Electronic charging indicating relay 电子充电指示继电器
The charger shall give an alarm signal upon failure initiated by either an under-voltage relay or a zero charging current relay.
充电器应发出警报信号后没有任何一方发起一个欠压继电器或零充电电流继电器。
In this case, the series resistor should be placed as close to the relay as possible to limit the current when charging the cable capacitance.
在这种情况下，串联电阻就应该尽量靠近继电器，以限制电缆电容充电时的电流。
During the intermediate repair the charging system of No1 blast furnace was modernized and PLC control system replaced relay control.
在1号高炉中修时对上料系统进行了改造，用P LC控制取代继电器控制。
