Description

Technical Field

[0001] The utility model relates to the field of electric control cabinets, in particular to an electric control cabinet. Background Art

[0002] A control cabinet is a device that is arranged to meet the requirements of normal operation of the power system, is easy to repair, and does not endanger the safety of people and surrounding equipment. The switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. The electrical equipment in the cabinet will generate heat during operation, and the heat will accumulate in the cabinet, causing the temperature to rise, which may cause equipment failure or even fire and other safety hazards. When the electrical cabinet is used, a cooling fan needs to be installed to provide air circulation and heat dissipation to effectively reduce the temperature in the distribution cabinet;

[0003] For example, an electrical control cabinet disclosed in the utility model with authorization announcement number CN220421187U includes a cabinet body, a fixed shell is fixedly installed inside the cabinet body, a plurality of mounting holes are opened on the surface of the fixed shell, and adjustment plates are rotatably connected to the inner sides of the mounting holes through rotating columns, and a mounting plate is fixedly installed on the surface of the adjusting plate, and a cabinet door connected to the inner part of the cabinet body is rotatably connected to one side of the cabinet body, a fixed frame is fixedly installed on the bottom of the cabinet body, a bracket is arranged inside the fixed frame, and casters are respectively arranged at the four corners of the bottom of the bracket. The holes and adjustment plates are conducive to allowing the operator to complete the maintenance and installation of electrical components more conveniently.
