Function introduction
GZDW is mainly based on DC power supply: the system consists of DC monitoring unit, AC monitoring unit; feed detection; battery inspection module; rectifier module; DC monitor screen and battery pack.
The main function is to make the electric power grid to be stable, reliable direct current, charging for the battery, and all kinds of DC load power supply, it is the most basic components of the system,
DC monitoring unit is responsible for the detection of DC bus voltage, bus voltage, voltage control, voltage, current, the output of the current Holzer sensor, the range of -5V and +5V DC analog, Holzer sensor using 12V power supply.
AC detection unit: monitoring AC output current; a A, B, C three-phase voltage; two A, B, C three-phase voltage; one way and two way AC contactor control stem node, a road and two State Road 1-5; AC breaker tripping signal.
Feed monitoring unit, 16 way switch quantity; 16 way switch fault detection; 16 way branch leakage current detection. Positive voltage, positive voltage.
Battery checking unit: collected 108 2V lead-acid batteries, battery range 0-3.3VDC, single cell voltage measurement error: less than 10mV
