| Abstract: | A new gas chromatograph column and a transformation oven for analysis of transformer oil are described in the present paper. The transformation oven is made using a metallic capillary with the length of 3cm. The analysis of seven compounds, including H2, CO, CH4, CO2, C2H4, C2H6 and C2H2, in the transformer oil be completed with only one column and by only one injection using this method. Figure 1 is the GC chromatogram of seven compounds in the transformer oil. Table 1 shows the transformation rates of CO and CO2 in different transformation temperatures and column temperatures, respectively. The transformation oven designed has high transformation rate, long life and thus can reduce the cost of the instrument. |
