摘　　要：通过理论分析互感器的气隙大小与抗直流能力的等值关系,并对互感器的磁滞回线进行模拟仿真,建立含气隙铁心的电流互感器的仿真模型,根据仿真结果验证了含气隙互感器的抗直流有效性。在此基础上,建立起双铁心电流互感器的仿真模型,验证其抗直流能力和基波准确度。Theoretical analysis of the equivalent relationship is between the air gap length and the anti-DC capability of air gapped core current transformer. And simulate the hysteresis loop of the air gapped core current transformer, establish a simulation model of air gapped core current transformer. According to the simulation results, the anti-DC effectiveness of air gapped core current transformer is verified. On this basis, a simulation model of the two cores current transformer is established to verify its ability of antiDC and the accuracy of the fundamental wave.
