Description

Technical Field

[0001] This invention relates to the field of energy storage system technology, and more specifically, to a boost converter component and an integrated energy storage converter boost converter. Background Technology

[0002] In related technologies, the boost converter components of energy storage converter integrated units have always followed the traditional structural scheme of independent low-voltage distribution cabinets entering the cabin. That is, the electrical components of the low-voltage distribution cabinet are assembled and the cabinet is manufactured offline first, and then the whole unit is placed into the low-voltage distribution room that is pre-isolated in the boost converter components. This nested cabinet-within-a-cabinet structure design results in the cabin wall of the low-voltage distribution room and the cabinet wall of the distribution cabinet being double-overlapped, directly causing waste of sheet metal materials. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the first aspect of the present invention proposes a boost converter assembly.

[0006] In view of this, a first aspect of the present invention provides a step-up converter assembly, which includes a housing, a partition, a door panel, and low-voltage power distribution components.

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0044] The following is combined with Figures 1 to 18 This invention describes a boost converter assembly and an integrated energy storage converter boost converter proposed in this invention.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, a step-up converter assembly is proposed, which includes a housing 110, a partition 120, a door panel 150, and a low-voltage power distribution component 170. The housing 110 includes a bottom plate 112, a top plate 114 disposed opposite to the bottom plate 112, and a front plate 116 connected between the bottom plate 112 and the top plate 114; the partition 120 is disposed inside the housing 110 and divides the interior of the housing 110 to form a low-voltage power distribution chamber 140; the front plate 116 has an operation opening 118 corresponding to the position of the low-voltage power distribution chamber 140, and the door panel 150 is rotatably connected to the front plate 116 and can be opened and closed to cover the operation opening 118; the partition 120, the bottom plate 112, the top plate 114, and the door panel 150 together define an installation space 160; the low-voltage power distribution component 170 is located in the installation space 160 and is connected to the surface of the partition 120 facing the installation space 160.

[0046] In this embodiment, the cabin 110 serves as the external load-bearing enclosure structure for the boost converter assembly. The bottom plate 112 is a horizontally arranged bottom load-bearing plate, and the top plate 114 is a horizontally arranged top sealing plate. The top plate 114 and the bottom plate 112 are arranged parallel to each other vertically along the height direction of the cabin 110. A partition 120 is installed inside the cabin 110, dividing the cabin 110 into a low-voltage power distribution room 140. The low-voltage power distribution room 140 is a compartment inside the cabin 110 used to house low-voltage power distribution equipment. A door panel 150 is installed at the opening of the low-voltage power distribution room 140 facing the outside of the cabin 110, and can rotate around a hinge axis to open and close the opening of the low-voltage power distribution room 140.

[0047] The side surface of the partition 120 facing the interior of the low-voltage distribution room 140, the upper surface of the bottom plate 112 of the cabin 110, the lower surface of the top plate 114 of the cabin 110, and the inner surface of the door panel 150 together form a closed installation space 160, which is the installation area for the low-voltage power distribution component 170. The low-voltage power distribution component 170 is installed inside the installation space 160, and the back of the low-voltage power distribution component 170 is connected to the surface of the partition 120 facing the installation space 160. There is no additional independent cabinet structure between the low-voltage power distribution component 170 and the partition 120.

[0048] In related technologies, the step-up converter assembly adopts a structure where an independent low-voltage distribution cabinet is installed within the compartment. After the entire cabinet is commissioned, the entire low-voltage distribution cabinet is hoisted into the pre-isolated low-voltage distribution room inside the step-up converter assembly using hoisting equipment, and then connected to the bottom plate of the compartment via supports at the bottom of the cabinet. This technology is a typical cabinet-within-a-cabinet nested structure, where the walls of the low-voltage distribution room and the cabinet of the low-voltage distribution cabinet form two independent sheet metal walls. A hoisting gap and a heat dissipation gap are reserved between the two walls, directly resulting in a waste of sheet metal materials.

[0049] This invention addresses the shortcomings of related technologies by structurally improving upon existing designs. It eliminates the need for a separate low-voltage distribution cabinet, directly utilizing the inherent enclosure structure of the low-voltage distribution room 140 as the mounting carrier for the low-voltage distribution component 170. The low-voltage distribution component 170 is directly mounted on the surface of the partition 120 separating the low-voltage distribution room 140, eliminating the need for additional fabrication and assembly of a separate distribution cabinet, or the need to hoist the entire distribution cabinet into the compartment. Compared to related technologies, this invention eliminates the entire sheet metal structure of the independent distribution cabinet, removes the double overlap between the compartment wall 110 and the distribution cabinet wall, and eliminates the reserved gap between the two walls, thus eliminating material waste caused by double walls and directly reducing the material cost of the equipment.

[0050] Furthermore, in related technologies, the functional compartments within the step-up converter assembly are already isolated from each other by partitions. The additional fabrication of a separate distribution cabinet within the functional compartment adds numerous components such as cabinet frames, doors, locks, mounting beams, and mounting supports, increasing the system's structural complexity. The internal space of the low-voltage distribution room must be larger than the overall volume of the low-voltage distribution cabinet, resulting in a waste of internal space. A separate distribution cabinet requires four independent processes: cabinet fabrication, component assembly, overall cabinet commissioning, and overall installation in the cabin, consuming additional manpower and resources.

[0051] The structure proposed in this invention directly utilizes the inherent partition 120 of the low-voltage distribution room 140 as the mounting carrier, eliminating the need for additional independent distribution cabinet construction and reducing the structural complexity of the system. The low-voltage distribution components 170 are directly mounted on the surface of the partition 120, eliminating the need for pre-reserved hoisting and installation clearances for the distribution cabinet. The entire internal space of the low-voltage distribution room 140 can be used for device installation and operation, improving the space utilization rate of the low-voltage distribution room 140. This invention eliminates the need for independent distribution cabinet construction, separate assembly, overall cabinet debugging, and overall hoisting processes, reducing the consumption of manpower and resources.

[0052] Optionally, the cabin 110 also includes side panels, one end of which is connected to the bottom plate 112, and the other end of which is connected to the top plate 114, forming a complete cabin 110 structure. The side panels are vertically arranged around the perimeter of the bottom plate 112. Together with the bottom plate 112 and the top plate 114, the side panels form a rectangular closed cabin 110 shell, providing external protection for the equipment inside the cabin 110 and blocking dust, rainwater, and external impacts.

[0053] Optionally, the partition 120 can be a one-piece partition, which is U-shaped. The one-piece partition is formed from a single piece of sheet metal through a bending process. The middle section of the one-piece partition is a horizontal plate, and the two side sections are vertical plates, with the side sections perpendicular to the middle section. The one-piece partition is installed inside the compartment 110, partitioning the internal space and directly enclosing the three-sided enclosure structure of the low-voltage power distribution room 140. The one-piece partition has high overall structural strength, fewer installation steps, and high assembly efficiency.

[0054] Optionally, the partition 120 can also be multiple separate panels, each positioned within the compartment 110. The ends of the multiple separate panels are connected to each other, forming a low-voltage power distribution compartment 140. The separate panels are easy to manufacture, and their length and installation position can be flexibly adjusted according to the size requirements of different compartments, adapting to different aircraft models.

[0055] Optionally, the low-voltage distribution room 140 is an independent compartment inside the cabin 110 for installing low-voltage power distribution equipment. The low-voltage distribution room 140 is separated from other functional rooms inside the cabin 110 by a partition 120, so as to achieve physical isolation between low-voltage electrical equipment and high-voltage equipment and transformer equipment, and ensure the safety of equipment operation and personnel operation.

[0056] Optionally, the low-voltage power distribution component 170 is an electrical device used in a low-voltage power distribution circuit to realize the functions of low-voltage power distribution, control, monitoring, protection and signal transmission.

[0057] Optionally, the surface of the partition 120 facing the installation space 160 is the side surface of the partition 120 facing the interior of the low-voltage distribution room 140. This surface is the mounting reference surface of the low-voltage distribution component 170, and the surface flatness meets the installation accuracy requirements of the electrical components.

[0058] Optionally, the low-voltage power distribution component 170 is detachably connected to the surface of the partition 120 facing the installation space 160. The low-voltage power distribution component 170 and the partition 120 are connected by a detachable method such as bolts, allowing for individual removal and replacement of faulty components during later maintenance without dismantling the entire structure, thus improving maintenance convenience.

[0059] Optionally, the partition 120 is disposed inside the compartment 110. Specifically, the bottom edge of the partition 120 is connected to the upper surface of the bottom plate 112, the top edge of the partition 120 is connected to the lower surface of the top plate 114, and the side edges of the partition 120 are connected to the inner sidewall of the compartment 110 at the corresponding positions, so that the partition 120 forms a stable vertical partition structure inside the compartment 110, and the strength of the partition structure meets the protection requirements of compartment isolation.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, optionally, the partition 120 includes a first partition 122, a second partition 128, and a third partition 134, and the interior of the cabin 110 is further divided to form a high-voltage chamber 208, a main transformer chamber 212, and an auxiliary transformer chamber 210; the first partition 122 extends along the front-rear direction of the cabin 110 and separates the low-voltage distribution chamber 140 from the auxiliary transformer chamber 210; the second partition 128 extends along the left-right direction of the cabin 110 and separates the low-voltage distribution chamber 140 from the high-voltage chamber 208, the second partition 122... One end of the second partition 128 is connected to the rear end of the first partition 122, and the other end of the second partition 128 is connected to the rear end of the third partition 134. The third partition 134 extends along the front-rear direction of the cabin 110 and separates the low-voltage distribution room 140 from the main transformer room 212. The first partition 122 and the third partition 134 are arranged opposite each other along the left-right direction of the cabin 110. The low-voltage distribution component 170 is connected to at least one of the first partition 122, the second partition 128 and the third partition 134 on the surface facing the installation space 160.

[0061] In this embodiment, the partition 120 is composed of three independent plate structures: a second partition 128, a third partition 134, and a first partition 122. The second partition 128 is located along the left-right direction of the compartment 110 (e.g., ...). Figure 5 (as indicated by arrow A in the diagram) extends along the front-rear direction of the hull 110 (as shown by arrow A in the diagram). The third partition 134 and the first partition 122 both extend along the front-rear direction of the hull 110 (e.g., as shown by arrow A in the diagram). Figure 6(As indicated by arrow B in the diagram). The rear end of the third partition plate 134 is connected to the left end of the second partition plate 128, and the front end of the third partition plate 134 extends to the inner surface of the front sidewall of the cabin 110. The rear end of the first partition plate 122 is connected to the right end of the front surface of the second partition plate 128, and the front end of the first partition plate 122 extends to the inner surface of the front sidewall of the cabin 110. The second partition plate 128, the third partition plate 134, and the first partition plate 122 together form a U-shaped partition structure with the opening facing forward, simultaneously dividing the cabin 110 into four independent compartments: a low-voltage power distribution compartment 140, a high-voltage compartment 208, a main transformer compartment 212, and an auxiliary transformer compartment 210. The low-voltage power distribution compartment 140 is located in the inner region of the U-shaped structure, the high-voltage compartment 208 is located in the rear region of the second partition plate 128, the main transformer compartment 212 is located in the left region of the third partition plate 134, and the auxiliary transformer compartment 210 is located in the right region of the first partition plate 122.

[0062] This invention employs a three-piece modular structure, allowing for independent adjustment of the installation position and length of each piece to accommodate different compartment sizes and enhance the flexibility of compartment layout. The three pieces simultaneously serve the dual functions of compartment partitioning and component installation, eliminating the need for separate mounting cabinets and achieving multi-functionality.

[0063] In this embodiment, the high-voltage chamber 208 is a chamber inside the cabin 110 used to install high-voltage power distribution equipment. The high-voltage chamber 208 is located on the side of the second partition 128 away from the low-voltage power distribution chamber 140. The high-voltage chamber 208 and the low-voltage power distribution chamber 140 are physically isolated by the second partition 128.

[0064] In this embodiment, the main transformer compartment 212 is the compartment inside the body 110 used to install the main transformer. The main transformer compartment 212 is located on the side of the third partition 134 away from the low-voltage distribution room 140. The main transformer compartment 212 and the low-voltage distribution room 140 are physically isolated by the third partition 134.

[0065] In this embodiment, the auxiliary transformer room 210 is a compartment inside the body 110 used to install an auxiliary transformer. The auxiliary transformer room 210 is located on the side of the first partition plate 122 away from the low-voltage power distribution room 140. The auxiliary transformer room 210 and the low-voltage power distribution room 140 are physically isolated by the first partition plate 122.

[0066] Optionally, the second partition plate 128, the third partition plate 134 and the first partition plate 122 are connected by welding. The connection position is a full weld structure. The structural strength of the connection position meets the protection requirements of the compartment separation, while ensuring the electrical protection performance of the connection position.

[0067] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of the present invention, optionally, a first air intake grille 152 is provided in the area of ​​the door panel 150 corresponding to the low-voltage power distribution room 140, and the low-voltage power distribution room 140 is connected to the outside of the cabin 110 through the first air intake grille 152; the first air intake grille 152 is arranged close to the bottom plate 112 along the direction from the bottom plate 112 to the top plate 114.

[0068] In this embodiment, the first air intake grille 152 is directly formed on the door panel 150 of the cabin 110, serving as an independent air intake channel for the low-voltage power distribution room 140. Outside cold air can directly enter the low-voltage power distribution room 140 through the first air intake grille 152. By eliminating the independent power distribution cabinet, there is no need to separately form an air intake grille on the cabinet door; the door panel 150 of the cabin 110 is used directly as the air intake carrier, reducing redundant openings and associated dustproof structures, and simplifying the overall structure.

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of the present invention, optionally, along the direction from the bottom plate 112 to the top plate 114, the height of the first partition plate 122 is less than the height of the installation space 160, so that a first gap 198 is formed between the top of the first partition plate 122 and the top plate 114; the low-voltage distribution room 140 is connected to the auxiliary transformer room 210 through the first gap 198.

[0070] In this embodiment, the height of the installation space 160 is the vertical distance from the upper surface of the bottom plate 112 to the lower surface of the top plate 114, and the height of the first partition plate 122 is the vertical distance from the bottom edge to the top edge of the first partition plate 122. The vertical height of the first partition plate 122 is less than the vertical height of the installation space 160. The bottom edge of the first partition plate 122 is connected to the upper surface of the bottom plate 112, and the top edge does not contact the lower surface of the top plate 114. A transversely penetrating gap is left between the top edge of the first partition plate 122 and the lower surface of the top plate 114; this gap is the first gap 198. The first gap 198 extends from the front end of the first partition plate 122 to the rear end of the first partition plate 122 along the front-rear direction of the cabin 110, and the cross-section of the first gap 198 along the left-right direction of the cabin 110 is rectangular. The top space of the low-voltage distribution room 140 is connected to the top space of the auxiliary transformer room 210 through the first gap 198, and the air inside the low-voltage distribution room 140 can freely flow into the auxiliary transformer room 210 through the first gap 198.

[0071] This invention eliminates the need for a separate distribution cabinet design. It avoids the need for standard protection level certification and mechanical strength verification for separate distribution cabinets, as well as separate seismic simulation calculations and the design of separate heat dissipation ducts and selection of heat dissipation devices. By reducing the height of the first partition plate 122, the low-voltage distribution room 140 and the auxiliary transformer room 210 are connected in the top space. The heat dissipation ducts of the low-voltage distribution room 140 and the auxiliary transformer room 210 are shared, eliminating the need for a separate heat dissipation system for the low-voltage distribution room 140.

[0072] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of the present invention, optionally, the boost converter assembly further includes a heat dissipation component 206, which is disposed inside the auxiliary transformer chamber 210.

[0073] In this embodiment, the air inlet side of the heat dissipation component 206 faces the interior space of the auxiliary transformer chamber 210, and the air outlet side of the heat dissipation component 206 faces the exterior space of the cabin 110. When the heat dissipation component 206 is in operation, it can drive the airflow inside the auxiliary transformer chamber 210, exhausting the hot air inside the auxiliary transformer chamber 210 to the outside of the cabin 110.

[0074] This invention utilizes a top-connected structure between the low-voltage distribution room 140 and the auxiliary transformer room 210. By arranging only one set of heat dissipation components 206 within the auxiliary transformer room 210, the heat dissipation function of both the low-voltage distribution room 140 and the auxiliary transformer room 210 can be simultaneously achieved, allowing for the sharing of the heat dissipation component 206. When the heat dissipation component 206 is working, it draws air from inside the auxiliary transformer room 210, creating a negative pressure inside. Outside cold air enters the low-voltage distribution room 140 through the first air inlet grille 152 on the door panel 150. The cold air flows upwards across the surface of the low-voltage distribution component 170, absorbing the heat generated by the low-voltage distribution component 170 to form hot air. The hot air naturally rises to the top space of the low-voltage distribution room 140 and flows into the top space of the auxiliary transformer room 210 through the first gap 198. After the hot air merges with the hot air generated by the auxiliary transformer in the auxiliary transformer compartment 210, it is drawn in by the heat dissipation component 206 and discharged outside the compartment 110, completing the heat dissipation cycle of the two compartments.

[0075] In some embodiments of the present invention, optionally, the heat dissipation component 206 is positioned corresponding to the first gap 198, and the air inlet range of the heat dissipation component 206 covers the air outlet range of the first gap 198.

[0076] In this embodiment, the installation position of the heat dissipation component 206 in the auxiliary transformer compartment 210 is aligned with the position of the first gap 198 in the left-right direction of the cabin 110. The air intake coverage of the heat dissipation component 206 completely covers the air outlet coverage of the first gap 198.

[0077] The present invention, through a corresponding layout, allows hot air flowing out of the low-voltage distribution room 140 through the first gap 198 to directly enter the air intake range of the heat dissipation component 206, reducing the diffusion and retention of hot air inside the auxiliary transformer room 210, shortening the flow path of hot air, improving the overall heat dissipation efficiency, and preventing hot air from accumulating inside the auxiliary transformer room 210, which would cause the operating temperature of the auxiliary transformer to rise.

[0078] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in some embodiments of the present invention, optionally, a second air intake grille 200 is provided in the area of ​​the front panel 116 corresponding to the auxiliary transformer room 210, and the auxiliary transformer room 210 is connected to the outside of the cabin 110 through the second air intake grille 200; a connecting plate 202 is provided between the first partition plate 122 and the front panel 116 on one side edge near the front panel 116, one end of the connecting plate 202 is connected to the first partition plate 122, and the other end of the connecting plate 202 is connected to the front panel 116; at least one ventilation hole 204 is provided on the connecting plate 202, and the low-voltage power distribution room 140 is connected to the auxiliary transformer room 210 through the ventilation hole 204.

[0079] In this embodiment, the present invention provides an air intake structure for the auxiliary transformer side. A second air intake grille 200 is provided on the front panel 116 corresponding to the area of ​​the auxiliary transformer chamber 210. The auxiliary transformer chamber 210 is connected to the outside of the cabin 110 through the second air intake grille 200. Cold air from the outside can enter the interior of the auxiliary transformer chamber 210 from the outside of the cabin 110 through the second air intake grille 200, providing a fresh air source for the heat dissipation process.

[0080] Furthermore, the present invention also includes a connecting plate 202. A connecting plate 202 is provided between the first partition plate 122 and the front plate 116 on one side edge near the front plate 116. One end of the connecting plate 202 is connected to the first partition plate 122, and the other end of the connecting plate 202 is connected to the front plate 116. At least one ventilation hole 204 is provided on the connecting plate 202. The low-voltage distribution room 140 is connected to the auxiliary transformer room 210 through the ventilation hole 204. Air in the auxiliary transformer room 210 can enter the low-voltage distribution room 140 through the ventilation hole 204, forming an auxiliary airflow channel between the two chambers on the front side.

[0081] Figure 11 The middle arrow illustrates the airflow process. When the heat dissipation component 206 is working, it draws air outward, creating a negative pressure inside the auxiliary transformer chamber 210. External cold air enters the auxiliary transformer chamber 210 through the second air inlet grille 200. The air entering the auxiliary transformer chamber 210 is divided into two parts. One part flows directly inside the auxiliary transformer chamber 210, carrying away the heat from the components inside. The other part enters the low-voltage distribution chamber 140 through the ventilation holes 204 on the connecting plate 202, cooling the components inside the low-voltage distribution chamber 140. It then flows upward within the low-voltage distribution chamber 140, and then flows back to the auxiliary transformer chamber 210 through the first gap 198 at the top, finally carrying the heat and being discharged outside the chamber through the heat dissipation component 206.

[0082] Through the above structural design, the present invention supplements the airflow channel of the ventilation hole 204 of the connecting plate 202 on the front side, and together with the first gap 198 at the top, forms a complete airflow circulation path from bottom to top within the low-voltage power distribution room 140, avoiding airflow dead zones within the low-voltage power distribution room 140 and improving the heat dissipation uniformity inside the low-voltage power distribution room 140. Meanwhile, the second air inlet grille 200 is separately installed in the auxiliary transformer room 210, with a short air inlet path and low air inlet resistance.

[0083] Optionally, the number of ventilation holes 204 on the connecting plate 202 can be set to multiple, and the multiple ventilation holes 204 are arranged at intervals along the direction from the bottom plate 112 to the top plate 114, so that the air intake can cover areas at different heights of the low-voltage power distribution room 140.

[0084] In some embodiments of the present invention, optionally, the cabin 110 further includes a side plate, the side plate and the first partition plate 122 are arranged opposite to each other in the left and right direction of the cabin 110, and the side plate, the first partition plate 122, the bottom plate 112 and the top plate 114 together form the auxiliary transformer chamber 210; the heat dissipation component 206 includes a heat dissipation fan, the heat dissipation fan is disposed on the side plate, the air inlet of the heat dissipation fan faces the interior of the auxiliary transformer chamber 210, and the air outlet of the heat dissipation fan faces the exterior of the cabin 110; along the direction from the bottom plate 112 to the top plate 114, the distance between the heat dissipation fan and the top plate 114 is less than the distance between the heat dissipation fan and the bottom plate 112.

[0085] In this embodiment, the present invention specifies the specific form of the side plate and the heat dissipation component 206 of the cabin 110. The cabin 110 also includes a side plate, which is arranged opposite to the first partition plate 122 in the left-right direction of the cabin 110. The side plate, the first partition plate 122, the bottom plate 112, and the top plate 114 together form the auxiliary transformer chamber 210. The side plate serves as the side wall of the auxiliary transformer chamber 210, providing an installation carrier for the heat dissipation component 206, and simultaneously enclosing the lateral boundary of the auxiliary transformer chamber 210.

[0086] The heat dissipation component 206 includes a heat dissipation fan, which is disposed on the side plate. The air inlet of the heat dissipation fan faces the interior of the auxiliary transformer compartment 210, and the air outlet of the heat dissipation fan faces the exterior of the compartment 110. Along the direction from the bottom plate 112 to the top plate 114, the distance between the heat dissipation fan and the top plate 114 is less than the distance between the heat dissipation fan and the bottom plate 112. The heat dissipation fan is arranged in the upper region of the side plate, close to the top plate 114.

[0087] During operation, the cooling fan starts, drawing in hot air from the auxiliary transformer chamber 210 through the air inlet and then discharging the hot air to the outside of the cabin 110 through the air outlet. Because the cooling fan is located close to the top plate 114, it takes advantage of the upward gathering characteristic of hot air and can directly draw away the hot air gathered at the top of the auxiliary transformer chamber 210, preventing heat from accumulating at the top of the cabin 110.

[0088] The cooling fan is mounted on the side panel, which simplifies the installation structure. During maintenance, the fan can be directly removed and installed from the outside of the compartment 110 without entering the auxiliary transformer room 210. The upper placement of the fan takes full advantage of the natural law of hot air rising, improving exhaust efficiency, while freeing up space under the side panel and not affecting the arrangement of components inside the auxiliary transformer room 210.

[0089] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments of the present invention, optionally, the low-voltage power distribution component 170 includes a backup power component 172, a power switching switch 174, a first communication component 176, and a second communication component 178; the backup power component 172 is disposed on the surface of the second partition plate 128 facing the installation space 160; the power switching switch 174 is disposed on the surface of the third partition plate 134 facing the installation space 160; the first communication component 176 is disposed on the surface of the second partition plate 128 facing the installation space 160, and along the left-right direction of the cabin 110, the first communication component 176 is located on the side of the backup power component 172 close to the power switching switch 174; the second communication component 178 is disposed on the surface of the third partition plate 134 facing the installation space 160, and along the direction from the bottom plate 112 to the top plate 114, the second communication component 178 is located below the power switching switch 174.

[0090] In this embodiment, the backup power component 172 is an uninterruptible power supply module, used to continuously provide low-voltage power to communication and control equipment when the external main power supply is interrupted, ensuring that the system monitoring and protection functions are not interrupted. The input terminal of the backup power component 172 is connected to the external auxiliary power supply, and the output terminal of the backup power component 172 is connected to the control circuit and communication circuit of the low-voltage power distribution component 170.

[0091] The power transfer switch 174 is a dual-power automatic transfer switch used to automatically switch between the main power supply and the backup power supply to ensure the continuity of power supply to the load. The two input terminals of the power transfer switch 174 are connected to the main power supply circuit and the output terminal of the backup power component 172, respectively, and the output terminal of the power transfer switch 174 is connected to the downstream power distribution load.

[0092] The first communication component 176 and the second communication component 178 are both communication modules of the energy management system, used to collect voltage, current and switch status data of each power distribution circuit of the whole machine, upload the data to the upper-level monitoring system, and receive control commands issued. The signal acquisition terminals of the first communication component 176 and the second communication component 178 are respectively connected to each power distribution component, and the communication terminals of the first communication component 176 and the second communication component 178 are connected to the external monitoring line.

[0093] The backup power component 172 and the first communication component 176 are jointly arranged on the front mounting surface of the second partition plate 128, and are arranged horizontally along the left-right direction of the hull 110. The first communication component 176 is located on the side of the third partition plate 134, adjacent to the power switching switch 174 on the third partition plate 134. The power switching switch 174 and the second communication component 178 are jointly arranged on the side mounting surface of the third partition plate 134, and are arranged vertically along the direction from the bottom plate 112 to the top plate 114. The second communication component 178 is located directly below the power switching switch 174. The overall layout is functionally divided, with the main and backup power and main communication modules arranged on the front mounting surface, and the power switching and secondary communication modules arranged on the side mounting surfaces.

[0094] In related technologies, communication modules are placed separately in independent communication cabinets, separate from the main power distribution cabinet. This requires the fabrication of separate sheet metal cabinets, which takes up more internal space. Furthermore, the components are scattered across two cabinets, resulting in long wiring distances. Maintenance requires opening two cabinet doors separately, making operation inconvenient.

[0095] This invention integrates backup power components, power switching switches, and two types of communication components directly onto the mounting surface of the compartment bulkhead, eliminating the need for a separate communication cabinet and saving on additional sheet metal materials, thus reducing material costs. Functional modules are arranged in functional zones on the front and side bulkheads, with clear zoning. Opening the door of the low-voltage power distribution room allows direct access to all components, facilitating daily inspections and fault maintenance, and solving the problems of overlapping functional areas and inconvenient maintenance associated with traditional solutions. Simultaneously, the centralized arrangement of components shortens internal wiring length, reduces line losses, and eliminates the need for separate heat dissipation, shock absorption, and protection structures for the communication cabinet, reducing overall design complexity.

[0096] Optionally, the operating handle of the power switch 174 faces the front of the installation space 160, and the position of the operating handle corresponds to the position of the observation window on the door panel 150, so that the operator can directly check the open / closed status of the switch without opening the door panel 150.

[0097] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments of the present invention, optionally, the boost converter assembly further includes a first extension plate 192; the first extension plate 192 is disposed on the surface of the second partition plate 128 facing the mounting space 160; the first communication component 176 and the backup power component 172 are respectively connected to the first extension plate 192 so as to be disposed on the second partition plate 128 through the first extension plate 192.

[0098] In this embodiment, the first extension plate 192 is used to expand the mounting plane of the second partition plate 128, providing a unified mounting reference surface for the backup power component 172 and the first communication component 176, thus avoiding the impact of densely opening holes directly on the second partition plate 128 on the structural strength of the partition plate 120. Both the backup power component 172 and the first communication component 176 are fixed to the surface of the first extension plate 192 with bolts, and then the first extension plate 192 is integrally fixed to the second partition plate 128, achieving modular pre-assembly and overall disassembly.

[0099] Optionally, the first extension plate 192 has multiple sets of mounting holes pre-drilled on its surface, allowing the left-right relative positions of the backup power component 172 and the first communication component 176 to be adjusted according to actual layout requirements.

[0100] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments of the present invention, optionally, a first power distribution area 130 is provided on the surface of the second partition plate 128 facing the installation space 160, and the first power distribution area 130 is located above the backup power component 172 and the first communication component 176 along the direction from the bottom plate 112 to the top plate 114; the low-voltage power distribution component 170 further includes a first power distribution component 180, which is disposed in the first power distribution area 130; a second power distribution area 124 is provided on the surface of the first partition plate 122 facing the installation space 160; the low-voltage power distribution component 170 further includes a second power distribution component 182, which is disposed in the second power distribution area 124.

[0101] In this embodiment, the first distribution area 130 is a region on the second partition plate 128 specifically used for arranging main distribution circuit devices. The first distribution component 180 consists of AC / DC main circuit busbars and switching devices, used to realize the busbar and on / off control of the main power circuit. The second distribution area 124 is a region on the first partition plate 122 specifically used for arranging secondary distribution circuit devices. The second distribution component 182 consists of branch circuit distribution and protection devices, used to realize the distribution and protection of each branch load.

[0102] The first power distribution area 130 is located in the upper region of the second partition 128, directly above the backup power component 172 and the first communication component 176. The first power distribution component 180 is arranged laterally along the left-right direction of the cabin 110 within the first power distribution area 130. The second power distribution area 124 is located in the upper region of the first partition 122. The second power distribution component 182 is arranged vertically along the direction from the bottom plate 112 to the top plate 114 within the second power distribution area 124. The main power distribution function is concentrated on the front second partition 128, while the distributed power distribution function is arranged on the side first partition 122. The two power distribution areas are independent and do not overlap.

[0103] This invention divides the power distribution function into a main power distribution area and a secondary power distribution area, which are respectively arranged on the front partition and the side partition. The layout is based on voltage level and functional attributes, with main circuits and branch circuits routed separately to avoid interference from intersecting lines. After opening the door 150 degrees, the main power distribution area on the front and the secondary power distribution area on the side are clearly visible. Operators can quickly locate the corresponding devices according to their functional areas, making maintenance and repair convenient and solving the problems of overlapping functional areas and inconvenient maintenance in traditional cabinets.

[0104] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments of the present invention, optionally, the surface of the second partition plate 128 facing the installation space 160 is further provided with a first auxiliary transformer power supply area 132, which is located below the backup power component 172 and the first communication component 176 along the direction from the bottom plate 112 to the top plate 114; the surface of the first partition plate 122 facing the installation space 160 is further provided with a second auxiliary transformer power supply area 126, which is located below the second power distribution area 124 along the direction from the bottom plate 112 to the top plate 114; the low-voltage power distribution component 170 also includes an auxiliary transformer power supply component 184, a part of which is located in the first auxiliary transformer power supply area 132, and another part of which is located in the second auxiliary transformer power supply area 126.

[0105] In this embodiment, the first auxiliary transformer power supply area 132 and the second auxiliary transformer power supply area 126 are functional areas for arranging auxiliary transformer power supply circuit devices. The auxiliary transformer power supply component 184 is a power distribution, switching, and protection device on the low-voltage side of the auxiliary transformer, used to distribute the electrical energy output by the auxiliary transformer to each auxiliary power circuit. The auxiliary transformer power supply component 184 is divided into two parts, which are arranged on two different boards to accommodate different wiring routes.

[0106] The first auxiliary transformer power supply area 132 is located in the lower region of the second partition plate 128, directly below the backup power component 172 and the first communication component 176. The main switch portion of the auxiliary transformer power supply component 184 is arranged within the first auxiliary transformer power supply area 132. The second auxiliary transformer power supply area 126 is located in the lower region of the first partition plate 122, directly below the second power distribution area 124. The branch circuit portion of the auxiliary transformer power supply component 184 is arranged within the second auxiliary transformer power supply area 126. The auxiliary transformer power supply function is concentrated in the lower region of the installation space 160, close to the side of the first partition plate 122, near the incoming line position of the auxiliary transformer room 210.

[0107] This invention divides the auxiliary transformer power supply function into two separate power supply zones, located at the lower part of the front and side partitions, respectively, close to the incoming line side of the auxiliary transformer compartment 210, thus shortening the wiring distance of the auxiliary transformer incoming line. During operation and maintenance, the auxiliary transformer power supply related components can be directly located in the lower area, solving the problem of traditional cabinet functional areas being cross-distributed and inconvenient for maintenance.

[0108] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments of the present invention, the low-voltage power distribution component 170 may optionally include an auxiliary transformer protection module 186, a grounding copper busbar 188, and an auxiliary power supply component 190; the auxiliary transformer protection module 186 is disposed on the surface of the first partition plate 122 facing the installation space 160 and located on the side of the second auxiliary transformer power supply area 126; the grounding copper busbar 188 is disposed at the bottom of the installation space 160; the auxiliary power supply component 190 is disposed on the surface of the third partition plate 134 facing the installation space 160 and is arranged at intervals from the second communication component 178.

[0109] In this embodiment, the auxiliary transformer protection module 186 is a surge protector and fuse-type protective device used to provide surge and overcurrent protection for the auxiliary transformer power supply circuit, preventing damage to downstream equipment from lightning strikes and overvoltage. The grounding copper busbar 188 is the common grounding reference conductor for the entire unit, used to connect the grounding terminals of each device to achieve grounding protection. The auxiliary power supply component 190 is an auxiliary power conversion device for the control circuit, used to convert the input voltage into the operating voltage required by communication and control devices, and to power control devices such as the second communication component 178.

[0110] This invention arranges three types of auxiliary components near their corresponding functional areas: the protection module is close to the auxiliary transformer power supply area, the auxiliary power supply component 190 is close to the communication component, and the grounding copper busbar 188 is uniformly arranged at the bottom. Each component is arranged according to its function, resulting in short wiring distances and neat wiring. All components are clearly zoned, allowing for quick location based on function during operation and maintenance, thus solving the problems of chaotic layout and inconvenient maintenance in traditional cabinets.

[0111] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments of the present invention, optionally, the boost converter assembly further includes a second extension plate 194 and a monitoring module 196; the second extension plate 194 is connected to the surface of the first partition plate 122 facing the mounting space 160, and the second extension plate 194 extends from the first partition plate 122 toward the third partition plate 134; the monitoring module 196 is disposed on the side surface of the second extension plate 194 opposite to the second partition plate 128.

[0112] In this embodiment, the second extension plate 194 is a cantilevered mounting plate, used to extend the monitoring module 196 towards the center of the mounting space 160, avoiding the inconvenience of observing the monitoring module 196 against the side wall. The monitoring module 196 is a status monitoring and indicating device for the power distribution circuit, used to display the voltage, current, and on / off status of the power distribution circuit in real time, making it convenient for operators to intuitively view the operating status.

[0113] One end of the second extension plate 194 is fixed to the middle area of ​​the first partition plate 122, and the other end extends horizontally into the installation space 160. The monitoring module 196 is fixedly installed on the side surface of the second extension plate 194 facing the door panel 150, with the display surface facing the opening of the low-voltage power distribution room 140. After the operator opens the door panel 150, they can directly see the display interface of the monitoring module 196.

[0114] In some embodiments of the present invention, the step-up converter assembly optionally includes an auxiliary transformer, a main transformer, and a high-voltage switchgear; the auxiliary transformer is disposed inside the auxiliary transformer compartment 210; the main transformer is disposed inside the main transformer compartment 212; and the high-voltage switchgear is disposed inside the high-voltage compartment 208.

[0115] In this embodiment, an auxiliary transformer is installed inside the auxiliary transformer compartment 210, a main transformer is installed inside the main transformer compartment 212, and a high-voltage switchgear is installed inside the high-voltage compartment 208. This invention integrates the functions of low-voltage power distribution, voltage boosting, high-voltage power distribution, and auxiliary power supply into the step-up converter assembly. The overall integration is high, and each functional area is clearly defined and independent, facilitating on-site installation and maintenance management.

[0116] In some embodiments of the present invention, an integrated energy storage converter and boost converter is proposed, including the boost converter component as described in any of the above embodiments.

[0117] In this embodiment, the energy storage converter-boost integrated unit proposed in this invention is an integrated power device that integrates functions such as power conversion, voltage boosting, power distribution control, and monitoring and protection within the same prefabricated cabin 110. It is mainly used in scenarios such as electrochemical energy storage power stations and wind-solar-storage integrated power stations. The core function of the energy storage converter-boost integrated unit is to convert the low-voltage DC power output from the external battery cluster into AC power that conforms to the grid standard, and then boost it to the grid access voltage level through a boosting stage before finally connecting it to the public power grid.

[0118] The integrated energy storage converter and booster unit includes the booster converter component in any of the above embodiments, and therefore possesses all the technical effects of the aforementioned booster converter component. By eliminating the independent low-voltage distribution cabinet and directly reusing the partition plate 120 of the compartment 110 as the installation carrier for the power distribution components, the material waste caused by the double sheet metal overlap between the compartment wall and the distribution cabinet is eliminated, reducing the overall material cost and assembly time. At the same time, the pre-reserved gap for the hoisting of the distribution cabinet is eliminated, improving the utilization rate of the internal space. Through the structure of the low-voltage distribution room 140 and the auxiliary transformer room 210 being connected at the top and sharing a heat dissipation duct, the entire unit does not need to configure a separate heat dissipation system for the low-voltage distribution room 140, reducing the total number of heat dissipation components 206 and simplifying the design and assembly process of the overall heat dissipation system.

[0119] Optionally, the integrated energy storage converter and boost converter also includes a converter unit and a transformer unit. The transformer unit, located inside the main transformer compartment 212, is used to boost low-voltage AC power to the grid connection voltage level. The converter unit and the boost converter assembly are arranged along the left-right direction of the integrated unit. The DC side of the converter unit is used to connect to the external battery pack, the AC side of the converter unit is electrically connected to the low-voltage side of the transformer unit, and the high-voltage side of the transformer unit is used to connect to the external power grid. The converter unit is responsible for converting AC and DC power and regulating power, achieving bidirectional charging and discharging control. The transformer unit is responsible for voltage level conversion to meet grid connection voltage requirements. Both are integrated with the boost converter assembly inside the same compartment 110, eliminating the need for separate converter cabinets, transformer cabinets, and other independent cabinets, reducing the overall equipment footprint, shortening the length of connecting cables between units, and reducing line losses and on-site installation costs.
