| 摘要:本课题提供了全新的纤维素纤维电解电容器纸（以下简称电解纸）分类方案，提出并验证了在吸液性能评估模型中增加非极性模拟液的必要性，讨论了纸对电解液的亲和性与成品电解电容器等效串联电阻（ESR）的内在联系；分析了孔隙率大的电解纸需要关注防短路性能的原因及用透气度反映低紧度纸的防短路性能的可行性。将本课题的研究成果融入了对IEC 60554-3-4:1979的修订提案中，建议重新构建电解纸的分类体系；将吸水性能的考核延伸到吸液性能；对低紧度的薄纸引入透气度指标；增加考核铁微粒子、抗张强度，以及对中、高压电解纸考核击穿强度。 |
| Abstract:A new classification scheme for cellulose electrolytic capacitor paper （ECP） was provided in this paper. The necessity of adding non-polar simulants to the absorption performance evaluation model was proposed and validated. The intrinsic connection between the affinity of paper for electrolyte and the equivalent series resistance （ESR） of the finished electrolytic capacitor was discussed. The reasons why electrolytic paper with large porosity needed to be concerned with short-circuit prevention performance， and the feasibility of using air permeability index to reflect the short circuit resistance of low density paper were analyzed. Incorporating the findings of this paper into the proposed revision of IEC 60554-3-4：1979， the classification system of electrolytic paper will be reconstructed； the assessment of water absorption performance will be extended to liquid absorption performance； the air permeability index for thin paper with low density will be introduced； the assessment of iron microparticles and tensile strength， and assess breakdown strength for medium and high voltage electrolytic paper will be added. |
