Zhaopin Shengda supply DC panel GZDW7AH ~ 1000AH

A: GZDW About DC screen DC screen DC power supply operating system for short. GM called intelligent maintenance-free DC power screen, referred to as DC-screen, universal model GZDW. DC panel suitable for 10 ~ 500kV substations, power plants and high-rise buildings, residential quarters and other power distribution room, and a small captive power plant, as a high-voltage switch, relay protection, automatic devices, control operating systems, the control power supply and emergency lighting power supply. But also it can be applied to other places requiring DC power supply (such as petrochemical, mining, railways, etc.). DC panel by the AC and DC power distribution unit, charging module unit, buck silicon chain unit, DC feed unit, power distribution monitoring unit, the monitoring module unit and insulation monitoring unit. Two: DC-screen works simply, DC panel is to provide a stable DC power supply equipment. DC-screen two-way exchange of electricity through one AC input switching means, to each charging modules. DC screen charging module will enter the three-phase / single-phase AC power is converted to DC power to charge the battery, at the same time to switch on the load, in addition to closing bus through the pressure-relief device power control bus. When the mains power failure or abnormal discharge from the battery emergency power supply; DC panel system of each monitoring unit basis by management and control of the main monitor, via the communication line to each base monitoring unit collected information to the main monitor unified management. DC system main monitor display a variety of information, users can query information and touch screen operation, the system can also access information to a remote monitoring system. DC dismiss the basis of the exchange monitoring, DC monitoring, switch monitoring, you can also configure the insulation monitoring, battery inspection function to the DC system to conduct a comprehensive monitoring. Three: chi Shengda DC panel main features of this product complies with GBT19826-2005 Power Engineering DC power supply General technical conditions. This product complies with DLT5044-2004 Technical specification DC power system design. High reliability: 1, switching power supply modular design, N + 1 hot backup. 2, charging module can be charged hot, on average significantly reduce maintenance time. 3, power bus and control bus can be individually powered directly by the charging module, pressure relief devices by hot backup. 4, low hardware difference between automatic current technology, the module maximum output current imbalance is better than 5%. 5, reliable lightning and electrical insulation, insulation monitoring device capable of real-time monitoring system optional insulation, ensure that systems and personal safety. 6, system design using IEC (International Electrotechnical Commission), UL and other international standards, reliability and security have fully guaranteed. High intelligence: Monitor module using a large-screen LCD display, sound and light alarms. Parameters can be set for each part of the system by monitoring module. Module has smooth adjustment of output voltage and current capabilities, with battery charging temperature compensation. Modern power electronics and computer network technology, provides power system "telemetry, remote, remote, remote tune" the support to achieve unattended. Automatic battery management and protection, real-time automatic detection of the battery terminal voltage, charge and discharge current, and a battery were floating charge for intelligent control, with a battery over-voltage and over-current charge audible alarm. The system uses the built-in insulation monitoring device monitoring, battery testing, grounding line selection, battery activation, silicon chain regulator, the central signal and other functional units, greatly facilitate the users to use; Fourth: DC-screen technology Description Item Technical Specifications AC input voltage range (VAC ) 380V ± 20% frequency range 50Hz ± 10% of rated DC output voltage (VDC) 220/110 voltage adjustment range (VDC) 180-286 Rated current (ADC) 5-200A output current limiting the range of 5% -110% regulation accuracy steady flow accuracy ≤0.5% ≤0.5% ≤0.1% conversion efficiency ripple factor (full load output) ≥94 dynamic response (load 20% -30%) recovery time ≤200μS overshoot ≤ ± 2% dielectric strength 2KVac 1min environmental conditions Noise (1m) ≤55dB Operating ambient temperature -5 ℃ ~ + 45 ℃ Transport and Storage Temperature -40 ~ 70 ℃ Humidity 0-90% non-condensing output overvoltage protection, output current limiting protection, output short circuit protection, over temperature protection module parallel protection, overcurrent cabinet Description: front of the cabinet for the whole glass doors, behind the double doors, elegant appearance; ★ cabinet design for easy equipment installation, maintenance and overhaul and run operations. ★ Dimension has (height X width X depth) 2260 × 800 × 600mm, 2260 × 800 × 800mm two conventional standard and non-standard cabinet can be customized according to the user. ★ cabinet system: the charging cabinet (charging cabinet, the power supply cabinet), battery cabinet. ★ split cabinet system: charging cabinet, the power supply cabinet, the battery cabinet. System components (components) divided by functional units, the system consists of the following components, the basic functions of each component are as follows: ● high-frequency switching rectifier frequency rectifier module to complete the AC / DC conversion, to achieve the most basic functions of the system. ● AC power distribution three-phase AC input power allocated to each frequency rectifier module distribution, its extension to achieve the two-way exchange of input power can automatically switching. ● DC feed DC bus voltage is assigned to each channel DC output circuits through distribution. ● silicon chain regulator unit rectifier output voltage and battery voltage step-down control voltage output within a stable range. ● monitoring unit means to manage the entire system, man-machine dialogue to achieve the window, mainly for battery management, system background remote control. By monitoring device, the various analog AC, DC, the amount of expansion, a variety of switch signal acquisition and analysis processing, sound and light alarms. ● Battery inspection for cell voltage monitoring and alert, I provide battery inspection device and battery inspection unit; detect 19 and 120 single cells. ● insulation testing of bus and fed a branch of the insulation condition monitoring, generates an alarm signal, the data submitted to the monitoring module system displays detailed alarm information in PCU.
