    LED control electric box / cabinet ■ Overview LED control

    electrical cabinet applies to the information screen, traffic guidance

    screen, advertising screen, car screen, stadium screen, stage rental,

    screen and staircase screen display control system, which serve to

    control the LED display, executive function, through power, protection,

    monitoring and distribution of electric energy role. ■ Usage and

    Functionality: The power monitor: screen step-by-step delay power

    through the control box / cabinet pre-installed programs, in order to

    avoid the catchy switch tripping fault, but also reduce the impact on

    power in the power-on screen body. The fault alarm status box on the

    control interface of each power supply power-on state of alarm

    indicator. And through the communication module of the switch to remote

    monitoring and operation. Fire Monitoring: install smoke detectors in

    the top of the screen within the screen if the fire occurred, the smoke

    detector probe signal to the control box, control box to start alarm

    message, the control box / cabinet received signal switch automatically

    shut power, so as to protect the screen. Temperature monitoring: the

    upper part of the on-screen to install the temperature sensor, computer

    control interface can be as real-time temperature monitor on the

    display. Automatic mode, the screen body temperature exceeds 54 ℃,

    the control interface on the current temperature value will be flashing

    prompts; when the screen body temperature exceeds 60 ℃, the

    temperature sensor will send the signal to the control box / cabinet,

    then the control box / cabinet received signal is in charge of auxiliary

    contacts of the switch action, switch power failure display will

    automatically shut power in order to prevent equipment failure and

    causing a fire. Users can accord to their usage, set alarm temperature

    and off-screen temperature on monitoring interface. Door alarm

    monitoring: the inside of the installation of the threshold switch in

    the power distribution cabinet door, door alarm monitoring interface

    monitoring to prevent someone opened the door to destruct the

    distribution cabinet which installed in the outdoors, Display automatic

    control: when groups display and perform in different functions, when

    you need a control system to control their respectively tasks in the

    control box to the implementation of state corresponding function can be

    done through the PLC, you can also choose the time control switch, time

    relay, communications switches and other electrical components to

    achieve the user's orders of the operating instructions. ■

    Implementation of standards LED control box / cabinet is assembled by

    the manufacturer are fully type test, advanced low-voltage switch box /

    cabinet, it is consistent: The national standard GB7251 - 87 low voltage

    switchgear; Professional standards ZBK36001 - 89LED voltage switchgear;

    International standard IEC439. ■ Use of the environment Ambient

    air temperature is not higher than +40 ℃, and less than a 5

    ℃, average temperature is not higher than +35 ℃ within 24

    hours; Relative temperature of +40 ° C maximum temperature does not

    exceed 50%, at lower temperatures allows relatively high temperature,

    such as +20℃ 90%; The air is clean, non-corrosive and explosive

    gases, non-conductive and without dust can damage the insulation; No

    significant shake , shock and vibration occasions, if mounted vertically

    the tilt should not exceed 5 degrees; Altitude is not over 2000 meters;

    Switchgear for the following temperature transportation and storage: 25

    ℃ to +55 ℃, in a short period of time (not more than 24

    hours) does not exceed +70 ℃; If users can not meet the above

    conditions should consult with the manufacturer. ■ The main

    technical parameters Rated insulation voltage 660V; Rated working

    voltage 380V; Auxiliary circuit rated operating voltage AC 380V, 220V;

    Busbar rated current: 10A ~ 1600A; Busbar rated short time withstand

    current: 50KA (rms) 1 seconds; Busbar rated peak withstand current:

    105KA; Branch busbar rated current: 630A, 800A; Branch bus bar rated

    short time withstand current: 30KA, 50KA (rms) of 1 second; Branch

    busbar rated fixed peak withstand current: 63KA, 105KA; Housing

    protection grade IP40. ■ Selection and Configuration In general,

    unit selection and configuration of an electric switching equipment will

    be begin from the following aspects: - Cabinet choices: The

    materials have cold rolled steel or angle iron (for welding cabinet, low

    cost, high strength general-purpose type); deposited aluminum zinc steel

    or galvanized steel (used to assemble the cabinet); stainless steel

    plate (not permeability) ; aluminum ((permeability); the SMC composite

    unsaturated materials. Installation types: indoor and outdoor. -

    The cabinet's main electrical components brand choice: High price: ABB,

    Schneider, United States AB, Mitsubishi, Siemens, Omron, Muller,

    Weidmuller, Phoenix, Hager, Legrand, etc.. Moderate price: Changshu, the

    Long March, China through Shanghai Wuchang, Shihlin, refinement, and so

    on. Low price: Tengen, Chint, West Germany, the people of appliances,

    Watertown, Taian, river, etc.. - Cabinet auxiliary components

    Copper busbar connections, aluminum row connection and wires connected.

    ■ Control box / cabinet classification A single control box /

    cabinet Control box / cabinet Simple control box / cabinet Intelligent

    control box / cabinet Built-in control box Independent control box /

    cabinet ■ Structure Cabinet by steel sheet metal forming, take the

    20mm modulus for the standardized design, with versatility of structural

    components and high mechanical strength; upper cabinets body is main

    busbar room, the front is the electrical room, the rear is the cable

    in/out chamber, each room have steel or insulation board for isolation

    in order to ensure safe usage; There have galvanized or two kinds of

    electrostatic powder coating on the surface protective layer of the

    cabinet structure parts, so it with reliable quality and beautiful

    color; ■ Dimensions Number of electrical components according to

    user needs and the control box / cabinet is belongs to a custom product.

    ■ Installation: Household type, outdoor type and semi-outdoor type

    ■ Order Attention The user should be provided (the user can also

    provide specific requirements, all of the following are required to

    provide information for the user by the Company engineers designed and

    then handed over to the production after the final validation of the

    user): Primary circuit of the program and in-line system diagram;

    Secondary circuit diagram, if the user does not make demands, will take

    the factory standard wiring; Switchgear the Pareto substation plan;

    Detailed specifications for each loop circuit elements; The control box

    / cabinet surface color; Other special requirements.
