Description

Technical Field

[0001] The utility model relates to the technical field of power supply, and in particular to a double-layer busbar room, a UPS cabinet and a low-voltage fusion power module, which can be used as components of a prefabricated low-voltage intelligent fusion power module for assembly and coordinated use. Background Art

[0002] With the rapid development of the digital economy, data centers, as crucial vehicles for next-generation information and communication technologies such as 5G, artificial intelligence, and cloud computing, are experiencing increasing demand. Traditional data center construction solutions suffer from large footprints, long deployment cycles, low energy efficiency, high O&M costs, uncertain reliability, and poor component compatibility. Achieving rapid rollout, environmental friendliness, flexible deployment, prefabrication, and intelligent O&M have become key objectives in next-generation data center construction. Consequently, a new generation of prefabricated power modules has emerged. These modules primarily integrate substation modules, low-voltage distribution modules, uninterruptible power supply modules, and IT / power distribution modules, achieving a fully modular design, high integration, factory-prefabricated copper busbars for interconnection, and intelligent management.

[0003] For example, Chinese invention patent application publication number CN102906358A discloses a data center solution in which switchgear cabinets are arranged in rows, with busbars connected along the bottom of each cabinet and carrying current through the rows of equipment enclosures as needed. The power distribution output is first routed to an uninterruptible power supply in the enclosure, where the power is converted to uninterruptible service. Circuit breakers above the cabinets distribute the power to their respective cabinets.

[0004] As another example, a Chinese utility model patent publication numbered CN219938028U discloses a power module and power distribution system, wherein the power module includes an input busbar, an output busbar, an internal protection unit, and a UPS. The input busbar is electrically connected to the AC input of the UPS via the internal protection unit; the input busbar is electrically connected to the AC output of the UPS via the internal protection unit; and the battery input is electrically connected to the DC input of the UPS via the internal protection unit, or to the DC input of the UPS and an external protection unit disposed outside the power module. However, such a power distribution system still has shortcomings, such as the lack of integration of the low-voltage distribution module with the UPS cabinet and the simplification of the power module's functionality.

[0005] In this traditional power distribution solution, medium-voltage distribution equipment, transformers, low-voltage distribution equipment, and uninterruptible power supplies (UPSs) are considered independent components. These devices lack interconnectivity and are physically located together. Their appearance varies, and the equipment skeletons cannot be connected in parallel. Power transmission is carried out exclusively between devices via cables, resulting in a large footprint, long on-site delivery times, and difficult maintenance. Furthermore, these existing data center construction solutions suffer from long deployment cycles, low energy efficiency, high operation and maintenance costs, uncertain reliability, and poor component compatibility. Furthermore, these solutions generally do not support ongoing maintenance of the UPSs. In certain scenarios, such as bank power distribution systems and those of critical data centers, power outages can have catastrophic consequences. This not only results in financial losses but can also significantly impact customer service and operations. Therefore, the limitations of traditional power distribution solutions are particularly pronounced in these scenarios.

[0006] For these reasons, achieving rapid rollout, environmental friendliness, flexible deployment, prefabrication, and intelligent operations and maintenance (O&M) have become key objectives for data center construction in the new era. To effectively address the challenges facing existing technologies, relevant technical personnel are hoping to improve or resolve these issues through optimized product design. Utility Model Content

[0085] The exemplary schemes of the double-layer busbar chamber, UPS cabinet and low-voltage integrated power module according to the present invention are now described in detail with reference to the accompanying drawings. The accompanying drawings are provided to present multiple embodiments of the present invention, but the accompanying drawings do not have to be drawn according to the dimensions of the specific implementation scheme, and certain features may be enlarged, removed or partially cut away to better illustrate and explain the disclosure of the present invention. Some components in the accompanying drawings can be repositioned according to actual needs without affecting the technical effect. The phrase "in the accompanying drawings" or similar terms appearing in the specification do not necessarily refer to all drawings or examples.

[0086] Certain directional terms used in the following description of the drawings, such as "inner," "outer," "upper," "lower," and other directional terms, will be understood to have their normal meanings and refer to those directions associated with normal viewing of the drawings. Unless otherwise indicated, the directional terms described in this specification are generally in accordance with conventional directions understood by those skilled in the art.

[0087] The terms "first", "first", "second", "second" and similar terms used in this utility model do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0088] As is known, in traditional power distribution solutions, medium-voltage distribution equipment, transformers, low-voltage distribution equipment, and uninterruptible power supplies are considered independent components. These devices lack interconnectivity and are only physically placed together. They have different appearances, and the equipment skeletons cannot be connected in parallel. Power transmission can only be carried out between devices via cables, resulting in large floor space, long on-site delivery times, and difficult maintenance. In particular, traditional power distribution solutions have difficulty integrating low-voltage distribution equipment and uninterruptible power supplies. This is largely due to the difficulty in currently UPS cabinets in allowing for the parallel arrangement of two busbars or copper busbars with different orientations.

[0089] exist Figure 1-3 The figure shows a low-voltage integrated power module according to the present invention, which includes a modular or separable low-voltage incoming / interconnecting cabinet 100, a reactive power compensation cabinet 200, a maintenance bypass cabinet 30, a first UPS input / output cabinet 20A, a first UPS cabinet 10A, a second UPS input / output cabinet 20B, a second UPS cabinet 10B, and a first feeder cabinet 300A and a second feeder cabinet 300B. The structures of the incoming / interconnecting cabinet 100, reactive power compensation cabinet 200, and feeder cabinets 300A and 300B are described in detail below. These cabinets are detachably connected together in the horizontal direction.

[0090] Here, the incoming / interconnecting cabinet 100 is configured to direct power from the low-voltage side of the transformer module to the integrated power module and is responsible for the current carried by the entire busbar section. The reactive power compensation cabinet 200 is configured to balance the load, improve the power factor, and thus enhance equipment utilization. It can be configured with devices such as capacitors, reactors, SVG, and APF. The UPS input / output cabinet is configured with independent circuit breakers for control and protection, enabling online maintenance of the UPS. Here, power can be input from the UPS input switch into the UPS (which houses functional switches and power modules). The internal rectifier module rectifies the AC power into DC, which is then inverted into AC by the inverter module for output, and then output to the fed load through the UPS power module output switch. Furthermore, the maintenance bypass cabinet 30 is configured to transfer the load to an external maintenance bypass when the UPS requires scheduled maintenance or a UPS failure occurs. As a feasible example, the maintenance bypass cabinet 30 may consist of components such as a bypass switch, instruments, busbars, and a housing. Since its structure is well known to those skilled in the art, it will not be described in detail here.

[0091] This prefabricated low-voltage fusion power module integrates the modular low-voltage incoming line / communication cabinet 100, reactive compensation cabinet 200, maintenance bypass cabinet 30, first UPS input / output cabinet 20A, first UPS cabinet 10A, second UPS input / output cabinet 20B, second UPS cabinet 10B and first feeder cabinet 300A and second feeder cabinet 300B. All equipment and inter-equipment connection components are prefabricated in the factory, which not only greatly reduces the floor space, but also enables rapid delivery and deployment at the customer site. This prefabricated low-voltage fusion power module supports the maintenance or replacement of the first UPS cabinet 10A and / or the second UPS cabinet 10B without powering off the system; it also has the function of expansion and rapid deployment without powering off the system, eliminating the impact of power outages; and the operation time for maintenance, replacement, and expansion is no longer restricted. The following is a further detailed introduction to each of the above components.

[0092] like Figure 2-3 As shown, the low-voltage incoming line / communication cabinet 100, the reactive power compensation cabinet 200, the maintenance bypass cabinet 30, the first UPS input / output cabinet 20A, the first UPS cabinet 10A, the second UPS input / output cabinet 20B, the second UPS cabinet 10B and the first feeder cabinet 300A and the second feeder cabinet 300B can be arranged in sequence from left to right; of course, it is also conceivable to arrange them in sequence from right to left.

[0093] The number of the first UPS input / output cabinet 20A, the first UPS cabinet 10A, the second UPS input / output cabinet 20B, the second UPS cabinet 10B, and the first feeder cabinet 300A and the second feeder cabinet 300B can be only one or more. When the number of the first UPS input / output cabinet 20A, the first UPS cabinet 10A, the second UPS input / output cabinet 20B, the second UPS cabinet 10B, and the first feeder cabinet 300A and the second feeder cabinet 300B is more than one, the multiple first UPS input / output cabinets 20A, the first UPS cabinet 10A, the second UPS input / output cabinet 20B, the second UPS cabinet 10B, and the first feeder cabinet 300A and the second feeder cabinet 300B are sequentially arranged in parallel.

[0094] Although not shown, it is conceivable that the prefabricated low-voltage integrated power module also includes modular medium-voltage incoming line switchgear. Here, the medium-voltage incoming line switchgear is detachably connected to the transformer equipment, low-voltage incoming line / connector cabinet 100, reactive power compensation cabinet 200, maintenance bypass cabinet, etc. in a horizontal direction.

[0095] In order to detachably connect the individual cabinets of the prefabricated low-voltage integrated power module, each cabinet preferably includes cabinet connection holes. These cabinet connection holes can be provided on the side walls of the cabinet frame, so that the cabinets can be fastened together through these connection holes to form a whole and then fixed to a base or a flat concrete floor at the delivery site.

[0096] In order to realize the integration of the low voltage incoming line / connection cabinet 100, the reactive power compensation cabinet 200, the maintenance bypass cabinet 30, the first UPS input / output cabinet 20A, the first UPS cabinet 10A, the second UPS input / output cabinet 20B, and the second UPS cabinet 10B, see Figure 2 It can be seen that the following technical requirements need to be coordinated and met or the following technical obstacles need to be resolved:

[0097] 1. The three-phase ABC of the first main busbar from the incoming / connecting cabinet 100 and the reactive power compensation cabinet 200 and the three-phase ABC of the second main busbar from the maintenance bypass cabinet 30 must be able to pass through the first UPS cabinet 10A and the second UPS cabinet 10B without interfering with each other;

[0098] 2. The connection busbars from the first UPS cabinet 10A and the second UPS cabinet 10B can be connected to the first UPS input / output cabinet 20A and the second UPS input / output cabinet 20B respectively without interference.

[0099] Therefore, the first UPS cabinet 10A and the second UPS cabinet 10B in the low voltage integrated power module of the present invention can be designed with Figure 4 The double busbar chamber 1010 is best shown in FIG. Figure 3As shown, the first UPS cabinet 10A and the second UPS cabinet 10B are respectively sandwiched between the first UPS input / output cabinet 20A and the second UPS input / output cabinet 20B and are constructed to allow the first main bus ABC three-phase from the incoming / connecting cabinet 100 and the second main bus ABC three-phase from the maintenance bypass cabinet 30 to pass horizontally through the double-layer bus chamber 1010 above them without interfering with each other.

[0100] like Figure 4 As shown, the double-layer busbar chamber 1010 located above the first UPS cabinet 10A and the second UPS cabinet 10B includes a Figure 4 The three cabinet front beams 1011A-C spaced parallel from bottom to top on the left side of the cabinet are Figure 4 The three rear cross beams 1012A-C spaced parallel to each other from bottom to top on the right side of the cabinet, wherein these front cross beams 1011A-C and rear cross beams 1012A-C are connected to each other by means of four C-shaped profiles 1013 located at the four corners of the cube, thereby forming a lower busbar chamber enclosed by the front cross beams 1011B-C and rear cross beams 1012B-C and a lower busbar chamber enclosed by the front cross beams 1011C-A and rear cross beams 1012C-A, wherein transversely to the extension direction of the front cross beams 1011C-A and rear cross beams 1012C-A, between the front cross beams 1011C and rear cross beams 1012C, near Figure 4 The right side of the busbar clamp installation beam 1014B is connected and is located between the front beam 1011B and the rear beam 1012B of the cabinet. Figure 4 A busbar clamp mounting beam 1014A is connected to the right side of the cabinet. Similarly, a busbar clamp mounting beam 1014D is connected approximately centered between the cabinet front beam 1011C and the cabinet rear beam 1012C, and a busbar clamp mounting beam 1014C is connected approximately centered between the cabinet front beam 1011B and the cabinet rear beam 1012B. Thus, a busbar clamp 1015B capable of traversing the three phases of the first main busbars ABC is installed between busbar clamp mounting beams 1014B and 1014A, and a busbar clamp 1015A capable of traversing the three phases of the second main busbars ABC is installed on busbar clamp mounting beam 1014A. To better support the three-phase busbars ABC and ABC, a busbar clamp 1015B for the three-phase busbars ABC is preferably installed between the busbar clamp mounting beams 1014D and 1014C. A busbar clamp 1015A for the three-phase busbars ABC is also installed on the busbar clamp mounting beams 1014C. Furthermore, the N and PE rows can be located at the rear of the cabinet.

[0101] At the same time, in order to allow the connecting busbars from the first UPS cabinet 10A and the second UPS cabinet 10B to be transmitted to the first UPS input / output cabinet 20A and the second UPS input / output cabinet 20B without interference, a busbar clamp 1015A for the connecting busbar to pass through is installed on the busbar clamp mounting beam 1014C.

[0102] exist Figure 5 The figure shows a top cover for covering or shielding external dust and other substances, wherein the top cover maintains a top plate 1016 whose size is designed to be consistent with the outer size of the UPS cabinet and a front door 1017A and a rear door 1017B protruding from both sides of the top plate 1016, wherein the front door 1017A and the rear door 1017B respectively cover or close the busbar chamber from the front and rear sides of the double-layer busbar chamber 1010 to prevent accidents.

[0103] By means of the UPS cabinet 10A and the UPS cabinet 10B with the double-layer busbar chamber 1010 designed in this way, Figure 2 and 3 It can be clearly seen that, compared with the traditional cable connection method, the full link of different busbars or copper bars in the low-voltage integrated power module can be achieved without interfering with each other. Furthermore, due to such a busbar or copper bar design, it is possible to avoid the use of known cable connection methods between the low-voltage distribution module and the UPS module. Alternatively, the two can be connected through a prefabricated all-copper busbar, which greatly shortens the deployment cycle and greatly improves efficiency. With such a design, the low-voltage distribution module and the UPS module are fully decoupled. At the same time, the use of prefabricated copper busbar connections to achieve electrical connection between the low-voltage distribution module and the UPS module is conducive to the integration of the two cabinet types, improves the safety factor and installation operation efficiency of the product, greatly shortens the deployment cycle, and can achieve safe and efficient operation and maintenance of the product.

[0104] exist Figures 6 to 15 FIG. 1 shows an incoming line connection cabinet 100 provided according to the present utility model. Figure 6 As shown, the incoming line connection cabinet 100 comprises a substantially rectangular cabinet body. The cabinet body comprises a cabinet frame and a panel. The cabinet body houses electronic devices such as circuit breakers, disconnectors, load switches, operating mechanisms, transformers, various protective devices, and cables and wires for electrically connecting the various electrical components within the cabinet body and between them and external components.

[0105] See also Figure 6 In this embodiment, the incoming connection cabinet 100 is roughly divided into three areas from top to bottom, namely the busbar chamber 101, the first area 102 and the second area 103. The busbar chamber 101, the first area 102 and the second area 103 can be interconnected in space to allow electrical connections between electrical components. Figures 7 to 8As shown, the busbar chamber 101 correspondingly accommodates a first busbar connector 108A and a second busbar connector 109A and transformers preferably arranged on the first busbar connector 108A and the second busbar connector 109A. The transformers can be used to measure one or more parameters of the current and voltage flowing through the first busbar connector 108A and the second busbar connector 109A. Other computing elements controlled and connected to the transformers can obtain parameters such as power, harmonics, and frequency based on the measured current or voltage, so as to understand the operation of the incoming line connection cabinet 100 in more detail from multiple aspects.

[0106] See again Figure 7 and 11 In the first zone 102 and the second zone 103, a first circuit breaker 104 that can be used as an incoming circuit breaker and a second circuit breaker 105 that can be used as a connecting circuit breaker are fixedly installed respectively (these circuit breakers can be 1250A frame-type circuit breakers). As an example, the main copper busbar connection terminals of the first circuit breaker 104 that serves as an incoming circuit breaker can be electrically connected to the connection terminals of the second circuit breaker 105 that serves as a connecting circuit breaker through the first busbar 108 (A, B, C phase, N phase). Figure 6-7 As shown in the figure, each phase of the first busbar 108 is electrically connected to the circuit breaker and then extends into an independent compartment of a vertical busbar with a certain thickness at the rear of the cabinet, which is separated from the circuit breaker. The four-phase busbars of phases A, B, C, and N are arranged in the same vertical direction from back to front, and then the busbar is extended upward to the busbar chamber 101 at the top of the cabinet to form a first busbar joint 108A, which is connected to the horizontal busbars of other feeder cabinets (section I busbar) to provide power for each feeder circuit; further, with the help of the rear partition plate 102C located in the first area 102, an independent compartment for the second busbar 109 that can be used as a grounding wire (PE phase) is formed between the first busbar and the rear wall of the incoming line connection cabinet 100. Here, the second busbar also extends upward to the busbar chamber 101 at the top of the cabinet to form a second busbar joint 109A.

[0107] As a feasible approach, the first circuit breaker 104 is connected to the vertical copper busbar of the incoming line ABC. The three-phase incoming line busbars (1TAa to 1TAc) of ABC are directly arranged from back to front, for example, with a phase spacing of 110 mm, and from left to right, for example, with a horizontal spacing of 90 mm. The incoming line busbar is then bent toward the front of the cabinet and extended upward to the busbar compartment at the top of the cabinet. Before bending, the busbar is broken to install the current transformer. After extending to the main busbar compartment, the NABC is extended a certain distance out of the cabinet through a horizontal copper busbar to facilitate connection of the power incoming line busbar on the low-voltage side of the transformer to this incoming line busbar.

[0108] The second circuit breaker 105 is connected to the vertical copper busbars (L21, L22, L23, N) of the interconnecting NABC. The four-phase interconnecting bars of this NABC are arranged vertically from left to right, with a horizontal spacing of, for example, 90 mm. The interconnecting bars are then positioned close to the rear of the cabinet and extended upward to the busbar compartment at the top of the cabinet. The busbars are then interrupted at the same height as the incoming copper busbars to install the current transformers (3TAa-3TAc). After extending to the main busbar compartment, they can be connected to the busbar section II via the dense busbar duct in the starting box.

[0109] After the primary electrical components within the cabinet are connected via copper busbars, the power supply circuit path for the first circuit breaker 104 of the incoming line breaker cabinet can primarily be routed through the main busbar, passing the incoming line copper busbar to the upper connector of the first circuit breaker 104, then through the circuit breaker to the lower connector of the first circuit breaker 104, and then through the vertical busbar to the horizontal busbar, connecting to the main busbars of other feeder cabinets to provide power for each feeder line. The power supply circuit path for the second circuit breaker 105 of the incoming line breaker cabinet is through the busbar duct, carrying the electricity from the II section busbar through the vertical busbar behind the cabinet to the lower terminal of the second circuit breaker 105, then through the circuit breaker to the upper terminal of the second circuit breaker 105, and then through the vertical busbar to the horizontal busbar, connecting to the main busbars (L11, L12, L13, N) of other feeder cabinets to provide power for each feeder line.

[0110] As a result, the improved incoming line contact cabinet (with dimensions changed to 700 mm wide and 2300 mm high) has both incoming line and contact functions, but the floor space occupied by a single incoming line contact cabinet is reduced by 50% compared with the existing incoming line cabinet and contact cabinet placed side by side. Such an incoming line contact cabinet not only ensures working performance but also meets the miniaturization requirements, effectively overcoming the defects of the existing technology.

[0111] See also Figure 6 The cabinet frame of the incoming line contact cabinet 100 is assembled by frame columns 111 arranged along the height direction Z direction, crossbeams arranged between the frame columns 111 and arranged along the width direction Y direction and the depth direction X direction respectively, and connectors made of aluminum, for example, for connecting them together. Here, the frame columns 111 in the frame are assembled by Figure 1 The top of the cabinet is provided with a top cabinet width beam 112 arranged along the width direction Y of the cabinet body and the bottom of the cabinet is provided with a bottom cabinet width beam 112 arranged along the width direction Y of the cabinet body. They are used as part of the above beams to connect with the frame columns. These top cabinet width beams and / or bottom cabinet width beams 112 can be Figures 21 to 25, wherein the top cabinet width beam and / or the bottom cabinet width beam 112 includes a slot 112A generally designed to be C-shaped and a first folded edge 112B or a second folded edge 112C connected thereto. Here, the first folded edge 112B for use with the first connector 400 described below has a wider width, for example, 100 mm, while the second folded edge 112C for use with the second connector 500 is narrower, for example, 50 mm.

[0112] Specifically, in Figures 21 to 29 As shown in detail in FIG, the first connecting member 400 includes a base 401 and a plurality of extensions 402A to 402C, preferably three in number. The base 401 is generally configured as a rectangular parallelepiped or a cube, and the plurality of extensions 402A to 402C are perpendicular to the base 401 and extend from the base 401 orthogonally to each other. Each extension 402A to 402C respectively engages with the slot 112A of the adjacent frame column 111 or the top cabinet width beam and / or the bottom cabinet width beam 112 to splice out the cabinet frame of the incoming line connection cabinet 100. Figures 26 to 28 As shown, the plurality of extensions 402A to 402C generally include a first extension 402A located in the longitudinal direction, a second extension 402B located in the width direction, and a third extension 402C extending perpendicular to the plane. The frame columns 111 are generally divided into horizontal supporting columns and vertical supporting columns. The horizontal columns and vertical columns are respectively connected to the plurality of extensions 402A to 402C of the first connector 400 to form the cabinet frame.

[0113] Further, in Figures 29 to 30 The second connector 500 is shown in FIG. It comprises a base 501 and preferably two extensions. The base 501 is generally configured as a rectangular parallelepiped or cube, for example. Two extensions 502A and 502B extend perpendicularly from the base 501 and orthogonally thereto. Each extension 502A and 502B engages adjacent frame columns or crossbeams to form the cabinet frame of the incoming line switch cabinet 100. The frame columns 111 are generally divided into horizontal supporting columns and vertical supporting columns. These columns and vertical columns are each engaged with the second connector 500 to form the cabinet frame.

[0114] As a non-limiting example, the first connecting member 400 and the second connecting member 500 are detachably coupled to the frame column 111, for example, by threaded connection, i.e., connecting holes are provided at corresponding positions of the horizontal portions, vertical portions, etc. of the multiple extensions 402A to 402C and the transverse columns and vertical columns of the frame column 111 for the passage of the screws, thereby achieving the positioning of the transverse columns and vertical columns of the frame column 111 relative to the first connecting member 400 and the second connecting member 500.

[0115] Thus, the incoming line connection cabinet 100 of the present invention is formed by joining the cabinet frame with the frame columns by aluminum casting connectors, so that the formed cabinet frame (and thus the incoming line connection cabinet) can prevent the formation of magnetic conductive loops in the cabinet body of the incoming line connection cabinet or promptly interrupt any magnetic conductive loops that may be formed by means of the connectors, thereby achieving welding-free assembly and effectively avoiding the generation of eddy currents, thereby achieving the beneficial effect of reducing and optimizing the heat dissipation performance of the incoming line connection cabinet. Furthermore, unlike the prior art using G-shaped or other shaped profiles, the cooperation of the crossbeam 112 and the first connector 400 and the second connector 500 according to the present invention makes the entire cabinet frame more solid and stable.

[0116] See again Figures 7 to 9 As shown, a partition 106, preferably made of stainless steel, is disposed between the busbar chamber 101 and the first zone 102 of the incoming interconnector cabinet 100. The stainless steel partition 106 may be a one-piece sheet metal member with multiple holes for controllable busbars and openings for allowing hot air to circulate between the busbar chamber 101 and the first zone 102. Above the partition 106, transversely arranged crossbeams 112 divide the busbar chamber 101 into a lower busbar chamber 101B located below and an upper busbar chamber 101A located above. The connectors 108A of the first busbar 108 and 109A of the second busbar 109 may be disposed in the lower busbar chamber 101B and the upper busbar chamber 101A, respectively, at different heights, to separate them. To facilitate the electrical connection of the busbar, different busbar clamps may preferably be provided in the lower busbar chamber 101B and the upper busbar chamber 101A to position the first busbar connector 108A and the second busbar connector 109A connected to the circuit breaker.

[0117] Unlike traditional distribution room systems, where busbar bridges are often used to connect functional switchgear, making prefabrication and installation impossible, the incoming line interconnector structure employed in this utility model allows for the connection of low-voltage switchgear of different functional types, as described in detail below, and the distribution of horizontal busbars. This paves the way for prefabricated low-voltage distribution modules in factories.

[0118] Further in Figure 7 and 11As clearly shown in Figures 14 to 15, a front partition panel 102A and a front partition panel 103A are respectively provided in the first zone 102 and the second zone 103 for electrically isolating the first circuit breaker 104 and the second circuit breaker 105 from other electrical components and the connection area in the incoming connection cabinet 100. Mounting plates 102B and 103B are respectively provided below the front partition panels 102A and 103A for mounting the first circuit breaker 104 and the second circuit breaker 105. Preferably, the front partition panels 102A and 103A have an outer shape that conforms to the inner circumferential walls of the first zone 102 and the second zone 103 and are designed as thin plates integrally formed from metal or insulating plates. The plates are provided with a plurality of openings for airflow. Compared with multi-piece partitions that need to be connected to each other by fasteners such as self-tapping screws or bolts, the front partition plates 102A and 103A of the present invention have fewer parts and a simplified assembly process, which reduces production time and improves efficiency.

[0119] like Figure 12 and 13 As shown, a busbar separator 110 is further provided behind the first circuit breaker 104 in the first zone 102. The busbar separator 110 may be a thin plate integrally formed of a metal plate or an SMC insulating plate. The busbar separator 110 is provided with a plurality of openings for air to flow through. Figure 3 As shown, busbar separator plate 110 can separate the four-phase busbars (selectably A, B, C, and N phases), which extend upward to the lower busbar chamber 101B at the cabinet top and form a first busbar joint 108A, from the upper busbar chamber 101A, which also extends upward to the cabinet top and forms a second busbar joint 109A. Unlike the prior art, which generally ignores the protection of copper busbars against electric shock, the embodiments of the present invention fully consider the internal separation of the cabinet body and achieve safe isolation between the system bus channel and equipment units through a combination of metal partitions and insulating panels, thereby improving the protection of the personal safety of operation and maintenance personnel.

[0120] As another aspect of the present invention, Figures 16 to 20 The figure shows a reactive power compensation cabinet 200 (also referred to as an SVG cabinet) provided according to the present invention, which is primarily used to regulate reactive power in power systems. As shown, the reactive power compensation cabinet 200 comprises a roughly rectangular cabinet body. The cabinet body consists of a cabinet frame and panels. The cabinet houses electronic devices such as reactive power compensation devices (reactors, capacitors), drawer units 205, and cables and wires for electrically connecting the various electrical components within the cabinet and external components.

[0121] See also Figure 16-18In this embodiment, the reactive power compensation cabinet 200 is roughly divided into three areas from top to bottom, namely, a busbar chamber 201, a first area 202, and a second area 203. The busbar chamber 201, the first area 202, and the second area 203 can be spatially interconnected to allow electrical connections between electrical components.

[0122] like Figures 17 to 19 As shown, a partition 206, preferably made of stainless steel, is disposed between the busbar chamber 201 and the first zone 202 of the reactive power compensation cabinet 200. The partition 206 and the top plate 207 above it together define the space of the busbar chamber 201. The stainless steel partition 206 can be a one-piece sheet metal member, provided with multiple holes for the controllable busbars and openings for allowing hot air to circulate between the busbar chamber 201 and the first zone 202. Above the partition 206, transversely arranged crossbeams 112 divide the busbar chamber 201 into a lower busbar chamber 201B located below and an upper busbar chamber 201A located above. The connectors for the busbars extending into the busbar chamber 201 are located in the lower busbar chamber 201B. Preferably, busbar positioning slots are provided in the lower busbar chamber 101B to facilitate the installation and securing of the busbars.

[0123] like Figures 17 to 19 As shown, a third circuit breaker 204 electrically connected to a busbar is installed within the first section 202 of the reactive power compensation cabinet 200. Similar to the incoming line switch cabinet 100, the first section 202 is equipped with a front partition plate 202A for electrically isolating the third circuit breaker 204 from other electrical components and the connection area within the reactive power compensation cabinet 200. Mounting locations for the third circuit breaker 204 are provided below the front partition plates 202A. Preferably, the front partition plates 202A have an outer shape that conforms to the inner circumferential wall of the first section 102 and are designed as thin plates integrally formed from metal or insulating sheet. The plates are provided with multiple openings for airflow. Compared to multi-piece partition plates that require fasteners such as self-tapping screws or bolts, the front partition plates 102A of the present invention have fewer parts, simplify the assembly process, reduce production time, and improve efficiency.

[0124] like Figure 16 As shown, multiple SVG compensation modules 205 or other monitoring modules can be fixedly arranged in a stacked arrangement in the second zone 203 below the first zone 202. For example, these modules can be low-voltage active filtering devices, which use high-speed DSP digital signal processing technology to drive IGBT electronic devices to inject a current into the power grid with equal amplitude and opposite phase to the original harmonic current, reducing the total harmonic current of the power supply to zero, thereby achieving real-time compensation for harmonic currents.

[0125] As an alternative embodiment, the multiple SVG compensation modules 205 stacked one above the other within the second section 203 of the reactive power compensation cabinet 200 can also be designed as drawer units, where these drawer units consist of rails and drawers mounted on the rails. The reactive power compensation cabinet 200 has a wiring channel behind these drawer units, within which are three spaced-apart busbars for three-phase wiring. The rear ends of these drawers can be equipped with secondary terminal blocks that plug into the busbars. The secondary terminal blocks are secured to the drawers via snap-fits or screws. As a feasible example, the secondary terminal blocks include a base, three movable contacts at the front end of the base, and three terminal blocks at the rear end of the base that connect to the movable contacts. These terminal blocks are used to connect to the reactive power compensation devices (reactors, capacitors, etc.) installed within the drawers. The movable contacts have U-shaped sockets at the front ends that plug into the busbars. When the drawer is inserted, the "U"-shaped socket of the moving contact is inserted into the wiring busbar to complete the wiring; when the drawer is pulled out, the "U"-shaped socket of the moving contact is away from the wiring busbar to complete the circuit breaking.

[0126] Likewise, see Figure 16 The cabinet frame of the reactive power compensation cabinet 200 is assembled by frame columns 111 arranged along the height direction Z, crossbeams arranged between the frame columns 111 and arranged along the width direction Y and the depth direction X, and connectors for connecting them together, such as those made of aluminum. Figure 11 The top of the cabinet is provided with a top cabinet width beam 112 arranged along the width direction Y of the cabinet body and the bottom of the cabinet is provided with a bottom cabinet width beam 112 arranged along the width direction Y of the cabinet body. They are used as part of the above beams to connect with the frame columns. These top cabinet width beams and / or bottom cabinet width beams 112 can be, for example, Figures 21 to 25 , wherein the top cabinet width beam and / or the bottom cabinet width beam 112 includes a slot 112A generally designed to be C-shaped and a first folded edge 112B or a second folded edge 112C connected thereto. Here, the first folded edge 112B for use with the first connector 400 described below has a wider width, for example, 100 mm, while the second folded edge 112C for use with the second connector 500 is narrower, for example, 50 mm.

[0127] Therefore, the improved reactive power compensation cabinet 200 (with dimensions of 600 mm in width and 2300 mm in height) not only ensures working performance but also meets the requirements of miniaturization, thereby effectively overcoming the defects of the prior art.

[0128] As another aspect of the present invention, Figures 31 to 35The feeder cabinet 300 provided in accordance with the present invention is shown. It is primarily used to transmit electrical energy from incoming lines to various loads (or users). As shown, the feeder cabinet 300 comprises a roughly rectangular cabinet body. The cabinet body consists of a cabinet frame and panels. The cabinet houses electronic devices such as circuit breakers and busbars, as well as cables and wires used to electrically connect the various electrical components within the cabinet and to external components.

[0129] See also Figures 31 to 35 In this embodiment, the feeder cabinet 300 is roughly divided into three areas from top to bottom, namely, the busbar chamber 301, the first area 302, and the second area 303. The busbar chamber 201, the first area 302, and the second area 303 can be spatially interconnected to allow electrical connections between electrical components.

[0130] like Figures 31 to 35 As shown, a partition 306, preferably made of stainless steel, is disposed between the busbar chamber 301 and the first zone 302 of the feeder cabinet 300. The partition 306 and the top plate 307 above it together define the space of the busbar chamber 301. The stainless steel partition 306 can be a one-piece sheet metal member, provided with multiple holes for the controllable busbars and openings that allow hot air to circulate between the busbar chamber 301 and the first zone 302. Above the partition 306, transversely arranged crossbeams 112 divide the busbar chamber 301 into a lower busbar chamber 301B located below and an upper busbar chamber 301A located above. The connector for the busbars from the fourth circuit breaker 304, described below, extending into the busbar chamber 301, is located in the lower busbar chamber 301B. Preferably, busbar positioning slots are provided in the lower busbar chamber 301B to facilitate the installation and securing of the busbars. At the same time, the connection busbar from the fifth circuit breaker 305 can be extended into the busbar chamber 301 and arranged in the upper busbar chamber 301A. Preferably, a busbar positioning groove can be provided in the upper busbar chamber 301A to play the role of installing and fixing the connection busbar.

[0131] Further in Figure 31 and 35As clearly shown in the figure, the first and second zones 302 and 303 are each provided with a front partition plate 302A and a front partition plate 303A, respectively, for electrically isolating the fourth and fifth circuit breakers 304 and 305 housed therein from other electrical components and the connection area within the feeder cabinet 300. Below the front partition plates 302A and 303A, mounting plates 302B and 303B are provided, respectively, for mounting the fourth and fifth circuit breakers 304 and 305. Preferably, the front partition plates 302A and 303A have an outer shape that conforms to the inner circumferential walls of the first and second zones 302 and 303, and are designed as thin plates integrally formed from metal plates or SMC insulation boards. Multiple openings are provided in the plates for airflow. Compared with multi-piece partitions that need to be connected to each other by fasteners such as self-tapping screws or bolts, the front partition plates 302A and 303A of the present invention have fewer parts and a simplified assembly process, which reduces production time and improves efficiency.

[0132] like Figure 35 As shown, a busbar separator 110 is further provided behind the fourth circuit breaker 304 in the first zone 302. The busbar separator 110 may be a thin plate integrally formed of a metal plate or an insulating plate. A plurality of openings for air to flow through are provided on the busbar separator 110. Figure 8 As shown, the busbar separator 110 can separate the busbars (which can be selected as phases A, B, C, and N here) that extend upward to the lower busbar chamber 301B at the top of the cabinet and form a busbar joint from another busbar that extends upward to the upper busbar chamber 301A at the top of the cabinet and forms another busbar joint. Unlike the prior art, which generally ignores the protection of copper busbars against electric shock, the embodiments of the present invention fully consider the internal separation of the cabinet body and achieve safe isolation between the system busbar channel and equipment units through a combination of metal partitions and insulating panels, thereby improving the protection of the personal safety of operation and maintenance personnel.

[0133] Likewise, see Figure 31 and 35 The cabinet frame of the feeder cabinet 300 is assembled by frame columns 111 and crossbeams 112 arranged between the frame columns 111 and first connecting members 400 and second connecting members 500, which can be made of aluminum, for example, for connecting them together. Here, these crossbeams 112 can be assembled in the form of Figures 21 to 25 , wherein the crossbeam 112 includes a slot 112A generally designed to be C-shaped and a first folded edge 112B or a second folded edge 112C connected thereto, wherein the first folded edge 112B for use with the first connector 400 described below has a wider width, for example, 100 mm, while the second folded edge 112C for use with the second connector 500 is narrower, for example, 50 mm.

[0134] Therefore, the improved feeder cabinet 300 (with dimensions of 500 mm in width and 2300 mm in height) not only ensures working performance but also meets the requirements of miniaturization, effectively overcoming the defects of the prior art.

[0135] Therefore, according to the low-voltage integrated power module of the present invention, on the one hand, the equipment width can be designed to be 500, 600, or 700 mm according to the functional requirements of the cabinet type, the depth is unified to 1050 mm, the height is unified to 2400 mm, and the effective utilization space of the equipment is unified to 1800 mm; on the other hand, the innovative incoming line connection cabinet architecture realizes the full-link copper bus prefabricated connection at the power module equipment level and system level, greatly improves the product's safety factor and installation operation efficiency, significantly shortens the deployment cycle, and can realize safe and efficient operation and maintenance of the product.

[0136] As another aspect of the present invention, the low-voltage converged power module can be used as a pure IT power module or as a shared power module for IT power, depending on the needs. The following describes feasible technical solutions for the low-voltage converged power module of the present invention, combining different power levels and functional requirements.

[0137] According to the capacity and load type of the power module, the present invention can be designed as an IT / power shared power module or a pure IT power module.

[0138] exist Figure 36 A pure IT power module with a capacity of, for example, 0.6 MW (megawatt) is shown in FIG. Figure 1-3 The low voltage fusion power module shown in Figure 36 The low voltage fusion power module shown in FIG has only a single UPS input / output cabinet 20A and a UPS cabinet 10A. Figure 36 From left to right, the following are included: low voltage incoming line / connection cabinet 100, reactive power compensation cabinet 200, maintenance bypass cabinet 30, UPS input / output cabinet 20A, UPS cabinet 10A (with Figure 4-5 The double-layer busbar room 1010 shown in FIG) and the first feeder cabinet 300A and the second feeder cabinet 300. The electrical components and related functions in each low-voltage switch cabinet are similar to those in FIG. Figure 1 The low voltage fusion power modules shown in are basically the same.

[0139] like Figure 36As shown, the incoming / interconnecting cabinet 100, reactive power compensation cabinet 200, maintenance bypass cabinet 30, UPS input / output cabinet 20A, UPS cabinet 10A, and first feeder cabinet 300A and second feeder cabinet 300 of the low-voltage integrated power module can be arranged sequentially from left to right; of course, it is also conceivable to arrange them sequentially from right to left. In addition to the single-row arrangement shown in the figure, it is also feasible to arrange them back to back.

[0140] Preferably, Figure 36 The low-voltage integrated power module can also include a power monitoring unit, wherein the power monitoring unit can be constructed to collect the operating parameters of any one of the incoming / connection cabinet 100, the reactive compensation cabinet 200, the maintenance bypass cabinet 30, the UPS input / output cabinet 20A, the UPS cabinet 10A and the first feeder cabinet 300A and the second feeder cabinet 300, and can obtain their operating status in real time to determine whether their operating status is normal. If an operating failure occurs, the switching timing of the switching elements therein (such as a frame-type circuit breaker, such as the model EZMX1-6300, which is a Cooper EZMX1 series air circuit breaker) can be controlled to ensure that the electrical equipment is supplied with normal power, thereby ensuring the normal operation and / or storage of data.

[0141] Specifically, the power monitoring unit can be constructed to detect the real-time operating parameters of each branch circuit and UPS in the low-voltage integrated power module. The distribution branch circuit monitoring parameters include but are not limited to: voltage, current, frequency, harmonics, electricity, power factor, active power, reactive power and UPS monitoring parameters include but are not limited to: input voltage, input current, output voltage, output current, bypass voltage, bypass current, input frequency, load rate, total operating time, battery backup time, battery voltage, battery current, and battery temperature.

[0142] Preferably, the power monitoring unit can also be constructed with local display and remote display functions, with a large color touch screen at the equipment site, which can collect data from the underlying equipment in a unified manner and conduct unified centralized monitoring and management. At the same time, it can remotely monitor, manage and display the power supply and distribution system through the network, such as Figure 36 shown.

[0143] Despite Figure 36 As shown in FIG, the power monitoring unit is shown as being built into the reactive power compensation cabinet 200. It is also conceivable that the power monitoring unit is built into the incoming cabinet 100 or the maintenance bypass cabinet 30.

[0144] exist Figure 37 Shown in Figure 36 The capacity of the different pure IT power modules can be, for example, 1.2MW (megawatt). Figure 36The low voltage fusion power module in Figure 37 The low voltage fusion power module shown in FIG has two UPS input / output cabinets 20A, 20B and UPS cabinets 10A, 10B. Figure 37 From left to right, the following are included: low voltage incoming line / connection cabinet 100, reactive power compensation cabinet 200, maintenance bypass cabinet 30, first UPS input / output cabinet 20A, first UPS cabinet 10A, second UPS input / output cabinet 20B, second UPS cabinet 10B (with Figure 4-5 The double-layer busbar room 1010 shown in FIG) and the first feeder cabinet 300A and the second feeder cabinet 300.
