摘要
阐述了反射式全光纤电流互感器的工作原理,分析了互感器解调系统输出信号的特性,由此设计了全光纤电流互感器的解调系统方案,给出了一种FPGA+MCU的实现方法,研制了全光纤电流互感器的解调系统,并进行了测试验证。测试结果表明,解调系统能够对全光纤电流互感器交流及直流电流信号进行解析,说明解调系统满足全光纤电流互感器的功能要求。
The working principles of the reflection of an All- fiber optical current transformer（FOCT） were described, the characteristics of transformer out- put signal demodulation system were analyzed, and on this basis, an all - fiber optical current transformer de- modulation system were designed. Furthermore an FPGA＋MCU implementing method was provided and a demodulation system for the all -fiber optical current transformer was developed. Test results showed that the demodulation system could parse the all - fiber op- tical current transformer AC and DC signal demodula- tion. Therefore, the verification system can meet the requirements for application in all - fiber optical cur- rent transformers.
