Abstract
Power transformers are the most commonly used electrical equipment. The frequent overload operation of power transformers will cause potential safety hazards due to insulation damage. The transformer oil chromatography online monitoring system can monitor the working status of the transformer in real time through the analysis of the dissolved gas composition and content in the oil. Among them, gas chromatography analysis technology is the most widely used and Mature. This is not only beneficial to the automation of substations, reducing inspections and maintenance, but also preventing and reducing transformer failures through real-time monitoring. This paper introduces the status quo of gas chromatography-based on-line chromatographic monitoring technology for dissolved gases in transformer oil at home and abroad, compares the advantages and disadvantages of each monitoring technology, puts forward the improvement direction according to the application effect, and looks forward to the development of transformer oil chromatographic monitoring technology in the future.
