capacity in urban construction does not meet the demand, transformer replacement is necessary. The original horizontal cable trays may obstruct the installation of the transformer, so the original horizontal cable trays must be removed first. After the transformer is installed, the cable trays need to be reinstalled. This process of removal and installation wastes a lot of time and affects the installation efficiency of the transformer. Slower transformer installation means longer power outage time, resulting in greater power outage losses. Summary of the Invention

[0003] To address the above shortcomings, this invention provides a movable low-voltage busbar for transformer platforms, which solves the problems of existing fixed low-voltage busbars, which require the removal of the original horizontal busbars when disassembling and replacing transformers, and then the busbars need to be reinstalled after the transformer is hoisted. These problems result in complex operations, long operation times, low efficiency, and significant power outage losses.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A movable low-voltage busbar for a transformer platform includes a first connecting end and a second connecting end, wherein the second connecting end and the first connecting end are rotatably connected to each other at adjacent ends, and a locking device is provided between the second connecting end and the first connecting end. When the second connecting end and the first connecting end are unfolded and parallel to each other, the locking device can lock and keep the second connecting end and the first connecting end in an unfolded and parallel state.

[0006] Furthermore, at least one of the first and second connecting ends is provided with a side-by-side latch for securing the cable.

[0007] Furthermore, the first connection end includes two first connection main boards arranged vertically and vertically, and a first connection auxiliary board located at the end of the first connection main boards;

[0008] The second connection end includes two second connection main boards arranged vertically and vertically, and a second connection auxiliary board located at the end of the second connection main boards;

[0009] The first connecting auxiliary plate and the second connecting auxiliary plate are rotatably connected.

[0010] Furthermore, a first vertical plate is provided between the two first connecting motherboards at the first connecting end, and the first vertical plate is provided with side-by-side latches for securing the cable.

[0011] Furthermore, a second vertical plate is provided between the two second connecting motherboards at the second connecting end, and the second vertical plate is provided with side-by-side latches for securing the cable.

[0012] Furthermore, the rotational connection between the first connecting auxiliary plate and the second connecting auxiliary plate is a pin connection or a hinge connection.

[0013] Furthermore, the locking device is a latch lock, which includes a latch and a bolt that cooperate with each other, one of which is located on a first connecting end and the other is located on a second connecting end.

[0014] Furthermore, the bayonet includes two opposing arc-shaped pieces, which bulge outwards in a direction away from each other to form an open annular structure.

[0015] Compared with existing technologies, the beneficial effects of this invention are: using the movable low-voltage busbar for transformer platforms of this invention, it is unnecessary to remove the original horizontal busbar when replacing the transformer, and it is unnecessary to reinstall the busbar after the transformer is hoisted, saving time wasted on disassembly and assembly, ensuring the efficiency of transformer installation, shortening power outage time, and reducing power outage losses. In other words, this invention can save working time, improve work efficiency, and avoid resource waste. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Example 1

[0026] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a movable low-voltage busbar for a transformer platform, mainly including a first connecting end 10 and a second connecting end 20. The second connecting end 20 and the first connecting end 10 are rotatably connected to each other at adjacent ends. At this time, the first connecting end 10 and the second connecting end 20 can rotate around the rotation point. A locking device is provided between the second connecting end 20 and the first connecting end 10. When the second connecting end 20 and the first connecting end 10 are unfolded and parallel to each other, the locking device can lock and keep the second connecting end 20 and the first connecting end 10 in an unfolded and parallel state.

[0027] In practice, under normal use, the movable low-voltage busbar for the transformer platform can be used as a conventional low-voltage busbar. At this time, the second connecting end 20 and the first connecting end 10 are unfolded and parallel to each other. The latch lock can lock the second connecting end 20 and the first connecting end 10, keeping them in an unfolded and parallel state. The entire low-voltage busbar is unfolded into a straight line, and the cables are placed on the low-voltage busbar. When it is necessary to replace the transformer, the locking device is opened. At this time, the second connecting end 20 and the first connecting end 10 can rotate relative to each other, such as rotating 90°. Figure 2 As shown, the cable forms a corresponding angle, thereby turning the horizontal cable busbar. This allows the cable to change direction, so that transformer replacement does not affect transformer hoisting, eliminating the need to remove the original horizontal cable busbar. After the transformer is hoisted, the cable busbar does not need to be reinstalled. Only after the transformer is hoisted, the cable busbar needs to be rotated again, so that the second connecting end 20 and the first connecting end 10 are unfolded and parallel to each other to form a straight line. A locking device is then used to lock the second connecting end 20 and the first connecting end 10 in an unfolded and parallel state. With this design, using the movable low-voltage cable busbar for transformer platforms of this invention, it is possible to replace the transformer without removing the original horizontal cable busbar, and after the transformer is hoisted, the cable busbar does not need to be reinstalled, saving time wasted on disassembly and assembly, ensuring transformer installation efficiency, shortening power outage time, and reducing power outage losses. In other words, this invention can save working time, improve work efficiency, and avoid resource waste.

[0028] In a preferred embodiment, both the first connecting end 10 and the second connecting end 20 are provided with side-by-side latches 30 for securing the cable. The latches 30 can secure the cable to the cable tray to prevent the cable from getting messy and thus serve as a storage and organization function. When it is necessary to rotate the first connecting end 10 or the second connecting end 20, the latches 30 on the first connecting end 10 or the second connecting end 20 can allow the cable to rotate together so that the cable maintains the same extension direction as the first connecting end 10 or the second connecting end 20.

[0029] Furthermore, the first connecting end 10 includes two vertically arranged first connecting main plates 11 and a first connecting auxiliary plate 12 located at the end of the first connecting main plates 11; the second connecting end 20 includes two vertically arranged second connecting main plates 21 and a second connecting auxiliary plate 22 located at the end of the second connecting main plates 21; the first connecting auxiliary plate 12 and the second connecting auxiliary plate 22 are rotatably connected, thereby realizing the rotatable connection between the first connecting end 10 and the second connecting end 20. Furthermore, the first connecting auxiliary plate 12 and the second connecting auxiliary plate 22 are connected by a hinge. A connecting frame 40 is fixedly provided at the end of the first connecting auxiliary plate 12 and the second connecting auxiliary plate 22, respectively. A hinge 50 is provided on the side of the connecting frame 40 of the first connecting auxiliary plate 12 and the second connecting auxiliary plate 22, so as to realize the rotatable connection between the first connecting auxiliary plate 12 and the second connecting auxiliary plate 22, thereby realizing the rotatable connection between the first connecting end 10 and the second connecting end 20.

[0030] Preferably, a first vertical plate 14 is provided between the two first connecting main plates 11 of the first connecting end 10, and the first vertical plate 14 is provided with side-by-side latches 30 for securing cables. In other preferred embodiments, a second vertical plate 24 is provided between the two second connecting main plates 21 of the second connecting end 20, and the second vertical plate 24 is provided with side-by-side latches 30 for securing cables. The latches 30 are arranged side-by-side on the first vertical plate 14 or the second vertical plate to realize cable routing. Exemplarily, the latches 30 include two arc-shaped pieces arranged facing each other, the two arc-shaped pieces protruding outward in a direction away from each other and forming an open annular structure. The latches 30 with open annular structure facilitate securing cables, thereby enabling the cables to be secured to the cable tray.

[0031] Please refer to Figure 1 and Figure 2 In this preferred embodiment, the latch lock includes a latch 41 and a latch 42 that cooperate with each other. One of the latch 41 and the latch 42 is disposed on the first connecting end 10, and the other is disposed on the second connecting end 20. Thus, by using the latch lock, when the latch 41 is engaged with the latch 42 (i.e., when the latch lock is engaged), the first connecting end 10 and the second connecting end 20 cannot rotate. When the latch 41 is disengaged from the latch 42 (i.e., when the latch lock is disengaged), the first connecting end 10 and the second connecting end 20 can rotate relative to each other. In this preferred embodiment, there are two latch locks, respectively disposed on the upper and lower sides of the low-voltage busbar, to ensure that the latch lock can lock the first connecting end 10 and the second connecting end 20, preventing further rotation.

[0032] Example 2

[0033] Unlike Example 1, in this preferred embodiment, please refer to... Figure 3 and Figure 4The first connecting auxiliary plate 12 and the second connecting auxiliary plate 22 are connected by a pin. The first connecting auxiliary plate 12 and the second connecting auxiliary plate 22 are stacked on top of each other and a pin is provided between them so that the first connecting auxiliary plate 12 and the second connecting auxiliary plate 22 can rotate relative to each other, thereby realizing the rotational connection between the first connecting end 10 and the second connecting end 20.

[0034] Using the movable low-voltage busbar for transformer platforms of this invention, it is unnecessary to remove the original horizontal busbar when replacing the transformer, and it is also unnecessary to reinstall the busbar after the transformer is hoisted. This saves time wasted on disassembly and assembly, ensures the efficiency of transformer installation, shortens power outage time, and reduces power outage losses. In other words, this invention can save working time, improve work efficiency, and avoid resource waste.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
