Description

Technical Field

[0001] This utility model relates to the field of conductor technology, specifically a transposed conductor for a high-voltage reactor. Background Technology

[0002] High-voltage reactors are important reactive power compensation devices in power systems, widely used in power grid reactive power regulation, harmonic suppression, and voltage fluctuation control. With the expansion of power system scale and the increase in voltage levels, the performance requirements for high-voltage reactors are also becoming increasingly stringent, including higher capacity, efficiency, and stability. Transposed conductors are a common equipment configuration method in power engineering, typically referring to the exchange of positions between two conductors in a power transmission line to optimize line layout or reduce electromagnetic interference. Protective rings are used between transposed conductors to prevent direct contact between multiple sets of conductors. However, most protective rings within transposed conductors are integral, making timely replacement difficult when damaged. This can easily lead to wear and tear on the transposed conductors, potentially causing short circuits and reducing their service life. Utility Model Content

[0003] The purpose of this invention is to provide a transposition conductor for high-voltage reactors to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transposition conductor for a high-voltage reactor, comprising a transposition frame, a conductor connected within the transposition frame, a movable plate within the transposition frame, a first protective ring overlapping below the movable plate, a second protective ring overlapping below the first protective ring, a groove within the movable plate, a locking structure above the transposition frame, the locking structure engaging within the groove, a fixing post above the second protective ring, the engaging structure engaging with the fixing post, the engaging structure comprising a rotating rod, a limiting block, and a turntable, a connecting plate fixedly connected to the outside of the turntable, a limiting post on one side of the connecting plate, and a coil spring sleeved on the rotating rod.

[0005] As a further preferred embodiment of this technical solution, the second protective ring is sleeved on the outside of the conductor body, the first protective ring is sleeved on the outside of the conductor body, a sliding groove is provided above the transposition frame, and the moving plate is slidably connected in the sliding groove.

[0006] As a further preferred embodiment of this technical solution, the fixing post is engaged within the protective ring, the fixing post is engaged within the moving plate, the limiting block is engaged with the fixing post, and the rotating rod is rotatably connected above the moving plate.

[0007] As a further preferred embodiment of this technical solution, the turntable is fixedly connected to the outside of the rotating rod, the limiting block is slidably connected above the moving plate, and the limiting block is engaged with the fixed column.

[0008] As a further preferred embodiment of this technical solution, the connecting plate is connected to the limiting block via a limiting post, and the turntable is fixedly connected above the moving plate via a coil spring.

[0009] As a further preferred embodiment of this technical solution, the locking structure includes a bolt, which is fixedly connected to the top of the repositioning frame. The bolt is engaged in a groove, and a nut is connected to the external thread of the bolt. The nut is engaged with the moving plate.

[0010] This utility model provides a transposition conductor for high-voltage reactors, which has the following advantages:

[0011] (1) This utility model sets up a movable plate, a protective ring one, a protective ring two, and a snap-fit ​​structure. The rotating rod drives the turntable to rotate. Since the connecting plate is connected to the limiting block through the limiting post, the limiting block will slide inside the movable plate. The turntable will drive the coil spring to deform. The protective ring two is then inserted into the movable plate and the protective ring one through the fixing post. When the rotating rod is released, the limiting block will be reset by the action of the coil spring. The replacement wire, through the cooperation between the coil spring, the limiting block, and the limiting post, enables the protective ring one and the protective ring two to be quickly assembled with the movable plate. When the protective ring one or the protective ring two is damaged, it can be replaced or repaired in time, avoiding wear of the wire body inside the replacement frame, thereby ensuring the service life of the replacement wire.

[0012] (2) By setting a locking structure, the present invention drives the moving plate to slide in the groove. When the moving plate moves to the appropriate position, the first protective ring can be attached to the bottom of the moving plate, and the first and second protective rings under the moving plate can be stored in the shift frame. The nut and bolt are threaded together, and the nut will be engaged with the moving plate, thereby locking the position of the moving plate and preventing the moving plate from loosening due to external force.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown, in this embodiment, a transposition conductor for a high-voltage reactor includes a transposition frame 1, a conductor body 2 connected inside the transposition frame 1, a movable plate 3 inside the transposition frame 1, a protective ring 4 overlapping below the movable plate 3, a protective ring 5 overlapping below the protective ring 4, a groove 10 inside the movable plate 3, a locking structure 7 above the transposition frame 1, the locking structure 7 being engaged in the groove 10, a fixing post 9 above the protective ring 5, and a locking structure 6 engaging with the fixing post 9. The locking structure 6 includes a rotating rod 601, a limiting block 602, and a turntable 603. A connecting plate 604 is fixedly connected to the outside of the turntable 603, a limiting post 605 is provided on one side of the connecting plate 604, and a coil spring 606 is sleeved on the rotating rod 601.

[0021] like Figure 1 and Figure 5 As shown, the second protective ring 5 is sleeved on the outside of the conductor body 2, the first protective ring 4 is sleeved on the outside of the conductor body 2, a sliding groove 8 is provided above the transposition frame 1, the moving plate 3 is slidably connected in the sliding groove 8, the fixed post 9 is snapped in the first protective ring 4, the fixed post 9 is snapped in the moving plate 3, the limiting block 602 is snapped in the fixed post 9, the rotating rod 601 is rotatably connected above the moving plate 3, the turntable 603 is fixedly connected outside the rotating rod 601, the limiting block 602 is slidably connected above the moving plate 3, and the limiting block 602 is snapped in the fixed post 9;

[0022] By setting the slide groove 8, when a pushing or pulling force is applied to the moving plate 3, the moving plate 3 will slide in the slide groove 8, so that the slide groove 8 plays a certain guiding role in the movement of the moving plate 3, and avoids the phenomenon of the moving plate 3 shifting its position when moving.

[0023] The connecting plate 604 is connected to the limiting block 602 via the limiting post 605. The turntable 603 is fixedly connected to the upper part of the moving plate 3 via the coil spring 606. The locking structure 7 includes a bolt 701, which is fixedly connected to the upper part of the shift frame 1. The bolt 701 is engaged in the groove 10. The bolt 701 is externally threaded with a nut 702, which is engaged with the moving plate 3.

[0024] By setting a coil spring 606, the rotating rod 601 drives the turntable 603 to rotate. Since the connecting plate 604 is connected to the limiting block 602 through the limiting post 605, the limiting block 602 will slide within the moving plate 3. The turntable 603 will cause the coil spring 606 to deform, so that the coil spring 606 plays a certain auxiliary role in the rotation of the turntable 603 and prevents the turntable 603 from being misaligned during rotation.

[0025] This utility model provides a transposition conductor for high-voltage reactors, and its specific working principle is as follows:

[0026] The movable plate 3 slides within the slide groove 8. When the movable plate 3 moves to the appropriate position, the protective ring 4 can be placed under the movable plate 3, and the conductor 2 will contact the protective ring 4. The rotating rod 601 drives the turntable 603 to rotate. Since the connecting plate 604 is connected to the limiting block 602 through the limiting post 605, the limiting block 602 will slide within the movable plate 3, and the turntable 603 will cause the coil spring 606 to deform. The protective ring 5 is then inserted into the movable plate 3 and the protective ring 4 through the fixing post 9. When the rotating rod 601 is released, the limiting block 602 will be reset by the action of the coil spring 606. After being reset, the limiting block 602 will be engaged with the fixing post 9. Then, the protective ring 4 and the protective ring 5 under the movable plate 3 are stored in the shift frame 1, which drives the nut 702 to be threadedly connected to the bolt 701, and the nut 702 will be engaged with the movable plate 3.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
