The busbar coupling cabinet is equipped with circuit breakers or load switches to switch or distribute power between different busbars.

[0003] However, the traditional busbar cabinet needs to house larger busbars and connection components, and because the busbar needs to carry larger currents, its size and configuration must meet safety standards, which leads to an increase in the space required for the busbar cabinet. In addition to the large space occupied, the layout of the copper busbar also causes the problem of "wasteful busbars". Utility Model Content

[0004] The purpose of the present disclosure is to provide a connection assembly for a bus coupling cabinet and a bus coupling cabinet, so as to at least partially solve the above-mentioned problems and / or other potential problems existing in traditional bus coupling cabinets.

Thus, the path length of power transmission can be reduced, thereby saving copper busbar materials and costs. In addition, the plurality of second vertical rows are overlapped and distributed in the depth direction and the width direction, respectively, so that the internal space of the transfer cabinet can be fully utilized, making the layout of the connection assembly more compact and orderly to avoid space waste.

[0024] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure.

The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0026] As briefly mentioned above, traditional busbars have the problem of large space occupation and wasteful wiring. Specifically, for current levels of 4000A and below, the copper busbars (i.e., main conductors) in traditional busbars are arranged in a straight line, which increases the space required for arranging the copper busbars, thereby increasing the width and volume of the busbars, and making the connection paths between the copper busbars longer, resulting in wasteful wiring. The wasteful wiring problem of traditional busbars involves manufacturing and maintenance costs. When the copper busbars are longer or have a larger cross-section, the cost will also increase. In addition, traditional busbars for currents of 4000A and below do not adopt the layout of independent busbars.

[0027] In order to solve or at least partially solve the above-mentioned problems or other potential problems of the busbar cabinet of the traditional solution, an embodiment of the present disclosure provides a connection component for a busbar cabinet and a busbar cabinet solution. According to the solution of the embodiment of the present disclosure, the connection component includes a plurality of input rows, a plurality of first vertical rows, a plurality of connection rows, a plurality of output rows and a plurality of second vertical rows. Specifically, the plurality of input rows include at least one pair of first input rows and a pair of second input rows. At least one pair of first input rows is arranged along the depth direction of the busbar cabinet. The second input row is located below the first input row, so that the width of the switch cabinet can be reduced by utilizing the overlapping arrangement in the height direction, and the volume of the busbar cabinet can be reduced.

[0028] The first vertical row is coupled to a plurality of input rows, and the first vertical row extends along the height direction of the busbar cabinet and is arranged between a pair of first input rows and a second input row in the width direction, thereby providing a vertical current distribution path and ensuring that the power of each input row can be effectively managed and guided.

[0029] The plurality of connection rows are coupled to the first vertical row through a switch assembly. The switch assembly allows the connection and disconnection between the connection row and the first vertical row, so that the power can be turned on or off according to actual needs, thereby providing a flexible power management point to ensure the safety and efficiency of power distribution.

[0030] The plurality of output rows include at least one pair of first output rows and at least one pair of second output rows. The at least one pair of first output rows are arranged along the depth direction and adjacent to the at least one pair of first input rows, while the at least one pair of second output rows are placed below the first output rows, so that the width of the transfer cabinet can be reduced by overlapping the arrangement along the height direction, and the volume of the busbar cabinet can be reduced. The second vertical row extends along the height direction and is coupled to the plurality of output rows and the connection rows. Therefore, these output rows provide an orderly path for the power to flow from the busbar cabinet to the external device or circuit, ensuring that the power from the source input to the final output is effectively and safely processed in the busbar cabinet.

[0031] The following will be combined Figures 1 to 6 To describe an example structure of a busbar cabinet 100. In an embodiment of the present disclosure, a busbar cabinet 100 is provided. The busbar cabinet 100 includes a switch cabinet 110, a transfer cabinet 120, a connection assembly 130, and a switch assembly 111 such as a circuit breaker or a load switch, which work together to achieve efficient operation of power distribution and control.

[0032] Specifically, the switch cabinet 110 is used to arrange multiple input rows 131 and multiple first vertical rows 1303 of the connection assembly 130. The switch cabinet 110 includes switch assemblies 111, which are coupled between the first vertical row 1303 of the connection assembly 130 and multiple connection rows 1304, allowing effective control of the conduction and disconnection of the mother coupling cabinet 100, and realizing power flow management and protection through circuit breakers or load switches. When the power demand changes or a fault occurs, the switch assembly 111 can respond quickly and cut off the power supply, thereby ensuring the safety of the power system.

[0033] Furthermore, the transfer cabinet 120 is responsible for carrying multiple output rows 132 and multiple second vertical rows 1307 of the connection assembly 130. The transfer cabinet 120 is arranged adjacent to the switch cabinet 110, so that a close electrical connection can be achieved. The multiple second vertical rows 1307 are connected to the first vertical row 1303 through multiple connection rows 1304 and with the help of the switch assembly 111, ensuring that power flows from the switch cabinet 110 to the transfer cabinet 120.

[0034] Therefore, the switch cabinet 110 realizes the introduction of power and distributes it to the transfer cabinet 120 through the connection component 130. At the same time, the transfer cabinet 120 ensures that power can be safely and effectively output from the inside of the switch cabinet 110 to the external power-consuming equipment or system through the connection component 130. In addition, the busbar cabinet 100 in the embodiment of the present disclosure can be laid out using an independent busbar cabinet 100.

[0035] The following will mainly describe the concept of the present disclosure with respect to the case of the connection component 130. It should be understood that the case of other application connection components 130 is similar and will not be described separately in the following. For ease of description, the connection component 130 used for the mother coupling cabinet 100 in the embodiment of the present disclosure will be further described below.

[0036] like Figures 1 to 6 As shown, the connection assembly 130 for the mother coupling cabinet 100 according to the embodiment of the present disclosure generally includes a plurality of input rows 131 , a plurality of first vertical rows 1303 , a plurality of connection rows 1304 , a plurality of output rows 132 and a plurality of second vertical rows 1307 .

[0037] Specifically, the plurality of input rows 131 include at least one pair of first input rows 1301 and at least one pair of second input rows 1302. They are arranged overlappingly along the height direction C and the depth direction A (separated by a predetermined distance, also referred to as a herringbone arrangement) to improve the power receiving capacity and flexibility of the motherboard 100.

[0038] like Figure 5 and Figure 6 As shown, additionally or alternatively, at least one pair of first input rows 1301 and at least one pair of second input terminals are arranged in the depth direction A with two pairs of first input rows 1301 and two pairs of second input rows 1302 .

[0039] Further, at least one pair of first input rows 1301 extends along the width direction B of the bus coupling cabinet 100, and is arranged along the depth direction A of the bus coupling cabinet 100. At the same time, at least one pair of second input rows 1302 is arranged below at least one pair of first input rows 1301, and their positions correspond to the first input rows 1301, maintaining the continuity and symmetry of the overall structure, so as to allow currents of different phases (for example, N phase, A phase, B phase and C phase) to enter the switch 110 respectively, and can cooperate well with other structural components inside the bus coupling cabinet 100 to realize power distribution and management.

[0040] This hierarchical arrangement can not only optimize space utilization, but also enable each input row 131 to connect to a specific power source or voltage level, thereby making the power input management of the busbar 100 more efficient. In addition, the first input row 1301 and the second input row 1302 can be connected to different power sources, or adapt to specific voltage requirements, so as to allow the busbar 100 to access multiple power sources at the same time, thereby increasing the redundancy and stability of the power system to adapt to various load conditions and grid changes.

[0041] Continuing to describe the first vertical row 1303, a plurality of first vertical rows 1303 are respectively coupled to a plurality of input rows 131 to meet the requirements of power distribution. These first vertical rows 1303 extend along the height direction C of the bus coupling cabinet 100, and can make full use of the vertical space of the bus coupling cabinet 100 to provide a vertical current distribution path. In the width direction B of the bus coupling cabinet 100, these first vertical rows 1303 are arranged between a pair of first input rows 1301 and a pair of second input rows 1302. Such an arrangement order (i.e., a straight-line arrangement) enables them to provide a uniform and orderly power source for each branch inside the bus coupling cabinet 100.

[0042] Through this arrangement, the motherboard 100 can provide a larger current distribution capacity in a limited space. Each first vertical row 1303 is connected to the corresponding input row 131, which can directly transmit the power introduced by these input rows 131, and then distribute the current to the corresponding connection row 1304 as needed. Therefore, the high-capacity current entering from the input row is distributed by the first vertical row 1303 and then distributed to each required terminal with a lower capacity.

[0043] Continuing to describe the connection row 1304, in order to achieve efficient power distribution and management, multiple connection rows 1304 are coupled to multiple first vertical rows 1303 through the switch assembly 111. This configuration utilizes the on and off functions of the switch assembly 111 to ensure that the current between the connection row 1304 and the first vertical row 1303 can be effectively controlled and managed. Each connection row 1304 is connected to the first vertical row 1303 through the switch assembly 111, and the current can be turned on or off according to demand at different times, thereby flexibly allocating power.

[0044] When a circuit needs to be disconnected from the power supply, the corresponding switch assembly 111 only needs to be operated to be in the disconnected state, and the current between the corresponding connection row 1304 and the first vertical row 1303 will be effectively isolated. Conversely, when the current channel needs to be opened, the connection row 1304 is connected to the first vertical row 1303 by operating the conduction function of the switch assembly 111 to realize the transmission of current.

[0045] The coupling mode achieved by the switch assembly 111 makes power management more accurate and efficient. The switch assembly 111 not only ensures the stability and safety of the current, but also makes maintenance work more convenient. If a part of the circuit needs to be repaired, it is only necessary to disconnect the relevant switch assembly 111 to perform safe operation without affecting the normal operation of other parts. Therefore, not only the reliability of the entire system is improved, but also great convenience is provided for the operation and maintenance of the mother coupling cabinet 100.

[0046] Continuing to describe the output row 132 , in order to ensure that electricity can be efficiently distributed to various power consumption points, the multiple output rows 132 inside the switching cabinet 120 of the main coupling cabinet 100 are arranged in a hierarchical manner along the depth direction A and the height direction C.

[0047] Specifically, the plurality of output rows 132 include at least one pair of first output rows 1305 and at least one pair of second output rows 1306. They extend along the width direction B of the busbar cabinet 100 and are arranged along the depth direction A of the busbar cabinet 100. At the same time, at least one pair of first input rows 1301 is spatially adjacent. In addition, at least one pair of second output rows 1306 is located below the first output row 1305. The arrangement position of the output row 132 makes the current distribution of the busbar cabinet 100 have a hierarchical structure, which is convenient for orderly power supply to loads of different levels or types. Through such vertical stacking and optimized layout (i.e., the herringbone layout), the copper busbar path can be significantly saved, thereby reducing costs. In addition, this layout method also effectively reduces the cabinet width, thereby facilitating the compact layout of the busbar cabinet.

[0048] like Figure 5 and Figure 6 As shown, additionally or alternatively, at least one pair of first output rows 1305 and at least one pair of second output terminals are arranged in the depth direction A with two pairs of first output rows 1305 and two pairs of second output rows 1306 .

[0049] Continuing to describe the second vertical rows 1307 , the plurality of second vertical rows 1307 extend along the height direction C, effectively utilizing the vertical space of the busbar cabinet 100 .

[0050] Each second vertical row 1307 is coupled with a plurality of output rows 132 and a plurality of connection rows 1304, respectively, to form an efficient electrical connection, ensuring that electricity can be distributed to each required output row 132 after precise control from the input row 131. Through such a configuration, each second vertical row 1307 can not only guide electricity from the input row 131 to the corresponding connection row 1304, but also ensure that electricity is smoothly transmitted to the required output row 132. This not only increases the accuracy and controllability of power distribution, but also greatly improves the safety and reliability of the system. Through the vertical stacking and optimized layout (i.e., the herringbone layout) of the output rows 132, the second vertical rows 1307 also realize a layered layout in the depth direction A and the width direction B of the main coupling cabinet 100, thereby realizing the transfer in the transfer cabinet 120 of limited space size.

[0051] Therefore, the busbar cabinet 100 in the embodiment of the present disclosure can reduce the path length of power transmission through the hierarchical layout and coupling mode of the output row 132 and the second vertical row 1307, thereby saving copper bar materials and costs. At the same time, it is possible to reduce the width of the transfer cabinet 120, reduce the volume of the busbar cabinet 100, and ensure that the busbar cabinet 100 can meet the power requirements in various complex scenarios. For example, the busbar cabinet 100 in the embodiment of the present disclosure can be suitable for a transfer cabinet 120 with a width of 350 mm to meet the power requirements in installation scenarios with limited space.

[0052] like Figures 1 to 6 As shown, in some embodiments, a plurality of second vertical rows 1307 are arranged on the same side of the first output row 1305 and the second output row 1306. For example, the B phase and the C phase corresponding to the second vertical row 1307 are arranged on the side of the first output row 1305 and the second output row 1306 close to the switch assembly 111. The N phase and the A phase corresponding to the second vertical row 1307 are arranged on the side of another first output row 1305 and another second output row 1306 close to the switch assembly 111.

[0053] Specifically, by arranging the second vertical row 1307 on the same side as the output row 132, the distribution path of power from input to output can be greatly simplified. In this way, the path through which power passes is shorter, which means that the loss of power during transmission can be reduced, and the efficiency and stability of the entire system can be improved. Secondly, such a layout helps to reduce the length and number of connected busbars, thereby reducing the use and cost of copper busbars.

[0054] In addition, this layout enables the transfer cabinet 120 and the switch cabinet 110 of the busbar cabinet 100 to achieve more efficient power distribution in a limited space. It can not only improve the performance and reliability of the power system, but also ensure that the appearance of the power distribution facilities is more compact, which is convenient for integration in various environments, whether it is a space-constrained indoor environment or an industrial application that requires dense layout.

[0055] In some embodiments, the plurality of second vertical rows 1307 are spaced apart by a predetermined distance in the width direction B of the busbar cabinet 100 and are coupled with the output row 132, so that the space configuration inside the transfer cabinet 120 can be optimized. By setting a suitable spacing distance, it can be ensured that there is sufficient electrical clearance between each second vertical row 1307 to ensure the safety of the power system.

[0056] In some embodiments, the first output row 1305 and the second output row 1306 have the same length in the width direction B, thereby ensuring that the two groups of output rows 132 have the same length in the width direction B, and achieving symmetry and balance of the power system structure. This symmetrical layout helps to simplify the installation process and wiring work of the power distribution system.

[0057] Furthermore, the same length of the output row 132 can ensure the equivalent length of the power transmission path, thereby achieving balanced power distribution. Balanced power distribution can not only reduce power loss on the line, but also ensure that each output point obtains a stable power supply, preventing some parts from being affected by uneven voltage or current, thereby ensuring the overall performance and reliability of the power system.

[0058] In some embodiments, the plurality of second vertical rows 1307 are coupled to the cabinet 101 of the busbar cabinet 100 through insulating connectors 1310, so that the plurality of second vertical rows 1307 can be reliably arranged on the cabinet 101 while ensuring the safety of electrical connection.

[0059] Specifically, the insulating connector 1310 can effectively isolate the vertical row and the cabinet 101, avoid possible electrical short circuit or leakage, and protect the stable operation of the power system and the safety of operators. The insulating connector 1310 is usually made of high-strength, high-temperature resistant insulating materials, which can withstand electrical loads and adapt to various environmental conditions to ensure long-term stable operation.

[0060] Furthermore, the second vertical row 1307 is coupled to the cabinet 101 of the busbar cabinet 100 through the insulating connector 1310, which can provide a stable and reliable fixing method. This fixing method can not only keep the second vertical row 1307 in a proper position in the cabinet, reducing the risk of displacement due to vibration or external forces, but also facilitate subsequent maintenance and adjustment.

[0061] In some embodiments, the connection assembly 130 includes a plurality of brackets 1308 coupled to the cabinet body 101 of the busbar cabinet 100. A plurality of input rows 131 and a plurality of output rows 132 are coupled to the brackets 1308.

[0062] Specifically, the brackets 1308 can be made of strong insulating materials, such as high-performance plastics, which are capable of holding the input and output rows 131, 132 in place and capable of withstanding the weight from heavy cables and equipment.

[0063] Further, the bracket 1308 can be configured to accommodate different sizes and types of input rows 131 and output rows 132 to achieve tight and orderly coupling. In this way, the bracket 1308 helps achieve precise alignment of the cable and the external device, ensuring stable current transmission, thereby reducing the electrical impedance of the connection.

[0064] In some embodiments, in order to ensure the overall efficiency and safety of the circuit, the plurality of input rows 131 and the plurality of output rows 132 are aligned in the width direction B. In this way, the orderliness of the cable wiring can be ensured, thereby achieving a clear and systematic wiring path.

[0065] In some embodiments, the connection assembly 130 further includes a T-shaped connector 1309 for coupling the plurality of input rows 131 and the plurality of output rows 132 to the first vertical row 1303 and the second vertical row 1307 , respectively.

[0066] Through the T-shaped connector 1309, the input row 131 and the output row 132 can be precisely aligned and fixed with the vertical row in the vertical direction. This coupling method can not only ensure the stable transmission of electrical signals, but also reduce the resistance and energy loss at the connection. The vertical row can effectively connect and manage each input row 131 and output row 132 through the T-shaped connector 1309, thereby optimizing the wiring structure of the entire system and making power distribution more efficient.

[0067] In some embodiments, a pair of bends are formed at the ends of the connection row 1304, which are respectively coupled to the first vertical row 1303 and the second vertical row 1307, which not only enhances the stability of the connection but also improves the electrical performance and safety of the entire system.

[0068] Furthermore, the bends can establish a more compact and firm connection between the connecting row 1304 and the vertical row. At the same time, the bends can be directly coupled to the first vertical row 1303 and the second vertical row 1307, making the layout of the connecting row 1304 more intuitive and orderly, and facilitating the inspection and maintenance of the power system.

[0069] The above descriptions of various implementations of the present disclosure are exemplary, non-exhaustive, and not limited to the disclosed implementations. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described implementations. The selection of terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the various implementations disclosed herein.
