Description

Technical Field

[0001] The present invention relates to the technical field of transformer oil storage, and particularly to a long-term storage method for transformer oil. Background Art

[0002] Transformer oil is a fractionation product of petroleum. Its main components are alkanes, cycloalkane saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds. It is commonly known as square shed oil, a light yellow transparent liquid. Transformer oil is a mineral oil obtained by distillation and refining from natural petroleum. It is a mixture of liquid natural hydrocarbons with pure, stable, low viscosity, good insulation and good cooling properties obtained by acid-base refining of the lubricating oil fraction in petroleum. Transformer oil has a much higher insulation strength than air. When insulating materials are immersed in the oil, not only can the insulation strength be improved, but also they can be protected from moisture erosion. Therefore, to ensure the safe power supply in modern times, a large amount of transformer oil is manufactured and stored to meet the manufacturing requirements of transformers;

[0003] However, the existing transformer oil will be in continuous contact with air during manufacturing and transportation, so that some moist air will be mixed with the transformer oil, resulting in accelerated oxidation of the transformer oil during long-term storage, thus reducing the insulation performance of the transformer oil and causing danger when the transformer oil is used. To avoid the above technical problems, it is indeed necessary to provide a long-term storage method for transformer oil to overcome the defects in the prior art. Summary of the Invention

[0004] The present invention provides a long-term storage method for transformer oil, which can effectively solve the problem that the existing transformer oil is in continuous contact with air during manufacturing and transportation, so that some moist air is mixed with the transformer oil, resulting in accelerated oxidation of the transformer oil during long-term storage, thus reducing the insulation performance of the transformer oil and causing danger when the transformer oil is used as mentioned in the above background art.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use:

[0027] 1. A purification component is provided. The acetone solution is sprayed towards the position of the circulation pipe, so as to prevent the acetylene gas from mixing with the transformer oil, prevent the acetylene from mixing in the transformer oil, and prevent the test results from being affected when testing the working state of the transformer oil in subsequent use. The separation barrel is driven to rotate inside the fixed frame through the driven groove and the support rod, so as to preliminarily separate the water from the transformer oil, prevent the water from accelerating the oxidation of the transformer oil, thereby ensuring the insulation of the transformer oil. Then, through the filtration of the filter silicon molecular sponge, the impurities can be further separated from the transformer oil, further improving the purity of the transformer oil, and further improving the insulation of the transformer oil, and improving the service performance of the transformer;

[0028] Among them, in the separation, the idea of one-stage multi-movement is realized, the oil, impurities and water are separated, and then processed again. On the contrary, only the water and impurities will be reprocessed, while the transformer oil will be almost perfectly recovered. During the work, the safety effect is high, and during the overall operation, it will not be affected by the outside world, and one or two sponges can be selected for installation according to requirements, realizing different separation technologies for different oil products. At the same time, during the overall operation, the transformer oil can be continuously added, and in such an operation, the automation improvement is realized.

[0029] 2. An inflation component is provided, and the transformer oil is pumped out through a flow-limiting jet head and a manifold pipe. At this time, a large amount of transformer oil will be transported to the position of the suction pipe. When the operator observes the transformer oil from the position of the observation glass, the valve outside the suction pipe is closed, and then the nitrogen pump and the nitrogen valve are opened, so that nitrogen can be transported from the nitrogen pipe to the position of the manifold pipe, and then the pumped transformer oil and nitrogen are transported to the inside of the storage tank through the manifold pipe and the flow-limiting jet head, so as to fill the inside of the storage tank with nitrogen, further ensuring the stability of the transformer oil inside the storage tank, further delaying the oxidation reaction of the transformer oil, prolonging the storage time of the transformer oil, and ensuring that the transformer oil can be stored for a long time.

[0030] 3. An oil outlet component is provided. When people need to use the transformer oil, they can pull the connecting base to overcome the magnetic force limitation of the positioning magnet, and then slide the weight-adjusting seat outside the sliding groove, so that the storage tank can offset to one side inside the connecting base through the positioning rod and the positioning bearing, and then the internal transformer oil will tend to the side of the flow pipe, and then people can conveniently and quickly pump out the internal transformer oil, improving the use efficiency of the transformer oil.

[0031] In summary, through the centrifugal separation of the separation barrel, the impurities and mixed water generated in the manufacturing and transportation processes can be initially separated to ensure the dryness and cleanliness of the transformer oil side, providing a preliminary environment and conditions for long-term storage. Then, the air inside the storage tank is quickly discharged through the air outlet pipe and the manifold pipe, further reducing the oxidation environment inside the storage tank. Finally, a large amount of inert nitrogen is filled into the inside of the storage tank to further delay the oxidation reaction of the transformer oil, maximizing the storage time of the transformer oil, ensuring the various performances of the transformer oil, and further improving the use stability and safety of the transformer. It can store the transformer oil effectively and reasonably, prevent electrostatic interference, manage the transportation and inflow, ensure the quality, achieve more secure and effective protection, and is suitable for better promotion and use.

[0064] The working principle and usage process of the present invention: First, before storing oil, the transformer oil is first introduced to the top position of the separation barrel 208. At this time, this oil will flow to the inner position of the high molecular silicon oil-absorbing sponge 211. At the same time, the active servo motor 215 is turned on to drive the rotation of the active disk 216, thereby driving the separation barrel 208 to rotate inside the fixed frame 212 through the driven groove 213 and the support rod 207 to generate a large amount of centrifugal force. At this time, the water with a higher density and the transformer oil containing impurities will be thrown out from the spitting groove 210. Then, as the transformer oil is continuously filled, the oil separated by centrifugation will flow to the inner position of the oil collection funnel 227 through the oil separation groove 209. And at this time, due to the non-water-absorbing property of the high molecular silicon oil-absorbing sponge 211 during centrifugation, the water will penetrate through the gaps of the high molecular silicon oil-absorbing sponge 211 and be thrown to the position of the outer filter silicon molecular sponge 218. At this time, this water will flow along the inner wall of the filter silicon molecular sponge 218 to the inner position of the water collection box 222. After the transformer oil containing impurities is thrown out from the spitting groove 210 during separation, it will come into contact with the filter silicon molecular sponge 218, and the transformer oil containing impurities will be absorbed by the filter silicon molecular sponge 218;

[0065] Then the impurities will be absorbed by the filter silicon molecular sponge 218. After separation for a period of time, the compression hydraulic tappet 220 is controlled to retract, thereby driving the connecting rod 221 to retract to press the pressing ring 219 downward. Subsequently, the filtered transformer oil inside the filter silicon molecular sponge 218 is extruded, so that the transformer oil is extruded through the oil outlet hole 203 to the inner position of the oil collection funnel 227, and then is extruded through the oil inlet pipe 223 to the inner position of the fuel storage tank 301;

[0066] At this time, the oil outlet pump 225 is opened to transport the acetone solution inside the acetone solution box 224 to the liquid separation pipe 226, and then the acetone solution can be sprayed towards the position of the circulation pipe 302, so as to prevent the acetylene gas from mixing with the transformer oil, prevent the transformer oil from being mixed with acetylene, and prevent the test results from being affected when people test the working state of the transformer oil during subsequent use. The separation barrel 208 is driven to rotate inside the fixed frame 212 through the driven groove 213 and the support rod 207, so as to preliminarily separate the water from the transformer oil, prevent the water from accelerating the oxidation of the transformer oil, and thus ensure the insulation of the transformer oil. Then, through the filtration of the filter silicon molecular sponge 218, the impurities can be further separated from the transformer oil, further improving the purity of the transformer oil, and further enhancing the insulation of the transformer oil and the service performance of the transformer;

[0067] Next, the filtered oil will enter the inner position of the oil storage tank 301 through the circulation pipe 302. When the oil is filled to a certain amount, the filling will stop, and then the electromagnetic air control valve 318 will be closed. At this time, the air outlet fan 313 is controlled to start, so as to control the air outlet fan 313 to extract air outward. At this time, the air inside the oil storage tank 301 will be extracted from the inner side of the air outlet pipe 304. At this time, under the elastic action of the silica gel pad 307, the gas will be discharged from the exhaust pipe 314. Then, under the action of the external pressure, the movable plate 312 will overcome the elastic force of the tightening spring 311 and press tightly against the outside of the pressure relief groove 310, so as to prevent air leakage and quickly extract the air inside the oil storage tank 301. And when the air extraction stops, the tightening spring 311 will bounce the movable plate 312 away. At this time, the external air pressure will press the silica gel pad 307 tightly against the outside of the air outlet pipe 304 through the pressure relief groove 310, so as to prevent air from entering the inner side of the oil storage tank 301. Then, the oil suction pump 320 is controlled to start, and then the oil is pumped outward through the flow-limiting jet head 316 and the gas distribution pipe 315. At this time, a large amount of transformer oil will be transported to the position of the oil suction pipe 319. When the operator observes the transformer oil from the observation glass 321 position, the valve outside the oil suction pipe 319 is closed, and then the nitrogen pump 323 and the nitrogen valve 324 are opened, so that nitrogen can be transported from the nitrogen pipe 322 to the gas collection pipe 317 position, and then the extracted transformer oil and nitrogen are transported to the inner side of the oil storage tank 301 through the gas distribution pipe 315 and the flow-limiting jet head 316, so as to fill the oil storage tank 301 with nitrogen, further ensuring the stability of the transformer oil inside the oil storage tank 301, further delaying the oxidation reaction of the transformer oil, and prolonging the storage time of the transformer oil, ensuring that the transformer oil can be stored for a long time;

[0068] Finally, after the transformer oil in one of the oil storage tanks 301 is full, it can be moved into the warehouse through the moving wheels 404. Then, insert the positioning magnet 410 of other full oil storage tanks 301 into the inner position of the previous positioning clamping groove 409 to fix and stabilize multiple oil storage tanks 301. When people need to use the transformer oil, they can pull the connecting base 403 to overcome the magnetic force limitation of the positioning magnet 410. Subsequently, slide the weight adjustment seat 407 on the outside of the sliding groove 406, so that the oil storage tank 301 can offset to one side inside the connecting base 403 through the positioning rod 401 and the positioning bearing 402. Then, the internal transformer oil will tend to flow to the side of the flow pipe 302. Then, people can conveniently and quickly pump out the internal transformer oil, improving the utilization efficiency of the transformer oil.

[0069] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
