GZDW DC screen

GZDW直流屏

GZDW直流屏

  • 详细描述
  • 原理及特性
  • 技术参数
  •   DC screen is the abbreviation of GZDW intelligent electric power operation power system, which is composed of charging screen and battery screen. After the main and standby two AC power sources are input through the dual AC switching device, the high-frequency switch charging module converts the three-phase AC power into DC power, powers the closing load and the control bus, and charges the maintenance-free battery. When the mains power is cut off or abnormal, the battery discharges emergency power supply. Reliably meet the power supply requirements of the DC control power supply and the opening and closing of the high and low voltage switches in the normal or abnormal state of the power transmission and distribution system.

      This device adopts modular design and redundant configuration, and combines the advanced high-frequency switching power supply in the DC field with PLC and touch screen control to realize a new generation of unattended DC power supply products. Reliable operation, high degree of automation and convenient operation.

      is widely used in electric power, petrochemical, metallurgy, textile, mining, railway and other fields to provide stable and reliable DC power supply for high and low voltage and secondary equipment in substations and distribution rooms of industrial and mining enterprises.
