The force is then used as a distributed load to obtain the winding displacement distribution in the analysis of axial stability of windings,in which the bearing material attribute and installation characteristic are considered.
针对电力变压器绕组轴向稳定性的计算方法中,"质量—弹簧—阻尼"集中参数法无法考虑绕组的弯曲变形和垫块的数量、宽度对轴向稳定性影响的问题,采用有限元的方法计算绕组各线饼短路情况下的电动力,以此作为绕组轴向振动的力载荷分析绕组的轴向稳定性,得出了绕组各线饼的位移分布,在绕组轴向振动分析中既考虑了垫块的材料属性,又兼顾了垫块沿周向分布的特点。
Recent achievements in the field of the axial stability of electric power transformer windings are summarized in this paper.
