摘要

自愈性能是金属化薄膜电容器的一项重要参数指标

良好的生产工艺能够有效地改善金属化薄膜电容器的自愈性能。目前国内主要是采用高频脉冲电流法来分析自愈

本文将采用另外一种测试方法

即声压测试法

主要是运用声压矩阵麦克风定位的原理

判断自愈及方位

研究生产工艺参数的改变对元件自愈的影响

为生产工艺的改进提供依据。

Abstract

Self-healing performance is an important parameter indicator of metallized film capacitor and a good production process can effectively improve the self-healing performance of metallized film capacitor.At present

the high-frequency pulse current method is mainly used in China to analyze self-healing.However

the other test method

namely

the sound pressure test method

will be used in this paper

which mainly uses the principle of sound pressure matrix microphone positioning

judges self-healing and orientation and studies the impact of the change of production process parameters on component self-healing so to provide a basis for improvement of the production process.
