摘要
电力电容器的介质结构通常采用固体介质和液体介质组合的方式。由于压紧系数的不同,会导致组合介质的介电常数发生变化。本文通过对组合介质介电常数和元件电容量计算公式的分析,得出了不同介质结构情况下压紧系数变化与组合介电常数之间,以及元件电容与压紧系数之间的关系,对电容器的设计起到一定的指导作用。
The combined dielectrics of solid and liquid are used in power capacitor usually. Due to different pressing coefficient, the dielectric constant of combined dielectrics will be changed. Based on analyzing the computations of combined dielectrics and component capacitance in this article, the relationship between dielectric constant of combined dielectrics and pressing coefficient in various di- electrics structure, and the relationship between component capacitance and pressing coefficient are obtained and will have some guidance to the design of power capacitors.
