The integrated cabinet 1, one low-voltage cabinet 3 and several high-voltage cabinets 4 are arranged in sequence to form a first row, and the control cabinet 2, one low-voltage cabinet 3 and several high-voltage cabinets 4 are arranged in sequence to form a second row. A channel 5 is formed between the first row and the second row. The same number of high-voltage cabinets 4 are arranged opposite to each other on both sides of the channel 5. The integrated cabinet 1 and the control cabinet 2 are arranged opposite to each other on both sides of the channel 5. The output ends of the low-voltage cabinets 3 and several high-voltage cabinets 4 in each row are electrically connected in series in sequence, and the output end of the last high-voltage cabinet 4 in the two rows is output through the integrated cabinet 1. For example Figure 1 , Figure 6As shown, in the row on the upper right side, one output end of the low-voltage cabinet 3 is directly connected to the integrated cabinet 1 via the busbar, one output end is connected in series with one output end (busbar) of the adjacent high-voltage cabinet 4, and the other output end (busbar) is connected to one output end (busbar) of another adjacent high-voltage cabinet 4, and the other output end (busbar) is connected to one output end (busbar) of another adjacent high-voltage cabinet 4. The output ends of each high-voltage cabinet 4 are connected in series in sequence, and the other output end of the last high-voltage cabinet 4 is connected to the integrated cabinet 4 via the busbar. Similarly, in the row on the lower left side, the other output end of the low-voltage cabinet 3 is connected to the integrated cabinet 4 via the busbar across the second-floor aisle 9, and the other output end (busbar) of the last high-voltage cabinet 4 is also connected to the integrated cabinet 4 via the busbar across the second-floor aisle 9, and finally the integrated cabinet 4 output is connected to the load to supply power.

[0029] A high-power pulse power supply system of this embodiment, the high-voltage cabinet 4 is the high-voltage power unit that constitutes the high-power pulse power supply system, the low-voltage cabinet 3 is the low-voltage power unit, the control cabinet 2 is the control unit, and the integrated cabinet 1 is the output confluence unit. Each unit is separately formed and arranged in the structural form of an electrical cabinet, and the high-voltage cabinets 4 located on both sides of the channel 5 are symmetrically arranged in the structural layout, the adjacent high-voltage cabinets 4 in the same row are close to and electrically connected, and the low-voltage cabinet 3 and the high-voltage cabinet 4 are both controlled by the control cabinet 2.

[0030] A high-power pulse power supply system of this embodiment is designed from the aspects of safety, reliability, operation and maintenance, installation and debugging of the power supply system. It adopts a universal module design, combines various electrical cabinets in a building block manner to form a complete set of double-row power supply systems. The positions and layouts of various electrical cabinets are reasonable, which can effectively reduce the footprint of the power supply system and the amount of busbars used. In addition, staff can also enter channel 5 for maintenance.

[0031] Preferably, this embodiment adopts 12 high-voltage cabinets 4, 2 low-voltage cabinets 3, and 1 control cabinet 2. Six high-voltage cabinets 4 are placed side by side as a group, and the low-voltage cabinets 3 are arranged on the same side of two rows of high-voltage cabinets 4 to form the high-power pulse power supply system. The vacant area is supplemented with an integrated cabinet 1, which is used as the output convergence unit of the power supply, corresponding to the control cabinet 2, and a corridor channel 5 is formed between the first row and the second row.

[0032] It can be understood that the number of high-voltage cabinets 4 can be adaptively adjusted according to the power demand of the power supply system, and the width of the channel 5 can be adaptively adjusted according to the demand.

[0033] In this embodiment, the side of each electrical cabinet away from the channel 5 is preferably set as the front, and the side close to the channel 5 is set as the back. The electrical cabinets in the two rows are structurally and electrically symmetrical relative to the channel 5. On the basis of realizing the structural advantages of the power supply system, the probability of staff entering the channel 5 is reduced, which is conducive to further improving the safety of the power supply system.

[0034] Example 2 like Figure 1 As shown, in a high-power pulse power supply system of this embodiment, on the basis of embodiment 1, the structural dimensions of the combination of the integrated cabinet 1 and the low-voltage cabinet 3, the structural dimensions of the combination of the control cabinet 2 and the low-voltage cabinet 3, and the dimensions of the high-voltage cabinet 4 are all the same. The use of cabinets of the same size can facilitate procurement, production, packaging, etc., while improving the overall aesthetics. In actual use, the size of each cabinet can be adjusted according to needs.

[0035] A high-power pulse power supply system of the present embodiment, the structure of the combination of the integrated cabinet 1 and the low-voltage cabinet 3, the structure of the combination of the control cabinet 2 and the low-voltage cabinet 3 are arranged relatively on both sides of the channel 5, and the two parts are set to the same size, which is conducive to ensuring the regular appearance of the formed power supply system, and further set it to the same size as the high-voltage cabinet 4 to form an integrated layout structure, which is convenient for splicing the various power unit cabinets into a whole.

[0036] It can be understood that the integrated cabinet 1 and the low-voltage cabinet 3, the control cabinet 2 and the low-voltage cabinet 3 can be a combination of two independent electrical cabinets, or a single electrical cabinet with a two-part installation space formed by setting a block.

[0037] In this embodiment, it is preferred to use an integrated cabinet 1 and a low-voltage cabinet 3, and the control cabinet 2 and the low-voltage cabinet 3 are respectively structures of two parts of installation space formed by blocking, and their combined structure has the same structural size as the high-voltage cabinet 4, so that the integrated cabinet 1 and the low-voltage cabinet 3, the control cabinet 2 and the low-voltage cabinet 3 are prepared as a whole, and after splicing, it can be ensured that the first row and the second row have the same structural size, further reducing the difficulty of forming the power supply system.

[0038] Example 3 like Figure 1 , Figure 6 As shown, a high-power pulse power supply system of this embodiment is based on embodiment 1 or embodiment 2, and end members 6 are set at both ends of the channel 5 to connect the ends of the first row and the second row, and the end members 6 are set with door leaves 61 for entry and exit corresponding to the channel 5, and the end members 8 are connected to the top member 7, and the top member 7 connects the tops of the first row and the second row.

[0039] In a high-power pulse power supply system of the present embodiment, the end components 6 are cabinet components arranged at the longitudinal ends of the channel 5, and are provided with door leaves 61 that can be opened and closed. The top component 7 is arranged on the top of the first row and the second row, and the end components 6 are connected to form a cabinet component that connects the first row and the second row to form an integrated power supply system. The channel 5 is closed during the operation of the power supply system through the door leaves 61, so as to prevent unrelated personnel from entering the channel 5 during the operation of the power supply, thereby preventing accidental injuries to other personnel during the operation of the power supply system.

[0041] A high-power pulse power supply system in this embodiment adopts two cabinet units 8 stacked up and down to form each electrical cabinet, which breaks down each electrical cabinet into parts, reduces the difficulty of preparing each electrical cabinet, further facilitates the operation, assembly and maintenance of the power supply system, and improves its convenience and reliability.

[0042] As a preferred solution, the frame component 81 that constitutes the cabinet unit 8 includes a combination of a cabinet frame and a mounting frame for installing and fixing internal module devices.

The cover component 82 preferably adopts a cover plus a snap lock structure for easy disassembly, and considers grounding to ensure electrical safety.

[0043] It can be understood that the volume of each cabinet unit 8 can be adjusted according to actual conditions such as preparation cost, lifting cost, production conditions, etc. When the load-bearing capacity is large, special consideration is required for the frame and columns of the cabinet unit 8 to determine the material and connection structure to ensure the overall strength of each electrical cabinet, so as to achieve independent and stable fixation and mutual connection of each module in each electrical cabinet, improve the compactness of the pulse power supply structure, and facilitate structural loading and unloading. In order to improve the overall strength of the structure, the base support can also be strengthened by component molding at the bottom of the cabinet unit 8 at the bottom layer.

[0044] As another preferred solution, in order to further facilitate the installation of the cabinet units 8, the cabinet units 8 stacked up and down have reserved a sufficient number of detachable lifting ring mounting holes, which can be removed after the on-site installation is completed, so as to facilitate the lifting and splicing of each electrical cabinet. After the splicing of the cabinet units 8 stacked up and down is completed, the connection parts are tightened to form the entire electrical cabinet.
