Description

Technical Field

[0001] The present invention relates to the technical field of iron core discharge, and particularly to a transformer iron core discharge detection device. Background Art

[0002] The transformer iron core is the main magnetic circuit part in a transformer, usually stacked by hot-rolled or cold-rolled silicon steel sheets with a relatively high silicon content and an insulating paint coated on the surface. The iron core and the coil wound around it together form a complete electromagnetic induction system. The size of the power transmitted by the transformer depends on the material and cross-sectional area of the iron core. The main material of the transformer iron core is silicon steel sheet. Silicon steel is used as the iron core of the transformer because silicon steel itself is a magnetic material with a very strong magnetic conduction ability and can generate a large magnetic induction intensity in the energized coil.

[0003] The principle of transformer iron core discharge is based on electromagnetic induction and partial discharge phenomena. The main function of the transformer iron core is to conduct magnetism and form a magnetic circuit, enabling electrical energy to be converted through the magnetic field. During the process of discharging the transformer iron core, by detecting the current change in the iron core, it can be detected whether the iron core is damaged. Generally, the methods for detecting the transformer iron core are through large-scale detection equipment or manual detection. The structure of the large-scale detection equipment is complex and difficult to operate, and the accuracy of manual detection is not high. These two methods cannot meet the requirement of detecting the iron core of the transformer outdoors. Summary of the Invention

On one side of the horizontal frame, a second threaded rod is rotatably connected. One end of the second threaded rod is threadedly connected to a second threaded cylinder. The other end of the second threaded rod is fixedly connected to a motor. On one side of the horizontal frame, at the position between the second threaded cylinder and the horizontal frame, a slide rail is fixedly connected;

[0007] On one side of the second threaded cylinder, a detection mechanism is installed, and the detection mechanism is used to detect the discharge condition of the transformer core;

[0008] At the edge position of one side of the bottom plate, a lifting mechanism is installed, and the lifting mechanism is used to adjust the position of the transformer core.

One end of the first connecting bar is rotatably connected to one side of the horizontal frame. One side of the second threaded cylinder is slidably connected with the slide rail.

[0010] In a preferred solution, the detection mechanism includes a detection disc fixedly connected to one side of the second threaded cylinder. On one side of the detection disc, a rotating seat is rotatably connected. At the top of the rotating seat, a positioning bolt is threadedly connected. On one side of the rotating seat, a plurality of first detection frames are respectively rotatably connected. One end of the first detection frame is threadedly connected to a first bolt. The other end of the first detection frame is threadedly connected to a second bolt. Near the second bolt at the other end of the first detection frame, a second detection frame is rotatably connected.

[0011] One end of the second detection frame is threadedly connected to a third bolt. At the position of the third bolt at one end of the second detection frame, an elastic cylinder is rotatably connected. On one side of the first detection frame and the second detection frame, mounting plates are respectively fixedly connected. On one side of the mounting plate, two mounting frames are fixedly connected. On the bottom surface of the mounting frame, a plurality of detection holes are respectively arranged. Near the detection holes on the bottom surface of the mounting frame, a plurality of fixing holes are arranged.

[0012] The multiple detection holes are used for installing sensors, the multiple fixing holes are used for fixing circuits, the elastic cylinder is used to reduce the contact between two second detection frames, and the first detection frame, the second bolt, the second detection frame, the third bolt, the mounting plate, the elastic cylinder and the mounting frame are all made of non-metallic materials.

[0013] In a preferred embodiment, the lifting mechanism includes two support frames rotatably connected to the edge of the upper surface of one side of the bottom plate. A fixed rail is fixedly connected to the upper surface of the support frame. Two sliders are slidably connected to the upper surface of the fixed rail.

[0018] As can be seen from the above, a transformer core discharge detection device provided by the present invention has the following technical effects.

[0019] Firstly: By rotating the first handle, the first threaded cylinder gradually approaches one end of the first fixing plate, so that the second connecting strip drives the vertical frame to rotate, drives the second threaded cylinder and the detection mechanism to move vertically, and discharges the vertical iron core of the transformer through the detection mechanism. By manually rotating the second handle, the horizontal frame is pushed to rotate through the first connecting strip, so that the horizontal frame gradually rotates to the horizontal. Through this folding design, the device can quickly and accurately detect the discharge of the transformer core. Compared with large-scale devices, it has a simple structure and is easy to use. Compared with manual detection, the structure is more accurate and reliable.

[0020] Second: By detecting that the positions of the first detection frame and the second detection frame on the detection mechanism cannot be aligned with the horizontal iron core at the bottom of the transformer, by rotating the adjustment handle, the bidirectional threaded rod is driven to rotate. Through the threaded connection between the bidirectional threaded rod and the sliders at both ends, the sliders are driven to move relative to each other or in the opposite direction, driving the movement of multiple connecting plates, so that the positions of the lifting block and the lifting plate rise or fall, thereby adjusting the height of the transformer, aligning the positions of the first detection frame and the second detection frame with the horizontal iron core at the bottom of the transformer, and achieving the effect of adjusting the position of the transformer.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] A transformer core discharge detection device disclosed by the present invention is mainly applied to the scenario where the general method for detecting a transformer core is to detect it through large-scale detection equipment or manual detection. The large-scale detection equipment has a complex structure and is difficult to operate, while the manual detection has low accuracy.

[0032] Referring to Figure 1 — Figure 8 , a transformer core discharge detection device includes a bottom plate 1. Two second fixing plates 27 are fixedly connected to the upper surface of the bottom plate 1. One side of the second fixing plate 27 is rotatably connected to a first threaded rod 13. One end of the first threaded rod 13 is threadedly connected to a first threaded barrel 14. The other end of the first threaded rod 13 is fixedly connected to a first handle 12. One side of the first threaded barrel 14 is rotatably connected to a second connecting bar 26. A first fixing plate 23 is fixedly connected to the position near the second fixing plate 27 on the upper surface of the bottom plate 1 away from the first handle 12. One side of the first fixing plate 23 is rotatably connected to a vertical frame 20. One side of the vertical frame 20 is rotatably connected to a third threaded rod 19. One end of the third threaded rod 19 is threadedly connected to a third threaded barrel 22. One end of the third threaded rod 19 is fixedly connected to a second handle 24. One side of the third threaded barrel 22 is rotatably connected to a first connecting bar 21. The top end of the vertical frame 20 is rotatably connected to a horizontal frame 18. One side of the horizontal frame 18 is rotatably connected to a second threaded rod 17. One end of the second threaded rod 17 is threadedly connected to a second threaded barrel 16. The other end of the second threaded rod 17 is fixedly connected to a motor 25. A slide rail is fixedly connected to the position between the second threaded barrel 16 and the horizontal frame 18 on one side of the horizontal frame 18;

[0033] A detection mechanism is installed on one side of the second threaded cylinder 16, and the detection mechanism is used to detect the discharge condition of the transformer core;

[0034] A lifting mechanism is installed at one side edge position of the bottom plate 1, and the lifting mechanism is used to adjust the position of the transformer core.

[0035] The other end of the second connecting bar 26 is rotatably connected to one side of the vertical frame 20, the motor 25 is fixedly connected to the bottom end of the horizontal frame 18, one end of the first connecting bar 21 is rotatably connected to one side of the horizontal frame 18, and one side of the second threaded cylinder 16 is slidably connected to the slide rail.

[0036] In this embodiment, manually rotate the first handle 12 to move the first threaded cylinder 14 to a position close to the first handle 12, so that the second connecting bar 26 drives the vertical frame 20 to rotate, and the vertical frame 20 rotates to the horizontal. At this time, the position of the detection mechanism is exactly at the horizontal core position at the bottom of the transformer. Start the motor 25 to drive the second threaded cylinder 16 and the detection mechanism to move horizontally, and perform a discharge detection on the horizontal core at the bottom of the transformer through the detection mechanism.

[0037] Furthermore, when it is necessary to detect several vertical cores on the transformer, rotate the first handle 12 to gradually move the first threaded cylinder 14 closer to one end of the first fixing plate 23, so that the second connecting bar 26 drives the vertical frame 20 to rotate, and the vertical frame 20 gradually becomes vertical. After the vertical frame 20 is completely vertical, start the motor 25 to drive the second threaded cylinder 16 and the detection mechanism to move vertically, and perform a discharge detection on the vertical cores of the transformer through the detection mechanism. When it is necessary to detect the horizontal core at the top of the transformer, manually rotate the second handle 24 to drive the third threaded cylinder 22 to move vertically, and push the horizontal frame 18 to rotate through the first connecting bar 21, so that the horizontal frame 18 gradually rotates to the horizontal, and the detection mechanism is in the horizontal position. Similarly, start the motor 25 to perform a discharge detection on the horizontal core at the top of the transformer. Through this folding design, the device can quickly and accurately perform a discharge detection on the transformer core, is simpler in structure and more convenient to use compared with large equipment, and is more accurate and reliable in structure compared with manual detection.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8, in a preferred embodiment, the detection mechanism includes a detection disc 15 fixedly connected to one side of the second threaded cylinder 16. A rotating seat 28 is rotatably connected to one side of the detection disc 15. A positioning bolt 29 is threadedly connected to the top of the rotating seat 28. A plurality of first detection frames 31 are respectively rotatably connected to one side of the rotating seat 28. A first bolt 30 is threadedly connected to one end of the first detection frame 31, and a second bolt 32 is threadedly connected to the other end of the first detection frame 31. A second detection frame 33 is rotatably connected to a position near the second bolt 32 at the other end of the first detection frame 31.

[0039] A third bolt 34 is threadedly connected to one end of the second detection frame 33. An elastic cylinder 36 is rotatably connected to the position of the third bolt 34 at one end of the second detection frame 33. Mounting plates 35 are respectively fixedly connected to one side of the first detection frame 31 and the second detection frame 33. Two mounting brackets 37 are fixedly connected to one side of the mounting plate 35. A plurality of detection holes 38 are respectively arranged on the bottom surface of the mounting bracket 37, and a plurality of fixing holes 39 are arranged at positions near the detection holes 38 on the bottom surface of the mounting bracket 37.

[0040] The plurality of detection holes 38 are used for installing sensors, the plurality of fixing holes 39 are used for fixing circuits, the elastic cylinder 36 is used to reduce the contact between the two second detection frames 33, and the first detection frame 31, the second bolt 32, the second detection frame 33, the third bolt 34, the mounting plate 35, the elastic cylinder 36 and the mounting bracket 37 are all made of non-metallic materials.

[0041] In this embodiment, before the detection mechanism detects the iron core, the position of the detection mechanism needs to be set. By rotating the rotating seat 28, the first detection frames 31 are respectively located on both sides of the iron core. By rotating the positioning bolt 29, the positioning bolt 29 contacts the detection disc 15, thereby fixing the position of the rotating seat 28. The first detection frames 31 and the second detection frames 33 on both sides are respectively rotated so that the iron core is located between the first detection frame 31 and the second detection frame 33. The sensors of the first detection frame 31 and the second detection frame 33 can detect the change of the current inside the iron core. Since most parts of the detection mechanism are made of plastic, the influence on the current inside the iron core can be reduced. If there is rust and local oxidation inside the iron core, the current will show obvious abnormalities, and local maintenance is required to ensure the normal operation of the transformer.

[0042] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in a preferred embodiment, the lifting mechanism includes two support frames 2 rotatably connected to the edge of the upper surface of one side of the bottom plate 1. A fixed rail 8 is fixedly connected to the upper surface of the support frame 2. Two sliders 9 are slidably connected to the upper surface of the fixed rail 8. A bidirectional threaded rod 7 is threadedly connected through one side of the slider 9.

[0043] One end of the bidirectional threaded rod 7 is fixedly connected with an adjusting handle 10. Connecting plates are respectively rotatably connected to both sides of the slider 9. One end of each connecting plate is rotatably connected with a lifting block 11. The connecting plates are made of metal.

[0044] The connecting plates are respectively located on both sides of the slider 9. The threads at both ends of the bidirectional threaded rod 7 are reverse. Rotating the bidirectional threaded rod 7 can drive the sliders 9 at both ends to move relatively or in the opposite direction.

[0045] In this embodiment, the positions of the first detection frame 31 and the second detection frame 33 on the detection mechanism cannot be aligned with the horizontal iron core at the bottom of the transformer. By rotating the adjusting handle 10, the bidirectional threaded rod 7 is driven to rotate. Through the threaded connection between the bidirectional threaded rod 7 and the sliders 9 at both ends, the sliders 9 are driven to move relatively or in the opposite direction, driving the movement of multiple connecting plates, so that the positions of the lifting blocks 11 and the lifting plate 3 rise or fall, thereby adjusting the height of the transformer, aligning the positions of the first detection frame 31 and the second detection frame 33 with the horizontal iron core at the bottom of the transformer, achieving the effect of adjusting the position of the transformer.

[0046] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, a handle 5 is fixedly connected to the edge position at one end of the upper surface of the bottom plate 1. Universal wheels 6 are respectively rotatably connected to the four corners of the bottom of the bottom plate 1. A lifting plate 3 is fixedly connected to the upper surface of the lifting block 11. A transformer iron core 4 is arranged on the upper surface of the lifting plate 3.

[0047] The transformer iron core 4 is the core component of the transformer. An insulating coating is arranged on the outside of the transformer iron core 4.

[0048] In this embodiment, the transformer iron core 4 can be placed on the upper surface of the lifting plate 3. The transformer iron core 4 can be transferred by a crane or a lifting device. Conductors are arranged on the transformer iron core 4 and the conductors are energized to make there be current inside the transformer iron core 4. When it is necessary to detect the horizontal iron core at the bottom of the transformer iron core 4, it is detected by the detection mechanism.

[0049] Working principle: When in use, place the transformer core 4 on the upper surface of the lifting plate 3. The transformer core 4 can be transferred by a crane or a lifting device. Set wires on the transformer core 4 and energize the wires to make there be current inside the transformer core 4. When it is necessary to detect the horizontal core at the bottom of the transformer core 4, manually rotate the first handle 12 to move the first threaded cylinder 14 to a position close to the first handle 12, so that the second connecting bar 26 drives the vertical frame 20 to rotate, and makes the vertical frame 20 rotate to the horizontal. At this time, the position of the detection mechanism is exactly at the position of the horizontal core at the bottom of the transformer core 4. Start the motor 25 to drive the second threaded cylinder 16 and the detection mechanism to move horizontally, and perform discharge detection on the horizontal core at the bottom of the transformer core 4 through the detection mechanism. When it is necessary to detect several vertical cores on the transformer core 4, rotate the first handle 12 to gradually move the first threaded cylinder 14 closer to one end of the first fixing plate 23, so that the second connecting bar 26 drives the vertical frame 20 to rotate, and the vertical frame 20 gradually becomes vertical. After the vertical frame 20 is completely vertical, start the motor 25 to drive the second threaded cylinder 16 and the detection mechanism to move vertically, and perform discharge detection on the vertical cores of the transformer core 4 through the detection mechanism. When it is necessary to detect the horizontal core at the top of the transformer core 4, manually rotate the second handle 24 to drive the third threaded cylinder 22 to move vertically, and push the horizontal frame 18 to rotate through the first connecting bar 21, so that the horizontal frame 18 gradually rotates to the horizontal and makes the detection mechanism in the horizontal position. Similarly, start the motor 25 to perform discharge detection on the horizontal core at the top of the transformer core 4. Through this folding design, the device can quickly and accurately perform discharge detection on the transformer core. Compared with large-scale devices, it has a simple structure and is easy to use. Compared with manual detection, the structure is more accurate and reliable. Before the detection mechanism detects the core, it is necessary to set the position of the detection mechanism. Rotate the rotating seat 28 to make the first detection frame 31 located on both sides of the core respectively. Rotate the positioning bolt 29 to make the positioning bolt 29 contact the detection disc 15, thereby fixing the position of the rotating seat 28. Rotate the first detection frame 31 and the second detection frame 33 on both sides respectively to make the core located between the first detection frame 31 and the second detection frame 33. The sensors of the first detection frame 31 and the second detection frame 33 can detect the change of the current inside the core. Since most parts of the detection mechanism are made of plastic, the influence on the current inside the core can be reduced. If there is rust and local oxidation inside the core, the current will show obvious abnormalities, and it is necessary to repair the local area to ensure the normal operation of the transformer. After the transformer core 4 is placed on the lifting plate 3, the positions of the first detection frame 31 and the second detection frame 33 on the detection mechanism cannot be aligned with the horizontal core at the bottom of the transformer core 4. Rotate the adjustment handle 10 to drive the bidirectional threaded rod 7 to rotate. Through the threaded connection between the bidirectional threaded rod 7 and the sliders 9 at both ends, drive the sliders 9 to move relative to each other or in the opposite direction, drive the movement of multiple connecting plates, and make the positions of the lifting block 11 and the lifting plate 3 rise or fall.Thus, the height of the transformer core 4 is adjusted, so that the positions of the first detection frame 31 and the second detection frame 33 are aligned with the core horizontally at the bottom of the transformer core 4, achieving the effect of adjusting the position of the transformer core 4.
