一起110 kV电流互感器跳闸事故原因分析

Cause Analysis of A 110 kV Current Transformer Tripping Accident

摘要:

文中结合一起110 kV电流互感器一次放电导致变压器及母线跳闸事故展开分析，通过对事故互感器的检查、试验，结合现场检查情况和故障录波对事故动作逻辑进行反复推演分析，判断出事故原因，还原事故经过，并提出合理的整改建议。

Abstract:

A transformer and bus tripping accident caused by a single discharge of 110 kV current transformer is analyzed. Through the inspection and test of the faulty transformer, and combined with the on-site inspection and fault recording, the accident action logic is repeatedly deduced and analyzed, the cause of the accident is judged, the accident process is restored, and the reasonable improvement suggestions are put forward.
