Description

Technical Field

[0001] This application relates to the field of transformer protection components, and more particularly to a silicone anti-intake component for a transformer moisture absorber. Background Technology

[0002] The working principle of a transformer dehumidifier is to regulate the intake and exhaust of air by changing the transformer oil temperature. Simultaneously, it utilizes silica gel particles in the dehumidifier to absorb moisture from the air, ensuring the insulation strength of the transformer oil. When the transformer oil temperature rises, the space inside the oil conservator decreases due to oil expansion, causing the pressure to rise. At this time, air is expelled through the dehumidifier. When the oil temperature drops, a negative pressure is created inside the oil conservator, drawing in outside air. The drawn-in air is first filtered through the transformer oil in the oil cup to remove moisture and impurities, and then the silica gel in the dehumidifier further absorbs moisture, ensuring that the air entering the transformer is dry.

[0003] As the transformer oil temperature decreases, a negative pressure forms inside the oil conservator, drawing in outside air. During this process, the dynamic force of the airflow disturbs the silica gel particles in the desiccant chamber. The dry silica gel particles are then drawn into the transformer along with the air. Once inside, these particles come into contact with the transformer oil. They may become suspended in the oil or deposit at the bottom or on the surface of other components. The presence of silica gel particles alters the purity of the transformer oil, affecting its insulation performance. Over time, this can lead to a decrease in the insulation strength of the transformer oil, increasing the risk of internal discharges, short circuits, and other faults, ultimately impacting the transformer's operation and lifespan.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a defect in the use of transformer dehumidifiers where silica particles are sucked into the transformer. Therefore, they have proposed a silica anti-sucking component for transformer dehumidifiers to solve the above problems. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a silicone anti-sucking component for a transformer moisture absorber. (See attached image.) Figure 1-3 A silicone anti-intake component for a transformer desiccant includes a desiccant body 1, an oil seal cup 2 at the bottom of the desiccant body 1, a threaded rod 3 extending into the oil seal cup 2 inside the desiccant body 1, several silicone granules 4 placed inside the desiccant body 1, a fixing groove 5 formed on the top of the outer surface of the desiccant body 1, several guide rods 6 fixedly connected to the upper and lower ends of the inner wall of the fixing groove 5, a metal filter plate 7 movably mounted on the outer surface of the guide rods 6, several filter holes 8 formed through the upper surface of the metal filter plate 7, and a through-hole formed at the center of the top of the metal filter plate 7. There is a first through hole. One side of the outer surface of the threaded rod 3 is located inside the first through hole. Several second through holes are opened through the top edge of the metal filter plate 7. One side of the outer surface of the guide rod 6 is located inside the second through hole. Springs 9 are sleeved on the outer surface of the guide rod 6 at both the upper and lower ends of the metal filter plate 7. Fixing rings 10 are fixedly installed on both sides of the top of the metal filter plate 7. Fixing holes 11 are opened through the top of the inner wall of the dehumidifier body 1 at the position corresponding to the fixing rings 10. A vibration mechanism is also provided on the outer surface of the dehumidifier body 1 to adjust the up and down movement of the metal filter plate 7.

[0021] The metal filter plate 7 has filter holes 8 with a certain pore size to block the silica gel particles 4 from passing through, allowing only air and moisture dried by the silica gel particles 4 to pass through. When the metal filter plate 7 vibrates upward, the spring 9 is compressed and stores elastic potential energy; when the metal filter plate 7 vibrates downward, the spring 9 releases elastic potential energy and pushes the metal filter plate 7 downward. The elasticity of the spring 9 also allows the metal filter plate 7 to better shake off impurities and silica gel particles 4 attached to the filter holes 8 during the vibration process.

[0022] Reference Figure 2 and Figure 3 The vibration mechanism includes a movable plate 12, which is movably installed on the top of the outer surface of the dehumidifier body 1. The two sides of the bottom end of the movable plate 12 extend through the fixing hole 11 into the dehumidifier body 1 and are fitted with limit rods 13. A bearing seat 14 is fixedly installed in the middle of one end of the movable plate 12. A movable support rod 15 is rotatably installed inside the bearing seat 14. A support frame 16 is fixedly installed on the outer surface of the dehumidifier body 1 near the movable support rod 15. A drive motor 17 is installed on the upper surface of the support frame 16. A movable disc 18 is installed at one output end of the drive motor 17. One side of the movable disc 18 is rotatably connected to one side of the movable support rod 15. A limit groove is opened in the middle of the top of the fixed ring 10. The outer diameter of the limit rod 13 is smaller than the inner diameter of the fixing hole 11. One bottom end of the limit rod 13 passes through the fixing hole 11 and is placed in the limit groove inside the fixed ring 10. The limit rod 13 and the limit groove are interlocked.

[0023] By starting the drive motor 17, the input terminal of the drive motor 17 is electrically connected to the output terminal of the external power supply, and the drive motor 17 drives the movable disk 18 to rotate. The rotation of the movable disk 18, through its connection with the movable support rod 15, causes the movable support rod 15 to rotate within the bearing seat 14. Since the movable support rod 15 is connected to the movable plate 12, the rotation of the movable support rod 15 will cause the movable plate 12 to vibrate up and down.

[0024] The implementation principle of the silica gel anti-intake component of a transformer desiccant according to an embodiment of this application is as follows: When the transformer oil temperature drops, a negative pressure is formed inside the oil conservator. When outside air is drawn into the desiccant body 1, the air first passes through the metal filter plate 7. The filter holes 8 on the metal filter plate 7 have a certain pore size, which can block the silica gel particles 4 from passing through, allowing only air and moisture dried by the silica gel particles 4 to pass through. This is because the particle size of the silica gel particles 4 is larger than the pore size of the filter holes 8, thereby effectively intercepting the silica gel particles 4 and preventing them from being drawn into the transformer.

[0025] When cleaning of the metal filter plate 7 is required, the drive motor 17 is started, which drives the movable disc 18 to rotate. The rotation of the movable disc 18, through its connection with the movable support rod 15, causes the movable support rod 15 to rotate within the bearing seat 14. Since the movable support rod 15 is connected to the movable plate 12, the rotation of the movable support rod 15 causes the movable plate 12 to vibrate up and down. The two sides of the bottom end of the movable plate 12 are connected to the fixing ring 10 at the top of the metal filter plate 7 through the limiting insert rod 13. Therefore, the vibration of the movable plate 12 is transmitted to the metal filter plate 7 through the limiting insert rod 13, causing the metal filter plate 7 to vibrate up and down on the guide rod 6.

[0026] During the up-and-down vibration of the metal filter plate 7, the springs 9, located on the outer surface of the guide rod 6 at both ends of the metal filter plate 7, play a crucial role. When the metal filter plate 7 vibrates upward, the springs 9 are compressed, storing elastic potential energy; when the metal filter plate 7 vibrates downward, the springs 9 release elastic potential energy, pushing the metal filter plate 7 downward. The presence of the springs 9 not only buffers the vibration of the metal filter plate 7 but also ensures that the metal filter plate 7 can automatically reset after vibration, maintaining its stable position under normal working conditions. At the same time, the elasticity of the springs 9 also allows the metal filter plate 7 to better shake off impurities and silica gel particles 4 adhering to the filter holes 8 during vibration, improving the cleaning effect.

[0027] During normal operation of the transformer dehumidifier, the metal filter plate 7 continuously filters the air entering the dehumidifier body 1, preventing silica gel particles 4 from being drawn into the transformer. When the filter holes 8 on the metal filter plate 7 become clogged or the filtration effect decreases due to the adhesion of impurities and silica gel particles 4, the vibration mechanism is activated to cause the metal filter plate 7 to vibrate, shaking off the impurities and silica gel particles 4 attached to the filter holes 8, achieving automatic cleaning, ensuring the filtration performance of the metal filter plate 7, thereby ensuring the normal operation of the dehumidifier, effectively preventing silica gel particles 4 from being drawn into the transformer, and ensuring the safe and stable operation of the transformer.
