AI Technical Summary
The existing switchgear cabinets have insufficient structural strength, weak arc resistance, low production efficiency, and are difficult to meet the sealing requirements for high protection levels.
The modular cabinet is designed using a stepped molding process. The raised section and side panel form an inner high and outer low structure. Weld marks are placed on the height gap. Combined with a pressure relief mechanism and snap-fit design, the strength and sealing of the cabinet are improved.
It improves the mechanical strength and production efficiency of the cabinet, meets the sealing requirements of high protection level, enhances the anti-arc performance, and ensures equipment safety and simplifies the production process.

Abstract
Claims
1. A split cabinet based on a stepped die process, a gas tank connected with the split cabinet, the split cabinet comprising: The front cabinet (2) and the rear cabinet (3) are characterized in that: The front cabinet (2) includes: a side panel 1 (2.1) symmetrically arranged on the left and right sides; the rear cabinet (3) includes: a bottom plate (2.2), a side panel 2 (3.1) and a partition (4). The bottom plate (2.2) has a partition (4) on one side and a side panel 2 (3.1) on the other three sides. The rear side of the side panel 1 (2.1) is connected to the partition (4). Side plate one (2.1) and side plate two (3.1) are connected to the air box through connecting structure one and connecting structure two, respectively. The connecting structures form an inner high and outer low structure through the protrusion, so that there is a height gap between the protrusion and the air box and the side plate when welding, and the weld scar is set on the height gap.
2. A split-type cabinet based on step-mold technology according to claim 1, characterized in that: The first connection structure includes a side part (10) and an upper part (13). The side plate (2.1) has a side part (10) extending inward on the rear side and an upper part (13) extending inward on the upper side. The side part (10) and the upper part (13) are integrally connected.
3. A split-type cabinet based on step-mold technology according to claim 2, characterized in that: The side part (10) is lower than the partition (4) and the front cabinet (2) and the rear cabinet (3) are fixed by screws (14). The inner side of the side part (10) is higher than the partition (4) and is bent to form a protruding part (9.1) that protrudes backward. The bent part forms a sloping step structure (12).
4. A split-type cabinet based on step-mold technology according to claim 2, characterized in that: The upper part (13) is bent to form an upward protruding protrusion (9.3) on the inner side, and a sloping step structure (12) is formed at the bend.
5. A split-type cabinet based on step-mold technology according to claim 2, characterized in that: A limiting waist-shaped groove (16) is provided on the upper side (13).
6. A split-type cabinet based on step-mold technology according to claim 1, characterized in that: The second connection structure includes: an upper part (8), the upper side of the second side plate (3.1) is provided with an upper part (8) extending inward, the inner side of the upper part (8) is bent to form an upward protruding part (9.2), and the bend forms a slope-shaped step structure (12).
7. A split-type cabinet based on step-mold technology according to claim 1, characterized in that: All protrusions are provided with multiple through holes (11), through which the air box is connected to the protrusion.
8. A split-type cabinet based on step-mold technology according to claim 1, characterized in that: The shape and position of all protrusions are adaptively matched.
9. A split-type cabinet based on step-mold technology according to claim 1, characterized in that: The partition (4) is provided with a pressure relief port (6), and a pressure relief plate (7) is provided on the pressure relief port (6).
10. A split-type cabinet based on step-mold technology according to claim 9, characterized in that: The upper end of the pressure relief plate (7) is connected with the partition plate (4) through a screw (14), and the lower end is fixed through a buckle (15). When the pressure relief plate (7) bears pressure exceeding the design limit, the buckle (15) will be deformed and tripped to release pressure.
