新型SVCT系列磁调制电压传感器

Novel SVCT Series of Fluxgate Voltage Sensor

通过磁性材料研究确定高导磁环镍铁合金(1J77)的B-H曲线,分析其在方波电压激励下的工作过程,论证其有较快的响应时间。介绍SVCT系列磁调制电压传感器在直流、低频和高频测量下不同的工作原理,并以SVCT.1000B产品为例进行分析。该产品性能参数满足实际应用需求,同时已经通过常规环境可靠性和电磁兼容可靠性试验。

High magnet-conductive Ni-Fe alloy coil（1J77） was researched, B-H curve of which was defined; by analyzing the operation process under square wave voltage of 1J77, it was proved have fast response. Working principle under the different input situations of DC, low and high frequency of SVCT series fluxgate voltage sensor was introduced by taking SVCT. 1000B product as example. The product satisfied actual applying required, and passed normal environment and EMC reliability test.
