1. Product Introduction of The GZDW Microcomputer Controlled High Frequency Switch DC Power Cabinet
Working principle of product system:
The GZDW microcomputer controlled high frequency switch DC power cabinet: Two lines of mains power are input into one line of AC through AC switching to supply power to each charging module. The charging module converts the input three-phase AC into DC to charge the battery and supply power to the load of the closing bus. In addition, the closing bus supplies power to the control bus through the step-down device. Each monitoring unit in the system is managed and controlled by the main monitoring unit, and the information collected by each monitoring unit is sent to the main monitoring unit for unified management through communication.
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 connected to the remote monitoring system. In addition to basic units such as AC monitoring, DC monitoring and switching value monitoring, the system can also be configured with functional units such as insulation monitoring and battery patrol inspection to comprehensively monitor the DC system.
