AI Technical Summary
The back cover of the existing switch cabinet has low strength and is easily deformed by high-temperature and high-pressure gas after a short circuit in the busbar chamber, affecting the use of the cabinet.
A high-strength rear cover plate of the switch cabinet is designed. By installing a reinforcement plate on the rear cover plate body and bending multiple vertical corrugated protrusions on the reinforcement plate, the corrugated protrusions face the inside of the switch cabinet, forming an air duct to improve heat dissipation performance, and connecting it with the rear cover plate through welding to improve impact resistance.
By strengthening the design of the plate and corrugated projections, the impact resistance of the rear cover is significantly improved. At the same time, the design of the air duct and air guide plate ensures good heat dissipation performance inside the cabinet and extends the service life of the equipment.

[0016] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.
[0017] like Figure 1 to Figure 4 As shown, a high-strength rear cover plate of a switch cabinet comprises a rear cover plate body 1, a reinforcing plate 2 is arranged on the rear cover plate body 1, the reinforcing plate 2 is welded to the rear cover plate body 1, a plurality of vertical corrugated protrusions 3 are bent on the reinforcing plate 2, the corrugated protrusions 3 face the inner side of the switch cabinet, and the overall strength and impact resistance of the rear cover plate body 1 are improved by arranging the corrugated protrusions 3, and the upper and lower ends of the reinforcing plate 2 maintain a gap with the upper and lower edges of the rear cover plate body 1, so that on the reinforcing plate 2 An air duct 4 is formed between the bent corrugated protrusion 3 and the rear cover plate body 1. A heat dissipation hole 5 is opened at the upper end of the rear cover plate body 1. The heat dissipation hole 5 is located in the area covered by the corrugated protrusion 3. An air guide plate 6 is connected to the corrugated protrusion 3. A welding hole is processed below the air guide plate 6, and the welding hole is welded to the corrugated protrusion 3. The air guide plate 6 is in the air duct 4. The air guide plate 6 is obliquely arranged to guide air toward the heat dissipation hole 5. When the heat in the air duct 4 is conducted upward, the air guide plate 6 guides the heat to the heat dissipation hole.
[0018] The rear cover plate body 1 has connecting edges 7 bent on both sides. In this embodiment, the reinforcing plate 2 has supporting edges 8 bent on both sides. Plug welding holes 9 are evenly distributed between the supporting edges 8 and the corrugated protrusions 3. The plug welding holes 8 are connected to the rear cover plate body 1 by welding.
