摘要
文中对电力电容器的元件结构进行了研究,将电容器元件的场强分布归纳为平行均匀电场区域、电极端部折边的平行区域、铝箔卷绕的起始部分及元件两侧的圆弧部分。对不同类型的场强分布情况根据需要借助三维建模软件SolidEdge进行二维和三维建模,采用Quick-Field有限元计算软件和Infolytica软件的ElecNet有限元软件分别对二维和三维模型进行计算分析,通过模拟计算得出了元件最大电场强度的数值和出现的位置,对最大场强出现的区域进行结构优化并重新计算,根据计算和分析的结果,提出电力电容器元件在生产过程中应注意的事项。
In this paper, the structure of power capacitor component is analyzed and electric field strength distribution of capacitor component is classified into, there are four types of distribution about electric field strength could be summarized ： uniform field in parallel area, folding area of electrode tips, start point of aluminum foil winding and both side arc area of the element. To analyses the distribution of these different fields, some software for building models and calculating by finite element method are used. After simulated calculation, the value and position of maximum electric field strength are obtained and renewed by optimization design. According to the results of calcula- tion and analysis, some attentions are pointed out for the procedure of power capacitor producing.
