摘要
本文结合两起330kV变电站35kV系统的单相接地故障处理过程,叙述了该类型故障发生时伴随的一些典型现象。然后通过原理图和故障分析,阐明了故障现象出现的原因,并针对性的提出了一套简单可靠的故障查找流程及后续处理方法,可供运维人员参考。
Some typical phenomena have been depicted in this paper along with the occurrence of fault in the process of single-phase grounding in 35kV system in two substations of 330kV as example. Then, through the analysis of the principle diagram and fault, the cause of the fault phenomenon has been expounded, and a set of fault finding process and the subsequent processing method that is simple and reliable has been put forward, which can be a reference for the operation and maintenance personnel.
