Intelligent DC Power Supply System with Busbar Voltage Loss Compensation, Battery Health Monitoring, and Modularized Power Supply Unit
The intelligent DC power supply system integrates an AC distribution unit, charging module, feeder unit, battery bank, monitoring unit, voltage and current monitoring instruments, insulation monitoring device, silicon-based voltage reduction circuit, and battery management unit. It serves as a critical component of substation power systems and power plants, providing power for automatic control, power equipment, relay protection, instrumentation, signaling, communication, and emergency lighting systems.
The DC power supply system is applied in large, medium, and small power plants as well as substations, providing the necessary DC power for high-voltage switch operations (opening/closing), relay protection, automatic control, emergency lighting, illumination, and signaling during both normal operation and fault conditions.
It also serves industries such as metallurgy, railways, mining, petrochemicals, postal services, telecommunications, healthcare, banking, hotels, high-rise buildings, and computer networks. This product complies with the JB/T 57774-2000 standard "General Technical Requirements and Safety Requirements for DC Power Equipment in Power Systems".
