    General info

    Electric control panel and substations to function as power supply needed for opening & closing of high-voltage switch in case of normal operation or emergency state relaying protection automatic protection emergency lighting and sound project. It also serves as power supply in such occasions as metallurgical industry railway mine petrochemical industry post telecom hospital bank hotel tall building and computer network etc. The microcomputer-controlled DC power supply cubicle can function as a DC power supply for the power generation plant substation and for unattended and remote monitoring and controlling.


    Ambient temperature:

    Maximum +40°C
    Maximum 24 hour average +35°C
    Minimum (according to minus 15 indoor classes) -10°C

    Ambient humidity:
    Daily average relative humidity less than 95%
    Monthly average relative humidity less than 90%
    Height above sea level at site less than 2000m
    Earthquake intensity less than 8 degree


    Feature

    Intelligent dual-power switching: There is double AC power input way for the panel. One is the way for working power; another is the way for standby power. When the power fails, the system automatically switches to standby power.


    Automatic voltage converter: The panel automatically converts voltage value according to voltage of closing bus-bar. The panel uses a pressure relief device-level or pressure relief device. This work is stable and reliable.


    Multi-protection design: The panel has surge protectors which prevent over-voltage of the power supply. There are overvoltage protection, current limiting protection, short- circuit protection, module parallel protection, over-temperature protection and over-current protection system as a whole can improve the safe and reliable operation.


    N +1 redundancy design: The charging module has N + 1 to improve reliability, the charging module has self cooling, supports live hot plugging-in and pulling, is easy to maintain.


    Centralized Monitoring Function: Coordinate with the central monitoring or control of the DC power supply components and operating parameters of the role of the state, at the same time concentrate on each module Parameters upward crew transmission, PC and transmitted under the order. Use of the structural design of building blocks, can lose control Level. All AC voltage, current, spare each other automatically switching; coordination or control supply bus-bar of current, voltage parameters. Battery voltage parameters, battery charge and discharge current parameters; system insulation parameters; reclosing switch monitoring, control switches, batteries Melting Off work for the state of insulation fed a control loop (optional); Patrol battery (optional), monitor the environment temperature.
