摘　　要：智能电容器包括无功补偿综合模块与电力电容器2大部分,各部分又分别由其子模块构成,具有实时显示、操作简单、过零投切电容器、保护预警、可靠通信等功能要求。在电容器投切方面,现有投切方式有延时投切、瞬间投切与混合投切等,其中,投切开关是跟踪负荷变化的最主要环节,对此文章基于对机械投切开关及晶闸管投切开关的分析,提出一种集2者优点于一体的智能化低压无功补偿复合开关装置,在解决合闸涌流、过电压与高次谐波等问题方面优势明显,补偿准确,亦有很高的精度。Intelligent capacitor has reactive compensation integrated module and power capacitor two parts,each part is made up of it sub-modules.The functions of intelligent capacitor are real-time display,simple operation,zero-crossing switching capacitor,protect warning and reliable communication.Capacitor switching ways conclude delay for,moment for and hybrid for,hurl-slices switch is the most important link to tail after the load change.Withal,the paper proposes an intelligentize low-voltage reactive compensation combination switch device based on the mechanical switch and thyristor switch analysis,it has obvious advantages in switching inrush current,over-voltage,ultra-harmonics and other aspects,compensation precision is high.
