[0002] The present invention relates to the technical field of electric power equipment, and more specifically to a power grid transformer protection device. Background Art

[0003] A power transformer is a static electrical device used to convert an AC voltage (current) of a certain value into another or several different voltages (currents) of the same frequency.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 8 , a power grid transformer protection device, comprising a transformer body 1 and a cooling fan 11 arranged at the lower side of the transformer body 1, and a dehumidification component 2 is arranged inside and outside the transformer body 1; The dehumidification component 2 includes a fixed cylinder 21 fixedly connected to the four corners of the upper side of the transformer body 1, an electric push rod 22 is fixedly connected inside the fixed cylinder 21, and the telescopic ends of the front and rear corresponding electric push rods 22 are commonly fixedly connected to a connecting frame 23, and a collecting frame 24 is fixedly connected to the lower side of the connecting frame 23. A feeding port 25 is provided on the side where the two collecting frames 24 are separated from each other, and a ventilation groove 26 is provided on the outer surface of the collecting frame 24. Guide frames 27 are fixedly connected to the left and right sides inside the transformer body 1, and the collecting frame 24 moves upward and then slides and is connected inside the guide frame 27.

[0024] The shape of the collecting frame 24 matches the shape of the inside of the guide frame 27 , and the collecting frame 24 passes through the inner upper side of the transformer body 1 .

[0025] By adopting the above technical solution, during the operation of the transformer body 1, the cooling fan 11 inside the transformer body 1 is always running. In order to ensure the operating efficiency of the cooling fan 11, lubricant is usually added to the driving part of the cooling fan 11. As the temperature inside the transformer body 1 gradually rises, the moisture generated by the evaporation of the lubricant will be absorbed by the silica gel desiccant bag filled in the collection frame 24. When the silica gel desiccant bag is filled, the electric push rod 22 inside the fixed cylinder 21 is started to lift the connecting frame 23, so that the collection frame 24 fixed to the connecting frame 23 gradually moves upward. As the collection frame 24 moves inside the guide frame 27, the collection frame 24 moves upward. Slide, when the feed port 25 on the side of the collecting frame 24 is completely exposed from the inside of the guide frame 27, the staff can pour the silica gel desiccant bag into the collecting frame 24 through the feed port 25, and the moisture inside the transformer body 1 will enter the collecting frame 24 through the ventilation slot 26, and finally be absorbed by the silica gel desiccant bag. Since the silica gel desiccant bag inside the collecting frame 24 can absorb the moisture accumulated inside the transformer body 1, it avoids the evaporation of lubricant and the accumulation of water molecules generated by the excessive temperature difference between the inside and outside of the transformer body 1 in the transformer, thereby preventing the water molecules from condensing into water droplets and affecting the life and stability of metal parts.

[0026] like Figure 4 , Figure 6 and Figure 7 As shown, the inner and outer sides of the transformer body 1 are provided with a monitoring assembly 28 , and the monitoring assembly 28 includes a guide slope 281 slidably connected to the lower side of the inner part of the collection frame 24 .

[0027] A pressure sensor 283 is provided on the lower inner side of the collection frame 24, the lower side of the guide slope 281 is in squeeze contact with the upper side of the pressure sensor 283, the inclined surface of the guide slope 281 is arranged in a linear array and is rollingly connected with a first roller 282, and a warning member 284 is provided on the upper side of the transformer body 1, and the pressure sensor 283 and the warning member 284 are both electrically connected to an external power supply.

[0028] By adopting the above technical solution, as the silica gel desiccant bag is sent into the collection frame 24 and lands on the guide slope 281 inside the collection frame 24, after the silica gel desiccant bag reaches the inclined surface above the guide slope 281, the first roller 282 that can roll on the inclined surface of the guide slope 281 guides the silica gel desiccant bag, and then the silica gel desiccant bag slides to the lowest point of the slope of the guide slope 281. As the silica gel desiccant bag absorbs the moisture inside the transformer body 1, the weight of the silica gel desiccant bag itself will gradually increase. At the same time, the pressure exerted by the silica gel desiccant bag and the guide slope 281 on the pressure sensor 283 below the guide slope 281 It will also gradually increase. When the pressure on the pressure sensor 283 stops rising within a few days, it indicates that the silica gel desiccant package has failed. The pressure sensor 283 will send a signal to the controller carried inside the warning member 284, and finally the warning member 284 will be operated through the controller. After the silica gel desiccant package reaches the top of the guide slope 281, the first roller 282 will guide the silica gel desiccant package, so that the silica gel desiccant package remains stable after reaching the specified position, and at the same time monitors whether the silica gel desiccant package is invalid in real time, and issues a warning after the silica gel desiccant package fails, which effectively ensures the silica gel desiccant package's adsorption effect on the moisture inside the transformer body 1.

[0029] like Figures 1 to 4 and Figures 5 to 7 As shown, a discharge assembly 29 is provided on both the inner and outer sides of the transformer body 1 , and the discharge assembly 29 includes a discharge port 291 opened on one side of the collecting frame 24 close to the feed port 25 .

[0030] A notch 292 is provided at the center of the guide frame 27 near the discharge port 291, and the discharge port 291 is connected to the notch 292 after moving upward. A feed trough 293 is provided obliquely on the left and right sides of the transformer body 1, and the notch 292 is connected to the feed trough 293. A first movable groove 294 is provided on the inner surface of the notch 292 near the guide slope 281, and a second movable groove 295 is provided on the other side of the first movable groove 294. A fixing bar 297 is fixedly connected to one side of the collecting frame 24 near the notch 292, and a first magnetic block 298 is fixedly connected to the other side of the fixing bar 297. After the fixing bar 297 and the first magnetic block 298 move upward, they are both slidably connected in the first movable groove 294, and a metal baffle 296 is slidably connected inside the second movable groove 295, and the first magnetic block 298 is magnetically adsorbed to the metal baffle 296.

[0031] By adopting the above technical solution, when the warning member 284 issues a warning, the staff starts the electric push rod 22 to lift the connecting frame 23 upwards, and the collecting frame 24 fixed under the connecting frame 23 will slide inside the guide frame 27 at this time, and when the discharge port 291 on the side of the collecting frame 24 corresponds to the notch 292 on the side of the guide frame 27, the silica gel desiccant bag will enter the notch 292 from the discharge port 291, but will be blocked by the metal baffle 296, and while the collecting frame 24 moves upwards, the fixing bar 297 provided on the side of the collecting frame 24 with the discharge port 291 will drive the first magnetic block 298 to move upwards in the first moving groove 294, and the first magnetic block 298 adsorbs the metal baffle 296, so that the metal baffle 296 follows the first magnetic block 298 to slide in the second moving groove 295, and during the upward movement of the metal baffle 296 in the second moving groove 295, the feed chute 293 provided on the side of the transformer body 1 is connected with the notch 292, and the silica gel desiccant bag is lost. After the metal baffle 296 is removed from the obstruction, the silica gel desiccant bag will slide out of the feed chute 293. When the metal baffle 296 moves to the top of the second movable groove, the fixing bar 297 will continue to move upward inside the first movable groove 294. As the fixing bar 297 continues to move upward, the adsorption effect of the first magnetic block 298 on the metal baffle 296 gradually decreases, causing the metal plate to begin to drop according to its own weight and return to its original position. After the silica gel desiccant bag is fed into the interior of the collecting frame 24 through the feed port 25, the silica gel desiccant bag cannot enter the feed chute 293 from the notch 292, and finally falls on the top of the guide slope 281. When the silica gel desiccant bag needs to be added, the collection frame 24 that moves upward will correspond to the notch 292 due to the discharge port 291, so that the invalid silica gel desiccant bag will be discharged before the new silica gel desiccant bag enters the collection frame 24, and the new silica gel desiccant bag is prevented from being discharged, which once again ensures the adsorption effect of the silica gel desiccant bag on the moisture inside the transformer body 1.

[0032] like Figures 1 to 6 and Figure 8 As shown, a protective component 3 is provided on the upper side of the transformer body 1 , and the protective component 3 includes a hinge seat 31 fixedly connected to the outer sides of the left and right corresponding fixing cylinders 21 .

[0033] The front and rear sides of the connecting frame 23 are fixedly connected with a push plate 32, the outer side of the hinge seat 31 is fixedly connected with a cover plate 33, the front and rear corresponding opposite surfaces of the cover plates 33 are squeezed and contacted, the left and right sides of the opposite surfaces of the front and rear corresponding cover plates 33 are fixedly connected with second magnetic blocks 34, the front and rear corresponding second magnetic blocks 34 are magnetically adsorbed, the upper side of the cover plate 33 is arranged in a linear array and is rollingly connected with a second roller 35, and the push plate 32 moves upward and slides in contact with the lower side of the cover plate 33.

[0034] By adopting the above technical solution, in the process of the electric push rod 22 pushing the connecting frame 23 upward, because the pushing blocks 32 on both sides of the connecting frame 23 are always in contact with the lower side of the cover plate 33 hinged to the outer side of the fixed cylinder 21 through the hinge seat 31, as the pushing blocks 32 move upward, the two cover plates 33 originally adsorbed to each other through the second magnetic block 34 will gradually separate, and when the two cover plates 33 are in a horizontal state, the impurities originally on the cover plates 33 will fall from the cover plates 33, and after the two cover plates 33 are merged, if a bird stays on the cover plates 33, the second roller 35 above the cover plates 33 will start to roll after the bird stands up, because the cover plates 33 can shake the impurities originally on the cover plates 33 before merging to ensure the cleanliness of the surface of the cover plates 33, and the birds will not be able to stand normally due to the free rotation of the second roller 35, so as to achieve the expulsion of the birds, effectively avoid the birds from leaving feces after standing on the cover plates 33, and further prevent the bird feces from corroding the surface of the transformer body 1.

[0035] like Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, a dust blowing assembly 36 is provided on the upper side of the transformer body 1 , and the dust blowing assembly 36 includes an output pipe 361 fixedly connected to the upper side of the transformer body 1 , and the output pipe 361 is connected to the inside of the transformer body 1 .

[0036] A valve 362 is provided at the upper end of the output pipe 361, and hoses 363 are provided on both the front and rear sides of the valve 362. The hose 363 is connected to the valve 362, and the other end of the hose 363 extends to the lower side of the cover plate 33. A guide groove 364 is provided inside the cover plate 33, and the hose 363 is connected to the guide groove 364. The lower side of the second roller 35 is located inside the guide groove 364.

[0037] By adopting the above technical solution, as the cooling fan 11 inside the transformer body 1 is always running, the generated airflow will enter the valve 362 through the output pipe 361, and the hoses 363 on the front and rear sides of the valve 362 will respectively extend to the lower side of the corresponding cover plate 33 and communicate with the guide groove 364 inside the cover plate 33. As the valve 362 sends the airflow into the guide groove 364 through the hose 363, since part of the second roller 35 is inside the guide groove 364, after the airflow enters the guide groove 364, it will be discharged from the gap between the second roller 35 and the cover plate 33. When the airflow is discharged from the gap between the second roller 35 and the cover plate 33, the dust accumulated above the cover plate 33 will be blown away, and when the birds are about to stand, the blown airflow will also appear birds, so as to achieve the effect of expelling birds, further improving the effect of expelling birds.

[0038] Working principle: When the transformer body 1 is running, the temperature inside it gradually rises, and the moisture generated by the evaporation of the lubricant will be absorbed by the silica gel desiccant bag filled in the collection frame 24. When filling the silica gel desiccant bag, start the electric push rod 22 inside the fixed cylinder 21 to lift the connecting frame 23 and drive the collection frame 24 to gradually move upward. After the feed port 25 is completely exposed from the inside of the guide frame 27, the staff can pour the silica gel desiccant bag into the collection frame 24 through the feed port 25. As the silica gel desiccant bag falls on the guide slope 281 inside the collection frame 24, the first roller 282 on the inclined surface of the guide slope 281 guides the silica gel desiccant bag and slides to the lowest point of the slope of the guide slope 281, and the silica gel desiccant bag absorbs the moisture. After that, the weight of the silica gel desiccant package itself will gradually increase. At the same time, the pressure caused by the pressure sensor 283 under the guide slope 281 will also gradually increase. When the pressure on the pressure sensor 283 stops rising within a few days, it means that the silica gel desiccant package has failed. The pressure sensor 283 will send a signal to the controller carried inside the warning member 284, and finally the warning member 284 of the controller will operate. When the warning member 284 issues an alarm, the staff will start the electric push rod 22 to lift the connecting frame 23 upward. At this time, the collection frame 24 will slide upward inside the guide frame 27. When the discharge port 291 on the side of the collection frame 24 corresponds to the notch 292 on the side of the guide frame 27, the silica gel desiccant package will enter the notch 292 from the discharge port 291, but will be blocked by the gold The metal baffle 296 is blocked by the metal baffle 296, and when the collecting frame 24 moves upward, the fixing bar 297 arranged on the side of the collecting frame 24 with the discharge port 291 will drive the first magnetic block 298 to move upward in the first moving groove 294, and the first magnetic block 298 adsorbs the metal baffle 296, so that the metal baffle 296 follows the first magnetic block 298 to slide in the second moving groove 295, and during the upward movement of the metal baffle 296 in the second moving groove 295, the silica gel desiccant package loses the shielding of the metal baffle 296 and slides out of the discharge groove 293, and when the metal baffle 296 moves to the top of the second movable groove, the fixing bar 297 will continue to move upward in the first moving groove 294, and as the fixing bar 297 continues to move upward, the first magnetic block 298 The adsorption effect of 298 on the metal baffle 296 gradually decreases, causing the metal plate to begin to drop according to its own weight and return to its original position. After the silica gel desiccant bag is fed into the interior of the collecting frame 24 through the feed port 25, the silica gel desiccant bag cannot enter the discharge chute 293 from the gap 292, and finally falls on the top of the guide slope 281. In the process of the electric push rod 22 pushing the connecting frame 23 upward, because the pushing blocks 32 on both sides of the connecting frame 23 are always in contact with the lower side of the cover plate 33 hinged to the outside of the fixed cylinder 21 through the hinge seat 31, as the pushing blocks 32 move upward, the two cover plates 33 originally adsorbed to each other by the second magnetic block 34 will gradually separate. When the two cover plates 33 are in a horizontal state, the impurities originally on the cover plates 33 will fall from above the cover plates 33.After the two covers 33 are combined, if the bird stays on the cover 33, the second roller 35 on the cover 33 will start to roll after the bird stands. As the cooling fan 11 inside the transformer body 1 is always running, the airflow generated will enter the valve 362 through the output pipe 361, and then extend to the lower side of the corresponding cover 33 through the hose 363, and communicate with the guide groove 364 inside the cover 33. As the valve 362 sends the airflow into the guide groove 364 through the hose 363, part of the second roller 35 is inside the guide groove 364, and after the airflow enters the guide groove 364, it will be discharged from the gap between the second roller 35 and the cover 33.

[0039] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
