Description

Technical Field

[0001] This utility model belongs to the field of low-voltage switchgear frames and relates to a low-voltage switchgear frame structure. Background Technology

[0002] In power systems, low-voltage switchgear is a critical power distribution device, and its performance and reliability are essential for the stable operation of the entire power system. However, the traditional low-voltage switchgear frame structure has certain limitations in design, especially in terms of protection level and structural strength, making it difficult to meet the growing application requirements.

[0003] Firstly, from the perspective of protection level, the frame structure of traditional low-voltage switchgear is often designed relatively simply, lacking sufficient protective measures. In harsh environmental conditions, such as high humidity, dusty environments, or locations containing corrosive gases, these low-voltage switchgear are easily affected by external factors, leading to damage to internal electrical components and consequently affecting the normal operation of the entire power system. Furthermore, with the continuous development of industrial automation, higher requirements are being placed on the protection level of low-voltage switchgear to adapt to more complex and demanding working environments.

[0004] Secondly, from a structural strength perspective, the design and manufacturing process of traditional low-voltage switchgear frames often neglects material selection and structural optimization. This makes the switchgear prone to deformation or damage when subjected to external loads or stresses generated by internal electrical components. Especially in applications requiring high-strength support, such as large industrial equipment or data centers, the frame structure of traditional low-voltage switchgear often fails to meet the requirements.

[0005] Furthermore, the traditional low-voltage switchgear frame structure also presents certain inconveniences in terms of assembly and maintenance. Due to its complex structure or unreasonable connection methods, the assembly process is cumbersome and time-consuming. Simultaneously, during maintenance, the limitations of the frame structure often make it difficult to quickly and accurately inspect and replace internal electrical components. This not only increases maintenance costs but also affects the overall operating efficiency of the power system.

[0006] To address the above issues, it is necessary to innovate the design of the low-voltage switchgear frame structure. By adopting new materials, optimizing structural design, and improving connection methods, the protection level and structural strength of the low-voltage switchgear can be improved, while simplifying the assembly and maintenance process.

[0007] In summary, traditional low-voltage switchgear frame structures have significant shortcomings in terms of protection level, structural strength, and assembly and maintenance. To meet the growing application demands and improve the overall operating efficiency of power systems, it is necessary to innovate the design of low-voltage switchgear frame structures to provide a more reliable, efficient, and easy-to-maintain low-voltage switchgear solution. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a low-voltage switchgear frame structure that, based on the conventional low-voltage switchgear structure, reduces the cost of the device and improves work efficiency while meeting the requirements of frame structure and strength performance.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage cabinet frame structure, comprising four vertically arranged columns, multiple horizontally arranged crossbeams, multiple longitudinally arranged longitudinal beams, and tee fittings for connecting nodes; the columns are respectively arranged at the four corners of the frame, and the top and bottom are connected by two crossbeams to form a rectangular frame, and the longitudinal beams connect the front and rear frames along the depth direction of the cabinet, wherein the ends of the columns, crossbeams, and longitudinal beams that are close to each other are connected by tee fittings, ultimately forming an overall frame structure.

[0010] Optionally, the columns, beams and longitudinal beams are all closed profile structures with a hollow rectangular cross-section and a profile wall thickness of 2.0 mm.

[0011] Optionally, the column is provided with a ruffled structure extending outward from the frame along its height edge.

[0012] Optionally, the crossbeam has a pleated structure extending outward from the frame along its length.

[0013] Optionally, the pleated structures of the crossbeam and the column have equal extension lengths, and the projections of the two pleated structures within the frame are continuous and connected.

[0014] Optionally, the hem extension length is 23mm.

[0015] Optionally, the tee component includes three orthogonal connection interfaces, wherein the axes of the two horizontal interfaces are perpendicular to each other, the axis of the vertical interface forms a 90-degree angle with the horizontal plane, and each interface is provided with a snap-fit ​​structure that matches the end structure of the column, crossbeam, and longitudinal beam.

[0016] Optionally, the tee component is provided with at least one lifting hole.

[0017] Optionally, two side longitudinal beams are also provided on the upper part between the front and rear frames.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1) Enhanced Protection Level: The low-voltage switchgear frame structure adopts a closed profile design, with pleated edges extending outwards from the columns and beams. This design significantly enhances the protection level of the switchgear. The pleated edges effectively prevent dust, moisture, and other harmful substances from entering the switchgear, protecting the internal electrical components from external environmental damage, thereby extending the service life of the low-voltage switchgear and improving its operational reliability.

[0020] 2) Enhanced structural strength: The use of enclosed profiles and the design of the pleated structure not only improves the protection level but also significantly enhances the overall strength of the low-voltage switchgear frame. This structure can effectively resist external loads and stresses generated by internal electrical components, reducing the risk of deformation and damage, and ensuring stable operation of the low-voltage switchgear under various working conditions.

[0021] 3) Easy Assembly and Disassembly: The frame structure of this low-voltage switchgear uses a T-joint to connect the uprights, crossbeams, and longitudinal beams. This connection method is simple and quick, facilitating on-site assembly and disassembly. The T-joint contains three orthogonal connection interfaces, each with a snap-fit ​​structure that matches the end structure of the uprights, crossbeams, and longitudinal beams, making the assembly process more efficient and accurate. At the same time, this connection method also facilitates subsequent maintenance and repair work, reducing maintenance costs and time.

[0022] 4) Modular Production and Transportation: The frame structure of this low-voltage switchgear supports modular production. Each component, such as uprights, crossbeams, longitudinal beams, and tee fittings, can be manufactured independently and then assembled using standardized interfaces. This production method improves production efficiency and reduces manufacturing costs. Simultaneously, the modular design facilitates transportation and storage, reducing the risk of damage during transport and lowering logistics costs.

[0023] In summary, the low-voltage switchgear frame structure, through innovative designs such as enclosed profiles, pleated structures, and tee connectors, significantly improves the protection level, structural strength, and working efficiency of the low-voltage switchgear. At the same time, it is easy to assemble, disassemble, transport, and maintain, resulting in significant economic and social benefits.
