In short, the working principle of the DC screen is to convert AC power into DC power to provide power for the protection of electrical secondary equipment, operating mechanism and indicator light. Under normal circumstances, the charging unit will charge the battery and provide DC power to the regular load. 1.
We also call the DC screen the DC power supply operating system. It is a new digital control, protection and management equipment, which is composed of AC power distribution unit, charging module unit, step-down silicon chain unit, DC feed unit, power distribution monitoring unit, monitoring module unit and insulation monitoring unit.
The GZDW series of microcomputer-controlled DC screens are suitable for substations, power plants, industrial and mining enterprises, electrified railways and high-rise buildings of different voltage levels, and can be used as operating power and control power for high-voltage switches, relay protection and automatic devices.
The DC screen with microcomputer control adds a central monitoring unit, making the interface of the DC screen more friendly, and the operation and control simpler. 5、 What is the working principle of DC screen?
The DC panel is mainly composed of AC power input unit, rectifier unit, battery charge and discharge control unit, battery pack, DC feed out, bus monitoring (voltage measurement, insulation, flash), etc.
DC panel is generally used in high-voltage distribution room, hydraulic power plant, thermal power plant, various substations and other users who use DC equipment
