[0041] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0042] See Figure 1 and Figure 2 As shown, in this embodiment, the cabinet assembly 100 includes a first partition 110, a second partition 120, a first partition 130, and a second partition 140. The structure of the second partition 120 is the same as that of the first partition 110. The second partition 120 is spaced apart on one side of the first partition 110, and the second partition 120 is parallel or approximately parallel to the first partition 110. The second partition 120 is centered and aligned with the first partition 110, that is, the orthographic projection of the second partition 120 onto the first partition 110 coincides with the first partition 110.

[0043] A first partition 130 is disposed between a first partition 110 and a second partition 120, and is perpendicular to both the first partition 110 and the second partition 120. Both the first partition 110 and the second partition 120 are rectangular structures, with their opposite sides parallel to the first partition 130. The first partition 130 divides the area between the first partition 110 and the second partition 120 into a switch function compartment 102 and a wiring compartment. A second partition 140 is disposed in the wiring compartment, and is directly or indirectly connected to at least one of the first partition 110, the second partition 120, and the first partition 130. The second partition 140 is perpendicular to both the first partition 110 and the second partition 120, and divides the wiring compartment into an inlet compartment 101 and an outlet compartment 103.

[0044] The incoming line compartment 101 is used to install electrical components that connect to the power distribution bus system, the switch function compartment 102 is used to install electrical components that control and distribute the electrical energy input to the power distribution bus system, and the outgoing line compartment 103 is used to install electrical components that connect to the load lines.

[0045] The existing distribution cabinet does not have a physical separation between the incoming line compartment 101 and the outgoing line compartment 103. If the outgoing line compartment 103 fails, the generated electric arc and metal vapor will affect the adjacent incoming line compartment 101, and may even affect the entire main bus and distribution bus system.

[0046] In this embodiment, the cabinet assembly 100 includes a first partition 110, a second partition 120, a first partition 130, and a second partition 140. The second partition 120 is spaced apart on one side of the first partition 110, and the first partition 130 is disposed between the first partition 110 and the second partition 120, dividing the area between the first partition 110 and the second partition 120 into a switch function compartment 102 and a wiring compartment. The second partition 140 is disposed in the wiring compartment, dividing the wiring compartment into an inlet compartment 101 and an outlet compartment 103. In this embodiment, the second partition 140 physically isolates the inlet compartment 101 and the outlet compartment 103, reducing the impact range of a fault in the inlet compartment 101 or the outlet compartment 103.

[0047] In some embodiments, the second partition 140 is directly or indirectly connected to the first partition 110, or the second partition 140 is directly or indirectly connected to the second partition 120, or the second partition 140 is directly or indirectly connected to both the first partition 110 and the second partition 120. The second partition 140 is detachably connected to both the first partition 110 and the second partition 120.

[0048] The second partition 140 can be removed without affecting the assembly and inspection of electrical components in the inlet chamber 101 and outlet chamber 103.

[0049] In some embodiments, the cabinet assembly 100 further includes a plurality of positioning clamps 150. At least one pair of positioning clamps 150 is provided on the side of the first partition 110 near the second partition 120, or at least one pair of positioning clamps 150 is provided on the side of the second partition 120 near the first partition 110, or at least one pair of positioning clamps 150 is provided on both the side of the first partition 110 near the second partition 120 and the side of the second partition 120 near the first partition 110. That is, the connection between the second partition 140 and the first partition 110 is indirect, and the connection between the second partition 140 and the second partition 120 is also indirect.

[0050] The positioning clamp 150 includes a horizontal plate 151 and a vertical plate 152, which are vertically connected. The positioning clamp 150 can be made of metal and can be formed using sheet metal bending technology. The horizontal plate 151 is connected to the first partition 110 or the second partition 120, specifically by fastener connection, adhesive connection, welding connection, or riveting connection. To facilitate disassembly of the positioning clamp 150, the horizontal plate 151 is connected to the first partition 110 or the second partition 120 by fasteners, including screws.

[0051] The upright plate 152 is used to clamp the second partition 140. In the paired positioning clamps 150, the two upright plates 152 are located on both sides of the second partition 140. The second partition 140 is clamped between the upright plates 152 of the two positioning clamps 150. The second partition 140 and the upright plates 152 of the positioning clamps 150 can be interference-fitted to prevent the second partition 140 from moving away from or closer to the first partition 130.

[0052] The second partition 140 is clamped between the first partition 110 and the second partition 120 by the positioning clamp 150. The second partition 140 can be installed or removed in a direction away from or close to the first partition 130, thereby avoiding the second partition 140 from affecting the assembly and maintenance of electrical components in the inlet chamber 101 and the outlet chamber 103.

[0053] It should be noted that the second partition 140 is clamped between the upright plates 152 of the two positioning clamps 150. The second partition 140 and the upright plates 152 of the positioning clamps 150 can be interference-fitted, but are not limited to this. A small clearance fit can also be used between the second partition 140 and the upright plates 152 of the positioning clamps 150, depending on the specific situation. A small clearance fit can also be used between the second partition 140 and the upright plates 152 of the positioning clamps 150. The second partition 140 can be fixed by the connecting part 142 disclosed later.

[0054] In some embodiments, the second partition 140 includes a partition portion 141 and a connecting portion 142, with the connecting portion 142 perpendicularly connected to the partition portion 141. Both the partition portion 141 and the connecting portion 142 may be rectangular flat plates, and the length and width of the partition portion 141 are greater than the length and width of the connecting portion 142. The thicknesses of the partition portion 141 and the connecting portion 142 may be equal. The partition portion 141 and the connecting portion 142 may be welded or bonded together. Alternatively, the partition portion 141 and the connecting portion 142 may be integrally connected, i.e., the partition portion 141 and the connecting portion 142 may be made of the same material, and a planar structure of the partition portion 141 and the connecting portion 142, which are integrally connected, may be fabricated first, and then bent to form the perpendicularly connected partition portion 141 and the connecting portion 142.

[0055] The partition portion 141 is clamped between the upright plates 152 of multiple positioning clamps 150. A small clearance fit can also be used between the partition portion 141 and the upright plates 152 of the positioning clamps 150. The connecting portion 142 is detachably connected to either the first-layer partition 110 or the second-layer partition 120. Specifically, when the cabinet assembly 100 is installed at a higher height, the connecting portion 142 can be detachably connected to the first-layer partition 110; when the cabinet assembly 100 is installed at a lower height, the connecting portion 142 can be detachably connected to the second-layer partition 120 to facilitate the installation and removal of the second partition 140. The detachable connection between the connecting portion 142 and the first-layer partition 110 or the second-layer partition 120 can be achieved using fasteners, quick-release pins, or other methods.

[0056] The second partition 140 includes a partition portion 141 and a connecting portion 142. The partition portion 141 is clamped between a pair of positioning clamps 150, and the positioning clamps 150 can limit the left and right movement of the second partition 140. The partition portion 141 is disposed between the first partition 110 and the second partition 120, and the first partition 110 and the second partition 120 can limit the up and down movement of the second partition 140. The connecting portion 142 is detachably connected to the first partition 110 or the second partition 120, and the connecting portion 142 can limit the front and rear movement of the second partition 140.

[0057] In some embodiments, the connecting portion 142 is provided with a waist eye hole 1421, the dimension of the waist eye hole 1421 in the direction near or away from the first partition 130 is larger than the dimension of the waist eye hole 1421 in the direction near or away from the partition portion 141. The connecting portion 142 is connected to the first partition 110 or the second partition 120 through the waist eye hole 1421 by fasteners.

[0058] The connecting part 142 is provided with a waist eye hole 1421. The connecting part 142 is connected to the first partition 110 or the second partition 120 through the waist eye hole 1421. This can prevent the mounting hole of the connecting part 142 from being misaligned with the mounting hole on the first partition 110 or the second partition 120, which would make it difficult to install the second partition 140.

[0059] In some embodiments, the second partition 140 is perpendicular to the first partition 130. The second partition 140 includes a partition portion 141 and a connecting portion 142, specifically, the partition portion 141 is perpendicular to the first partition 130. The second partition 140 and the first partition 130 are spaced apart.

[0060] The second partition 140 is spaced apart from the first partition 130, providing sufficient installation space for electrical components and meeting the installation requirements of different types of switchgear. Furthermore, the connecting part 142 is provided with eyelets 1421, which connect to either the first partition 110 or the second partition 120. The eyelets 1421 allow for adjustment of the distance between the second partition 140 and the first partition 130, further satisfying the installation requirements of different types of switchgear.

[0061] In some embodiments, at least the partition portion 141 is light-transmitting, that is, the partition portion 141 is light-transmitting or the second partition 140 as a whole is light-transmitting. The partition portion 141 is light-transmitting, and the partition portion 141 or the second partition 140 as a whole may be made of transparent glass or transparent plastic material, such as polycarbonate (PC).

[0062] The partition 141 is light-transmitting or the second partition 140 as a whole is light-transmitting. The light-transmitting second partition 140 allows observation of the operating status of electrical components in the inlet chamber 101 and the outlet chamber 103.

[0063] It should be noted that the partition 141 may be made of transparent glass or transparent plastic material, but is not limited to these. The partition 141 or the second partition 140 as a whole may also be made of metal material, and the partition 141 may be designed with a hollowed-out shape so that the partition 141 can transmit light.

[0064] One or more of the first partition 110, the second partition 120, the first partition 130, and the positioning clamp 150 may be made of metal, or all of the first partition 110, the second partition 120, the first partition 130, and the positioning clamp 150 may be made of metal. Meanwhile, the first partition 110 and the second partition 120 may have a perforated design to improve the heat dissipation performance of the cabinet assembly 100.

[0065] Since one or more of the first partition 110, the second partition 120, the first partition 130, and the positioning clamp 150 can be made of metal, and the second partition 140 is also made of metal, it can improve the overall structural strength of the cabinet assembly 100, and facilitate the welding or fastening connection between the first partition 110, the second partition 120, the first partition 130, the second partition 140, and the positioning clamp 150.

[0066] In some embodiments, the second partition 140 may be made entirely of transparent plastic material. Meanwhile, the partition portion 141 is provided with a plurality of perforated holes 1411 connecting the inlet chamber 101 and the outlet chamber 103.

[0067] The second partition 140 is made of transparent plastic, providing a wider field of vision and making it easier to observe the operation of electrical components in the inlet chamber 101 and outlet chamber 103. Simultaneously, the partition 141 has multiple perforated holes 1411 connecting the inlet chamber 101 and outlet chamber 103, allowing air circulation between them. This helps to balance the temperature between the inlet chamber 101 and outlet chamber 103 and eliminate localized hot spots in the cabinet assembly 100.

[0068] In some embodiments, see Figure 3 and Figure 4 As shown, the first partition 110 and the second partition 120 have the same structure. Both the first partition 110 and the second partition 120 include a base plate 111, four side plates 112, and two top plates 113. The base plate 111 is a rectangular flat plate, and the four side plates 112 are respectively arranged around the base plate 111. The top plates 113 are connected to the side plates 112, and each of the two top plates 113 is connected to a pair of oppositely arranged side plates 112, forming a gap between the two top plates 113. Both the first partition 110 and the second partition 120 are made of metal and are formed by bending sheet metal. The connecting part 142 is connected to the top plate 113 of the first partition 110, or the connecting part 142 is connected to the base plate 111 of the second partition 120. The positioning clamp 150 is disposed on the bottom plate 111 of the first layer partition 110.

[0069] The connecting part 142 is connected to the top plate part 113 of the first layer partition 110, and a gap is formed between the partition part 141 and the bottom plate part 111, allowing air circulation between the inlet chamber 101 and the outlet chamber 103. This helps to balance the temperature between the inlet chamber 101 and the outlet chamber 103 and eliminate local hot spots in the cabinet assembly 100. In addition, since the second partition 140 is made of transparent plastic material, and a gap is formed between the partition part 141 and the bottom plate part 111, the second partition 140 is not used to support the first layer partition 110 and the second layer partition 120, which can prevent the second partition 140 from deforming and being damaged.

[0070] This application also provides a power distribution cabinet, see [link]. Figure 5As shown, the distribution cabinet includes a cabinet assembly 100 and electrical components. The cabinet assembly 100 includes an incoming line compartment 101, a switch function compartment 102, and an outgoing line compartment 103. The incoming line compartment 101 is equipped with electrical components that connect to the power distribution bus system, such as copper busbars 200. The switch function compartment 102 is equipped with electrical components that control and distribute the electrical energy input to the power distribution bus system, such as switchgear. The outgoing line compartment 103 is equipped with electrical components that connect to the load lines.

[0071] In this embodiment, the distribution cabinet includes a cabinet assembly 100, which includes a first partition 110, a second partition 120, a first partition 130, and a second partition 140. The second partition 120 is spaced apart on one side of the first partition 110, and the first partition 130 is disposed between the first partition 110 and the second partition 120, dividing the area between the first partition 110 and the second partition 120 into a switch function compartment 102 and a wiring compartment. The second partition 140 is disposed in the wiring compartment, dividing the wiring compartment into an inlet compartment 101 and an outlet compartment 103. In this embodiment, the second partition 140 physically isolates the inlet compartment 101 and the outlet compartment 103, reducing the impact range of a fault in either the inlet compartment 101 or the outlet compartment 103.
