摘　　要：为了控制分裂式变压器输出绕组间磁耦合程度,从分裂式变压器输出绕组间的耦合系数定义和测量方法出发,通过理论推导得出了输出绕组对称分布结构的分裂式变压器短路阻抗与耦合系数的关系,从而找到了一种通过控制短路阻抗来控制耦合系数的方法,并通过样机试验数据验证了该方法的可行性。In order to control the degree of magnetic coupling between the output windings of a split transformer,starting from the definition and measurement method of the coupling coefficient between the output windings of the split transformer,the relationship between the short-circuit impedance and the coupling coefficient of the split transformer with a symmetrical distribution structure of the output winding is theoretically derived.A method of controlling the coupling coefficient by controlling the short-circuit impedance is found,and the feasibility of this method is verified through prototype test data.
