[0002] Switchgear is an electrical device primarily used in power systems for opening, closing, controlling, and protecting electrical equipment during power generation, transmission, distribution, and energy conversion. Environmental protection cabinets are a type of switchgear. To ensure the performance of environmentally friendly gases or solid insulating materials, their structural design is more compact, with higher sealing requirements. They typically employ a fully insulated and fully enclosed structure to minimize the impact of the external environment on insulation performance. Therefore, environmental protection cabinets have higher requirements for the welding of the cabinet body. Currently, some problems exist in the welding process of environmental protection cabinets; the cabinet body is prone to deformation under high-temperature welding conditions, thus affecting the cabinet's sealing and other characteristics.

[0025] In actual operation, the cabinet body is placed on the base 1, so that the inner walls of the left side panel 10 and right side panel 20 of the cabinet body abut against the first longitudinal section 21 and the second longitudinal section 31 of the left support plate 2 and the right support plate 3, and the front and rear side panels of the cabinet body abut against the third longitudinal section 41 and the fourth longitudinal section 51 of the front support plate 4 and the rear support plate 5. Several clamps 6 are taken, and the handle 621 is rotated so that the accommodating space between one end of the body 61 and one end of the adjusting arm 62 is greater than the distance between the left and right side panels of the cabinet body. The clamps are placed outside the left and right side panels, and the handle 621 is rotated again so that the abutting part 623 abuts against the left and right side panels, thereby clamping the clamps onto the cabinet body. Then, the various side panels of the cabinet body can be welded, avoiding deformation caused by excessive heat during the welding process.
