摘要
通过对圆柱体电容器内部压强进行计算分析,研究提升电容器寿命的方法。首先分析得出,电容器内部层间压强的提高可以减小自愈能量,降低脉冲放电过程中的电容量损失,因此可以提升电容器寿命。其次,提出了电容器内部层间压强的计算模型。试验结果表明: 通过合理的热处理工艺,电容器寿命可提高30%; 当外包膜层数从20层增加到100层时,电容器寿命提高38%。
Abstract
This paper concentrates on the inner pressure in the cylindrical metallized polypropylene film capacitor (MPPFC) winding. Firstly, the influences of inner pressure on self-healing and lifetime are investigated. Lifetime can be extended by inner pressure strengthening. Secondly, an inner pressure calculation formula is presented. Finally, the experimental results show that lifetime can be extended by 30% with rational heat treatment and by 38% when the number of wrapped films increases from 20 to 100.
