Dc panel 40AH/DC220V is a kind of DC power supply designed for high frequency switch of high voltage cabinet in highway distribution room.
Dc screen, the full name of DC power operating system, the general name is intelligent maintenance-free DC power supply screen, referred to as DC screen, its general model is GZDW. This equipment is suitable for 10~500kV substations, power plants and high-rise buildings, residential areas and other distribution rooms, as well as small self-provided power plants. The main function of DC screen is as high voltage switch, relay protection, automatic device, control system, etc. Operation, control power supply and accident lighting power supply. In addition, it can also be applied to other places that need DC power supply, such as petrochemical, mining, railway and so on.
The DC screen consists of a number of units, including AC and DC distribution unit, charging module unit, step-down silicon chain unit, DC feed unit, distribution monitoring unit, monitoring module unit and insulation monitoring unit. These units work together to ensure that the DC panel can provide a stable and reliable DC power supply.
Working principle: The DC panel supplies power to each charging module through the input of two mains through the dual AC switching device. The charging module converts the input three-phase/single-phase AC to direct current to charge the battery and power the closing load at the same time. When the mains power is cut off or abnormal, the battery discharge provides emergency power.
Monitoring and management: Each basic monitoring unit in the system is managed and controlled by the master monitoring, and the information collected by each basic monitoring unit is sent to the master monitoring and unified management through the communication line. The main monitor displays all kinds of information of the DC system, and users can also query information and operate by touching the display screen. The system information can also be connected to the remote monitoring system to achieve comprehensive monitoring and management.
Main features: Yuexing Power brand 40AH DC in addition to the basic AC monitoring, DC monitoring, switching quantity monitoring, can also be configured insulation monitoring, battery inspection functions, used for comprehensive monitoring of the DC system.
In summary, 40AH/DC220V DC screen is a kind of equipment designed for high voltage cabinet high frequency switch of highway distribution room, with efficient, stable and reliable characteristics, suitable for a variety of occasions that need stable DC power supply
