Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to an inspection device and method for transformer production. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). With the development and progress of society, there are many types and models of transformers, and their application areas are becoming more and more extensive. Therefore, the quality requirements for transformers are becoming more and more stringent. After the transformer is produced, it is necessary to perform a withstand voltage test on each pin circuit of the transformer.

[0003] However, in the process of inspecting the transformer, multiple tests are required, which not only consumes a lot of labor but also reduces the detection efficiency. After the pins of the transformer are connected to the detection device, the pins are thin, which may cause the transformer to deviate in direction when taken out, resulting in pin bending. At the same time, it is also necessary to manually wipe the surface of the transformer to ensure that there is no dust and dirt on the insulation surface of the transformer to avoid affecting the detection results, resulting in reduced detection efficiency. At the same time, the test needle used for power-on detection of the transformer is too exposed during use, which may cause the test needle to be easily damaged by external bumps during use.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Reference Figures 1 to 5 As the first embodiment of the present invention, an inspection method for an inspection device for transformer production is provided. Through the inspection method for the inspection device for transformer production, the detection efficiency is improved and auxiliary lifting, cleaning and warning are achieved.

[0031] When the transformer needs to be tested, the transformer is first placed in the withstand voltage testing mechanism 100, and the withstand voltage testing mechanism 100 is turned on to test multiple transformers. At this time, the lifting mechanism 200 is closed to allow the transformer to enter the testing position; During the process of starting the withstand voltage inspection mechanism 100, the cleaning mechanism 300 is turned on to clean the dust and dirt on the surface of the transformer, so as to prevent the dust and dirt on the surface of the transformer from affecting the transformer during the inspection process and causing inaccurate inspection results; Before testing, the protective mechanism 400 can be used to cover and protect the test needle 105, thereby increasing the service life of the test needle 105 and preventing the test needle 105 from being damaged by foreign objects and thus becoming unusable. During testing, the protective mechanism 400 will be opened to stop protection, thereby allowing the bottom of the surface of the test needle 105 to leak out and contact the transformer to be tested, thereby ensuring that the test needle 105 is protected while not affecting the test of the test needle 105; During the detection, the warning mechanism 500 will also be turned on, so that the red warning plate 503 can be observed from the outside to warn the surrounding personnel that the current transformer is being powered on for testing, to prevent the surrounding personnel from not noticing the warning and touching the energized transformer and causing personal injury. After the detection is completed, the lifting mechanism 200 will be activated to lift the transformer vertically, to prevent the transformer from deviating in direction when being taken out, causing the pins on the transformer to be bent and damaged in the detection slot 107 due to the deviation force.

[0032] Reference Figure 1 , 2, which is a second embodiment of the present invention, provides a cleaning mechanism 300, through which auxiliary cleaning is achieved.

[0033] The cleaning mechanism 300 includes a movable frame 301, the bottom of the movable frame 301 penetrates through the bottom of the test plate 104 and is slidably connected to the test plate 104, the bottom of the inner wall of the connecting frame 202 is fixedly connected with a first tension spring 302, the other end of the first tension spring 302 is fixedly connected to the top of the test plate 104, the bottom of the movable frame 301 is fixedly connected with a transmission member 303, the bottom of the transmission member 303 is provided with corresponding grooves 304, four corresponding grooves 304 are provided and are equidistantly distributed, and the inner wall of the corresponding groove 304 is fixedly connected with a wiping ring 305.

[0034] Specifically, when the test plate 104 moves downward, the test plate 104 will simultaneously drive the wiping ring 305 to clean the dust and dirt on the surface of the corresponding transformer, so as to prevent the dust and dirt on the surface of the transformer from affecting the transformer during the detection process and causing inaccurate detection results.

[0035] Furthermore, during the downward movement of the test plate 104, the test plate 104 will synchronously drive the moving frame 301 to move downward, so that the moving frame 301 drives the transmission member 303 to move downward, and then the corresponding groove 304 provided on the transmission member 303 will fit with the corresponding transformer, and then the dust and dirt on the surface of the corresponding transformer can be cleaned by using the wiping ring 305 connected to the corresponding groove 304, so as to avoid the dust and dirt on the surface of the transformer affecting the transformer during the detection process and causing inaccurate detection results. After moving downward, it will stay on the top of the support plate 106. At the same time, the test plate 104 can continue to move downward, so that the first tension spring 302 above the test plate 104 is pulled, and then the pulling force of the first tension spring 302 will be applied to the connecting frame 202 and transmitted to the transmission member 303 through the connecting frame 202, so that the transmission member 303 always remains above the support plate 106 and does not move during the detection of the transformer, so as to avoid affecting the use of the transformer. When the test plate 104 is reset, it can drive the connecting frame 202, the transmission member 303 and the wiping ring 305 to reset.

[0036] Reference Figure 1 , 2 5 is a third embodiment of the present invention, which provides a protection mechanism 400, through which auxiliary protection is achieved.

[0037] The protection mechanism 400 includes a rubber expansion sleeve 401, four rubber expansion sleeves 401 are provided and are distributed at equal distances, the top of the rubber expansion sleeve 401 is fixedly connected to the bottom of the test plate 104, a force strip 402 is provided on the rear side of the bottom of the test plate 104, the front of the force strip 402 is fixedly connected to the bottom of the back of the rubber expansion sleeve 401, a column 403 is provided on the bottom of the force strip 402, four columns 403 are provided and are distributed at equal distances, the bottom of the column 403 is fixedly connected to the top of the transmission member 303, a limiting column 404 is provided on the top of the force strip 402, four limiting columns 404 are provided and are distributed at equal distances, the top of the limiting column 404 is fixedly connected to the rear side of the bottom of the test plate 104, and the limiting column 404 corresponds to the transmission member 303.

[0038] The bottom of the limiting column 404 is fixedly connected with a magnetic block 405 , and the material of the column 403 is metal iron.

[0039] Specifically, the use of the rubber expansion sleeve 401 before detection can cover and protect the test needle 105, thereby increasing the service life of the test needle 105 and preventing the test needle 105 from being damaged and unusable due to being hit by foreign objects. The rubber expansion sleeve 401 on the surface of the test needle 105 is blocked by the column 403 so that the needle tip of the test needle 105 is exposed and contacts the top of the transformer, thereby ensuring that the test needle 105 is protected while not affecting the detection test.

[0040] Specifically, it is ensured that the bottom of the limiting column 404 can correspond to the top of the column 403 to push the stress bar 402 to improve the stability.

[0041] Furthermore, before the test, the rubber expansion sleeve 401 can be used to cover and protect the test needle 105, thereby increasing the service life of the test needle 105 and preventing the test needle 105 from being damaged and unable to be used due to collision with foreign objects. When the test plate 104 moves downward and drives the transmission member 303 to stay above the support plate 106, the column 403 on the transmission member 303 will contact the bottom of the force bar 402, and the test plate 104 is still moving downward, so that the test plate 104 drives the test needle 105 to move downward. 05 moves downward, and the rubber expansion sleeve 401 on the surface of the test needle 105 is blocked by the column 403, so that the needle tip of the test needle 105 is exposed and contacts with the top of the transformer, ensuring that the test needle 105 is protected and does not affect the detection test of the test needle 105. The force bar 402 can limit the maximum upward contraction distance of the bottom of the rubber expansion sleeve 401 through the limiting column 404, so as to avoid the situation that the rubber expansion sleeve 401 contracts too much and causes the test needle 105 to be exposed too much and easily damaged.

[0042] Furthermore, when the limiting column 404 corresponds to the column 403 through the force bar 402 and pushes the force bar 402, the limiting column 404 can use the magnetic force of the magnetic block 405 to adsorb with the top of the column 403 made of metal iron through the force bar 402, thereby ensuring that the bottom of the limiting column 404 can correspond to the top of the column 403 to push the force bar 402 to improve stability.

[0043] Reference Figures 1 to 4 , which is the third embodiment of the present invention, provides a warning mechanism 500, through which a warning is given during power-on detection.

[0044] The warning mechanism 500 includes a sliding groove 501, which is opened on the front side of the inner wall of the detection groove 107. The sliding groove 501 is internally slidably connected with a force-bearing plate 502, and the front of the force-bearing plate 502 is fixedly connected with a red warning plate 503. The top of the red warning plate 503 extends to the front side of the top of the support plate 106. An observation window 504 is inlaid on the front side of the inner wall of the sliding groove 501. The front side of the top of the force-bearing plate 502 is fixedly connected with a second tension spring 505. A plurality of second tension springs 505 are provided and are equidistantly distributed. The other end of the second tension spring 505 is fixedly connected to the front side of the top of the inner wall of the sliding groove 501. The front sides of both sides of the force-bearing plate 502 are fixedly connected with a limiting component 506.

[0045] The limiting assembly 506 includes a limiting slider 506a, the inner side of which is fixedly connected to the front sides of the force-bearing plate 502, and both sides of the inner wall of the sliding groove 501 are fixedly connected to the limiting groove 506b, and the inner wall of the limiting groove 506b is slidably connected to the surface of the limiting slider 506a.

[0046] A green elastic cloth 507 is fixedly connected to the top of the front side of the red warning plate 503 , and the bottom of the green elastic cloth 507 is fixedly connected to the front side of the top of the supporting plate 106 .

[0047] Specifically, when the red warning plate 503 moves to the inside of the sliding slot 501, surrounding personnel can observe the red warning plate 503 through the observation window 504 from the outside, so as to warn surrounding personnel that the current transformer is being powered on for testing, thereby preventing surrounding personnel from failing to notice the warning and touching the powered transformer, causing personal injury.

[0048] Specifically, by utilizing the sliding cooperation between the limiting slider 506a and the limiting groove 506b, the up and down movement of the force-bearing plate 502 can be limited in the front, back, left and right directions, thereby preventing the force-bearing plate 502 from being unstable during use.

[0049] Specifically, when the red warning plate 503 stops warning, one end of the green elastic cloth 507 moves upward and unfolds, and the right side of the red warning plate 503 is covered with the conspicuous green elastic cloth 507, thereby reminding the user that there is no transformer to be tested at present.

[0050] Furthermore, when the transformer moves to the inside of the detection slot 107 along with the lifting plate 201, the lifting plate 201 will generate downward pressure on the force-bearing plate 502, so that the force-bearing plate 502 moves downward along the inside of the sliding slot 501 to the bottom, and then the force-bearing plate 502 will drive the red warning plate 503 to move downward, so that the red warning plate 503 moves to the inside of the sliding slot 501, and then the surrounding personnel can observe the red warning plate 503 through the observation window 504 from the outside to warn the surrounding personnel that the current transformer is being powered on for testing, so as to avoid the situation where the surrounding personnel fail to notice the warning and touch the energized transformer and cause personal injury. At the same time, the second tension spring 505 is pulled to generate tension. When the transformer is lifted by the lifting plate 201, the tension of the second tension spring 505 can quickly pull the force-bearing plate 502 upward to reset, thereby stopping the warning.

[0051] Furthermore, when the force-bearing plate 502 moves up and down, the limit slider 506a will be driven to move up and down synchronously. Then, the limit slider 506a and the limit groove 506b will slide together to limit the up and down movement of the force-bearing plate 502 in the front, back, left and right directions, thereby avoiding the force-bearing plate 502 from being unstable during use.

[0052] Furthermore, when the red warning plate 503 stops warning and moves upward, one end of the green elastic cloth 507 will be moved upward and expanded, and the right side of the red warning plate 503 will be covered with the conspicuous green elastic cloth 507, so as to remind the user that there is no transformer to be tested at present. When the red warning plate 503 moves downward, the green elastic cloth 507 will be received into the sliding groove 501, so that the green elastic cloth 507 does not affect the warning effect of the red warning plate 503.

[0053] The remaining structures are the same as those of Example 2 and Example 3. Reference Figures 1 to 5 , which is the fifth embodiment of the present invention. This embodiment is different from the fourth embodiment in that: this embodiment provides an inspection device and method for transformer production.

[0054] When the transformer needs to be tested, the transformer is first placed into the test slot 107 so that the pins at the bottom of the transformer are inserted into the corresponding test slot 107, thereby connecting with the withstand voltage inspection device body 101. Then the user starts the electric telescopic rod 103 to drive the test plate 104 to move downward, and then the test plate 104 drives the test needle 105 to move downward, so that the bottom of the test needle 105 contacts the top of the transformer. Then the withstand voltage inspection device body 101 is started and the test needle 105 is turned on to energize the transformer, thereby performing electrical withstand voltage testing on multiple transformers in the current test slot 107 at the same time.

[0055] Before the transformer is tested, the transformer can be placed on the lifting plate 201, and then the electric telescopic rod 103 is started to drive the test plate 104 to move downward, which will simultaneously drive the movable sleeve 205 to move downward, and then the movable sleeve 205 pushes the movable rod 204 to move downward through the first spring 206. Since the elastic force of the first spring 206 is greater than the elastic force of the second spring 207, the movable rod 204 will drive the connecting frame 202 to move downward and squeeze the second spring 207 when moving downward. Then the connecting frame 202 will drive the lifting plate 201 to move downward, so that the transformer on the lifting plate 201 moves into the test slot 107, and then the pins at the bottom of the transformer will be vertically inserted into the corresponding test slot 107. After the lifting plate 201 moves to the bottom of the test slot 107 and the test pin 105 When continuing to move downward, the movable sleeve 205 will squeeze the first spring 206, and then the movable rod 204 will move to the inside of the movable sleeve 205 to contract, thereby ensuring that the test needle 105 can contact the top of the transformer and perform detection. After the transformer is tested, the electric telescopic rod 103 drives the test plate 104 to reset, so that the test needle 105, the movable sleeve 205, the movable rod 204 and the first spring 206 are reset. At this time, the second spring 207 will stop being squeezed and will push the connecting frame 202 to move the lifting plate 201 upward along the guide groove 203 to lift the tested transformer vertically for the user to take it, so as to avoid the direction deviation of the transformer when it is taken out, causing the pins on the transformer to be bent and damaged in the detection groove 107 due to the deviation force.

[0056] During the downward movement of the test plate 104, the test plate 104 will synchronously drive the moving frame 301 to move downward, so that the moving frame 301 drives the transmission member 303 to move downward, and then the corresponding groove 304 opened on the transmission member 303 will fit with the corresponding transformer, and then the dust and dirt on the surface of the corresponding transformer can be cleaned by using the wiping ring 305 connected to the corresponding groove 304, so as to avoid the dust and dirt on the surface of the transformer affecting the transformer during the detection process and causing inaccurate detection results. After that, it will stay on the top of the support plate 106, and the test plate 104 can continue to move downward, so that the first tension spring 302 above the test plate 104 is pulled, and then the pulling force of the first tension spring 302 will be applied to the connecting frame 202 and transmitted to the transmission member 303 through the connecting frame 202, so that the transmission member 303 always remains above the support plate 106 and does not move during the detection of the transformer, so as to avoid affecting the use of the transformer, and when the test plate 104 is reset, it can drive the connecting frame 202, the transmission member 303 and the wiping ring 305 to reset.

[0057] During the process of cleaning the transformer, the rubber sealing ring 306 can be used to seal the gap between the transformer and the inner wall of the detection groove 107 to prevent the cleaned impurities from entering the interior of the detection groove 107 and affecting the detection groove 107. When the transformer moves into the detection groove 107 and is unable to fully enter the detection groove 107 due to the influence of the rubber sealing ring 306, the thrust of the wiping ring 305 driven downward by the transmission member 303 can drive the transformer to fully enter the detection groove 107.

[0058] Before the test, the rubber expansion sleeve 401 can be used to cover and protect the test needle 105, thereby increasing the service life of the test needle 105 and preventing the test needle 105 from being damaged by foreign objects and thus becoming unusable. When the test plate 104 moves downward and drives the transmission member 303 to stay above the support plate 106, the column 403 on the transmission member 303 will contact the bottom of the force bar 402, and the test plate 104 is still moving downward, so that the test plate 104 drives the test needle 105 to move downward. The test needle 105 moves downward, and the rubber expansion sleeve 401 on the surface of the test needle 105 is blocked by the column 403, so that the needle tip of the test needle 105 is exposed and contacts with the top of the transformer, ensuring that the test needle 105 is protected while not affecting the detection test of the test needle 105, and the force bar 402 can limit the maximum upward contraction distance of the bottom of the rubber expansion sleeve 401 through the limiting column 404, to avoid the situation that the rubber expansion sleeve 401 contracts too much and causes the test needle 105 to be exposed too much and easily damaged.

[0059] When the limiting column 404 corresponds to the column 403 through the force bar 402 and pushes the force bar 402, the limiting column 404 can use the magnetic force of the magnetic block 405 to adsorb with the top of the column 403 made of metal iron through the force bar 402, thereby ensuring that the bottom of the limiting column 404 can correspond to the top of the column 403 to push the force bar 402 to improve the stability.

[0060] When the transformer moves to the inside of the detection slot 107 along with the lifting plate 201, the lifting plate 201 will generate downward pressure on the force-bearing plate 502, so that the force-bearing plate 502 moves downward along the inside of the sliding slot 501 to the bottom, and then the force-bearing plate 502 will drive the red warning plate 503 to move downward, so that the red warning plate 503 moves to the inside of the sliding slot 501, and then the surrounding personnel can observe the red warning plate 503 through the observation window 504 from the outside to warn the surrounding personnel that the current transformer is being powered on for testing, so as to avoid the situation where the surrounding personnel fail to notice the warning and touch the energized transformer and cause personal injury. At the same time, the second tension spring 505 is pulled to generate tension. When the transformer is lifted by the lifting plate 201, the tension of the second tension spring 505 can quickly pull the force-bearing plate 502 upward to reset, thereby stopping the warning.

[0061] During the up and down movement of the force-bearing plate 502, the limit slider 506a will be driven to move up and down synchronously. Then, the limit slider 506a and the limit groove 506b will slide together to limit the up and down movement of the force-bearing plate 502 in the front, back, left and right directions, thereby preventing the force-bearing plate 502 from being unstable during use.

[0062] When the red warning plate 503 stops warning and moves upward, one end of the green elastic cloth 507 will be moved upward and expanded, and the right side of the red warning plate 503 will be covered with the conspicuous green elastic cloth 507, so as to remind the user that there is no transformer to be tested at present. When the red warning plate 503 moves downward, the green elastic cloth 507 will be received into the sliding groove 501, so that the green elastic cloth 507 does not affect the warning effect of the red warning plate 503.

[0063] In summary, the transformer is inspected by opening the withstand voltage inspection mechanism 100, and the lifting mechanism 200 is closed at this time. During the process of opening the withstand voltage inspection mechanism 100, the cleaning mechanism 300 will be opened for cleaning. Before the inspection, the protection mechanism 400 will be used for protection. During the inspection, the warning mechanism 500 will be opened for warning. After the inspection is completed, the lifting mechanism 200 will be started to automatically lift out the transformer.
