一起主变油中总烃超标的故障分析

Diagnose Analysis on Abnormal Chromatographic Data of Transformer

介绍对变压器油样使用气相色谱法获得油中溶解的特征气体浓度后,对其进行分析就可以对变压器的内部潜伏性故障的性质和严重程度进行判断,实践证明,用气相色谱法能有效地发现充油电力设备内部的潜伏性故障及其发展程度。通过对一台220kV主变总烃超标的分析,为同类型设备故障提供了分析思路。

Take transformer sample using gas chromatography method for the characteristics of the gases dissolved in transformer oil concentration, can analyze the transformer fault case. Based on a 220 kV main transformer total hydrocarbon exceeds bid analysis, provides the same type equipment failure analysis.
