| 摘 要： | 为了研究局部放电信号在变压器绕组内部的传播过程,建立了变压器线圈绕组的多导体传输线模型。以40匝单层绕组为特例,根据绕组的轴对称性,建立二维等效有限元模型。考虑绕组核心材料为空心、铝心和铁心的情况,分别采用静电场和时谐磁场模型计算变压器绕组的电容、电感、电阻分布参数。对于频变参数,选取多个频率点进行时谐场计算。在求解过程中,重点考虑了趋肤效应的影响。参数计算的结果同实测的结果基本吻合,计算方法对于研究局部放电(PD)脉冲在电力设备中的传播特性有十分重要的意义。 |

| Abstract: | In order to investigate the propagation process of partial discharge pulses in transformer winding,a simulation model of 40-turn single-layer winding based on multi-conductor transmission line theory is established.The core material of the winding is regarded as hollow,iron and aluminum respectively.According to the symmetry of a winding,a 2D equivalent finite element model is set up in ANSYS environment.In the process of calculation,the skin effect is taken into consideration.The frequency-dependent parame... |
