Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding arrangement equipment, in particular to a winding arrangement structure of a rectifier transformer. Background Art

[0002] In the design and application of rectifier transformers, the spacing of the winding shafts is a crucial parameter. It directly affects the arrangement of the windings, the electromagnetic coupling effect, and the rectification efficiency. Traditional rectifier transformers usually use a fixed winding shaft spacing, which means that once the transformer is manufactured, its winding arrangement and performance parameters are difficult to adjust.

[0003] However, in practical applications, fixed winding shaft spacing often cannot meet diverse needs. For example, in different working scenarios, different winding arrangements may be required to optimize electromagnetic performance or adapt to specific rectification requirements. In addition, as the power system and load change, the performance requirements for the rectifier transformer will also change. If the spacing of the winding shaft cannot be adjusted, it will be difficult to achieve the optimal design and operation of the rectifier transformer. In view of this, we propose a winding arrangement structure for the rectifier transformer. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] The winding arrangement structure of the rectifier transformer includes a symmetrically arranged bottom plate 1 and an upper plate 2 and a vertical plate 9 fixed therebetween. Two winding shafts 5 with adjustable spacing are installed on the top of the bottom plate 1 and on both sides of the vertical plate 9. A slider 60 is fixedly connected to the top and bottom of each winding shaft 5. A slide groove 6 slidably connected to the slider 60 is provided on the top of the bottom plate 1 and the bottom of the upper plate 2. Two screw rods 7 are symmetrically rotatably installed in each slide groove 6. The two screw rods 7 are respectively threadedly connected to the two sliders 60. A driving mechanism for driving the screw rod 7 to rotate is installed on both sides of the vertical plate 9. By setting two winding shafts 5 with adjustable spacing, the spacing of the winding shafts 5 can be adjusted as needed, thereby improving the flexibility and applicability of the winding arrangement of the rectifier transformer.

[0025] As a preferred embodiment of the present invention, a universal wheel 4 is fixedly mounted at each of the four corners of the bottom of the bottom plate 1. The entire winding arrangement structure can be conveniently moved and carried, thereby improving the convenience of use.

[0026] As a preferred embodiment of the present invention, the driving mechanism includes a transmission box 8 fixed in the middle of the chute 6, a first bevel gear 80 is provided inside the transmission box 8, two second bevel gears 81 are symmetrically meshed on the first bevel gear 80, a connecting shaft 82 is coaxially fixed on each second bevel gear 81, and two screw rods 7 in the same chute 6 are coaxially welded to the two connecting shafts 82. This driving mechanism can realize the synchronous rotation of the two screw rods 7, thereby driving the slider 60 to move along the chute 6.

[0027] As a preferred embodiment of the present invention, the driving mechanism further comprises two cranks 3 symmetrically connected to the upper plate 2, the two cranks 3 are respectively located on both sides of the vertical plate 9, and the transmission shaft 30 of the crank 3 and the two first bevel gears 80 located on the same straight line are coaxially fixed. By rotating the crank 3, the transmission shaft 30 can be driven to rotate, thereby driving the first bevel gear 80 and the second bevel gear 81 to rotate, thereby realizing the rotation of the screw rod 7 and the movement of the slider 60. This operation method is simple and convenient and easy to implement.

[0028] As a preferred embodiment of the present invention, the transmission shaft 30 passes through the outer wall of the transmission box 8 and is rotatably connected thereto through a bearing, thereby ensuring stable rotation of the transmission shaft 30, and the distance between the two connecting shafts 82 in the same transmission box 8 is greater than the diameter of the transmission shaft 30. Interference between the transmission shaft 30 and the connecting shaft 82 is avoided.

[0029] As a preferred embodiment of the present invention, a threaded hole 601 is provided on the slider 60 to be threadedly connected to the screw rod 7, and the thread lines of the two screw rods 7 in the same slide 6 are in the same direction. The two second bevel gears 81 rotate in opposite directions, while the screw rods 7 have the same thread direction, so that the two sliders 60 in the same slide 6 can move toward or away from each other.

[0030] As a preferred embodiment of the present invention, two limiting bars 600 are symmetrically formed on the slider 60, and a limiting groove 61 is provided on the inner wall of the slide 6 to be slidably connected to the limiting bars 600, thereby ensuring the stable movement of the slider 60 and the accuracy of the spacing adjustment of the winding shaft 5.

[0031] When the winding arrangement structure of the rectifier transformer of the present invention is used, when it is necessary to adjust the arrangement spacing of the windings of the rectifier transformer, the operator first determines the required spacing size. Then, they start the adjustment process by manually turning the cranks 3 located on both sides of the vertical plate 9. Each crank 3 is coaxially fixed to two first bevel gears 80 located on the same straight line through its transmission shaft 30.

[0032] When the crank 3 rotates, the transmission shaft 30 rotates accordingly, thereby driving the first bevel gear 80 to rotate. The first bevel gear 80 is meshed with the two second bevel gears 81, so the rotation of the first bevel gear 80 will simultaneously drive the two second bevel gears 81 to rotate. Each second bevel gear 81 is coaxially fixed with a connecting shaft 82, and the connecting shaft 82 is coaxially welded with the screw rod 7 in the slide groove 6. Therefore, the rotation of the second bevel gear 81 is transmitted to the screw rod 7, causing it to start rotating.

[0033] The rotation of the screw rod 7 drives the slider 60 threadably connected thereto to move along the slide groove 6. Since the thread lines of the two screw rods 7 in the same slide groove 6 are in the same direction, when the screw rod 7 rotates, the two sliders 60 will move in the same direction at the same time, and the moving distance will remain the same. In this way, the winding shafts 5 fixed on the sliders 60 will also move accordingly, thereby changing the distance between the winding shafts 5.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
