主变导电回路过热性故障的诊断

综合应用油色谱分析、红外线测温等方法对一台运行中的土变压器进行故障状态诊断，准确预测了变压器的故障部位，并对如何避免类似事故提出了建议。

Diagnosis of Overheat Fault in Conductor Circuit of Main Transformer

The fault situations of a operating main transformer are diagnosed by the methods such as the oil chromatographic analysis and the infrared temperature measurement, and the fault positions of the transformer are detected accurately. The proposals to avoid the similar faults are made.
