Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment: Please refer to Figures 1-4 , the present utility model provides a technical solution: a voltage transformer with high stability, mainly aiming at the problem that in the current installation and use process of voltage transformers, due to the relatively fragile structure of the transformers, when the voltage transformers are subjected to huge pressure, the structure is often unstable, affecting the service life of the voltage transformers. The specific solution is as follows: It includes a mounting structure 1 and a current transformer body 2. The current transformer body 2 is fixedly installed on the mounting structure 1. The left and right sides of the mounting structure 1 are movably connected with a protection component 3; the protection component 3 can protect the current transformer body 2, avoiding damage to the voltage transformer caused by external pressure, which affects the service life of the voltage transformer.
[0025] Please refer to Figure 3 , wherein, the protection component 3 includes a first slide bar 31 and a second slide bar 32. The upper parts of the second slide bar 32 and the first slide bar 31 are respectively fixedly installed with a second protection bar 33 and a first protection bar 34. The second protection bar 33 and the first protection bar 34 are perpendicular to the corresponding second slide bar 32 and first slide bar 31. The second protection bar 33 and the first protection bar 34 straddle on adjacent mounting plates 11. Through the arrangement of the second protection bar 33 and the first protection bar 34, the positions on the left and right sides of the voltage transformer can be restricted, which can support the transformer while protecting the two sides of the voltage transformer, avoiding damage to the voltage transformer caused by pressure.
[0026] Further, nylon limit blocks 35 are symmetrically arranged on the opposite faces of the second protective rod 33 and the first protective rod 34. Arc-shaped inclined surfaces are provided on the opposite faces of the symmetric nylon limit blocks 35, and the arc-shaped inclined surfaces are in contact with the transformer body 2. The nylon limit blocks 35 are fixedly installed on the corresponding second protective rod 33 and the first protective rod 34 by screws. By providing the nylon limit blocks 35 made of nylon, the damage to the outer shell of the voltage transformer can be avoided during the process of fixing the transformer, and the nylon limit blocks 35 are easy to be processed according to needs, which can effectively limit the voltage transformer.
[0027] It is worth noting that, among them, the second slide rod 32 and the first slide rod 31 are respectively rotatably connected with a second screw rod 37 and a first screw rod 38 on their opposite faces. An adjusting screw sleeve 36 is arranged between the first screw rod 38 and the second screw rod 37, and the adjusting screw sleeve 36 is threadedly connected with the first screw rod 38 and the second screw rod 37; the adjusting screw sleeve 36 and the first screw rod 38 and the second screw rod 37 are all arranged outside the adjacent mounting plates 11. Through the threaded connection of the adjusting screw sleeve 36 with the first screw rod 38 and the second screw rod 37, after rotating the adjusting screw sleeve 36, the first screw rod 38 and the second screw rod 37 can move in the same or opposite directions; thus, the distance between the second protective rod 33 and the first protective rod 34 can be adjusted in real time according to different models of voltage transformers, thereby improving the fixing effect of the protective component 3 on the voltage transformer.
[0028] In this embodiment, the mounting structure 1 includes mounting plates 11 arranged on the front and back sides. The first slide rod 31 and the second slide rod 32 pass through the corresponding mounting plates 11, and the transformer body 2 is arranged between the first slide rod 31 and the second slide rod 32. Chutes for the first slide rod 31 and the second slide rod 32 to slide are provided on both sides of the mounting plate 11. By making the first slide rod 31 and the second slide rod 32 slidably connected to the mounting plate 11, the mounting plate 11 can play a guiding role in the sliding of the first slide rod 31 and the second slide rod 32.
[0029] Further, a limiting angle iron 21 is fixedly installed in the middle of the mounting plate 11. The limiting angle iron 21 is arranged between the second protective rod 33 and the first protective rod 34, and the transformer body 2 is arranged between the adjacent limiting angle iron 21. The limiting angle iron 21 is welded at the corresponding position of the mounting plate 11. By providing the limiting angle iron 21, the front and back positions of the voltage transformer can be limited, so as to cooperate with the second protective rod 33 and the first protective rod 34 to play a role in stably fixing the voltage transformer, and the second protective rod 33 and the first protective rod 34 can improve the compressive performance of the voltage transformer, further ensuring the use stability of the voltage transformer.
[0030] Working principle: For this kind of voltage transformer with high stability, by setting a protection component 3 on the installation structure 1, during the use of the voltage transformer, the compressive performance of the voltage transformer can be improved through the combined use of the protection rods II 33 and protection rods I 34 on the left and right sides and the limiting angle irons 21 on the front and back sides, further ensuring the use stability of the voltage transformer. At the same time, after rotating the adjusting sleeve 36, the first screw 38 and the second screw 37 can move in the same or opposite directions. Thus, the distance between the protection rod II 33 and the protection rod I 34 can be adjusted in real time according to different models of voltage transformers. By making the protection rod II 33 and the protection rod I 34 move towards each other, the symmetrically arranged nylon limiting blocks 35 are driven to fit the two sides of the voltage transformer, quickly restricting the position of the voltage transformer. The entire fixing process does not require any screw assistance, which is easy for the installation operation of the transformer, and the entire protection component 3 has a simple structure and is suitable for popularization and use.
