Technical Field

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

[0002] The transformer core is the main magnetic circuit component of the transformer. It is usually made of stacked hot-rolled or cold-rolled silicon steel sheets with a high silicon content and a surface coating of insulating varnish. The core and the coils wound around it together form a complete electromagnetic induction system. The amount of power transmitted by the transformer depends on the material and cross-sectional area of ​​the core. The main material of the transformer core is silicon steel sheets. Silicon steel is used as the core of the transformer because it is a magnetic material with strong magnetic conductivity and can generate a large magnetic induction intensity in the energized coil.

[0003] The principle of transformer core discharge is based on electromagnetic induction and partial discharge. The main function of the transformer core is to conduct magnetism and form a magnetic circuit, so that electrical energy can be converted through the magnetic field. In the process of discharging the transformer core, the current change in the core is detected to detect whether the core is damaged. The general method of inspecting the transformer core is through large-scale inspection equipment or manual inspection. The structure of large-scale inspection equipment is complex and difficult to operate, and the accuracy of manual inspection is not high. Both methods cannot meet the requirements of outdoor transformer core inspection. Summary of the Invention

[0033] Reference Figure 1 、 Figure 2 、 Figure 7 and Figure 8 In a preferred embodiment, the detection mechanism includes a detection disk 15 fixedly connected to one side of the second threaded cylinder 16, one side of the detection disk 15 is rotatably connected to a rotating seat 28, the top of the rotating seat 28 is threadedly connected to a positioning bolt 29, and one side of the rotating seat 28 is rotatably connected to multiple first detection frames 31, one end of the first detection frame 31 is threadedly connected to a first bolt 30, the other end of the first detection frame 31 is threadedly connected to a second bolt 32, and the other end of the first detection frame 31 is rotatably connected to a second detection frame 33 near the second bolt 32.

One side of the first detection frame 31 and the second detection frame 33 are respectively fixedly connected to the mounting plate 35, and one side of the mounting plate 35 is fixedly connected to two mounting frames 37. The bottom surface of the mounting frame 37 is respectively provided with a plurality of detection holes 38, and the bottom surface of the mounting frame 37 is provided with a plurality of fixing holes 39 near the detection holes 38.

[0036] 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 frame 31 is located on both sides of the iron core respectively. By rotating the positioning bolt 29, the positioning bolt 29 is contacted with the detection disk 15, thereby fixing the position of the rotating seat 28, and the first detection frame 31 and the second detection frame 33 on both sides are rotated respectively 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 changes in the current inside the iron core. Since most parts of the detection mechanism are made of plastic, the impact on the current inside the iron core can be reduced. If rust and local oxidation occur inside the iron core, the current will be obviously abnormal, and local maintenance is required to ensure the normal operation of the transformer.

[0039] 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 in opposite directions. The rotation of the bidirectional threaded rod 7 can drive the sliders 9 at both ends to move relative to each other or move in opposite directions.

[0040] 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 adjustment handle 10, the bidirectional threaded rod 7 is driven to rotate, and the bidirectional threaded rod 7 is threadedly connected to the sliders 9 at both ends to drive the sliders 9 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 11 and the lifting plate 3 are raised or lowered, thereby adjusting the height of the transformer, so that the positions of the first detection frame 31 and the second detection frame 33 are aligned with the horizontal iron core at the bottom of the transformer, thereby achieving the effect of adjusting the position of the transformer.

The upper surface of the lifting block 11 is fixedly connected to the lifting plate 3, and the upper surface of the lifting plate 3 is provided with a transformer core 4.

[0042] The transformer core 4 is the core component of the transformer, and an insulating coating is provided on the outside of the transformer core 4 .

[0043] In this embodiment, the transformer core 4 is placed on the upper surface of the lifting plate 3, and the transformer core 4 can be transferred by a crane or lifting equipment. A wire is set on the transformer core 4, and the wire is energized to pass current inside the transformer core 4. When the horizontal core at the bottom of the transformer core 4 needs to be detected, it is detected by a detection mechanism.

[0044] 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 lifting equipment, and a wire is set on the transformer core 4, and the wire is energized 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 barrel 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 is rotated 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 core 4, start the motor 25, drive the second threaded barrel 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 inspect several vertical cores on the transformer core 4, the first handle 12 is rotated to make the first threaded barrel 14 gradually approach one end of the first fixed 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, the motor 25 is started to drive the second threaded barrel 16 and the detection mechanism to move vertically, and the detection mechanism is used to perform discharge detection on the vertical cores of the transformer core 4. When it is necessary to detect the horizontal core at the top of the transformer core 4, the second handle 24 is manually rotated to drive the third threaded barrel 22 to move vertically, and the horizontal frame 18 is pushed to rotate through the first connecting bar 21, so that the horizontal frame 18 gradually rotates to the horizontal, so that the detection mechanism is in a horizontal position. Similarly, by starting the motor 2 5. Perform discharge detection on the horizontal core at the top of the transformer core 4. Through this folding design, the equipment can quickly and accurately perform discharge detection on the transformer core. Compared with large equipment, it has a simple structure and is easy to use. Compared with the manual detection structure, it is more accurate and reliable. Before the detection mechanism detects the core, it is necessary to set the position of the detection mechanism. By rotating the rotating seat 28, the first detection frame 31 is located on both sides of the core respectively. By rotating the positioning bolt 29, the positioning bolt 29 is contacted with the detection disk 15, thereby fixing the position of the rotating seat 28. The first detection frame 31 and the second detection frame 33 on both sides are rotated respectively, so that the 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 impact on the current inside the iron core can be reduced. If rust and local oxidation occur inside the iron core, the current will be obviously abnormal, and local maintenance is required 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 iron core at the bottom of the transformer core 4. By rotating the adjustment 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 relative to each other or in the opposite direction, driving the movement of multiple connecting plates, so that the position of the lifting block 11 and the lifting plate 3 rises or falls.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 horizontal core at the bottom of the transformer core 4, thereby achieving the effect of adjusting the position of the transformer core 4.
