Description

Technical Field

[0001] The invention relates to a mobile assembly device for old transformers, belonging to the technical field of transformer transportation. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. Transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] During the movement of the transformer, it is necessary to ensure the stability of the transformer on bumpy roads. Therefore, a rigid connection is often used to fix the transformer. However, since bumpy roads will generate a certain impact force, a rigid connection will damage the supporting structure of the transformer, so there are some problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a mobile assembly device for old transformers, which solves the problem that in the prior art, the rigid connection method is mostly used for transportation and fixation of transformers, which may cause damage to the supporting structure of the transformer when passing through bumpy roads.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: a mobile assembly device for old transformers, including a transformer and a transportation device, the transformer including an upper fixing frame, a lower fixing frame, an iron core, a high-voltage coil, a low-voltage coil, a connecting block and a limiting block, the iron core is fixed on the lower fixing frame, the side of the iron core away from the lower fixing frame is fixed to the upper fixing frame, the high-voltage coil is sleeved on the iron core, the low-voltage coil is sleeved on the outside of the high-voltage coil and there is a gap between the high-voltage coil and the low-voltage coil, the connecting blocks are respectively arranged on the upper fixing frame and the lower fixing frame on the side facing the high-voltage coil, the limiting block is fixedly connected to the connecting block, the limiting block extends into the gap between the high-voltage coil and the low-voltage coil, the transformer is installed on the transportation device, the transportation device includes an outer shell, a flip cover, a transportation base, a buffer cavity, a buffer plate, a first energy absorption plate and an upper support gas The invention relates to a bag, wherein the outer shell is fixed on the transport base, the flip cover is hingedly arranged on the side of the outer shell away from the transport base, the outer shell and the transport base surround to form a transport space, the transformer is installed in the transport space, the flip cover controls the opening and closing of the transport space by flipping, the buffer cavity is opened on the side of the transport base facing the flip cover, the buffer plate is slidably arranged in the buffer cavity, the lower fixed frame is fixed on the buffer plate, the lower fixed frame part extends to the outside of the buffer cavity and there is a space with the outer side of the transport base, the connection between the buffer cavity and the buffer plate is sealed, the first energy absorbing plate is fixed on the side of the buffer plate away from the flip cover, the end of the first energy absorbing plate away from the buffer plate abuts against the end wall of the buffer cavity away from the flip cover, the first energy absorbing plate is in a curved structure, and an upper supporting airbag is fixedly arranged on the side of the flip cover facing the transport base, and the upper supporting airbag abuts against the upper fixed frame.

[0006] By adopting the above technical solution, when the transformer is transported and moved as a whole, the lower fixed frame is fixed on the buffer plate. When the transport base moves, vibration and shaking will occur. At this time, the transformer shakes in the transport space. At this time, the lower fixed frame generates pressure on the buffer plate, forcing the first energy absorbing plate to continue to undergo elastic deformation, so that the first energy absorbing plate absorbs the kinetic energy generated by the shaking of the transformer, which is beneficial to improving the stability of the transformer during transportation while ensuring the structural safety of the transformer.

[0007] The present invention is further configured as follows: a sliding air pressure chamber is horizontally opened on an end wall of one side of the buffer chamber away from the flip cover, one end of the first energy absorption plate away from the buffer plate extends into the sliding air pressure chamber, an intermediate air pressure chamber connected to the sliding air pressure chamber is opened in the transport base, a pressure plate is slidingly arranged in the intermediate air pressure chamber, the connection between the pressure plate and the intermediate air pressure chamber is sealed, a lower supporting air bag embedded in the transport base is fixedly arranged in the space between the lower fixed frame and the outer side surface of the transport base, the lower supporting air bag is connected to the intermediate air pressure chamber, and the pressure plate slides from the connection between the sliding air pressure chamber and the intermediate air pressure chamber toward the connection between the intermediate air pressure chamber and the lower supporting air bag.

[0008] By adopting the above technical solution, when encountering poor road conditions, the sliding amplitude of the buffer plate becomes larger, so that the deformation of the first energy absorbing plate becomes further larger, and the end of the first energy absorbing plate away from the buffer plate moves toward the sliding air pressure cavity, so that the space in the sliding air pressure cavity becomes smaller and the pressure becomes higher, and under the action of the pressure difference, the pressure plate is lifted toward the lower support airbag, so that the part of the space in the middle air pressure cavity toward the lower support airbag becomes smaller and the pressure becomes higher. At this time, the pressure in the lower support airbag becomes higher, causing the lower support airbag to expand. After the lower support airbag expands, it has a supporting effect on the lower fixed frame, and after the upper support airbag abuts against the upper fixed frame, the expansion of the lower support airbag can simultaneously limit both ends of the transformer, further reducing the shaking amplitude of the transformer, and further improving the stability of the mobile assembly device for fixing the transformer under complex road conditions.

[0009] The present invention is further configured as follows: a gas storage chamber is provided on a side of the buffer chamber away from the intermediate air pressure chamber, the gas storage chamber is filled with compressed gas, a sealed chamber is provided on a side of the buffer chamber facing the gas storage chamber, a second energy absorbing plate is fixed to one end face of a first energy absorbing plate provided on the buffer plate, the other end of the second energy absorbing plate extends into the sealed chamber, the second energy absorbing plate is bent, a first air guide channel is provided on one end face of the second energy absorbing plate extending into the sealed chamber, an air guide pipe is fixedly provided in the gas storage chamber, one end of the air guide pipe passes through the sealed chamber and extends into the first air guide channel, a connecting hole for penetrating the second energy absorbing plate is provided on a side of the first air guide channel facing the flip cover, a second air guide channel is provided on a side of the sealed chamber close to the flip cover in the transport base, and the second air guide channel is connected to the sealing The air guide passage is connected to the air chamber, and the connection between the second air guide passage and the sealed chamber is blocked and closed by the second energy absorbing plate. The connecting hole can follow the movement of the second energy absorbing plate and connect with the second air guide passage. The part of the air guide pipe located in the sealed chamber is sleeved with a reset spring, and the two ends of the reset spring are respectively abutted against the inner wall of the sealed chamber and the end face of the second energy absorbing plate. An intermediate air storage chamber located on the side of the lower supporting airbag is opened in the transport base, and a third air guide passage is connected between the intermediate air storage chamber and the second air guide passage. An exhaust passage is penetrated through the transport base on the side of the intermediate air storage chamber facing the flip cover, and a pipe joint is fixedly provided on the exhaust passage, and a closing structure for closing the exhaust passage is provided in the exhaust passage, and a preset pipe is sleeved on the pipe joint, and the end of the preset pipe away from the pipe joint is connected with the upper supporting airbag.

[0010] The present invention is further configured as follows: a closing structure includes a sealing cavity, a sealing sliding groove, a sealing spring, a sealing plate and an air guide hole, the sealing sliding groove is opened on a side of the transport base facing the flip cover and is located on a side of the lower supporting airbag facing the middle air storage cavity, the sealing plate is arranged in the sealing sliding groove, the sealing plate slides from the lower supporting airbag toward the middle air storage cavity, the sealing plate abuts against the outer side of the lower supporting airbag, the sealing cavity is arranged on a side of the sealing sliding groove away from the lower supporting airbag and the sealing cavity is connected with the sealing sliding groove, the side of the sealing cavity away from the sealing sliding groove is connected with the exhaust channel, the sealing plate portion extends into the sealing cavity and blocks the exhaust channel, the air guide hole is opened at a part of the sealing plate located in the sealing cavity and passes through the sealing plate, the air guide hole can be connected with the exhaust channel, the sealing spring is arranged in the sealing sliding groove, one end of the sealing spring abuts against the inner wall of the sealing sliding groove, the other end of the sealing spring abuts against the sealing plate, and the elastic direction of the sealing spring is the same as the sliding direction of the sealing plate.

[0011] By adopting the above technical solution, when the road condition is poor, the sliding amplitude of the buffer plate becomes larger, thereby lengthening the length of the second energy absorbing plate entering the sealed cavity. At this time, the connecting hole follows the movement of the second energy absorbing plate and is connected to the second air guide channel. At this time, the compressed gas in the gas storage cavity is introduced into the first air guide channel through the air guide pipe, and enters the third air guide channel through the connecting hole and the second air guide channel. The third air guide channel introduces the gas into the middle air storage cavity for storage. At this time, the closed structure restricts the gas in the middle air storage cavity and cannot be discharged. The sliding amplitude of the buffer plate is further increased, causing the lower support airbag to expand through the above process. Due to the large weight of the transformer, the lower support airbag expands toward the sealing plate after supporting the transformer, thereby pushing The dynamic sealing baffle moves, and when the sealing baffle drives the air guide hole to connect with the exhaust channel, the gas in the middle air storage chamber enters the preset pipe through the exhaust channel and finally enters the upper support airbag. After the transformer shakes vertically, the transformer moves away from the upper support airbag and a gap is generated, and the restrictive effect of the upper support airbag on the transformer is reduced. After the upper support airbag expands, the upper support airbag fills the gap generated by the vertical shaking of the transformer. At this time, the upper support airbag can continue to maintain contact with the transformer, thereby absorbing the impact force generated when the transformer shakes toward the flip cover, avoiding direct collision between the transformer and the flip cover, which is beneficial to further protect the transformer from damage during transportation and improve the transportation stability of the transformer.

[0012] The present invention is further configured as follows: a locking block fixedly connected to the transport base is provided on a side of the buffer cavity facing the flip cover, the locking block abuts against a portion of the lower fixed frame extending to the outside of the buffer cavity, an adjusting sliding groove is provided on a side of the locking block away from the transport base, a locking channel is provided through an end wall of the adjusting sliding groove away from the transformer, the extending directions of the adjusting sliding groove and the locking channel are the same, a sliding block is slidably provided in the adjusting sliding groove, a first locking column extending to the outside of the locking block through the locking channel is fixedly provided on the sliding block, a first locking column is threadedly connected to an end of the first locking column located outside the locking block with a first locking nut, a positioning block is provided on a side of the sliding block facing the flip cover, a second locking column is penetrated through the positioning block, an end of the second locking column close to the transport base penetrates the positioning block and is fixedly connected to the sliding block, an end of the second locking column away from the transport base penetrates the positioning block and extends to the outside of the positioning block, an end of the second locking column away from the transport base is threadedly connected with a second locking nut, the second locking nut abuts against the positioning block, the positioning block can abut against a connecting block located between the lower fixed frame and the high-voltage coil, and the positioning block abuts against the connecting block to limit the horizontal movement of the connecting block.

[0013] By adopting the above technical solution, when the old transformer needs to be disassembled and moved, the first locking column is held to adjust the sliding block to slide in the adjusting sliding groove to achieve the purpose of adjusting the position of the positioning block, and the positioning block is rotated along the second locking column to adjust the angle of the positioning block so that the positioning block can contact the surface of the connecting block. When the position of the positioning block is adjusted, the second locking nut and the first locking nut are rotated to lock the sliding block and the positioning block under the action of the threaded structure so that the positioning block cannot move. At this time, the positioning block is in contact with the surface of the connecting block, and the positioning block marks the position of the connecting block. After the transformer is disassembled, the upper fixing frame, the lower fixing frame, the iron core, the high-voltage coil, and the low-voltage coil are The high-voltage coil and the connecting block are removed and transported separately. After arriving at the transportation site, the transformer needs to be assembled. At this time, since the positioning block marks the position of the connecting block, during the installation of the connecting block, after the high-voltage coil and the low-voltage coil are sleeved on the iron core, the limit block needs to be inserted into the gap between the high-voltage coil and the low-voltage coil. At this time, the position of the connecting block is determined by allowing the connecting block to abut against the positioning block and fixing the connecting block to the lower fixing frame, and then the high-voltage coil and the low-voltage coil are sleeved in turn. At this time, the limit block is inserted into the gap between the high-voltage coil and the low-voltage coil, and there is no need to manually proofread the position of the connecting block for a long time, thereby improving the assembly efficiency of the transformer.

[0014] The present invention is further configured as follows: a connecting column is provided on the side of the positioning block facing the transformer, the connecting column is axially inserted into the positioning block and plugged into the positioning block, an auxiliary block is fixedly provided on the end of the connecting column away from the positioning block, a recovery chamber is provided in the auxiliary block, the recovery chamber penetrates the auxiliary block toward the side of the flip cover to form a through opening, the through opening is aligned with the gap between the high-voltage coil and the low-voltage coil, a moving block is slidably provided in the recovery chamber, the horizontal extension direction of the moving block is the same as the circumferential direction of the high-voltage coil and the low-voltage coil, the moving block slides toward the direction of the through opening of the auxiliary block, a pressing groove is provided on the side of the auxiliary block away from the connecting block, the pressing groove extends toward the flip cover, and the inner edge of the pressing groove A pressing block is provided for sliding in the extension direction of the pressing slide groove, one end of the pressing block is fixedly connected to the moving block, and the other end of the pressing block extends to the outside of the auxiliary block. The moving block is located at the vertical end faces on both sides of the gap between the high-voltage coil and the low-voltage coil, and grooves are provided. An elastic plate is fixedly provided in the groove, and the horizontal extension direction of the elastic plate is the same as that of the moving block. The end of the elastic plate facing the flip cover can follow the movement of the moving block and extend into the gap between the high-voltage coil and the low-voltage coil. The two elastic plates are bent in directions away from each other, and two flexible sheets are fixedly provided on a side of the moving block facing the flip cover, and the ends of the two flexible sheets away from the moving block are respectively fixed to the ends of the two elastic plates facing the flip cover.

[0015] By adopting the above technical solution, when the transformer is in use, an arc is easily generated in the gap between the high-voltage coil and the low-voltage coil. At this time, a cylindrical insulating sheet needs to be inserted into the gap to prevent the generation of arc from affecting the use of the transformer. At this time, the end of the insulating sheet needs to be inserted into the limit block so that the limit block restricts the insulating sheet. During the installation of the insulating sheet, the upper fixing frame is not installed. The insulating sheet is directly inserted into the gap at the end of the high-voltage coil and the low-voltage coil. The pressing block is manually pushed toward the direction of the flip cover to make the moving block move toward the direction of the gap between the high-voltage coil and the low-voltage coil. At this time, the elastic plate enters the gap between the high-voltage coil and the low-voltage coil. When the moving block moves out of the auxiliary block, the auxiliary block releases the restriction on the elastic plate. The two elastic plates are bent toward the direction of the high-voltage coil and the low-voltage coil respectively and are aligned with the high-voltage coil and the low-voltage coil. The pressure coil is abutted, and the flexible sheet is extended and deformed and then bends with the elastic plate. At this time, with the insertion of the insulating sheet, the end of the insulating sheet abuts against the flexible sheet, and under the guidance of the flexible sheet, it finally moves between the two flexible sheets and abuts against the moving block. Since the horizontal extension direction of the moving block is along the circumferential direction of the high-voltage coil and the low-voltage coil, the horizontal extension direction of the limit block is the same as the circumferential direction of the high-voltage coil and the low-voltage coil. Therefore, at this time, the insulating sheet is restricted by the flexible sheet and has a consistent horizontal extension arc with the limit block. As the insulating sheet further presses the moving block, the insulating sheet is gradually inserted into the plug-in slot of the limit block, and the end of the insulating sheet is inserted into the plug-in slot and plugged into the limit block, thereby completing the restriction of the insulating sheet by the limit block. In this way, there is no need to manually align the insulating sheet and the limit block, which reduces the installation steps and is conducive to improving the assembly efficiency of the transformer.

[0016] The present invention is further configured as follows: a first slot located between two flexible sheets is opened on one end surface of the moving block facing the flip cover, the first slot extends in the horizontal extension direction of the moving block, a second slot and a third slot are respectively provided at both ends of the extension direction of the first slot, the second slot is located on a side of the first slot close to the connecting block, and the third slot is located on a side of the first slot away from the connecting block.

[0017] The present invention is further configured as follows: a flip cavity is opened on the opposite end wall within the third slot, a clamping plate is rotatably arranged in the flip cavity, the rotation axis of the clamping plate extends in a horizontal direction, one end of the clamping plate away from the flip cover is bent toward the third slot, and a friction layer is fixed to one end of the clamping plate facing the flip cover and one side facing the third slot.

[0018] By adopting the above technical solution, when the insulating sheet is an unfolded rectangular sheet, the insulating sheet is first bent into a cylindrical shape, at which time the two ends of the insulating sheet are abutted, and then the insulating sheet is inserted into the gap between the high-voltage coil and the low-voltage coil through the above process, and the abutment of the insulating sheet is located between two adjacent connecting blocks on one side. At this time, the insulating sheet is guided to the opening of the first slot by the flexible sheet, and as the insulating sheet continues to move, the insulating sheet is finally inserted into the first slot, and at the same time, the insulating sheet is inserted into the third slot and the second slot. At this time, the insulating sheet located in the third slot abuts against the part of the clamping plate bent into the third slot, and the insulating sheet continues to move to press the abutted end of the clamping plate into the flip cavity. At this time, one end of the clamping plate with a friction layer enters the third slot and abuts against the insulating sheet. At this time, the clamping plate has a clamping effect on the insulating sheet to ensure that the insulating sheet will not unfold. After the connecting block between the upper fixed frame and the high-voltage coil is installed, the connecting blocks located at both ends of the high-voltage coil and the low-voltage coil jointly restrict the insulating sheet. At this time, the insulating sheet will remain stable, so there is no need for the installer to hold the insulating sheet to keep it stable, thereby reducing the difficulty of assembling the transformer.

[0019] The beneficial effect of the present invention is that when the transformer is transported and moved as a whole, the lower fixed frame is fixed on the buffer plate. When the transport base moves, vibration and shaking will occur. At this time, the transformer shakes in the transport space. At this time, the lower fixed frame generates pressure on the buffer plate, forcing the first energy absorbing plate to continue to undergo elastic deformation, so that the first energy absorbing plate absorbs the kinetic energy generated by the shaking of the transformer, which is beneficial to improving the stability of the transformer during transportation while ensuring the structural safety of the transformer.

The end of the second locking column 27 close to the transport base 43 penetrates the positioning block 26 and is fixedly connected to the sliding block 23. The end of the second locking column 27 away from the transport base 43 penetrates the positioning block 26 and extends to the outside of the positioning block 26. The end of the second locking column 27 away from the transport base 43 is threadedly connected with a second locking nut 28, and the second locking nut 28 abuts against the positioning block 26. The positioning block 26 can abut against a connecting block 15 located between the lower fixing frame 11 and the high-voltage coil 13, and the positioning block 26 abuts against the connecting block 15 to limit the horizontal movement of the connecting block 15.

[0027] like Figure 5 As shown, a connecting column 29 is provided on the side of the positioning block 26 facing the transformer, and the connecting column 29 is axially inserted into the positioning block 26 and plugged into the positioning block 26. An auxiliary block 30 is fixedly provided on the end of the connecting column 29 away from the positioning block 26, and a recovery chamber 31 is provided in the auxiliary block 30. The recovery chamber 31 penetrates the auxiliary block 30 toward the side of the flip cover 18 to form a through opening, and the through opening is aligned with the gap between the high-voltage coil 13 and the low-voltage coil 14. A moving block 32 is slidably provided in the recovery chamber 31, and the horizontal extension direction of the moving block 32 is the same as the circumferential direction of the high-voltage coil 13 and the low-voltage coil 14. The moving block 32 slides toward the direction of the through opening of the auxiliary block 30, and a pressing groove 42 is provided on the side of the auxiliary block 30 away from the connecting block 15. The pressing groove 42 extends toward the flip cover 18, and the pressing groove 42 is pressed along the pressing groove 42. A pressing block 41 is slidably arranged in the extension direction of the groove 42, one end of the pressing block 41 is fixedly connected to the moving block 32, and the other end of the pressing block 41 extends to the outside of the auxiliary block 30. The moving block 32 is located in the gap between the high-voltage coil 13 and the low-voltage coil 14. The vertical end faces are provided with grooves 35 on both sides, and an elastic plate 36 is fixedly arranged in the groove 35. The horizontal extension direction of the elastic plate 36 is the same as that of the moving block 32. The end of the elastic plate 36 facing the flip cover 18 can follow the movement of the moving block 32 and extend into the gap between the high-voltage coil 13 and the low-voltage coil 14. The two elastic plates 36 are bent in a direction away from each other. Two flexible sheets 37 are fixedly arranged on the side of the moving block 32 facing the flip cover 18. The ends of the two flexible sheets 37 away from the moving block 32 are respectively fixed to the ends of the two elastic plates 36 facing the flip cover 18. In the initial state, the moving block 32 is located in the auxiliary block 30. At this time, the auxiliary block 30 restricts the bending of the elastic plate 36 so that the elastic plate 36 cannot be bent.

[0028] like Figure 6 As shown, a first slot 33 located between two flexible sheets 37 is provided on one end face of the moving block 32 facing the flip cover 18. The first slot 33 extends in the horizontal extension direction of the moving block 32. The extension length of the first slot 33 is less than the extension length of the moving block 32. A second slot 34 and a third slot 38 are respectively provided at both ends of the extension direction of the first slot 33. The openings of the second slot 34 and the third slot 38 are larger than the opening of the first slot 33 to facilitate the insertion of the insulating sheet. The second slot 34 is located on the side of the first slot 33 close to the connecting block 15, and the third slot 38 is located on the side of the first slot 33 away from the connecting block 15.

The rotation axis of the clamping plate 40 extends in the horizontal direction. The end of the clamping plate 40 away from the flip cover 18 is bent toward the third slot 38. The rotation axis of the clamping plate 40 is located at the bending part of the clamping plate 40. A friction layer is fixed on the side of the clamping plate 40 facing the flip cover 18 and facing the third slot 38.

[0029] When the transformer is transported and moved as a whole, the lower fixing frame 11 is fixed on the buffer plate 45. When the transport base 43 moves, vibration and shaking will occur. At this time, the transformer shakes in the transport space. At this time, the lower fixing frame 11 exerts pressure on the buffer plate 45, forcing the first energy absorbing plate 46 to continue to undergo elastic deformation, so that the first energy absorbing plate 46 absorbs the kinetic energy generated by the shaking of the transformer, which is beneficial to improving the stability of the transformer during transportation.

[0030] When encountering poor road conditions, the sliding amplitude of the buffer plate 45 increases, causing the deformation of the first energy absorbing plate 46 to further increase. The end of the first energy absorbing plate 46 away from the buffer plate 45 moves toward the sliding air pressure chamber 48, causing the space in the sliding air pressure chamber 48 to become smaller and the pressure to increase. Under the action of the pressure difference, the pressure plate 50 is lifted toward the lower support airbag 51, thereby causing the part of the space in the middle air pressure chamber 49 toward the lower support airbag 51 to become smaller and the pressure to increase. At this time, the pressure in the lower support airbag 51 increases, causing the lower support airbag 51 to expand. After the lower support airbag 51 expands, it supports the lower fixed frame 11, and after the upper support airbag 66 abuts against the upper fixed frame 10, the expansion of the lower support airbag 51 can simultaneously limit both ends of the transformer, further reducing the shaking amplitude of the transformer, and further improving the stability of the mobile assembly device for fixing the transformer under complex road conditions.

[0031] When the road condition is poor, the sliding amplitude of the buffer plate 45 becomes larger, so that the length of the second energy absorbing plate 47 entering the sealed cavity 54 becomes longer. At this time, the connecting hole 57 follows the movement of the second energy absorbing plate 47 and is connected to the second air guide channel 58. At this time, the compressed gas in the gas storage cavity 52 is introduced into the first air guide channel 56 through the air guide pipe 53, and enters the third air guide channel 59 through the connecting hole 57 and the second air guide channel 58. The third air guide channel 59 introduces the gas into the intermediate gas storage cavity 60 for storage. At this time, the closed structure restricts the gas in the intermediate gas storage cavity 60 and cannot be discharged. The sliding amplitude of the buffer plate 45 becomes larger, causing the lower support airbag 51 to expand through the above process. Due to the heavy weight of the transformer, the lower support airbag 51 expands toward the direction of the sealing plate 64 after supporting the transformer, thereby pushing The sealing plate 64 moves, and when the sealing plate 64 drives the air guide hole 69 to connect with the exhaust channel 68, the gas in the middle air storage chamber 60 enters the preset pipe 65 through the exhaust channel 68, and finally enters the upper support airbag 66. After the transformer shakes vertically, the transformer moves away from the upper support airbag 66 and a gap is generated. The restrictive effect of the upper support airbag 66 on the transformer is reduced. After the upper support airbag 66 expands, the upper support airbag 66 fills the gap generated when the transformer shakes vertically. At this time, the upper support airbag 66 can continue to maintain contact with the transformer, thereby absorbing the impact force generated when the transformer shakes toward the flip cover 18, avoiding direct collision between the transformer and the flip cover 18, which is beneficial to further protect the transformer from damage during transportation and improve the transportation stability of the transformer.

[0032] When the old transformer needs to be disassembled and moved, the sliding block 23 is adjusted to slide in the adjusting sliding groove 21 by holding the first locking column 24 to achieve the purpose of adjusting the position of the positioning block 26. The positioning block 26 is rotated along the second locking column 27 to adjust the angle of the positioning block 26 so that the positioning block 26 can contact the surface of the connecting block 15. When the position of the positioning block 26 is adjusted, the second locking nut 28 and the first locking nut 25 are rotated to complete the locking of the sliding block 23 and the positioning block 26 under the action of the threaded structure, so that the positioning block 26 cannot move. At this time, the positioning block 26 is in surface contact with the connecting block 15, and the positioning block 26 marks the position of the connecting block 15. After the transformer is disassembled, the upper fixing frame 10, the lower fixing frame 11, the iron core 12, the high-voltage coil 13, and the low-voltage coil 1 4 and the connecting block 15 are removed and transported separately. After arriving at the transportation location, the transformer needs to be assembled. At this time, since the positioning block 26 marks the position of the connecting block 15, during the installation of the connecting block 15, after the high-voltage coil 13 and the low-voltage coil 14 are sleeved on the iron core 12, the limit block 16 needs to be inserted into the gap between the high-voltage coil 13 and the low-voltage coil 14. At this time, the connecting block 15 is abutted against the positioning block 26, and the connecting block 15 is fixed to the lower fixing frame 11, so as to determine the position of the connecting block 15, and then the high-voltage coil 13 and the low-voltage coil 14 are sleeved in turn. At this time, the limit block 16 is inserted into the gap between the high-voltage coil 13 and the low-voltage coil 14, and there is no need to manually calibrate the position of the connecting block 15 for a long time, thereby improving the assembly efficiency of the transformer.

[0033] When the transformer is in use, an arc is easily generated in the gap between the high-voltage coil 13 and the low-voltage coil 14. At this time, a cylindrical insulating sheet needs to be inserted into the gap to prevent the generation of arcs from affecting the use of the transformer. At this time, the end of the insulating sheet needs to be inserted into the limit block 16 so that the limit block 16 restricts the insulating sheet. During the installation of the insulating sheet, the upper fixing frame 10 is not installed. The insulating sheet is directly inserted into the gap at the end of the high-voltage coil 13 and the low-voltage coil 14. The pressing block 41 is manually pushed toward the flip cover 18 to move the moving block 32 toward the gap between the high-voltage coil 13 and the low-voltage coil 14. At this time, the elastic plate 36 enters the gap between the high-voltage coil 13 and the low-voltage coil 14. When the moving block 32 moves out of the auxiliary block 30, the auxiliary block 30 releases the restriction on the elastic plate 36. The two elastic plates 36 are bent toward the high-voltage coil 13 and the low-voltage coil 14 respectively and are aligned with the high-voltage coil 13 and the low-voltage coil 14. The flexible sheet 37 is stretched and deformed, and then bends along with the elastic sheet 36. At this time, as the insulating sheet is inserted, the end of the insulating sheet abuts against the flexible sheet 37, and under the guidance of the flexible sheet 37, it finally moves between the two flexible sheets 37 and abuts against the moving block 32. Since the horizontal extension direction of the moving block 32 is along the circumferential direction of the high-voltage coil 13 and the low-voltage coil 14, the horizontal extension direction of the limit block 16 is the same as the circumferential direction of the high-voltage coil 13 and the low-voltage coil 14. Therefore, at this time, the insulating sheet is restricted by the flexible sheet 37 and has the same horizontal extension arc as the limit block 16. As the insulating sheet further presses the moving block 32, the insulating sheet is gradually inserted into the plug-in slot of the limit block 16. The end of the insulating sheet is inserted into the plug-in slot and plugged into the limit block 16, completing the restriction of the insulating sheet by the limit block 16. In this way, there is no need to manually align the insulating sheet with the plug-in slot on the limit block 16, which reduces the installation steps and is conducive to improving the assembly efficiency of the transformer.

[0034] When the insulating sheet is an unfolded rectangular sheet, the insulating sheet is first bent into a cylindrical shape, at which point the two ends of the insulating sheet are abutted, and then the insulating sheet is inserted into the gap between the high-voltage coil 13 and the low-voltage coil 14 through the above process, and the abutment of the insulating sheet is located between two adjacent connecting blocks 15 on one side. At this time, the insulating sheet is guided to the opening of the first slot 33 by the flexible sheet 37. As the insulating sheet continues to move, the insulating sheet is finally inserted into the first slot 33, and at the same time, the insulating sheet is inserted into the third slot 38 and the second slot 34. At this time, the insulating sheet located in the third slot 38 and the clamping plate 40 are bent into the third slot 38, the insulating sheet continues to move to press the end of the clamping plate 40 that is abutted into the flip cavity 39. At this time, the end of the clamping plate 40 with the friction layer enters the third slot 38 and abuts against the insulating sheet. At this time, the clamping plate 40 has a clamping effect on the insulating sheet to ensure that the insulating sheet will not unfold. After the connecting block 15 between the upper fixing frame 10 and the high-voltage coil 13 is installed, the connecting blocks 15 located at both ends of the high-voltage coil 13 and the low-voltage coil 14 jointly restrict the insulating sheet. At this time, the insulating sheet will remain stable, so there is no need for the installer to hold the insulating sheet to stabilize it, which reduces the difficulty of assembling the transformer.

[0035] When the insulating sheet abuts against the limit block 16, the insulating sheet cannot move further. At this time, the hand-held pressing block 41 presses the moving block 32 in the direction away from the flip cover 18, so that the moving block 32 is retracted into the auxiliary block 30. At this time, the auxiliary block 30 presses the bent elastic plate 36 to restore it to an upright state, and the insulating sheet is disconnected from the moving block 32, completing the resetting of the moving block 32.
