摘　　要：根据特高压产品结构参数确定了计算运行工况,建立了有限元模型,采用场-路耦合法对特高压变压器的空载励磁电流进行了计算,分析了励磁电流幅值和谐波成分,总结了励磁电流随不同直流电流的变化规律。According to the structural parameters of UHV products, the operation conditions of calculation are determined. The finite element model is established. The no-load exciting current of UHV transformer is calculated by field-circuit coupling method. The amplitude and harmonic component of the exciting current are analyzed. The variation law of exciting current with different DC current is summarized.
