变压器油中溶解气体的分析及故障判断

Analysis and Fault Diagnosis of Dissolved Gas in Transformer Oil

基于火力发电厂变压器安全运行监测的油中溶解气体含量监测与分析项目,总结了特征气体法、三比值法、溶解气体注意值法、产气速率法及绝缘油理化分析法等变压器内部潜伏性故障的常用分析方法。探究分析了色谱分析诊断故障的应用案例,旨在保障变压器的安全运行。

Based on the monitoring and analysis project of dissolved gas in oil for transformer safety operation monitoring in thermal power plants,the common analysis methods of transformer internal latent faults such as characteristic gas method,three-ratio method,dissolved gas attention value method,gas production rate method and insulating oil physical and chemical analysis method are summarized.The application cases of fault diagnosis by chromatographic analysis are analyzed to ensure the safe operation of transformers.
