Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to an overhead insulated conductor resistant to wind resistance. Background Technology

[0002] Overhead insulated conductors are widely used in power distribution networks, but their safe operation faces severe challenges in typhoon and monsoon-prone areas, as well as in strong wind zones such as canyons and coastlines. Traditional overhead insulated conductors mainly reduce wind resistance by installing smooth or grooved sheaths on the outside of the insulation layer. Their wind resistance depends on the mechanical strength of the conductor (such as steel-cored aluminum stranded wire) and the support of the towers.

[0003] Chinese Patent Publication No. CN 221406822 U discloses a utility model of an overhead insulated conductor with wind resistance, relating to the field of conductor technology. The conductor includes an insulating sleeve with multiple sets of first protrusions evenly arranged on both sides and multiple sets of second protrusions evenly arranged on the top and bottom. A filling layer is provided inside the insulating sleeve. In this utility model, when lateral airflow exerts force on the conductor, the airflow will pre-contact the first protrusions and be diverted and guided by the arc-shaped structure of the first protrusions. Direct airflow is diverted to the top and bottom of the conductor, while the remaining airflow is pre-diverted or its flow direction is changed before contacting the conductor. This reduces the impact of the airflow on the conductor, allowing the conductor itself to buffer the airflow and reduce the impact of the airflow on the connection between the overhead insulated conductor and electrical components. Simultaneously, it improves the wind resistance effect.

[0004] However, the above solution still has the following problems: The conductors of existing wires, such as steel cores and insulation layers, are fixedly bonded or extruded into one structure. Under periodic large-amplitude dancing or vibration caused by strong winds, stress is concentrated at the connection between the conductor and the clamp and the conductor itself, which can easily lead to metal fatigue and strand breakage. Moreover, the vibration will be transmitted to the insulation layer, accelerating the aging of the insulation. Conductors usually need to be connected or fixed at the end using tension clamps or splicing tubes. These connection points have complex structures and sudden changes in stiffness, which can easily form stress concentration points under wind loads, making them high-risk areas for failure. Existing connection technologies are mostly rigid or semi-rigid, lacking effective dynamic load buffering capabilities. It mainly relies on external dampers such as vibration dampers and spacers to suppress vibration. These devices need to be installed separately, which increases costs and wind resistance. Moreover, their effectiveness is greatly affected by the installation location. They have limited effect on suppressing low-frequency vibration and cannot meet the needs of normal use.

[0005] Therefore, this invention requires the design of an overhead insulated conductor resistant to wind resistance to solve the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a novel overhead insulated conductor that incorporates a wind-resistant buffering mechanism in its main body structure, particularly its connection and terminal structures, and can effectively suppress wind vibration.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an overhead insulated conductor resistant to wind resistance, comprising a wind-resistant sheath: The first protective jacket has a first insulating disc evenly distributed on the outside of the first protective jacket and a plurality of cables disposed at the end of the first protective jacket away from the wind-resistant sheath. The second protective jacket has a second insulating disc evenly distributed on the outside of the second protective jacket and a terminal block located at the end of the second protective jacket away from the wind resistance sheath. The interior of the second protective jacket also has a conductor core. One end of the conductor core is provided with a connection end, which is detachably electrically connected to the wiring terminal through a clip; The wind-resistant sheath is provided with a limiting sleeve, a hollow sleeve and a spring sleeved on the outside of the hollow sleeve. The hollow sleeve is connected to the connecting structure on the side of the second conductor segment and can slide relative to the limiting sleeve to buffer axial tension.

[0008] In a preferred embodiment of the present invention, the sleeve has a slot inside, and the inner wall of the sleeve is fitted with symmetrically distributed buffer pads. The buffer pads and the slots work together to limit the installation of the wiring terminals and provide protection, thereby extending the service life of the equipment.

[0009] In a preferred embodiment of the present invention, the limiting sleeve has a first sliding groove for mounting the hollow sleeve, and the hollow sleeve has a second sliding groove for mounting the terminal block. The terminal block can pass through normally through the two sliding grooves.

[0010] In a preferred embodiment of the present invention, both the first protective jacket and the second protective jacket are made of weather-resistant polyvinyl chloride. The first protective jacket and the second protective jacket are symmetrically distributed on both sides of the wind-resistant sheath, and as they extend towards both ends, their inner diameter increases to form a frustum structure.

[0011] In a preferred embodiment of the present invention, each cable is provided with an inner layer extending into the first protective jacket. The multiple inner layers are used to bundle the corresponding cables for easy connection.

[0012] In a preferred embodiment of the present invention, an electrical insulation intermediate layer is installed inside the second sealing sleeve, a reinforcing layer is installed inside the first sealing sleeve, a first sealing ring is installed inside the second sealing sleeve and outside the electrical insulation intermediate layer, and a first sealing ring with the same structure as the inside of the second sealing sleeve is installed inside the first sealing sleeve and outside the reinforcing layer. The first sealing ring, the electrical insulation intermediate layer, and the reinforcing layer provide multiple protective effects at the connection point when the wind resistance sleeve and the first protective outer sleeve, the wind resistance sleeve and the second protective outer sleeve are connected, thereby extending the service life of the equipment.

[0013] In a preferred embodiment of the present invention, a third sealing sleeve is installed at one end of the second protective sleeve and outside the terminal. The third sealing sleeve has a second inner cavity that matches the terminal for positioning. The second inner cavity is made of silicone rubber. The first and second sealing sleeves are both made of EPDM rubber. The electrical insulation intermediate layer is made of cross-linked polyethylene. The reinforcing layer is made of aramid fiber reinforced composite material.

[0014] In a preferred embodiment of the present invention, the second protective jacket has a second inner cavity extending into the third sealing ring, and a second sealing ring for use with the cable is installed on the outer side of one end of the first protective jacket. The first protective jacket has a first inner cavity extending into the second sealing ring, thereby ensuring the normal installation of the conductor core.

[0015] In a preferred embodiment of the present invention, the first sealing ring is threadedly connected to the electrical insulation intermediate layer, the first sealing ring is threadedly connected to the second sealing sleeve, the reinforcing layer is threadedly connected to another first sealing ring, and the other first sealing ring is threadedly connected to the first sealing sleeve.

[0016] In a preferred embodiment of the present invention, the second inner cavity is threadedly connected to the third sealing sleeve, the third sealing sleeve is threadedly connected to the second protective outer sleeve, and the second sealing ring is threadedly connected to the first protective outer sleeve. Through multiple sets of structural threaded connections, the overall equipment can be quickly disassembled and assembled, thereby facilitating subsequent modular maintenance, reducing the labor intensity of manual maintenance, and the overall equipment does not use electrical equipment to assist in operation and installation, saving overall usage and installation costs.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention comprises a wind-resistant sheath, a first protective outer jacket, and a second protective outer jacket. The wind-resistant sheath is the core functional module. When strong winds act on the conductor, generating an axial force that pulls the first and second protective outer jackets apart, this force is transmitted through the first and second sealing sleeves to the internal limiting sleeve and hollow sleeve. The hollow sleeve can slide along the first groove inside the limiting sleeve, simultaneously compressing the spring on its outer side. The spring absorbs wind energy through elastic deformation, converting the instantaneous impact force into a gentle restoring force, preventing the pulling force from acting directly and completely on the connection end and the wiring end. This significantly reduces the amplitude of micro-wind vibration and secondary span oscillation, reducing fatigue sources at the source. The conductor core achieves a detachable mechanical and electrical connection with the jacket and wiring end through the connection end. The buffer pad provides contact pressure and buffers fretting friction. The multi-layer sealing structure, such as the first, second, and third sealing... The sheath and sealing ring are made of weather-resistant materials such as EPDM rubber, and are connected to the weather-resistant PVC protective jacket via threads. This ensures the long-term sealing of the connection between the flexible connection section and the conductor sections on both sides, as well as the cable outlet, preventing moisture intrusion and corrosion of the conductor and connection points. The internal reinforcement layer is made of aramid fiber reinforced composite material, providing extremely high tensile strength and creep resistance. It works in conjunction with the spring buffer mechanism to share the mechanical load. All critical connections are threaded, eliminating the need for special crimping or welding tools, and supporting rapid on-site disassembly and modular replacement, greatly reducing the difficulty and cost of operation and maintenance. Multiple sets of threaded connections facilitate rapid disassembly and assembly of the entire equipment, thereby facilitating subsequent modular maintenance and reducing the labor intensity of manual maintenance. The entire equipment does not use electrical equipment to assist in operation and installation, saving overall operating and installation costs. Attached Figure Description

[0027] In this design, a third sealing sleeve 32 is installed at one end of the second protective jacket 3 and outside the terminal 33.

[0030] In this design, the second inner cavity 34 is threaded to the third sealing sleeve 32, the third sealing sleeve 32 is threaded to the second protective outer sleeve 3, and the second sealing ring 24 is threaded to the first protective outer sleeve 2. Through multiple sets of threaded connections, the overall equipment can be quickly disassembled and assembled, which facilitates subsequent modular maintenance, reduces the labor intensity of manual maintenance, and the overall equipment does not use electrical equipment to assist in operation and installation, thus saving overall usage and installation costs.

[0031] Please see Figures 1-6 The working principle of this invention is as follows: It is equipped with a wind-resistant protective sleeve 1, a first protective outer jacket 2, and a second protective outer jacket 3. When in use: Core buffering and force transmission mechanisms: Both sides of the conductor segment: first protective jacket 2 and second protective jacket 3; Flexible connecting section: wind-resistant sheath 1; The wind-resistant protective sleeve 1 is the core functional module. When strong winds act on the conductor and generate an axial force that pulls the first protective sleeve 2 and the second protective sleeve 3 apart, the force is transmitted to the internal limiting sleeve 17 and hollow sleeve 15 through the first sealing sleeve 11 and the second sealing sleeve 12. The hollow sleeve 15 can slide along the first groove inside the limiting sleeve 17, while compressing the spring 16 on its outer side. The spring 16 absorbs wind energy through elastic deformation, converting the instantaneous impact force into a gentle restoring force, thus avoiding the tension from acting directly and completely on the connection end 41 and the wiring end 33. When the wind load decreases or disappears, the spring 16 releases energy, pushing the hollow sleeve 15 to reset, and the conductor returns to its initial length; Wind-induced vibration suppression and aerodynamic design: The first and second insulating discs 31, located on the outside of the first and second protective jackets 3, are equidistantly distributed. These disc-shaped structures can effectively disrupt the laminar flow state of the airflow around the conductor and disrupt the generation of periodic vortex streets, thereby significantly reducing the amplitude of wind vibration and sub-span oscillation, and reducing fatigue sources from the source. Modular sealing and electrical connections: The conductor core 4 is detachably mechanically and electrically connected to the jacket 42 and the terminal 33 through the connection end 41. The buffer pad 43 provides contact pressure and buffers fretting friction. The multi-layer sealing structure, such as the first, second, and third sealing sleeves and sealing rings, is made of weather-resistant materials such as EPDM rubber. It is connected to the weather-resistant PVC protective jacket through threads, ensuring the long-term sealing of the connection between the flexible connection section and the conductor sections on both sides, as well as the cable outlet, and preventing moisture from entering and corroding the conductor and connection point. The internal reinforcing layer 18 is made of aramid fiber reinforced composite material, which provides extremely high tensile strength and creep resistance, and works in conjunction with the spring buffer mechanism to jointly bear the mechanical load; Maintainability design: All critical connections use threaded connections, eliminating the need for special crimping or welding tools, and supporting quick on-site disassembly and modular replacement, which greatly reduces the difficulty and cost of operation and maintenance. The stiffness coefficient k of spring 16 is designed based on the rated breaking force RTS of the conductor and the expected buffer stroke ΔL, satisfying k<0.1*RTS / ΔL, to ensure that energy is mainly absorbed by spring deformation under normal wind vibration. The diameter D of the first insulating disk 21 and the second insulating disk 31 is 1.2-1.5 times the outer diameter of the conductor, and the disk spacing S is 8-12D. This ratio has been verified by wind tunnel test and can generate optimal destructive vortex street in the common wind speed range of 5-25m / s. The use of multiple sets of threaded connections facilitates quick assembly and disassembly of the entire equipment, thereby facilitating subsequent modular maintenance, reducing the labor intensity of manual maintenance, and saving overall usage and installation costs by eliminating the need for electrical equipment to assist in operation and installation. Example: A 10kV wind-resistant tensile strength overhead insulated conductor suitable for coastal typhoon areas Structural parameters: Conductor core 4: High-strength aluminum alloy stranded wire with a cross-section of 120mm²; Flexible connection section length: 800mm; Spring 16: Material 60Si2MnA, stiffness coefficient k=500N / mm, pre-compression 20mm, design maximum buffer stroke ΔL=50mm; First and second insulating discs 31: made of polycarbonate with added UV inhibitor, diameter D=45mm, 1.5 times the outer diameter of the conductor φ30mm, disc spacing S=300mm (10D). Sealing materials: The first and second sealing sleeves 12 are made of EPDM rubber; each sealing ring is made of silicone rubber; Performance test data (compared to traditional JKLYJ wires of the same specification): Dynamic wind load test (simulated on a multi-functional line mechanical testing machine): Conditions: Apply an axial alternating tensile force with an amplitude of ±10kN and a frequency of 0.5Hz (simulating strong wind pulsation) for 50,000 cycles; result: The conductor of this invention: no looseness was found at the conductor core connection point terminal 33, the contact resistance change was <2%, the spring 16 worked normally, and there was no obvious plastic deformation; Existing conductor: Tension clamp connection, obvious fatigue bending marks are visible on the conductor at the clamp exit, some aluminum strands have micro-cracks, and the contact resistance has increased by about 15%; Wind tunnel vibration test: Conditions: Measure the vertical amplitude at the center of the conductor span within a wind speed range of 6-18 m / s; Results: At a wind speed of 12 m / s, which easily induces resonance, the amplitude of the conductor of the present invention is reduced by about 60% compared with that of the traditional smooth-sheathed conductor; Sealing and electrical performance: Conditions: Immerse the connection point in water to a depth of 1 meter and apply a 50kV power frequency voltage; Results: The conductor of this invention showed no leakage at the sealing point, and no breakdown or flashover was observed during long-term withstand voltage tests such as 1000 hours; the insulation resistance remained >5000MΩ. Installation and maintenance: In the simulated field, replacing the end connector of a wire using a regular wrench took about 25 minutes, which is only 1 / 3 of the time required for traditional crimping and potting processes. Conclusion: The data in this embodiment show that the present invention, through the embedded buffer mechanism and aerodynamic insulation disk design, improves the fatigue resistance of overhead insulated conductors in strong wind environments, suppresses wind vibration, and takes into account excellent sealing insulation and modular maintenance convenience. The technical effect is outstanding and verifiable.
