摘　　要：对110kV三绕组电力变压器中、低压绕组辐向变形状况与绕组对间短路电抗变化规律进行了研究分析,推导出绕组变形程度和短路电抗变化率之间的函数关系,并通过实例验证了其正确性。The change rule of the radial deformation and short-circuit reactance between windings of 110 kV three-winding power transformer is studied and analyzed. The functional relationship between the winding deformation degree and the change rate of short-circuit reactance is deduced, and its correctness is verified by an example.
