Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and more specifically, to an electrical control cabinet. Background Art

[0002] In the field of industrial automation and electrical control, electrical control cabinets are important devices for centralized control and protection of electrical equipment. Their performance and reliability directly affect the stable operation of the entire control system. First of all, the existing electrical control cabinets have a relatively simple structure and have certain design defects. In actual use, when the operator opens the cabinet door for operation or maintenance, the cabinet door is easily blown by the wind and automatically closed. This unexpected situation not only brings inconvenience to the operator, but may also interfere with the ongoing operation or maintenance work, and even cause safety hazards. In addition, when installing the control cabinet, it is usually necessary to open a cable outlet at the bottom of the control cabinet according to the on-site wiring situation for the introduction and extraction of cables. This requires the installer to temporarily open a cable outlet on site, increasing the installation workload.

[0003] Secondly, various circuit components and equipment, such as circuit breakers, contactors, relays, etc., usually need to be installed inside the electrical control cabinet. In order to facilitate the installation and layout of these components, the prior art usually uses a mounting frame to fix them. However, when the mounting frame is installed inside the control cabinet, the operation process is relatively cumbersome and inconvenient. The existing mounting frame is usually connected to the inner wall of the control cabinet with fasteners such as bolts and nuts. The installation and disassembly process requires the use of tools, which is time-consuming and labor-intensive. This installation method not only affects the installation efficiency, but also brings inconvenience to subsequent maintenance and replacement work.

[0004] In addition, in the wiring design of the electrical control cabinet, multiple cables and lines are usually required to be laid in the electrical control cabinet to connect various electrical components and equipment. However, the existing control cabinet wiring method usually lacks reasonable planning and management, resulting in the lines inside the control cabinet being messy and lacking in organization. This wiring chaos not only affects the aesthetics of the interior of the control cabinet, but also brings great inconvenience to subsequent maintenance and troubleshooting. At the same time, the messy lines also increase the risk of cable damage and short circuit, affecting the reliability and safety of the control system. Utility Model Content
