1.3 信号采集电路

信号采集电路负责采集电流信号、频率信号和零序电流信号。其中，电流信号采用互感器隔离输入，将交流信号抬高后送入CPU进行软件差分运算，电流采样电路如图2所示。以A相6.3A规格为例，采用的电流互感器变比为100A：20mA，5P10保护型。该方案电流测量在1.2倍范围内达到0.5S精度，在8倍范围内满足5S精度，而其过载能力按8倍计算，即给互感器加上50.4A电流，通过取样电阻R1的电流为10.08mA，两端电压为0.886V。同时，给采样信号抬高电压UREF=1.2V，使交流信号的幅值大于零，便于A/D采样；在电路的输出端加入限压二极管，使输入电压限制在3.3V以下，能对A/D采样通道起到很好的保护作用。
