The standard oil sample configuration mode mainly includes instrument oil dispensing and manual oil dispensing. The instrument oil dispensing can only dispense 30L of standard oil sample at most once, and the oil dispensing efficiency is not high, and the mechanical structure is complex and the failure rate is high. The manual oil dispensing needs to be manually operated to mix standard gas or mother oil, and cannot be quantitatively controlled, the consistency of multiple oil dispensing is not high, and the risk of misoperation introduced by human operation is large. The standard oil sample storage is to transfer the configured standard oil sample to an empty oil storage tank, and part of the standard oil sample needs to be used for cleaning before the transfer, and the entire standard oil sample storage process needs to be manually operated, which is not suitable for automatic assembly line operation mode.

This oil dispensing method has many motor-driven elements and a complex mechanical structure.

[0004] A kind of oil dispensing device and its full-automatic oil dispensing method are disclosed in Chinese patent CN117524656A, which discloses a multi-component transformer oil standard oil configuration device and its oil dispensing method. The volume of mixed standard gas is controlled by a flow meter, and the volume of new oil is controlled by a liquid quantitative device. The oil and gas are mixed by a circulating pump. This oil dispensing method has many motor-driven elements and a complex mechanical structure.

[0005] A kind of oil dispensing device and its full-automatic oil dispensing method are disclosed in Chinese patent CN112619523B, which discloses a transformer standard oil preparation device and method. The device uses a mother oil dilution method to automatically dispense oil. First, the oil and gas are circulated by a circulating pump between a gas storage tank and an oil dispensing tank to prepare high-concentration mother oil from the oil in the oil dispensing tank. Then, a certain amount of mother oil is injected from the oil dispensing tank, and a certain amount of clean oil is injected from a clean oil tank into the oil storage tank. The oil storage tank is then left to stand for use. This method requires motor-driven elements, has a complex structure, cannot control the concentration of high-concentration mother oil, and the oil storage tank needs to be left to stand for a long time, which is not efficient.

A full-automatic control method of the oil distribution and storage integrated device according to any one of claims 1-7, characterized in that, The method comprises: S1, judging whether the flag bit state of the first oil storage tank and / or the second oil storage tank is 1, if yes, executing the oil discharging process, if no, executing step S2; S2, acquiring the liquid level in the second oil distribution tank, judging whether it is in the oil distribution state, if yes, executing step S3, if no, executing the oil distribution process; S3, judging whether the flag bit of the first oil storage tank is 0, if yes, controlling the eighth two-way valve and the third three-way valve 203 to open, and controlling the oil distributed in the second oil distribution tank to be injected into the first oil storage tank, if no, executing step S4; S4, judging whether the flag bit of the second oil storage tank is 0, if yes, controlling the seventh two-way valve and the third three-way valve to open, and controlling the oil distributed in the second oil distribution tank to be injected into the second oil storage tank, if no, waiting for the oil discharging process.

9. The fully automatic control method according to claim 8, characterized in that, In S1, specifically comprising: judging whether the flag bit state of the first oil storage tank is 1, if yes, controlling the fourth three-way valve and the ninth two-way valve to open, and executing the oil discharging process, if no, executing step S2, and judging whether the flag bit state of the second oil storage tank is 1, if yes, controlling the fifth three-way valve and the tenth two-way valve to open, and executing the oil discharging process, if no, executing step S2.

10. The fully automatic control method according to claim 8, characterized in that, In S2, the oil distribution process comprises: S21, judging whether the second oil distribution tank is in the oil distribution state, if yes, executing step S3, if no, executing step S22; S22, controlling the oil distribution part to be initialized; S23, controlling the oil distribution part to be connected with the clean oil injection port, and cleaning the first oil distribution tank, the second oil distribution tank and the quantitative gas filling tank by clean oil; S24, after the clean oil cleaning is completed, controlling the oil distribution part to be connected with the high-purity air injection port, and cleaning the quantitative gas filling tank by high-purity air; S25, after the high-purity air cleaning is completed, the control oil is injected into the first oil tank, the mixed standard gas is injected into the quantitative gas tank, and the mixed standard gas is mixed with the clean oil in the first oil tank; S26, the oil gas mixture in the first oil tank is controlled to pass through the set number of times of tank inversion, and the oil gas mixture is controlled to be inverted between the first oil tank and the second oil tank; S27, after reaching the set number of times of tank inversion, the exhaust is performed, and the oil after the exhaust is stored in the second oil tank, and the oil distribution is completed.
