Technical Field

[0001] This invention relates to the field of switchgear frame technology, and in particular to a switchgear frame that can be disassembled and assembled. Background Technology

[0002] A switchgear is an electrical device assembled from primary and secondary equipment according to a specific scheme. It is used to control and protect lines and equipment. Based on the incoming and outgoing line voltage levels, switchgear can be divided into high-voltage switchgear and low-voltage switchgear. As the main structure of the switchgear, the frame provides stable support and fixation for the internal components, ensuring stable operation of the equipment. The frame effectively isolates the inside of the switchgear from the external environment, preventing external factors from interfering with the internal equipment, while also protecting the safety of operators. The assembly of the switchgear frame usually involves steps such as the installation of the foundation steel and the positioning and fixing of the cabinet. Since different electronic components are mounted on the mounting beams, the foundation steel is prone to deformation, resulting in a large deviation in the verticality of the overall cabinet. Moreover, the current frame installation and maintenance are cumbersome, affecting the overall safety and stability. Therefore, we propose a switchgear frame that can be disassembled and assembled to solve the problems mentioned above. Summary of the Invention

[0003] To overcome the problems that the mounting of different electronic components on the installation beams can easily cause deformation of the foundation steel, resulting in a large deviation in the verticality of the overall cabinet, and that the current frame installation and maintenance are cumbersome, affecting the overall safety and stability.
