Rapid monitoring of dissolved gas content in transformer oil can effectively provide early warning diagnoses for potential faults. Acetylene is the most diagnostically significant fault gas. Given the inability to simultaneously perform rapid and accurate detection for all fault gases, developing a device specifically for rapid detection of acetylene holds unique value. This study constructed a rapid online chromatography monitoring system for dissolved acetylene in oil using a highly permeable Teflon-AF2400/ceramic composite membrane component for degassing, paired with a high-sensitivity NTC resistor as the sensor. Under a column temperature of 60°C, the HY-02 and HY-03 chromatography columns could fully separate acetylene from other co mponents, with retention times of 1.7 and 1.3 min, respectively. Under these conditions, the lowest detection limits for acetylene gas were 0.13 mL·L^-1 and 0.09 mL·L^-1. The permeation equilibrium curve of acetylene in the composite membrane component was measured. At room temperature, a degassing time of 25 min can achieve an oil-gas equilibrium of 82%. After correction using the Oswald coefficient, the prototype's minimum detection limit for acetylene in oil was determined to be 0.12 mL·L^-1. This device is easy to install and adjust, doesn't require many electromagnetic valves, is compact in size, and is suitable for multi-channel parallel integration. Its detection cycle is less than 30 minutes. In the event of a sudden change in acetylene concentration in the oil, it can respond with over 90% accuracy within 30 minutes.
