桥差保护灵敏度的分析
摘要
大容量电容器组保护的整定值常常很小
保护的灵敏度较低。为增加保护灵敏度常常采用桥式不平衡电流保护。通过分析桥差保护的灵敏度
得出桥差保护最大灵敏度的接线方式。
Abstract
The setting value of protection of the large capacity capacitor banks was usually low
and had less sensitivity.The unbalance bridge protection was adopted for sensitivity.This paper introduces the connection mode that makes the protection most sensitive by analyzing the sensitivity of the unbalance bridge protection.
