ZHCL-2 DC system data collection module manufacturer will show you the basic working principle of DC system


The manufacturer of ZHCL-2 DC system data collection module tells you that the DC system is a very important part of the substation, and its main task is to provide power for relay protection devices, circuit breaker operations, and various signal circuits. The manufacturer of ZHCL-2 DC system data collection module tells you whether the normal operation of the DC system is related to the correct operation of the relay protection and circuit breaker, which will affect the safe operation of the substation and the entire power grid.

1. When the AC input is normal
The manufacturer of ZHCL-2 DC system data collection module tells you that when the AC input of the system is normal, one of the two AC inputs is selected by the AC switching control circuit, and power is supplied to each charging module through the AC power distribution unit. The charging module converts three-phase AC power into 220V or 110V DC, which is isolated by a built-in isolation diode inside the charging module and then output. On the one hand, it charges the battery and on the other hand provides normal working current to the load.
The manufacturer of ZHCL-2 DC system data collection module tells you that the monitoring part adopts a centralized and distributed way to monitor and control the system. The operating parameters of the charging cabinet, the power feeding cabinet, and the operating parameters of the charging module are collected and processed by the data acquisition module, and then through serial communication The processed information is reported to the monitoring module, and the monitoring module will display it on the LCD screen after unified processing. The manufacturer of ZHCL-2 DC system data collection module tells you that the system can be set and controlled through man-machine interactive operation at the same time, and remote monitoring can be connected if necessary. The monitoring module can also perform equalization/floating charge control and current limiting control on the charging module to ensure the normal charging of the battery and extend the battery life.
2. When the AC input is out of power or abnormal
The manufacturer of ZHCL-2 DC system data collection module tells you that during normal floating charge operation, when the AC input is out of power or abnormal, the charging module stops working. This is because the battery continuously supplies power to the load through the silicon chain system. The monitoring module monitors the battery voltage and discharge. Time, when the battery is discharged to the set undervoltage point, the monitoring module alarms. After the AC input returns to normal, the charging module charges the battery.
