Description

Technical Field

[0001] The present invention relates to the technical field of transposed conductor detection, and particularly to a transposed conductor jumper detection device. Background Art

[0002] The windings of large power transformers use transposed conductors, which can significantly reduce load losses, reduce the temperature rise of the winding hot spots, improve the mechanical strength of the winding, make the structure more compact, and simplify the coil processing. Therefore, since the transposed conductors came out, they have been widely used in the design and manufacture of large power transformer windings. During the production process of transposed conductors, when the enameled rectangular copper wire is transposed and deformed, jumpers may occur. The specific manifestations of the enameled rectangular copper wire jumpers are the following two situations: 1. The wire pops out from the transposition and stacks on top of two columns of enameled rectangular copper wires, or when making the transposition, two enameled rectangular copper wires are made at one time or one enameled rectangular copper wire is missed. In this case, the thickness dimension of the transposed conductor exceeds the normal dimension range; 2. When the enameled rectangular copper wire is transposed and deformed, the enameled rectangular copper wire is knocked over, causing the enameled rectangular copper wire to be clamped between two columns of wires or jump out of the two columns of wires. In this case, the width dimension of the transposed conductor exceeds the normal dimension range. Since the transposed conductors with jumpers are not easily detected during the production process, serious quality accidents are likely to occur. The following problems exist in the prior art:

[0003] Existing transposed conductor mechanisms generally can only detect jumpers of transposed conductors with a single size, and it is not convenient to adjust according to the size of the transposed conductor, thus affecting the versatility of the detection device. Moreover, when clamping and positioning the transposed conductor, there is a lack of fixation of the transposed conductor, which further affects the detection of the wire mechanism. Secondly, the same guide rollers cannot be adjusted either, and cannot position and guide transposed conductors of other sizes, affecting the accuracy of the detection. Summary of the Invention

[0004] The present invention provides a transposed conductor jumper detection device to solve the problems existing in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is:

One end of the positioning plate is fixedly connected to one end of the limiting plate. The outer wall of the screw rod and the inside of the positioning groove are arranged on the same vertical line. The outer wall of the rubber pressing block is engaged with the inside of the positioning groove.

[0010] A further improvement of the technical solution of the present invention lies in that: the detection component includes a detection rod, two fixing blocks, a mounting block, a pressing block and two bearings.

Then, by controlling the guiding and positioning mechanism 7, the transposed conductor can be positioned and guided for adjustment to ensure that the transposed conductor is in a horizontal and straight state and contacts the lower surface of the detection rod 61.

[0029] Embodiment 2

[0030] As Figures 1-6As shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, an installation groove 201 is provided inside the fixed shell 2, and moving grooves 202 communicating with the installation groove 201 are respectively provided on the left and right sides of the top of the fixed shell 2. A positioning groove 203 is provided on one side of the top of the fixed shell 2 close to the moving groove 202. The clamping and fixing mechanism 3 includes two tension wheels 31, two connecting plates 32, a sliding rod 33, a return spring 34, two connecting blocks 35, two convex plates 36, two limiting plates 37 and two positioning components 38. The outer parts of the two connecting plates 32 are respectively arranged at equal intervals inside the two moving grooves 202. The bottoms of the two tension wheels 31 are respectively rotatably connected to the tops of the two connecting plates 32. One ends of the two connecting blocks 35 are respectively fixedly connected to the tops of the opposite ends of the connecting plates 32. The end of the connecting block 35 away from the connecting plate 32 is fixedly connected to the upper side of one end of the convex plate 36. The left and right ends of the sliding rod 33 are respectively fixedly connected to the inner wall of the installation groove 201. The outer wall of the sliding rod 33 passes through the left and right ends of the two connecting plates 32 and the convex plate 36 and is slidably connected therebetween. The return spring 34 is sleeved on the outer wall of the sliding rod 33. The left and right ends of the return spring 34 are respectively fixedly connected to the opposite surfaces of the two connecting plates 32. By pulling the two tension wheels 31 outwards to open, the return spring 34 is stretched and deformed, and the two tension wheels 31 are driven by the reaction force of the return spring 34 to clamp the outside of the transposed conductor. The top of the outer wall of the convex plate 36 passes through the top of the fixed shell 2 through the moving groove 202.

The positioning component 38 includes a positioning plate 381, a screw 382, a knob 383 and a rubber pressing block 384. The outer wall of the screw 382 passes through the upper and lower ends of the middle part of the positioning plate 381 and is threadedly connected therebetween. The bottom of the knob 383 is fixedly connected to the top of the screw 382. The bottom of the screw 382 is fixedly connected to the upper surface of the rubber pressing block 384.

The outer wall of the screw 382 and the inside of the positioning groove 203 are arranged on the same vertical line. The outer wall of the rubber pressing block 384 is engaged with the inside of the positioning groove 203. By rotating the screw 382, the rubber pressing block 384 is driven to be squeezed and engaged into the positioning groove 203 to position the tension wheel 31 and prevent displacement, further improving the stability of the clamping of the transposed conductor.

[0031] Embodiment 3

[0032] As Figures 1-6As shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, the detection component 6 includes a detection rod 61, two fixed blocks 62, a mounting block 63, a pressing block 64, and two bearings 65. One ends of the two fixed blocks 62 are respectively fixedly connected to the left and right ends of the detection rod 61. One end of the mounting block 63 is fixedly connected to one side of the right fixed block 62. One ends of the two bearings 65 are respectively rotatably connected to the front and rear ends of the mounting block 63. One end of the pressing block 64 is fixedly connected to one end of the left fixed block 62. A switch 81 is arranged on the top of the pressure sensor 8. The output end of the second electric telescopic rod 5 is fixedly connected with a U-shaped clamping plate 51. The outer wall of the mounting block 63 is arranged inside the U-shaped clamping plate 51. The other ends of the two bearings 65 are respectively fixedly connected to the inner wall of the U-shaped clamping plate 51. The lower surface of the pressing block 64 is lapped on the top of the pressure sensor 8. The detection rod 61 is installed in the U-shaped clamping plate 51 through the mounting block 63. The pressing block 64 presses the switch 81 on the pressure sensor 8. When the transposition conductor is broken, the transposition conductor drives the detection rod 61 to push upward by inertia, so that the pressing block 64 and the switch 81 are disengaged.

[0033] Embodiment 4

[0034] As Figures 1-6 shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, the guiding and positioning mechanism 7 includes a housing 71, a stepping motor 72, a lead screw 73, a guiding roller 74, two mounting discs 75, a moving block 76, and a limiting rod 77. The outside of the stepping motor 72 is fixedly connected to the top of the housing 71. The output shaft of the stepping motor 72 penetrates into the interior of the housing 71 and is fixedly connected to the top of the lead screw 73. The bottom of the lead screw 73 is rotatably connected to the bottom of the inner wall of the housing 71. The opposite surfaces of the two mounting discs 75 are respectively rotatably connected to the left and right ends of the guiding roller 74. The outer wall of the lead screw 73 penetrates through the upper and lower ends of the moving block 76 and is threadedly connected therebetween. The stepping motor 72 drives the lead screw 73 to rotate, so as to drive the guiding roller 74 to move up and down, position and guide the bottom of the transposition conductor, and ensure that the transposition conductor maintains a horizontal straight state. The right end of the outer wall of the moving block 76 penetrates through the outside of the housing 71 and is fixedly connected to the outer wall of the mounting disc 75. The outer wall of the limiting rod 77 penetrates through the upper and lower ends of the moving block 76 close to one side of the housing 71 and is slidably connected therebetween. The bottoms of the housing 71 and the limiting rod 77 are both fixedly connected to the top of the detection table 1. When the lead screw 73 rotates, it drives the moving block 76 to move horizontally along the limiting rod 77, so as to limit the moving track of the guiding roller 74.

[0035] Next, the working principle of the transposition conductor jumper detection device will be specifically described.

[0036] As Figures 1-6As shown in the figure, first, when using this device to detect the jumper wire of the transposed conductor, first, connect the control panel 10 to an external power supply through a wire to provide power control for the first electric telescopic rod 4, the second electric telescopic rod 5, the stepping motor 72, the pressure sensor 8, and the alarm 9. First, place the two ends of the transposed conductor between the two tension wheels 31 on the front and rear fixed shells 2 in sequence. By driving the two tension wheels 31 to pull outwards along the moving groove 202 through the convex plate 36 of the two side limiting plates 37, the reset spring 34 is driven to stretch, so that the reset spring 34 deforms under force and exerts a reaction force on the connecting plate 32, so that the two tension wheels 31 clamp the outside of the transposed conductor. Then, according to the position where the positioning component 38 moves, by rotating the knob 383 downward, the screw rod 382 drives the rubber pressing block 384 to squeeze and fit into the positioning groove 203 for positioning, preventing the tension wheel 31 from displacing again, and increasing the stability of clamping the transposed conductor. Subsequently, operate the control panel 10 to start the two stepping motors 72. The output shafts of the stepping motors 72 drive the lead screws 73 to rotate, so that the guide rollers 74 are driven to move to the lower surface of the transposed conductor and position and guide it, ensuring that the transposed conductor is in a horizontal straight state. Then, operate the first electric telescopic rod 4 and the second electric telescopic rod 5 to start in sequence, and move the lower surface of the detection rod 61 to contact the upper surface of the transposed conductor. At the same time, ensure that the pressing block 64 presses the switch 81 on the pressure sensor 8. When a jumper occurs in the transposed conductor, the generated inertia pushes the detection rod 61 upward, so that the detection rod 61 tilts upward along the U-shaped clamping plate 51 through the mounting block 63, so that the pressing block 64 is separated from the switch 81, so that the connection between the pressure sensor 8 and the alarm 9 is disconnected, and the alarm 9 receives the signal and issues an alarm.

[0037] The specific types and structures of the used electric telescopic rods, stepping motors, pressure sensors, and alarms are all existing products, and the specific circuit connection structure and control relationship between the control panel and the electric telescopic rods, stepping motors, pressure sensors, and alarms are all prior arts, and will not be elaborated here too much.

[0038] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
