Description

Technical Field

[0001] This invention relates to the field of power modular substation technology for data centers, and in particular to an integrated layout method and system for the low-voltage system of power modular substations for data centers. Background Technology

[0002] One pain point of containerized power distribution substations for data centers is that while the low-voltage equipment inside the container can be pre-installed and tested on the assembly line, the low-voltage cabinets and access switches cannot be pre-wired because they are located in the building's low-voltage electrical room. The low-voltage cable trays must be laid to the building's low-voltage electrical room only after the power distribution substation is installed. Currently, with rapid business growth, the existing data center cannot meet the increased power supply capacity of the cabinets inside the building. Furthermore, the design and construction cycle of new data center buildings is long, failing to meet the requirements for rapid delivery. Therefore, it is necessary to install containerized power distribution substations outside the building to achieve rapid power supply and delivery. However, under traditional low-voltage cabling methods, if rapid installation and delivery are required, the on-site cabling process cannot match the time requirements. Even with ample delivery time, the advantages of modular deployment in containerized substations are not fully utilized, making it difficult to meet customer requirements. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the existing technology has the disadvantage that if rapid installation and delivery are required, the on-site wiring process cannot match the time requirements, and even if the delivery time is sufficient, the advantages of modular deployment of the modular container are not fully utilized. To this end, we propose an integrated layout method and system for the weak current system of the data center power modular container substation.

[0004] To achieve the above objectives, this application adopts the following technical solution: A method for integrated layout of low-voltage systems in a data center power substation, comprising: S1: configuring low-voltage cabinets, low-voltage boxes, or low-voltage junction boxes with low-voltage terminal blocks within the power substation, constructing an installation platform for the low-voltage equipment, and connecting it to power supply; S2: deploying an aggregation switch in the low-voltage room within the building to construct a centralized aggregation hub for low-voltage signals; S3: selecting the deployment location of the access switch according to actual needs; if deployment within the power substation is selected, proceed to S4; if deployment in the low-voltage room within the building is selected, proceed to S6; S4: placing the access switch within the low-voltage substation of the power substation... In the cabinet or low-voltage box, the access switch is connected to the low-voltage equipment in the cabin via a terminal communication cable, and the terminal communication cable is neatly arranged in the prefabricated low-voltage cable trough; S5: After the power cabin is transported to the site, the communication optical cable is led out from the access switch and connected to the aggregation switch in the low-voltage room of the building to complete the connection; S6: A low-voltage junction box with a low-voltage terminal block is set in the power cabin to aggregate the terminal communication cables of all low-voltage equipment in the power cabin to the low-voltage terminal block, and the terminal communication cables are neatly arranged in the prefabricated low-voltage cable trough; S7: After the power cabin is transported to the site, the cable is connected from the low-voltage terminal block to the low-voltage cabinet in the low-voltage room to complete the connection.

[0005] Furthermore, the terminal communication cable described in S4 does not require additional breakpoints. The switch is placed inside the power distribution box, and the terminal communication cable has a short transmission distance, which reduces signal attenuation, improves communication stability, and the absence of additional breakpoints reduces the difficulty of troubleshooting and facilitates later maintenance.

[0006] Furthermore, when the power distribution unit is deployed in a northern environment without heating, the access switch in the S4 layout scheme adopts an industrial-grade switch that supports operation at temperatures as low as -30 degrees Celsius, adapting to extreme low-temperature conditions, avoiding equipment downtime due to low temperatures, and ensuring stable system operation in cold northern regions.

[0007] Furthermore, the terminal communication cable described in S6 needs to have a break point added inside the junction box. The terminal communication cable has a long laying distance. By using terminal blocks to aggregate the cables, it is convenient to centrally manage the remote deployment scenario of the access switch and reduce the chaos of long-distance cabling.

[0008] Furthermore, the low-voltage cable trays and equipment in S4 and S6 are all prefabricated and installed in the factory, reducing on-site cross-operations. Standardized prefabrication ensures consistent processes and significantly shortens the on-site delivery cycle.

[0009] The integrated layout system for the low-voltage system of the power substation in the data center is used to realize the integrated layout method of the low-voltage system in the power substation of the data center, including the power substation, the low-voltage room in the building and the access switch;

[0010] The power control room is equipped with a low-voltage electrical cabinet, a low-voltage electrical box, and a low-voltage junction box with low-voltage terminal blocks, as well as a prefabricated low-voltage cable tray, which together serve as the carrier for the installation of low-voltage equipment and cable connection. The low-voltage room in the building is equipped with a convergence switch.

[0011] Furthermore, when the access switch is installed in the power control room, the access switch is placed in the low-voltage cabinet or low-voltage box and connected to the aggregation switch in the low-voltage room of the building through the communication optical cable. The access switch is connected to the low-voltage equipment in the room through the terminal communication line. The terminal communication line is neatly arranged in the prefabricated low-voltage cable tray, realizing the prefabricated connection of the equipment in the room. Only optical cable connection is required on site, which improves the deployment efficiency. The cable tray neatly arranges the cables and reduces electromagnetic interference.

[0012] Furthermore, when the access switch is installed in the building's low-voltage electrical room, the low-voltage junction box with low-voltage terminal blocks in the power compartment is connected to the access switch via field cables. The access switch is then connected to the aggregation switch. The low-voltage junction box is connected to the low-voltage electrical equipment in the compartment via terminal communication lines. The terminal communication lines are neatly arranged in prefabricated low-voltage cable trays. The access switch centrally manages the equipment, which is convenient for building maintenance. The combination of terminal blocks and cable trays reduces the difficulty of on-site wiring.

[0013] Furthermore, the low-voltage junction box with low-voltage terminal blocks inside the power control room has no equipment and is only used for line connection. It requires no maintenance or operating space and is installed in the top area of ​​the power control room, saving internal space. The top installation keeps it away from dust and moisture, reducing the risk of cable damage. The lack of maintenance space simplifies the internal layout of the room.

[0014] Furthermore, the low-voltage cable trays and equipment in the power control box are all prefabricated and installed in the factory. This is used to organize the terminal communication lines and the prefabricated cables between the access switches, low-voltage boxes and low-voltage terminal blocks, and to complete the cable and equipment adaptation in advance, avoiding on-site cutting and wiring. Factory commissioning can identify problems in advance and ensure successful deployment on site the first time.

[0015] The technical effects and advantages of this invention are as follows: This invention provides two deployment options for access switches: one inside the power control room and the other inside the building's low-voltage electrical room. Key equipment and low-voltage cable trays are prefabricated in the factory, requiring only fiber optic or cable connections on-site. This ultimately shortens the delivery cycle, improves communication stability, and reduces maintenance difficulty. It solves the problem that in traditional low-voltage cabling, if rapid installation and delivery are required, the on-site cabling process cannot meet time constraints. Even with ample delivery time, the advantages of modular deployment within the control room are not fully utilized, making it difficult to meet customer requirements. Attached Figure Description

Detailed Implementation

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figures 1-4As shown, to address the issue that traditional low-voltage cabling methods, when rapid installation and delivery are required, cannot keep up with time constraints, and even with ample delivery time, fail to fully leverage the advantages of modular deployment in prefabricated modular units, thus failing to meet customer requirements, the following preferred technical solutions are provided:

[0020] The integrated deployment method for the low-voltage system in a data center power substation includes: Step 1: Configuring low-voltage equipment cabinets, low-voltage boxes, or low-voltage junction boxes with low-voltage terminal blocks within the power substation to build the installation platform for the low-voltage equipment and connect it to the power supply; Step 2: Deploying an aggregation switch in the low-voltage room within the building to construct a centralized aggregation hub for low-voltage signals; Step 3: Selecting the deployment location of the access switch according to actual needs. If deployment within the power substation is selected, proceed to Step 4; if deployment in the low-voltage room within the building is selected, proceed to Step 6; Step 4: Placing the access switch in the low-voltage equipment cabinet or low-voltage box within the power substation, and connecting it to the power supply. Step 5: After the power supply unit arrives on site, extend the communication fiber optic cable from the access switch and connect it to the aggregation switch in the building's low-voltage electrical room to complete the connection. Step 6: Install a low-voltage junction box with low-voltage terminal blocks in the power supply unit to aggregate the terminal communication cables of all low-voltage electrical equipment in the power supply unit to the low-voltage terminal blocks, with the terminal communication cables neatly arranged in the prefabricated low-voltage electrical cable trough. Step 7: After the power supply unit arrives on site, connect the cables from the low-voltage terminal blocks to the low-voltage electrical cabinet in the low-voltage electrical room to complete the connection.

[0021] In step four, no additional breakpoints are needed in the end-point communication cable. The switch is placed inside the power distribution unit, and the transmission distance of the end-point communication cable is short. This reduces signal attenuation, improves communication stability, and the absence of additional breakpoints reduces the difficulty of troubleshooting and facilitates later maintenance.

[0022] When the power distribution unit is deployed in a northern environment without heating, the access switch in step four of the deployment plan should be an industrial-grade switch that supports operation at temperatures as low as -30 degrees Celsius. This adapts to extreme low-temperature conditions, prevents equipment from shutting down due to low temperatures, and ensures stable system operation in cold northern regions.

[0023] In step six, a break point needs to be added to the end communication cable inside the junction box, as the end communication cable has a relatively long laying distance. Using terminal blocks to aggregate the cables facilitates centralized management in remote deployment scenarios of access switches, reducing the clutter of long-distance cabling.

[0024] In steps four and six, the low-voltage cable trays and equipment are all prefabricated and installed in the factory. This shifts most of the low-voltage wiring work to the factory, reducing on-site overlap and ensuring consistent processes through standardized prefabrication, significantly shortening the on-site delivery cycle.

[0025] The integrated layout system for low-voltage systems in data center power substations is used to realize the integrated layout method of low-voltage systems in data center power substations. It includes a power substation, a low-voltage room in the building, and an access switch. The power substation is equipped with low-voltage cabinets, low-voltage boxes, and low-voltage junction boxes with low-voltage terminal blocks, as well as prefabricated low-voltage cable trays, which together serve as the carrier for the installation of low-voltage equipment and cable connection. The low-voltage room in the building is equipped with an aggregation switch.

[0026] When the access switch is installed inside the power control room, it is placed in a low-voltage electrical cabinet or box and connected to the aggregation switch in the building's low-voltage electrical room via fiber optic cable. The access switch also connects to the low-voltage electrical equipment inside the control room via end-point communication lines, which are neatly arranged within prefabricated low-voltage cable trays. This prefabricated connection of equipment within the control room requires only fiber optic cable splicing on-site, improving deployment efficiency. The neat cable trays also reduce electromagnetic interference.

[0027] When the access switch is installed in the building's low-voltage electrical room, the low-voltage junction box with low-voltage terminal blocks in the power control room is connected to the access switch via field cables. The access switch is then connected to the aggregation switch. The low-voltage junction box is connected to the low-voltage electrical equipment in the control room via terminal communication lines, which are neatly arranged within prefabricated low-voltage cable trays. Centralized management of the access switch facilitates building maintenance, and the combination of terminal blocks and cable trays reduces the difficulty of on-site wiring.

[0028] The low-voltage junction box with low-voltage terminal blocks inside the power control room has no equipment; it is only used for line connection and requires no maintenance or operating space. It is installed in the top area of ​​the power control room. This saves internal space, and the top installation keeps it away from dust and moisture, reducing the risk of cable damage. The lack of maintenance space simplifies the internal layout of the room.

[0029] The low-voltage cable trays and equipment within the power distribution cabin are all prefabricated and installed in the factory. These prefabricated cables are used to organize end-point communication lines and access switches, low-voltage boxes, and low-voltage terminal blocks. Pre-component cable and equipment compatibility is completed, avoiding on-site wiring cuts; factory commissioning identifies and resolves problems beforehand, ensuring successful deployment on the first attempt.

[0030] Specifically, firstly, at the factory stage, the deployment mode of the access switches is determined based on project requirements. If ultra-fast delivery is prioritized, deployment within the prefabricated control room is chosen; if centralized equipment management is emphasized, deployment in the building's low-voltage electrical room is selected. Subsequently, the positioning and installation of low-voltage cabinets, boxes, or junction boxes with terminal blocks are completed in the factory. Prefabricated low-voltage cable trays are laid simultaneously, and the access switches are fixed in the cabinets or enclosures. End-point communication lines connect to low-voltage equipment such as video surveillance and access control systems within the control room, forming an integrated prefabricated module of equipment carrier cables. Power-on testing is then completed. This process transfers most of the low-voltage electrical work to the standardized factory operating environment, not only avoiding the differences in workmanship associated with manual wiring on-site and ensuring neat cable layout via cable trays to reduce electromagnetic interference, but also allowing for early detection of equipment compatibility and line continuity issues, significantly reducing the later system failure rate and laying the foundation for rapid on-site delivery.

[0031] Secondly, for deployment within a modular facility, only a fiber optic cable is needed to directly connect the access switch inside the facility to the aggregation switch in the building's low-voltage electrical room, establishing a signal link between the access switch and aggregation switch. Because the access switch and low-voltage equipment are connected in close proximity, the transmission distance is short with no additional breakpoints, signal attenuation is minimal, communication is stable, and on-site connection can be completed in a very short time. Compared to traditional on-site full-process construction, this significantly shortens the construction period, perfectly meeting the needs of data center emergency power supply and capacity expansion.

[0032] If the deployment solution is for the low-voltage room inside the building, the terminal blocks of the junction box inside the cabin are connected to the access switch inside the building through field cables to form a link between the terminal blocks of the equipment inside the cabin and the aggregation switch. This design greatly reduces the chaos of long-distance cabling by aggregating the cables through the terminal blocks, making it easier for maintenance personnel inside the building to centrally manage the equipment and enhancing the adaptability of the solution to different management needs.

[0033] Because the low-voltage junction box is used only for wiring connections and has no built-in equipment, no maintenance or operation space is required. It can be installed on the top of the shelter, saving a significant amount of usable space inside and keeping it away from dust and moisture to extend cable life. Furthermore, standardized labeling during factory prefabrication significantly reduces troubleshooting time and lowers maintenance costs. For northern environments without heating, the shelter deployment solution uses industrial-grade switches that support low-temperature operation, ensuring stable system operation in extreme environments and further expanding the solution's applicability.

[0034] By configuring low-voltage cabinets, low-voltage boxes, or junction boxes with terminal blocks within the power control room, two deployment options are provided for the access switch: either within the control room or in the building's low-voltage room. Key equipment and low-voltage cable trays are prefabricated in the factory, requiring only fiber optic or cable connections on-site. This ultimately shortens the delivery cycle, improves communication stability, and reduces maintenance difficulty. It solves the problem that in traditional low-voltage cabling models, if rapid installation and delivery are required, the on-site cabling process cannot match the time requirements. Even with ample delivery time, the advantages of modular control room deployment are not fully utilized, making it difficult to meet customer requirements.

[0035] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
