对金属化膜电容器局部放电和自愈放电性能的初步研究

Preliminary Research on Partial Discharge and Self-healing Characteristics of Metallized Film Capacitors

介绍了金属化膜电容器的局部放电和自愈放电特性,分析了两种过程的同异、其间的联系以及其对电容器介质性能的危害。指出对金属化电容器进行局部放电和自愈放电特性的测试是鉴别和改进产品质量的重要手段。

In this paper, the partial discharge and self-healing characteristics of metallized film capacitors were introduced. The differences and associations of the two processes, their interaction and influence on dielectric performance were analysed. It pointed out that partial discharge measurement and self-healing characteristic test for metallized film capacitors were an important method to distin-guish and to improve the quality of products.
