Effects of aging temperature on performance of medium voltage and high voltage aluminum electrolytic capacitors

本文选择了市面上常见的3种中高压铝电解电容器,并在90~110℃中选取5个温度进行手工高温老练试验。通过对电容量、损耗角正切和漏电流3个性能参数的分析,评估了电容器性能的稳定性和老练效果。研究结果表明,在90℃和105℃的高温老练条件下,电容器的性能有显著提升。特别是在105℃的高温老练条件下,CD11GS型250 V电容器和CD11MA型400 V电容器经过高温老练后展现出最佳性能。而对于CD11GS型450 V电容器来说,在90℃的高温老练条件下表现出最佳性能。这些研究结果表明,高温老练温度对中高压铝电解电容器的性能有显著影响。这些发现对于改善电容器的性能稳定性和优化老练工艺具有重要意义。此外,这些研究还为有关中高压铝电解电容器的老练工艺提供了实验基础和性能参数分析方法。

This study selected three mesohigh voltage aluminum electrolytic capacitors which conducted manual aging tests at temperatures ranging from 90℃to 110℃.Capacitance,dissipation factor,and leakage current were measured before and after the high temperature storage test to assess the stability of capacitor performance and the effect of aging.Capacitors performed best under high-temperature aging conditions of 90℃and 105℃.CD11GS 250 V and CD11MA 400 V capacitors,in particular,showed the greatest performance improvement after high-temperature aging at 105℃.On the other hand,CD11GS 450 V capacitors performed best after high-temperature aging at 90℃.The results indicated that high-temperature aging had a significant impact on the performance of high-voltage aluminum electrolytic capacitors.These findings were crucial for optimizing aging processes and improving the stability of capacitor performance.Furthermore,this study offered an experimental foundation and performance parameter analysis method for investigating the aging process of mesohigh voltage aluminum electrolytic capacitors.
