Description

Technical Field

[0001] The utility model belongs to the technical field related to power systems, and particularly relates to a locomotive transformer oil detection device. Background Art

[0002] In power systems, locomotive transformer oil serves as a crucial insulating and cooling medium, and its quality directly impacts transformer stability and lifespan. Moisture content in the oil is a key indicator of oil quality. Moisture not only reduces the oil's insulation properties and accelerates oil aging, but also promotes corrosion of metal components, impacting the transformer's proper operation. Therefore, accurate monitoring of moisture content in locomotive transformer oil is crucial for ensuring the safe operation of power systems.

[0003] Traditional methods for detecting moisture in oil often rely on offline laboratory analysis, such as the Karl Fischer method. While these methods offer high accuracy, they suffer from long testing cycles, complex operations, and the need for specialized personnel, making them difficult to meet the demands for rapid on-site testing. In recent years, with the advancement of sensor and automation control technologies, rapid on-site testing equipment has become a research hotspot, with growing demand for its application in industries such as the power industry and petrochemicals.

[0004] However, existing on-site rapid testing equipment still faces several technical bottlenecks, such as low heating efficiency, uneven water evaporation, cumbersome testing procedures, and bulky equipment, which limit its application in complex environments. In particular, issues such as uneven heat distribution within the heating hood, low water evaporation efficiency, and unstable connection between the heating hood and the testing platform affect the accuracy and convenience of testing.

[0005] In response to the above problems, this patent proposes a rapid detection device for the moisture content of locomotive transformer oil, which integrates functions such as weight measurement, heating, gas circulation drying, automatic circuit connection and data printing, aiming to provide an efficient, convenient and stable on-site detection solution for oil moisture.

The moisture content of the locomotive transformer oil is detected by the detection device, and a certain weight of locomotive transformer oil is passed through the measuring device. The measuring vessel 3 is placed on the upper end of the weighing platform 2, and the heating cover 4 is covered on the outside of the weighing platform 2 and the upper end of the measuring vessel 3. Then, the detection parameters are set through the control screen 5, and the detection is started. At the beginning of the detection process, the halogen lamp 7 serves as a heating source to quickly and evenly heat the locomotive transformer oil, so that the moisture in the locomotive transformer oil evaporates quickly. Then, the moisture content is calculated based on the reduction in the mass of the locomotive transformer oil, and the measurement parameters are printed out through the printing mechanism 6. At the same time, the gas inside the heating cover 4 can be circulated through the circulation mechanism 8 while heating, thereby accelerating the heat distribution and improving the evaporation efficiency.

[0026] Preferably, a circulation fan 9 is provided inside the lower end of the circulation mechanism 8, and a plurality of air guide channels 10 are connected to the upper sides of the front and rear ends of the circulation fan 9, and the plurality of air guide channels 10 are located inside the inner wall of the heating cover 4, and the lower ends of the plurality of air guide channels 10 are connected to air guide holes 11, and the plurality of air guide holes 11 are respectively opened inside the lower sides of the front and rear inner walls of the heating cover 4 and located outside the measuring vessel 3. A moisture absorption filter element 12 is provided inside the lower end of the circulation mechanism 8, and the moisture absorption filter element 12 is located on the lower side of the circulation fan 9. In the process of circulating the gas inside the heating cover 4, the circulation mechanism 8 can pass through the internal arrangement to circulate the gas. The circulation fan 9 sucks the gas inside the upper end of the heating cover 4 and introduces it into the multiple air guide holes 11 through multiple air guide channels 10. The multiple air guide holes 11 blow the introduced gas into the lower end of the heating cover 4, so that the gas inside the heating cover 4 circulates, thereby improving the heat distribution efficiency inside the heating cover 4 and the evaporation efficiency of the water in the locomotive transformer oil. While the gas inside the heating cover 4 circulates, the moisture absorption filter element 12 can absorb the evaporated water vapor, reduce the moisture content in the gas, and further improve the evaporation efficiency of the water in the locomotive transformer.

[0027] Preferably, magnetic electrode seats 13 are provided on the outside of the left and right ends of the weighing platform 2, and the magnetic electrode seats 13 are located inside the upper end of the base 1, and limiting holders 14 are provided on the outside of the two magnetic electrode seats 13, and conductive plates 15 are provided on the inside of the lower sides of the left and right ends of the heating cover 4.

When the heating cover 4 is covered on the outside of the weighing platform 2 and the upper end of the measuring vessel 3, the halogen lamp 7 and the circulation fan 9 can be connected to the two magnetic electrode seats 13 through the conductive plate 15 and the conductive seat 16, so that when the heating cover 4 is covered on the outside of the weighing platform 2 and the measuring vessel 3, the halogen lamp 7 and the circulation fan 9 can be connected to the circuit inside the base 1, ensuring the normal operation of the halogen lamp 7 and the circulation fan 9.

[0028] Preferably, a conductive head 17 is passed downward through the lower end of the conductive seat 16, and a compression spring 18 is provided on the upper end of the conductive head 17, and is elastically connected to the inside of the conductive seat 16 through the compression spring 18. The lower sides of the left and right ends of the heating cover 4 are fixedly connected with limit shields 19 with downward openings, and the two limit shields 19 are respectively located on the outside of the conductive sheet 15 and the conductive seat 16 on both sides, and are respectively clamped in the upper ends of the two limit clamping seats 14. An adsorption ring 20 is provided inside the outer side of the lower end of the limit shield 19, and the adsorption ring 20 is sleeved on the outside of the lower end of the conductive seat 16. An adsorption magnet 21 is provided on the upper end of the adsorption ring 20, and the adsorption magnet 21 is sleeved on the outside of the upper end of the conductive seat 16 and is slidably connected to the inside of the limit shield 19, and the limit shield 19 is away from one end of the heating cover 4 An unlocking slot 22 is provided inside, and the adsorption magnet 21 is slidably connected to the inside of the unlocking slot 22 at one end away from the heating cover 4, and protrudes outside the unlocking slot 22. Since the adsorption magnet 21 is made of magnetic material, when the adsorption magnet 21 and the adsorption ring 20 are adsorbed together, the lower end of the adsorption ring 20 can generate magnetism, so that when the heating cover 4 is covered on the outside of the upper end of the weighing platform 2, the lower end of the adsorption ring 20 can be adsorbed on the upper end of the magnetic electrode seat 13, thereby fixing the heating cover 4 and making the connection between the magnetic electrode seat 13 and the conductive seat 16 more secure. Moreover, since the lower end of the conductive seat 16 is elastically connected to the conductive head 17 through the compression spring 18, the conductive seat 16 can be more stably connected to the magnetic electrode seat 13 through the conductive head 17.

[0029] Preferably, since the adsorption magnet 21 is slidably connected to the inside of the limiting shield 19 and the unlocking slot 22, and protrudes outside the unlocking slot 22, the adsorption magnet 21 can slide upward by pulling up the part protruding outside the unlocking slot 22, so that the adsorption magnet 21 is separated from the adsorption ring 20, so that the magnetism of the lower end of the adsorption ring 20 disappears and is no longer adsorbed to the magnetic electrode seat 13, so that the adsorption ring 20 can be easily separated from the magnetic electrode seat 13, so that the heating cover 4 can be easily removed from the outside of the upper end of the weighing platform 2 and the measuring vessel 3.
