[0055] It should be understood that the terms "upper", "lower", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0056] The terms "first" and "second" are used for descriptive purposes only and are not intended to imply relative importance.

[0057] The utility model provides a power supply cabinet that can be used to power products such as CT scanners. It includes a cabinet body 1, a device mounting plate, electronic components, and a transformer unit. The power supply cabinet body 1 is vertical, allowing the transformer and all components to be arranged within the height range of the cabinet body 1.

[0058] The power supply cabinet includes a first device mounting plate 2, which is installed inside the cabinet 1 along the height direction of the cabinet 1, that is, vertically installed inside the 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 components are arranged and installed in the first side mounting area, the central mounting area and the second side mounting area respectively, and the transformer is arranged below the first device mounting plate 2.

[0059] 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.

[0060] Figures 1 to 3 This is the first implementation diagram of the power cabinet structure. Figures 4 and 5 This is a schematic diagram of the second embodiment of the power cabinet structure.

[0061] In some embodiments of the present invention, from the bottom to the top of the cabinet 1, the first side mounting area is provided with: a power input connector 4, a contactor 5, and a main circuit breaker 6. Furthermore, a magnetic ring 18 may be optionally provided between the main circuit breaker 6 and the contactor 5.

[0062] In some embodiments of the present invention, the second side installation area is provided with: an interface panel 7 , a first filter 8 , and a second filter 9 .

[0063] In some embodiments of the present invention, 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 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 terminal block assembly 16 are arranged in parallel in a row;

[0064] The output contactor 13 and the terminal block assembly 16 are arranged at one end close to the top of the cabinet 1;

[0065] 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.

[0066] 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.

[0067] 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 cabinet 1 are precisely limited, the arrangement order of the components is not convenient to adjust.

[0068] To facilitate wiring, the structure of the device mounting plate may be designed differently without affecting the volume of the cabinet 1 .

[0069] The first device mounting board 2 has a structural reference Figure 1 and Figure 2 In this embodiment, a first component mounting board 2 is provided inside the cabinet 1, and all components except the transformer are mounted on this component mounting board.

[0070] The structure of the second device mounting board 3 is referenced Figure 3 and Figure 4 In this embodiment, in addition to the first device mounting board 2, a second device mounting board 3 is also included. Except for the transformer, all devices are mounted on these two device mounting boards.

[0071] The second component mounting plate 3 is installed inside the cabinet 1, spaced apart from the first component mounting plate along the height direction of the cabinet 1, with the second mounting plate located on the side near the top of the cabinet 1. The first miniature circuit breaker assembly 10, relay 11, and second miniature circuit breaker assembly 12 are mounted on the first component mounting plate 2, and the output contactor and terminal block assembly 5 are mounted on the second component mounting plate 3. The second filter 9 is also mounted on the second component mounting plate 3, located on the back side of the second component mounting plate 3.

[0072] There are also differences in the structures of the cabinets corresponding to these two implementation structures. If only one first device mounting plate 2 is included, the top of the back of the cabinet is inclined. If the first device mounting plate 2 and the second device mounting plate 3 are included, the top of the back of the cabinet is stepped, which is more convenient for the installation of the second filter 9.

[0073] In this structure, the installation area of the second device mounting board 3 can also be regarded as the middle installation area. The gap between the first device mounting board 2 and the second device mounting board 3 is used for wiring, and the use of two mounting boards facilitates wiring.

[0074] In order to ensure that all components can be installed and facilitate the installation of the transformer while maintaining the height of the cabinet 1, some embodiments of the present invention further design a structure of a first component mounting plate 2. The first component mounting plate 2 includes a main panel 201, and a first side panel 202 and a second side panel 203 integrally formed 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 upwardly along the bottom of the first side panel 202, and the electronic components in the second side mounting area are arranged and installed upwardly along the bottom of the second side panel 203.

[0075] 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.

[0076] The transformer unit includes an isolation transformer 14 , which is installed in a gap area between the first side panel 202 and the second side panel 203 .

[0077] Furthermore, the isolation transformer 14 can be installed inside the cabinet 1 or outside the cabinet 1 .

[0078] If installed inside the cabinet 1, the isolation transformer 14 is directly installed on the bottom plate 101 of the cabinet 1; if installed outside the cabinet 1, the isolation transformer 14 is set outside the box, and an opening is set on the bottom plate of the cabinet 1. The isolation transformer 14 can pass through the opening and be installed in combination with the power cabinet.

[0079] refer to Figure 6 and Figure 7 In some embodiments of the present invention, the transformer unit includes a control transformer 15, which is mounted on the bottom plate of the cabinet 1. Since the control transformer 15 is smaller than the isolation transformer 14 and occupies less space, the structure of the first component mounting plate 2 can be further designed to accommodate the installation of the isolation transformer 14. The length of the second side panel 203 can be made shorter than the length of the first side panel 202. After the first component mounting plate is mounted to the cabinet 1, the first side panel 202 is directly mounted to the bottom of the cabinet 1, leaving a gap between the second side panel 203 and the bottom of the cabinet 1. The control transformer 15 is mounted below the second side panel.

[0080] Along the edge of the first device mounting plate 2, a protruding rib 204 is provided toward the back of the first device mounting plate. Part of the protruding rib 204 is assembled with the back plate of the cabinet 1. The gap between the first device mounting plate and the back plate of the cabinet 1 is used for wiring.

[0081] It should be noted that, in order to control the structural properties of the structure, according to the working relationship between the various components, in the above-mentioned implementation structure, the power input connector 4, the contactor 5, and the main circuit breaker 6 are installed on one side of the first side panel 202, the interface panel 7 and the first filter 8 are installed on one side of the second side panel 203, and the second filter 9 can be installed on the first device mounting board 2 or behind the second device mounting board 3 according to the structural requirements of the device mounting board.

[0082] In order to facilitate wiring, wiring holes 102 can be designed at the top, side, bottom and other positions of the cabinet 1 according to wiring requirements, which will not be described in detail.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
