Application of Gas Chromatography in Malfunction Diagnosing System of Transformer

摘要

The malfunction diagnosing system of transformer based on gas chromatography is designed for detecting the gas component, content and speed of gas producing in the oil of transformer, finding out the potential malfunction in the transformer as soon as possible and judging whether it will endanger the running of the transformer. The system applies the analysis method of gas chromatography to transform each of the concentration into analog signal pro direct ratio to concentration. After AD conversion, the signal is transmitted into computer to form chromatogram and made a malfunction diagnosing. The system can detect the internal running state of transformer by the measure and analysis of dissolved gases in oil. It ensures safe and economical running of the transformer.
