摘要

通过对电容器内部故障主保护失效后的故障状态

及其对后备保护的需求的研讨

分别提出:不平衡保护采取二段制配合整定配置;按电容器串联段数相应要求电容均衡程度;以及尽可能降低过电流保护定值等措施

以期充分发挥后备保护的作用。

Abstract

Through analyzing the fault states after the main internal fault protection out of work and the need for the backup protection

this paper proposes the following measures to make the backup protection working properly: two sections coordination setting for unbalance protection;limiting the balance rate of the capacitors according to the number of the capacitor bank sections;setting the over current protection to a possible lower value

etc.
