摘要
本文分析了引起电容器发热的主要因素以及发热对电解电容器主要性能的影响,并进一步对最大允许温升的限制和常用冷却措施的冷却效果进行了分析,给出了估算温升的方法,提出了抑制温升的有效措施。
This paper analyzes main factors that heat of capacitors and impact of main charactaristics of electrolytic capacitors from heat- ing,moreover gives an analysis of limits on maximum permitted temperature rise and effect of common cooling measures.This paper al- so gives a method to calculate the temperature rise and propose efficient measures to restrain the temperature rise.
