Description

Technical Field

[0001] The present invention relates to the technical field of transformer detection, and particularly to a test detection device for transformer temperature rise. Background Technique

[0002] Among the multiple factors affecting the service life of a transformer, temperature can cause insulation aging, which is the most influential factor on the service life of the transformer. The heat propagation inside the transformer is uneven, so the temperature difference of each part of the transformer is very large. Regulations are made on the temperature rise of each part of the transformer under rated load, which is the allowable temperature rise of the transformer. If the transformer operates at a very high temperature for a long time, it will shorten the life of the internal insulating cardboard, make the insulating cardboard brittle, prone to cracking, lose its due insulating function, and cause accidents such as breakdown. Therefore, a temperature rise test needs to be carried out before the transformer leaves the factory. Currently, for the temperature rise test, the transformer is mainly moved into a relatively large test room for detection, and temperature sensors arranged in the test room are used to sense the temperature change.

[0003] Generally, when detecting a transformer, most often a transmission device drives the transformer to the entrance of the detection device, and then a lifting device is used to send the transformer into the detection device, so that it is not necessary to manually carry the transformer into the detection device for detection. However, after the transformer is sent into the detection device, most often the transformer is placed on a bracket on the inner wall of the bottom of the detection device. When the temperature inside the detection device rises, because the transformer is close to the bottom of the device, some areas of the transformer will be blocked, resulting in uneven heating of each part of the transformer surface and affecting the test detection result of the transformer temperature rise. Summary of the Invention

[0004] The purpose of the present invention is to provide a test detection device for transformer temperature rise to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a test detection device for transformer temperature rise, including a main body, and further including:

[0007] A lifting mechanism, the lifting mechanism is arranged on the inner wall of the main body. The lifting mechanism includes two lifting tooth racks. The two lifting tooth racks are respectively slidably connected to the left side and the right side of the main body. The bottoms of the two lifting tooth racks are fixedly connected with a sealing push plate. The top of the sealing push plate is fixedly connected with two connecting lifting frames. The bottoms of the two connecting lifting frames are fixedly connected with a closed abutting plate. The bottom of the driven closed abutting plate is fixedly connected with a connecting rotating cylinder;

[0008] The lifting mechanism is arranged at the bottom of the closed bottom plate. The lifting mechanism includes two sliding plate frames which are slidably connected to the top of the closed bottom plate, and a lifting frame is fixedly connected to the tops of the two sliding plate frames.

[0009] Further, testing and temperature-raising devices are fixedly connected to both the front and back of the main body. A temperature-raising component is arranged inside the frame of the main body. Two temperature-raising grooves are formed in the inner walls of both the front and back of the main body, and limiting sliding grooves are formed in both the front and back of the main body and are distributed between every two temperature-raising grooves.

[0010] Further, connection mechanisms are arranged on both the left and right sides of the main body. The two groups of connection mechanisms include two groups of connection columns which are respectively fixedly connected to the four corners of the outer wall of the main body. A lifting tooth column is rotatably connected to the fixed ends near the top of each group of connection columns.

[0011] Further, the lifting tooth column rotatably penetrates through the connection column. A motor is fixedly connected to the right side of the lifting tooth column and is fixedly connected to the outer wall of one of the connection columns. A support frame is fixedly connected to the bottom of the connection column, and a transmission device is fixedly connected between each group of support frames.

[0012] Further, a heat dissipation mechanism is arranged on the top of the main body. The heat dissipation mechanism includes a fixed screw rod which is fixedly connected to the top of the sealing push plate. A connection frame is fixedly connected to the top of the main body. A rotating ring sleeve is fixedly connected to the center of the top of the connection frame. A rotating screw rod sleeve is rotatably connected inside the rotating ring sleeve, and the rotating screw rod sleeve is threadedly connected to the outer wall of the fixed screw rod. A heat dissipation fan is fixedly connected to the top of the rotating screw rod sleeve.

[0013] Further, the lifting mechanism further includes a sealing frame which is fixedly connected to the top of the closed bottom plate. Anti-stripes are fixedly connected to both the left and right sides of the closed bottom plate. A pulley frame is fixedly connected to the top of the closed bottom plate. The lifting tooth frame is engaged with the lifting tooth column. The sealing push plate is slidably connected to the inner wall of the main body. The outer wall of the sealing frame is slidably connected to the inner wall of the main body. A number of pulleys are arranged inside the pulley frame.

[0014] Further, the lifting mechanism further includes two downward pressure bar frames which are respectively rotatably connected to the left and right sides of the connecting rotating cylinder. A strip-shaped hole lifting frame is fixedly connected to the bottom of the downward pressure bar frame. Connecting rotating frames are slidably connected to the opposite sides of the two strip-shaped hole lifting frames.

[0015] Further, a limiting frame is fixedly connected between the two connecting rotating frames. The top of the limiting frame abuts against the bottom of the closed bottom plate. The two sliding plate frames slidably penetrate through the closed bottom plate. The lifting frame is arranged between every two pulleys inside the pulley frame. One end of the downward pressure bar frame away from the strip-shaped hole lifting frame abuts against the bottom of the main body.

[0016] The present invention has the following beneficial effects:

[0017] (1) After the closed bottom plate drives the pulley frame and the transformer placed on the pulley frame into the main body, the top end of the lower pressure bar frame will first contact the bottom of the main body, and the end of the lower pressure bar frame away from the connecting strip hole lifting frame will abut against the bottom of the main body. When the closed bottom plate continues to rise, it presses down on the lower pressure bar frame, causing the connection between the lower pressure bar frame and the strip hole lifting frame to rotate inside the connecting rotating cylinder. The strip holes on the strip hole lifting frame will slide during the rotation of the outer wall of the connecting rotating frame, causing the end of the strip hole lifting frame away from the lower pressure bar frame to rise. Through the two groups of lower pressure bar frames and strip hole lifting frames, the connecting rotating frame and the limiting frame are lifted, driving the sliding plate frame to slide through the closed bottom plate, thereby driving the lifting frames at the tops of the two sliding plate frames to rise and pass through the gaps between every two pulleys on the pulley frame, so that the top of the lifting frame abuts against the transformer, thereby lifting the transformer, making the whole transformer located at the center of the main body, leaving a distance between the bottom of the transformer and the sealing frame and the closed bottom plate. When the temperature inside the main body rises and the temperature diffuses to the entire chamber inside the main body, the outer wall of the transformer can be in contact with the temperature inside the main body, reducing the contact dead angle between the surface of the transformer and the temperature, making all parts of the transformer surface heat more evenly, and thus improving the accuracy of the temperature rise test detection results of the transformer.

[0018] (2) In the present invention, the transformer is transported to the transmission device through an external conveyor belt and continuously transported to the pulley frame. When it reaches the pulley frame, two motors respectively drive two lifting tooth columns to rotate relatively on two groups of connecting columns, thereby driving two lifting tooth frames to rise, and at the same time driving the sealing push plate to slide upward inside the main body. When the sealing push plate rises, it drives two connecting lifting frames to slide upward inside two limiting chutes respectively, driving the closed bottom plate to rise, thereby driving the pulley frame on the top of the closed bottom plate to rise, so that the transformer to be tested on the top of the pulley frame enters the main body. When the sealing push plate reaches the top of the main body, the tops of the closed bottom plate and the abutting strip will abut against the bottom of the main body, and the sealing frame will enter the main body and fit with the inner wall of the main body. By the sealing push plate rising to the top of the main body, the top of the main body can be closed. After the test temperature rising device is started, the temperature is emitted from the inside of the temperature rising tank to the inside of the main body. By closing the top and bottom of the main body, the temperature rising efficiency inside the main body is increased when the temperature inside the main body rises, thereby improving the detection efficiency of the device.

[0019] (3) After the test and detection of the present invention are completed, when the transformer inside the main body is removed from the inside of the main body by the descent of the closed bottom plate and the pulley frame, it will simultaneously drive the sealing push plate to descend inside the main body, and push the gas with a higher temperature inside the main body out from the bottom of the main body. This avoids the difficulty of dissipating heat inside the main body due to the sealed environment inside the main body after the transformer is taken out of the main body, which may affect the next detection test. At the same time, it replaces the way of opening heat dissipation windows on the outer wall of the main body, reduces the openings on the surface of the main body, thereby increasing the sealing effect inside the main body during detection. At the same time, the heat dissipated is circulated to the external environment through the ventilation system inside the test room. When the sealing push plate descends, it drives the fixed lead screw to descend, drives the rotating lead screw sleeve to rotate inside the rotating ring sleeve, thereby driving the heat dissipation fan to rotate. After the sealing push plate descends and cold air enters the main body through the top of the main body, it quickly absorbs the heat on the inner wall of the main body. Through the rotation of the heat dissipation fan, the air flow above the sealing push plate on the inner wall of the main body is quickly circulated for heat dissipation. Thus, during the process of the sealing push plate descending and pushing the gas with a relatively high detected temperature inside the main body out from the bottom of the main body, the remaining temperature on the inner wall of the main body can be dissipated, improving the heat dissipation effect of the device, facilitating the next temperature rise test detection of the transformer, and enhancing the practicability of the device.

[0020] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Lifting mechanism 4 is arranged on the inner wall of the main body 1. The lifting mechanism 4 includes two lifting tooth racks 401 which are respectively slidably connected to the left and right sides of the main body 1. At the bottom of the two lifting tooth racks 401, there is a sealing push plate 402 fixedly connected. At the top of the sealing push plate 402, there are two connecting lifting frames 403 fixedly connected. At the bottom of the two connecting lifting frames 403, there is a closing abutment plate 404 fixedly connected. At the bottom of the driving closing abutment plate 404, there is a connecting rotating cylinder 407 fixedly connected. The lifting mechanism 4 further includes a sealing frame 405 which is fixedly connected to the top of the closing abutment plate 404. On both the left and right sides of the closing abutment plate 404, there are abutting strips 406 fixedly connected. At the top of the closing abutment plate 404, there is a pulley frame 408 fixedly connected. The lifting tooth rack 401 meshes with the lifting tooth column 204. The sealing push plate 402 is slidably connected to the inner wall of the main body 1. The outer wall of the sealing frame 405 is slidably connected to the inner wall of the main body 1. Inside the pulley frame 408, there are a number of pulleys arranged. When the pulley frame 408 at the top of the closing abutment plate 404 rises, the transformer to be tested at the top of the pulley frame 408 enters into the main body 1. When the sealing push plate 402 reaches the top of the main body 1, the top of the closing abutment plate 404 and the abutting strips 406 will abut against the bottom of the main body 1, and the sealing frame 405 will enter into the main body 1 and fit with the inner wall of the main body 1. By raising the sealing push plate 402 to the top of the main body 1, the top of the main body 1 can be sealed;

[0035] The lifting mechanism 5 is arranged at the bottom of the closed bottom plate 404. The lifting mechanism 5 includes two sliding plate frames 501. The two sliding plate frames 501 are slidably connected to the top of the closed bottom plate 404. A lifting frame 506 is fixedly connected to the tops of the two sliding plate frames 501. The lifting mechanism 5 further includes two downward pressing bar frames 504. The two downward pressing bar frames 504 are respectively rotatably connected to the left side and the right side of the connecting rotating cylinder 407. A strip hole lifting frame 505 is fixedly connected to the bottom of the downward pressing bar frame 504. Connecting rotating frames 503 are slidably connected to the opposite sides of the two strip hole lifting frames 505. A limiting frame 502 is fixedly connected between the two connecting rotating frames 503. The top of the limiting frame 502 abuts against the bottom of the closed bottom plate 404. The two sliding plate frames 501 slidably penetrate through the closed bottom plate 404. The lifting frame 506 is arranged between every two pulleys inside the pulley frame 408. One end of the downward pressing bar frame 504 away from the strip hole lifting frame 505 abuts against the bottom of the main body 1. The top end of the downward pressing bar frame 504 will first contact the bottom of the main body 1, and one end of the downward pressing bar frame 504 away from the connecting strip hole lifting frame 505 will abut against the bottom of the main body 1. When the closed bottom plate 404 continuously rises, it presses down on the downward pressing bar frame 504, causing the connection between the downward pressing bar frame 504 and the strip hole lifting frame 505 to rotate inside the connecting rotating cylinder 407. The strip holes on the strip hole lifting frame 505 will slide during the rotation of the outer wall of the connecting rotating frame 503, causing the end of the strip hole lifting frame 505 away from the downward pressing bar frame 504 to rise. Through the two groups of downward pressing bar frames 504 and strip hole lifting frames 505, the connecting rotating frame 503 and the limiting frame 502 are lifted, driving the sliding plate frames 501 to slidably penetrate through the closed bottom plate 404, thereby driving the lifting frame 506 at the tops of the two sliding plate frames 501 to rise and pass through the gaps between every two pulleys on the pulley frame 408, so that the top of the lifting frame 506 abuts against the transformer, thereby lifting the transformer;

[0036] Testing and temperature-rising devices 101 are fixedly connected to both the front and the back of the main body 1. A temperature-rising component is arranged inside the frame of the main body 1. Two temperature-rising grooves 103 are respectively formed in the inner walls of the front and the back of the main body 1. Limiting sliding grooves 102 are formed on both the front and the back of the main body 1. The limiting sliding grooves 102 are distributed between every two temperature-rising grooves 103;

[0037] Connecting mechanisms 2 are provided on both the left and right sides of the main body 1. The two groups of connecting mechanisms 2 include two groups of connecting columns 201. The two groups of connecting columns 201 are respectively fixedly connected to the four corners of the outer wall of the main body 1. A lifting tooth column 204 is rotatably connected to the fixed end near the top of the main body 1 between each group of connecting columns 201. The lifting tooth column 204 rotatably penetrates the connecting column 201. A motor 203 is fixedly connected to the right side of the lifting tooth column 204. The motor 203 is fixedly connected to the outer wall of one of the connecting columns 201. A support frame 202 is fixedly connected to the bottom of the connecting column 201. A transmission device 205 is fixedly connected between each group of support frames 202. It is continuously transmitted to the pulley frame 408 through the transmission device 205. When the pulley frame 408 reaches the pulley frame 408, the two motors 203 respectively drive the two lifting tooth columns 204 to rotate relatively on the two groups of connecting columns 201, thereby driving the two lifting tooth frames 401 to rise, and at the same time driving the sealing push plate 402 to slide upward inside the main body 1. When the sealing push plate 402 rises, it drives the two connecting lifting frames 403 to slide upward inside the two limiting chutes 102 respectively, driving the closing abutting plate 404 to rise;

[0038] A heat dissipation mechanism 3 is provided on the top of the main body 1. The heat dissipation mechanism 3 includes a fixed lead screw 301. The fixed lead screw 301 is fixedly connected to the top of the sealing push plate 402. A connecting frame 304 is fixedly connected to the top of the main body 1. A rotating ring sleeve 305 is fixedly connected to the center of the top of the connecting frame 304. A rotating lead screw sleeve 302 is rotatably connected inside the rotating ring sleeve 305. The rotating lead screw sleeve 302 is threadedly connected to the outer wall of the fixed lead screw 301. A heat dissipation fan 303 is fixedly connected to the top of the rotating lead screw sleeve 302. The heat dissipated is circulated to the external environment through the ventilation system inside the test room. When the sealing push plate 402 descends, it drives the fixed lead screw 301 to descend, driving the rotating lead screw sleeve 302 to rotate inside the rotating ring sleeve 305, thereby driving the heat dissipation fan 303 to rotate. After the sealing push plate 402 descends, the cold air enters the main body 1 through the top of the main body 1. After quickly absorbing the heat on the inner wall of the main body 1, through the rotation of the heat dissipation fan 303, the air flow above the sealing push plate 402 on the inner wall of the main body 1 is quickly circulated for heat dissipation.

[0039] During use, the transformer is transported to the transfer device 205 by an external conveyor belt and continuously transferred to the pulley frame 408 by the transfer device 205. When the pulley frame 408 reaches the pulley frame 408, two motors 203 drive two lifting tooth columns 204 to rotate relatively on two sets of connecting columns 201 respectively, thereby driving two lifting tooth frames 401 to rise. At the same time, it drives the sealing push plate 402 to slide upward inside the main body 1. When the sealing push plate 402 rises, it drives two connecting lifting frames 403 to slide upward inside two limit sliding grooves 102 respectively, driving the closing abutting plate 404 to rise, thereby driving the pulley frame 408 at the top of the closing abutting plate 404 to rise, so that the transformer to be tested at the top of the pulley frame 408 enters the main body 1. When the sealing push plate 402 reaches the top of the main body 1, the top of the closing abutting plate 404 and the abutting strip 406 will abut against the bottom of the main body 1, and the sealing frame 405 will enter the main body 1 and fit against the inner wall of the main body 1. By raising the sealing push plate 402 to the top of the main body 1, the top of the main body 1 can be sealed. After the test heating device 101 is started, the temperature is emitted from the inside of the heating tank 103 to the inside of the main body 1. By sealing the top and bottom of the main body 1, the heating efficiency inside the main body 1 is improved when the temperature inside the main body 1 rises.

[0040] Example 2, please refer to Figures 1 - 8 As shown, during use, when the closing abutting plate 404 drives the pulley frame 408 and the transformer placed on the pulley frame 408 into the main body 1, the top end of the lower pressing bar frame 504 will first contact the bottom of the main body 1, and the end of the lower pressing bar frame 504 away from the connecting strip hole lifting frame 505 will abut against the bottom of the main body 1. When the closing abutting plate 404 continues to rise, it presses down on the lower pressing bar frame 504, causing the connection between the lower pressing bar frame 504 and the strip hole lifting frame 505 to rotate inside the connecting rotating cylinder 407. The strip holes on the strip hole lifting frame 505 will slide during the rotation of the outer wall of the connecting rotating frame 503, causing the end of the strip hole lifting frame 505 away from the lower pressing bar frame 504 to rise. Through two sets of lower pressing bar frames 504 and strip hole lifting frames 505, the connecting rotating frame 503 and the limit frame 502 are lifted, driving the sliding plate frame 501 to slide through the closing abutting plate 404, thereby driving the lifting frames 506 at the tops of two sliding plate frames 501 to rise and pass through the gaps between every two pulleys on the pulley frame 408, so that the top of the lifting frame 506 abuts against the transformer, thereby lifting the transformer and making the whole transformer located at the center inside the main body 1, leaving a distance between the bottom of the transformer and the sealing frame 405 and the closing abutting plate 404. When the temperature inside the main body 1 rises and the temperature diffuses to the entire chamber inside the main body 1, the outer wall of the transformer can be in contact with the temperature inside the main body 1.

[0041] After the transformer inside the main body 1 is removed from the inside of the main body 1 by the downward movement of the closed bottom plate 404 and the pulley frame 408 when the test detection is completed, it will simultaneously drive the sealing push plate 402 to descend inside the main body 1, and push the gas with a higher temperature inside the main body 1 out from the bottom of the main body 1. This avoids the difficulty of dissipating heat inside the main body 1 due to the sealed environment inside the main body 1 after the transformer is taken out of the main body 1, which may affect the next detection test. At the same time, the heat dissipated is circulated to the external environment through the ventilation system inside the test room. When the sealing push plate 402 descends, it drives the fixed lead screw 301 to descend, driving the rotating lead screw sleeve 302 to rotate inside the rotating ring sleeve 305, thereby driving the radiator fan 303 to rotate. After the sealing push plate 402 descends and the cold air enters the inside of the main body 1 through the top of the main body 1, after quickly absorbing the heat on the inner wall of the main body 1, through the rotation of the radiator fan 303, the airflow above the sealing push plate 402 on the inner wall of the main body 1 is quickly circulated for heat dissipation. Thus, during the process of the sealing push plate 402 descending and pushing the gas with a relatively high temperature detected inside the main body 1 out from the bottom of the main body 1, the remaining temperature on the inner wall of the main body 1 can be dissipated.
