Description

Technical Field

[0001] The invention relates to the technical field of transformer maintenance equipment, in particular to transformer maintenance equipment used for power engineering maintenance. Background Art

[0002] Power engineering maintenance refers to the maintenance of power equipment and power systems to ensure their effective operation. Transformer is an electrical device mainly used to change the voltage level in the AC system. It uses the principle of electromagnetic induction to increase or decrease the voltage through the magnetic coupling between the primary coil and the secondary coil. However, transformers need to be regularly maintained by maintenance equipment during use to achieve long-term use of transformers and reduce the occurrence of transformer failures during use.

[0003] However, the existing maintenance equipment also has the following defects during the maintenance process:

[0004] 1. During maintenance, the transformer needs to be tested for temperature (used to identify whether the transformer is overheated during use), insulation performance, vibration (used to evaluate mechanical failures) and oil properties (evaluate the insulation performance and deterioration degree of the oil) to ensure the normal operation of the transformer. However, due to the excessive types of transformer maintenance, the number of transformer maintenance equipment increases, which makes it inconvenient for maintenance personnel to carry maintenance equipment. In addition, during maintenance, too much maintenance equipment occupies the maintenance personnel's operating space, making it inconvenient for maintenance personnel to maintain the transformer.

[0005] 2. During maintenance, the dust and dirt on the surface of the transformer need to be cleaned regularly to provide a good working environment for the transformer. Before maintenance, the maintenance personnel need to clean the surface of the transformer. Since most transformers are installed outdoors, there are various dirt on their surfaces, such as animal feces, plant leaves, and organic dust in the air. Therefore, different cleaning tools need to be used for cleaning. The cleaning tools are small in size, and maintenance personnel are prone to miss some cleaning tools when carrying them, which makes it difficult to achieve the best cleaning quality when cleaning the transformer, and then the transformer surface is not thoroughly cleaned.

Before using the bellows to vacuum, use a soft brush to loosen or remove the dust accumulated on the surface of the transformer, so that the key components of the transformer are clearly visible, so that the bellows can better vacuum. The soft brush is relatively soft, which effectively reduces the damage to the insulation layer on the surface of the transformer. After vacuuming, use a semi-wet treatment sleeve to wipe it, so that the bellows itself has a variety of cleaning methods, which improves the practicality of the bellows. At the same time, when cleaning the surface of the transformer with different degrees of pollution, it can reduce the time of replacing different cleaning tools and reduce the risk of misoperation due to frequent tool replacement. The cleaning tools are easy to carry and store. At the same time, a drainage cavity is opened inside the bellows, and the degree of wetting of the treatment sleeve by alcohol is controlled by the control block to prevent the treatment sleeve from being too wet, thereby controlling the wet state of the transformer surface after cleaning, which is beneficial to extend the service life of the transformer.

[0044] As a preferred implementation in this embodiment, Figure 4 , Figure 5 and Figure 6 As shown, the switching mechanism includes a turntable 31 and a limiting frame 33. The turntable 31 is arranged at the top of the maintenance box 1. The bottom end of the turntable 31 is fixedly connected to a rotating shaft 32. The rotating shaft 32 passes through the top of the turntable 31. The top of the limiting frame 33 is provided with a limiting groove for the rotating shaft 32 to pass through.

[0045] Compared with the prior art, during maintenance, the present invention can switch different detection equipment according to the detection of different conditions on the transformer surface, which is beneficial to reducing the number of independent equipment that maintenance personnel need to carry during maintenance. At the same time, before detection, the transformer surface is cleaned by combining three different cleaning methods, namely, the bellows 53, the processing sleeve 58 and the soft brush 515, to ensure the cleanliness and wetness of the transformer surface, and integrate the three methods, which is beneficial to the operation of maintenance personnel. At the same time, the soft brush 515 with the bristles installed in the wrong direction can loosen the transformer surface more comprehensively to prevent the bristles on the existing soft brush 515 from being missed due to the neat arrangement.

[0046] It should be noted that when the storage box 51 is installed, a micro-delivery pump is installed inside the storage box 51 , and the outlet of the micro-delivery pump is connected to the end of the L-shaped tube 52 away from the bellows 53 .

[0047] Working principle:

[0048] Initial limit:

[0049] Before using the present invention, the user needs to manually pull the integrated handle on the door 2 to open the door 2. Figure 2As shown, the user manually rotates the integrated sealing plug at the top of the storage box 51 counterclockwise. Since the integrated sealing plug is threadedly connected to the top of the storage box 51, it moves upward relying on the thread when the integrated sealing plug rotates counterclockwise. Under continuous counterclockwise rotation, the integrated sealing plug gradually separates from the top of the storage box 51. Then the user places the integrated sealing plug at other positions, places a funnel or other tools at the connection between the integrated sealing plug and the storage box 51, and injects alcohol into the storage box 51. When the user can observe the position of the alcohol through the tool, the injection is stopped, the tool is removed, and the integrated sealing plug is rotated clockwise to restore the integrated sealing plug to Figure 2 The state shown, its principle is consistent with the above;

[0050] When installing the detection equipment, the user needs to manually pull the integrated handle at the top of the limit plate 39 upwards to move the integrated handle upwards. When the integrated handle moves upwards, it drives the limit plate 39 upwards. When the limit plate 39 moves upwards, it drives the limit block 38 upwards. When the limit plate 39 moves upwards, it presses the spring 37 to deform the spring 37. Then the user places the required detection equipment on the top of the limit frame 310. After the placement is completed, the user releases the integrated handle, so that the limit block 38 loses the lifting force from the limit plate 39, and then the limit plate 39 moves downwards by the resilience of the spring 37. The limit plate 39 clamps the detection equipment when it moves downward. Under the double action of the limit plate 39 clamping downwards and the clamping hole on the limit frame 310, the detection equipment is installed inside the limit frame 310.

[0051] The user needs to install the dust collector on the top of the mounting plate 4, and connect the dust removal pipe of the dust collector to the end of the bellows 53 away from the control board 54. After the installation is completed, close the box door 2 and install the other parts as shown in the figure. Figures 1 to 9 Status shown;

[0052] Multiple cleaning steps:

[0053] First, the maintenance personnel lift the integrated handles on both sides of the maintenance box 1 and move the present invention to the vicinity of the transformer to be maintained and repaired. Then the user reopens the box door 2 in the same way as described above. The user manually pulls up the integrated handle at the top of the control panel 54, as shown in FIG. Figure 3 As shown, the integrated handle drives the control panel 54 to move upward when it moves upward, and the control panel 54 drives the L-shaped rod 55 to move upward when it moves upward, and the L-shaped rod 55 is separated from the slot on the socket 6 when it moves upward. When the L-shaped rod 55 is completely separated from the slot on the socket 6, and the present invention is facing the surface of the inner tube of the transformer, the user needs to align the end of the corrugated tube 53 away from the L-shaped tube 52 with the surface of the transformer, and put the processing sleeve 58 on the tube inside the transformer, as shown in FIG. Figure 8As shown, the maintenance personnel need to stick the sticky hair 59 on the outer surface of the processing sleeve 58 and the sticky hair 59 on the inner surface of the processing sleeve 58 together, and then the user turns on the power of the micro-transfer pump to start the micro-transfer pump. Figure 7 and Figure 8 As shown, the micro delivery pump delivers the alcohol in the storage box 51 to the inside of the L-shaped tube 52, and the alcohol is delivered from the inside of the L-shaped tube 52 to the drainage cavity in the bellows 53, and the alcohol is delivered from the drainage cavity to the inside of the catheter 56. At this time, the control block 512 is in the state as shown in FIG. Figure 8 Status shown;

[0054] like Fig. 9 As shown, the maintenance personnel need to manually rotate the positioning block 513 counterclockwise, and the positioning block 513 drives the integrated positioning sleeve at the bottom end of the positioning block 513 to rotate counterclockwise when rotating counterclockwise. Since the positioning block 513 is threadedly connected to the drive shaft 511, and the integrated positioning sleeve at the bottom end of the positioning block 513 is threadedly connected to the top of the positioning seat 514, the positioning block 513 moves upward by relying on the thread when rotating counterclockwise, and the integrated positioning sleeve at the bottom end of the positioning block 513 moves upward by relying on the thread when rotating counterclockwise, so that the integrated positioning sleeve at the bottom end of the positioning block 513 is separated from the top end of the positioning seat 514, thereby releasing the integrated positioning sleeve from the drive shaft. 511 is positioned, at this time the driving shaft 511 can be driven externally, and the maintenance personnel control the rotation angle of the driving block 510 according to the requirement of the wetness of the transformer surface. When the driving block 510 rotates, it drives the driving shaft 511 to rotate, and when the driving shaft 511 rotates, it drives the control block 512 to rotate, so that the alcohol flows to the inner cavity of the spray block 57 under the rotation of the positioning block 513, and then is guided out from the spray hole to the outer surface of the processing sleeve 58, so as to wet the entire processing sleeve 58. The maintenance personnel can control the content of alcohol introduced into the inner cavity of the spray block 57 through the conduit 56 according to the wetting requirements of the transformer, so as to control the wetness of the processing sleeve 58 itself;

[0055] At this time, the power of the dust collector is turned on, and the dust collector starts to work, so that the dust collection pipe generates suction, and the suction is introduced from the dust collection pipe into the inside of the bellows 53. Then the user holds the control panel 54 and slides along the internal pipe of the transformer to complete the cleaning of the transformer pipe surface. During the cleaning process, Figure 8As shown, the soft brush 515 is arranged in front of the processing sleeve 58 and the bellows 53, so the soft brush 515 is used to loosen the impurities or dust on the surface of the transformer pipe during sliding, which is beneficial to the subsequent absorption of the internal suction of the bellows 53. After the loosening treatment, the impurities or dust are absorbed into the dust removal pipe by the internal suction of the bellows 53, and then the impurities and dust are absorbed into the dust collector to complete the cleaning of the transformer surface. After the bellows 53 is dusted, the wet processing sleeve 58 is used to wipe it, so as to further improve the cleaning effect of the transformer surface and ensure its cleaning quality. At the same time, before the inspection, the three different cleaning methods of the bellows 53, the processing sleeve 58 and the soft brush 515 are combined to clean the transformer surface, which can ensure the neatness and wetness of the transformer surface, and the three methods are integrated, which is beneficial to the operation of the maintenance personnel.

[0056] By adopting a design in which the bristles of the soft brush 515 are arranged in a staggered direction, the problem that the bristles of the existing soft brush 515 are neatly arranged and there are gaps between the bristles, and the surface of the transformer cannot be fully treated, can be solved. Therefore, when loosening impurities or dust on the surface of the transformer, the present invention can more fully treat the surface of the transformer, thereby improving the adsorption effect of the bellows 53, and further improving its cleaning quality;

[0057] Switching steps:

[0058] After the surface of the transformer is cleaned, the maintenance personnel need to repeat the operation steps of the initial limit inner limit plate 39, take out the detection equipment, and perform maintenance inspection on the surface of the transformer. When the maintenance inspection is completed, the maintenance personnel need to switch to other detection equipment. At this time, the maintenance personnel will re-place the used equipment through the operation steps of the initial limit inner limit plate 39, and then manually rotate the turntable 31, such as Figure 5 As shown, the turntable 31 drives the rotating shaft 32 to rotate when it rotates, and the rotating shaft 32 drives the cross mounting frame 36 to rotate when it rotates, and the cross mounting frame 36 drives the limit frame 310 to rotate when it rotates, so that different detection devices can be taken at the same device taking place, and as shown in FIG. Figure 6 As shown, the rotating shaft 32 drives the hemispherical block 34 to rotate when rotating. The hemispherical block 34 is squeezed by the inner wall of the limiting groove when rotating. The hemispherical block 34 is pressed into the inside of the square groove. When being pressed, the hemispherical block 34 presses the elastic column 35, causing the elastic column 35 to deform. When the elastic column 35 rotates 90 degrees and faces other hemispherical grooves, the hemispherical block 34 is no longer squeezed by the inner wall of the limiting groove. The hemispherical block 34 rebounds into the hemispherical groove with the help of the rebound force of the elastic column 35, thereby fixing the rotating shaft 32.

[0059] The present invention installs the bellows 53 and the detection equipment inside the maintenance box 1, thereby reducing the number of independent equipment that needs to be carried and set up during maintenance, thereby alleviating the burden on the maintenance team. At the same time, the maintenance personnel will organize the used equipment during maintenance to avoid collisions between the various devices. At the same time, the storage space required for the equipment is reduced, which is convenient for maintenance personnel to carry. The clamping hole design can prevent the equipment from sliding during carrying. The cleaning tool of the present invention is installed in one piece, which can reduce the time of replacing different cleaning tools when cleaning the surface of the transformer with different degrees of pollution, reduce the risk of misoperation due to frequent tool replacement, and the cleaning tool is easy to carry and store.

Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
