Description

Technical Field

[0001] This invention relates to the field of overhead conductor technology, specifically to a high-strength carbon fiber composite core soft aluminum profile overhead conductor. Background Technology

[0002] Soft aluminum profile overhead conductors are a new type of energy-saving conductor made of annealed soft aluminum stranded together with irregular cross-sections such as trapezoids or Z-shapes. Its core advantage lies in achieving high conductivity, large current carrying capacity, low sag, and high temperature resistance through dual innovation in materials and structure. Carbon fiber composite core soft aluminum profile overhead conductors refer to conductors that use carbon fiber composite cores to replace traditional steel cores to bear mechanical loads, while annealed soft aluminum profiles are used for conductivity, thereby improving the current carrying capacity and corrosion resistance of overhead conductors, reducing the weight of conductors, and minimizing conductor sag.

[0003] However, when existing overhead conductors are used in areas with strong winds, the weight and span of the conductors themselves cause them to sway significantly. Furthermore, most overhead conductors rely on external damping components, but these components affect the conductors' weight, leading to increased sag. This increases the probability that adjacent conductors are prone to colliding and entanglement. Additionally, the conductors' swaying causes friction between the external insulation layer and the overhead support components, resulting in insulation damage and shortening the conductors' lifespan. Summary of the Invention

[0004] This invention provides a high-strength carbon fiber composite core soft aluminum profile overhead conductor, which can effectively solve the problems mentioned in the background art. When existing overhead conductors are used in strong wind areas, the overhead conductors will sway significantly due to their own weight and span.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention features a multi-component buffer internal pressure-relieving mechanism. A fixed-weight spring restricts the dual-cavity combined box and the multi-groove swing block. The force-driven swing of the multi-groove swing block, combined with the internal filling oil, generates compression damping, adjusting the overall oscillation speed and amplitude. Further, the outer buffer frame, external heat dissipation strip, multi-groove pressure-relieving frame, pressure-relieving flame-retardant sponge, and spiral multi-groove frame provide oscillation impact and compression energy absorption, achieving both central swing damping energy absorption and external impact energy absorption. A fully circular flexible sleeve and a low-friction flexible sheet isolate the central stranded load-bearing rope from the composite core, achieving... To reduce friction and electrochemical losses in the battery cells and support ropes, and slow down the wear rate of the overall components, vibration counteraction is achieved at multiple locations. This avoids accelerated aging of materials due to resonance caused by a fixed oscillation frequency inside the overhead conductor, while also achieving overall oscillation energy absorption and buffering, reducing the impact of wind on the overhead conductor. At the same time, it reduces the number of external damping components, improves the internal support strength and service life, reduces the probability of increased sag and mutual collision and entanglement of the overhead conductors, and simultaneously reduces the intensity of external friction of the overhead conductor, slowing down the rate of insulation damage and extending the service life of the overhead conductor.

[0016] 2. This invention is equipped with an external pull-out adjustment mechanism, which strengthens the conductor core and wraps the outer edge through a central multi-position support component. Combined with an external buffer bending component and an external active spacing adjustment component, and through internal layer-by-layer wrapping and limiting, internal elastic expansion and contraction and external manual expansion and contraction components, it ensures the bending range of the overhead conductor during transportation. It also adjusts the tensile strength and bending range of the overhead conductor itself according to the actual environment, which avoids the problem of excessive sag of the overhead conductor affecting the environment and its own safety, and avoids the situation of excessive straightening of the overhead conductor damaging the conductor core due to pressure. This improves the stability of the overhead conductor itself and its applicability to the environment.

[0017] 3. This invention is equipped with a multi-clamping and buffering mechanism. Through multiple clamping components, the overhead conductor and the overhead components are combined. In conjunction with the swing block, hydraulic damper and double-clamp high-friction ring, multi-position damping and energy absorption treatment is carried out to achieve active energy absorption and buffering for small-amplitude swings. The buffering and energy absorption components are transferred to the overhead support position. Without increasing the overall weight of the overhead conductor, the wind and vibration resistance of the overhead conductor is improved. At the same time, direct friction between the support structure and the insulation layer of the overhead conductor is avoided, reducing the probability of insulation damage and extending the service life of the overhead conductor insulation layer.

[0018] In summary, this invention integrates passive damping components and multi-segment combined energy absorption treatment internally, along with external active curvature adjustment and support point damping treatment. This enables control and adjustment of sag during long-span overhead conductor laying. Furthermore, the multi-segment buffering controls the actual sway amplitude of the overhead conductor caused by its own weight and the external environment, reducing the probability of collisions and entanglement between the overhead conductors. Simultaneously, it provides protection for the external insulation layer. Without requiring numerous external components, this invention stabilizes the overall operating posture of the overhead conductor, extends its overall service life, and allows the overhead conductor to operate steadily and efficiently in intelligent power distribution systems.

An inner insulating tube 205 is sleeved on the outer end of the composite wire core 204. An inner semiconducting sheet 206 is wound at equal intervals around the outer end of the inner insulating tube 205. The inner semiconducting sheet 206 has two layers to stabilize the internal protection. A metal shielding strip 207 is wound around the outer end of the inner semiconducting sheet 206.

Several spiral multi-groove frames 217 are equidistantly embedded at the outer end of the pressure-reducing flame-retardant sponge 216. Several spiral multi-groove frames 217 have diameter control and anti-tension strips 218 wound around their outer ends. The outer ends of the diameter control and anti-tension strips 218 are attached to the inner ends of the intermediate flexible insulating tube 1 to ensure multi-position compaction and internal clamping restriction, avoid loosening of the internal wire core due to bending and transportation, and improve the tightness of the overhead conductor. The outer ends of the intermediate flexible insulating tube 1 are bonded with heat insulation sheets 219.

[0023] The external extraction and adjustment mechanism 3 includes a split twisted rope 301 set inside the double-splitting UV-resistant insulating tube 5. The outer end of the split twisted rope 301 is sleeved with a triple multi-control support frame 302. The outer end of the heat insulation sheet 219 is attached to the inner end of the triple multi-control support frame 302 and the support limiting block 303 to achieve bidirectional heat insulation and temperature control treatment, avoiding the impact of the external low temperature environment on the internal battery cell operating environment. The longitudinal section of the triple multi-control support frame 302 is Y-shaped to achieve multi-directional synchronous linkage support treatment. Several load-bearing limiting blocks 303 are equidistantly bonded to the outer end of the three-link multi-control load-bearing frame 302, and several pressure-reducing air bags 304 are equidistantly bonded to the outer end of the three-link multi-control load-bearing frame 302 at the positions corresponding to the load-bearing limiting blocks 303. Several pressure-reducing air bags 304 are bonded to the outer ends of multi-groove limiting plates 316. One end of the multi-groove limiting plate 316 is bonded to one end of the bearing limiting block 303. The inner end of the pressure-reducing linkage plate 305 is attached to the outer end of the bearing limiting block 303, so as to realize multi-position segmented combination and positioning limiting treatment. The pressure-reducing linkage plates 305 are bonded to the outer ends of the multi-groove limiting plates 316 at equal intervals.

The outer end of the protruding pull rope 310 is fitted with a clamping clamp 312. The outer end of the clamping clamp 312 is fitted with a side-pressing operation frame 314 by a fixing bolt 313. The inner end of the side-pressing operation frame 314 is bonded with a compaction anti-slip plate 315.

The inner end of the compaction anti-slip plate 315 is attached to the outer end of the double-section UV-resistant insulation tube 5 to achieve multi-segment pulling and tightness adjustment.

[0024] The split clamping multi-slow mechanism 4 includes a double-clamping high-friction ring 401 set on the outer end of the double-splitting UV-resistant insulating tube 5. The outer end of the double-clamping high-friction ring 401 is sleeved with a clamping combination frame 402. The two clamping combination frames 402 are connected by fixing bolts 313 and pressing nuts 405 to realize clamping combination processing and ensure the stability of fixed clamping. The outer end of the clamping assembly 402 is rotatably connected to the sliding limit frame 403. The cross-section of the sliding limit frame 403 is T-shaped, which allows the sliding limit frame 403 to be steadily pressed and aligned when connected to the clamping assembly 402. One end of the sliding limit frame 403 is connected to the clamping screw 404. One end of the clamping screw 404 is connected to a compressing nut 405 via a thread, and a pressure-dividing fixing block 406 is sleeved on the outer end of the clamping screw 404. The pressure-dividing fixing block 406 is installed between two sliding limit frames 403 to achieve steady pressure distribution and buffering. Both the clamping assembly frame 402 and the sliding limit frame 403 have a swing block 408 installed at one end by a fixing pin 407. The swing block 408 is inserted into one end of the clamping assembly frame 402 and the sliding limit frame 403 to improve the stability of swing alignment and large swing control. A hydraulic damper 409 is installed between the two swing blocks 408. A double-hole pressure-relieving block 410 is glued to one end of the clamping assembly frame 402.

[0025] The working principle and usage process of this invention are as follows: The multi-groove compression frame 215 and the compression-relieving flame-retardant sponge 216 are bent and compressed to one side, simultaneously compressed and bent in conjunction with the spiral multi-groove frame 217. During compression and bending, the grooves at various positions of the multi-groove compression frame 215 overlap each other, and the grooves of the spiral multi-groove frame 217 overlap synchronously. Compression is achieved in conjunction with the compression-relieving flame-retardant sponge 216, and diameter and overall shape control are achieved with the diameter-controlling anti-tension belt 218. This allows for significant internal folding and compression when the overhead conductor is bent, thereby reducing... The bending amplitude of the internal center stranded load-bearing rope 201 and composite core 204 is buffered by the pressure relief air bag 304 and the two sets of load-bearing limiting blocks 303. It is also pulled and limited by the multi-groove limiting plate 316 and the pressure relief linkage plate 305. It is also softly folded and linked with the guide operation frame 308 and the isolation soft pressure sleeve 309 to realize multi-segment synchronous bending linkage processing, expand the buffer control of the overhead conductor filling position, and thus reduce the damage to the internal power supply components of the overhead conductor caused by bending during transportation and production winding by using a two-segment buffer connection. During the overhead conductor laying, workers use traction equipment to move the overhead conductor along a pre-set route. A set of double-clamp high-friction rings 401 are attached to the outer end of the double-section UV-resistant insulating tube 5 on the outside of the overhead line. Then, the clamp assembly frame 402 is fitted and connected to the double-hole pressure relief block 410, ensuring that the double-clamp high-friction rings 401 on the inner side of the clamp assembly frame 402 are fitted and connected to the double-clamp high-friction rings 401 on the outer end of the double-section UV-resistant insulating tube 5. After fitting, the clamp assembly frame 402 is pressed and fixed using fixing bolts 313 and compacting nuts 405. After fixing, two sets of sliding restraint frames 403 are fitted onto the outer end of the clamp assembly frame 402. The pressure-reducing fixing block 406 is placed between the two sliding limit frames 403, and the clamping screw 404 is passed through the sliding limit frame 403, the pressure-reducing fixing block 406 and the overhead line platform. The clamping nut 405 is used to press and fix the sliding limit frame 403, the pressure-reducing fixing block 406 and the overhead line platform, thereby providing overhead support for the overhead conductor. Then, the processing swing blocks 408 at both ends of the hydraulic damper 409 are inserted between the sliding limit frame 403 and the pressure-reducing fixing block 406, and the fixing pin 407 is used to press and fix the processing swing blocks 408, the sliding limit frame 403 and the pressure-reducing fixing block 406, thereby fixing the overhead support part of the overhead conductor. After the overhead conductor is fixed, the staff pulls the outward-protruding pull rope 310 on the outside of the double-ended UV-resistant insulation tube 5. The outward-protruding pull rope 310 pulls the pull blocking block 311 along the guide operating frame 308 and the isolation soft pressure sleeve 309 to achieve the engagement of the pull blocking block 311 and the guide operating frame 308. Then, the clamping clamp 312 is pressed onto the outer end of the outward-protruding pull rope 310, and the compacted anti-slip plate 315 is attached to the outer end of the double-ended UV-resistant insulation tube 5. The side-pressing operating frame 314 is pressed onto one end of the clamping clamp 312. The clamping clamp 312 and the side-pressing operating frame 314 are pressed and fixed by the fixing bolt 313 and the compacting nut 405, thereby clamping and restricting the outward-protruding pull rope 310, providing lateral support to the outside of the overhead conductor, and strengthening it through internal fixed support to control the flexibility of the overhead conductor and ensure that the sag of the conductor can be reduced when it is suspended in a large span. During overhead support and operation, power is supplied through the composite core 204 inside the overhead conductor. During operation, the central stranded load-bearing rope 201 is isolated from the composite core 204 by the round flexible sleeve 202 and the low-friction flexible sheet 203. This prevents the aluminum in the composite core 204 from forming a potential difference with the carbon in the central stranded load-bearing rope 201, avoiding strong corrosion driving forces caused by potential differences, which could lead to electrochemical corrosion between the internal conductive core and the carbon fiber rope of the central support. Simultaneously, it reduces frictional losses from direct contact and minimizes the impact on the central stranded load-bearing rope of the support. In the event of rapid wear and tear of the load-bearing rope 201, the composite core 204 inside is supported by the center stranded load-bearing rope 201, the round flexible sleeve 202, and the low-friction flexible sheet 203. This ensures the flexibility of the overhead conductor itself and improves the overall support capacity of the conductor. In conjunction with the inner insulating tube 205, the double-layer inner semi-conductive sheet 206, the metal shielding strip 207, and the anti-tension compaction filling tape 208, the core is subjected to electromagnetic shielding, internal and external isolation, and edge compaction filling treatment, which reduces internal and external electromagnetic interference and ionization caused by gaps, and stabilizes the operation of the power supply inside the overhead conductor. The center and edges of the triple-linked multi-control bearing frame 302 are pulled and supported by the multi-group twisted rope 301, and the flexible insulating tube 1 of the middle partition is wrapped and supported by the bearing limiting block 303 and the pressure relief air bag 304. The carbon fiber rope support at the cable core position and the carbon fiber rope support of the entire filling layer inside the overhead conductor are reinforced to achieve multi-position force distribution and load-bearing pull, thereby improving the overall load-bearing capacity and support strength of the overhead conductor. The position between the pull blocking block 311 and the guide operation frame 308 is adjusted by the outward pull rope 310. The pull blocking block 311 and the guide operation frame 308 are combined to compact and adjust the outer end of the overhead conductor. The external flexibility is adjusted by the multi-section locking block and cable, and the internal force distribution is combined to reduce the overall sag of the conductor when it is laid in a large span. When an overhead conductor is continuously supplying power, it will sway to different amplitudes due to its own weight and the influence of the external environment. When the overall sway amplitude is small, the overhead conductor drives the double-clamp high-friction ring 401 and the clamp combination frame 402 to sway along the sliding limit frame 403. The clamp combination frame 402 pulls the swing block 408 and the hydraulic damper 409 to rotate and pull at the same time. The hydraulic damper 409 absorbs energy and buffers it. In conjunction with the double-clamp high-friction ring 401, they rub against each other to generate damping, realizing external energy absorption and buffering when the sway amplitude is small. It also avoids direct friction between the support structure and the insulation layer of the overhead conductor, reduces the probability of insulation damage, and extends the service life of the outer insulation layer of the overhead conductor. When the overhead conductor swings significantly, and the overall swing of the overhead conductor exceeds the limiting force of the fixed weight spring 212 on the multi-slot swing block 213, the multi-slot swing block 213 inside the overhead conductor swings along the double-cavity joint box 211. At this time, the multi-slot swing block 213 pushes the hydraulic oil in the double-cavity joint box 211 and squeezes the hydraulic oil. Through the squeezing damping, energy is absorbed. With the help of some hydraulic oil entering the double-cavity joint box 211 along the multi-slot swing block 213, the kinetic energy and inertia can be converted into heat energy. With the help of the external elastic expansion component, swings at different speeds are formed. Through the swings at different speeds, small-amplitude oscillations are formed inside the overhead conductor. Through the collision and small-amplitude torsion between the internal oscillation and the external swing, the kinetic energy of the swing is converted into heat energy, thereby realizing secondary energy consumption. By using the internal vibration damping and energy absorption buffer in different directions and irregularities, when the overhead conductor swings significantly, it can be combined with the external damping buffer component to slow down its swing speed and reduce its swing amplitude, so as to avoid the collision and entanglement of adjacent overhead conductors due to excessive swing. Meanwhile, during the buffering process, the heat insulation limiting sleeve 210 and the external heat dissipation strip 214 are used to perform directional heat conduction treatment on the positions of the buffer assembly frame 209 and the double cavity combined box 211 to avoid the heat generated by the damping from affecting the stable operation of the internal conductive components and support components. The external heat insulation sheet 219 is used for temperature control, and the heat dissipation area is expanded in the middle to stabilize the internal temperature and avoid the impact of external high temperature or low temperature on the operation of internal components.
