摘要

本文研究了直流金属化薄膜电容器制造的基本原理，即基底膜、浸渍剂和金属化模式的选择。在生产过程中对电容器进行对比测试，并在热应力和电应力下加速老化，使电容器的寿命从薄膜类型、浸渍介质和电极配置的最佳选择中提高两个数量级。膜的选择使相对寿命增加:>10倍/倍/寿命;低损耗介质液体>2/spl倍/理论寿命;>6/spl次/寿命的金属化膜电极的成功设计。

High energy density capacitor development at ABB Power T&D

This paper investigates the fundamentals involved in the manufacture of d.c. metallised film capacitors, namely the choice of base film, impregnant and metallisation pattern. Comparative testing of capacitors during production and on accelerated ageing under thermal and electrical stress enable capacitor life to be enhanced by two orders of magnitude from the optimum selection of film type, impregnant medium and electrode configuration. The relative life increases being: >10/spl times/life time due to film selection; >2/spl times/theoretical life for low loss dielectric liquids; >6/spl times/life for the successful design of metallised film electrodes.
