A DC screen is an independent power system that is unaffected by the operation modes of systems like generator plants. When external AC power is cut off, the DC screen's battery continues to supply DC power, making it highly reliable and safe. The DC screen is composed of units such as the AC-DC distribution unit, charging module unit, step-down silicon chain unit, DC power distribution unit, distribution monitoring unit, monitoring module unit, and insulation monitoring unit. It represents a new type of DC system with digital control, protection, management, and measurement capabilities. Primarily used in small and medium-sized power plants, hydropower plants, various transformer stations, and other users of DC equipment (such as petrochemical, mining, and railway industries), the DC screen is suitable for applications like switchgear operations, instruments, meters, relay protection, and emergency lighting in secondary circuits.
