[0002] Uninterruptible power supplies (UPS) are essential equipment in power systems, primarily used to provide uninterrupted power to electronic devices, preventing damage or data loss due to power outages or voltage fluctuations. Low-voltage distribution cabinets are devices designed to ensure the normal operation of the power system by stepping down the voltage boosted by the substation to the required voltage using distribution transformers.

[0003] The demand for rapid deployment of data center infrastructure is growing stronger, leading to a significant increase in prefabricated products. Power modules, in particular, are typically modular, where uninterruptible power supplies (UPS) and low-voltage cabinets are installed side-by-side on the same base and connected by cables.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0044] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] For ease of description, this application embodiment uses a coordinate system established by two perpendicular length directions X, depth directions Y, and vertical directions Z to illustrate cabinet 1. The direction in which multiple cabinets are arranged sequentially is the length direction (as indicated by arrow X in the figure), the direction in which functional unit compartments and equipment compartments are arranged is the depth direction (as indicated by arrow Y in the figure), and the direction in which multiple functional unit compartments are arranged is the vertical direction (as indicated by arrow Z in the figure).

[0046] A converged power distribution device is characterized in that it includes a cabinet 1, and the cabinet 1 is provided with multiple partitions, which divide the cabinet 1 into equipment compartments 2, busbar compartments and functional unit compartments;

[0047] Equipment compartment 2 is used to install power distribution equipment 21, which has a first port and a second port;

[0048] The equipment compartment 2 is provided with a first partition, which divides the equipment compartment 2 into a cable area 23, which is used to introduce cables;

[0049] Equipment compartment 2 is used to install power distribution equipment 21, which has a first port and a second port;

[0050] The equipment compartment 2 is provided with a first partition, which divides the equipment compartment 2 into a cable area 23. The cable area 23 is used to introduce cables. A vertical busbar 22 is provided in the cable area 23. The cables introduced in the cable area 23 are connected to the vertical busbar 22.

[0051] The busbar compartment and the functional unit compartment are arranged adjacent to the equipment compartment 2 in the cabinet 1 along the depth direction of the cabinet 1. The cable area 23 is located in the equipment compartment 2 on the side facing the functional unit compartment.

[0052] There is a one-to-one correspondence between the busbar compartment and the functional unit compartment. The busbar compartment is equipped with a busbar system, and the corresponding unit compartment is equipped with a switch assembly. The busbar system is connected to the vertical busbar 22 of the cable area 23 through the corresponding switch assembly. The first port and the second port of the distribution equipment pass through the first partition and are connected to the vertical busbar 22.

[0053] refer to Figure 1 , Figure 2 In this embodiment, the equipment compartment 2 can be used to install uninterruptible power supply (UPS) equipment or other power distribution equipment 21. The UPS equipment or other power distribution equipment 21 has a first port and a second port. In order to achieve the connection stability between the power distribution equipment 21 and the busbar system, a cable area 23 is divided in the equipment compartment 2 by a first partition, and a vertical busbar 22 can be provided in the cable area 23. The first port and the second port of the UPS equipment are respectively connected to the vertical busbar 22. Furthermore, the switch assembly in the functional unit compartment passes through the partition of the equipment compartment 2 and is connected to the busbar.

[0054] Through the above connection method, the cable area 23 is divided in the equipment compartment 2 by the first partition, and a vertical busbar 22 is provided in the cable area 23. The functional unit compartment, the cable area 23 and the uninterruptible power supply equipment are arranged sequentially along the depth direction of the cabinet 1, forming a close connection relationship between each functional device. This shortens the length of the power distribution device as much as possible. On the basis of shortening the length of the power distribution device, the connection structure between each device can also be shortened, which can effectively improve the connection stability between the uninterruptible power supply equipment and each functional device.

[0055] The multiple functional unit compartments include a first functional unit compartment 5 and a second functional unit compartment 6, and the multiple busbar compartments include a first busbar compartment 3 and a second busbar compartment 4. The first busbar compartment 3 and the second busbar compartment 4 are respectively provided with a first busbar system 31 and a second busbar system 41. The first functional unit compartment 5 and the second functional unit compartment 6 are respectively provided with a first switch 51 and a second switch 61. The first switch 51 and the second switch 61 are respectively connected to the first busbar system 31 and the second busbar system 41.

[0056] Optionally, the functional unit compartment includes a first functional unit compartment 5 and a second functional unit compartment 6, and the busbar compartment includes a first busbar compartment 3 and a second busbar compartment 4. The first busbar compartment 3 and the second busbar compartment 4 are respectively provided with a first busbar system 31 and a second busbar system 41. The first functional unit compartment 5 and the second functional unit compartment 6 are respectively provided with a first switch 51 and a second switch 61. The first switch 51 and the second switch 61 are respectively connected to the first busbar system 31 and the second busbar system 41.

[0057] Optionally, a third functional unit compartment and a third busbar compartment can be configured inside the cabinet 1, and a third switch and a third busbar system (not shown in the figure) can be installed in the third functional unit compartment and the third busbar compartment respectively; the staff can make adaptive adjustments according to the actual needs on site and the internal space structure of the cabinet 1.

[0058] Furthermore, other functional devices can be installed in the functional unit compartment, including instruments, current transformers, indicator lights, buttons, and expansion devices.

[0059] The first functional unit compartment 5 and the second functional unit compartment 6 are arranged sequentially along the vertical direction of the cabinet 1;

[0060] The first busbar compartment 3 can be located on the side of the first functional unit compartment 5 that is far away from the second functional unit compartment 6, and the second busbar compartment 4 can be located on the side of the second functional unit compartment 6 that is far away from the first functional unit compartment 5.

[0061] Furthermore, an auxiliary compartment 7 is provided between the first functional unit compartment 5 and the second functional unit compartment 6 along the vertical direction of the cabinet 1.

[0062] By setting an auxiliary compartment 7 between the first functional unit compartment 5 and the second functional unit compartment 6, and by setting the first busbar compartment 3 and the second busbar compartment 4 relatively far apart along the vertical direction of the cabinet 1, the mutual influence between the first busbar compartment 3 and the second busbar compartment 4 is further reduced.

[0063] Optionally, the power distribution equipment 21 may include uninterruptible power supply equipment or other power distribution equipment 21.

[0064] Optionally, a spare compartment 9 is provided inside the cabinet 1, and the spare compartment 9 is arranged adjacent to the functional unit compartment along the length of the cabinet 1.

[0065] Optionally, the spare compartment 9 includes a second partition for separating the spare compartment 9 and the equipment compartment 2 within the cabinet 1, and the second partition may be provided with heat dissipation holes.

[0066] In this embodiment, the spare compartment 9 is formed by enclosing a grounded metal plate to form an independent compartment. The second partition is provided with heat dissipation holes, so that the spare compartment 9 can be used as a ventilation compartment to meet the heat dissipation requirements of the power distribution device; or the spare compartment 9 can be used as a maintenance compartment to facilitate the maintenance of the power distribution equipment 21 in the equipment compartment 2.

[0067] Optionally, the cabinet 1 includes a front door, a rear door, side panels, a bottom panel, and a top panel 11, wherein the front door, rear door, and top panel 11 may be provided with ventilation holes; in order to meet the ventilation and heat dissipation requirements of the uninterruptible power supply equipment and the ventilation and heat dissipation requirements of various functional components in the functional unit compartment, ventilation holes may be provided on the front door, rear door, and top panel 11 of the cabinet 1, and the opening area and area of ​​the ventilation holes shall be designed to be larger than the ventilation area required by the uninterruptible power supply equipment and various functional components, so as to meet the heat dissipation requirements of the overall power distribution equipment 21.

[0068] The cabinet 1 can also be divided into secondary cable compartments 8, which are adjacent to the functional unit compartments along the vertical direction of the cabinet 1 and adjacent to the busbar compartments along the depth direction of the cabinet 1.

[0069] The secondary cable compartment 8 is formed by enclosing a grounded metal plate or insulating plate to form an independent compartment. The secondary cable compartment 8 is used to lay secondary cables, which are used to connect with the secondary cables of functional devices.

[0070] Optionally, the secondary cable compartment 8 is arranged adjacent to the functional unit compartment along the vertical direction of the cabinet 1, and adjacent to the busbar compartment along the depth direction of the cabinet 1. This makes the positional relationship between the various compartments in the overall power distribution device relatively compact, minimizing the area and volume occupied by the power distribution device.

[0071] This application also provides a method for maintaining a power distribution device, including the following steps:

[0072] Step 1: Power off the power distribution equipment 21;

[0073] Step 2: Repair the power distribution equipment 21;

[0074] Step 3: Power on the power distribution equipment 21.

[0075] Optionally, step 1 may involve powering down the power distribution equipment 21, including disconnecting the first switch 51 in the first functional unit compartment 5 and disconnecting the second switch 61 in the second functional unit compartment 6.

[0076] Optionally, the specific operation method for repairing the power distribution equipment 21 in step 2 includes disconnecting the first port and the second port of the uninterruptible power supply equipment from the vertical bus 22 respectively, and then repairing or replacing the uninterruptible power supply equipment. After the uninterruptible power supply equipment has been repaired or replaced, the first port and the second port are connected to the vertical bus 22 respectively.

[0077] Optionally, the specific operation method for powering on the distribution equipment in step 3 includes closing the first switch 51 of the first functional unit compartment 5 to detect the uninterruptible power supply equipment under energized conditions. After the detection is passed, the second switch 61 of the second functional unit compartment 6 is closed to complete the load power supply of the uninterruptible power supply equipment.

[0078] like Figure 3 As shown, an embodiment of this application provides a power distribution system that, by arranging multiple power distribution devices sequentially along the length direction, can effectively reduce the length of the power distribution system and the floor space occupied compared to existing power distribution systems, thereby achieving the goal of deploying more IT cabinets.
