摘要
介绍了变压器绕组的等值电路模型中电容和电感参数的计算方法。针对绕组等值电路参数分别利用解析公式法和有限元法对连续式绕组的电容和电感值进行了计算,其中详细介绍了利用有限元软件ANSYS Maxwell得到电容、电感参数的过程。仿真计算结果表明,解析公式法计算精度低于有限元法,并且只能用来求解正常绕组的等效电路参数,不适用于变形绕组。
This article describes the calculation method of the equivalent circuit model of transformer winding capacitance and inductance parameters. For winding equivalent circuit parameters are using analytical formula method and ifnite element method for capacitance and inductance values continuous winding were calculated, which describes the use of ifnite element software ANSYS Maxwell obtained capacitance, inductance parameters of the process. The calculation results show that the calculation accuracy is lower than the ifnite element method, and can only be used to solve the equivalent circuit parameters of the normal winding, not suitable for the deformation windings.
