Description

Technical Field

[0001] This utility model relates to the field of surge arresters, and in particular to an insulating snap-on quick-install surge arrester. Background Technology

[0002] Surge arresters are indispensable and important protective devices in power systems, mainly used to protect electrical equipment from damage caused by lightning overvoltages and switching overvoltages. They safely conduct the large current generated by overvoltages to the ground, thereby preventing damage to critical equipment such as transformers and circuit breakers due to overvoltages and ensuring the stable operation of the power system.

[0003] In practical applications, surge arresters typically need to be installed on specific insulating supports to achieve insulation isolation and fixed support from other equipment. Traditional surge arrester installation methods often employ bolt-fixed structures, tightly connecting the surge arrester to the insulating support using bolts and nuts. While this method ensures connection stability, the installation process requires operators to repeatedly tighten the bolts and nuts using specialized tools such as wrenches, which is not only cumbersome but also consumes significant time and manpower. Especially in high-altitude or field work environments, the inconvenience of carrying and operating tools further reduces installation efficiency and increases operational risks. Therefore, this application proposes an insulating snap-on quick-installation surge arrester to address the aforementioned problems. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 - Figure 4As shown, an insulating snap-on quick-installation surge arrester includes a surge arrester body 1. An insulating connecting frame 2 is fixedly sleeved on the surge arrester body 1. The insulating connecting frame 2 is composed of an insulating base plate 6, a square insert rod 10, and a cylinder 11. The square insert rod 10 is fixedly installed at the lower end of the insulating base plate 6, and the cylinder 11 is fixedly installed at the lower end of the square insert rod 10. An insulating limiting component 3 is installed on the insulating connecting frame 2. The insulating limiting component 3 consists of an L-shaped insulating plate 12, a bottom support plate 13, a connecting block 15, and a metal elastic snap 16. The system comprises connecting square rods 17, spring pressure plates 18, and limiting springs 19. An L-shaped insulating plate 12 is fixedly installed on the outer wall of the bottom support plate 13. A connecting block 15 is fixedly installed inside the bottom support plate 13. A metal elastic buckle 16 is fixedly installed at one end of the connecting block 15. Two connecting square rods 17 are symmetrically fixedly installed on the upper inner wall of the L-shaped insulating plate 12. Spring pressure plates 18 are fixedly installed at one end of the two connecting square rods 17. Two limiting springs 19 are respectively sleeved on the two connecting square rods 17. The surge arrester body 1 is mounted on the insulating support 4 via an insulating connecting frame 2 and an insulating limiting component 3. The insulating connecting frame 2, consisting of an insulating base plate 6, a square insert 10, and a cylinder 11, and the insulating limiting component 3, consisting of an L-shaped insulating plate 12, a bottom support plate 13, a connecting block 15, a metal elastic buckle 16, a connecting square rod 17, a spring pressure plate 18, and a limiting spring 19, are used to fix the surge arrester body 1 on the insulating support 4. No bolts or wrenches are required. During installation, simply insert the square insert 10 on the insulating connecting frame 2 into the mounting square hole 5 of the insulating support 4, and under the action of the limiting spring 19, the metal elastic buckle 16 will lock onto the cylinder 11. This completes the fixing of the surge arrester body 1 on the insulating support 4, greatly simplifying the operation, saving installation time, and reducing manpower consumption. Especially in high-altitude or field operations, it avoids the inconvenience of carrying and operating tools, and reduces operational risks.

[0021] Specifically, the insulating bracket 4 has a square mounting hole 5 that passes through the insulating bracket 4 vertically. The insulating base plate 6 on the insulating connecting frame 2 has a fitting hole 7. The insulating base plate 6 is fixedly fitted onto the surge arrester body 1 through the fitting hole 7. One end of the insulating base plate 6 has a receiving groove 8, and the other end of the insulating base plate 6 has two symmetrical square through holes 9, which are interconnected. The square insertion rod 10 is inserted downward into the square mounting hole 5 on the insulating bracket 4. The insulating base plate 6 is located above the insulating bracket 4, and the cylinder 11 is located below the insulating bracket 4. The connecting square rod 17 on the insulating limiting member 3 is slidably installed in the square through hole 9 at one end of the insulating base plate 6. The spring pressure plate 18 slides... The limiting spring 19 is also located in the receiving groove 8 opened at one end of the insulating substrate 6. The L-shaped insulating plate 12 on the insulating limiting member 3 is located on the outside of the insulating substrate 6. The bottom support plate 13 is located below the insulating bracket 4. The bottom support plate 13 has a receiving groove 14. The connecting block 15 is fixedly installed on the inner wall of the receiving groove 14. The metal elastic buckle 16 is located in the receiving groove 14 and is simultaneously locked on the cylinder 11. The elastic force of the limiting spring 19 is greater than the elastic force of the metal elastic buckle 16. During installation, the limiting spring 19 is compressed to store elastic potential energy. After the L-shaped insulating plate 12 is released, the elastic force of the limiting spring 19 pushes the spring pressure plate 18 to drive the connecting square rod 17 and the L-shaped insulating plate 12. The bottom support plate 13, connecting block 15, and metal elastic buckle 16 are reset. The elastic force inherent in the metal elastic buckle 16, pushed by the elastic force of the limiting spring 19, causes the metal elastic buckle 16 to deform upon contact with the cylinder 11 and smoothly slide past it. Subsequently, under its own elastic force, it resets and locks onto the cylinder 11, achieving a tight clamping. The limiting spring 19 provides a continuous reset force, ensuring that the metal elastic buckle 16 can tightly adhere to and lock onto the cylinder 11, preventing it from loosening and detaching from the cylinder 11 after installation, thus ensuring the stability of the surge arrester body 1. The function of the metal elastic buckle 16 is to lock onto the cylinder 11 through its own elastic deformation, forming a connection between the insulating connecting frame 2 and the insulating limiting member 3. Mechanical locking secures the surge arrester body 1 to the insulating bracket 4, enabling rapid installation and fixation without bolts or other tools. The limit spring 19 is made of fatigue-resistant elastic material, and its elastic deformation remains within a reasonable range during normal installation, disassembly, and use, maintaining stable elastic force for a long time to ensure continuous pressure on the metal elastic buckle 16. The metal elastic buckle 16 is made of highly elastic metal material, possessing good deformation resistance and wear resistance. During repeated engagement and disengagement with the cylinder 11, its elastic recovery performance is not easily diminished, and its service life matches that of the limit spring 19, meeting the needs of long-term installation and use of the surge arrester. The combination of the two ensures the stability of the installation structure of the surge arrester body 1 during long-term use.

[0022] When fixing the surge arrester body 1 onto the insulating bracket 4, first pull the L-shaped insulating plate 12 to cause the connecting square rod 17 to slide the spring pressure plate 18 within the square through hole 9 and the receiving groove 8. At this time, the spring pressure plate 18 will compress the limiting spring 19, and the L-shaped insulating plate 12 will move the bottom support plate 13. The bottom support plate 13 will then move the connecting block 15 and the metal elastic buckle 16 until the bottom support plate 13 is removed from under the square insert rod 10 and the cylinder 11. Then, align the square insert rod 10 on the insulating connecting frame 2 with the mounting square hole of the insulating bracket 4. Insert the cylinder 11 into the insulating bracket 4 until the insulating substrate 6 is attached to the upper surface of the insulating bracket 4. At this time, the cylinder 11 is located below the insulating bracket 4. Then, release the L-shaped insulating plate 12. At this time, the limiting spring 19 will extend and return to its original position. Under the elastic force of the limiting spring 19, the spring pressure plate 18 will be pushed to drive the connecting square rod 17, the L-shaped insulating plate 12, the bottom support plate 13, the connecting block 15, and the metal elastic buckle 16 to reset. Finally, the metal elastic buckle 16 will be locked on the cylinder 11 during the reset process. At this time, the lightning arrester body 1 is fixedly installed on the insulating bracket 4.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
