Description

Technical Field

[0001] The present application relates to the technical field of metering devices, and more specifically, to a transformer oil control metering device. Background Art

[0027] The present application embodiment discloses a transformer oil control metering device. Figure 1 , Figure 2 and Figure 3 , including an oil tank 1 and an oil tank 2, the outer sides of the oil tank 1 and the oil tank 2 are provided with auxiliary mechanisms, and the auxiliary mechanisms extend to the inside of the oil tank 1 and the oil tank 2;

[0028] The auxiliary mechanism includes a threaded collar 1 3 and a threaded collar 2 4, which are fixedly connected to the oil tank 1 1 and the oil tank 2 2 respectively, a seamless steel pipe 1 5 is inserted into the internal thread of the threaded collar 1 3, a seamless steel pipe 2 6 is inserted into the internal thread of the threaded collar 2 4, and the seamless steel pipe 1 5 and the seamless steel pipe 2 6 are installed and connected via a threaded collar 3 7, a threaded collar 4 8 is fixedly connected to one side of the oil tank 2 2, an oil inlet pipe 9 is inserted into the internal thread of the threaded collar 4 8, a flow meter 10, an oil filter meter 11 and a degasser 12 are arranged on one side of the oil tank 2 2, the flow meter 10 and the degasser 12 are respectively located at the top and bottom of the oil filter meter 11, and the flow meter 10, the oil filter meter 11 and the degasser 12 are all connected to the oil tank 2 2 via the oil inlet pipe 9;

[0029] See also Figure 1 and Figure 3 , a connecting component is provided on the outside of the oil inlet pipe 9, and the connecting component includes a connecting pipe 13, and the connecting pipe 13 is installed and connected to one side of the degasser 12. An electric valve 14 is sleeved on the outside of the connecting pipe 13. The inner walls of the threaded collar 13, the threaded collar 24, the threaded collar 37 and the threaded collar 48 are all made of anti-slip material. Because the inner walls of the threaded collar 13, the threaded collar 24, the threaded collar 37 and the threaded collar 48 are all made of anti-slip material, the association between the seamless steel pipe 15, the seamless steel pipe 26 and the oil inlet pipe 9 and the oil tank 11 and the oil tank 22 can be strengthened, and the loosening problem can be avoided at the same time;

[0030] See also Figure 1 and Figure 2 , a magnetic induction switch 15 and a magnetic induction switch 2 16 are embedded inside the oil tank 1 and the oil tank 2, respectively. The top and bottom of the oil tank 1 and the oil tank 2 are both set in arc shape. The other side of the oil tank 1 is provided with an electric valve 2 17, a gear pump 18 and an electric contact pressure protector 19. The electric valve 2 17 and the electric contact pressure protector 19 are respectively located on both sides of the gear pump 18. Since the top and bottom of the oil tank 1 and the oil tank 2 are both set in arc shape, the impact force generated during the collision can be reduced. At the same time, since the electric contact pressure protector 19 is provided, the drive control device will automatically shut down when the pipeline pressure exceeds the range, thereby achieving the purpose of protecting the sealing of the pipeline;

[0031] See also Figure 1 and Figure 2 The electric valve 17, the gear pump 18 and the electric contact pressure protector 19 are all connected to the oil tank 2 through the seamless steel pipe 6.

The oil tank 1 and the oil tank 2 are both made of steel, and the inner walls of the oil tank 1 and the oil tank 2 are coated with an anti-corrosion coating.

[0032] The implementation principle of this embodiment is as follows: during use, the oil tank 1 of the oil filter room is connected to the oil tank 2 of the central oil depot through the seamless steel pipe 15 and the seamless steel pipe 26, and an electric valve is installed at the outlet of the oil tank 2 of the central oil depot. Because the inlet of the oil tank 2 of the central oil depot is connected to the flow meter 10, the oil filter meter 11 and the degasser 12 through the oil inlet pipe 9, the flow meter 10 can achieve the purpose of accurately recording the weight of the crude oil. At the same time, because the electric contact pressure protector 19 is installed, the drive control device will automatically shut down when the pipeline pressure exceeds the range to protect the pipeline sealing. In addition, because the distance between the oil tank 2 and the oil tank 2 is A magnetic induction switch 16 is installed five centimeters from the oil outlet. Therefore, when the stored oil is low to this position, the gear pump 18 in operation will automatically stop to prevent the transformer oil in the oil tank from being pumped out. Similarly, since a magnetic induction switch 15 is installed five centimeters from the top of the oil tank 1, when the pumped crude oil reaches this position, the gear pump 18 in operation will also automatically stop to prevent the oil in the oil tank from being full. Through the above structure, the problem of mixing crude oil with refined oil, which will cause different oil grades to be in a mixed state, and when the weight of the crude oil needs to be measured, another set of measuring equipment must be designed for measurement, which increases the cost.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
