Direct Current power supply system, DC battery charging cabinet

1.Hydropower station, power plant, substation 2.Protection and measuring control system 3.DC switchgear.

   Charging moudle & discharging are combined in a machine cabinet, generally equipped with 3 to 6 charging modules of which can be chosen based on customer demands; it is also equipped with battery cabinet according to user demands. The charging and feeding integrated system can be used in  substation with 110KV or below, and other switch station and customer substation conforming with equal technique demands.

The main characteristics:

1. Integrated design, charge and feed combined with together in a  cabinet.

2. charging module capable of hot-plug online, online maintenance, and easy and convenient;

3. providing dual-circuits alternating-current input interface, capable of accomplishing dual-circuits AC input   automatic switching and locking;

4. providing 31, 33, 35 wiring plans so as to meet the demands in different occasions:

     a. 31 wiring plan: single battery pack, single-bus not sectionalizing, no voltage-reduction set, single charging module capable of outputting single voltage;

     b. 33 wiring plan: single battery pack, single-bus not sectionalizing, equipped with voltage-reduction set, single  charging module capable of outputting single voltage;

     c. 35 wiring plan: single battery pack, single-bus not sectionalizing, equipped with voltage-reduction set, single charging module capable of outputting through double different voltages;

 5. machine cabinet equipped with C and D level lightning protection components: C level lightning protection discharge capacity is 40KA, while D level lightning protection discharge capacity is 8KA;

 6. the system has function of monitoring; grading centralized-distributed control system which is composed of a monitor module, a distribution monitor plate and a charging module equipped with monitor inside and other components,capable of managing and controlling the power system;

7.  has functions of tele-control,tele-metering, tele-signaling and tele-adjusting, which can realizes unmanned operation.

8. large-screen LCD display, sound and light alarm, improve data collection and monitoring, smooth function of adjusting the output current and voltage, automatic battery management, open-interface design with strong communication.
