摘要: 为了研究脉冲变压器锥形绕组在脉冲电压作用下的电压分布特性，采用多导体传输线方法，根据实际脉冲变压器锥形绕组的结构，建立了电气参数有限元简化计算模型及等效多导体传输线分析数学模型，以此模型计算了锥形绕组在脉冲电压激励下匝间的电压分布。计算结果表明，此模型可对脉冲变压器锥形绕组的电压分布进行有效计算，对绕组匝间绝缘设计有一定的参考意义。Abstract: In order to study the voltage distribution on the pulse transformer's conical windings, according to the structure of the actual pulse transformer's taper windings, the finite element model and equivalent circuit were built based on the multi-conductor transmission line theory. Using the model and circuit, the voltage distribution between the coils on the pulse was calculated. Computational results are presented to illustrate that the model can be used to calculate the voltage distribution in taper coil efficiently, which gives some references for the design of inter-turn insulation.
