Description

Technical Field

[0001] The invention relates to the technical field of power transformers, in particular to a dry-type power transformer with a spiral heat dissipation pipe. Background Art

[0002] The dry-type power transformer with spiral heat pipe adopts spiral heat pipe, which can effectively improve the heat dissipation performance of the transformer and ensure the stability and reliability of the equipment during long-term operation. The spiral heat pipe is generally installed above the iron core or winding of the transformer. Its spiral structure increases the surface area of ​​the heat pipe, which helps to dissipate heat faster. It is more common in dry-type power transformers.

[0003] Prior art, such as the invention with publication number CN117672691B, discloses a dry-type power transformer, which includes a tap terminal. The copper bar connected to two tap terminals can change the effective number of turns of the winding. Limiting pieces are connected to both sides of the copper bar. The limiting pieces are threadedly connected to the copper bar through connecting columns. When the copper bar rotates, the limiting piece on one side moves toward the tap terminal, and the limiting piece on the other side moves away from the tap terminal. A spherical protrusion and a spherical groove are provided between the tap terminal and the copper bar, respectively. In this dry-type power transformer, the tap terminal and the pressure plate form a truncated cone, which reduces the height of the tap terminal and keeps the structural strength of the tap terminal at a high level. At the same time, the copper bar and the limiting piece are pressed on the tap terminal by pressure, further ensuring the structural integrity of the tap terminal. Secondly, when adjusting the voltage gear, the three phases are adjusted at the same time to ensure their consistency. Under the constraints of the limiting piece and the positioning frame, both the gear adjustment can be achieved and the reliability of the gear adjustment can be ensured.

[0004] It is found in dry-type power transformers that when the dry-type transformer is operated for a long time, a large amount of heat will be generated in the transformer, which requires the use of spiral heat dissipation pipes for auxiliary heat dissipation.

Both ends of the inner wall of the connecting frame 607 are sleeved with coil springs 608, and the two ends of the coil spring 608 are respectively fixedly connected to the connecting frame 607 and the rotating plate 609.

[0046] The effect achieved by the entire adjustment device 6 is to limit the docking of the heat pipe body 9 and the circulator 4 that have been used for a long time, by using the slide rail 601 on the surface of the support base 1 and the slide plate 602 on the lower surface of the mounting frame 5 for sliding insertion, and then using the positioning column 605 on one side of the support base 1 and the rotating plate 609 and the positioning column 605 on one side of the mounting frame 5 for insertion and fixing, thereby effectively and conveniently limiting the position of the entire mounting frame 5.

[0047] like Figure 6 and Figure 7 As shown, the moving device 7 includes a connecting plate 71, the upper surface of the connecting plate 71 is fixedly connected to the lower surface of the support seat 1, and a sliding groove 72 is opened on the lower surface of the connecting plate 71. Moving blocks 76 are slidably connected to both sides of the inner wall of the sliding groove 72, and the lower surface of the moving block 76 is fixedly connected to a support rod 74, and the side surfaces of the two moving blocks 76 close to each other are rotatably connected to a rotating rod 77, and the bottom ends of the two rotating rods 77 are rotatably connected to the same driving frame 78, and the inner wall thread of the driving frame 78 is penetrated by a driving rod 73, the upper end arc surface of the driving rod 73 is rotatably connected to the surface of the connecting plate 71, and the bottom end of the driving rod 73 is rotatably connected to the pulley frame 79, and the lower surface of the support rod 74 is fixedly connected to a supporting pad 75, the supporting pad 75 is a rubber pad, and the rotating rod 77 is a carbide rod. The length of the rotating rod 77 is adapted to the length of the driving rod 73.

[0048] The effect achieved by the entire moving device 7 is that when the transformer body 2 is transported and adjusted in position, the connecting plates 71 at the bottom ends of both sides of the support seat 1 can be used for assistance. By rotating the driving rod 73 on the surface of the connecting plate 71, the driving rod 73 drives the moving blocks 76 on both sides of the connecting plate 71 to slide, and at the same time, the driving rod 73 drives the lifting and lowering adjustment of the position of the bottom pulley frame 79, thereby effectively supporting the support rod 74 on the lower surface of the moving block 76 and allowing the pulley frame 79 at the bottom end of the driving rod 73 to slide.

[0049] like Figure 8 and Fig. 9 As shown, the auxiliary device 8 includes a limit plate 81, the cross-section of the limit plate 81 is "U"-shaped, the two ends of the limit plate 81 are fixedly connected to the surface of the fixed frame 3, a connecting hole 86 is opened on the surface of the limit plate 81, and the inner wall of the connecting hole 86 is movably connected with an extrusion shaft 88, the cross-section of the extrusion shaft 88 is "T"-shaped, the upper end surface of the extrusion shaft 88 is threadedly connected with a connecting plate 82, the cross-section of the connecting plate 82 is "L"-shaped, the short arm end surface of the connecting plate 82 is rotatably connected with a fixing ring 83, the arc surface of the extrusion shaft 88 is sleeved with a moving frame 85, both side surfaces of the limit plate 81 are opened with moving grooves 87, the inner wall of the moving groove 87 is slidably connected to the two ends of the moving frame 85, the cross-section of the connecting hole 86 is vertical, and the cross-sectional size of the connecting hole 86 is adapted to the cross-sectional size of the extrusion shaft 88, the long arm end surface of the connecting plate 82 is fixedly connected with an auxiliary plate 84, and the cross-sectional shape of the auxiliary plate 84 is barbed.

[0050] The effect achieved by the entire auxiliary device 8 is to effectively adjust and limit the limit plates 81 and the connecting plates 82 on the four corner surfaces of the fixing frame 3, and use the connecting holes 86 opened on the surface of the limit plates 81 to allow the extrusion shaft 88 and the connecting holes 86 to be movable, and then threadedly connected with the connecting plate 82, so that the positions of the entire connecting plate 82 and the fixing ring 83 can be moved and limited, which is convenient for position adjustment of the entire connecting plate 82 and the fixing ring 83, thereby performing hoisting and assembly operations on the transformer body 2.

[0051] The overall working principle is that when the dry-type transformer is used, a large amount of heat will be generated. At this time, it is necessary to use a spiral heat dissipation pipe to assist in the heat dissipation operation. After long-term use, the heat dissipation pipe main body 9 will be aged and damaged. At this time, the entire heat dissipation pipe main body 9 needs to be replaced and maintained and limited. Then, the slide plate 602 at the bottom of the mounting frame 5 is plugged into the slide rail 601 on the surface of the support seat 1, and the rack 603 and the gear 604 at the bottom of the mounting frame 5 are allowed to slide relative to each other. In this process, the rotating plate 609 in the side wall connecting frame 607 of the mounting frame 5 is rotated, and the rotating plate 609 is plugged into the positioning column 605 fixed on the side wall of the support seat 1. At this time, the rotating plate 609 will abut against the positioning ring 606 on the surface of the positioning column 605, and then the positioning shaft 610 on the arc surface of the positioning column 605 is squeezed and limited. At this time, the position of the entire mounting frame 5 will be fixed and cannot be moved and adjusted, so that the entire heat dissipation pipe main body 9 can be effectively and conveniently replaced, which is convenient for the long-term use of the entire dry-type transformer for heat dissipation.

[0052] In the process of transporting and moving the transformer main body 2, in order to facilitate the movement and limiting of the transformer main body 2, the driving rod 73 on the surface of the connecting plate 71 on the lower surface of the rotating support seat 1 is driven to drive the rotation and lifting of the arc surface driving frame 78 at the bottom end. At the same time, the pulley frame 79 at the bottom end of the driving rod 73 will move, and then the rotating rods 77 rotating at both ends of the driving frame 78 will drive the sliding moving blocks 76 on both sides of the connecting plate 71 to shrink, so that the support rod 74 on the lower surface of the entire moving block 76 can rise. At this time, a height difference will be formed between the pulley frame 79 and the support rod 74. At this time, the pulley frame 79 will be able to drive the entire support seat 1 to move its position, thereby conveniently and effectively moving the position of the entire transformer main body 2.

[0053] During the operation and use of the entire dry-type power transformer, in order to facilitate the hoisting and installation of the dry-type power transformer, the connecting plate 82 and the fixing ring 83 installed on the surface of the fixing frame 3 can be used for hoisting limit protection, and at the same time, the position of the limiting plate 81 on the surface of the fixing frame 3 and the connecting plate 82 and the fixing ring 83 can be moved and adjusted, and then the extrusion shaft 88 is rotated to limit the position of the connecting plate 82, thereby effectively and conveniently limiting the fixing ring 83 on the surface of the entire fixing frame 3, and facilitating the adjustment and installation of the position of the entire transformer body 2.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
