电力机车变压器油溶解气体分析及故障判断的研究

Analysis of dissolved gas in electric locomotive transformer oil and study of fault diagnosis

根据现场检测电力机车牵引变压器油中溶解气体含量的实际情况,通过对机车牵引变压器故障的机理、变压器油的气相色谱分析、三比值法、产气速率等进行研究,来判断机车牵引变压器内部潜伏性故障及故障的性质,为检修技术部门提供排除故障的科学依据。

According to the actual situation inspected on-site of dissolved gas content in electric locomotive traction transformer oil and the study of fault mechanism of locomotive traction transformer,gas chromatography analysis of transformer oil,three ratio method and gas production rate,internal latent failure and the nature of the fault are diagnosed to provide the scientific basis for maintenance technical department.
