摘　　要：提出了一种将"场"和"路"相结合的方法用于计算220 kV MOA带电测量相间干扰问题。并运用ANSYS Maxwell和EMTP软件联合仿真计算加以验证,为MOA在线监测减小相间干扰提供了理论依据和切实可行的办法。仿真计算结果显示,A相和C相受干扰影响比较明显,而B相幅值和相位变化相对较小。A method combined with "field" and "circuit" is proposed to calculate the interphase interference of 220 kV metal oxide arrester. It is verified by the joint simulation with ANSYS Maxwell and EMTP, which provides a theoretical basis and a practical way to reduce interference effects. The simulation computation results show that the interference effect on phase A and phase C is more obvious, however the amplitude and phase changes of phase B are relatively small.
