Description

Technical Field

[0001] The present application relates to the technical field of insulating paper, and particularly relates to an insulating paper for the inner skeleton of an amorphous transformer coil and a processing device therefor. Background Art

[0002] An amorphous transformer is a low-loss and high-efficiency power transformer. Such a transformer uses an iron-based amorphous metal as the iron core. The inner skeleton of the amorphous transformer coil serves as a support structure for the amorphous transformer coil. In order to achieve the insulation effect of the inner and outer sides of the inner skeleton of the amorphous transformer coil, insulating paper is usually provided on both the inner and outer sides of the inner skeleton of the amorphous transformer coil.

[0003] When the existing insulating paper is used, it needs to be connected to the coil skeleton. However, the existing insulating paper itself does not have adhesiveness. When connecting, it is necessary to use iron wires or other connecting pieces to reduce the gap between it and the coil skeleton during connection. However, when the insulating paper is initially connected to the coil skeleton, during the process of using additional connecting pieces to fix it, since the insulating paper has no adhesiveness, the operator needs to keep holding it in the position where it needs to be installed by hand, and it is necessary to keep the insulating paper in a state of winding around the coil skeleton, which is rather troublesome when connecting it to the coil skeleton.

[0004] Therefore, the present invention proposes an insulating paper for the inner skeleton of an amorphous transformer coil and a processing device therefor to improve this problem. Summary of the Invention

Detailed implementation manners

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0042] like Figure 1 - Figure 2 As shown, in some embodiments of the present application, an insulating paper for an inner frame of an amorphous transformer coil is provided, comprising:

[0043] An upper paper base 1 is provided with a semi-groove 101, which is arranged in a linear array on the upper paper base 1 along the width direction of the upper paper base 1, and is pressed on the upper paper base 1 by pressing during processing, so that an indentation is formed on the upper paper base 1, and the indentation is the semi-groove 101;

[0044] The lower paper base 2 also has a semi-groove 101 formed thereon. The manufacturing method of the semi-groove 101 on the lower paper base 2 is consistent with the above method. A plurality of inner ribs 3 are installed in the semi-groove 101. The inner ribs 3 are made of plastic material. Since the upper paper base 1 and the lower paper base 2 are insulating paper, the inner ribs 3 are wrapped by the two so that the inner ribs 3 are not in contact with the outside world. Therefore, the inner ribs 3 can be made of copper or other plastic materials. When the insulating paper is wound onto the coil skeleton of the amorphous transformer, the upper paper base 1 and the lower paper base 2 are supported by the inner ribs 3, so that the insulating paper can be stably wound on the coil skeleton when initially connected, and the operator does not need to support it all the time, which increases the convenience of the insulating paper during installation;

[0045] A plurality of notches 301 are provided on the inner rib 3, and the notches 301 are arranged in a linear array on the inner rib 3 along the length direction of the inner rib 3. The lower paper base 2 and the upper paper base 1 are connected by bonding. An inner cavity 302 is provided on the inner rib 3, and the thickness of the inner rib 3 is thinned by the inner cavity 302. The inner rib 3 can be better cut off by the notches 301, so that the insulating paper can be taken out easily.

[0046] A break mark 6 is provided on the upper paper base 1 and the lower paper base 2. The break marks 6 are arranged in a linear array along the length direction of the upper paper base 1 or the lower paper base 2. The projection of the notch 301 on the upper paper base 1 or the lower paper base 2 coincides with the break mark 6. The distribution of the break mark 6 is consistent with the distribution of the notch 301. When the insulating paper needs to be taken, the insulating paper is cut along the position of the break mark 6 by a knife or tearing, which further facilitates the taking of the insulating paper and increases the practicality of the insulating paper.

[0047] Compared with the prior art, a semi-groove 101 is provided on the upper paper base 1 and the lower paper base 2, and the inner rib 3 is installed through the semi-groove 101. When cutting and taking the insulating paper, the thickness of the insulating paper is reduced to facilitate cutting through the cooperation of the break mark 6 and the notch 301. The inner rib 3 is made of plastic material. When the insulating paper is wound in use, the inner rib 3 can provide support for the upper paper base 1 and the lower paper base 2, so that when they are initially connected, even if the operator does not support the insulating paper, the insulating paper can be relatively stably attached to the coil skeleton, thereby increasing the convenience of connecting the insulating paper.

[0048] As Figure 2 shown, in some embodiments, a limiting rod 4 is installed on the inner rib 3, and auxiliary grooves 5 for accommodating the limiting rod 4 are provided on both the upper paper base 1 and the lower paper base 2. Two limiting rods 4 are installed on one inner rib 3. One of the limiting rods 4 increases the volume of the inner rib 3, thereby increasing the supporting effect of the inner rib 3 on the upper paper base 1 and the lower paper base 2. The manufacturing method of the auxiliary groove 5 is the same as that of the semi-groove 101;

[0049] A plurality of break openings 401 are provided on the limiting rod 4, and the intervals between the break openings 401 are the same as the intervals at which the notches 301 are distributed on the inner rib 3. During use, the thickness of the limiting rod 4 is reduced through the break openings 401, thereby reducing the influence of the limiting rod 4 on cutting the insulating paper;

[0050] When the limiting rod 4 is inserted into the auxiliary groove 5, the rotation of the inner rib 3 in the semi-groove 101 is restricted. During use, the limiting rod 4 forms a protrusion on the circumferential side of the inner rib 3, so that the inner rib 3 will not rotate by mistake during installation. When preparing the insulating paper, the notch 301 can be accurately aligned with the breaking mark 6, increasing the convenience during the preparation of the insulating paper.

[0051] As Figures 3 - 12 shown, the present application also provides insulating paper for the inner skeleton of an amorphous transformer coil. In some embodiments, it is used to prepare the above-mentioned insulating paper for the inner skeleton of an amorphous transformer coil, including:

[0052] A mounting frame 7, on which a longitudinal cutting member 8 is installed. The longitudinal cutting member 8 includes a rotating rod 801 rotatably installed on the mounting frame 7. Ring knives 802 are linearly arrayed on the rotating rod 801 along its axial direction. A driving motor 803 is installed on the mounting frame 7, and the output shaft of the driving motor 803 is connected to the rotating rod 801. The mounting frame 7 is used to carry the insulating paper. When the insulating paper passes through the position of the ring knives 802, the driving motor 803 drives the rotating rod 801 to drive the ring knives 802 to cut the insulating paper, and perform cutting indexing along the width of the insulating paper;

[0053] A transverse cutting member 9 is installed on the mounting frame 7. The transverse cutting member 9 includes a fixed frame 901 installed on the mounting frame 7. A transverse cutting knife 902 is slidably installed on the fixed frame 901. A driving part connected to the transverse cutting knife 902 is installed on the fixed frame 901. The driving part is used to drive the transverse cutting knife 902 to approach or move away from the mounting frame 7. The driving part drives the transverse cutting knife 902 to approach the mounting frame 7 to cut off the insulating paper, so that the insulating paper is cut off along the length direction;

[0054] The rewinding member 10 is installed on one side of the mounting frame 7. The rewinding member 10 includes a rewinding frame 1001. A rewinding roller 1002 is rotatably installed on the rewinding frame 1001. The rewinding roller 1002 is connected to the driving motor 803 through a first pulley assembly 1003, so that the longitudinal cutting member 8 and the rewinding member 10 are started or stopped simultaneously. The first pulley assembly 1003 includes two pulleys and a belt. One of them is connected to the rewinding roller 1002, and the other is connected to the output shaft of the driving motor 803. In use, when the driving motor 803 drives the rotating rod 801 to rotate, it also drives the rewinding roller 1002 to rotate through the first pulley assembly 1003. The rewinding roller 1002 is used for rewinding the insulating paper. Furthermore, the insulating paper is rewound and transported by the rewinding roller 1002, driving the insulating paper to move on the mounting frame 7;

[0055] When the device is in use, a plurality of paper cores of insulating paper are sleeved on the rewinding roller 1002. The rewinding roller 1002 drives the insulating paper to move on the mounting frame 7. The insulating paper is cut by the ring knife 802 and divided into multiple strips, so that the insulating paper can be wound around different paper cores. When a certain thickness of insulating paper is wound on the paper core, the insulating paper located on the mounting frame 7 is cut off by the transverse cutting knife 902 to complete the winding of the insulating paper, which is convenient for subsequent packaging and leaving the factory.

[0056] As Figure 5 shown, in some embodiments, the longitudinal cutting member 8 further includes a sliding groove 804 opened on the rotating rod 801. A slider 805 slidably engaged with the sliding groove 804 is installed on the ring knife 802. The slider 805 is slidably inserted into the sliding groove 804. In use, the ring knife 802 can slide on the rotating rod 801, and the width of the cut insulating paper can be adjusted during use;

[0057] A fixed rod 806 fixedly connected to the mounting frame 7 is rotatably installed on one of the ring knives 802. A sliding rod 807 slidably engaged with the mounting frame 7 is rotatably installed on the other ring knives 802. A circular ring rotatably engaged with the rotating rod 801 is installed on the ring knife 802. Annular plates rotatably engaged with the circular ring are installed at the ends of the fixed rod 806 and the sliding rod 807, so that the fixed rod 806 or the sliding rod 807 is rotatably connected to the ring knife 802, so that when the ring knife 802 rotates with the rotating rod 801, it will not drive the fixed rod 806 and the sliding rod 807 to rotate together with it;

[0058] A threaded rod 808 is rotatably mounted on the sliding rod 807 away from the fixed rod 806, and the threaded rod 808 is threadedly connected to the mounting frame 7. The fixed rod 806 and the sliding rod 807 are connected by a scissor-fork structure 809, so that when one of the sliding rods 807 slides, the other sliding rods 807 are driven to approach or move away from the fixed rod 806 through the scissor-fork structure 809. The scissor-fork structure 809 includes a plurality of mutually hinged rod bodies, the fixed rod 806 and the sliding rod 807 are hinged to the rod body, and the two ends of the rod body on the fixed rod 806 are respectively hinged to the rod end of the adjacent sliding rod 807, and its shape is as follows: Figure 9 As shown, the threaded rod 808 is rotatably matched with the sliding rod 807 which is the outermost, i.e., the farthest from the fixed rod 806;

[0059] When in use, by rotating the threaded rod 808 to push the sliding rod 807, the rod body of the scissor structure 809 on the sliding rod 807 pulls or pushes the adjacent rod body, and the scissor structure 809 pulls or pushes the sliding rod 807 closer to or away from the fixed rod 806, so that the sliding rod 807 drives the ring knife 802 to slide on the rotating rod 801, and then the spacing between the ring knives 802 is adjusted, and then the width of the cut insulating paper is adjusted, so that the device can cut insulating paper of different widths, thereby improving the specifications and types of insulating paper output.

[0060] like Figure 9 and Figure 10 As shown, in some embodiments, a first spool wheel 11 is mounted on the free end of the rotating rod 801, and a second spool wheel 12 is rotatably mounted on the mounting frame 7. The first spool wheel 11 and the second spool wheel 12 are connected by a friction belt 13. The first spool wheel 11, the second spool wheel 12 and the friction belt 13 form a pulley and a belt structure, so that when the rotating rod 801 rotates, the second spool wheel 12 can also be driven to rotate. A plate body is mounted on the mounting frame 7, and the plate body is annular. The second spool wheel 12 is rotatably matched with the annular plate.

[0061] Both the second spool 12 and the threaded rod 808 are provided with φ-shaped holes 1201. A φ-shaped rod 1202 is slidably inserted into the φ-shaped hole 1201 on the second spool 12. The φ-shaped rod 1202 is used to connect or disconnect the second spool 12 from the threaded rod 808. When the device cuts the insulating paper, the φ-shaped rod 1202 is only inserted into the φ-shaped hole 1201 on the second spool 12 and is not connected to the threaded rod 808. At this time, the rotation of the second spool 12 will not drive the threaded rod 808 to rotate. When the cutting of a batch of insulating paper is completed and it is necessary to cut the insulating paper of the next batch with different specifications, the φ-shaped rod 1202 is inserted into the φ-shaped hole 1201 on the threaded rod 808, so that the second spool 12 is connected to the threaded rod 808, enabling the second spool 12 to drive the threaded rod 808 to rotate. And because the φ-shaped rod 1202 is slidably inserted into the φ-shaped hole 1201, the threaded rod 808 can not only rotate but also change its position on the mounting bracket 7 through the sliding fit between the φ-shaped rod 1202 and the φ-shaped hole 1201, improving the feasibility of the device;

[0062] When the device is adjusted, by inserting the φ-shaped rod 1202, the distance between the ring cutters 802 can be adjusted by the rotating rod 801, facilitating the adjustment of the device for insulating paper of different specifications, increasing the practicability of the device and also increasing the convenience of adjusting the ring cutters 802.

[0063] As Figure 4 and Figure 6 shown, in some embodiments, the driving part includes a sub-motor 903 installed on the fixed frame 901. An eccentric wheel 904 is installed on the output shaft of the sub-motor 903. A pulley is installed on the sub-motor 903, and a pulley is also installed on the rotating shaft of the eccentric wheel 904. A belt is installed between the two pulleys, so that when the sub-motor 903 is started, the eccentric wheel 904 makes a circular motion around the output shaft of the rotating shaft of the eccentric wheel 904;

[0064] A movable rod 905 is slidably mounted on the fixed frame 901, one end of the movable rod 905 is connected to the cross-cutting knife 902, and a square frame plate 906 is mounted on the other end. The square frame plate 906 is used to accommodate the eccentric wheel 904. A frame plate 907 is slidably mounted on the movable rod 905, and extension plates 908 are mounted on both sides of the frame plate 907. A accommodating plate 909 that slidably cooperates with the extension plate 908 is mounted on the fixed frame 901. When the auxiliary motor 903 drives the eccentric wheel 904, the frame plate 906 is pushed on the inner wall of the frame plate 906 through the eccentric wheel 904, so that the movable rod 905 is driven on the fixed frame 901. The fixed frame 901 moves in the vertical and horizontal directions respectively. When it slides in the vertical direction, it slides with the frame plate 907. When the movable rod 905 slides in the horizontal direction, it pushes the frame plate 907 to slide on the accommodating plate 909 through the extension plate 908, so that the movable rod 905 drives the cross-cutting knife 902 to make a rectangular movement on the mounting frame 7, so that the cross-cutting knife 902 not only applies force in the vertical direction when contacting with the insulating paper, but also can drag in the horizontal direction, further increasing the cutting effect of the cross-cutting knife 902 on the insulating paper.

[0065] like Figure 6 and Figure 8 As shown, in some embodiments, a through slot 28 is provided on the side wall of the fixing frame 901, and a safety rod 14 is installed on the cross-cutting knife 902 to slide with the through slot 28, and the safety rod 14 can slide in the through slot 28 in the vertical direction and the horizontal direction;

[0066] An insertion rod 16 is slidably mounted on the fixing frame 901 through a connecting spring 15, and an insertion hole 17 for accommodating the insertion rod 16 is opened on the safety rod 14. When the insertion rod 16 is inserted into the insertion hole 17, the insertion rod 16 blocks the inner wall of the insertion hole 17, thereby limiting the movement of the safety rod 14 on the fixing frame 901;

[0067] A rotating column 18 is rotatably mounted on the fixed frame 901, and the free end of the winding roller 1002 is connected to the rotating column 18 through a second pulley assembly 1004. The second pulley assembly 1004 includes two pulleys and a belt, one of which is connected to the rotating column 18, and the other is connected to the free end of the winding roller 1002. The belt is used to connect the two pulleys, so that when the winding roller 1002 rotates, the rotating column 18 is driven to rotate;

[0068] A plurality of abutting blocks 19 are slidably mounted on the rotating column 18. The abutting blocks 19 are arranged in an annular array around the axis of the rotating column 18. When the rotating column 18 rotates, the abutting blocks 19 abut against the inserting rod 16 so that the inserting rod 16 is inserted into the inserting hole 17. When the rotating column 18 rotates, the abutting blocks 19 are swung by centrifugal force, causing the abutting blocks 19 to move away from the rotating column 18, thereby causing the abutting blocks 19 to abut against the inserting rod 16, and further causing the inserting rod 16 to be inserted into the inserting hole 17. When the winding roller 1002 rotates, the safety rod 14 and the auxiliary motor 903 cooperate to limit the movement of the cross-cutting knife 902, so that when the batch of insulating paper is not processed completely, the cross-cutting knife 902 will not cut the insulating paper. After the batch of insulating paper is processed completely, the winding roller 1002 stops rotating, causing the rotating column 18 to stop rotating, and the abutting blocks 19 to release the abutment against the inserting rod 16. The inserting rod 16 is pulled back by the connecting spring 15 to disconnect it from the inserting hole 17. At this time, the auxiliary motor 903 is started to drive the cross-cutting knife 902. During use, the stability of the cross-cutting knife 902 when not in use is increased.

[0069] As Figure 7 shown, in some embodiments, an inner groove 1005 is formed on the winding roller 1002. One side opening of the inner groove 1005 communicates with the outside. One side of the winding frame 1001 is slidably mounted with a side plate 35 through a rod. The side plate 35 is located on one side of the opening of the inner groove 1005. During use, by sliding the side plate 35 away from the winding frame 1001, one side of the winding roller 1002 is exposed, and the paper core of the insulating paper is sleeved on the winding roller 1002 from this side;

[0070] A lifting rod 1007 is slidably mounted on the winding roller 1002 through a return spring 1006. One end of the lifting rod 1007 is provided with an arc-shaped plate 1008, and the other end is located in the inner groove 1005. The return spring 1006 forces the lifting rod 1007 to approach the winding roller 1002, and the arc-shaped plate 1008 is used to abut against the inner wall of the paper core;

[0071] A driving rod 10010 is slidably installed in the inner groove 1005 by pushing the spring 1009, and a lifting block 10011 is installed on the driving rod 10010. A blocking cover 10012 is rotatably installed on the winding frame 1001, and the blocking cover 10012 is rotatably connected to the side plate 35. The blocking cover 10012 is threadedly connected to the inner groove 1005. The blocking cover 10012 is used to cover the opening of the inner groove 1005 and to resist the driving rod 10010, so that the lifting block 10011 resists the lifting rod 1007, and the pushing spring 1009 pushes the driving rod 10010 away from the inner groove 1005. When the blocking cover 10012 is threadedly connected to the winding roller 1002, the blocking cover 10012 resists the driving rod 10010. , so that the lifting block 10011 resists and pushes the lifting rod 1007, thereby causing the lifting rod 1007 to move outward, thereby causing the arc plate 1008 to resist the inner wall of the paper core, so that the paper core can be stably installed on the winding roller 1002. When the processed insulating paper needs to be removed, when the blocking cover 10012 is released from the threaded connection with the winding roller 1002, the pushing spring 1009 pushes the driving rod 10010 to move toward the opening of the inner groove 1005, so that the lifting block 10011 is away from the lifting rod 1007, so that the reset spring 1006 pulls the lifting rod 1007 close to the winding roller 1002, thereby causing the arc plate 1008 to release the resistance to the paper core, so that the processed insulating paper can be removed easily;

[0072] The blocking cover 10012 is not only used to cover the opening of the inner groove 1005 , but also can limit the tendency of the side plate 35 to move away from the winding frame 1001 , thereby improving the practicality of the blocking cover 10012 .

[0073] like Figure 11 As shown, in some embodiments, a sliding frame 20 is mounted on the mounting frame 7, a connecting plate 22 is slidably mounted on the sliding frame 20 via a tension spring 21, a guide rod 23 is mounted on the connecting plate 22 and slides through the side wall of the sliding frame 20, a slot is provided on the sliding frame 20, the slot penetrates the sliding frame 20, the guide rod 23 is slidably mounted in the sliding frame 20, and the tension spring 21 pulls the connecting plate 22 away from the mounting frame 7;

[0074] A hinged rod 24 is hinged on the guide rod 23, and a torsion spring 25 is installed between the hinged rod 24 and the guide rod 23. A pressure roller 26 is rotatably installed on the free end of the hinged rod 24. A spring telescopic rod 27 is installed on the side wall of the first I-shaped wheel 11. The spring telescopic rod 27 is used to contact or release the contact with the guide rod 23. The torsion spring 25 makes the hinged rod 24 in an inclined state on the guide rod 23 and faces away from the winding roller 1002. When in use, when the first I-shaped wheel 11 rotates with the rotating rod 801, the spring telescopic rod 27 is driven to gradually approach the guide rod 23 and press it, so that it drives the pressure roller 26 to approach the upper surface of the mounting frame 7 and contact the insulating paper. The winding roller 1002 and the pressure roller 26 generate forces in opposite directions on the insulating paper, thereby straightening the insulating paper, further facilitating the cutting of the insulating paper, and increasing the cutting effect of the device on the insulating paper;

[0075] During the pulling process of the insulating paper, the rotation of the pressing roller 26 reduces the possibility of the pressing roller 26 blocking the transportation of the insulating paper.

[0076] like Figure 12 As shown, in some embodiments, a 匚-shaped plate 29 is hinged on the mounting frame 7, a holding rod 31 is slidably installed on the 匚-shaped plate 29 through a holding spring 30, and a mounting rod 32 is slidably installed on the mounting frame 7 through an elastic member 34, the elastic member 34 is a spring, and a mounting hole 33 for accommodating the mounting rod 32 is opened on the free end of the 匚-shaped plate 29. When the mounting rod 32 is inserted into the mounting hole 33, the holding rod 31 is parallel to the upper surface of the mounting frame 7. When in use, when installing the insulating paper, the 匚-shaped plate 29 is rotated away from the mounting frame 7. After the insulating paper is laid, the 匚-shaped plate 29 is rotated. When the mounting hole 33 thereon is aligned with the mounting rod 32, the elastic member 34 pushes the mounting rod 32 to be inserted into the mounting hole 33, and the rotation of the 匚-shaped plate 29 is restricted. At this time, the holding spring 30 forces the holding rod 31 to hold the insulating paper, thereby increasing the tension of the insulating paper when it is transported, and further facilitating the cutting of the insulating paper.

[0077] When it is necessary to replace the next batch of insulating paper, press the installation rod 32 to release the connection with the installation hole 33. At this time, rotate the mold plate 29 to facilitate the installation of the next batch of insulating paper.
