变压器绕组的短路电动力分析

Analysis on Short-circuit Rigidity of Transformer Windings

分析了变压器绕组在短路时的轴向受力情况,如绕组高度不等且上下不对称的情况、轴向安匝分布不平衡的情况等,并提出了绕组轴向压紧方面的工艺措施,以保证变压器绕组短路强度和稳定性。

The analysis of axial force behavior when transformer windings undergo a short - circuit are presented. Such as unequal altitude, dissymmetrical up and down of the windings, and axial number of ampere turns distribution is disbalance. The technology method of axial compression are suggested for pledging short - cicuit rigidity and stabitity of transformer windings.
