Description

Technical Field

[0001] The present invention relates to the technical field of transformer protection, in particular to a transformer protection device and a protection method thereof. Background Art

[0002] A transformer is an electrical device used to convert voltage levels in an electric power system. The basic principle is electromagnetic induction, which increases or decreases voltage by transferring electrical energy between two or more windings. Transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and other places. Simply put, a transformer refers to a transformer whose core and windings are not immersed in insulating oil. When the transformer is in use, due to poor protection, the transformer is exposed for a long time, which can easily reduce the service life of the transformer due to external factors. Therefore, a corresponding protective cover is required.

[0003] However, the existing protective cover cannot hold the transformer in place during the process of protecting the transformer.

[0015] A protection method for transformer protection equipment comprises the following steps:

[0016] Step 1: Place the transformer at the top center of the platform, then the staff picks up the protective shell and docks it with the platform, allowing the protective shell to drop vertically along the outer wall of the platform. The protective shell drives the horizontal plate in the stable protection mechanism to contact the top of the transformer;

[0017] Step 2: Under the reaction force of the transformer, the horizontal plate moves upward, and the horizontal plate drives the rotating rod to move upward. Under the limit of the fixed rod, the rotating rod drives the slider to slide along the outer wall of the fixed rod, and the two sliders approach each other, and the slider drives the fixed frame to move;

[0018] Step 3: The fixed frame drives the clamping shell to move, the clamping shell drives the sliding plate to move, the sliding plate drives the round rod to move, the round rod drives the clamping plate to move, and the two clamping plates move closer to each other;

[0019] Step 4: During the movement of the clamping shell, the clamping shell drives the cross bar to move, and the cross bar drives the extrusion plate to move. During the movement of the extrusion plate, the extrusion plate will come into contact with the fixed plate, the fixed plate is squeezed, and the fixed plate drives the flexible card plate to move.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the transformer is placed at the top center of the load-bearing platform, and then the staff lifts the protective shell to dock with the load-bearing platform, so that the protective shell is vertically lowered along the outer wall of the load-bearing platform, so that the protective shell protects the transformer. The protective shell drives the horizontal plate in the stable protection mechanism to contact the top of the transformer, and the horizontal plate is subjected to the reaction force of the transformer to move upward, and the horizontal plate drives the rotating rod to move upward. The rotating rod is limited by the fixed rod, and the sliding block is driven by the rotating rod to slide along the outer wall of the fixed rod. The two sliding blocks approach each other, and the sliding block drives the fixed frame to move, and the fixed frame drives the clamping shell to move, and the clamping shell drives the sliding plate to move. The sliding plate drives the round rod to move, and the round rod drives the clamping plate to move, and the two clamping plates approach each other, thereby clamping both sides of the transformer to prevent the position of the transformer from shifting during the installation of the protective shell, and the side surface improves the protection effect of the device on the transformer. In the process of moving the clamping shell, the clamping shell drives the cross bar to move, and the cross bar drives the extrusion plate to move. The extrusion plate will contact the fixed plate during the movement, and the fixed plate will be squeezed. The fixed plate drives the flexible card plate to move, so that the flexible card plate is clamped on the bottom of the bearing platform to prevent the protective shell from shaking after the installation is completed, thereby improving the protection stability of the protective shell to the transformer.

[0022] (2) According to the present invention, when the clamping plate clamps the transformer, it is subjected to the reaction force of the transformer, and the clamping plate drives the round rod to move toward the inside of the clamping shell, and the round rod drives the sliding plate to move, and the sliding plate drives the rotating bar to move. Due to the setting of the limiting hole, the rotating bar drives the block to move along the outer wall of the limiting hole, and the two blocks approach each other. The square block drives the horizontal bar to move, and the horizontal bar drives the connecting frame to move. During the movement of the connecting frame, the connecting frame will come into contact with the rectangular block. During the movement of the rectangular block, the connecting frame drives the rectangular block to move, and the rectangular block will come into contact with the side wall of the transformer, thereby further preventing the position of the transformer from shifting during the installation process, and indirectly improving the stability of the transformer during subsequent work.

[0023] (3) In the present invention, when the rectangular block moves, the rectangular block drives the fixed column to move, and the fixed column drives the movable plate to move. When the movable plate moves away from the condensing plate, the movable plate no longer blocks the circular hole set at the cooling box. Due to the setting of the condensing plate, the condensing plate converts the airflow inside the cooling box into cold air. At this time, the cold air inside the cooling box enters the inside of the protective shell through the circular hole to cool the working transformer. Due to the setting of the exhaust hole on the top of the supporting platform, when the cold air cools the transformer, the converted airflow is discharged to the outside through the exhaust hole to prevent the transformer from being affected by the low temperature. When the protective shell is not installed with the supporting platform, it is elastically deformed by the tension spring, and the tension spring drives the movable plate to approach the condensing plate. When it moves to one end of the cooling box, the movable plate blocks the circular hole at the cooling box to prevent the cold air from being discharged when it is not installed.

[0024] (4) According to the present invention, when the rectangular block moves toward the transformer, it is affected by the oblique side setting of the rectangular block and the oblique block. During the movement of the rectangular block, the rectangular block will come into contact with the oblique block, squeezing the oblique block, causing the oblique block to drive the vertical rod to move downward, and the vertical rod to drive the vertical plate to move downward. During the downward movement of the vertical plate, the vertical plate will come into contact with the top of the flexible cardboard, slightly pressing the flexible cardboard downward, causing the flexible cardboard to be slightly bent. The flexible cardboard bends at the connection between the protective shell and the flexible cardboard itself, thereby improving the clamping effect of the flexible cardboard on the protective shell, and further improving the protective effect of the protective shell on the transformer.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] A protection method for transformer protection equipment comprises the following steps:

[0051] Step 1: Place the transformer 3 at the top center of the platform 1, then the staff picks up the protective shell 4 and docks it with the platform 1, so that the protective shell 4 drops vertically along the outer wall of the platform 1, and the protective shell 4 drives the horizontal plate 54 in the stable protection mechanism 5 to contact the top of the transformer 3;

[0052] Step 2: Under the reaction force of the transformer 3, the horizontal plate 54 moves upward, and the horizontal plate 54 drives the rotating rod 53 to move upward. Under the limit of the fixed rod 51, the rotating rod 53 drives the slider 52 to slide along the outer wall of the fixed rod 51, and the two sliders 52 approach each other, and the slider 52 drives the fixed frame 551 to move;

[0054] Step 4: During the movement of the clamping shell 552, the clamping shell 552 drives the cross bar 558 to move, and the cross bar 558 drives the extrusion plate 559 to move. During the movement of the extrusion plate 559, it will come into contact with the fixed plate 5511, and the fixed plate 5511 will be squeezed, and the fixed plate 5511 drives the flexible card plate 5512 to move.

[0055] When in use, the transformer 3 is placed at the top center of the supporting platform 1, and then the staff lifts the protective shell 4 to dock with the supporting platform 1, so that the protective shell 4 is vertically lowered along the outer wall of the supporting platform 1, so that the protective shell 4 protects the transformer 3, and the protective shell 4 drives the cross plate 54 in the stable protection mechanism 5 to contact the top of the transformer 3, and the reaction force of the transformer 3 causes the cross plate 54 to move upward, and the cross plate 54 drives the rotating rod 53 to move upward, and is limited by the fixed rod 51, and the rotating rod 53 drives the slider 52 to slide along the outer wall of the fixed rod 51, and the two sliders 52 approach each other, and the slider 52 drives the fixed frame 551 to move, and the fixed frame 551 drives the clamping shell 552 to move, and the clamping shell 552 drives the sliding plate 554 to move, and the sliding plate 554 drives the circular The rod 556 moves, and the round rod 556 drives the clamping plate 557 to move, and the two clamping plates 557 approach each other, so as to clamp the two sides of the transformer 3, so as to prevent the position of the transformer 3 from being offset during the installation of the protective shell 4, and the side surface improves the protection effect of the device on the transformer 3. In the process of moving the clamping shell 552, the clamping shell 552 drives the cross bar 558 to move, and the cross bar 558 drives the extrusion plate 559 to move. During the movement of the extrusion plate 559, it will contact the fixed plate 5511, and the fixed plate 5511 is squeezed. The fixed plate 5511 drives the flexible card board 5512 to move, so that the flexible card board 5512 is clamped on the bottom of the supporting platform 1, so as to prevent the protective shell 4 from shaking after the installation is completed, and improve the protection stability of the protective shell 4 on the transformer 3.

[0056] When the clamping plate 557 clamps the transformer 3, it is subjected to the reaction force of the transformer 3, and the clamping plate 557 drives the round rod 556 to move toward the inside of the clamping shell 552, and the round rod 556 drives the sliding plate 554 to move, and the sliding plate 554 drives the rotating bar 561 to move. Due to the setting of the limiting hole 563, the rotating bar 561 drives the block 562 to move along the outer wall of the limiting hole 563, and the two blocks 562 approach each other, and the block 562 drives the horizontal bar 564 to move, and the horizontal bar 564 drives the connecting frame 565 to move. During the movement of the connecting frame 565, it will contact the rectangular block 576, and the connecting frame 565 drives the rectangular block 576 to move. During the movement, the rectangular block 576 will contact the side wall of the transformer 3, further preventing the position of the transformer 3 from shifting during the installation process, and improving the stability of the transformer 3 in subsequent work.

[0057] When the rectangular block 576 moves, the rectangular block 576 drives the fixed column 575 to move, and the fixed column 575 drives the movable plate 574 to move. When the movable plate 574 moves away from the condensing plate 572, the movable plate 574 no longer blocks the circular hole 577 set at the cooling box 571. Due to the setting of the condensing plate 572, the condensing plate 572 converts the airflow inside the cooling box 571 into cold air. At this time, the cold air inside the cooling box 571 enters the interior of the protective shell 4 through the circular hole 577, and cools the working transformer 3. Processing, affected by the setting of the exhaust hole 585 on the top of the supporting platform 1, when the cold air cools down the transformer 3, the converted airflow is discharged to the outside through the exhaust hole 585 to prevent the low temperature from affecting the operation of the transformer 3. When the protective shell 4 is not installed with the supporting platform 1, it is elastically deformed by the tension spring 573, and the tension spring 573 drives the movable plate 574 to approach the condensation plate 572. When it moves to one end inside the cooling box 571, the movable plate 574 will block the circular hole 577 at the cooling box 571 to prevent the cold air from being discharged to the outside when it is not installed.

[0058] When the rectangular block 576 moves toward the transformer 3, due to the oblique side setting of the rectangular block 576 and the oblique block 582, the rectangular block 576 will come into contact with the oblique block 582 during the movement, squeezing the oblique block 582, so that the oblique block 582 drives the vertical rod 583 to move downward, and the vertical rod 583 drives the vertical plate 584 to move downward. During the downward movement of the vertical plate 584, it will come into contact with the top of the flexible card board 5512, slightly press the flexible card board 5512 downward, so that the flexible card board 5512 is slightly bent, and the flexible card board 5512 is bent at the connection between the protective shell 4 and the flexible card board 5512 itself, thereby improving the clamping effect of the flexible card board 5512 on the protective shell 4, and further improving the protective effect of the protective shell 4 on the transformer 3.
