冠军NP38-12(12V38AH)直流屏蓄电池测压线如何连接？

   冠军直流屏蓄电池NP38-12(12V38AH)安装GZDW电源柜时测电池电压线连接在每只电池的(+)正极接线柱上，实时监测电池电压比较容易找出落后的单只电池并及时解决更换。

GZDW dc system ground

(1) fault phenomenon

The central sound signal "alarm bell" rings;"Dc bus fault" light brand bright;The "insulation lowering" indicator light of the insulation monitoring device of the dc system is on;It is extremely unbalanced to measure the positive and negative voltage of dc bus.

(2) fault handling

In order to prevent one point of grounding and another point of grounding, causing protection misoperation or refused to move, or cause bipolar grounding short circuit, burned out the battery, it must quickly eliminate the dc system point of grounding fault.Finding a way to ground,

The principles and sequence are as follows:

1, find the method of the ground.The instantaneous power failure method is adopted to find the connection point, that is, the switch of a certain dc feeder is pulled off instantaneously, and the switch is closed quickly (the cut-off time does not exceed 3s).If the ground signal disappears and the indication of ground voltage of each pole is normal, the grounding point is in the circuit.
