摘要
为了研究在陡波前、高冲击电压作用下,脉冲变压器(PT)锥形绕组中的特快速暂态电压分布特性,文中建立了基于多导体传输线(MTL)理论的绕组分布参数模型。模型的电气参数通过有限元法(FEM)计算,用频域法计算了在多种情况下绕组的对地电压分布以及匝间电压分布,计算结果表明此模型可对锥形绕组的电压分布进行有效计算,对匝间绝缘设计有一定的参考意义。
In order to study the very fast transient voltage distribution in taper coils of pulse transformer (PT) under high voltage surge of steep front, a distributed model is built based on multiconductor transmission line (MTL) theory. The electrical parameters of models are calculated with finite element method (FEM). Frequency domain analyzing method is used to obtain the voltage to ground and interturn voltage distribution in coil under several different situations. Computational results are presented to illustrate that the model can calculate the voltage distribution in taper coil efficiently, which gives some references for interturn insulation design.
