| 摘 要： | 利用动态预浓缩方法对溶解在变压器油中的乙炔、乙烯和乙烷进行了富集，在１０ｍＬ顶空气体的进样量下得到了１００倍的富集效果，因此可以用热导检测器替代氢火焰离子化检测器，使在线检测成为可能，通过比较溶解气体从变压器油中脱出的方法发现，超声振荡比机械振荡的脱气效率提高几十至上百倍。

| Abstract: | C 2 hydrocarbons dissolved in transformer oil was enriched hundred times. An enrichment factor by using a dynamic preconcentration system obtained with 10 mL of gas sample. The preconcentration system could use TCD instead of FID for on line monitoring of fault gases dissolved in transformer oils. It was found that degassing efficiency of ultrasonic vibration is much better than that of mechanical vibration. |
