摘要
本文提出了变压器线圈电磁暂态分析的新方法──Ｂｅｒｇｅｒｏｎ法，推导了有互感电路的等值参数和计算公式，叙述了如何形成节点导纳矩阵。实测结果与分析表明，在变压器低压线圈短路时，高压线圈与空心线圈的电感相同。根据计算与实测结果分析，提出了确定等值电路中各项参数的方法。
This paper presents a new method of electro-magnetic transient analysis for transformer windings-the Bergeron's method.The equivalent parameter and calculation formula of circuit with mutual inductance are deduced. Besides,it is narrated how the nodal admittance matrix is formed.The results of practical experiments and analysis show that the inductance of the high voltage winding of a transformer is similar to the inductance of the same winding with air core when the low voltage winding is short-circuited.According to the results of calculations and experiments,determination method for the parameters of the equivalent circuit are presented.
