The monitoring cabinet is used to combine the installation panel, plug-ins, plug-in boxes, electronic components, equipment and mechanical parts into a whole installation box.
The monitoring cabinet consists of a frame and a cover plate (door), which is generally rectangular and placed on the ground. Provide appropriate environmental and safety protection for the normal work of electronic equipment. This is the first level assembly next to the system level. A cabinet without a closed structure is called a rack.
The monitoring cabinet has good technical performance. The structure of the cabinet should be designed physically and chemically according to the electrical and mechanical properties of the equipment and the requirements of the use environment, so as to ensure that the structure of the cabinet has good rigidity and strength, as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation. In addition, the monitoring cabinet should have the performance of vibration resistance, impact resistance, corrosion resistance, dust prevention, waterproof and radiation protection, so as to ensure the stable and reliable operation of the equipment. The monitoring cabinet should have good availability and safety protection facilities, which are convenient for operation, installation and maintenance, and can ensure the safety of operators. Network cabinets should be convenient for production, assembly, debugging, packaging and transportation. The monitoring cabinet shall meet the requirements of standardization, standardization and serialization. The cabinets are beautiful in appearance, applicable and harmonious in color.
In the early days, most of the monitoring cabinets were made of castings or angle steel connected or welded into a cabinet frame by screws and rivets, plus a cover plate (door) made of thin steel plate. This kind of cabinet has been eliminated because of its large size and simple appearance. With the use of transistors and integrated circuits and the miniaturization of various components, the structure of the cabinet is also developing towards miniaturization and modularization. /The monitoring cabinet has developed from the integral panel structure in the past to the box and plug-in structure of a certain size series. The assembly arrangement of boxes and plug-ins can be divided into horizontal arrangement and vertical arrangement. The materials of monitoring cabinets are generally thin steel plates, steel profiles with various cross-sectional shapes, aluminum profiles and various engineering plastics. The frame of the monitoring cabinet is not only connected by welding and screws, but also by bonding process.
