摘要
根据变压器绕组的实际结构特点，建立了绕组轴向振动数学模型，研究了变压器短路时绕组轴向振动的非线性特性，分析了不同绕组预紧力下线饼轴向位移量、绕组对端压板的作用力随短路电流。
Based on the actual structure of transformer windings, a mathematical model on axial vibrations in transformer windings is developed, and it is applied to study the axial nonlinear vibration characteristics of windings. The relationships between coil axial displacements, winding forces on clamping plate and short circuit currents,tapping change are analyzed under different levels of axial precompression.
