Introduction:
The rectifier adopts a high-frequency switch resonant high-efficiency intelligent power module, intelligent digital technology, independent current sharing, temperature controlled fan, complete protection functions, high cost-effectiveness, complete system detection, convenient setting, and intelligent management. According to the operation and management diagram of the battery power system, the monitoring module completes automatic control and management of leveling and floating, and is equipped with electric temperature compensation function. The monitoring module provides power standard RUT/CDT/MODBUS protocol, and can form various network management systems with computer or integrated automation through RS232/RS485 or TCP/IP interfaces. The ultra large full Chinese blue touch screen display makes operation more convenient, maintenance convenient, complete set strong, and pollution-free. Suitable for unmanned substations.
Technical characteristics
1. Intelligent battery charging and discharging management: Based on changes in charging voltage, current, and environmental temperature, the device automatically selects constant current, uniform charging, and floating charging methods to meet the requirements of the battery charging curve, prevent undercharging or overcharging of the battery, and keep it in a full capacity state. The battery activation function can also be activated to extend the service life of the battery.
2. Multiple communication methods: The device provides an RS485/232 communication interface for data transmission with the upper computer, using various communication protocols such as CDT. Complete the "four remote" functions of the DC power supply system and achieve unmanned substation operation. GSM short message platform and network methods can also be used for wireless or wired communication
3. Friendly human-machine dialogue: The monitor of the device adopts a large screen, wide temperature, blue backlight, and Chinese display. The operating parameters, status, and fault information of the DC system can be displayed on the screen. The system related parameters can be set through the keyboard, and the operation status of the device is clear at a glance, making it extremely convenient to operate
4. Reliable configuration: The device is equipped with domestic and foreign high-quality batteries, and the charging module adopts a high-frequency switching power supply N+1 redundant parallel combination method. AC dual power input, equipped with C-level lightning arrester, can effectively absorb overvoltage generated by lightning strikes, ensuring system safety.
5. Complete detection function: The device has multiple detection functions such as multi-channel AC/DC parameters, battery voltage, insulation branch positioning, feed circuit status, module faults, temperature, etc. If there is an alarm situation in the device, it can send out an alarm message. In case of a serious alarm situation, the device will automatically enter the emergency processing state
6. Perfect protection function: The device has AC input undervoltage, overvoltage, and phase loss; Output undervoltage, overvoltage, output voltage limiting, current limiting; Multiple protection functions such as module overheating and temperature. Especially the power module has a short circuit recovery feature inside, even if the module output end is in a short circuit state for a long time, it will not be damaged. After the fault is eliminated, the module can automatically resume operation.
