When the fifth liquid level sensor 5 no longer outputs a signal, the oil pump 8 is in non-working condition, and the second valve 13, the eighth valve 6 and the sixth valve 9 are closed.

[0079] When verifying the utility model, the inventor abandoned the existing technical feature of directly injecting standard gas with the concentration of the detected gas component into the transformer crude oil in a sealed state and controlling the injection amount of the standard gas through a flow meter to allow the transformer crude oil and the standard gas to be freely dissolved. Firstly, a technical feature of controlling the injection amount of the standard gas, which is the second raw material of the standard oil sample, by the evolution process of the vacuum state was proposed, and the first unexpected technical effect was obtained: the control of the dissolved amount of the standard gas by the state signal was achieved, and the second unexpected technical effect was obtained: the purity treatment of the transformer crude oil was achieved, and the content of other gases was reduced, and the third unexpected technical effect was achieved: the dissolved amount of the transformer crude oil and the standard gas was prepared under negative pressure and the dissolved amount of the transformer crude oil and the standard gas was prepared under positive pressure. The transformer crude oil and the standard gas are dissolved, and the fourth unexpected technical effect is obtained: the standard oil sample is prepared on-site at the transformer use site, which meets the diverse needs of the transformer use environment. The fifth unexpected technical effect is obtained: the vacuum state with a pressure value less than -98kpa has the best accuracy for the dissolution of carbon monoxide, methane, carbon dioxide and nitrogen in the standard gas in the transformer crude oil, ensuring the consistency of the performance parameters of the standard oil sample. The sixth unexpected technical effect is obtained: the working state of the standard oil sample preparation device corresponding to the pressure value of -98kpa is a standard atmospheric pressure. When the air pressure of the standard oil sample preparation device in the working state changes, the pressure value in the dissolving tank 16 needs to be adjusted by a ratio of -98kpa to correspond to the air pressure change at the transformer use site.
