Embodiment 1
[0037] This embodiment 1 provides a preparation method for dissolved gas in transformer oil, which is to take two parts of the same transformer oil a and b, feed gas into transformer oil a to make the gas in a reach saturation, and then make the gas in a and b The temperature is the same, combined with the Ostwald coefficient derived from Henry's law to control the flow ratio of the oil in a and b, and finally prepare the transformer oil with a specified dissolved gas concentration.
[0038] As a further refinement, the Ostwald coefficient is dependent on temperature and its formula is:
[0039]
[0040] T: actual temperature;
[0041] L 0 : Ostwald coefficient of oil at 273K;
[0042] d: density of oil at 288K;
[0043] Calculated to get L c is the Ostwald coefficient at temperature T, so the dissolved gas concentration in the final formulated oil is:
[0044]
[0045] ω g : the gas concentration (%) passed into the oil;
[0046] Q g / o : the actual flow rate of ...
Embodiment 2
[0071] The purpose of Example 2 is to prepare transformer oils with dissolved gas concentrations in No. 10 transformer oil of 350 ppm, 480 ppm and 640 ppm under the condition of 80°C.
[0072] The specific operation process of this embodiment 2 is the same as that of embodiment 1.
[0073] The final calculation shows that when the dissolved gas concentrations in the transformer oil are 350ppm, 480ppm and 640ppm respectively, the flow control ratios in the oil-gas dissolution chamber and the transformer oil control greenhouse are respectively and
Embodiment 3
[0075] The purpose of Example 3 is to prepare transformer oils with dissolved gas concentrations of 50 ppm and 200 ppm in No. 25 and No. 45 transformer oils under the condition of 80° C., respectively.
[0076] The specific operation process of this embodiment 3 is the same as that of embodiment 1.
[0077] Finally, the flow control ratios in the oil-gas dissolution chamber and transformer oil control greenhouse of No. 25 transformer oil and No. 45 transformer oil are calculated as and
