Tianjin Direct Current Screen Power Factory, Tianjin Direct Current Screen Power Price, Tianjin Direct Current Screen Power Suppliers - Direct current switchgear assembly (Direct-current switchgear assembly) consists of one or more low-voltage switchgear, converter units, floating charge devices, and related control, measurement, signaling, protection, and regulation units. The manufacturer is responsible for all internal electrical and mechanical connections, and the components are assembled together using structural parts. It is mainly composed of several major parts: power input system (AC input), dual-power mutual transfer system, charger control system, charger, DC distribution system, insulation monitoring system, integrated controller (system monitoring and control system, the brain of the DC screen), flash system, communication system, and battery. The key components ensuring the reliability of the DC screen include the integrated controller, dual-power mutual transfer, charger control, and charger selection. The integrated controller is responsible for monitoring the operation of the DC screen, knowing every aspect of its operation, and keeping the system running optimally. It controls the battery inspection unit, which provides voltage monitoring for each battery section to detect battery deterioration early and replace them promptly, preventing catastrophic consequences such as the inability to provide DC power to the system during power outages. The insulation monitoring system protects the DC screen from damage to its own or external equipment due to external devices or system grounding. The configuration and rational selection of batteries ensure the normal operation of the system during power outages and can prevent the DC screen from being damaged, which could lead to interruptions in system power supply.
