1： Brief Introduction of DC Panel Small System
Name: microcomputer DC screen 1.6m small system
The 1.6m DC panel small system is designed by Yuexing Power for small capacity systems; Suitable for small size switch The station, small user substation and system adopt the integrated design idea, which consists of rectifier module, monitoring module, step-down unit, power distribution unit and Battery Installation box composition; It has the characteristics of small size, simple structure and independent system; The monitoring module uses LCD Chinese menu display to improve the system monitoring and battery automation management functions. It has four remote interfaces to connect with the automation system, provides two communication interface options of RS232 and RS485, and provides three communication protocol options of RTU, CDT, and MODBUS.
2： Operating principle of DC panel
In short, DC panel is a device that provides stable DC power supply.
The DC screen inputs one AC through two AC switching devices to supply power to each charging module. The DC panel charging module converts the input three-phase/single-phase AC power into DC power to charge the battery and supply power to the closing load. In addition, the closing bus supplies power to the control bus through the step-down device. When the mains power is cut off or abnormal, the battery will discharge for emergency power supply;
Each basic monitoring unit in the DC screen system is managed and controlled by the main monitoring unit, and the information collected by each basic monitoring unit is sent to the main monitoring unit for unified management through the communication line. The main monitoring displays various information of the DC system. Users can also touch the display screen to query information and operation. The system information can also be accessed to the remote monitoring system.
In addition to the basic AC monitoring, DC monitoring and switching value monitoring, the DC panel can also be configured with insulation monitoring and battery patrol inspection functions for integrated monitoring of the DC system.
3： Functional characteristics of DC panel small system
● It is suitable for the system with 40AH/220V, 6 high H/110V and below.
● The module, monitoring unit and step-down unit all adopt the hot plug structure, which is convenient for installation and maintenance.
● Three 2.0A/220V and 4.0A/110V natural cooling modules can be installed.
● The step-down unit has the function of automatic silicon chain step-down, with large current of 2A and impulse current of 30A/0.5S.
