Abstract
Description
Technical Field
[0001] This utility model relates to a high-altitude long-life transformer. Background Technology
[0002] High-altitude long-life transformers are power transformers specifically designed for operation in harsh environments, primarily used for power transmission and distribution in high-altitude areas. The core components of a high-altitude long-life transformer include an iron core, coils surrounding the iron core, an upper support frame at the top of the iron core, an external plate connected to the coil leads, high-voltage insulators, and a high-voltage terminal assembly for connecting and fixing the external plate. Existing high-altitude transformers are frequently subjected to external vibrations or impacts, leading to loosening or displacement of the high-voltage terminal assembly during long-term use. This results in an unstable connection between the external plate and the high-voltage terminals, which can seriously affect the normal operation of the transformer, leading to a decrease in its long-term stability and service life. Improvements and optimizations are proposed to address this issue. Utility Model Content
[0003] To address the above problems, the technical problem to be solved by this utility model is to provide a high-altitude, long-life transformer.
[0004] The technical solution adopted by this utility model of a high-altitude long-life transformer includes: an iron core, a coil sleeved outside the iron core, an upper support frame located at the upper end of the iron core, an outer connecting plate connected to the lead-out end of the coil, a high-voltage insulator, and a high-voltage terminal assembly for connecting and fixing the outer connecting plate. The high-voltage terminal assembly includes screws, an impact adjusting plate, an energy storage spring, an inner nut, and an outer nut. The upper support frame includes a support frame body, the upper and lower ends of which are vertically bent to form an upper support frame and a lower support frame, respectively. The upper support frame is vertically bent inward to form spaced-apart support frame connecting plates. The connecting plates are provided with connecting plate through holes and... The docking plate adjustment port is located at the left and right ends of the docking plate through hole. The side wall of the docking plate adjustment port is provided with adjustment teeth. The impact adjustment plate includes an adjustment plate body and adjustment plate side parts located at both ends of the adjustment plate body and passing through the docking plate adjustment port. The adjustment plate side parts are provided with anti-reverse grooves that are spaced apart and correspond to the adjustment teeth. The adjustment plate body is provided with an adjustment plate through hole. The screw passes through the adjustment plate through hole, the energy storage spring, the docking plate through hole, and the high voltage insulator in sequence, and is first threadedly connected to the inner nut, and then passes through the outer plate and is threadedly connected to the outer nut.
[0005] The high-voltage terminal assembly also includes an anti-rotation sleeve and a reinforcing nut. The anti-rotation sleeve is provided with a nut limiting groove for preventing the outer nut from rotating, and the nut limiting groove is provided with an anti-rotation sleeve through hole for the screw to pass through.
[0006] The upper and lower ends of the main body of the adjustment plate are vertically bent to form adjustment plate stops for limiting the energy storage spring.
[0007] The adjusting plate has adjusting teeth on its outer side wall and anti-reverse groove on its side side wall.
[0008] The lower part of the support frame has a relief opening at the joint plate with the support frame to facilitate the installation and removal of the screws.
[0009] The advantages of this high-altitude long-life transformer are as follows: It introduces an impact adjustment plate and an energy storage spring. The anti-retraction groove on the side of the adjustment plate interacts with the adjustment teeth on the adjustment port of the docking plate, which can convert the external impact force into a controllable lateral displacement of the impact adjustment plate. Then, the energy storage spring provides a stable horizontal compressive force to the screw, further mitigating the impact force on the screw, thereby effectively reducing loosening caused by vibration or impact, and improving the operational reliability and service life of the equipment.

[0017] like Figure 1-6As shown, the high-altitude long-life transformer of this utility model includes an iron core 1, a coil 2 sleeved on the iron core 1, an upper support frame 3 located on the upper end of the iron core 1, an outer plate 4 connected to the lead-out end of the coil 2, a high-voltage insulator 5, and a high-voltage terminal assembly 6 for connecting and fixing the outer plate 4. The high-voltage terminal assembly 6 includes screws 9, impact adjustment plates 10, energy storage springs 11, inner nuts 12, and outer nuts 13. The upper support frame 3 includes a support frame body 18. The upper and lower ends of the support frame body 18 are vertically bent to form an upper support frame 19 and a lower support frame 20, respectively. The upper support frame 19 is vertically bent inward to form spaced support frame docking plates 21. The support frame docking plates 21 are provided with docking plate through holes 22 and docking plate adjustment ports 23 located at the left and right ends of the docking plate through holes 22. The side walls of the docking plate adjustment ports 23 are provided with adjustment teeth 24. The impact adjustment plate 10 includes an adjustment plate body 28 and a set at both ends of the adjustment plate body 28. An adjustment plate side portion 29 is provided on the adjustment port 23 of the docking plate. The adjustment plate side portion 29 is provided with anti-retraction grooves 30 that are spaced apart and correspond to the adjustment teeth 24. The adjustment plate body 28 is provided with an adjustment plate through hole 31. The screw 9 passes through the adjustment plate through hole 31, the energy storage spring 11, the docking plate through hole 22, and the high-voltage insulator 5 in sequence. It is first threadedly connected to the inner nut 12, and then passes through the outer plate 4 and is threadedly connected to the outer nut 13. An impact adjustment plate 10 and an energy storage spring 11 are introduced. The anti-retraction grooves 30 of the adjustment plate side portion 29 interact with the adjustment teeth 24 on the docking plate adjustment port 23. The external impact force can be converted into a controllable lateral displacement of the impact adjustment plate 10. The energy storage spring 11 provides a stable horizontal compressive force to the screw 9. The impact force or vibration energy will not be directly transmitted to the connection between the screw 9 and the outer plate 4, thereby effectively reducing loosening caused by vibration or impact and improving the operational reliability and service life of the equipment.
[0018] The high-voltage terminal assembly 6 also includes an anti-rotation sleeve 14 and a reinforcing nut 15. The anti-rotation sleeve 14 is provided with a nut limiting groove 34 for limiting the rotation of the outer nut 13. The nut limiting groove 34 is provided with an anti-rotation sleeve through hole 33 for the screw 9 to pass through, so as to prevent the outer nut 13 from loosening or rotating due to vibration or long-term operation.
[0019] The upper and lower ends of the adjustment plate body 28 are vertically bent to form adjustment plate stops 36 for limiting the position of the energy storage spring 11, effectively limiting the position of the energy storage spring 11 and preventing the energy storage spring 11 from shifting or failing during vibration.
[0020] The outer wall of the adjustment port 23 of the docking plate is provided with the adjustment teeth 24, and the outer wall of the side portion 29 of the adjustment plate is provided with the anti-reverse groove 30, so that the force is more balanced and the movement is more stable and smooth.
[0021] The lower part 20 of the support frame is provided with a support frame clearance opening 38 at the docking plate 21 of the support frame to facilitate the installation and disassembly of the screw 9, which simplifies the installation and maintenance process and reduces the difficulty of operation.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
