资料介绍

论述了全光纤电流互感器检测和控制原理,以单片FPGA为控制核心设计了全光纤电流互感器信号检测与控制硬件电路,并对关键部件指标和检测控制方法进行了分析和讨论.结合前端光纤电流传感头搭建了全光纤电流互感器装置.经实验测试,其在额定一次电流100A~4000A范围内均实现了0.2S级测量准确度,满足电力电网对电流互感器测量准确度的要求.

The topology and operational principle of fiber optic cmrent transducer are introduced. A signal detection and con- trol hardware circuit for fiber optic current transducer was designed base on a single FPGA, the parameter of key components and control method are analyzed and discussed. Meanwhile ,the experiment equipment was designed using this circuit combined with fiber-current sensor head.. The result shows that it can satisfy the accuracy requirements of the 0.2 S class measuring electronic transducer within range from 100 A to 4 000 A, meeting the electrical power grid for the current transformer measurement accuracy requirements.
