摘要

列举了有外熔断器电容器、集合式内熔丝电容器和架构式内熔丝电容器3种类型不平衡电压保护定值的计算方法

并强调3种计算不能混淆;架构式内熔丝电容器组不平衡电压保护定值不同于外熔断器电容器

也不同于集合式电容器

将外熔断器电容器的计算结果用于内熔丝电容器

一旦发生事故

定会造成事故的扩大;在此通过寻求正确的计算方法

将全部内熔丝电容器的不平衡电压保护定值进行修正

从而保证了整体电容器组安全稳定运行。

Abstract

This article lists the calculation methods of such three types of protection setting of the unbalance voltage as the capacitor with fuse for the external protection

the capacitor with assembled internal fuse and the capacitor with structure internal fuse

and stresses that the three calculations can not be confused;The unbalance voltage protection setting values of above three types are different each other.The calculation result of the capacitor of outer protecting fuse is applied in the capacitor of inter protecting fuse can cause accidental expansion if accident taking place.This article seeks the correct calculation method and amends the protection setting of the capacitor of outer protecting fuse

so to ensure safe and stable operation of complete capacitor banks.
