Description

Technical Field

[0001] The present invention belongs to but is not limited to the technical field of power distribution systems, and in particular relates to a power module frame structure system and method. Background Art

[0002] With the development of technologies and applications such as AI and supercomputing, artificial intelligence computing centers and supercomputing centers will also usher in a construction boom, promoting the rapid development of data centers. Data centers carry all digital services and connections, which is of great significance. However, traditional data center construction solutions face multiple challenges such as long construction period, high construction uncertainty, high energy consumption, difficult expansion, and low intelligence, which cannot meet the development requirements of data centers in the new era. Even after completion, design and construction problems caused by the growth of business demand, expansion of data center capacity, and expansion or renovation of existing facilities are difficult to solve.

[0003] Prefabricated power modules are an innovative form of data center power distribution system construction. From the design to the construction stage, the entire process adheres to the concept of "standardized design, factory processing, and prefabricated construction". Modular design is used to decompose the data center power supply and distribution into multiple prefabricated structures and then prefabricate and assemble the power supply and distribution system (including transformers, low-voltage mains incoming line cabinets, busbar cabinets, power factor compensation cabinets, feeder cabinets, etc.). Through the integration of electrical primary and secondary equipment, large-scale production, integrated debugging, and modular distribution are maximized, reducing on-site installation, wiring, and debugging work, effectively improving construction quality and efficiency, shortening the deployment time on the construction site, and improving the predictability of system performance.

[0004] Currently, prefabricated power modules come in many forms, mainly three typical types: standardized container type, closed appearance type, and skid type. The skid-type power module is permanently installed on a frame, sliding base or metal pallet during the manufacturing stage, so that the entire set of equipment can be transported and used as a whole unit, which is safer and more convenient. Because the components lack protection against outdoor environmental factors, this type of power module is usually installed indoors. Compared with closed appearance and ISO standardized container-type power modules, skid-type power modules have fewer capacity restrictions and can support data centers with larger capacities. Compared with traditional deployment methods, prefabricated skid-type power modules also have certain advantages in terms of cost.

[0005] The main technical point of the skid-type power module is to solve the problem of UPS footprint. The UPS cable routing is divided into upper routing and lower routing. The present invention designs the frame structure of the skid-type power module based on the upper routing form, which effectively solves the shortcomings of the lower routing UPS cable, such as poor heat dissipation performance and difficult maintenance.

[0006] In view of the above analysis, the problems and defects of the prior art are as follows:

[0007] (1) Compared with the skid-type power module, other forms of prefabricated power modules have many problems such as high investment cost, large footprint, and high transportation cost. The present invention uses the power module frame structure design to permanently fix the low-voltage switchgear and UPS on the frame, which has certain advantages in terms of cost and occupies a smaller area.

[0008] (2) The power module based on the downward wiring form has poor cable heat dissipation performance and high operation and maintenance costs. The present invention uses a frame to form an upward wiring form, which greatly solves the UPS cable heat dissipation problem and is more convenient for maintenance. Summary of the invention

[0009] In view of the problems existing in the prior art, the present invention provides a power module frame structure system.

[0010] The present invention is implemented as follows: a column support method for a power module frame structure system includes the following steps: the columns of the frame are made of 100×100×5mm Q235B square steel pipes, the columns are connected in an oblique support form by square steel pipes of the same specification, and the welding joints are fully welded by groove welding, thereby enhancing the shear and torsion resistance of the frame and ensuring the strength and stability of the structure during operation and load-bearing.

[0011] Furthermore, the steps are included: adding wire binding beams to the cable routing rack, laying the input and output cables in layers, controlling the span within 800 mm, and adjusting the cable length through a C-shaped steel cable fixing bracket to reduce the cable impedance deviation and ensure the safety and reliability of the cable under high load operation.

[0012] Furthermore, the steps are included: installing removable mesh panels before and after the power module, maintaining the mesh panel opening rate at 40%, fixing the mesh panels on the frame by latches, and maintaining the maintenance space greater than or equal to 500mm, so that operators can obtain sufficient working space during maintenance, while ensuring the heat dissipation effect of the system.

[0013] Further, the steps are included: extending the grounding busbar in the low voltage cabinet to the rear of the UPS cabinet, and fixing the grounding busbar to the beam of the frame using sheet metal parts to ensure the safety of the grounding electrical connection of the power module system and improve the stability of the overall electrical operation of the system.

[0014] The present invention also provides a power module frame structure system. The power module is mainly composed of a low-voltage cabinet, a UPS, a frame, a mesh plate, and a cable. The overall frame of the power module is composed of square steel pipes and steel plates. The welding between all columns and the bottom frame, and between the columns and the secondary beams adopts groove welding, and the weld is fully welded to ensure the welding strength.

[0015] Furthermore, the foundation base is made of 150×150×5mm Q235B square steel pipe. The thickness of the UPS cabinet is inconsistent with that of the low-voltage switch cabinet, and the rear base of the UPS cabinet is sealed with a 4mm steel plate.

[0016] Furthermore, the frame columns are made of 100×100×5mm Q235B square steel pipes, and square steel pipes of the same specifications are also used between the two columns to provide oblique support for the columns.

[0017] Furthermore, the upper cable routing rack adds wire binding beams for the cable outlet position, and the input and output cables are laid in layers. The span is controlled within 800mm, and additional reinforcement plates are added between the two layers of routing racks.

[0018] Furthermore, the frame base is embedded with telescopic lifting lugs to facilitate the handling and lifting of the power module.

[0019] Furthermore, a C-shaped steel cable fixing bracket is added above the UPS cabinet, which not only fixes the cable, but also adjusts the cable length and maintains the cable impedance deviation through the bracket.

[0020] Furthermore, after the grounding busbar in the low-voltage cabinet is extended to the UPS cabinet, the grounding busbar is fixed to the beam using sheet metal parts.

[0021] Furthermore, the front and rear maintenance parts of the power module adopt removable mesh panels, the maintenance space is greater than or equal to 500mm, the opening rate is maintained at 40%, and latches are installed on the mesh panels to fix them to the external frame.

[0022] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0023] First, the advantages of the present invention include:

[0024] 1. Good heat dissipation performance: Compared with the UPS cable down-line form, this solution solves the problem of poor heat dissipation performance of down-line cable through temperature simulation and mesh plate opening rate calculation.

[0025] 2. Easy inspection and maintenance: The mesh plate is detachable, and the inspection space is not less than 500mm, which fully facilitates the operation and maintenance personnel to conduct later inspections.

[0026] 3. Save grounding cable costs: By optimizing the grounding busbar inside the power module, a single 2500kVA power module saves about 150m of grounding cable, greatly saving the cost of grounding cables.

[0027] 3. Reliable and beautiful: The power module adopts prefabricated intelligent power distribution equipment. On the basis of modularization and standardization, it integrates the power supply and distribution system, feeding system, monitoring and management system, etc. All units provide 2N redundant configuration to improve the safety and reliability of the system and ensure the consistency of the system appearance and structure.

[0028] 4. Save space: Compared with the traditional UPS system, the centralized design makes the overall structure compact, reduces the number of distribution cabinets, and saves more than 1 times the space.

[0029] 5. Save electricity: The reduction in the number of distribution cabinets shortens the link, and the full-link UPS efficiency can reach 95.8%, which can effectively reduce power loss.

[0030] 6. Shorten the cycle: The delivery cycle is shortened from 2 months to 2 weeks. The traditional power supply solution requires on-site connection of copper busbars and cables, which has high engineering quality risks and a long cycle, and it takes 2 months to complete the delivery. The internal connection of the power module is prefabricated and debugged in the factory, and the on-site construction can be completed in 2 weeks, which helps customers to quickly launch their business.

[0031] Second, the expected benefits and commercial value of the technical solution of the present invention after transformation are:

[0032] In terms of expected benefits, the present invention greatly reduces the space occupied by the power module through the design of the frame structure, making the overall structure more compact; and saves investment costs through the design optimization of the grounding busbar.

[0033] In terms of commercial value, it has largely solved the problems of poor heat dissipation performance and inconvenient maintenance of UPS cables; the structure is simple and compact and can be mass-produced.

[0034] The technical solution of the present invention solves the technical problems that people have been eager to solve but have never been able to solve successfully:

[0035] The present invention uses centralized design and factory prefabrication installation, so that the power module occupies a smaller area and the deployment cycle is further shortened.

[0036] Third, the technical solution of the present invention solves several key problems in the prior art in industrial applications and has achieved significant technical progress, which is specifically reflected in the following aspects:

[0037] 1. Improved structural stability and load-bearing capacity: The power module frame system in the prior art is prone to structural deformation or instability when carrying a large load. The present invention adopts full-welding processing with groove welding and adds a diagonal support design between the columns, which significantly enhances the shear and torsion resistance of the frame and improves the structural stability and safety of the system during operation and transportation.

[0038] 2. Optimization of cable layout: Traditional cable laying methods easily lead to cable confusion and large impedance deviation, which affects the system operation efficiency. The present invention adds binding beams to the cable routing rack and lays cables in layers, reasonably controls the cable span, and adjusts the cable length through cable fixing brackets, which significantly reduces impedance deviation, optimizes cable layout, and improves the stability and efficiency of the system when running under high load.

[0039] 3. Improved convenience of maintenance and overhaul: In the prior art, the power module has insufficient overhaul space, and the overhaul process is complicated and cumbersome, which affects the system maintenance efficiency. The present invention not only provides convenient overhaul conditions by designing a detachable mesh plate and maintaining sufficient overhaul space, but also enhances the heat dissipation effect of the system through the design of the mesh plate, thereby improving the long-term stability and service life of the equipment.

[0040] 4. Improved system safety and electrical connection reliability: In the prior art, the layout of the grounding busbar is relatively scattered, which easily causes unstable grounding. The present invention extends the grounding busbar in the low-voltage cabinet to the rear of the UPS cabinet and fixes the grounding busbar with sheet metal parts, thereby ensuring the grounding safety of the system and the stability of the electrical connection, and reducing the risk of electrical failure during system operation.

[0041] In summary, the present invention not only solves the technical problems in the prior art, but also achieves significant technical progress in the structural strength, operation stability, maintenance convenience and electrical safety of the power module, and has good industrial application prospects.

[0057] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0058] The working principle of the power module frame structure system provided by the embodiment of the present invention is specifically as follows:

[0059] First, the overall design of the power module frame is mainly composed of square steel tubes and steel plates. The columns and secondary beams are welded by grooves and full welding to ensure welding strength. This connection method can ensure that the frame has sufficient load-bearing capacity and structural stability during transportation, installation and operation. Especially during handling and hoisting, the embedded telescopic lifting lugs further enhance the portability and flexibility of the frame, making the movement and position adjustment of the power module more convenient.

[0060] Secondly, the frame columns are made of 100×100×5mm Q235B square steel pipes, which not only provide support for the entire frame, but also increase the frame's anti-shear and anti-torsion capabilities through diagonal support. The reasonable connection between the columns and the bottom frame and secondary beams ensures that the entire system can maintain high strength under different stresses, while keeping the overall deformation of the frame within a reasonable range, thereby effectively supporting the internal power equipment, such as low-voltage cabinets and UPS cabinets.

[0061] In the design of the cable routing rack, the system optimizes the cable layout by adding binding beams and additional reinforcement plates. The input and output cables are laid in layers and the span is controlled within 800mm, which effectively avoids the stretching or bending deformation of the cables during operation. At the same time, the cable length is adjusted through the C-shaped steel cable fixing bracket to maintain the impedance deviation of the cable. This meticulous design ensures the safety and stability of the cable system during operation, especially avoiding damage or overheating of the cables during high-load operation.

[0062] Finally, the front and rear inspection parts of the power module are designed with removable mesh panels, which can provide sufficient space for equipment inspection and maintenance, ensuring at least 500mm of operating space, and provide good heat dissipation through a 40% opening rate. The mesh panels are fixed to the external frame through a latch, which is convenient for disassembly and reinstallation, improving the efficiency of daily inspection work, while ensuring that the system has sufficient ventilation and heat dissipation capacity during work, extending the service life of the equipment and improving working stability.

[0063] The main function of the power module is to convert medium voltage AC into low voltage AC to provide uninterrupted power to the load. According to the load type, it is divided into IT power module and power power module. This solution will take a single 2500kVA IT power module as an example to introduce its composition:

[0064] 1. Structural composition

[0065] like Figure 1 As shown, the power module is mainly composed of a low-voltage cabinet, a UPS, a frame, a mesh plate, a cable, etc.

[0066] 2. Overall frame structure composition

[0067] like Figure 2 As shown, the overall frame of the power module is composed of square steel pipes and steel plates. All columns and bottom frames, columns and secondary beams are welded with groove welding and full welds to ensure welding strength. See the figure below for details:

[0068] (1) Frame base

[0069] like Figure 3-Figure 6 As shown, the foundation base is calculated through load calculation and stress ratio calculation, and 150×150×5mmQ235B square steel pipe is selected. The thickness of UPS cabinet is different from that of low-voltage switch cabinet, and the rear base of UPS cabinet is sealed with 4mm steel plate.

[0070] (2) Frame columns

[0071] like Figure 7 As shown in the figure, the frame columns are calculated through hoisting conditions, and 100×100×5mm Q235B square steel pipes are selected. Square steel pipes of the same specifications are also used between the two columns to play an oblique support role for the columns.

[0072] (3) Cable routing rack

[0073] like Figure 8 As shown in the figure, there are a large number of UPS input and output cables. The upper cable routing rack is designed according to Article 6, Section 6.1.2 of GB50217 Electric Power Engineering Cable Design Standard. Wire binding beams are added to the outlet position, and the input and output cables are laid in layers with a span controlled within 800 mm.

[0074] like Fig. 9 As shown, considering the large number and weight of cables, additional reinforcement plates are added between the two layers of wiring racks.

[0075] (4) Telescopic lifting lug design

[0076] like Fig.10 As shown, considering the lifting and transportation of the power module, the frame base is embedded with telescopic lifting ears to facilitate the handling and lifting of the power module.

[0077] (5) Cable fixing bracket (C-shaped steel)

[0078] like Fig.11 As shown in the figure, the overall height of the UPS cabinet is lower than the low-voltage switch cabinet, which will result in no fixed point for the UPS cable in the vertical direction. Therefore, a C-shaped steel cable fixing bracket is added above the UPS, which can not only fix the cable, but also adjust the cable length and maintain the cable impedance deviation through the bracket.

[0079] (6) PE row fixed beam

[0080] like Fig.12 As shown, isolating and zoning the UPS and the low-voltage switch cabinet will increase the power supply distance. This solution extends the grounding busbar in the low-voltage cabinet to the back of the UPS cabinet and uses sheet metal to fix the grounding busbar to the beam, thereby saving grounding cables and costs.

[0081] (7) Mesh plate

[0082] like Figure 13-Figure 15 As shown, the front and rear maintenance parts of the power module adopt detachable mesh panels, and the maintenance space is greater than or equal to 500mm. Through cable heat dissipation simulation calculation, the opening rate is maintained at about 40%, and latches are installed on the mesh panels to fix them to the external frame.

[0083] UPS cables can also be replaced by copper busbars. Users can choose the appropriate solution based on project requirements, capacity, and scalability. The following table summarizes the characteristics of cable and copper busbar solutions.

[0084] Table 1 Comparison of cable and copper busbar solutions

[0085]

[0086]

[0087] The structure and working principle of the power module.

[0088] 1) Overall structure

[0089] The power module is mainly composed of low-voltage cabinet, UPS (uninterruptible power supply), frame, mesh plate, cable, etc. Its overall frame structure is as follows Figure 1 and Figure 2 As shown, it is made of square steel tubes and steel plates. All the welding between the columns and the bottom frame, and between the columns and the secondary beams adopts groove welding and full welding to ensure the welding strength and the stability of the overall structure.

[0090] 2) Frame base

[0091] like Figures 3 to 6 As shown in the figure, the foundation base is selected through load calculation and stress ratio calculation, and 150×150×5mm Q235B square steel pipe is used. Due to the different thickness of UPS and low-voltage switch cabinets, the rear base of the UPS cabinet is sealed with a 4mm steel plate to ensure the stability and consistency of the two.

[0092] 3) Frame columns

[0093] like Figure 7 As shown in the figure, the frame columns are calculated based on the hoisting conditions, and 100×100×5mm Q235B square steel tubes are selected. Square steel tubes of the same specifications are used for diagonal support between the two columns, which further enhances the stability and compression resistance of the columns and ensures that they will not be deformed or damaged during hoisting and use.

[0094] 4) Cable routing rack

[0095] like Figure 8 As shown in the figure, there are many UPS input and output cables. The upper cable routing rack is designed in accordance with Article 6, Section 6.1.2 of the "GB50217 Power Engineering Cable Design Standard", and a binding beam is added at the outlet position. The input and output cables are laid in layers, and the span is controlled within 800mm. Fig. 9 It shows that in order to carry more and heavier cables, additional reinforcement plates are added between the two layers of wiring racks to ensure the safe and neat laying of the cables.

[0096] 5) Telescopic lifting lug design

[0097] like Fig.10As shown, considering the lifting and transportation of the power module, the frame base is embedded with telescopic lifting lugs. The purpose of this design is to facilitate the operation of the power module during transportation and lifting, so that the entire module can be moved and installed safely and conveniently.

[0098] 6) Cable fixing bracket and PE row fixing beam

[0099] like Fig.11 As shown in the figure, since the overall height of the UPS cabinet is lower than the low-voltage switch cabinet, the UPS cable lacks fixing points in the vertical direction. Therefore, a C-shaped steel cable fixing bracket is added above the UPS, which not only fixes the cable but also adjusts the cable length and maintains the cable impedance deviation. Fig.12 In order to save grounding cables and costs, the grounding busbar in the low-voltage cabinet is extended to the back of the UPS cabinet through sheet metal parts and fixed on the beam to ensure the reliability and economy of grounding. Figures 13 to 15 As shown, the front and rear maintenance parts of the power module use detachable mesh panels to ensure that the maintenance space is greater than or equal to 500mm, and the opening rate is maintained at around 40%. Fixing to the external frame is achieved through latches to ensure cable heat dissipation and maintenance convenience.

[0100] Relevant evidence of the technical effects achieved by the embodiments of the present invention.

[0101] 1. Temperature rise test

[0102] Test the temperature rise value of the power module at 100% load rate. The entire working condition is maintained for more than 1 hour. The maximum temperature rise value is selected for each cabinet, and the actual temperature rise data of the recording temperature measuring points of other test points are recorded synchronously.

[0103] Table 1 After 20 minutes of load test

[0104] Test location UPS1 output cabinet UPS1 input cabinet UPS2 output cabinet UPS2 input cabinet Temperature value 27.6℃ 24.4℃ 25.1℃ 24.1℃

[0108] Test location Main incoming cabinet busbar UPS1 UPS3 UPS4 Temperature value 40.9℃ 34.8℃ 46.4℃ 32.6℃

[0109] At this time, the ambient temperature is 15.3℃, and the measured maximum temperature point is 46.4℃. According to the analysis of the above table, the overall temperature rise is 31.1K, which does not exceed 70K and meets the requirements.

[0110] The following are two embodiments of the present invention in industrial applications:

[0111] Example 1: Data Center Power Module Architecture

[0112] In the construction of data centers, due to the demand for a large number of servers and storage devices, the structural stability and cable management of the power module are crucial. The present invention enhances the shear and torsion resistance of the frame structure to ensure that the power module maintains good structural stability when carrying a large number of UPS and low-voltage switch cabinets. In addition, data centers usually have a large number of cable routing requirements. The cable layering and wire binding beam design of the present invention effectively reduces the problems of cable confusion and impedance deviation, ensures the safety and operating efficiency of the cable system, and significantly improves the power management level of the data center.

[0113] Example 2: Industrial Manufacturing Plant Power Module System

[0114] In large-scale industrial manufacturing plants, the layout of power equipment needs to meet the power supply requirements of high-power loads, while ensuring the stability and easy maintenance of the power module system. The power module system of the present invention ensures the stability and durability of the power modules in the plant under long-term high-power operation by adopting a frame structure with groove welding and full welding. At the same time, by designing a detachable mesh plate and reserving sufficient maintenance space, the time for equipment maintenance and overhaul can be greatly reduced, thereby improving the production efficiency of the factory. In addition, the optimization of cable routing and the improvement of the grounding system also improve the overall power system safety and operational reliability of the industrial plant.

[0115] These two embodiments demonstrate the application of the present invention in different industrial scenarios, solve the difficulties in the prior art, and significantly improve the performance and practicality of the power module system.
