电压以当前额定电压为基准,电流变比是以
1A
为基准,出厂时根据用户的量程要求,确定合适的
仪表量程,在外部输入此量程的信号,若电流变比
都为“100”,则仪表显示 100.0A,在设定了对应的
变比后,仪表将显示对应的数据。用户不得自行改
变信号的输入大小。如用户定了 100A/75mV 仪表,
到了工作现场发现电压变送器为
500A/75mV
,电流
变比由
100
改为
500
,但需确定直流变送器的输出
信号不得发生改变,此例中为
75mV
。
The voltage is based on the current rated voltage,
and the current transformation ratio is based on 1A.
According to the user's measurement range, the
appropriate meter range is determined at the factory,
and the signal of this range is input externally. If the
current change ratio is “100”, then the meter displays
