The outdoor communication cabinet is a solution that can be installed outdoors, that is to say, the main equipment, battery, power system, and transmission system are all stuffed into the cabinet, and a station is built on the side of the road, and a communication pole is built. Then I will take you through this article. Get up and take a look at the manufacturing process of outdoor communication cabinets and what to pay attention to in cabinet design. I hope it can be helpful to friends in need.
Manufacturing process of outdoor communication cabinet
Appearance of coating
The surface of the coating should be continuous and uniform, and the texture should be consistent with the corresponding standard sample, and there should be no defects such as nodules, shrinkage cavities, blisters, pinholes, cracks, peeling, pulverization, particles, sags, exposed bottoms, and inclusions of dirt .
For cabinets without spraying treatment, the gloss and texture of the outer surface should be uniform and beautiful.
Coating adhesion
The coating on the surface of the cabinet meets the requirements of level 1 in Table 1 of GB/T 9286-1998 after the adhesion test.
Coating impact resistance
The coating on the surface of the cabinet has no defects such as radial cracks and gaps after the impact test.
Coating anti-aging
The coating on the cabinet surface is anti-aging.
The coating is resistant to solvents
After the coating on the surface of the cabinet has passed the solvent resistance test, there should be no loss of gloss, obvious color loss or signs of being wiped on the surface by visual inspection.
Points for attention in cabinet structure design
The main frame of the cabinet
The main frame of the cabinet should be standardized to facilitate the combination of cabinets with different functions. The welding structure is adopted, and the outdoor electrostatic spraying powder process ensures the mechanical strength, rigidity and reliable performance of corrosion resistance of the cabinet. The lifting device should be installed on the main frame so as to bear the weight of the cabinet itself when lifting.
Inside the cabinet
The internal structure of the cabinet can be based on 19in, 21in,. 23in or 24in standard serialization; the rack height dimension should be standardized according to 25mm or 44.45 (U) standard and the design has strong versatility. In specific use, it can be expanded and combined according to actual needs to meet the installation of communication equipment. The communication and power lines inside the cabinet can be fixed by laying or binding. The layout position is in the wiring trough or tie plate on the left and right sides of the cabinet; the bottom of the cabinet should be opened through the wire hole. All the cables located outside the cabinet pass through this hole; multiple cabinets are routed on the base outside the cabinet, and the bottom of the cabinet should be equipped with wire holes and coils. The wire holes and openings should be polished without any Acute burrs and other injuries.
Cabinet base
The base of the cabinet should be designed in a standardized manner to facilitate the combination of cabinets with different functions. Hot-dip galvanized steel sheets with a thickness of not less than 2.0mm are used, and the height of the base is not less than 200mm.
The structural part of the cabinet door panel
The battery cabinet should have a hydrogen discharge device. The area of the hydrogen discharge hole should meet the requirements of the national standard GB7260.1; it supports flexible replacement of the cabinet door; the door opening angle is greater than 120°, and the cabinet door has a limit device; the limit device should be on the cabinet door When it is opened, it will automatically play and start, and when the limit needs to be canceled, it will be closed manually; the cabinet door must be equipped with a lock. The locking device of the lock should be greater than or equal to three points. At the same time, it supports the padlock method; the cabinet door hinges use inner dumpling chains, and the number of configurations should not be less than 3, and the number of hinges for cabinets with a height of 1800mm should be 5.
The setting of the vent should be inclined downward to prevent rainwater from entering the interior of the cabinet. At the same time, in order to prevent rodents or insects from entering the interior of the cabinet, dust-proof nets should be arranged at the vents, and the dust-proof nets should also be dust-proof. Easy to clean and maintain, corrosion resistance and so on. The structure of the cabinet door panel should meet the reasonable design of the air duct when using industrial-grade ventilation equipment. The heat dissipation performance is stable and reliable, and the service life is long. The good ventilation and heat dissipation effect can not only effectively reduce the temperature emitted by the main equipment, but also improve the safety of equipment use.
Cabinet grounding protection
The cabinet should be equipped with a grounding bar. In order to ensure the reliable grounding of the grounding bar, its cross-sectional area is required to be greater than or equal to 50 square millimeters. The metal copper with anti-corrosion treatment is used on the material and connected to the metal parts of the grounding bar. The detection resistance between the grounding bar and the grounding bar should be less than 0.1 Q. The cross-sectional area of the copper core in the grounding wire connected to the ground bar should be greater than 16 square millimeters and the grounding point must be clearly marked.
Anti-theft protection
The cabinet body cannot have a structure that can be directly disassembled from the outside and affects its own use and safety; the cabinet door must be equipped with reliable locks, and cannot be operated if it is closed with damage performance; the anti-destructive performance of the locks used in the cabinet should meet the requirements of Class B requirements in GA/T 73-1994.
Protection level
The protection level of the power supply equipment cabinet and equipment cabinet must meet the requirements of IP55 in GB 4208-2008 The protection level of the equipment compartment of the integrated cabinet must meet the requirements of IP55 in GB 4208_2008 The protection level of the battery compartment and battery cabinet of the integrated cabinet must meet the requirements of GB 4208-2008 The requirements of IP45.
The above is what I have shared with you about the manufacturing process of outdoor communication cabinets and what to pay attention to in cabinet design. For more questions, please pay attention to us.
