中文摘要：
针对智能电网中直流的检测,设计了反射式和透射式两种光路结构的光学电流传感器,采用不同厚度的永磁薄膜的石榴石磁光材料作为传感器的敏感元件进行直流电流监测实验,以此对传感器的灵敏性与稳定性进行研究。结果表明,以不同厚度的永磁薄膜的石榴石磁光材料作为传感器的敏感元件,两种结构的传感器测量灵敏度均较高,在反射式结构中厚度为2μm的石榴石材料与透射式结构中厚度为1μm的石榴石材料作为敏感元件时,传感器的偏振度变化幅度较小,表明系统的稳定性较好。
英文摘要：
Aiming at the detection of dc current in the smart grid, the reflection and transmission light path structures are designed for optical current sensors. DC current monitoring experiments are performed with permanent magnetic thin films with different thicknesses of garnet magneto-optic material as the sensitive element of the sensor to study the stability and sensitivity of the sensor. The experimental results show that both structures achieves high sensi- tivity with garnet magneto-optic material with different thickness of the permanent magnetic thin films as sensitive ele- ment of sensor; the DOP of sensor has lesser variations with 2 pan garnet material in the reflection structure and 1 μm garnet material in the transmission structure as a sensitive element, which means that the system has good stability.
