一例过流保护跳闸的故障分析和试验

An over-current protection tripping fault analysis and test

文章中故障分析主要集中在故障点的判断、变压器运行参数整定及一起比较罕见的过电压保护器故障,还有后面对于过电压保护器故障的进一步试验证实,旨在对电气维修经验的总结和交流提供帮助。

This article focuses on the judgment of fault point,fault analysis of transformer running parameters setting and the fault of the relatively rare over-voltage protector, and then to further test the over-voltage protector failure confirmed that aims to provide help for the summary of experience on electrical maintenance and communication.
