Description

Technical Field

[0001] This invention relates to the field of high-voltage transmission line fittings technology, and in particular to a conductor spacer. Background Technology

[0002] Spacer bars are protective hardware used in power engineering to fix the spacing of split conductors. They prevent conductor whipping by limiting the relative movement of sub-conductors and suppress aerodynamic vibrations and secondary span oscillations. In particular, the split conductors of high-voltage transmission lines need to be fixed in spacing by spacer bars to ensure the stable operation of the transmission system.

[0003] Existing conductor spacers are mostly integral fixed bolt connection structures. In practical applications, installation relies on special tools such as wrenches and screwdrivers. The high-altitude operation is cumbersome, time-consuming, and has low construction efficiency. Moreover, long-term high-altitude operation poses great safety hazards. The conductor clamping part is a hard metal contact, which can easily wear down the conductor insulation layer and core due to long-term friction. Summary of the Invention

[0004] The purpose of this invention is to provide a conductor spacer that can quickly clamp conductors, is easy to install, and at the same time buffers and protects conductors, extending the service life of transmission conductors and spacers, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A conductor spacer includes a frame made of high-strength, lightweight aluminum alloy, which features high strength, corrosion resistance, and light weight. The frame is uniformly provided with clamp assemblies for quickly clamping conductors. The clamp assemblies are used to quickly clamp and fix each transmission conductor one-to-one, achieving a regular arrangement of multiple conductors with equal spacing. The clamp assemblies are assembled on the periphery of the frame by hexagonal bolts, nuts, and washers. The ends of the clamp assemblies are provided with cross shafts and rubber posts. The rubber posts are distributed at the cross opening of the cross shaft. The end of the hexagonal bolt passes through the center of the cross shaft and the frame and is locked with a nut.

[0007] Preferably, the inner end face of the frame is provided with outwardly protruding limiting protrusions, the limiting protrusions are evenly distributed on the frame, and the limiting protrusions are provided with inwardly recessed limiting grooves.

[0008] Preferably, the end of the wire clamp assembly is provided with a positioning rod. The wire clamp assembly is mounted on the frame and the positioning rod is inserted into the limiting groove. During the assembly of the wire clamp assembly, the positioning rod is accurately inserted into the limiting groove. Through the cooperation between the limiting groove and the positioning rod, the pre-positioning installation of the wire clamp assembly can be realized, effectively preventing the wire clamp assembly from shifting or rotating during the assembly process, reducing the assembly difficulty and improving the assembly efficiency.

[0009] The groove length of the limiting groove is greater than the port length of the positioning rod, leaving a reasonable assembly gap. On the one hand, it can accommodate minor assembly errors during the installation process and facilitate alignment and insertion. On the other hand, it can provide a small amount of adaptive adjustment space for the wire clamp assembly when the wire swings slightly, avoiding structural jamming and improving the overall adaptability and vibration resistance of the structure.

[0010] Preferably, the wire clamp assembly includes a wire clamp body and a wire clamp cover plate. The wire clamp cover plate is connected to the wire clamp body via a hinge pin. The wire clamp body is installed on the periphery of the frame. One end of the hinge pin is connected to the wire clamp body and the other end of the hinge pin is connected to the wire clamp cover plate.

[0011] Preferably, one end of the clamp cover plate is connected to the clamp body via a hinge pin, and the other end of the clamp cover plate is connected to the clamp body via a stop pin. The end of the stop pin passes through the clamp cover plate and the clamp body, and the end of the stop pin is locked by a closed pin. The closed pin provides axial limiting and locking of the stop pin, which can completely prevent the stop pin from slipping or shifting due to vibration and wind during long-term operation of the transmission line. This eliminates the safety hazards of the clamp cover plate loosening and the conductor falling off, and greatly improves the safety and stability of the equipment operation.

[0012] Preferably, both the clamp body and the clamp cover plate are provided with arc-shaped clamping grooves for clamping the conductor. A rubber tile is provided in the arc-shaped clamping groove, and the rubber tile is in contact with the surface of the conductor. The rubber tile is made of weather-resistant rubber material with high wear resistance and high insulation. On the one hand, it can increase the friction coefficient between the clamp assembly and the conductor, improve the clamping force, and prevent the conductor from slipping. On the other hand, it can isolate the rigid contact between the clamp assembly and the conductor, avoid metal wear on the conductor insulation layer and conductor body, and further absorb the conductor vibration energy, playing a role in buffering and shock absorption, protecting the conductor, and effectively extending the service life of the transmission conductor and the spacer.

[0013] Preferably, the clamp body is provided with a first end plate, and the clamp cover is provided with a second end plate and a third end plate. The first end plate, the second end plate and the third end plate are all provided with mounting holes for installing the stop pin. The clamp cover is connected to the clamp body by the stop pin, and the second end plate and the third end plate are distributed on both sides of the first end plate.

[0014] Preferably, the end of the stop pin is provided with a locking hole for inserting a closing pin, wherein the closing pin is inserted into the locking hole to limit the stop pin.

[0015] Preferably, the closed pin includes an arc-shaped portion, a first extension portion, and a second extension portion. One end of the arc-shaped portion is integrally connected to the first extension portion, and the other end of the arc-shaped portion is integrally connected to the second extension portion. The first extension portion and the second extension portion are inserted into the locking hole provided at the end of the stop pin, and the arc-shaped portion is engaged with the stop pin.

[0016] Preferably, the frame and wire clamp assembly are made of aluminum alloy using a solid-state forging process, and the middle part of the frame has a hollow structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention places the frame at the assembly station, inserts the positioning rods at the ends of each clamp assembly into the limiting grooves on the limiting protrusions to achieve pre-positioning; inserts hexagonal bolts through the center of the cross shaft and the frame assembly hole, and initially locks them with nuts; flips the clamp cover plate open, places the transmission conductors on the rubber mat of the clamp body, closes the clamp cover plate, inserts the stop pin and assembles the closing pin to complete the locking; repeats this process until all multiple conductors are clamped and fixed. When the equipment is running, the evenly distributed clamp assemblies fix the spacing between multiple conductors, and the multiple buffer structures of the cross shaft, rubber columns and rubber mats resist the impact of conductor vibration and wind swaying. Combined with the limiting and locking structures, it ensures the long-term stable operation of the spacer bar and is suitable for various transmission line operating conditions.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To address the problems of cumbersome installation and easy damage to conductors caused by existing spacer bars, this embodiment provides the following technical solution: a conductor spacer bar, mainly used in high-voltage and ultra-high-voltage transmission lines, is used to fix the spacing between multiple split conductors, which can effectively suppress conductor vibration due to wind and secondary span oscillation, avoid collisions and friction between conductors, and ensure the operational stability of the transmission line.

[0032] Please see Figure 1 The conductor spacer includes a frame 1, which serves as the overall load-bearing base. It is made of high-strength, lightweight aluminum alloy, which features high strength, corrosion resistance, and light weight. It can withstand harsh outdoor environments such as sun exposure, rain, and frost for a long time and is not easily deformed or aged.

[0033] The frame 1 is uniformly equipped with several wire clamp assemblies 2 for quickly clamping wires.

[0034] It should be noted that the number of wire clamp components 2 can be set according to the number of split conductors of the transmission line. In this embodiment, four sets of uniformly arranged methods are used to quickly clamp and fix each transmission conductor one-to-one, so as to realize the regular arrangement of multiple conductors with equal spacing.

[0035] The clamp assembly 2 is assembled on the periphery of the frame 1 by hexagonal bolts 3, nuts 4 and washers. The washers adopt a combination structure of flat washers and spring washers, which can effectively disperse the locking pressure of hexagonal bolts 3, and at the same time prevent hexagonal bolts 3 from loosening and falling off during equipment operation, thereby improving the overall assembly firmness.

[0036] Please see Figure 3 and Figure 9 The clamp assembly 2 is provided with a cross shaft 5 and rubber posts 6 at the inner end near the frame 1. The rubber posts 6 are evenly distributed at the four interface positions of the cross shaft 5. The rubber posts 6 are made of highly elastic and aging-resistant rubber material, which has excellent buffering, shock absorption and noise reduction effects. When the transmission line vibrates or swings slightly, the rubber posts 6 can absorb the vibration energy through their own elastic deformation, weaken the force of the conductor vibration transmitted to the frame 1, avoid the overall resonance damage of the spacer, and reduce the rigid friction wear between the conductor and the spacer.

[0037] It should be noted that the end of the hex bolt 3 passes through the central through hole of the cross shaft 5 and the pre-set assembly hole of the frame 1 from top to bottom, and is finally locked and fixed by the nut 4. The center of the cross shaft 5 is precisely aligned with the assembly hole on the frame 1, which can ensure that the force on the wire clamp assembly 2 is uniform after assembly, and there will be no eccentric force or tilting offset, which greatly improves the assembly stability and structural symmetry.

[0038] Please see Figure 2 The inner end face of the frame 1 is integrally formed with an outwardly protruding limiting protrusion 11. The limiting protrusion 11 is evenly distributed at equal intervals along the circumference of the frame 1. The limiting protrusion 11 and the frame 1 are integrally cast structures with high structural strength and are not easy to break or deform.

[0039] Each limiting protrusion 11 has an inwardly recessed limiting groove 12 on its inner side. The limiting groove 12 adopts an arc-shaped groove structure and is mainly used to accurately limit and position the wire clamp assembly 2, and limit the circumferential offset and radial sway of the wire clamp assembly 2.

[0040] Specifically, a cylindrical positioning rod 7 is provided at the end of the wire clamp assembly 2 near the frame 1. During the assembly of the wire clamp assembly 2, the positioning rod 7 is precisely inserted into the limiting groove 12. Through the cooperation between the limiting groove 12 and the positioning rod 7, the wire clamp assembly 2 can be pre-positioned and installed, effectively preventing the wire clamp assembly 2 from shifting or rotating during the assembly process, which can reduce the assembly difficulty and improve the assembly efficiency.

[0041] Meanwhile, the groove length of the limiting groove 12 is greater than the port length of the positioning rod 7, leaving a reasonable assembly gap. On the one hand, it can accommodate the small assembly errors during the installation process and facilitate alignment and insertion. On the other hand, it can provide a small amount of adaptive adjustment space for the wire clamp assembly 2 when the wire swings slightly, avoiding structural jamming and improving the overall adaptability and vibration resistance of the structure.

[0042] Please see Figure 3-4The wire clamp assembly 2 includes a wire clamp body 21 and a wire clamp cover plate 22 that cooperate with each other. The wire clamp body 21 is a fixed base structure that is stably installed on the outer assembly position of the frame 1. The wire clamp cover plate 22 is hinged to the wire clamp body 21 through a hinge pin 23 to realize an open and close structure design. One end of the hinge pin 23 is inserted into the pin hole of the wire clamp body 21, and the other end is rotated and assembled into the corresponding pin hole of the wire clamp cover plate 22, so that the wire clamp cover plate 22 can be flexibly flipped open and closed around the hinge pin 23. This open and close structure can realize the quick clamping and disassembly of the wire without completely disassembling the parts. Compared with the traditional integrated wire clamp structure, the assembly and maintenance operations are more convenient and efficient, and the construction and maintenance costs of the line are greatly reduced.

[0043] To further ensure the clamping stability of the clamp assembly 2, the end of the clamp cover plate 22 away from the hinge pin 23 is detachably connected to the clamp body 21 via a stop pin 24. The stop pin 24 passes laterally through the alignment holes of the clamp cover plate 22 and the clamp body 21, thereby achieving the closing and locking of the clamp cover plate 22. At the same time, a locking hole is provided at the extended end of the stop pin 24, and a closing pin 25 is inserted into the locking hole. The closing pin 25 provides axial limiting and locking of the stop pin 24, which can completely prevent the stop pin 24 from slipping or shifting due to vibration and wind during long-term operation of the transmission line. This eliminates the safety hazards of the clamp cover plate 22 loosening and the conductor falling off, and greatly improves the safety and stability of the equipment operation.

[0044] Both the clamp body 21 and the clamp cover plate 22 have arc-shaped clamping grooves on their inner sides. The two sets of arc-shaped clamping grooves cooperate to form a complete circular clamping channel, which matches the outer diameter of the power transmission conductor. This allows for all-round fitting and wrapping of the conductor's outer wall, ensuring uniform clamping force and avoiding local stress concentration that could damage the conductor.

[0045] Rubber tiles 26 are fitted and fixed inside the arc-shaped clamping grooves. The rubber tiles 26 are made of weather-resistant rubber with high wear resistance and high insulation. On the one hand, they can increase the friction coefficient between the wire clamp assembly 2 and the conductor, improve the clamping force, and prevent the conductor from slipping. On the other hand, they can isolate the rigid contact between the wire clamp assembly 2 and the conductor, avoid metal wear on the conductor insulation layer and conductor body, and further absorb the conductor vibration energy, playing a role in buffering and shock absorption, protecting the conductor, and effectively extending the service life of the transmission conductor and the spacer.

[0046] Please see Figure 5-8 The clamp body 21 is provided with a first end plate 211, and the clamp cover plate 22 is provided with a second end plate 221 and a third end plate 222. The first end plate 211, the second end plate 221 and the third end plate 222 are all provided with mounting holes for the installation of the stop pin 24. The clamp cover plate 22 is connected to the clamp body 21 through the stop pin 24, and the second end plate 221 and the third end plate 222 are distributed on both sides of the first end plate 211.

[0047] Please see Figure 10 The closed pin 25 includes an arc-shaped portion 251, a first extension portion 252, and a second extension portion 253. One end of the arc-shaped portion 251 is integrally connected to the first extension portion 252, and the other end of the arc-shaped portion 251 is integrally connected to the second extension portion 253. The first extension portion 252 and the second extension portion 253 are inserted into the through hole at the end of the stop pin 24, and the arc-shaped portion 251 is engaged with the stop pin 24. The closed pin 25 provides axial limiting and locking for the stop pin 24, which can completely prevent the stop pin 24 from slipping or shifting due to vibration and wind during long-term operation of the transmission line. It also eliminates the safety hazards of the line clamp cover plate 22 loosening and the conductor falling off, and greatly improves the safety and stability of the equipment operation.

After the vibration stabilizes, the load is released, and the spacer bar and conductor system begin to perform free decay vibration. The continuous waveform of free decay is recorded using an intelligent signal acquisition and processing system until the amplitude decreases to 50% of the conductor diameter.

When the equipment is running, the spacing between multiple conductors is fixed by the evenly distributed clamp assemblies 2.

With the help of the limiting structure and locking structure, the spacer ensures long-term stable operation and is suitable for various transmission line conditions.
