[0002] With the development of power systems and the growing demand for electricity, the safety and reliability of distribution cabinets, as key equipment for power distribution and control, have become crucial considerations. The internal structure of the distribution cabinet is complex, containing a variety of switchgear, conductive components and supporting structures. The reasonable design and layout of these components directly affect the overall performance and operational safety of the distribution cabinet. Especially under the trend of high-density wiring and compact design, how to ensure the stable installation and electrical isolation of various components in the distribution cabinet to avoid short-circuit accidents caused by vibration, external force or component aging has become one of the urgent problems to be solved in the field of power distribution technology.

[0003] In the traditional design of distribution cabinets, the horizontal bar is a key component connecting the upper and lower conductive plates. Its fixing method mostly relies on simple upper and lower conductive plate supports. This design is prone to the horizontal bar loosening or even contact with other conductive components during long-term operation or when subjected to external impact, thereby causing short circuit risks and posing a threat to the stable operation of the power system.

[0004] In view of the above technical background, the present application proposes a new type of distribution cabinet structure, which aims to fundamentally improve the fixing stability and electrical safety of the horizontal row through an innovative horizontal bracket design.
