摘要

根据干式变压器接地短路故障现场勘查情况、故障波形特征、试验结果及其他相关资料,分析干式变压器A相连杆对进线电缆屏蔽层放电引发接地短路的故障原因.针对故障原因,从干式变压器设计、制造、运维等方面给出了改进建议.

Abstract

According to relevant archives,such as on-site investigation,fault waveform characteristics,test results,of ground short circuit faults of dry-type transformers,the present work performed an analysis on the fault mechanism of A-phase connecting rod's discharge to shield layer of incoming cable.It also proposed some improvement suggestions against fault occurrence from the aspects of design,manufacturing,operation and maintenance of dry-type transformers.
