摘要
本文介绍了特高压换流变压器四种典型绕组结构及电容、电感参数计算方法,通过对实际产品仿真计算得出结论,插花纠结式绕组提高纵向电容效果最优,轴向纠结和轴向内屏绕组其次,螺旋式绕组最差。
This paper introduces four typical winding structures of UHV converter transformer and the calculation methods of capacitance and inductance parameters.By comparing the simulation calculation of actual products,it is concluded that the effect of flower arrangement entanglement winding to improve the longitudinal capacitance is the best,the axial entanglement and axial inner screen winding are the second,and the spiral winding is the worst.
