摘　　要：为合理调试电流互感器元件,研究新型电力系统下无网侧电流互感器结构的校核方法。在交变电流互感回路中,求解无网侧电流负载参数,构建无网侧电流互感器的结构模型。根据电流时延量取值,解析互感电流的结构形态,以此定义校核条件。实验结果表明,依照上述方法调试电流互感器,电流测量值与额定电流值最大差为0.4 A,不会超过也不会明显低于电力系统所规定的额定电流条件,能够使互感器结构较好适应无网侧的电量负荷需求。In order to reasonably debug the current transformer components,the verification method of the grid-side current transformer structure under the new power system was studied.In the alternating current transformance loop,the current load parameters without the grid side were solved,and the structural model of the current transformer without the grid side was constructed.According to the value of the current delay,the structure of the mutual inductance current was analyzed,and the check conditions were defined.The experimental results showed that the maximum difference between the measured current and the rated current value was 0.4 A,which would not exceed or significantly lower than the rated current condition specified by the power system,and can make the transformer structure better adapt to the power load demand of the non-grid side.
