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 low-voltage distribution room and auxiliary transformer room of a step-up converter are two independent, enclosed chambers with no airflow communication. To meet the heat dissipation requirements of the electrical components in the two chambers, independent heat dissipation structures are required in both chambers to ventilate and cool them separately. These two independently configured heat dissipation structures result in a large number of components and a complex overall structure for the step-up converter. 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 first partition, and a heat dissipation unit.

[0008] During operation, the heat dissipation unit draws air from the auxiliary transformer chamber and discharges it to the outside, creating a negative pressure inside the auxiliary transformer chamber. Air from the low-voltage distribution chamber flows into the auxiliary transformer chamber through the first gap to replenish it, carrying heat from the low-voltage distribution chamber into the auxiliary transformer chamber. Finally, all the heat is discharged to the outside of the chamber with the heat dissipation unit, thus achieving the simultaneous heat dissipation of two chambers by one heat dissipation structure.

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 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 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments of the present invention, a boost converter assembly is proposed, comprising a housing 110, a first partition 120, and a heat dissipation unit 140. The housing 110 includes a bottom plate 112, a top plate 114 disposed opposite to the bottom plate 112, and a front plate 116 connecting the bottom plate 112 and the top plate 114; the first partition 120 is disposed inside the housing 110, separating the interior of the housing 110 to form a low-voltage distribution room 132 and an auxiliary transformer room 134, the first partition 120 having a first surface 122 facing the low-voltage distribution room 132 and a second surface 124 facing the auxiliary transformer room 134; a first gap 130 is formed between the edge of the first partition 120 and the inner wall surface 119 of the housing 110, and the low-voltage distribution room 132 communicates with the auxiliary transformer room 134 through the first gap 130; the heat dissipation unit 140 is disposed inside the auxiliary transformer room 134.

[0046] In this embodiment, the cabin 110 provides the basic framework for external support and protection of the entire assembly. The bottom plate 112, top plate 114, and front plate 116 together constitute part of the basic wall surface of the cabin 110. The first partition 120 is used to divide the internal space of the cabin 110, separating two independent functional chambers, each housing different types of electrical devices. The first gap 130 forms an airflow channel between the two chambers, allowing air to circulate between the two sides. The heat dissipation unit 140 is used to drive the airflow within the cabin, dissipating heat from the chamber to the outside of the cabin 110.

[0047] In related technologies, the edges of the first partition are all flush with the inner wall of the cabin, and the low-voltage power distribution room and the auxiliary transformer room are two completely independent, closed chambers with no airflow communication. To meet the heat dissipation requirements of the two chambers, an independent heat dissipation structure needs to be installed in each chamber to dissipate heat. The two independently configured heat dissipation structures result in a large number of components in the boost converter assembly, a complex overall structure, low equipment integration, and high manufacturing costs.

[0048] In response to the above situation, the present invention has made targeted improvements to the partition structure. A first gap 130 is reserved between the edge of the first partition 120 and the inner wall 119 of the cabin 110 to open up the airflow path between the two chambers. The heat dissipation part 140 is only set inside the auxiliary transformer chamber 134, and the independent heat dissipation structure of the low-voltage power distribution chamber 132 is eliminated.

[0049] During operation, the heat dissipation unit 140 draws air from the auxiliary transformer chamber 134 and discharges it outside the cabin, creating a negative pressure inside the auxiliary transformer chamber 134. Air from the low-voltage distribution chamber 132 flows into the auxiliary transformer chamber 134 through the first gap 130 to replenish it, while carrying heat from the low-voltage distribution chamber 132 into the auxiliary transformer chamber 134. Finally, all the heat is discharged outside the cabin with the heat dissipation unit 140, thus achieving the simultaneous heat dissipation of two chambers by one heat dissipation structure.

[0050] By shortening the first partition 120, the low-voltage distribution room 132 and the auxiliary transformer room 134 are connected, and the heat dissipation duct can be shared by the two chambers. The above-described structure of the present invention reduces the total number of heat dissipation components, simplifies the overall structure of the components, improves the integration of the equipment, and reduces component and assembly costs.

[0051] Optionally, the cross-sectional shape of the first gap 130 can be set to rectangular, trapezoidal or arc-shaped, and adjusted according to the duct resistance requirements.

[0052] Optionally, the edge of the first gap 130 can be chamfered to reduce air resistance when airflow passes through.

[0053] Optionally, a heat-conducting structure can be provided on the surface of the first partition 120 to help transfer heat within the low-voltage distribution room 132 and improve overall heat dissipation efficiency.

[0054] like Figure 1 As shown, in some embodiments of the present invention, optionally, the first gap 130 is located between the side edge of the first partition 120 away from the bottom plate 112 and the top plate 114; along the direction from the bottom plate 112 to the top plate 114, the extension dimension of the first gap 130 is less than or equal to half the height of the first partition 120.

[0055] In this embodiment, the present invention specifically defines the position and size of the first gap 130. The first gap 130 is located between the top end of the first partition 120 and the top plate 114. That is, the present invention shortens the first partition 120 along the height direction so that the top end of the first partition 120 does not contact the top plate 114, forming a horizontal connecting gap between the top edge of the first partition 120 and the lower surface of the top plate 114.

[0056] Along the direction from the bottom plate 112 to the top plate 114, the extension dimension of the first gap 130 is less than or equal to half the height of the first partition 120. This dimensional relationship is set because the first partition 120 also serves as the mounting base for the low-voltage power distribution component 166, requiring sufficient solid plate surface for mounting the device. An excessively large gap would result in insufficient mounting area. This ratio ensures both sufficient ventilation area between the two chambers to meet heat dissipation requirements and sufficient effective mounting area for the first partition 120 to support the installation of the low-voltage power distribution component 166.

[0057] In practical applications, the extension dimension of the first gap 130 can be adjusted appropriately according to the total installation area requirements of the low-voltage power distribution components 166. When the number of low-voltage power distribution components 166 is small and the installation area occupied is small, the extension dimension of the first gap 130 can be appropriately increased to improve ventilation. When the number of low-voltage power distribution components 166 is large and the installation area occupied is large, the extension dimension of the first gap 130 can be appropriately reduced to ensure sufficient installation space.

[0058] In this embodiment, the extension dimension of the first gap 130 refers to the vertical distance between the top edge of the first partition 120 and the lower surface of the top plate 114 along the direction from the bottom plate 112 to the top plate 114, which is the width of the first gap 130 in the height direction.

[0059] Optionally, the flow area of ​​the first gap 130 can be configured to be greater than or equal to the air intake area of ​​the heat dissipation section 140 to avoid the gap becoming a bottleneck in the airflow and limiting the heat dissipation airflow.

[0060] like Figure 1 As shown, in some embodiments of the present invention, optionally, the orthographic projection of the heat dissipation portion 140 on the plane where the first partition 120 is located overlaps at least partially with the first gap 130.

[0061] In this embodiment, the present invention defines the relative position of the heat dissipation part 140 and the first gap 130, so that the heat dissipation part 140 and the first gap 130 are arranged opposite to each other. Specifically, the orthographic projection of the heat dissipation part 140 on the plane where the first partition plate 120 is located overlaps with at least a portion of the first gap 130.

[0062] By adopting the above-mentioned location setting, the heat dissipation part 140 in the auxiliary transformer room 134 can be used more directly to dissipate heat from the low-voltage power distribution room 132, shortening the airflow path from the low-voltage power distribution room 132 into the heat dissipation part 140, reducing wind resistance loss, and improving the heat dissipation efficiency of the low-voltage power distribution room 132.

[0063] The orthographic projection of the heat dissipation unit 140 onto the plane of the first partition 120 refers to the pattern formed by projecting the entire heat dissipation unit 140 onto the plane of the first partition 120 along a direction perpendicular to the surface of the first partition 120. "At least partially overlapping with the first gap 130" means that the projected pattern and the projection area of ​​the first gap 130 on the same plane overlap. The overlapping area can be one-third, one-half, or all of the area of ​​the first gap 130. The higher the overlap ratio, the better the airflow.

[0064] Optionally, the orthographic projection of the heat dissipation unit 140 on the plane of the first partition 120 can completely cover the first gap 130, so that all the airflow flowing out through the first gap 130 can directly enter the air intake range of the heat dissipation unit 140, thereby maximizing the efficiency of airflow utilization.

[0065] Optionally, the air inlet face of the heat dissipation section 140 can be arranged parallel to the extension direction of the first gap 130, so that the airflow enters the heat dissipation section 140 in a smoother direction and reduces turbulence loss.

[0066] Optionally, an air guide channel structure is provided between the first gap 130 and the heat dissipation part 140. The air inlet side of the air guide channel corresponds to the first gap 130, and the air outlet side corresponds to the air inlet end of the heat dissipation part 140, so as to further gather the airflow and improve the heat dissipation efficiency.

[0067] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments of the present invention, optionally, a first air intake grille 150 is provided in the area of ​​the front panel 116 corresponding to the auxiliary transformer room 134, and the auxiliary transformer room 134 is connected to the outside of the cabin 110 through the first air intake grille 150; a connecting plate 152 is provided between the first partition 120 and the front panel 116 on one side edge near the front panel 116, one end of the connecting plate 152 is connected to the first partition 120, and the other end of the connecting plate 152 is connected to the front panel 116; at least one ventilation hole 154 is provided on the connecting plate 152, and the low-voltage power distribution room 132 is connected to the auxiliary transformer room 134 through the ventilation hole 154.

[0068] In this embodiment, the present invention features an air intake structure. A first air intake grille 150 is provided on the front panel 116 corresponding to the area of ​​the auxiliary transformer chamber 134, and the auxiliary transformer chamber 134 is connected to the outside of the cabin 110 through the first air intake grille 150. Cold air from outside can enter the auxiliary transformer chamber 134 from the outside of the cabin 110 through the first air intake grille 150, providing a fresh air source for the heat dissipation process.

[0069] Furthermore, the present invention also includes a connecting plate 152. A connecting plate 152 is disposed between the first partition 120 and the front plate 116 on one side edge near the front plate 116. One end of the connecting plate 152 is connected to the first partition 120, and the other end is connected to the front plate 116. At least one ventilation hole 154 is provided on the connecting plate 152, through which the low-voltage distribution room 132 communicates with the auxiliary transformer room 134. Air in the auxiliary transformer room 134 can enter the low-voltage distribution room 132 through the ventilation hole 154, forming an auxiliary airflow channel between the two chambers on the front side.

[0070] Figure 3 The arrows in the diagram indicate the airflow path. When the heat dissipation unit 140 is working, it draws air outward, creating a negative pressure inside the auxiliary transformer chamber 134. External cold air enters the auxiliary transformer chamber 134 through the first air inlet grille 150. The air entering the auxiliary transformer chamber 134 is divided into two parts. One part flows directly inside the auxiliary transformer chamber 134, carrying away heat from the components within. The other part enters the low-voltage distribution chamber 132 through the ventilation holes 154 on the connecting plate 152, cooling the components within the low-voltage distribution chamber 132. Within the low-voltage distribution chamber 132, the air flows upward, then flows back to the auxiliary transformer chamber 134 through the first gap 130 at the top, finally carrying heat with it and being discharged outside the chamber through the heat dissipation unit 140.

[0071] Through the above structural design, the present invention supplements the airflow channel of the ventilation hole 154 of the connecting plate 152 on the front side, and together with the first gap 130 at the top, forms a complete airflow circulation path from bottom to top within the low-voltage power distribution room 132, avoiding airflow dead zones within the low-voltage power distribution room 132 and improving the heat dissipation uniformity inside the low-voltage power distribution room 132. Meanwhile, the first air inlet grille 150 is separately installed in the auxiliary transformer room 134, resulting in a short air inlet path and low air inlet resistance.

[0072] Optionally, the number of ventilation holes 154 on the connecting plate 152 can be set to multiple, and the multiple ventilation holes 154 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 132.

[0073] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, in some embodiments of the present invention, optionally, the cabin 110 further includes a side plate 118, the side plate 118 and the first partition 120 are arranged opposite each other at intervals along the left and right directions of the cabin 110, and the side plate 118, the first partition 120, the bottom plate 112 and the top plate 114 together form an auxiliary transformer chamber 134; the heat dissipation part 140 includes a heat dissipation fan 142, the heat dissipation fan 142 is disposed on the side plate 118, the air inlet of the heat dissipation fan 142 faces the interior of the auxiliary transformer chamber 134, and the air outlet of the heat dissipation fan 142 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 142 and the top plate 114 is less than the distance between the heat dissipation fan 142 and the bottom plate 112.

[0074] In this embodiment, the present invention specifies the specific form of the side plate 118 and the heat dissipation part 140 of the cabin 110. The cabin 110 also includes the side plate 118, and the side plate 118 and the first partition 120 are along the left and right direction of the cabin 110 (e.g., Figure 4 (As indicated by the middle arrow A) The side plate 118, the first partition plate 120, the bottom plate 112, and the top plate 114 are arranged at intervals relative to each other to form the auxiliary transformer chamber 134. The side plate 118 serves as the side wall of the auxiliary transformer chamber 134, providing an installation carrier for the heat dissipation unit 140, and at the same time enclosing the lateral boundary of the auxiliary transformer chamber 134.

[0075] The heat dissipation unit 140 includes a heat dissipation fan 142, which is disposed on the side plate 118. The air inlet of the heat dissipation fan 142 faces the interior of the auxiliary transformer compartment 134, and the air outlet of the heat dissipation fan 142 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 142 and the top plate 114 is less than the distance between the heat dissipation fan 142 and the bottom plate 112. The heat dissipation fan 142 is arranged in the upper region of the side plate 118, close to the top plate 114.

[0076] During operation, the cooling fan 142 starts, drawing in hot air from the auxiliary transformer chamber 134 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 142 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 134, preventing heat from accumulating at the top of the cabin 110.

[0077] The cooling fan 142 is mounted on the side plate 118, which is a simple installation structure. During maintenance, the fan can be directly removed and installed from the outside of the cabin 110 without entering the auxiliary transformer room 134. The upper arrangement of the fan can make full use of the natural law of hot air rising, improve the exhaust efficiency, and at the same time make room for the space under the side plate 118, so as not to affect the arrangement of components in the auxiliary transformer room 134.

[0078] Optionally, a rain cover can be installed on the outside of the air outlet of the cooling fan 142 to prevent rainwater and debris from entering the compartment from the fan location.

[0079] Optionally, the cooling fan 142 can be configured to have an adjustable speed, adjusting the speed according to the temperature inside the auxiliary transformer room 134 and the low-voltage distribution room 132, thereby reducing operating energy consumption while meeting heat dissipation requirements.

[0080] In this embodiment, the heat dissipation unit 140 can also be a passive or active heat dissipation structure such as a heat dissipation coil, heat dissipation fins, water-cooled heat dissipation components, air-cooled heat dissipation modules, and heat exchange radiators.

[0081] In some embodiments of the present invention, optionally, an air guide plate is also provided inside the auxiliary transformer chamber 134. The air guide plate is located between the first gap 130 and the cooling fan 142 and is used to guide the airflow to the cooling fan 142.

[0082] In this embodiment, an air guiding structure is added inside the auxiliary transformer chamber 134. The air guide plate is disposed between the air outlet side of the first gap 130 and the air inlet side of the cooling fan 142, receiving the airflow flowing out from the first gap 130 and guiding the airflow to the air inlet area of ​​the cooling fan 142. After adding the air guide plate, the diffused airflow can be gathered, reducing the ineffective flow of airflow in the chamber, reducing wind resistance loss, and increasing the effective airflow of the cooling fan 142.

[0083] In some embodiments of the present invention, the heat dissipation unit 140 may optionally include a mounting member disposed on the side surface of the side plate 118 facing the auxiliary transformer chamber 134, and the heat dissipation fan 142 is connected to the side plate 118 through the mounting member.

[0084] In this embodiment, the installation structure of the cooling fan 142 has been refined, and a dedicated mounting component has been added. The mounting component integrates the mounting frame and the air guide cover, thereby realizing the fixed installation and air outlet guidance functions of the cooling fan 142.

Along the front and rear direction of the cabin 110, the door panel 164 is arranged opposite to the second partition 158; the first partition 120, the second partition 158, the third partition 160, the bottom plate 112, the top plate 114 and the door panel 164 together form the low-voltage power distribution room 132.

[0086] In this embodiment, the present invention fully defines the internal partition structure of the cabin 110. The second partition 158 and the front panel 116 are along the front-rear direction of the cabin 110 (e.g., Figure 6 (In the direction indicated by arrow B) the partitions are arranged at intervals. The bottom end of the second partition 158 is connected to the bottom plate 112, and the top end of the second partition 158 is connected to the top plate 114. The side of the second partition 158 away from the low-voltage distribution room 132 forms the high-voltage room 159. The second partition 158 also serves as a shared partition for the low-voltage distribution room 132 and the high-voltage room 159. The third partition 160 and the first partition 120 are arranged opposite each other at intervals along the left and right directions of the cabin 110. The bottom end of the third partition 160 is connected to the bottom plate 112, the top end of the third partition 160 is connected to the top plate 114, the rear end of the third partition 160 is connected to one end of the second partition 158, and the rear end of the first partition 120 is connected to the other end of the second partition 158. The side of the third partition 160 away from the low-voltage power distribution room 132 forms the main transformer room 162. The third partition 160 also serves as a shared partition for the low-voltage power distribution room 132 and the main transformer room 162.

[0087] Door panel 164 is rotatably connected to front panel 116. Door panel 164 is arranged corresponding to opening 133 of low-voltage power distribution room 132. Along the front-rear direction of cabin 110, door panel 164 is opposite to second partition 158. Door panel 164 can open and close around rotation axis. When closed, it covers opening 133 on the front side of low-voltage power distribution room 132. When open, it exposes the internal space of low-voltage power distribution room 132 for personnel to perform device inspection and maintenance operations.

[0088] The first partition 120, the second partition 158, the third partition 160, the bottom plate 112, the top plate 114, and the door panel 164 together form the low-voltage power distribution room 132. The first partition 120, the second partition 158, and the third partition 160 serve as the three side walls of the low-voltage power distribution room 132, the bottom plate 112 and the top plate 114 serve as the bottom and top walls of the low-voltage power distribution room 132, and the door panel 164 serves as the front openable wall of the low-voltage power distribution room 132, together enclosing the complete accommodating space of the low-voltage power distribution room 132.

[0089] This invention directly utilizes the partitions inside the cabin 110 as side walls of the low-voltage power distribution room 132, eliminating the need for separate power distribution cabinets and achieving the reuse of sheet metal structures, thus reducing redundant sheet material usage. Simultaneously, the high-voltage room 159, main transformer room 162, and low-voltage power distribution room 132 are integrated within the same cabin 110, with each functional chamber arranged closely together, improving the space utilization rate inside the cabin 110.

[0090] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments of the present invention, optionally, a second air inlet grille 156 is provided in the area of ​​the door panel 164 corresponding to the low-voltage power distribution room 132, and the low-voltage power distribution room 132 is connected to the outside of the cabin 110 through the second air inlet grille 156; along the direction from the bottom plate 112 to the top plate 114, both the first air inlet grille 150 and the second air inlet grille 156 are arranged close to the bottom plate 112.

[0091] In this embodiment, the present invention supplements the air intake structure of the low-voltage power distribution room 132. A second air intake grille 156 is provided on the door panel 164 corresponding to the area of ​​the low-voltage power distribution room 132, and the low-voltage power distribution room 132 is connected to the outside of the cabin 110 through the second air intake grille 156. External cold air can directly enter the interior of the low-voltage power distribution room 132 through the second air intake grille 156 on the door panel 164, providing an independent air intake path for the low-voltage power distribution room 132.

[0092] Along the direction from the bottom plate 112 to the top plate 114, the first air intake grille 150 and the second air intake grille 156 are both arranged close to the bottom plate 112. Both air intake grilles are located at the lower part of the cabin 110, forming a unified layout for lower air intake, which, together with the upper heat dissipation section 140 exhaust, conforms to the airflow pattern of cold air sinking and hot air rising.

[0093] When the heat dissipation unit 140 is operating, negative pressure is created in both the auxiliary transformer compartment 134 and the low-voltage distribution compartment 132. Part of the external cold air enters the auxiliary transformer compartment 134 through the first air inlet grille 150, carrying away heat from the components inside and flowing upwards. The other part enters the low-voltage distribution compartment 132 directly through the second air inlet grille 156, cooling the components inside and then flowing upwards, entering the auxiliary transformer compartment 134 through the first gap 130 at the top. The two airflows converge at the top of the auxiliary transformer compartment 134 and are then discharged outside the compartment through the heat dissipation unit 140.

[0094] By creating an independent second air intake grille 156 on the door panel 164, the low-voltage power distribution room 132 has a direct external air intake channel, eliminating the need to rely entirely on the ventilation holes 154 on the auxiliary transformer room 134 for air intake. This increases the air intake volume of the low-voltage power distribution room 132 and enhances its heat dissipation capacity. Both air intake grilles are positioned low, working in conjunction with the top exhaust to form a stable bottom-in, top-out airflow duct, ensuring smooth airflow and higher heat dissipation efficiency.

[0095] In some embodiments of the present invention, optionally, the first air inlet grille 150 and the second air inlet grille 156 are both surrounded by multiple grille bars arranged at intervals to form multiple ventilation gaps; and dustproof components are provided on the inner side of the first air inlet grille 150 and / or the second air inlet grille 156.

[0096] In this embodiment, the invention specifies the concrete structure of the two air intake grilles and adds a dustproof filtration structure to improve the cleanliness of the incoming air while ensuring ventilation volume. Multiple grille bars are arranged parallel and spaced along the same direction, with independent ventilation gaps formed between adjacent grille bars. The total area of ​​all ventilation gaps constitutes the total ventilation area of ​​the air intake grille. The dustproof component covers the entire ventilation area of ​​the corresponding air intake grille. When airflow enters the cabin from outside the cabin 110, it must first pass through the ventilation gaps between the grille bars, then be filtered by the dustproof component, and finally enter the cabin.

[0097] like Figure 1 As shown, in some embodiments of the present invention, optionally, the boost converter assembly further includes: a low-voltage power distribution component 166, which is disposed inside the low-voltage power distribution room 132.

[0098] In this embodiment, the boost converter assembly also includes a low-voltage power distribution component 166, which is disposed inside the low-voltage power distribution room 132. The low-voltage power distribution component 166 is a general term for electrical devices that realize functions such as low-voltage power distribution, backup power, and communication, and is directly arranged in the internal space of the low-voltage power distribution room 132.

[0099] This invention eliminates the need for a separate power distribution cabinet structure. Instead, it utilizes the sheet metal partition between the low-voltage distribution compartment 132 and the high-voltage compartment 159 of the boost converter cabin as the device mounting plate on the front of the cabinet. The partition between the low-voltage distribution compartment 132 and the auxiliary transformer compartment 134 serves as the device mounting plate on the right side of the cabinet. The partition between the low-voltage distribution compartment 132 and the main transformer compartment 162 serves as the mounting plate on the left side of the cabinet. The bottom and top sheet metal of the boost converter cabin serve as the bottom and top surfaces of the cabinet. The door panel 164 of the low-voltage distribution compartment 132 of the boost converter cabin serves as the door panel of the cabinet. This effectively saves sheet metal materials and reduces material costs.

[0100] Electrical components are directly installed inside the low-voltage distribution room 132, saving the space occupied by the distribution cabinet itself. This increases the usable internal space of the low-voltage distribution room 132 compared to a structure with a distribution cabinet, providing more operating space for subsequent maintenance of the components and facilitating operation.

[0101] This invention eliminates the need for separate design of power distribution cabinets, thus avoiding the need to consider specific issues such as IEC certification, seismic resistance, and heat dissipation of power distribution cabinets. This reduces the number of factors to consider during the design phase, lowers the complexity of the design, and shortens the product design cycle.

[0102] 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 166 includes: a backup power component 168, which is disposed on the surface of the second partition 158 facing the low-voltage power distribution room 132; a power switching switch 170, which is disposed on the surface of the third partition 160 facing the low-voltage power distribution room 132; a first communication component 172, which is disposed on the surface of the second partition 158 facing the low-voltage power distribution room 132, and along the left-right direction of the cabin 110, the first communication component 172 is located on the side of the backup power component 168 close to the power switching switch 170; and a second communication component 174, which is disposed on the surface of the third partition 160 facing the low-voltage power distribution room 132, and along the direction from the bottom plate 112 to the top plate 114, the second communication component 174 is located below the power switching switch 170.

[0103] In this embodiment, the backup power component 168 is disposed on the surface of the second partition 158 facing the low-voltage distribution room 132. The backup power component 168 refers to an uninterruptible power supply device, used to continuously provide power when the external main power supply fails, ensuring the normal operation of power distribution, communication and other functions. Arranging the backup power component 168 on the second partition 158, that is, the inner wall of the front of the low-voltage distribution room 132, facilitates operation and maintenance by personnel from the front.

[0104] A power transfer switch 170 is located on the surface of the third partition 160 facing the low-voltage distribution room 132. The power transfer switch 170 is used to switch between the main power supply and the backup power supply, ensuring continuous power supply. Placing the power transfer switch 170 on the third partition 160, which is the inner left wall of the low-voltage distribution room 132, and separating it from the backup power component 168, avoids electromagnetic interference from high-current switching on other devices, and also allows for a more efficient wiring path.

[0105] The first communication component 172 is disposed on the surface of the second partition 158 facing the low-voltage power distribution room 132, along the length of the cabin 110. The first communication component 172 is located on the side of the backup power component 168 near the power switching switch 170. The first communication component 172 is used to realize the functions of equipment operation status monitoring, data uploading and remote communication. It is arranged on the same side as the backup power component 168 to facilitate the wiring connection between the two and shorten the length of the communication cable.

[0106] The second communication component 174 is disposed on the surface of the third partition 160 facing the low-voltage distribution room 132, along the direction from the bottom plate 112 to the top plate 114, and is located below the power switching switch 170. The second communication component 174 is used to assist in collecting operating data from other chambers such as the auxiliary transformer room 134 and the main transformer room 162. It is arranged on the same side as the power switching switch 170 for easy access to the power distribution circuit and to obtain power supply status information.

[0107] In related technologies, conventional communication modules are typically placed in dedicated cabinets. This invention, by adjusting the position of the backup power module and the switch position on the left side panel, directly integrates the communication module into the low-voltage distribution room, eliminating the need for a separate communication cabinet and further improving integration. Traditional distribution cabinets suffer from limited space due to the constraints of internal beams and door panels, resulting in overlapping functional areas and inconvenient maintenance. This invention solves the problem of chaotic layout and maintenance difficulties by arranging specific functional modules in a faceted and zoned manner, clearly defining the location of each module.

[0108] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18As shown, in some embodiments of the present invention, optionally, the low-voltage power distribution component 166 further includes: a first power distribution component 176, which is disposed on the surface of the second partition 158 facing the low-voltage power distribution room 132, along the direction from the bottom plate 112 to the top plate 114, and is located above the backup power component 168 and the first communication component 172; a second power distribution component 178, which is disposed on the surface of the first partition 120 facing the low-voltage power distribution room 132; and an auxiliary transformer power supply component 180. A portion of the auxiliary transformer power supply component 180 is disposed on the surface of the second partition 158 facing the low-voltage distribution room 132, and is located below the backup power component 168 and the first communication component 172 along the direction from the bottom plate 112 to the top plate 114; another portion of the auxiliary transformer power supply component 180 is disposed on the surface of the first partition 120 facing the low-voltage distribution room 132, and is located below the second power distribution component 178 along the direction from the bottom plate 112 to the top plate 114; the auxiliary transformer protection module 182 is disposed on the surface of the first partition 120 facing the low-voltage distribution room 132.

[0109] In this embodiment, the first power distribution component 176 is disposed on the surface of the second partition 158 facing the low-voltage power distribution room 132, along the direction from the bottom plate 112 to the top plate 114. The first power distribution component 176 is located above the backup power component 168 and the first communication component 172. The first power distribution component 176 is a front-facing power distribution component, mainly used to distribute the power of the low-voltage main circuit and supply power to each branch circuit. Arranging it in the upper area of ​​the front partition conforms to the wiring habit of power distribution devices entering from the top and exiting from the bottom, making it convenient for the main incoming cable to be connected from the top.

[0110] The second power distribution component 178 is disposed on the surface of the first partition 120 facing the low-voltage distribution room 132. The second power distribution component 178 is a side-mounted power distribution component, mainly used to distribute branch circuit power to the devices in the auxiliary transformer room 134. Its placement on the first partition 120, which is the right inner wall of the low-voltage distribution room 132, close to the auxiliary transformer room 134, facilitates convenient power supply to the devices within the auxiliary transformer room 134, shortens the length of power supply cables, and reduces line losses.

[0111] A portion of the auxiliary transformer power supply component 180 is disposed on the surface of the second partition 158 facing the low-voltage distribution room 132, and is located below the backup power component 168 and the first communication component 172 along the direction from the bottom plate 112 to the top plate 114; another portion of the auxiliary transformer power supply component 180 is disposed on the surface of the first partition 120 facing the low-voltage distribution room 132, and is located below the second power distribution component 178 along the direction from the bottom plate 112 to the top plate 114. The auxiliary transformer power supply component 180 is used to supply power for the auxiliary transformer's control, heat dissipation, and other auxiliary functions. It adopts a split arrangement across two mounting surfaces, which can accommodate power supply units with different functions, while making full use of the lower space of the two partitions to improve space utilization.

[0112] The auxiliary transformer protection module 182 is disposed on the surface of the first partition 120 facing the low-voltage distribution room 132, and is located on one side of another part of the auxiliary transformer power supply component 180 along the length of the cabin 110. The auxiliary transformer protection module 182 is used to protect the auxiliary transformer power supply circuit from overload, short circuit, and leakage, and promptly cuts off the circuit when an abnormality occurs in the power supply circuit, protecting the electrical components on the auxiliary transformer side. Its proximity to the side portion of the auxiliary transformer power supply component 180 results in a short wiring distance between them and a more timely protection response.

[0113] By using the above-mentioned layout method of dividing the space into sections and layers, power distribution, power supply, and protection devices with different functions are arranged on the corresponding installation surfaces and height areas. The functional zoning is clear and the wiring path is well-defined, which not only improves the utilization rate of the cabin space, but also makes it easier for subsequent maintenance personnel to quickly locate the corresponding functional devices, thereby improving maintenance efficiency.

[0114] 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 166 may optionally include a grounding copper busbar 184 and an auxiliary power supply component 186; the grounding copper busbar 184 is disposed on the surface of the base plate 112 facing the low-voltage power distribution room 132; the auxiliary power supply component 186 is disposed on the surface of the third partition 160 facing the low-voltage power distribution room 132, and is located below the second communication component 174 along the direction from the base plate 112 to the top plate 114.

[0115] In this embodiment, the low-voltage power distribution component 166 further includes a grounding copper busbar 184 and an auxiliary power supply component 186. The grounding copper busbar 184 is disposed on the surface of the base plate 112 facing the low-voltage power distribution room 132. The grounding copper busbar 184 is the common grounding conductor in the low-voltage power distribution system. All electrical devices that require grounding are connected to the grounding copper busbar 184 through grounding wires to achieve unified grounding and ensure the safety of equipment operation. Arranging the grounding copper busbar 184 on the base plate 112, at a low position and close to the grounding terminals of each device, facilitates the wiring of each device nearby and complies with the safety specifications for grounding wiring.

[0116] The auxiliary power supply component 186 is disposed on the surface of the third partition 160 facing the low-voltage distribution room 132, and is located below the second communication component 174 along the direction from the bottom plate 112 to the top plate 114. The auxiliary power supply component 186 is used to convert the input high-voltage AC power into low-voltage DC power to provide operating power for low-voltage control devices such as communication and monitoring devices. Arranging it in the lower area of ​​the third partition 160, on the same plane as the communication component and close to it, shortens the length of the power supply cable, reduces voltage drop loss, and also reduces vibration in the lower area, which is conducive to the stable operation of the auxiliary power supply component 186.

[0117] 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 boost converter assembly further includes a mounting plate 188 and a monitoring module 190. The mounting plate 188 is disposed inside the low-voltage distribution room 132. One edge of the mounting plate 188 is connected to the surface of the first partition 120 facing the low-voltage distribution room 132. The mounting plate 188 extends toward the third partition 160. The surface of the mounting plate 188 is arranged opposite to the surface of the second partition 158 facing the low-voltage distribution room 132. The monitoring module 190 is disposed on the surface of the mounting plate 188.

[0118] In this embodiment, the present invention adds a suspended installation structure and a monitoring module 190 in the low-voltage power distribution room 132. The monitoring module 190 can integrate one or more functions such as temperature and humidity acquisition, smoke detection and partial discharge detection.

[0119] 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.

[0120] 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. It is mainly used in electrochemical energy storage power stations, wind-solar-storage integrated power stations, and other similar scenarios. 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 grid standards, then boost it to the grid access voltage level through a boosting stage, and finally connect it to the public power grid.

[0121] 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 sharing a cooling duct between the low-voltage distribution room 132 and the auxiliary transformer room 134, the entire unit eliminates the need for a separate cooling system for the low-voltage distribution room 132, reducing the total number of 140 cooling components and simplifying the design and assembly process of the overall cooling system. Furthermore, by using the partition sheet metal inside the cabin 110 as a mounting plate 188 for power distribution devices, a separate power distribution cabinet is eliminated, reducing the overall material cost and assembly time, while simultaneously improving the utilization rate of the cabin space.

[0122] 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 162, 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 length of the integrated energy storage converter and boost converter. 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.
