摘要
对2台在运10kV干式空芯电抗器绕组烧毁故障进行详细诊断分析,判断出故障原因为匝间短路使干式空芯电抗器绕组的直流电阻异常,同时提出防范措施。
The two 10 kV dry air core reactor coils burned in the operation are carried out a detailed diagnostic analysis, the cause of the failure is determined to be unnormal direct current of dry air core reactor coiles by inter-turn short circuit,and the corresponding preventive measures for improvement are proposed.
