At present, domestic operators have covered most areas with communication base stations, and many communication facilities are directly placed outdoors, so they will choose special outdoor communication cabinets for equipment protection. So what are the design points of the outdoor communication cabinet? What are the technical parameters? Today, the editor will introduce in detail “the key points of outdoor communication cabinet design, what are the technical parameters?”
Design points of outdoor communication cabinet
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 serialized according to the standard of 19in, 21in, 23in or 24in; the height of the rack should be standardized according to the standard of 25mm or 44, 45 (U), and the design is highly versatile. 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. All other cables pass through this hole; multiple cabinets are routed on the base outside the cabinet, and the bottom of the cabinet should be equipped with a wire hole and a coil. people.
Cabinet base
The base of the cabinet should be designed in a standardized way to facilitate the combination of different functional cabinets. Use hot-dip galvanized steel sheets with a thickness of not less than 2.0mm, and the height of the base should not be 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 the flexible replacement of 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, and support padlocks at the same time; The number should be no less than 3, and the number of hinges for a cabinet 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 cabinet, dust-proof nets should be arranged at the vents. The dust-proof nets should also have the characteristics of dust resistance, easy cleaning and maintenance, and corrosion resistance. 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 to ensure reliable grounding of the grounding bar. , 1Q. The cross-sectional area of the copper core in the ground wire connected to the ground bar should be greater than 16 mm2 and the ground 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.
Technical parameters of outdoor communication cabinet
The cabinet has the characteristics of dustproof, sunscreen and rainproof, and is suitable for the outdoor environment in most areas;
The cabinet body adopts ventilation and heat dissipation, and a heat exchanger can also be used as a heat dissipation device, MTBF≥50000h;
The cabinet adopts semiconductor cooling method and is equipped with lighting fixtures;
The cabinet has power and environment monitoring functions, which can realize alarms such as power failure, power failure, and battery voltage and upload them;
The layout of the cabinet is reasonable, the operation of cable introduction, fixing and grounding is convenient, and the maintenance is convenient; the cables have independent cable entry holes and will not interfere with each other.
The cables used in the cabinet are made of flame retardant materials.
The cabinet adopts on-site assembly method;
