current overload relay 电流过载继电器
If the load resistor was connected directly across the voltmeter input terminals, the current through the relay contacts would cause a voltage drop and the measured cell voltage would be in error.
如果负载电阻被直接连接到伏特计的输入端子，通过继电器触点的电流会产生电压降，测得的电池电压将存在误差。
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。
