Description

[0001] The invention relates to the technical field of transformer production, and in particular to a transformer winding drying constant voltage device. Background Art

[0002] Transformer winding refers to the circuit part of the transformer, which is wound by copper wire or aluminum wire with high conductivity. It is used in power systems. Transformer winding should have sufficient insulation strength, mechanical strength and heat resistance. Transformer winding is usually divided into two types: layer type and pancake type. Transformer winding is the core component of the transformer. It needs to be dried during the production and processing of transformer winding. Before drying, the transformer winding needs to be compacted so that the transformer winding constant pressure device will put the transformer into a constant pressure drying box for constant pressure drying. However, when the transformer is compacted, it is easy to loosen, resulting in loose compaction, causing the transformer to shift during subsequent drying, resulting in damage to the transformer due to displacement during the drying process. When the transformer is compacted, the force at the extrusion position is uneven due to insufficient force, which makes the transformer winding easy to be structurally unstable when compacted, reducing the quality of the transformer winding. It is not easy to dry the transformer windings with different additions during drying, resulting in incomplete drying of the transformer winding.

[0003] To sum up, when the transformer is compressed, the force at the extrusion position is not uniform due to insufficient force, which makes the transformer winding easily unstable when compressed. It is not easy to dry the transformer windings with different additions during drying, which makes the transformer winding easily incompletely dried. Summary of the invention

[0015] The present invention provides a transformer winding drying constant voltage device. It has the following beneficial effects: 1. The transformer winding drying constant pressure equipment is provided with a dryer, an air supply box, and a pressing component. The dryer is located inside the base below the supporting component, so that the heat generated by the dryer dries the transformer winding from bottom to top, and the heat can enter the supporting component to dry the bottom of the transformer winding when the heat circulates, thereby ensuring that the transformer winding is thoroughly dried. The air supply box delivers wind when the sealing box is separated from the base, thereby accelerating the air circulation at the transformer winding position. The number of supports placed on the supporting component can be adjusted according to the volume of the transformer winding, ensuring that the pressing component fully contacts the transformer winding when it descends, so that the pressing component is not easily displaced when tightening the transformer winding.

[0016] 2. The transformer winding drying constant pressure equipment, through the adjusting rod receiving thrust to rotate clockwise on the sealing box, makes the adjusting rod drive the connecting frame to descend, so that the adjusting rod rotates to adjust the activity space inside the sealing box, and the connecting frame moves along the inner wall of the sealing box when it is lifted or lowered, so that the connecting frame drives the fixed shell to move smoothly when it is lifted or lowered, and prevents the connecting frame from tilting during the movement inside the sealing box, so as to ensure the pressing effect of the pressing plate on the fixed shell on the transformer winding.

[0017] 3. The transformer winding drying constant pressure equipment corresponds to the placement position of the transformer winding on the supporting component when the pressing plate is lifted and lowered, so that the pressing plate can press the transformer winding during the descending process to prevent the transformer winding from shifting on the supporting component and falling. As the lifting and lowering pressure block gradually approaches the pressing plate, the distance between the pressing plate and the transformer winding is reduced, so that the lifting and lowering pressure block and the pressing plate cooperate to press the transformer winding.

[0018] 4. The transformer winding drying constant pressure equipment supports the fixed shell by reinforcing columns and inner spacers, so as to maintain the movable space inside the fixed shell and prevent the fixed shell from changing and causing the pressing plate to tilt. There is a circulation space between the fixed shell and the connecting frame, so that wind or heat can flow through the circulation space, so that the lifting and lowering movement of the fixed shell and the connecting frame will not easily affect the drying of the transformer winding, thereby ensuring that the wind flows to different positions to drive the heat to flow.

[0019] 5. The transformer winding drying constant voltage equipment supports the side support plate inside the fixed shell through the support block, thereby increasing the bearing capacity of the fixed shell connecting the connecting frame, preventing the fixed shell and the connecting frame from being separated and affecting the use, ensuring that the activity space inside the fixed shell is not easily affected, and the fixing rod supports the contact plate on the side support plate, so that the contact plate can position the contact plate, which is convenient for the contact plate to connect the fixed shell and the fixing rod to cooperate, and preventing the side support plate from falling off at the connection position with the fixed shell to affect the bearing capacity of the fixed shell.

[0020] 6. The transformer winding drying constant pressure equipment is installed horizontally on the base through the bearing tray, which prevents the bearing tray from loosening or tilting when subjected to the pressure of the transformer winding, and ensures that the bearing tray is evenly subjected to the pressure of the transformer winding. After the pressure plate is placed on the transformer winding, it is pushed and can move along the guide frame, so that the pressure plate moves to adjust the position of the placed transformer winding, ensuring that the transformer winding placed on the pressure plate corresponds to the pressing plate.

[0021] 7. The transformer winding drying constant pressure equipment ensures the heating effect between the bearing tray and the pressure plate by making the installation position of the heat-conducting sleeve correspond to the flow slot on the bearing tray, so that the heat-conducting sleeve and the bearing tray cooperate with each other to circulate heat. There are balls inside the guide frame, so that the pressure plate drives the balls to rotate when it moves on the guide frame, so that the balls can reduce the friction force of the pressure plate when it rotates inside the guide frame, and prevent the pressure plate from tilting due to long-term movement.

[0022] 8. The transformer winding drying constant pressure equipment supports the mounting sleeve inside the sealing box through the protective plate to prevent the mounting sleeve from tilting and affecting the lifting and lowering of the adjusting rod, and the installation positions of the protective plate and the mounting sleeve can limit the rising distance of the connecting frame. The protective block supports the limiting plate on the mounting sleeve, so that the limiting plate can block the inside of the mounting sleeve, and the limiting plate protects the clamping plate above the mounting sleeve, thereby preventing the clamping plate from being easily damaged inside the mounting sleeve and slipping.

[0023] 9. The transformer winding drying constant pressure equipment is installed vertically on the limiting plate through the protective sleeve, which is convenient for the adjusting rod to pass through the protective sleeve for lifting and lowering, ensuring that the protective sleeve separates the adjusting rod and the clamping plate. The drying ring at the bottom of the limiting plate can limit the installation position of the protective sleeve, so that the heat generated by the drying ring is discharged downward from the inside of the installation sleeve, and the heat discharged by the installation sleeve flows from top to bottom to dry the transformer winding, thereby accelerating the flow of heat to the transformer winding position.

[0024] 10. The transformer winding drying constant pressure equipment is provided with multiple connection blocks on the limiting plate, so that the auxiliary support plate and the protective plate can tighten the sealing box from different positions, and the movable space between the limiting plate and the sealing box can be maintained. The assembly plates are distributed on the limiting plate in a circular shape, so that the assembly plates can be installed around the protective sleeve. The assembly plates are connected to the sealing box and cooperate with the auxiliary support plates, thereby increasing the bearing capacity of the protective sleeve installation position of the limiting plate and preventing the position where the adjustment rod and the sealing box are connected from being sunken.

The number of transformer windings placed can be adjusted according to the volume of the transformer windings on the supporting assembly 3, and the position of the transformer windings placed by the supporting assembly 3 can be rotated, so that the transformer windings can be rotated on the supporting assembly 3 to a position corresponding to the pressing assembly 6, ensuring that the pressing assembly 6 fully contacts the transformer windings when descending, so that the pressing assembly 6 is not prone to displacement when tightening the transformer windings, thereby ensuring the stability of the transformer windings when drying; The screw 8 is fixedly connected to the position of the base 1 away from the support rod 2. The screw 8 is driven by the motor to rotate clockwise on the base 1, so that the screw 8 drives the sealing box 4 to descend. When the sealing box 4 descends to contact the base 1, the sealing box 4 and the base 1 seal and dry the position where the transformer winding is placed. The screw 8 rotates counterclockwise to drive the sealing box 4 to rise, so that the rotation of the screw 8 can adjust the height of the sealing box 4, avoiding the sealing box 4 from affecting the placement of the transformer winding. The outer surface of the screw 8 is rotatably connected to The sealed box 4 is connected to an air supply box 5 on its outer surface. The air supply box 5 moves with the sealed box 4, so that the wind generated by the air supply box 5 can circulate inside the sealed box 4 and the base 1, so that the wind generated by the air supply box 5 drives the heat circulation, so that the air supply box 5 can play an auxiliary effect on the drying of the transformer winding, thereby improving the drying quality of the transformer winding. The air supply box 5 conveys wind when the sealed box 4 is separated from the base 1, thereby accelerating the air circulation at the transformer winding position, so that the wind generated by the air supply box 5 dissipates heat for the dried transformer winding; The protective component 7 is fixedly connected to the top of the inner cavity of the sealing box 4. The protective component 7 is used to dry the transformer winding from above. The protective component 7 can generate heat inside the sealing box 4, so that the heat generated by the protective component 7 circulates from top to bottom to dry the transformer winding, so that the protective component 7 cooperates with the dryer 9 to circulate heat from different positions to fully dry the transformer winding. The protective component 7 is connected to the sealing box 4, so that the protective component 7 reinforces the sealing box 4, thereby ensuring the activity space inside the sealing box 4, preventing the activity space inside the sealing box 4 from changing and affecting the seal during drying. The sealing box 4 is slidably connected with a clamping component 6 near the protective component 7. The height of the clamping component 6 can be adjusted on the sealing box 4, so that the clamping component 6 can adjust the transformer windings of different volumes for clamping when it moves, so that the clamping component 6 can apply uniform pressure when it contacts the transformer winding, avoiding damage to the position where the transformer winding contacts the clamping component 6, and ensuring the firmness of the clamping position of the transformer winding during the drying process; The pressing assembly 6 includes a connecting frame 62, which is slidably connected to the inner surface of the sealing box 4. When the connecting frame 62 is lifted or lowered, it moves along the inner wall of the sealing box 4, so that the connecting frame 62 drives the fixed shell 63 to move smoothly when lifting or lowering, and prevents the connecting frame 62 from tilting during the movement inside the sealing box 4, ensuring the pressing effect of the pressing plate 64 on the fixed shell 63 on the transformer winding, and the position where the connecting frame 62 contacts the sealing box 4 can be supported during the lifting process, thereby increasing the bearing capacity of the sealing box 4 itself, so that the connecting frame 62 and the fixed shell 63 cooperate with each other to protect themselves, and the top of the connecting frame 62 rotates An adjusting rod 61 is connected, and the adjusting rod 61 is subjected to a thrust to rotate clockwise on the sealed box 4, so that the adjusting rod 61 drives the connecting frame 62 to descend, and vice versa, the adjusting rod 61 rotates counterclockwise to drive the connecting frame 62 to rise inside the sealed box 4, so that the adjusting rod 61 is raised and lowered on the sealed box 4 to adjust the force of pressing the transformer winding, ensure the stability of the transformer winding on the supporting assembly 3, and facilitate the adjustment of the adjusting rod 61 to rotate to adjust the activity space inside the sealed box 4, so as to prevent the elongated distance of the adjusting rod 61 inside the sealed box 4 from affecting the placement of the transformer winding. The outer surface of the adjusting rod 61 is rotatably connected to the sealed box 4; A fixed shell 63 is fixedly connected to the bottom of the connecting frame 62. A temperature sensor 66 is fixedly connected to the bottom of the fixed shell 63. The temperature sensor 66 is lifted and lowered along with the fixed shell 63, so that the temperature sensor 66 can detect the temperature of the transformer winding in real time during drying, which is convenient for the staff to record the drying data and prevent the sealing box 4 from changing too much when it contacts the base 1. It is convenient for the staff to find problems when the transformer winding is dried. A clamping plate 64 is fixedly connected to the fixed shell 63 near the temperature sensor 66. Four clamping plates 64 are arranged on the fixed shell 63. When the clamping plates 64 are lifted and lowered, they correspond to the placement position of the transformer winding on the supporting assembly 3, so that the transformer winding is clamped during the descending process of the clamping plate 64. The clamping plate 64 protects the transformer winding when clamping the transformer winding to prevent the transformer winding from shifting on the supporting assembly 3 and falling off. Then, the clamping plate 64 is used to The lifting and pressing block 65 is reset as the pressing plate 64 rises, so that the lifting and pressing block 65 and the pressing plate 64 cooperate to increase the contact area during pressing.

The support block 611 cooperates with the side support plate 69 to limit the installation position of the inner partition plate 68, so that the side support plate 69 and the inner partition plate 68 can reinforce different positions, ensuring that the activity space inside the fixed shell 63 is not easily affected. The top of the support block 611 is fixedly connected to the side support plate 69, and the bottom of the side support plate 69 is fixedly connected to the fixing rod 610. 610 supports the contact plate 612 on the side support plate 69, so that the contact plate 612 can position the contact plate 612, which is convenient for the contact plate 612 to connect the fixed shell 63 and cooperate with the fixed rod 610, so that the fixed rod 610 can tighten the side support plate 69 on the contact plate 612, so that the fixed rod 610 and the support block 611 support the side support plate 69 from different positions, and prevent the connection position between the side support plate 69 and the fixed shell 63 from falling off and affecting the bearing capacity of the fixed shell 63. When the fixed rod 610 is subjected to pressure, it can be transmitted to the fixed shell 63 through the contact plate 612, avoiding the fixing rod 610 from breaking or bending, thereby ensuring the integrity of the fixing rod 610 when in use. The bottom end of the fixing rod 610 is fixedly connected with the contact plate 612.

[0034] The supporting assembly 3 includes a supporting tray 31, which is fixedly connected to the inner surface of the base 1. The supporting tray 31 is used to support the placed transformer winding. The supporting tray 31 is horizontally installed on the base 1, so that the supporting tray 31 supports the placement of the transformer winding, and prevents the supporting tray 31 from being easily loosened or tilted when subjected to the pressure of the placed transformer winding, ensuring that the supporting tray 31 is evenly subjected to the pressure of the placed transformer winding, and the supporting tray 31 is located above the dryer 9, so that the supporting tray 31 can block the heat generated by the dryer 9, and the circulation grooves opened in the supporting tray 31 circulate heat, so that the supporting tray 31 guides the heat to dry the bottom of the transformer winding, thereby increasing the drying area of ​​the transformer winding, and avoiding incomplete drying of the transformer winding due to uneven contact when the transformer winding is dried. The bottom of the inner cavity of the supporting tray 31 is fixedly connected to a guide frame 36, and the guide frame 36 has a ball inside, so that the pressure plate 32 is guided in the guide frame The guide frame 36 is provided with a plurality of support members 36a and 36b, and the support members 36b are provided with a plurality of support members 36a and 36b, and the support members 36b are provided with a plurality of support members 36b. The heat-conducting sleeve 33 is fixedly connected to the bottom of the tray 31. The heat-conducting sleeve 33 is used to guide the heat generated by the dryer 9 to the tray 31. The installation position of the heat-conducting sleeve 33 corresponds to the flow groove on the tray 31, so that the heat-conducting sleeve 33 can guide the heat generated by the dryer 9 to flow into the tray 31, thereby ensuring the heating effect between the tray 31 and the pressure plate 32. The heat-conducting sleeve 33 on the tray 31 can increase the contact area of ​​the tray 31, so that the heat-conducting sleeve 33 and the tray 31 cooperate with each other to circulate heat. The bottom of the inner cavity of the heat-conducting sleeve 33 is fixedly connected with a middle fixing rod 34, which is vertically installed in the heat-conducting sleeve 33 through the middle fixing rod 34 , so that the expansion plate 35 on the middle solid rod 34 is accurately expanded by the heat. As the expansion plate 35 expands to contact the inner wall of the heat-conducting sleeve 33, the expansion plate 35 can knock the heat-conducting sleeve 33, so that the heat-conducting sleeve 33 is knocked to drop the adhered dust, thereby ensuring the heat guiding effect of the heat-conducting sleeve 33. After the expansion plates 35 on the middle solid rod 34 are expanded, they can limit the flow of heat, so that the heat flows through the space between the two expansion plates 35. When the internal temperature of the heat-conducting sleeve 33 drops, the expansion plate 35 loses heat and shrinks, so that the expansion plate 35 is separated from the heat-conducting sleeve 33 on the middle solid rod 34, and the outer surface of the middle solid rod 34 is fixedly connected with the expansion plate 35.

The mounting sleeve 72 cooperates with multiple protective plates 71 to support the sealed box 4, and prevents the position where the sealed box 4 is connected to the protective plate 71 from falling off, causing the protective plate 71 and the mounting sleeve 72 to slide down. The installation position of the protective plate 71 and the mounting sleeve 72 can limit the rising distance of the connecting frame 62, so that the connecting frame 62 and the mounting sleeve 72 can reinforce each other when they are in contact. The bottom of the protective plate 71 is fixedly connected to the mounting sleeve 72, and the mounting sleeve 72 is fixedly connected to a protective block 75 near the protective plate 71. The protective block 75 supports the limiting plate 76 on the mounting sleeve 72, so that the limiting plate 76 can block the inside of the mounting sleeve 72, so that the limiting plate 76 protects the clamping plate 73 above the mounting sleeve 72, thereby preventing the clamping plate 73 from being easily damaged and slipping inside the mounting sleeve 72. The protective block 75 can support different positions of the limiting plate, thereby ensuring the stability of the limiting plate installation position, facilitating the limiting plate 76 and the protective plate 71 to cooperate with each other to protect the mounting sleeve 72, and the top of the protective block 75 is fixedly connected to the limiting plate 76; The clamping plate 73 is fixedly connected to the inner surface of the mounting sleeve 72. The movable space inside the mounting sleeve 72 can be divided by the clamping plate 73, so that the clamping plate 73 can guide the flow of heat inside the mounting sleeve 72, which is convenient for the heat to flow downward through the cooperation of the clamping plate 73 and the mounting sleeve 72. The positioner 74 on the clamping plate 73 can limit the lifting and lowering distance of the connecting frame 62, so that the positioning of the two positioners 74 keeps the connecting frame 62 stable during the lifting process, which is convenient for timely observation when the connecting frame 62 is tilted, thereby ensuring the accuracy of the connecting frame 62 during lifting and lowering. The bottom of the clamping plate 73 is fixedly connected with the positioner 74.

[0037] The bottom of the protection block 75 passes through the installation sleeve 72 , and the top of the positioner 74 passes through the clamping plate 73 and extends to the outside of the clamping plate 73 .

[0038] The inner surface of the limiting plate 76 is fixedly connected with a protective sleeve 710, which is vertically installed on the limiting plate 76 through the protective sleeve 710, so that the protective sleeve 710 protects the installation position of the adjusting rod 61, and facilitates the adjusting rod 61 to pass through the protective sleeve 710 for lifting and lowering movement, so that the protective sleeve 710 and the limiting plate 76 cooperate to limit the installation position of the adjusting rod 61, and the protective sleeve 710 cooperates with the clamping plate 73 inside the mounting sleeve 72, so that heat can flow through the activity space generated by the protective sleeve 710 and the clamping plate 73, ensuring that the protective sleeve 710 separates the adjusting rod 61 from the clamping plate 73. The lifting and lowering of the adjusting rod 61 is not likely to affect the clamping plate 73. The bottom of the limiting plate 76 is fixedly connected with a drying ring 711. The drying ring 711 can limit the installation position of the protective sleeve 710 at the bottom of the limiting plate 76, so that the heat generated by the drying ring 711 is discharged downward from the inside of the installation sleeve 72, and the heat discharged from the installation sleeve 72 flows from top to bottom to dry the transformer winding. The heat discharged by the drying ring 711 is blown by the wind delivered by the air supply box 5 during circulation, thereby accelerating the circulation of heat to the transformer winding position, so that the drying ring 711 and the dryer 9 cooperate with each other to dry the transformer winding. The assembly plate 77 is fixedly connected to the top of the limiting plate 76, and the sealing box 4 is connected to the auxiliary support plate 79 through the assembly plate 77, thereby increasing the bearing capacity of the position where the limiting plate 76 is installed with the protective sleeve 710, so that the assembly plate 77 can reinforce the position where the sealing box 4 is connected to the adjusting rod 61, and prevent the position where the adjusting rod 61 is connected to the sealing box 4 from being sunken. The assembly plate 77 and the auxiliary support plate 79 are connected to the sealing box 4 to maintain the level of the limiting plate 76, ensuring that the heat generated by the drying ring 711 on the limiting plate 76 flows downward. The top of the assembly plate 77 is fixedly connected to the sealing box 4, and the position of the limiting plate 76 away from the assembly plate 77 is fixedly connected with a connecting block 78 The locking cam 76 is secured to the locking cam 76 by the spring 76a and 76b, respectively, and the locking cam 76a is secured to the locking cam 76b with the spring 76b securing the locking cam 76a.

[0039] Example 2, please refer to Figure 1-Figure 12 , based on Example 1, the present invention provides a technical solution: a method for using a transformer winding drying constant pressure device, step 1: drive the screw 8 to rotate clockwise through a motor, so that the screw 8 rotates clockwise on the base 1 to drive the sealing box 4 to rise, and the sealing box 4 moves along the support rod 2 when rising, and stops when the sealing box 4 and the base 1 have sufficient placement space, and the transformer winding is placed on the pressure plate 32, and the placement position of the transformer winding corresponds to the clamping plate 64, and after the transformer winding is placed, a thrust is applied to the pressure plate 32 to rotate the pressure plate 32 on the guide frame 36, so as to adjust the placed transformer winding; Step 2: Use the supporting tray 31 to support the pressure plate 32 on the base 1. After the transformer winding is placed, the screw 8 rotates counterclockwise on the base 1 to drive the sealing box 4 to descend. When the sealing box 4 descends to contact the base 1, it stops. The adjusting rod 61 is rotated clockwise to make the adjusting rod 61 drive the connecting frame 62 to descend on the sealing box 4. When the connecting frame 62 slides along the inner wall of the sealing box 4, it drives the fixed shell 63 to descend. When the pressing plate 64 descends to contact the transformer winding, it squeezes. When adjusting the pressing plate 64 to descend, observe the pressing plate 64 squeezing the transformer winding from the observation window of the sealing box 4. When the pressing plate 64 contacts the transformer winding, the lifting and lowering pressure block 65 is pushed up by the transformer winding, thereby adjusting the position of the lifting and lowering pressure block 65. Step 3: After the transformer winding is fixed, the dryer 9 generates heat inside the base 1, so that the dryer 9 circulates heat from the bottom of the tray 31 to dry the transformer winding. The heat-conducting sleeve 33 guides the heat inside the tray 31, so that the expansion plate 35 is hit by the heat on the middle fixing rod 34. As the expansion plate 35 expands, the activity space inside the heat-conducting sleeve 33 is separated, so that the heat is transferred to the inside of the tray 31 along the heat conduction between the two expansion plates 35, thereby drying the bottom of the transformer winding. The air supply box 5 generates wind on the sealing box 4, so that the wind circulates inside the sealing box 4 to drive the heat to move and dry the transformer winding. Step 4: Use the assembly plate 77 to connect the sealing box 4 to fix the limiting plate 76, and the auxiliary support plate 79 is connected to the sealing box 4 on the connecting block 78. The connecting block 78 supports the limiting plate 76, so as to keep the installation position of the limiting plate 76 in a horizontal state, so that the protective sleeve 710 on the limiting plate 76 protects the rotation of the adjusting rod 61, and as the drying ring 711 on the limiting plate 76 works to generate heat, the wind force delivered by the air supply box 5 drives the heat to flow to the transformer winding, so that the heat generated by the drying ring 711 dries the transformer winding above, and the heat generated by the drying ring 711 flows through the fixed shell 63 and the connecting frame 62; Step 5: Use the protective plate 71 to fix the installation sleeve 72 on the sealing box 4, so that the protective block 75 on the installation sleeve 72 supports the limiting plate 76, and the clamping plate 73 inside the installation sleeve 72 cooperates with the protective sleeve 710 to guide the flow of heat. The positioner 74 positions the descending distance of the connecting frame 62 on the clamping plate 73. When the fixed shell 63 moves, the reinforcement column 67 and the inner partition plate 68 support it so that it maintains the movable space inside the fixed shell 63, and the support block 611 cooperates with the side support plate 69 to provide auxiliary support for the fixed shell 63. The fixing rod 610 limits the position of the contact plate 612 contacting the fixed shell 63 on the side support plate 69; Step six: After the transformer winding is dried, the adjusting rod 61 rotates counterclockwise, so that the adjusting rod 61 drives the connecting frame 62 to rise along the inner wall of the sealing box 4, and the fixed shell 63 rises with the connecting frame 62 to drive the clamping plate 64 to loosen the pressure on the transformer winding, and the lifting and lowering pressure block 65 loses pressure and descends. The screw 8 rotates clockwise again to drive the sealing box 4 to rise, and the air supply box 5, the drying ring 711 and the dryer 9 stop working. As the transformer winding is exposed, it is removed from the pressure plate 32.
