35kV线路短路故障继电保护动作行为分析

Analysis on Relay Protection Action of 35kV Line Short Circuit Fault

介绍35kV线路短路故障发生经过及继电保护动作情况,通过保护Ⅰ、Ⅱ动作报告分析和理论公式推导,证明主变压器保护动作正确,并针对故障发生的原因提出防范措施。

This paper introduces 35 kV line short circuit fault courses and relay protection action circus,through analysis on protection I and II action report,and theory formula derivation,testifies the protection action of main transformer is correct,and advances the countermeasures for the causes of the fault.
