The collected data are processed, treated, analyzed, stored and published by the data storing. An application system relative to the management of the transformer operation status is constructed by the data application analysis to supply an information platform for scientific organization, commandment, decision and monitoring production process. The invention is applied to the automatic control system of the electric power supply system.

Description

technical field [0001] The invention relates to a transformer oil gas detection system for a power supply system of an electrolytic aluminum enterprise, in particular to an on-line detection method for transformer insulating oil temperature, characteristic gas in oil and oil chromatogram. Background technique [0002] As the electrolytic aluminum production process is becoming more and more detailed, the process is more complex, and there are more and more production equipment and supporting factories, the scale of the corresponding power supply system is also undergoing a series of changes, and the level of power transformers is getting higher and higher. The capacity is getting bigger and bigger, the quantity is also increasing, and the requirements for the reliability of the power system are getting higher and higher. In the past, when the number of transformers was limited and the means of analysis equipment was backward, laboratory off-line insulating oil temperature, c...

Problems solved by technology

In the past, when the number of transformers was limited and the means of analysis equipment was backward, laboratory off-line insulating oil temperature, characteristic gas in oil and oil chromatographic analysis technology were generally used. Because off-line technology uses manual collection of oil in transformers, and then adds chemical reagents in the laboratory The method of analysis involves tedious work such as separation, analysis, manual calculation, and summarization of gas in oil. The oil temperature, characteristic gas, and oil chromatographic analysis cycle are long, with low safety and poor data accuracy. Inaccurate and untimely, the transformer has harmful potential safety hazards, and even caused major safety accidents, causing loss of life and property to enterprises and people. This has seriously hindered the overall process of enterprise control level development, and has become This creates a "bottleneck" for enterprises to further improve production, making it difficult for enterprises to make decisions when making a new round of investment.

[0003] This problem of long analysis period, low safety and poor precision is common in power supply enterprises, and it is one of the problems to be solved by the online monitoring and analysis system of power transformer insulating oil temperature, characteristic gas in oil and oil chromatography
