Storage screen / distribution screen / DC panel cabinet

High voltage DC power distribution room cabinet, used for control, protection, monitoring and operation of circuit breakers and other electrical power supply; AC too; the main breaker control operations in accordance with the type of power to decide; DC power supply cabinet has the following ratio of the power cabinet Benefits: 1. DC power supply cabinet without considering the three phase problem; 2. DC power supply cabinet to the battery pack can be fully charged in advance in case of AC power supply is normal, when the AC power failure, the battery-fed, able to ensure circuit breaker operation, control, protection and monitoring of electricity. In short, more secure and reliable. GZDW series DC screen is Epps WebEx The power requirements, high reliability product line consistent with the operating conditions and design. Standard one cabinet is charging, the power supply combined in a cabinet, and can be equipped with three charging module. Mainly for 110KV and below substation, opening and closing, and change the user. Our company is strong in technology, product performance and stability, timely service in place, won the trust of customers. Products used in many major domestic and international power projects. Products in strict accordance with international and national quality assurance system of production, in line with JB / T5777.4-200 "power system DC power supply General technical and safety requirements" and DL / T459-2000 "system DC power supply cabinet ordering technology" requirement. System Features: The unique modular design of switching power supply, N + 1 hot backup. ? Wide input voltage range, power grids applicability and can be used relatively harsh environment of the place. ? Charging module can be hot plug, line maintenance, and convenient. ? Hardware low difference between automatic current technology, the module maximum output current unbalance is less than ± 3%. ? System design using IEC (International Electrotechnical Commission), UL and other international standards, reliability and security fully guaranteed. ? Monitoring Module using a large-screen LCD display or touch screen, sound and light alarms. ? Monitoring module can be parameterized by the various parts of the system, user-friendly, easy to operate. ? With smooth adjustment of output voltage and current, battery automatic temperature compensation, and other advanced features. ? Open interface design, with powerful communications features, it is easy to realize the substation RTU devices connected to the computer monitoring system or power plant DCS. ? Three of distributed control monitoring system, power supply system, "telemetry, remote, remote, remote tune" and unattended. ? Automatic battery management and protection, real-time automatic monitoring battery terminal voltage, charge and discharge current, and control of both charge the battery and float with battery over / under voltage and charge overcurrent audible alarm.
