特高压串联电容器用国内外PP膜性能对比试验研究

Contrastive Test on Domestic and Foreign Polypropylene Films Used in UHV Series Capacitors

通过对中国首条特高压串补装置中串联电容器的研制过程所做的试验研究,包括国内外PP膜的理化、电气性能,电容器元件的击穿电压,产品多项特殊耐电压试验研究,得出了国外膜和国内膜及国外膜和国内膜浸渍C101D或浸渍M/DBT没有规律性差别的结论。

By the experimental study of series capacitors used in the first ultra high voltage（UHV） series compensation installation in China, including the physic-chemical property, electrical performance of domestic and foreign polypropylene films, the element breakdown voltage and the special withstand voltage tests of the series capacitors, the conclusion is obtained that there is no regularity difference between the domestic and foreign polypropylene films and the films impregnated C101 D or M/DBT.
