[0002] Electrical cabinets are core equipment in industrial automation control, mainly used for power distribution, circuit protection, and environmental control. Currently, due to inconsistent voltage platforms in different regions, electrical cabinets must be equipped with transformers. Typically, the transformer is installed outside the electrical cabinet and connected to the internal components via cables. The transformer transforms the power supply lines. The wiring between the internal components and the external transformer is complex, difficult to operate, and the exposed wiring is easily damaged. To solve this problem, integrating the transformer into the electrical cabinet is an option. However, transformers generate significant heat during operation, and high temperatures can reduce transformer power. Furthermore, the high temperature generated by the transformer can affect other nearby electrical components. Therefore, there is an urgent need to develop an electrical cabinet that is easy to connect to the transformer and can also solve the transformer's heat dissipation problem. Utility Model Content

Furthermore, baffles reduce the gap between the transformer and the cabinet's side walls, allowing cool air to circulate around the transformer, significantly improving heat dissipation. Additionally, the transformer compartment is divided into low-temperature and high-temperature zones, allowing for the rational arrangement of components based on their temperature resistance and operating temperature requirements within these two areas, resulting in a more efficient and efficient system.

Of course, this is not the only option; the inlet and outlet leads can also be placed in other areas as needed.

[0028] In addition, the transformer compartment, the combiner compartment, and the auxiliary power compartment are arranged sequentially from top to bottom along the height of the cabinet and are all separated by partitions. The heat dissipation ducts of the three compartments are set independently and do not affect each other, which helps to improve the heat dissipation effect. Attached Figure Description

[0037] The following reference Figures 1 to 7 This application describes an electrical cabinet according to some embodiments.

[0038] See Figures 1 to 7 As shown, an embodiment of this application provides an electrical cabinet, including: a cabinet body 1, a transformer 2, a first air supply component 3, and a baffle 4; wherein, the cabinet body 1 forms a transformer compartment 101, and the transformer 2 is installed in the transformer compartment 101; the baffle 4 is disposed in the transformer compartment 101 and extends toward the transformer 2, indicating that there is a gap between the cabinet body 1 and the transformer 2, so as to ensure that there is no interference during forklift installation. When the transformer 2 is installed in place, the baffle 4 is located on the side of the transformer 2, and an air duct opening 11 is formed between the baffle 4 and the transformer 2; The transformer compartment 101 has a first air inlet 106 and a first air outlet that are connected to the outside. The first air inlet 106 and the first air outlet are respectively located on both sides of the baffle 4. The first air conveying component 3 is located in the cabinet 1. The first air conveying component 3 can drive air through the first air inlet 106 into the transformer compartment 101, flow through the air duct 11, and finally be discharged from the first air outlet to dissipate heat from the transformer 2.

[0039] As can be seen from the structure described above, the electrical cabinet provided in this application has a transformer compartment 101 inside for installing the transformer 2, that is, the transformer 2 is integrated into the cabinet body 1 of the electrical cabinet. This facilitates the wiring operation between the transformer 2 and other electrical components in the electrical cabinet, saving time and effort. Furthermore, the transformer compartment 101 is equipped with air inlets and outlets and a fan, which can cool the transformer 2 inside the transformer compartment 101, thus playing a role in heat dissipation of the transformer 2, ensuring the working power of the transformer 2, and not affecting other nearby electrical components. Moreover, the baffle 4 is used to reduce the gap between the transformer 2 and the side wall of the cabinet body 1, allowing cold air to circulate from the vicinity of the transformer 2, which greatly improves the heat dissipation effect of the transformer 2. In addition, the transformer compartment 101 is divided into a low temperature zone 1011 and a high temperature zone 1012 by the transformer 2, so that the temperature resistance and working temperature requirements of the components can be reasonably arranged in the two zones according to actual needs, which is more reasonable.

[0040] Furthermore, preferably, the first air supply component 3 is installed inside the cabinet 1. The cabinet 1 can also protect the first air supply component 3, and play a role in dustproofing and waterproofing, which helps to extend the service life of the first air supply component 3. Of course, it is not limited to this. The first air supply component 3 can also be installed outside the cabinet 1, depending on the actual needs.

[0041] In this embodiment, preferably, as follows: Figure 4 As shown, along the first preset direction a, the transformer 2 divides the transformer compartment 101 and the baffle 4 into a low-temperature zone 1011 and a high-temperature zone 1012. The first air inlet 106 is located on the side of the cabinet 1 corresponding to the low-temperature zone 1011. The first air outlet and the first air conveying component 3 are located on the side of the cabinet 1 corresponding to the high-temperature zone. The first air conveying component 3 can drive the air to enter the low-temperature zone 1011 through the first air inlet 106, and enter the high-temperature zone 1012 through the air duct 11, and finally exit the cabinet through the first air outlet.

[0042] As can be seen from the structure described above, the first air supply component 3 can drive air through the first air inlet 106 into the low temperature zone 1011, and through the air duct 11 into the high temperature zone 1012, and finally out of the cabinet through the first air outlet, thereby accelerating the heat dissipation of the transformer 2 and improving the heat dissipation effect. Moreover, the low temperature zone 1011 and the high temperature zone 1012 are distributed in an orderly manner, which makes it convenient to install other electrical components according to temperature requirements.

[0043] Furthermore, preferably, the first preset direction a is the front-to-back direction of the cabinet 1. Of course, it is not limited to this. The first preset direction a can also be the left-to-right direction of the cabinet 1, etc., depending on the actual needs. Furthermore, preferably, the first air supply component 3 is located in the high-temperature zone 1012, and the first air inlet 106, the first air supply component 3, and the first air outlet are correspondingly arranged along the first preset direction a. This linear arrangement of the air duct provides better heat dissipation for the transformer 2. Of course, this is not the only option; other layouts can also be used. For example, the first air inlet 106 can be located on the left or right side of the cabinet 1, and the second air inlet 107 can also be located on the left or right side of the cabinet 1, depending on the actual needs.

[0044] Furthermore, preferably, the first air supply component 3 is a fan. Of course, it is not limited to this and can also be other types of equipment such as an external air conditioner.

[0045] In this embodiment, preferably, as follows: Figure 6 and Figure 7 As shown, the transformer 2 includes multiple iron core coil assemblies 21, and the multiple iron core coil assemblies 21 are arranged sequentially along a direction perpendicular to the first preset direction a, and an air duct is formed between any two adjacent iron core coil assemblies 21 along the first preset direction a. As can be seen from the structure described above, air ducts are set in two adjacent iron core coil assemblies 21 to ensure heat dissipation for each iron core coil assembly 21. Moreover, preferably, the first air inlet 106, air duct, first air conveying component 3 and first air outlet are arranged sequentially along the first preset direction a to ensure a straight heat dissipation channel, which further helps to improve the heat dissipation effect.

[0046] In this embodiment, preferably, as follows: Figure 1 As shown, the transformer compartment 101 is located at the bottom of the cabinet 1 along its height direction. As can be seen from the structure described above, transformer 2 is relatively heavy, therefore it is placed at the bottom to ensure a low center of gravity and safe transportation. Of course, this is not the only option; the transformer compartment 101 can also be located in other positions within the cabinet 1, depending on the specific needs. In this embodiment, preferably, as follows: Figure 1 As shown, the cabinet 1 has a busbar compartment 102, and along the height direction of the cabinet 1, the busbar compartment 102 is located above the transformer compartment 101, and a first partition 104 is provided between the busbar compartment 102 and the transformer compartment 101 to separate the busbar compartment 102 from the transformer compartment 101; the electrical cabinet also includes a busbar module 9, and the busbar module 9 is installed in the busbar compartment 102. As can be seen from the structure described above, a junction box 102 is set above the transformer compartment 101, and is separated from the transformer compartment 101 below by a first partition 104 to avoid mutual interference between the two compartments. In particular, the two compartments can dissipate heat independently, which helps to ensure the heat dissipation effect of each compartment. In this embodiment, preferably, as follows: Figure 1 and Figure 3 As shown, the electrical cabinet also includes an inlet lead 5 and an outlet lead 6 connected to the bus module 9, and both the inlet lead 5 and the outlet lead 6 are located in the low-temperature zone 1011. As can be seen from the structure described above, placing the inlet lead 5 and the outlet lead 6 in the low-temperature zone 1011 at the front of the transformer 2 can effectively prevent the inlet lead 5 and the outlet lead 6 from experiencing high-temperature derating. Of course, this is not the only option; the inlet lead 5 and the outlet lead 6 can also be placed in other areas as needed. In this embodiment, preferably, as follows: Figure 1 As shown, the electrical cabinet also includes a first busbar, a first partition 104 having a first clearance notch, a portion of the first busbar extending through the first clearance notch into the manifold 102 and connected to the manifold module 9, and another portion of the first busbar extending through the first clearance notch into the low-temperature zone 1011 and connected to the inlet lead 5.

[0047] Based on the structure described above, it can be seen that the busbar through-cabin structure is more convenient for field wiring compared to the wire harness through-cabin structure.

[0048] In this embodiment, preferably, as follows: Figure 1 As shown, the electrical cabinet also includes a second busbar 7. The first partition 104 has a second clearance notch. A portion of the second busbar 7 extends into the manifold 102 via the second clearance notch and is connected to the manifold module 9. Another portion of the second busbar 7 extends into the low-temperature zone 1011 via the second clearance notch and is connected to the outflow lead 6. Based on the structure described above, it can be seen that the busbar through-cabin structure is more convenient for field wiring compared to the wire harness through-cabin structure.

[0049] In this embodiment, preferably, as follows: Figure 1 As shown, along the first preset direction a, a second air inlet 107 is formed on one side of the cabinet 1 corresponding to the manifold 102, and a second air outlet and a second air conveying component 8 are provided on the other side of the cabinet 1 corresponding to the manifold 102. The second air conveying component 8 can drive air to enter the manifold 102 through the second air inlet 107 and be discharged through the second air outlet. As can be seen from the structure described above, the combiner compartment 102 is equipped with a heat dissipation duct, which can dissipate heat from the combiner module 9 and ensure the normal operation of the combiner module 9. Moreover, the combiner compartment 102 is equipped with an independent heat dissipation duct, which is independent from the heat dissipation duct of the transformer compartment 101. The upper and lower heat dissipation ducts will not interfere with each other, thus ensuring the heat dissipation effect.

[0050] Furthermore, preferably, the second air supply component 8 is disposed within the manifold 102, and the second air inlet 107, the second air supply component 8, and the second air outlet are correspondingly disposed along the first preset direction a. Of course, this is not the only option; the positions of the aforementioned structures can be designed according to actual needs. Furthermore, preferably, the second air supply component 8 is a fan. Of course, it is not limited to this and can also be other types of equipment such as an external air conditioner.

[0051] In this embodiment, preferably, as follows: Figure 1 As shown, the cabinet 1 has an auxiliary power compartment 103, which is located above the combiner compartment 102 along the height direction of the cabinet 1. A second partition 105 is provided between the auxiliary power compartment 103 and the combiner compartment 102 to separate the auxiliary power compartment 103 from the combiner compartment 102. The electrical cabinet also includes an auxiliary power module 10, which is installed in the auxiliary power compartment 103. Preferably, the auxiliary power module 10 includes components such as a miniature circuit breaker, a switching power supply, a UPS, and an EMS to comprehensively control the combiner cabinet and multiple battery cabinets. As can be seen from the structure described above, an auxiliary power compartment 103 is set above the manifold 102, and is separated from the auxiliary power compartment 103 below by a second partition 105 to avoid mutual interference between the two compartments. In particular, the two compartments can dissipate heat independently, which helps to ensure the heat dissipation effect of each compartment.

[0052] In addition, along the height of cabinet 1, auxiliary power compartment 103, combiner compartment 102 and transformer compartment 101 are arranged sequentially from top to bottom. It can be seen that combiner compartment 102 is located in the middle position. Combiner module 9 needs to be connected to a lot of large wire harnesses on site. Since the middle area has a large wiring space and the wiring height is suitable, it is easy to operate on site. It should be noted that the second partition 105 can also be provided with some clearance gaps to facilitate the wiring, etc. In addition, it should also be noted that the position of the auxiliary power compartment 103 can be set according to actual needs.

[0053] In this embodiment, preferably, as follows: Figure 1 As shown, along the first preset direction a, a third air inlet 108 is formed on one side of the cabinet 1 corresponding to the auxiliary power compartment 103, and a third air outlet is provided on the other side of the cabinet 1 corresponding to the auxiliary power compartment 103. Air can enter the auxiliary power compartment 103 through the third air inlet 108 and be discharged through the third air outlet.

[0054] As can be seen from the structure described above, the auxiliary power compartment 103 is equipped with a heat dissipation duct, which can dissipate heat from the electrical components inside the compartment, ensuring the normal operation of the electrical components inside the compartment. Moreover, the auxiliary power compartment 103 is equipped with an independent heat dissipation duct, which is independent from the heat dissipation duct of the manifold 102. The upper and lower heat dissipation ducts will not interfere with each other, ensuring the heat dissipation effect.

[0055] Furthermore, preferably, the third air supply component is disposed within the auxiliary power compartment 103, and the third air inlet 108, the third air supply component, and the third air outlet are correspondingly disposed along the first preset direction a. Of course, this is not the only option; the positions of the aforementioned structures can be designed according to actual needs.

[0056] Furthermore, preferably, the third air supply component is a fan, but of course, it is not limited to this and can also be other types of equipment such as an external air conditioner.

[0057] In this embodiment, preferably, as follows: Figure 4 and Figure 5 As shown, the baffle 4 is connected to the inner wall of the cabinet 1. As can be seen from the structure described above, when the baffle 4 is fixed to the inner wall of the cabinet 1, the cabinet 1 provides support for the baffle 4, making the baffle 4 more stable.

[0058] Furthermore, preferably, the baffle 4 and the inner wall of the cabinet 1 can be connected by welding or bolts, etc. In this embodiment, preferably, as follows: Figure 5 and Figure 7 As shown, the baffle 4 is set perpendicular to the first preset direction a, so that the air duct opening 11 is along the first preset direction a, which can quickly ventilate and cool the air. Of course, the baffle 4 can also be set at an obtuse angle or an acute angle with the first preset direction a, depending on the actual needs.

[0059] In this embodiment, preferably, as follows: Figure 5 and Figure 7 As shown, the baffle 4 includes multiple baffles 4, and the multiple baffles 4 are respectively arranged around the outer periphery of the transformer 2 along its height direction. As can be seen from the structure described above, setting multiple baffles 4 makes it easier to process, manufacture and install, and also allows them to avoid interference with other components.

[0060] Furthermore, preferably, the baffle 4 includes a left baffle 41, a right baffle 42, an upper baffle 43, and a lower baffle 44; wherein the left baffle 41 and the right baffle 42 are fixed on the left and right sides of the cabinet 1, respectively, the upper baffle 43 is fixed on the first partition 104 at the top of the transformer compartment 101, and the lower baffle 44 is fixed on the bottom wall of the cabinet 1.

[0061] Furthermore, preferably, the bottom of the transformer 2 is provided with a base, and the base forms a clearance groove that runs through its bottom and on opposite sides along the first preset direction a, so as to ensure that the forklift installation is free from interference. Furthermore, preferably, when the transformer 2 is installed in place, the lower baffle 44 provided on the bottom wall of the cabinet 1 is located in this clearance groove. In this embodiment, preferably, the electrical cabinet further includes a temperature sensor (not shown in the figure), which is located in the high-temperature zone 1012 of the transformer compartment 101 and along the first preset direction a, close to the transformer 2; the number of the first air supply components 3 is multiple, and preferably four, which will be used as an example for explanation later. Of course, it is not limited to this, and the number of the first air supply components 3 may be less than four or more than four, etc., depending on the actual needs.

[0062] As can be seen from the structure described above, the temperature sensor collects the outlet temperature of transformer 2, and when the temperature reaches the set value T1, one fan is turned on; when the temperature reaches T2, two fans are turned on; when the temperature reaches T3, three fans are turned on; and when the temperature reaches T4, four fans are turned on, which can reduce fan energy consumption and improve system efficiency. In this embodiment, preferably, as follows: Figure 1 As shown, the front panel of the cabinet 1 has three notches arranged sequentially from top to bottom, and each notch is fitted with a louver. These three louvers are the aforementioned first air inlet 106, second air inlet 107, and third air inlet 108, respectively.

[0063] In this embodiment, preferably, as follows: Figure 1 As shown, along the first preset direction a, cabinet 1 has openable or closable doors 109 on opposite sides, facilitating the installation of various electrical components in the three compartments and enabling subsequent opening and maintenance. However, this is not the only option; the cabinet doors 109 on opposite sides of cabinet 1 may also be closed, depending on actual needs.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
