| 摘 要： | 笔者应用有限元软件ANSYS对变压器短路试验模型进行了仿真分析。当撑条取不同弹性模量值时,计算了绕组线饼的变形;通过改变撑条圆周方向尺寸,计算得出了对应4种撑条尺寸的线饼的径向位移;采用短路电流下的载荷对模型进行计算分析,得出的线饼的变形最大值2.62 mm与实测值2.906 mm基本吻合。文中的分析方法可用于大容量变压器的绕组短路强度和径向稳定性分析。 |

| Abstract: | This paper processes simulate analysis of short-circuit test model of transformer,using finite element analysis software ANSYS.The winding and disk deformation is calculated in different elastic modulus value of strip;By changing the size of strip circumferential direction,radial displacement of disk is calculated corresponding to the four strip size;The model is calculated and analyzed in the load of short-circuit test,the maximum deformation 2.62 mm of disk obtained is consistent with actual measured value 2.906 mm.This analysis method in paper can be used for large power transformer winding short-circuit strength and radial stability analysis. |
| Keywords: | power transformer short-circuit test model radial stability short-circuit strength |
