Description

Technical Field

[0001] This utility model belongs to the field of power switchgear technology, specifically relating to a main frame structure of a power switchgear. Background Technology

[0002] In power systems, power switchgear is a key device for controlling and protecting power equipment, and the stability of its main frame structure directly affects the operational safety and service life of the equipment. Existing power switchgear main frame structures mostly adopt a linear frame design, assembling components through simple bolt connections or welding. However, this structure has significant drawbacks: firstly, when subjected to vertical loads or horizontal impacts, the linear frame is prone to deformation due to stress concentration, especially in high-vibration operating environments, where loosening of connections is a prominent issue; secondly, traditional structures lack effective three-dimensional reinforcement designs, making it difficult to guarantee overall stability when the cabinet is subjected to lateral forces or eccentric loads generated during equipment installation.

[0003] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

[0004] The main purpose of this utility model is to provide a main frame structure for a power switchgear. Through innovative bending section design, multi-dimensional reinforcement rod layout, and three-dimensional reinforcement frame connection, a high-strength spatial support system is constructed, which effectively improves the deformation resistance and impact resistance of the main frame structure. At the same time, the connection method with the top and bottom plates of the cabinet is optimized to ensure the stability of the overall structure under complex load conditions and meet the requirements for safe and reliable operation of power equipment.

Several third reinforcing rods are provided between the fifth and sixth bends, and several fourth reinforcing rods are provided between the seventh and eighth bends (the overall structural stability is improved through the bends and reinforcing rods).
