光纤电子式电流互感器的优化设计

Optimization design of fiber electronic current transformer

新型光纤数字化电子式电流互感器(ECT)是在普通ECT的基础上改进其存在的一些不足,使之精度更高,功耗更低,功能更完善,适用于数字化变电站的要求。文章首先介绍了新型光纤数字化ECT的总体设计,然后分别介绍了组成新型数字化ECT的高压侧数据采集器和低压侧合并单元(MU),最后介绍了新型数字化ECT的供能方案。

Improved on the basis of the ordinary Electronic Current Transformer （ECT） and characteristic of higher precision, lower power consumption and better functions, the novel ECT satisfies the requirements of digital substations. This paper successively introduces its general design, its constituent data collector at the higher voltage side and the Merging Unit（MU）at the lower voltage side and its power supply scheme.
