一种新型交流高电压采集电路
摘要：
本实用新型公开了一种新型交流高电压采集电路，包括高压电阻、微型电流互感器、气隙保护器件和二次采样电路，所述高压电阻与所述微型电流互感器的初级线圈串联；所述气隙保护器件连接在所述微型电流互感器的初级线圈的两端之间；所述二次采样电路连接在所述微型电流互感器的次级线圈的两端之间。本实用新型的新型交流高电压采集电路，先将一次的高电压转换成弱电流信号，再对弱电流信号进行采样转换成二次的小电压信号，使得二次电路结构更为简单；实现了一次与二次的隔离；一次与二次之间传递的为电流信号，抗干扰能力强。
摘要（英）：

The utility model discloses a novel exchange high voltage acquisition circuit, including high -pressure resistance, miniature current transformer, air gap protective device and secondary sampling circuit, the high pressure resistance with miniature current transformer's primary establishes ties, air gap protective device connects between miniature current transformer's primary's the both ends, secondary sampling circuit connects between miniature current transformer's secondary coil's the both ends. The utility model discloses a novel exchange high voltage acquisition circuit becomes the weak current signal with high voltage conversion once earlier, samples to the weak current signal and converts quadratic little voltage signal to for the secondary circuit structure is more simple, realized once with quadratic isolation, once and between the secondary transmission be the current signal, the interference killing feature is strong.
