摘要

自愈特性作为反应金属化膜电容器质量的一项重要参考指标，如何有效地通过各类测试方法实现电容器元件的自愈性能考核，最大限度筛选出合格的电容器元件是电容器生产商最关注的问题，本文结合实际生产需求，通过电测法实现自愈次数有效性分析，从不同维度提出可量化的自愈特征参数并进行了量化考核分析，确定了不同维度的量化指标作为电容器元件全检策略的质量评价依据。

Abstract

As a critical quality indicator for metallized film capacitors

how to effectively realize the self-healing performance evaluation of capacitor components through various test methods and screen qualified capacitor components to the greatest extent is the most concerned problem of capacitor manufacturers. In this paper

the effective analysis of the self-healtign number is achieved in combination with the actual production demand and also through electrical measurement method. The quantitative self-healing characteristic parameters are proposed from different dimensions

and the quantitative assessment analysis is performed. The quantitative indicators of different dimensions are determined as the quality evaluation basis of the full inspection strategy of capacitor components.
