At the same time, the split design allows each cabinet to be maintained and upgraded independently, reducing safety risks. The split structure also facilitates the selection of the installation location of each cabinet according to the actual space layout, improving space utilization.

[0068] In order to install electrical components inside the first cabinet, in some embodiments of the present invention, a first component mounting plate 2 is provided in the first cabinet.

[0069] The first device mounting plate 2 is installed inside the first cabinet 1; the first device mounting plate 2 includes a central mounting area and a first side mounting area and a second side mounting area located on both sides of the central mounting area. The electronic devices installed in the first cabinet 1 are arranged and installed in the first side mounting area, the central mounting area and the second side mounting area respectively.

[0070] Components in the first and second side mounting areas are arranged vertically from bottom to top, with the components on each side positioned vertically. These components are primarily used to mount smaller components, while the central mounting area is primarily used to mount wider components. Because the central mounting area is wider than the first and second side mounting areas, some smaller components can be arranged in rows, resulting in multiple rows of components.

[0071] In some embodiments of the present invention, as shown in the attached Figure 2 As shown, from the bottom to the top of the first cabinet 1 , the first side installation area is provided with: a power input connector 21 , a contactor 5 and a main circuit breaker 6 .

[0072] In some embodiments of the present invention, as shown in the attached Figure 2 As shown, the second side installation area is provided with: an interface panel 7, a first filter 8, and a second filter 9.

[0073] In some embodiments of the present invention, as shown in the attached Figure 2 As shown, the middle installation area is provided with: a first miniature circuit breaker assembly 10, a relay 11, a second miniature circuit breaker assembly 12, an output contactor 13 and a first terminal block assembly 16, wherein the first miniature circuit breaker assembly 10 and the relay 11 are arranged in parallel in a row, and the output contactor 13 and the first terminal block assembly 16 are arranged in parallel in a row;

[0074] The output contactor 13 and the first terminal block assembly 16 are arranged at one end close to the top of the cabinet;

[0075] The first miniature circuit breaker assembly 10 and the relay 11 are arranged at one end close to the bottom of the cabinet, or the second miniature circuit breaker assembly 12 is arranged at one end close to the bottom of the cabinet.

[0076] In the above structure, there is no specific limitation on the directions of the first side mounting area and the second side mounting area, that is, the first side mounting area can be located on the left or right side of the middle mounting area.

[0077] In the above structure, the arrangement of components is rationally planned, taking into account the wiring sequence between components, as well as the volume, aspect ratio, and other characteristics of the components themselves. In some specific implementations, for example, when the length and width dimensions of the first cabinet 1 are precisely limited, the arrangement order of the components is not convenient to adjust.

[0078] In order to ensure that all electronic devices installed in the first cabinet 1 can be installed, in some embodiments of the present invention, as shown in the attached Figure 3As shown, the first device mounting plate 2 includes a main panel 201, and a first side panel 202 and a second side panel 203 integrally arranged with the main panel 201. The first side panel 202 and the second side panel 203 are spaced apart to form a gap area; the electronic components in the first side mounting area are arranged and installed upward along the bottom of the first side panel 202, and the electronic components in the second side mounting area are arranged and installed upward along the bottom of the second side panel 203.

[0079] The first side panel 202 and the second side panel 203 may have the same width, or may be designed according to the width of the product to be installed.

[0080] In order to realize the power supply function of the first cabinet and ensure that all devices can be installed and the height of the first cabinet 1 is maintained, and the installation of the transformer is also facilitated, in some embodiments of the present invention, the first cabinet also includes a first control transformer 15 and an isolation transformer 14. The first control transformer 15 and the isolation transformer 14 are both installed on the bottom plate of the first cabinet 1, and the isolation transformer 14 is located in the gap area between the first side panel 202 and the second side panel 203.

[0081] In order to realize the installation of the isolation transformer 14, in some embodiments of the present invention, as shown in the attached Figure 4 As shown, the length of the second side panel 203 is shorter than that of the first side panel 202 , and the first control transformer 15 is located below the second side panel 203 .

[0082] In some embodiments of the present invention, as shown in the attached Figure 4 As shown, the second cabinet further includes a second device mounting plate 17 and a second control transformer.

[0083] The second device mounting plate 17 is mounted on the outer wall of the second cabinet 3. The electronic devices mounted on the second cabinet 3 also include a second terminal block assembly 18 and a third miniature circuit breaker assembly 19. The electronic devices mounted on the second cabinet 3 are arranged and mounted on the second device mounting plate 17.

[0084] The second control transformer is installed inside the second cabinet 3, which is not shown in the figure.

[0085] Separating the second control transformer from the other electronic components reduces mutual electromagnetic interference and improves the electromagnetic compatibility of the second cabinet. Furthermore, since the transformer generates heat during operation, installing it inside the second cabinet 3 and the other electronic components outside of it effectively isolates the heat source and reduces thermal interference. Installing the other electronic components outside the second cabinet 3 also facilitates user access. Maintenance personnel do not need to open the second cabinet 3 to perform maintenance or replace electronic components, saving maintenance time and reducing maintenance costs.

[0086] In order to improve the safety of the second cabinet and prevent accidental touching or damage to the electronic components, in some embodiments of the present invention, as shown in the attached Figure 5 As shown, a shield 20 is provided outside the electronic device installed in the second cabinet 3 , and the shield 20 is connected to the second cabinet 3 and / or the second device mounting plate 17 to at least partially shield the electronic device installed in the second cabinet 3 .

[0087] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0088] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
