摘要
本文中作者对一起特高压柔直换流变压器网侧屏蔽管放电及其引起储油柜油位异常的现象和原因进行了分析,通过解体检查和电场分布仿真分析,找出了故障原因。
The the phenomenon and causes of abnormal oil level in the oil conservator caused by the discharge of the shielding tube at the grid side in the process of quality control of UHV flexible direct converter is analyzed by the authors in this paper.Based on disassembly inspection and electric field distribution simulation analysis,the cause of the fault is found.
