Description

Technical Field

[0001] This utility model relates to the field of data center computer rooms, and more specifically, to a movable flexible dense busbar flange structure. Background Technology

[0002] In current high-reliability power supply systems for data centers, dense busbars, as core infrastructure for transmitting high currents, are crucial for achieving the strategic goal of "uninterrupted power supply during earthquakes." The industry generally adopts a collaborative earthquake-resistant mechanism of "load transfer - displacement compensation - energy absorption - rigid constraint," which uses seismic bracing to transfer seismic forces to the building's load-bearing structure at multiple points and utilizes elastic elements integrated into the bracing to absorb energy, thus protecting the busbars and supporting structures from damage. This technical approach has become the mainstream solution for seismic design of data centers.

[0003] However, this solution still has a critical weakness: when the compact busbar is connected to the distribution cabinet via flanges, it uses the traditional method of directly and rigidly connecting the phase busbar and PE busbar (the conductive grounding busbar of the protective grounding conductor) to the copper busbar inside the cabinet. During an earthquake, the compact busbar is constrained and fixed to the building ceiling by seismic bracing, while the distribution cabinet is fixed to the ground, resulting in significant relative displacement between the two. The existing rigid connection structure cannot effectively compensate for this displacement difference, leading to huge stress concentrations at the connection point, which can easily cause cracking or breakage, ultimately resulting in power outages. This presents a significant contradiction with the high reliability requirements of data centers. While the existing seismic bracing system can protect the busbar itself, it fails to address the seismic vulnerability of this critical connection point.

[0004] Therefore, one or more structural solutions with certain universality are needed to solve the above problems. It should be noted that the information in the background section of this utility model is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0029] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, apparatuses, steps, etc., can be employed. In other instances, well-known structures, methods, apparatuses, implementations, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0030] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, or in one or more software-hardened modules, or in different network and / or processor devices and / or microcontroller devices.

[0031] In this example embodiment, a movable, flexible, dense busbar flange structure is first provided, with reference to... Figure 1 As shown, this movable flexible busbar flange structure is used to connect a busbar and a distribution cabinet. It is characterized by comprising a flange head 100, a flange collar 200, a flexible flange grounding bar 300, and a flexible flange phase bar 400, wherein:

[0032] The flange head 100 is used for fixed connection with the dense busbar;

[0033] The flange collar 200 is used to be fixedly connected to the starting box of the distribution cabinet by fasteners;

[0034] The flexible flange grounding busbar 300 includes a first upper copper busbar 310, a first lower copper busbar 320, and a first flexible copper strip 330, which are used to realize the electrical connection between the dense busbar and the grounding terminal of the distribution cabinet;

[0035] The flexible flange phase bus 400 includes a second upper copper bus 410, a second lower copper bus 420, and a second flexible copper strip 430, which are used to realize the electrical connection between the dense busbar and the conductive copper busbar of the three-phase AC power and neutral line in the distribution cabinet.

[0036] During an earthquake, because the busbars are fixed to the building's ceiling via seismic bracing, while the distribution cabinet is fixed to the building's ground, neither is prone to displacement. Therefore, the connection point between them (where the flange is located) is subjected to extreme stress and is highly susceptible to cracking. Therefore, in this example of the utility model, as... Figures 1 to 2 As shown, the original rigid busbar flanges were replaced with flexible busbar flanges. The flexible structure provides deformable space to prevent the connection point (flange) between the busbar and the distribution cabinet from breaking during an earthquake.

[0037] An exemplary embodiment of this utility model provides a movable flexible busbar flange structure for connecting a busbar to a distribution cabinet. It is characterized by comprising a flange head, a flange collar, a flexible flange grounding busbar, and a flexible flange phase busbar. The flange head is used for fixed connection to the busbar. The flange collar is used for fixed connection to the starting box of the distribution cabinet via fasteners. The flexible flange grounding busbar includes a first upper copper busbar, a first lower copper busbar, and a first flexible copper strip, used to achieve electrical connection between the busbar and the grounding terminal of the distribution cabinet. The flexible flange phase busbar includes a second upper copper busbar, a second lower copper busbar, and a second flexible copper strip, used to achieve electrical connection between the busbar and the conductive copper busbars of the three-phase AC power and neutral line within the distribution cabinet. This embodiment of the utility model utilizes the flexible structure of the flexible busbar to provide deformable space, ensuring displacement compensation under dynamic loads during earthquakes and reducing the impact force on the busbar.

[0038] The following will further describe a movable, flexible, dense busbar flange structure in this example embodiment.

[0039] In the embodiments of this example, as Figure 5 As shown, a flexible copper foil is formed by laminating multiple layers of tin-plated copper foil together and then using molecular diffusion welding.

[0040] Molecular diffusion welding involves heating multiple layers of tin-plated copper foil together with a high current, and then pressure welding these foils. However, such flexible copper foil can only be stretched or compressed uniaxially, resulting in poor versatility.

[0041] Therefore, in the embodiment of this example, as Figures 3-4 As shown, based on the flexible copper foil manufactured using traditional flexible connectors, the entire flexible copper foil sheet is disassembled into multiple first flexible copper strips 330 and multiple second flexible copper strips 430 of equal width. This structural design satisfies the displacement compensation requirements for dynamic loads (horizontal force, vertical force, and torque) under seismic loading.

[0042] Multiple first flexible copper strips 330 are then connected between the first upper copper busbar 310 and the first lower copper busbar 320 to form a movable flexible flange grounding busbar 300. Multiple second flexible copper strips 430 are then connected between the second upper copper busbar 410 and the second lower copper busbar 420 to form a movable flexible flange array 400.

[0043] In the embodiments of this example, as Figure 3 As shown, the first lower copper busbar 320 is also provided with a grounding bolt hole 321. By inserting a bolt into the grounding bolt hole 321, the flexible flange grounding busbar 300 is connected to the grounding terminal of the distribution cabinet. Depending on the actual site conditions, the flexible flange grounding busbar 300 can be connected to the metal box of the distribution cabinet's starting box or to a dedicated grounding terminal in the distribution cabinet.

[0044] In the embodiments of this example, as Figure 4 As shown, the second lower copper busbar 420 also has phase busbar bolt holes 421, which are used to connect the flexible flange phase busbar 400 to the conductive copper busbar of the distribution cabinet by inserting bolts into the phase busbar bolt holes 421. Preferably, different phases in the flexible flange grounding busbar 300 and the flexible flange phase busbar 400 can also be labeled. For example, the flexible flange grounding busbar 300 can be marked with yellow-green or marked with the word "grounding", phase A can be marked with yellow or L1 phase, phase B can be marked with green or L2 phase, phase C can be marked with red or L3 phase, and the neutral line can be marked with blue.

In fact, according to embodiments of this utility model, the features and functions of two or more modules or units described above can be embodied in one module or unit.
