[0048] The principle of the electrical equipment proposed in this application will be explained in detail below:

[0049] In related technologies, when the protection level of electrical equipment (such as protection level against dust, moisture or mechanical shock) meets the requirements, the internal modules (such as main power boards) do not need to be specially designed with protective structures. In this case, the large module size may cause waste of internal space of electrical equipment, increase design and manufacturing costs, and make internal wiring complex and long.

[0050] To address this technical problem, this application provides an electrical device, as described below. Figures 1-6 The electrical equipment described in the embodiments of this application.

[0051] like Figure 1 and Figure 2 As shown, the electrical equipment in this application embodiment includes: a housing 10, a mounting plate 20, a partition 30, a first main power board 41, a second main power board 42, a first device board 51, and a second device board 52.

[0052] In this embodiment, the first device board 51 and the second device board 52 can be capacitor boards in a central energy router, capacitor boards in an input-series-output-parallel medium-voltage DC converter, or capacitor boards in a flexible DC transmission system device.

[0053] The housing 10 can be made of materials such as aluminum alloy, stainless steel, fiberglass, or plastic (e.g., epoxy resin).

[0054] like Figure 2 As shown, the mounting plate 20 and the partition plate 30 are arranged intersectingly inside the housing 10, and the mounting plate 20 and the partition plate 30 form a first mounting cavity 11, a second mounting cavity 12, a third mounting cavity 13 and a fourth mounting cavity 14 between the mounting plate 20 and the cavity of the housing 10.

[0055] In this embodiment, the housing 10 has a receiving cavity, and the mounting plate 20 and the partition plate 30 are arranged perpendicularly to each other, dividing the receiving cavity into four parts, namely the first mounting cavity 11, the second mounting cavity 12, the third mounting cavity 13 and the fourth mounting cavity 14.

[0056] like Figure 2 As shown, the first mounting cavity 11 and the fourth mounting cavity 14 are located on the same side of the mounting plate 20, the first mounting cavity 11 and the second mounting cavity 12 are located on opposite sides of the mounting plate 20, the first mounting cavity 11 and the second mounting cavity 12 are located on the same side of the partition 30, and the first mounting cavity 11 and the fourth mounting cavity 14 are located on opposite sides of the partition 30.

[0057] like Figure 2 As shown, in this embodiment, the first mounting cavity 11, the second mounting cavity 12, the third mounting cavity 13, and the fourth mounting cavity 14 are arranged along a first direction r. In this embodiment, the first direction r is counterclockwise. The first mounting cavity 11 and the fourth mounting cavity 14 are located on the same side of the mounting plate 20, the second mounting cavity 12 and the third mounting cavity 13 are located on the same side of the mounting plate 20, the first mounting cavity 11 and the second mounting cavity 12 are located on opposite sides of the mounting plate 20, the third mounting cavity 13 and the fourth mounting cavity 14 are located on opposite sides of the mounting plate 20, the first mounting cavity 11 and the second mounting cavity 12 are located on the same side of the partition plate 30, the third mounting cavity 13 and the fourth mounting cavity 14 are located on the same side of the partition plate 30, the first mounting cavity 11 and the fourth mounting cavity 14 are located on opposite sides of the partition plate 30, and the second mounting cavity 12 and the third mounting cavity 13 are located on opposite sides of the partition plate 30.

[0058] like Figure 2 As shown, the first main power board 41 and the second main power board 42 are both mounted on the mounting plate 20, and the first main power board 41 and the second main power board 42 are located in the first mounting cavity 11 and the second mounting cavity 12, respectively.

[0059] The first device board 51 and the second device board 52 are both mounted on the mounting plate 20. The first device board 51 and the second device board 52 are located in the third mounting cavity 13 and the fourth mounting cavity 14, respectively.

[0060] The first main power board 41 is electrically connected to the first device board 51, and the second main power board 42 is electrically connected to the second device board 52.

[0061] In this embodiment, the first main power board 41 and the first device board 51 are mounted on the same side of the mounting plate 20, and the second main power board 42 and the second device board 52 are mounted on opposite sides of the mounting plate 20 and the first main power board 41 and the first device board 51. The first main power board 41 is electrically connected to the first device board 51, and the second main power board 42 is electrically connected to the second device board 52.

[0062] In related technologies, when the protection level of electrical equipment (such as protection against dust, moisture, or mechanical shock) meets the requirements, the internal modules (such as the main power board) do not need to be specially designed with protective structures. However, a larger module size may lead to a waste of internal space in the electrical equipment. Larger module sizes usually increase weight, resulting in poor portability, inconvenient installation and transportation, and higher costs. At the same time, it is necessary to improve the heat dissipation capacity of the heat dissipation system, which increases design and manufacturing costs. Internal wiring is also complex and lengthy, making installation more difficult.

[0063] In this embodiment, the electrical equipment has a mounting plate 20 and a partition 30 arranged in a cross pattern installed inside the housing 10, dividing the internal cavity of the housing 10 into four parts: a first mounting cavity 11, a second mounting cavity 12, a third mounting cavity 13, and a fourth mounting cavity 14. These four cavities are arranged along a first direction r. The first and fourth mounting cavities 11 and 14 are located on the same side of the mounting plate 20, while the first and second mounting cavities 12 are located on opposite sides of the mounting plate 20. The first and second mounting cavities 11 and 12 are located on the same side of the partition 30, and the first and fourth mounting cavities 14 are located on opposite sides of the partition 30. A first main power board 41 and a first device board 51 are mounted on the same side of the mounting plate 20. The second main power board 42 and the second device board 52 are mounted on the mounting plate 20 on both sides of the first main power board 41 and the first device board 51. The first main power board 41, the second main power board 42, the first device board 51 and the second device board 52 are all mounted on the same mounting plate 20, which occupies less space, reduces the use of the mounting plate 20, and reduces the cost and weight of the electrical equipment. In addition, the first main power board 41, the second main power board 42, the first device board 51 and the second device board 52 are each located in an independent mounting cavity, which has a good heat dissipation effect. The first main power board 41 is electrically connected to the first device board 51, and the second main power board 42 is electrically connected to the second device board 52. The main power board and the capacitor board on the same side of the mounting plate 20 are electrically connected, which makes the installation less difficult and the wiring design more reasonable.

[0064] According to the electrical equipment provided in the embodiments of this application, by setting the mounting plate 20 and partition plate 30 in the housing 10, the first component board and the second component board make the power board and capacitor board occupy less space, reducing the cost and weight of the electrical equipment. At the same time, the first component board and the second component board have good heat dissipation effect and reasonable wiring design.

[0065] In some embodiments, each mounting cavity may be provided with a first air vent 61 and a second air vent 62.

[0066] like Figures 1-4 As shown, the first air vent 61 is located on the wall surface opposite to the mounting plate 20 in each mounting cavity, and the second air vent 62 is located on the wall surface opposite to the partition plate 30 in each mounting cavity.

[0067] In this embodiment, the first mounting cavity 11, the second mounting cavity 12, the third mounting cavity 13 and the fourth mounting cavity 14 are all provided with a first air vent 61 on the wall surface opposite to the mounting plate 20, and the first mounting cavity 11, the second mounting cavity 12, the third mounting cavity 13 and the fourth mounting cavity 14 are all provided with a second air vent 62 on the wall surface opposite to the partition plate 30.

[0068] It is understandable that when the first air vent 61 is an air inlet, the second air vent 62 can be an air outlet; when the first air vent 61 is an air outlet, the second air vent 62 can be an air inlet.

[0069] In this embodiment, there are four first air vents 61, which correspond to the first mounting cavity 11, the second mounting cavity 12, the third mounting cavity 13 and the fourth mounting cavity 14 respectively. There are two second air vents 62, one of which corresponds to the first mounting cavity 11 and the second mounting cavity 12, and the other corresponds to the third mounting cavity 13 and the fourth mounting cavity 14.

[0070] In some embodiments, the first air vent 61 and the second air vent 62 may be provided in other quantities.

[0071] According to the electrical equipment provided in the embodiments of this application, by providing a first air vent 61 and a second air vent 62 in each mounting cavity, it is convenient to dissipate heat from the main power board and capacitor board in each mounting cavity.

[0072] In some embodiments, such as Figure 1 As shown, housing 10 may be provided with wiring terminals 70.

[0073] Terminal 70 can be a copper busbar.

[0074] The wiring terminal 70 is located on the outer wall of the housing 10 adjacent to the first air vent 61 and the second air vent 62.

[0075] In this embodiment, the wiring terminal 70 is located on the outer wall of the housing 10 adjacent to the first air vent 61 and the second air vent 62. The first main power board 41 is electrically connected to the first device board 51, and the second main power board 42 is electrically connected to the second device board 52. The first device board 51 and the second device board 52 are connected to the wiring terminal 70, and the wiring terminal 70 is used to connect to the outside world.

[0076] According to the electrical equipment provided in the embodiments of this application, by providing a wiring terminal 70 on one side of the outer wall of the housing 10, it is convenient for the main power board and capacitor board inside the housing 10 to be connected to the outside.

[0077] In some embodiments, such as Figure 2 As shown, the electrical equipment may also include: a fan assembly 80.

[0078] Each mounting cavity is equipped with a fan assembly 80.

[0079] The first air outlet 61, the fan assembly 80, and the second air outlet 62 constitute an air duct. The first main power board 41, the second main power board 42, the first device board 51, and the second device board 52 are all located in the air duct.

[0080] In this embodiment, the first main power board 41 installed in the first mounting cavity 11 is located between the fan assembly 80 and the second air outlet 62 in the first mounting cavity 11; the second main power board 42 installed in the second mounting cavity 12 is located between the fan assembly 80 and the second air outlet 62 in the second mounting cavity 12; the first device board 51 installed in the third mounting cavity 13 is located between the fan assembly 80 and the second air outlet 62 in the third mounting cavity 13; and the second device board 52 installed in the fourth mounting cavity 14 is located between the fan assembly 80 and the second air outlet 62 in the fourth mounting cavity 14, forming an airflow direction that sequentially passes through the first air outlet 61, the fan assembly 80, the main power board (or capacitor board), and the second air outlet 62.

[0081] According to the electrical equipment provided in the embodiments of this application, by providing fan assemblies 80 in each mounting cavity, it is convenient for each mounting cavity to dissipate heat independently, resulting in a better heat dissipation effect.

[0082] In some embodiments, the housing 10 may be provided with mounting holes 15.

[0083] like Figure 2 and Figure 3 As shown, mounting hole 15 is located on the outer wall of housing 10 adjacent to first air outlet 61 and second air outlet 62, and fan assembly 80 is mounted in mounting hole 15.

[0084] In this embodiment, there are four mounting holes 15. All four mounting holes 15 are located on the same outer wall of the housing 10 adjacent to the first air outlet 61 and the second air outlet 62. The four mounting holes 15 correspond to the first mounting cavity 11, the second mounting cavity 12, the third mounting cavity 13 and the fourth mounting cavity 14, respectively. The fan assembly 80 in each mounting cavity is installed in the mounting hole 15. The mounting hole 15 is located on the outer wall of the housing 10. The fan assembly 80 is not installed on the mounting plate 20, so it will not affect the main power board or the capacitor board, and at the same time saves space inside the housing 10.

[0085] In some embodiments, the number and size of the mounting holes 15 can be specifically set according to the actual situation.

[0086] According to the electrical equipment provided in the embodiments of this application, by providing mounting holes 15 on the outer wall of the housing 10 adjacent to the first air outlet 61 and the second air outlet 62, it is convenient to install the fan assembly 80, saves space, and the electrical equipment is small in size.

[0087] In some embodiments, the fan assembly 80 may include a fan 81 and a support member 82.

[0088] One end of the support member 82 is installed in the mounting hole 15, and the fan 81 is installed on the support member 82.

[0089] One end of the support member 82 can be connected to the mounting hole 15 by means of snap-fit, bolt connection, welding or adhesive.

[0090] In this embodiment, the support member 82 is installed in the mounting hole 15, and the support member 82 is located between the fan 81 and the partition 30, with the fan 81 facing the second air outlet 62.

[0091] According to the electrical equipment provided in the embodiments of this application, by setting the configuration of the fan assembly 80, it is easy to disassemble and install the fan 81. At the same time, the fan 81 is installed on the support member 82, which improves stability while ensuring heat dissipation effect.

[0092] In some embodiments, the support member 82 may include a support member body 821 and a bent portion 822.

[0093] like Figure 5 As shown, the bent portion 822 and the support body 821 have a certain angle.

[0094] like Figure 2 and Figure 5 As shown, the bent part 822 is installed in the mounting hole 15, and the fan 81 is installed in the support body 821.

[0095] In this embodiment, the bent portion 822 is perpendicular to the support body 821. The bent portion 822 is installed (e.g., snapped) in the mounting hole 15. The length direction of the support body 821 is perpendicular to the wall of the housing 10 where the mounting hole 15 is located. The fan 81 is installed on the support body 821. When the fan 81 vibrates, the vibration is transmitted to the support body 821. The bent portion 822 is installed in the mounting hole 15 and is perpendicular to the support body 821. The vibration transmitted to the bent portion 822 will be dispersed to the housing 10, which has a better vibration resistance effect and the fan assembly 80 has high stability.

[0096] According to the electrical equipment provided in the embodiments of this application, the fan assembly 80 has high stability due to the structure of the support member 82 and the assembly method with the mounting hole 15.

[0097] In some embodiments, the fan assembly 80 may have a plurality of fans 81.

[0098] like Figure 5 As shown, multiple fans 81 are spaced apart on the support member 82.

[0099] In this embodiment, each mounting cavity is provided with a fan assembly 80, and each fan assembly 80 includes four fans 81. The four fans 81 are evenly spaced on the support member 82. The first main power board 41, the second main power board 42, the first device board 51 and the second device board 52 are respectively located between the four fans 81 and the second air outlet 62 in their respective mounting cavities. The air circulation in the mounting cavity is good and the heat dissipation effect is good.

[0100] It should be noted that the dimensions and speed of the fan 81 can be set according to the actual usage.

[0101] According to the electrical equipment provided in the embodiments of this application, by setting the fan assembly 80 to have multiple fans 81, the heat dissipation effect of the fan assembly 80 is improved, ensuring the normal operation of the first main power board 41, the second main power board 42, the first device board 51 and the second device board 52.

[0102] In some embodiments, such as Figure 4 As shown, the housing 10 may include an outer shell 16, an upper cover 17, and a lower cover 18.

[0103] The upper cover plate 17 and the lower cover plate 18 are installed at opposite ends of the outer casing 16.

[0104] In this embodiment, the upper cover plate 17 and the lower cover plate 18 are detachably installed at opposite ends of the housing 16, which facilitates the installation of the main power board and the capacitor board on the mounting plate 20 or their removal from the mounting plate 20 for maintenance on the upper and lower sides of the housing 10, respectively. The operation is simple. The first air vent 61 is provided on the upper cover plate 17 and the lower cover plate 18.

[0105] In some embodiments, the housing 10 may also include only a single-sided cover.

[0106] Grooves can also be provided at opposite ends of the housing 10 for positioning and installing the upper cover plate 17 and the lower cover plate 18.

[0107] The electrical equipment provided in the embodiments of this application, by setting the housing 10 structure, facilitates the disassembly, assembly, and maintenance of the main power board and capacitor board on the mounting plate 20, making the operation simple and efficient.

[0108] In some embodiments, both the mounting plate 20 and the partition 30 may be insulating components.

[0109] Mounting plate 20 and partition plate 30 can be made of insulating materials such as ceramic, fiberglass or plastic (such as epoxy resin) to ensure the safety of electrical connection operations.

[0110] In this embodiment, the mounting plate 20 and the partition plate 30 can be made of glass fiber reinforced epoxy resin material, which has good insulation properties and mechanical strength.

[0111] It is understandable that the mounting plate 20 and the partition plate 30 may use the same insulation material or different insulation materials.

[0112] According to the embodiments of this application, the electrical equipment is provided with mounting plate 20 and partition plate 30 as insulating components, which ensures strength while improving the insulation performance and safety of the electrical equipment.
