Embodiment 1
[0024] Preparation of Very Low Standard Oil Samples:
[0025] First, determine the target concentration oil sample, and calculate the required oil volume and standard gas content according to the target concentration through the oil sample preparation formula.
[0026] 1
[0027] Degassing is carried out by vacuum degassing, and the obtained blank transformer oil concentration is:
[0028] 1
[0029] The prepared blank oil sample is injected into a variable-volume sealed container with a rubber gas injection pad through a closed pipeline.
[0030] Inject the calculated standard gas into the airtight container containing the blank oil sample.
[0031] Put the above-mentioned airtight container containing the blank oil sample and standard gas into a high-temperature box at 50°C, and turn on the power circulation pump for 24 hours. Oil test:
[0032] 1
[0033] According to the error statistics, it can be seen that the standard oil sample configur...
