Description

Technical Field

[0001] This utility model relates to a transformer oil and gas separation device, and more particularly to a transformer oil and gas separation device for online oil chromatography monitoring. Background Technology

[0002] Online oil chromatography monitoring detects and diagnoses internal transformer faults by analyzing the content and trends of fault gases in transformer oil. It provides crucial data for real-time monitoring of transformer operating status and is a vital device for ensuring the safe and economical operation of transformers and power grid systems. Therefore, transformer oil and gas separation devices used for online oil chromatography monitoring are important transformer monitoring components. Currently, most transformer oil and gas separation devices for online oil chromatography monitoring utilize headspace degassing. In this method, the gas components above the liquid or solid sample reach equilibrium with the sample's own components within a sealed container. During headspace degassing, the sample is placed in a sealed container, which is then heated to a certain temperature or stirred to evaporate volatile components into the gas above the container. The gas above the container is then extracted using a vacuum pump and injected into a gas chromatograph or other analytical instrument for analysis. Because headspace degassing is an analytical technique based on headspace equilibrium, this method can affect the effectiveness of removing fault gases from transformer oil.

[0003] This invention provides an effective technical exploration and research into the technical problem of headspace degassing by using the technical feature of removing fault gas by subjecting transformer oil to forced vacuum and oscillating reflux. Summary of the Invention

The center line of the washing seat 1, the center line of the lower telescopic cylinder 8, and the center line of the upper telescopic cylinder 9 are arranged on the same straight line. The shell part II 99 and the shell part I 81 are respectively connected to the seat part 11.

[0077] The usage method of this embodiment is as follows: When the motor unit I83 is in the working state, the power screw unit I82 rotates in the convex hole of the piston head I80 and the central threaded hole of the motor unit I83, driving the piston head I80 to move upward in the shell part I81, so that the piston head I80 is in the upper position. The magnetic ring unit I84 generates a trigger signal to the inductive switch I85, and the inductive switch I85 inputs a signal to the PLC controller, so that the motor unit I83 is in the non-working state. When the motor unit I83 is in the working state, the power screw unit I82 rotates in the opposite direction in the convex hole of the piston head I80 and the central threaded hole of the motor unit I83, driving the piston head I80 to move downward in the shell part I81, so that the piston head I80 is in the lower position. The magnetic ring unit I84 generates a trigger signal to the inductive switch II86, and the inductive switch II86 inputs a signal to the PLC controller, so that the motor unit I83 is in the non-working state.

[0078] When motor unit II97 is in the working state, the power screw unit II98 rotates in the U-shaped hole of piston head II90 and the central threaded hole of motor unit II97, driving piston head II90 to move downward in cylinder shell II99, placing piston head II90 in the lower position. Magnetic ring unit II96 generates a trigger signal to inductive switch III95, which in turn inputs a signal to the PLC controller, deactivating motor unit II97. When motor unit II97 is in the working state, the power screw unit II98 rotates in the opposite direction in the U-shaped hole of piston head II90 and the central threaded hole of motor unit II97, driving piston head II90 to move upward in cylinder shell II99, placing piston head II90 in the upper position. Magnetic ring unit II96 generates a trigger signal to inductive switch IV94, which in turn inputs a signal to the PLC controller, deactivating motor unit II97.

[0079] The PLC controller is activated, piston head I80 is in the upper position, and piston head II90 is in the lower position. One port of the first valve 2 is connected to the transformer oil storage tank, making the first valve 2 open and the second valve 3 and third valve 4 closed. This causes piston head I80 to change from the upper position to the lower position, allowing transformer oil from the storage tank to enter the shell section I81. The third valve 4 and fourth valve 7 are then opened, and the first valve 2 and second valve 3 are closed. This causes piston head I80 to change from the lower position to the upper position, allowing transformer oil to enter the tank section 61. Air in the tank section 61 is discharged through the fourth valve 7. When the fourth valve 7 begins discharging transformer oil, it is closed. The level sensor 62 picks up the transformer oil level signal from the tank section 61. Another port of the fourth valve 7 is connected to the transformer oil storage tank, thus completing the venting of the washing seat 1 and the collection tank 6.

[0080] The first valve 2 is opened, and the second valve 3 and the third valve 4 are closed. This causes the piston head I80 to change from the upper position to the lower position, allowing transformer oil from the transformer oil storage tank to enter the shell section I81, thus achieving transformer oil sampling. After sampling is complete, the first valve 2 is closed.

[0081] When piston head II90 is in the lower position, it moves from the lower position to the upper position, creating a vacuum in the shell section II99. Transformer oil in shell section I81 enters shell section II99 through channel III14. When piston head II90 is in the upper position, under gravity, the transformer oil in shell section II99 flows back to shell section I81 through channel III14, separating fault gases from the transformer oil. When the transformer oil is in shell section I81 and piston head II90 is in the upper position, the second valve 3 is open. This causes the piston head II90 to move from the upper position to the lower position, transporting the faulty gas to the gas collecting box 5. With piston head II90 in the lower position, the second valve 3 is closed, thus completing one faulty gas separation process. Repeating this process multiple times allows for sampling of the faulty gas. This opens the shut-off valve at the output port of the gas collecting box 5, injecting the sampled faulty gas into the online oil chromatograph. Once the sampled faulty gas is injected into the online oil chromatograph, the shut-off valve at the output port of the gas collecting box 5 is closed.

[0082] The third valve 4 and the fourth valve 7 are opened, causing the piston head I80 to move from the lower position to the upper position. When the piston head I80 is in the upper position, the transformer oil flows back to the transformer oil storage tank through the tank 61. After the transformer oil has flowed back to the transformer oil storage tank, the fourth valve 7 is closed, and the second valve 3 is opened. The fault gas in the tank 61 is injected into the gas collecting box 5 through the third valve 4 and the second valve 3. After the fault gas in the tank 61 has been injected into the gas collecting box 5, the second valve 3 and the third valve 4 are closed.

[0083] In verifying this utility model, the inventors abandoned the existing technical features of headspace degassing and first proposed a technical feature of removing fault gas by subjecting the transformer oil to forced vacuum and oscillating reflux. This resulted in the first unexpected technical effect: the fault gas was extracted under external interference with the transformer oil, improving the efficiency of removing fault gas from the transformer oil. The second unexpected technical effect: the external interference effect generated by the screw-driven cylinder was achieved, optimizing the structure of the transformer oil and gas separation device and improving the docking effect with the transformer oil storage tank. The third unexpected technical effect: the use of the washing seat 1 as an intermediate support improved the aggregation performance of the extracted fault gas. The fourth unexpected technical effect: the vertical interference effect generated by the lower telescopic cylinder 8 and the upper telescopic cylinder 9 on the transformer oil improved the oscillation performance of the transformer oil. The fifth unexpected technical effect: the return of the transformer oil to the transformer oil storage tank by the third valve 4, the collection tank 6, and the fourth valve 7 prevented gas from entering the transformer oil storage tank and improved the performance of the transformer.

[0084] In the second embodiment of this utility model, the transformer oil and gas separation device body, the lower telescopic cylinder 8 and the upper telescopic cylinder 9 are interconnected in a manner that the fault gas is removed by making the transformer oil under a forced vacuum and oscillating reflux state.

[0085] In this embodiment, the lower telescopic cylinder 8 and the upper telescopic cylinder 9 are connected to the main body of the transformer oil and gas separation device in a manner that allows for the pumping of transformer oil.

[0086] In this embodiment, the transformer oil and gas separation device body is configured to also include a first valve 2, a second valve 3, and a gas collection box 5.

[0087] In this embodiment, a first accessory device is also included and is disposed on the body of the transformer oil and gas separator. The first accessory device is configured to include a third valve 4, a liquid collection tank 6 and a fourth valve 7.

The transformer oil is pumped through the lower telescopic cylinder 8 and the upper telescopic cylinder 9. The fault gas is removed by putting the transformer oil under forced vacuum and oscillating reflux. This solves the technical problem of using headspace degassing, thus improving the effect of removing fault gas from transformer oil.

[0090] 2. Due to the design of the washing seat 1, the first valve 2, the second valve 3 and the gas collection box 5, the fault gas can be collected.

[0091] 3. Due to the design of the third valve 4, the liquid collection tank 6 and the fourth valve 7, the connection with the transformer oil storage tank is realized.

[0092] 4. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this utility model, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0093] 5. Due to the design of the technical features of this utility model, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this utility model are at least 1.7 times that of existing performance indicators, and it has been evaluated that it has great market value.

Furthermore, the technical features of the above embodiments can be combined in any way.
