- Overview of GZDW DC panel
DC panel is the abbreviation of DC power supply operating system. The general name is intelligent maintenance-free DC power panel, referred to as DC panel, and the general model is GZDW. DC panel is suitable for 10-500kV substations, power plants and distribution rooms of high-rise buildings, residential areas, etc., as well as small self-contained power plants, as the operation, control power supply and emergency lighting power supply for high-voltage switches, relay protection, automatic devices, control systems, etc. It can also be used in other places that require DC power supply (such as petrochemical, mining, railways, etc.). The DC panel consists of AC and DC distribution units, charging module units, step-down silicon chain units, DC feed units, distribution monitoring units, monitoring module units and insulation monitoring units.

- System Features
- The system is fully modularized, simple, intuitive, and easy to group. Multiple high-frequency switch charging modules can be operated in parallel.
- N+1 hot backup;
- Ultra-wide voltage input range, strong grid applicability, and can be used in places with relatively harsh environments;
- The charging module can be plugged in and out with power, and online maintenance is convenient and fast;
- Intelligent control of the charging module, smooth adjustment of output voltage and current; autonomous current balancing, good stability, and high current balancing accuracy (maximum output current imbalance is less than 3%);
- The system design adopts international standards such as IEC International Electrotechnical Commission, UL, EN, etc., and reliability and safety are fully guaranteed;
- The monitoring system adopts Touch screen or large screen LCD Chinese character display, friendly human-machine interface, intuitive and convenient operation;
- The parameters of each part of the system can be set through the monitoring module, with a friendly interface and easy operation;
- Open interface design, with powerful communication function, it is very convenient to connect with the substation RTU device or the power plant computer monitoring system DCS;
- The three-level distributed monitoring system realizes telemetry, remote control, remote signaling, remote adjustment, and unmanned operation of the power system;
- Automatic battery management and protection, real-time automatic monitoring of the battery terminal voltage, charge and discharge current and control of the battery equalization and floating charge conversion, with battery over/under voltage and charging overcurrent sound and light alarm and temperature automatic compensation function.
