The design of Renda color touch DC screen screen refers to the Ministry of Electric Power's "DL/T5044-2004", "JB/5777.2-2002" and "JB/5777.3-2002" and other related technical standards, which can reliably meet the power supply needs of DC control power supply and high and low voltage switch switching and closing under normal or abnormal conditions of the transmission and distribution system. It is widely used in DC operation power supply requirements of substations below 500KV and power plants below 600,000KW.
Renda color touch screen DC screen adopts building block structure design, the system contains: system main monitoring, AC monitoring unit, DC monitoring unit, switching monitoring unit, etc., and can also be equipped with battery inspection unit and insulation monitoring unit as needed.
Renda color touch DC screen is widely used in factory workshops, power plants, metallurgical monitoring rooms, etc.
System Features:
1. High-frequency switching power supply technology, modular design, N+1 hot backup.
2. Wide voltage input range and strong adaptability of power grid.
3. The charging module can be plugged and unplugged with electricity, and the maintenance is convenient and fast.
4. There are reliable lightning protection and electrical insulation protection measures to ensure system and personal safety.
4. It adopts large-screen touch screen, dot matrix LCD display, CCFL backlight to realize real-time display and operation of full Chineseization.
5. System parameter query and setting can be carried out by clicking the touch screen, and the man-machine interface is friendly, and the operation is simple and convenient.
6. The monitoring system can automatically complete the accurate management of battery voltage, charge and discharge current and temperature compensation to ensure that the battery works in the best state and prolong the battery life.
7. Adopt a distributed monitoring system with microprocessor as the core, modular design, implement all-round monitoring, control and "four remote" of the power supply system, and realize unattended.
8. Real-time monitoring of battery terminal voltage, charge and discharge current, accurate control of battery average charge and floating charge, with battery over-under-voltage alarm, battery over-temperature alarm and overcharge protection and other functions.
9. The system has the management function of battery temperature compensation.
10. A set of monitoring system can be used to manage double battery packs, three charging devices, and bus bar segments to realize independent charging management of double batteries.
