摘　　要：针对传统微型电流互感器在一次绕组存在直流分量时传变特性变差,分析了直流分量导致传统微型电流互感器失准的机理,研发了抗直流分量微型电流互感器。实验证明该抗直流分量微型电流互感器具有较好的抗直流性能,能达到0.5级测量精度。Aiming that the transmission characteristic of traditional miniature current transformer became worse when there was DC component in primary winding. The misalignment mechanism of traditional miniature current transformer caused by DC component was analyzed. The anti-DC component miniature current transformer was developed. The experiment proves that the miniature current transformer with anti-DC component has good anti-DC performance and can achieve 0.5 level measurement accuracy.
