[0002] With the rapid development of intelligent online monitoring substations both domestically and internationally, online monitoring devices for dissolved gas in transformer oil have become widely used in smart substations. These devices enable real-time monitoring of dissolved gas in the insulating oil within transformer bushings, reducing the workload for substation operators and allowing real-time remote viewing of gas composition data in the oil from the control room. To ensure smooth operation and maintenance, online monitoring devices for dissolved gas in oil must be tested for accuracy and functionality.

[0003] Oil sample preparation is an essential step in the testing of online monitoring systems for dissolved gases in transformer oil. With the development of standard oil sample preparation machines, traditional manual oil sample preparation has gradually been replaced. However, these machines often lack corresponding standard oil storage devices and waste oil recycling systems. The prepared standard oil sample can only be used once for online monitoring device testing. After testing, the oil sample is discarded and cannot be recycled, resulting in a certain degree of resource waste.

[0004] Therefore, we propose an oil sample self-circulating device for a standard oil sample configuration machine in order to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0021] An oil sample self-circulating device for a standard oil sample preparation machine includes an oil tank 1. It should be noted that a partition 14 is vertically fixed inside the oil tank 1, and the partition 14 divides the interior of the oil tank 1 into a waste oil holding chamber 2 and a standard oil holding chamber 3; through the arrangement of the waste oil holding chamber 2 and the standard oil holding chamber 3, waste oil and treated oil can be stored.

[0022] The lower portion of the oil tank 1 is provided with a liquid inlet 4 connected to the waste oil holding chamber 2. Through the provision of the liquid inlet 4, the waste oil after the experiment can be transported into the waste oil holding chamber 2. A pipe 12 is provided on the liquid inlet 4, and a first solenoid valve 13 is provided on the pipe 12. The provision of the first solenoid valve 13 closes the liquid inlet 4 to prevent the waste oil in the waste oil holding chamber 2 from flowing back.

[0023] The lower part of the oil tank 1 is equipped with a liquid outlet 5 which is connected to the standard oil holding chamber 3. Through the setting of the liquid outlet 5, the treated oil can be discharged from the liquid outlet 5. A pipe 12 is also installed on the liquid outlet 5, and a first solenoid valve 13 is also installed on the pipe 12. Through the setting of the first solenoid valve 13, the liquid outlet 5 is closed, so that the oil can be stored in the standard oil holding chamber 3.

[0024] A liquid extraction pipe 6 is installed inside the waste oil holding chamber 2, and the bottom end of the liquid extraction pipe 6 is located at the lower part of the waste oil holding chamber 2, so as to ensure that the waste oil in the lower part of the waste oil holding chamber 2 is extracted; a liquid extraction pump 7 extending to the outside of the oil tank 1 is installed at the top of the liquid extraction pipe 6. It should be noted that the liquid extraction pump 7 is a metering pump. By setting the liquid extraction pump 7, the waste oil in the liquid extraction pipe 6 can be extracted. A delivery pipe 8 is installed at the output end of the liquid extraction pump 7, and a vacuum box 9 is installed on the delivery pipe 8. The vacuum box 9 is connected to the vacuum pump through a vacuum pipe 10. 11 is connected, and the extracted waste oil can be transported to the vacuum box 9, and the hydrogen, carbon dioxide, methane and acetylene in the waste oil can be extracted by the vacuum pump 11. A one-way valve 17 is also installed on the delivery pipe 8, and the one-way valve 17 is located between the vacuum box 9 and the filter element 16; when the one-way valve 17 is opened, the oil after vacuum extraction can enter the filter element 16 for subsequent treatment, and the output end of the delivery pipe 8 extends to the standard oil holding chamber 3; so that the treated oil can be transported to the interior of the standard oil holding chamber 3 and stored;

[0025] A second solenoid valve 15 is installed on the liquid extraction pipe 6, and the second solenoid valve 15 is located outside the oil tank 1. The second solenoid valve 15 is set to close the liquid extraction pipe 6 to prevent the oil in the liquid extraction pipe 6 from flowing back.

[0026] A second solenoid valve 15 is also installed on the delivery pipe 8, and the two second solenoid valves 15 are also located outside the oil tank 1. The setting of the second solenoid valve 15 plays a role in closing the delivery pipe 8. When the device is not in use, it prevents the oil in the delivery pipe 8 from flowing into the interior of the standard oil holding chamber 3.

[0027] A filter element 16 for filtering the oil is installed on the delivery pipe 8, and the filter element 16 is located between the vacuum box 9 and the second solenoid valve 15. Through the setting of the filter element 16, impurities in the oil can be filtered and the oil can be further processed.

[0028] How it works

[0029] After the experiment, the waste oil enters the waste oil holding chamber 2 through the pipeline 12 and the liquid inlet 4 in turn, and then the liquid extraction pump 7 and the vacuum pump 11 are turned on. The liquid extraction pump 7 can extract the waste oil in the waste oil holding chamber 2 through the liquid extraction pipe 6, and the extracted waste oil can enter the interior of the vacuum box 9. The hydrogen, carbon dioxide, methane, acetylene and other gases in the waste oil are extracted through the vacuum pump 11, and then the one-way valve 17 is opened. The vacuumized oil can enter the interior of the filter element 16, and the impurities in the oil can be filtered through the filter element 16. The filtered oil flows into the interior of the standard oil holding chamber 3 through the delivery pipe 8, thereby completing the treatment work. The treated oil can be used for the next experiment.
