Description

Technical Field

[0001] This invention relates to the field of overhead insulated conductor technology, specifically to a stable overhead insulated conductor with a wind-resistant deflection structure. Background Technology

[0002] Overhead insulated conductors, simply put, are power conductors erected on utility poles and towers, with an insulation layer covering the conductor. Unlike traditional bare steel-core aluminum stranded wires, which rely on air insulation and require a large safety distance between phases and to ground, overhead insulated conductors have an insulating plastic layer extruded over their metal conductive core, providing built-in insulation protection. This reduces the spacing between installations and makes them less prone to phase-to-phase short circuits. They are mainly used in urban and rural 1kV, 10kV, and 35kV distribution networks. For this purpose, a Chinese patent discloses a wind-resistant low-altitude overhead insulated conductor, application number CN202411832620.1. This patent prevents the surface of the conductor from cracking or breaking after prolonged use, and also improves the stability and wind resistance of the conductor when used overhead, preventing damage caused by significant swaying when blown by the wind.

[0003] However, during prolonged vibration, the conductive components inside the overhead line will undergo relative displacement synchronously with the cable's swing. This leads to wear and aging of the components inside the cable during continuous vibration, resulting in a decrease in the overall conductivity of the cable and a reduction in its service life.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. An internal flexible buffer protection mechanism is set up. Through the cooperation between the various components of the internal flexible buffer protection mechanism, the overall protection process of the overhead line is optimized. Through the multi-layer flexible structure inside the overhead line, when the overhead line vibrates in a light wind environment, the kinetic energy of the overhead line is consumed by the expansion and contraction deformation of the elastic buffer bag and the alternating swing of the counterweight swing bar. The reciprocating expansion and contraction deformation of the elastic buffer bag and the alternating swing of the counterweight swing bar form a synergistic energy dissipation effect, continuously dissipating the vibration kinetic energy of the overhead line. At the same time, the fan-shaped flexible sleeve and the sponge filling block provide additional offset buffer and displacement constraint for the internal transmission conductor through their own flexible deformation, effectively avoiding mutual friction and loss of the internal components of the overhead line during vibration, and significantly extending the overall service life of the overhead line. Meanwhile, through the flexible deformation structure outside the arc-shaped connecting bracket, the kinetic energy inside the internal transmission conductor is transferred through relative deflection displacement between the arc-shaped connecting bracket and the flexible silicone sheet during the vibration of the overhead line. The flexible silicone sheet and its outer silicone support wing can sway before the internal structure of the overhead line under the action of airflow. The swaying of the flexible silicone sheet and silicone support wing consumes the kinetic energy of the overhead line, further reducing the relative displacement amplitude of the internal transmission conductor and internal related components, effectively improving the adaptability of the overhead line to complex environments, and thus effectively reducing the relative displacement amplitude of the internal transmission conductor and its connected components, effectively improving the overall environmental adaptability of the overhead line.

[0016] 2. A snap-fit ​​dynamic traction protection mechanism is installed. Through the cooperation between the various components inside the snap-fit ​​dynamic traction protection mechanism, the overall protection performance of the overhead line is optimized. Through the flexible support element inside the protective connection shell, a pre-tight constraint can be applied to the outside of the overhead line. By reciprocating the compression limit spring, when the overhead line swings, the axial vibration kinetic energy of the overhead line is transferred and dissipated. In conjunction with the buffer telescopic soft bladder and the limit flexible rubber block, a flexible limit is formed on the outside of the overhead line, improving the telescopic buffer performance of the overhead line and avoiding the traction force generated by the swing from being concentrated on the connection between the overhead line and the terminal frame, which would cause the joint to loosen. This greatly improves the assembly stability and operational reliability of the overhead line, and further enhances the stability and reliability of the overhead line installation. Meanwhile, through the cooperation between the components inside the axially inserted sleeve, the reciprocating sliding of the sliding buffer block, and the alternating extension and contraction of the buffer extension spring, the axial kinetic energy generated by the swing of the overhead line is further consumed, thereby enhancing the overall stability of the overhead line. At the same time, according to the usage environment of the overhead line, an appropriate number of protective connection shells are selected for installation, thereby improving the environmental adaptability of the overhead line.

[0017] In summary, through the cooperation between the internal flexible buffer protection mechanism and the snap-fit ​​dynamic traction protection mechanism, and by adding additional movable components inside and outside the overhead line, the kinetic energy of the overhead line vibration is transferred and consumed by the deflection and movement of the internal components of the overhead line, thus preventing the internal transmission conductors of the cable from losing power due to self-friction. Furthermore, the kinetic energy during the swinging process of the overhead line is transferred and consumed by the expansion and contraction deformation of the movable components inside the protective connection shell, thus preventing the connection points from loosening during the swaying of the overhead line. This effectively improves the environmental adaptability of the overhead line and extends its service life. Attached Figure Description

A limiting support bar 602 is uniformly sleeved on the outside of the central limiting guide cable 601 along the axial direction. A clamping limiting cable 603 is snapped on the outer side of the flexible bundle layer 5. Three internal power transmission conductors 1 and their external covering components are arranged in a circumferential direction on the outside of the central limiting guide cable 601. The outer arc surface of the limiting support bar 602 is tightly fitted with the outer side of the corresponding external insulating barrier layer 4. The outer side of the clamping limiting cable 603 is tightly fitted with the side of the flexible bundle layer 5. The flexible binding layer 5 is filled with a flexible limiting sector box 604 along the circumferential direction on the outer side. A sector flexible sleeve 605 is fixedly connected to the end of the flexible limiting sector box 604. A sponge filling block 606 is filled inside the sector flexible sleeve 605. The ends of the flexible limiting sector box 604 are connected to each other through the sector flexible sleeve 605. The inner arc surface of the flexible limiting sector box 604 and the sector flexible sleeve 605 is tightly fitted to the outer side of the flexible binding layer 5. The flexible limiting sector box 604 is filled with an elastic buffer 607. A counterweight swing bar 608 is embedded in the middle of the outer side of the elastic buffer 607. The elastic buffer 607 is filled with damping oil. The outer arc surface of the elastic buffer 607 and the edge arc surface of the counterweight swing bar 608 are tightly slidably attached to the inner wall of the flexible limiting sector box 604. An arc-shaped connecting bracket 609 is snapped onto the outer side of the flexible limiting fan-shaped box 604 along the circumferential direction. Both ends of the arc-shaped connecting bracket 609 are embedded with insertable clamping cables 610. A flexible sliding groove cotton sheet 611 is bonded to the outer side of the arc-shaped connecting bracket 609. A flexible silicone sheet 612 is snapped onto the outer side of the flexible sliding groove cotton sheet 611. Silicone support wing pieces 613 are evenly bonded to the inner side of the flexible silicone sheet 612. The end faces of the arc-shaped connecting bracket 609 are tightly fitted together, and the end of the arc-shaped connecting bracket 609 is snapped into the gap on the side of the flexible limiting fan-shaped box 604. The silicone support wing pieces 613 are evenly embedded inside the flexible sliding groove cotton sheet 611. A gap is left between the outer side of the silicone support wing piece 613 and the side of the flexible sliding groove cotton sheet 611. A flexible silicone sheet 612 has a spirally wound braided layer 614 on its outer side. A rubber insulating layer 615 tightly covers the outer side of the braided layer 614. The inner side of the braided layer 614 is tightly fitted to the outer side of the flexible silicone sheet 612. The inner layer of the rubber insulating layer 615 is embedded in the gaps between the outer sides of the braided layer 614. Through the cooperation of the various components within the internal flexible buffer protection mechanism 6, the overall protection process of the overhead line is optimized. Through the multi-layered flexible structure inside the overhead line, when the overhead line vibrates in a light wind environment, it is elastically buffered. The expansion and contraction deformation of the bladder 607 and the alternating swing of the counterweight swing bar 608 consume the kinetic energy of the overhead line. The reciprocating expansion and contraction deformation of the elastic buffer bladder 607 and the alternating swing of the counterweight swing bar 608 form a synergistic energy dissipation effect, continuously dissipating the vibration kinetic energy of the overhead line. At the same time, the fan-shaped flexible sleeve 605 and the sponge filling block 606 provide additional offset buffer and displacement constraint for the internal transmission conductor 1 through their own flexible deformation, effectively avoiding mutual friction and loss of internal components of the overhead line during vibration, and significantly extending the overall service life of the overhead line. Meanwhile, through the flexible deformation structure outside the arc-shaped connecting bracket 609, the kinetic energy inside the internal transmission conductor 1 is transferred through relative deflection displacement between the arc-shaped connecting bracket 609 and the flexible silicone sheet 612 during the vibration of the overhead line. The flexible silicone sheet 612 and its outer silicone support wing 613 can sway before the internal structure of the overhead line under the action of airflow. The swaying of the flexible silicone sheet 612 and the silicone support wing 613 consumes the kinetic energy of the overhead line, further reducing the relative offset amplitude of the internal transmission conductor 1 and its internal related components, effectively improving the adaptability of the overhead line to complex environments, and thus effectively reducing the relative offset amplitude of the internal transmission conductor 1 and its connected components, effectively improving the overall environmental adaptability of the overhead line. The rubber isolation layer 615 is provided with a snap-fit ​​dynamic traction protection mechanism 7. The snap-fit ​​dynamic traction protection mechanism 7 is used to isolate and protect the outside of the cable, so as to transfer and consume the kinetic energy during the swaying process of the overhead line through kinetic energy conversion. The snap-fit ​​dynamic traction protection mechanism 7 includes a protective connecting housing 701, a locking bolt 702, a sealing isolation strip 703, a buffer mounting box 704, a buffer telescopic soft bladder 705, a buffer limiting block 706, a support mounting box 707, a compression limiting spring 708, a support arc-shaped block 709, a limiting flexible rubber block 710, an axial insertion sleeve 711, a circular sliding guide plate 712, a buffer telescopic spring 713, and a sliding buffer round block 714; The rubber isolation layer 615 is symmetrically snapped with protective connecting shells 701. Locking bolts 702 are threaded through and installed at the four corners of the two protective connecting shells 701. Sealing isolation strips 703 are glued to the inner side of both ends of the protective connecting shells 701. The inner side of the sealing isolation strips 703 is tightly fitted with the outer side of the rubber isolation layer 615. A gap is left between the inner wall of the protective connecting shells 701 and the outer side of the rubber isolation layer 615. A buffer mounting box 704 is embedded in the middle of one end of the protective connecting shell 701. A buffer telescopic soft bladder 705 is glued to one end inside the buffer mounting box 704. A buffer limiting block 706 is glued to the bottom of the buffer telescopic soft bladder 705. A support mounting box 707 is embedded in the middle of the other end of the protective connecting shell 701. A compression limiting spring 708 is fixedly connected to one end of the support mounting box 707. A support arc-shaped locking block 709 is fixedly connected to the bottom of the compression limiting spring 708 at the bottom position of the support mounting box 707. The end arc surfaces of the buffer limiting block 706 and the support arc-shaped locking block 709 are tightly fitted with the rubber isolation layer 615, and the buffer limiting block 706 and the support arc-shaped locking block 709 on the outside of the two protective connecting shells 701 are staggered and arranged with each other. Both sides of the protective connecting housing 701 are bonded with limiting flexible rubber blocks 710. Axially inserted sleeves 711 are installed at the corners of the protective connecting shell 701. Circular sliding guide plates 712 are slidably installed at both ends inside the axially inserted sleeves 711. Buffer telescopic springs 713 are fixedly connected to the sides of the circular sliding guide plates 712. A sliding buffer block 714 is slidably engaged with the middle of the inner side of the axially inserted sleeve 711. The side of the limiting flexible rubber block 710 is tightly fitted with the outer side of the rubber isolation layer 615, and the outer side of the sliding buffer block 714 is tightly fitted with the inner wall of the axially inserted sleeve 711. Through the mutual cooperation of the various components inside the snap-fit ​​dynamic traction protection mechanism 7, the overhead [protection mechanism] is optimized. The overall protection performance of the line is improved by the flexible support element inside the protective connection shell 701, which can apply pre-tight constraint to the outside of the overhead line. When the overhead line swings, the compression limit spring 708 reciprocates to transfer and dissipate the axial vibration kinetic energy of the overhead line. In conjunction with the buffer telescopic soft bag 705 and the limit flexible rubber block 710, a flexible limit is formed on the outside of the overhead line, which improves the telescopic buffer performance of the overhead line and avoids the traction force generated by the swing from being concentrated on the connection between the overhead line and the terminal frame, causing the joint to loosen. This greatly improves the assembly stability and operational reliability of the overhead line and further enhances the stability and reliability of the overhead line installation. Meanwhile, through the cooperation between the components inside the axially inserted sleeve 711, the reciprocating sliding of the sliding buffer block 714, and the alternating extension and retraction of the buffer extension spring 713, the axial kinetic energy generated by the swing of the overhead line is further consumed, thereby enhancing the overall stability of the overhead line. At the same time, according to the usage environment of the overhead line, an appropriate number of protective connection shells 701 are selected for installation, thereby improving the environmental adaptability of the overhead line.

[0022] The working principle and usage process of this invention: In practical applications, when it is necessary to produce overhead lines, the inner rubber insulation layer 2 and the middle silicone protective layer 3 are extruded and wrapped around the outside of the inner power transmission conductor 1 by an extrusion device. Then, the outer insulation barrier layer 4 is tightly wrapped around the outside of the middle silicone protective layer 3 by a winding device. Next, multiple inner power transmission conductors 1 and their external components are arranged around the outside of the limiting support bar 602 by a splicing device. Then, the flexible binding layer 5 is wrapped around the outside of the outer insulation barrier layer 4 by a winding device, so as to constrain the internal components of the overhead line through the flexible binding layer 5. When it is necessary to splice the external components of the flexible bundling layer 5, the clamping and limiting cable 603 is snapped onto the outside of the flexible bundling layer 5 by the assembly equipment. Then, the flexible limiting fan-shaped box 604 and the fan-shaped flexible sleeve 605 and their components are assembled onto the outside of the clamping and limiting cable 603 by the splicing equipment. Next, the arc-shaped connecting card seat 609 and the flexible silicone sheet 612 are snapped onto the outside of the flexible limiting fan-shaped box 604 by the splicing equipment. Then, the bundling braided layer 614 is wound onto the outside of the flexible silicone sheet 612 by the bundling equipment. Finally, the rubber isolation layer 615 is wrapped onto the outside of the bundling braided layer 614 by the extrusion equipment to complete the production of the overall structure of the overhead line. During the use of overhead lines, the internal transmission conductor 1 needs to be connected to a suitable location to transmit electrical energy. When the cable is subjected to high-altitude airflow and swaying during use, it will generate high-frequency, small-amplitude vibrations in a light wind environment. Simultaneously, the cable vibrates, causing the elastic buffer 607 and counterweight swing bar 608 inside the flexible limiting sector box 604 to vibrate synchronously. At the same time, the counterweight swing bar 608 and the elastic buffer 607 also compress each other during vibration, utilizing the elastic buffer 607... The viscous resistance of the internal damping oil causes the swaying frequency of the overhead line, the swaying frequency of the counterweight swing bar 608, and the elastic deformation frequency of the elastic buffer bladder 607 to be different during continuous swaying. The inertia of the overhead line is converted into the kinetic energy of the counterweight swing bar 608 and the internal energy of the self-friction of the damping oil inside the elastic buffer bladder 607 through inertial force, thereby consuming the vibration kinetic energy of the overhead line. In turn, the inertia inside the elastic buffer bladder 607 and the counterweight swing bar 608 provides auxiliary shock absorption for the overhead line, thereby reducing the overall swaying amplitude of the overhead line. When the airflow velocity outside the overhead line accelerates, the flexible groove cotton sheet 611 and flexible silicone sheet 612 are snapped onto the outside of the flexible limiting fan-shaped box 604 by the arc-shaped connecting bracket 609. When the cable shakes, the density of the internal transmission conductor 1 is nine times that of the external protective structure of the arc-shaped connecting bracket 609. The internal transmission conductor 1 is made of hard metal material, while the external protective structure of the arc-shaped connecting bracket 609 is made of polymer elastic material. This results in different kinetic energy and deformation of the internal transmission conductor 1 and the arc-shaped connecting bracket 609 during cable vibration. Therefore, when the overhead line shakes, the internal and external structures of the cable will have relative displacement, which will cause relative torsion between the flexible groove cotton sheet 611 and the flexible silicone sheet 612. This will form wrinkles on the outside of the bundled braid layer 614 and the rubber isolation layer 615. The deformation of the external components of the arc-shaped connecting bracket 609 will transfer and consume the kinetic energy inside the cable, preventing frictional loss of the internal transmission conductor 1 inside the cable, thereby effectively improving the service life of the overhead line. When it is necessary to buffer and protect the overall tension of the overhead line, the protective connecting shell 701 is installed on the outside of the rubber isolation layer 615 by locking bolt 702, and the end of the protective connecting shell 701 is sealed by sealing isolation strip 703, and then the internal components of the protective connecting shell 701 are installed on the outside of the rubber isolation layer 615. Next, the compression limiting spring 708 and the supporting arc-shaped clip 709 are installed into the protective connection housing 701 through the support mounting box 707. The compression limiting spring 708 applies additional compression force to both ends of the corresponding rubber isolation layer 615, so that the overhead line is in a bent state inside the protective connection housing 701. When the overhead line swings back and forth under the action of strong wind, the tension on the overhead line will change periodically, and the traction force generated by the overhead line will periodically act on the connection position between the overhead line and the terminal frame, causing the overhead line to easily loosen and detach during continuous swing. When the tension on the overhead line increases, the overhead line inside the protective connection housing 701 will be gradually straightened under the action of tension. During the deformation of the overhead line, it will squeeze the compression limiting spring 708 in the opposite direction. In this way, the kinetic energy of the overhead line is consumed by the alternating compression of the compression limiting spring 708, so as to prevent the connection between the overhead line and the terminal frame from loosening. Meanwhile, the buffer telescopic soft bladder 705 and the buffer limiting block 706 are installed on the side of the support mounting box 707 through the buffer mounting box 704, so that the buffer limiting block 706 fills the gap on the side of the rubber isolation layer 615, providing buffer for the deformation process of the overhead line, and the side of the overhead line is clamped by multiple limiting flexible rubber blocks 710 to prevent the overhead line from deflecting during the expansion and contraction process. During the oscillation of the overhead line, the protective connection housing 701 will tilt and oscillate synchronously. The potential energy change during the tilting process of the protective connection housing 701 will cause the sliding buffer block 714 to slide back and forth along the axial insertion sleeve 711. During the sliding of the sliding buffer block 714 to both ends of the axial insertion sleeve 711, the kinetic energy will be transferred to the buffer telescopic spring 713 through the circular sliding guide plate 712. The extension and contraction of the buffer telescopic spring 713 will alternately store and release the kinetic energy during the sliding process of the sliding buffer block 714. At the same time, since the extension and contraction of the telescopic spring 713 and the sliding of the sliding buffer block 714 are lagging behind the vibration process of the overhead line, when the tilting direction of the protective connection housing 701 is opposite to the sliding direction of the sliding buffer block 714, the potential energy converted from the vibration deflection in two different directions of the overhead line will cancel each other out and consume each other, further realizing the self-consumption of kinetic energy on the overhead line and improving the overall stability of the cable.
