Air stable 1,3-dialkyl imidazolium based room-temperature molten salts have been extensively utilized for a variety of electrolytes in batteries and capacitor. 作为一类对空气稳定的室温熔盐,基于1,3-烷基咪唑阳离子的离子液体已广泛用作电池和电化学电容器的电解液。
This article introduces the true value measurement of dissipation factor by making use of an air capacitor with gap-variable guard-ring. 本文介绍利用变间隙保护环电容器的损耗特性进行损耗因数的绝对测量(真值测量)和传递。
The voltage coefficient of a standard air capacitor was measured by the designed measuring system. The results and uncertainties under different voltages are given. 用所设计的测量系统实测了标准空气电容器的电压系数,给出了测量结果及不同电压下的不确定度。
The research found that the breakdown voltage and delay time are larger when the air pressure increased, but the trend of the breakdown voltage is not completely synchronized in the charging voltage of the capacitor. 发现气体开关间隙的击穿电压和击穿间隙随充气气压的增加而变大;而击穿电压的变化趋势却不完全同步于主电容的充电电压。
