Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to an insulator structure with a built-in condition monitoring sensor. Background Technology

[0002] Insulators are critical components in power systems used to fix conductors and ensure electrical insulation; their operating status directly affects the safety and stability of the power system. With the development of smart grids, it is necessary to monitor the operating parameters of insulators in real time to provide early warnings of potential faults.

[0003] However, the traditional insulator structure with built-in condition monitoring sensors, especially rod insulators, often integrates the condition monitoring sensors with the core rod and sheath. This means that when the built-in condition monitoring sensor fails due to long-term use, it is impossible to disassemble and maintain the sensor separately. Instead, the entire insulator must be disassembled and replaced as a whole, which increases the cost of operation and maintenance. For example, in a high-voltage transmission line, the condition monitoring sensor and the core rod are integrated by epoxy resin potting and curing. After long-term operation, the sensor's signal acquisition module experienced a data transmission interruption fault. Since the sensor and the insulator body cannot be separated, the maintenance personnel can only remove the faulty insulator from the transmission line as a whole and replace it with a brand new insulator product, resulting in a long maintenance time for each operation. Utility Model Content

[0004] This utility model discloses an insulator structure with a built-in condition monitoring sensor, aiming to solve the technical problem of traditional insulator structures with built-in condition monitoring sensors, especially rod-shaped insulators where the built-in condition monitoring sensor is often integrally formed with the core rod and sheath. This results in the inability to disassemble and maintain the sensor separately when it fails due to long-term use, requiring the entire insulator to be disassembled and replaced as a whole, which increases the maintenance cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An insulator structure with a built-in condition monitoring sensor includes a core rod, a base connected to the bottom outer wall of the core rod, and multiple equally spaced sheds connected to the outer wall of the core rod. It also includes: a quick-release mechanism comprising multiple equally spaced telescopic rods connected to the bottom inner wall of the core rod, springs connected to the outer walls of the telescopic rods, a common fixing plate connected to the top outer walls of the multiple telescopic rods, a condition monitoring sensor body connected to the top outer wall of the fixing plate, an end cap connected to the top outer wall of the core rod, and a threaded post connected to the bottom outer wall of the end cap, the threaded post being threadedly connected to the inner wall of the core rod; and a sealing mechanism located on the bottom outer wall of the end cap.

[0006] By adopting the above technical solution, the quick-release mechanism includes multiple telescopic rods evenly distributed on the inner wall of the bottom of the rod core. A fixed plate is connected to the top outer wall of these telescopic rods. The fixed plate supports the status monitoring sensor body on its top outer wall. The status monitoring sensor body is used to collect the insulator's operating status parameters in real time. When the status monitoring sensor body is installed inside the rod core, it compresses the multiple telescopic rods connected to the bottom of the fixed plate. At this time, the telescopic rods guide the movement of springs connected to their outer walls. The springs generate an upward preload through elastic deformation, thereby achieving the effect of pushing the fixed plate upward through the compressed elastic force of the multiple springs after the end cap connected to the top outer wall of the rod core is removed. This facilitates the removal of the status monitoring sensor body. The end cap is used to seal the opening at the top of the rod core, preventing external dust and moisture from entering the rod core. A threaded post is connected to the bottom outer wall of the end cap, and the threaded post is connected to the inner wall of the rod core through threaded connection. This achieves a detachable connection between the end cap and the rod core through the threaded engagement, thus facilitating quick disassembly and maintenance.

[0007] As a further embodiment of this utility model: the sealing mechanism includes a connecting groove disposed on the outer wall of the bottom of the end cap, a first sealing ring connected to one side of the outer wall of the connecting groove, a connecting ring connected to the top outer wall of the rod core, the connecting ring fitting against the bottom outer wall of the first sealing ring, and a second sealing ring connected to the end of the connecting groove away from the first sealing ring, the second sealing ring fitting against the inner wall of the connecting ring.

[0008] By adopting the above technical solution, the sealing mechanism includes a connecting groove on the outer wall of the bottom of the end cap. The connecting groove is used to accommodate the first sealing ring, the second sealing ring, and the connecting ring. The connecting groove and the connecting ring work together to form a double barrier channel. At this time, the first sealing ring fills the gap between the connecting groove and the connecting ring through elastic deformation, blocking the initial penetration of external dust and moisture. At the same time, the end of the connecting groove away from the first sealing ring is connected to the second sealing ring. The second sealing ring is attached to the inner wall of the connecting ring to form a radial seal, thereby further blocking the trace amount of medium that leaks through the first sealing ring, thereby improving the sealing effect at the connection between the rod core and the end cap.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Facilitates the disassembly and assembly of the sensor built into the rod core. During the installation of the status monitoring sensor, the spring is compressed and stored with the help of the telescopic rod. After the end cap is removed, the spring releases its elastic force to push the fixing plate and move the status monitoring sensor upward. With the threaded quick disassembly and assembly structure of the end cap and the rod core, the sensor can be easily removed and installed without complicated tools, which improves the disassembly and assembly efficiency of the sensor built into the rod core and facilitates daily maintenance and replacement.

[0010] 2. Improve the sealing effect at the end of the rod core. A double barrier channel is constructed by the connection groove and the connection ring. The first sealing ring fills the gap between the first sealing ring and the top of the connection ring to achieve the initial seal. At the same time, the second sealing ring is interference-fitted to the inner wall of the connection ring, thereby achieving the effect of blocking minor leakage. Through the double sealing protection of the first sealing ring and the second sealing ring, the intrusion of external moisture is effectively blocked, thereby improving the sealing reliability of the connection between the rod core and the end cap.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 3An insulator structure with a built-in condition monitoring sensor includes a core rod 1, a base 3 connected to the bottom outer wall of the core rod 1, and multiple equally spaced umbrella skirts 2 connected to the outer wall of the core rod 1. It also includes: a quick-release mechanism comprising multiple equally spaced telescopic rods 4 connected to the bottom inner wall of the core rod 1, springs 5 ​​connected to the outer wall of the telescopic rods 4, a common fixing plate 6 connected to the top outer wall of the multiple telescopic rods 4, a condition monitoring sensor body 7 connected to the top outer wall of the fixing plate 6, an end cap 8 connected to the top outer wall of the core rod 1, and a threaded post 9 connected to the bottom outer wall of the end cap 8, the threaded post 9 being threadedly connected to the inner wall of the core rod 1; and a sealing mechanism located on the bottom outer wall of the end cap 8.

[0019] Specifically, the quick-release mechanism includes multiple telescopic rods 4 evenly distributed at intervals connected to the inner wall of the bottom of the rod core 1. A common fixing plate 6 is connected to the top outer wall of the multiple telescopic rods 4. The fixing plate 6 supports the status monitoring sensor body 7 on its top outer wall. The status monitoring sensor body 7 is used to collect the operating status parameters of the insulator in real time. When the status monitoring sensor body 7 is installed inside the rod core 1, it compresses the multiple telescopic rods 4 connected to the bottom of the fixing plate 6. At this time, the telescopic rods 4 guide the movement of the springs 5 ​​connected to their outer walls. The springs 5 ​​generate upward preload through elastic deformation. The force is such that after the end cap 8 connected to the top outer wall of the rod core 1 is disassembled, the elastic force of the multiple springs 5 ​​after compression pushes the fixing plate 6 upward, thereby facilitating the removal of the status monitoring sensor body 7. The end cap 8 is used to seal the top opening of the rod core 1 to prevent external dust and moisture from entering the interior of the rod core 1. At this time, the bottom outer wall of the end cap 8 is connected to the threaded post 9, which is connected to the inner wall of the rod core 1 by threads. Thus, the end cap 8 and the rod core 1 are detachably connected through the threaded engagement of the two, thereby facilitating quick disassembly and maintenance.

[0020] The rod core 1 has an installation cavity on one side of its outer wall. The status monitoring sensor body 7 is installed on the inner wall of the installation cavity. The height of the status monitoring sensor body 7 is slightly less than the depth of the installation cavity. The installation cavity provides installation space for the status monitoring sensor body 7 and provides physical protection for it.

[0021] Specifically, multiple springs 5 ​​are connected to the bottom outer wall of the same fixed plate 6, and the fixed plate 6 is provided with elastic force by the multiple springs 5, thereby achieving the function of pushing out the status monitoring sensor body 7.

[0022] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, the sealing mechanism includes a connecting groove 10 disposed on the bottom outer wall of the end cap 8, a first sealing ring 11 connected to one side outer wall of the connecting groove 10, a connecting ring 13 connected to the top outer wall of the rod core 1, the connecting ring 13 fitting against the bottom outer wall of the first sealing ring 11, and a second sealing ring 12 connected to one end of the connecting groove 10 away from the first sealing ring 11, the second sealing ring 12 fitting against the inner wall of the connecting ring 13.

[0023] Specifically, the sealing mechanism includes a connecting groove 10 disposed on the outer wall of the bottom of the end cap 8. The connecting groove 10 is used to accommodate the first sealing ring 11, the second sealing ring 12, and the connecting ring 13. The connecting groove 10 and the connecting ring 13 work together to form a double barrier channel. At this time, the first sealing ring 11 fills the gap between the connecting groove 10 and the connecting ring 13 through elastic deformation, blocking the initial penetration of external dust and moisture. At the same time, the end of the connecting groove 10 away from the first sealing ring 11 is connected to the second sealing ring 12. The second sealing ring 12 fits against the inner wall of the connecting ring 13 to form a radial seal, thereby further blocking the trace amount of medium that leaks through the first sealing ring 11, thereby improving the sealing effect at the connection between the rod core 1 and the end cap 8.

[0024] The first sealing ring 11 and the second sealing ring 12 are both made of rubber. The sealing effect of the two is ensured by filling the gap at the connection between the first sealing ring 11 and the connecting groove 10 with the rubber material.

[0025] Specifically, the outer wall of the connecting ring 13 near the second sealing ring 12 is provided with a sealing groove 14, and the second sealing ring 12 is attached to the inner wall of the sealing groove 14. By attaching the outer wall of the second sealing ring 12 to the inner wall of the sealing groove 14, the sealing tightness is enhanced by the compression between the groove wall and the sealing ring.

[0026] Reference Figure 1 and Figure 2 In a preferred embodiment, the core 1, end cap 8, base 3, and multiple umbrella skirts 2 are all made of alumina ceramic.

[0027] Specifically, the rod core 1, end cap 8, base 3, and multiple skirts 2 made of alumina ceramic have good insulation properties, which can effectively block high voltage electric field leakage and ensure the electrical safety of the insulator.

[0028] Working Principle: During use, when installing the status monitoring sensor body 7, first place the sensor into the mounting cavity inside the rod core 1, thus placing it on the surface of the fixing plate 6. Then, press the status monitoring sensor body 7 into the mounting cavity of the rod core 1, causing the multiple telescopic rods 4 connected to the bottom outer wall of the fixing plate 6 to retract, and the springs 5 ​​connected to the outer walls of the telescopic rods 4 to be compressed together, thereby storing elastic potential energy. Next, the end cap 8 is threadedly connected to the rod core 1 through the threaded post 9, thereby closing the top opening of the rod core 1. At this time, the first sealing ring 11 in the sealing mechanism fills the axial gap between the connecting groove 10 and the connecting ring 13, and the second sealing ring 12 fits into the sealing groove 14 opened on the inner wall of the connecting ring 13 to form a radial seal, thus achieving a double protection effect. When it is necessary to maintain the status monitoring sensor body 7, rotate the end cap 8 in the opposite direction and remove the end cap 8 through the threaded engagement. At this time, the spring 5 releases elastic potential energy, pushing the fixing plate 6 to move the status monitoring sensor body 7 upward, and the operator can directly remove the sensor without complicated tools, thus achieving the effect of convenient maintenance.

[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
