Description

Technical Field

[0001] The invention relates to the technical field of transformer equipment, in particular to a transformer moisture absorption device for a transformer. Background Art

[0002] The desiccant is an auxiliary safety protection device of the transformer. The desiccant in the transformer is used to dry and remove moisture from the air. In the power industry, oil-immersed transformers are equipped with desiccant. When the air in the transformer oil storage cabinet expands or shrinks with the volume of the transformer oil, the exhausted or inhaled air must pass through the desiccant. The desiccant in the desiccant absorbs the moisture in the gas, drying and filtering the air, thereby keeping the insulating oil in the transformer tank clean.

[0003] Usually, after the device has been used for a period of time, the internal desiccant needs to be replaced. The staff needs to remove the desiccant from the part connected to the transformer, pour out the desiccant that has absorbed all the moisture, and then fill it with new desiccant. During the replacement process, the bulk desiccant may need to directly contact the humid or harmful air, which not only affects the effect of the desiccant, but also increases the health risk of the operator. Therefore, we propose a transformer desiccant device for transformers. Summary of the invention

[0004] The object of the present invention is to provide a transformer moisture absorption device for a transformer to solve the problems raised in the above background technology.

[0006] Furthermore, a filter assembly is arranged inside the filter tank, and the filter assembly includes a support frame slidably connected to the inner wall of the filter tank, and a filter plate is fixedly connected to the inner wall of the support frame.

[0007] Furthermore, the inner wall of the filter tank is fixedly connected to two slide rails, the outer surfaces of the two slide rails are slidably connected to the side walls of the support frame, the left and right sides of the support frame are provided with square grooves, and the inner walls of the two square grooves are slidably connected to limit blocks.

[0008] Furthermore, a spring is fixedly connected to one side of the two limit blocks close to the inner wall of the square groove, and a spring is fixedly connected to one side of the two springs away from the limit blocks and the inner wall of the square groove.

[0009] Furthermore, a plurality of spring sheets are fixedly connected to the inner wall of the support frame, and a limiting groove is provided on one side of the two slide rails close to the limiting block.

[0010] Furthermore, a sealing assembly is provided on the top of the box body, and the sealing assembly includes a valve seat 1 fixedly connected to the top of the box body, a slide groove is provided inside the valve seat 1, and a swivel is slidably connected to the inner wall of the slide groove.

[0011] Furthermore, the inner wall of the swivel is rotatably connected to the outer surface of the valve seat 1, the inner wall of the swivel is provided with a threaded groove, and the inner wall of the swivel is threadedly connected to the valve seat 2.

[0012] Furthermore, a groove is provided on the inner wall of the rotating ring, a sealing ring is rotatably connected to the inner wall of the groove, a sealing ring is fixedly connected to the side of the sealing ring close to the valve seat 2, a connecting pipe is fixedly connected to the top of the valve seat 2, and a rubber pad is fixedly connected to the side of the valve seat 1 close to the valve seat 2.

[0013] The present invention has the following beneficial effects: 1. In the present invention, a color-changing silica gel desiccant is installed inside the transparent tank, and the air filtered by the filter plate enters the air storage tank opened at the bottom of the cylinder, and the air enters the inside of the transparent tank through the air inlet pipe, passes through the color-changing silica gel desiccant, and the dry air generates passes through the air outlet pipe and enters the air storage tank opened at the top of the cylinder, and finally enters the connecting pipe through the valve seat, and finally is transmitted to the inside of the transformer. The color state of the color-changing silica gel desiccant inside the transparent tank can be observed through the transparent box door. When the moisture of the desiccant is saturated and needs to be replaced, the transparent box door is opened, the transparent tank is taken out from the inside of the elastic clamping block, and the transparent tank filled with new desiccant is replaced. By encapsulating the desiccant in an independent transparent tank, the replacement process is more convenient, the desiccant state of each transparent tank can be more conveniently managed, and the desiccant device is ensured to be always in the best working state. The operation and maintenance personnel only need to replace the transparent tank that has reached the saturated state, avoid filling the bulk desiccant, and reduce the contact between the desiccant and the dust in the air, without the need to disassemble and reinstall the entire desiccant device, thereby greatly improving the replacement efficiency.

[0014] 2. In the present invention, when the moisture absorption device needs to be cleaned or the filter plate needs to be replaced after being used for a long time, the handle is pulled to drive the support frame to detach from the filter slot opened at the bottom of the box body, thereby driving the filter plate to detach from the filter slot. After the filter plate is cleaned, the support frame is pushed to drive the filter plate into the filter slot. Both sides of the support frame slide on the surface of the slide rail. As the support frame moves, the limit block provided inside the support frame is squeezed and moves toward the groove opened in the support frame. The limit block squeezes the spring during the movement, and the spring is squeezed to generate elastic force. When the limit block is driven by the support frame to move to the limit slot opened in the slide rail, When the filter plate is in contact with the surface of the slide rail, the elastic force generated by the spring pushes the limit block to move to the inside of the limit groove, and a spring piece is arranged inside the support frame. When the spring piece contacts with the surface of the slide rail, it is squeezed to generate elastic force, so that the support frame is fixed inside the filter groove. Regularly cleaning the impurities and dirt on the filter plate can effectively prevent the filter plate from being blocked, and can effectively filter the dust impurities in the air, and prevent the dusty air from entering the transformer through the moisture absorption device. Dust will cause the insulating oil inside the transformer to deteriorate, and affect the normal working efficiency of the transformer. Ensure that the fluid or gas can pass smoothly, thereby improving the filtration efficiency.

[0015] 3. In the present invention, the staff connects the desiccant to the transformer, first aligns the valve seat 1 connected to the top of the box with the valve seat 2, and a rubber pad is arranged between the valve seat 2 and the nut, which increases the sealing of the connection between the valve seat 2 and the valve seat 1, and pulls the rotating ring upward to slide on the inner wall of the slide groove opened inside the valve seat 1. When the rotating ring contacts the bottom thread of the valve seat 2, the rotating ring is rotated clockwise, and the inner wall of the rotating ring is provided with a thread groove. The thread groove of the rotating ring fits with the thread on the surface of the valve seat 2. As the rotating ring rotates, the rotating ring drives the sealing ring to move to the bottom of the valve seat 2 through the sealing ring. When the sealing ring moves and contacts the valve seat 2, the connection gap between the valve seat 2 and the valve seat 1 is sealed by the sealing ring, preventing moisture, dust and other impurities in the outside air from entering the transformer. The moisture intrusion into the transformer will cause the insulating oil to get damp, thereby accelerating the aging of the insulating medium. After the sealing is enhanced, it can effectively isolate the air outside the transformer, which helps to slow down the aging process of the transformer, thereby extending its service life.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The inner wall of the swivel 403 is rotatably connected to the outer surface of the valve seat 1 401 , the inner wall of the swivel 403 is provided with a thread groove, the inner wall of the swivel 403 is threadedly connected to the valve seat 2 406 , and the thread groove of the swivel 403 fits with the thread on the surface of the valve seat 2 406 .

[0027] A groove is provided on the inner wall of the rotating ring 403, and a sealing ring 404 is rotatably connected to the inner wall of the groove. A sealing ring 405 is fixedly connected to the side of the sealing ring 404 close to the valve seat 2 406, and a connecting pipe 407 is fixedly connected to the top of the valve seat 2 406. A rubber pad 408 is fixedly connected to the side of the valve seat 1 401 close to the valve seat 2 406. When the sealing ring 405 moves and contacts the valve seat 2 406, the connecting gap between the valve seat 2 406 and the valve seat 1 401 is sealed by the sealing ring 405 to prevent moisture, dust and other impurities in the outside air from entering the transformer. After the sealing is enhanced, the air outside the transformer can be effectively isolated, which helps to slow down the aging process of the transformer and thus extend its service life.

[0028] When in use, the staff connects the desiccant to the transformer, first aligns the valve seat 1 401 connected to the top of the box body 1 with the valve seat 2 406, a rubber pad 408 is arranged between the valve seat 2 406 and the nut 409, which increases the sealing of the connection between the valve seat 2 406 and the valve seat 1 401, and pulls up the swivel 403 to slide on the inner wall of the slide groove 402 opened inside the valve seat 1 401.

When the sealing ring 405 moves and contacts the valve seat 2 406, the connecting gap between the valve seat 2 406 and the valve seat 1 401 is sealed by the sealing ring 405, preventing moisture, dust and other impurities in the outside air from entering the transformer. Moisture intrusion into the transformer will cause the insulating oil to get damp, thereby accelerating the aging of the insulating medium.

[0029] A filter plate 302 is provided at the bottom of the box body 1, which can effectively filter dust and impurities in the air and prevent dust-laden air from entering the transformer through the desiccant device.

When the stop block 305 is driven by the support frame 301 to move to the stop groove 304 opened in the slide rail 303, the elastic force generated by the spring 306 pushes the stop block 305 to move to the inside of the stop groove 304. The support frame 301 is provided with a spring piece 307 inside. The spring piece 307 is squeezed and generates elastic force when it contacts the surface of the slide rail 303, so that the support frame 301 is fixed inside the filter tank 102. Regularly cleaning the impurities and dirt on the filter plate 302 can effectively prevent the filter plate 302 from being blocked, ensuring that the fluid or gas can pass smoothly, thereby improving the filtering efficiency.

The air enters the transparent tank 203 through the air inlet pipe 204, passes through the color-changing silica gel desiccant, and the dry air passes through the air outlet pipe 205 and enters the air storage tank 105 opened at the top of the cylinder 104, and finally enters the connecting pipe 407 through the valve seat 401, and finally is transmitted to the inside of the transformer. The color-changing silica gel desiccant in the transparent tank 203 can be observed through the transparent box door 101. When the desiccant is saturated with water and needs to be replaced, open the transparent box door 101, take out the transparent tank 203 from the inside of the elastic clamping block 202, and replace the transparent tank 203 filled with new desiccant. By encapsulating the desiccant in an independent transparent tank 203, the replacement process is more convenient, and the desiccant state of each transparent tank 203 can be more conveniently managed to ensure that the desiccant device is always in the best working state. The operation and maintenance personnel only need to replace the transparent tank 203 that has reached the saturated state, without disassembling and reinstalling the entire desiccant device, which greatly improves the replacement efficiency.
