Application of Amorphous Material in Miniature Current Transformer

将铁基非晶磁心应用到小型电流互感器上,研究了铁基非晶磁心对小型电流互感器的性能影响.结果表明,采用了铁基非晶磁心的小型电流互感器,在输入电流为0.2～6.0 A时,互感器的电流误差小于1％,相位差小于0.1°,且稳定性较好.铁基非晶磁心可以作为高精度小型电流互感器磁心.

The Fe-based amorphous cores are applied to miniature current transformer. This paper studied the effect of Fe-based amorphous cores on the performance of current transformer. The results show that, when the input current is 0.2 -6.0 A, for the miniature current transformer which uses Fe-based amorphous cores, the current error is less than 1% ,the phase error is less than 0. 1 °,and it works stably. Fe-based amorphous cores can be used as the cores of high precision miniature current transformer.
