摘要
不平衡保护动作是电容器组故障的主要保护,介绍了电容量不平衡保护的方式,分析了不平衡电压的产生原因,总结了不平衡保护的动作原因并实际举例说明,得出了安装质量与实际故障设备对电容器不平衡保护的影响,为电力检修工作人员处理电容器组故障提供了思路。
Tripping operation of the unbalanced protection is the mostly protection in the breakdown of the capacitor bank. This paper introduces the way of the unbalanced protection and analyzes the production reason of the unbalanced voltage. It sums up the reason of the unbalanced protection and gives examples by way of the fault of the capacitor bank. It reaches the conclusion that the installment quality and the breakdown equipment has influence on the unbalanced protection.This paper offers the methods for the engineers of the examining and repairing of the capacitor bank.
