Description

Technical Field

[0001] This application relates to the field of cable technology, and in particular to a high-temperature resistant aluminum-clad steel core heat-resistant aluminum alloy stranded wire. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of conductors. Among them, aluminum-clad steel core aluminum stranded wire is a type of conductor used in cables, which has advantages such as good corrosion resistance and long service life.

[0003] Chinese Patent No. CN222749241U discloses a steel-cored heat-resistant aluminum alloy stranded wire, comprising an ultra-high strength galvanized steel wire, wherein the ultra-high strength galvanized steel wire is composed of multiple ultra-high strength galvanized steel monofilaments wound together; an ultra-high strength steel core inner layer is spirally wound on the outer surface of the ultra-high strength galvanized steel wire, and an ultra-high strength steel core outer layer is spirally wound on the outer surface of the ultra-high strength steel core outer layer; and a heat-resistant aluminum alloy conductor inner layer is spirally wound on the outer surface of the ultra-high strength steel core outer layer.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: In actual operation, the steel-clad steel-core heat-resistant aluminum alloy stranded wire exhibits a significant difference in the coefficients of linear expansion between steel and aluminum. Under high-temperature operating conditions, this difference leads to uneven thermal expansion of the conductor. Aluminum has a relatively large coefficient of linear expansion, causing the aluminum portion to elongate considerably at high temperatures, while the steel core elongates relatively less. This results in a significant increase in the sag of the entire conductor. This significant increase in sag may lead to insufficient distance between the conductor and the ground, violating electrical safety regulations and exposing the conductor to risks such as contact with ground objects or lightning strikes, seriously affecting the safe operation of the line. Therefore, a high-temperature resistant aluminum-clad steel-core heat-resistant aluminum alloy stranded wire is proposed to solve the aforementioned problems. Summary of the Invention

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, the mercury inside the installation cylinder expands or contracts with temperature changes, pushing the moving plate and the transmission shaft. The transmission shaft, through the connecting sleeve, links the fixing block of the synchronous component, causing the V-shaped inclined groove inside the fixing block to drive the roller to roll, thereby pushing the displacement rod to the left and right sides to lift the second half-arc sleeve of the guide component, effectively offsetting the thermal expansion of the aluminum layer and actively suppressing the increase of sag from a mechanical perspective.

[0026] 2. In this invention, the protective sleeve of the conductor body is tightly attached to the first semi-circular jacket by the heat-conducting rubber sheet on the inner wall. This not only enhances the friction between the first semi-circular jacket and the conductor body to prevent slippage, but also quickly conducts the heat generated by the conductor body during operation to the mounting cylinder, providing a precise temperature signal for mercury expansion. At the same time, the cooperation between the first connecting screw and the first connecting block enables detachable installation, which is convenient for later maintenance and replacement, taking into account both functionality and practicality.

[0027] 3. In this invention, two sets of second semi-circular sleeves are symmetrically distributed on both sides of the connecting component to provide symmetrical support points for the displacement rod of the synchronization component; the displacement rod is inclined and its bottom end is hinged to the second semi-circular sleeve. With the sliding fit of the roller and the inclined groove, the displacement rod drives the second semi-circular sleeve to move when it is unfolded, generating a uniform upward lifting force, avoiding deformation caused by uneven local stress on the conductor body, adapting to the arc contour of the conductor body, and improving adjustment stability.

[0028] 4. In this invention, when the conductor body is shaken by wind, the wind vane is driven by the airflow to rotate the disc, and the gravity block expands outward along the annular groove of the limiting seat under the action of centrifugal force. The sliding sleeve is pulled along the transmission shaft by the connecting rod, and with the buffering effect of the elastic telescopic rod, part of the wind load impact force is offset. At the same time, the tension spring can pull the transmission shaft to reset, avoiding the wind force causing the synchronization component to over-adjust, and enhancing the operational stability of the conductor body in complex wind environments.

[0029] 5. In this invention, when the second semi-arc sleeve moves with the displacement rod, it drives the connecting ear of the cooling component to pull the plug rod downward. As the plug rod moves downward, it compresses the return spring, causing the plug plate to move downward and send the coolant through the check valve and the delivery pipe to the spray nozzle to spray and cool the conductor body. When the displacement rod returns to its original position, the piston cylinder draws coolant from the storage tank through the extraction pipe, reducing the thermal expansion of the aluminum layer and helping to suppress the increase of sag, thus achieving a dual arc control effect of mechanical adjustment and physical cooling.

[0032] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0033] This application discloses a high-temperature resistant aluminum-clad steel-core heat-resistant aluminum alloy stranded wire. Please refer to... Figures 1 to 9 A high-temperature resistant aluminum-clad steel core heat-resistant aluminum alloy stranded wire includes a conductor body 1. The conductor body 1 includes an insulation layer 11, a positioning layer 12, an inner sheath layer 13, a transmission conductor 14, an annular heat dissipation fins 15, and a protective sleeve 16. A connecting component 2 and a guiding component 3 are detachably connected to the outside of the conductor body 1. A synchronization component 5 is provided on the outside of the guiding component 3 to lift the conductor body 1 upward. A transmission structure 4 and a cooling component 6 are provided on the top of the connecting component 2, which are respectively linked with the synchronization component 5 and the guiding component 3.

[0034] Specifically, the positioning layer 12 is disposed inside the insulation layer 11, the inner sleeve layer 13 is fixedly connected between the insulation layer 11 and the positioning layer 12, the power transmission conductor 14 is fixedly connected inside the inner sleeve layer 13, the annular heat dissipation fins 15 are fixedly connected inside the positioning layer 12, and the protective sleeve 16 is fitted over the outside of the insulation layer 11. By setting the insulation layer 11 to ensure electrical safety, the positioning layer 12 and the inner sleeve layer 13 to improve structural stability, the annular heat dissipation fins 15 to expand the heat dissipation area to accelerate heat dissipation, and the protective sleeve 16 to enhance external protection, the whole system achieves dual protection of high temperature resistance and safe power transmission.

[0035] To provide a basis for subsequent cooling and sag reduction, the connecting component 2 includes two first semi-circular sleeves 21 that are sleeved on the outside of the protective sleeve 16. One side of the two first semi-circular sleeves 21 is hinged, and the inner wall of each of the two first semi-circular sleeves 21 is fixedly connected to a heat-conducting rubber sheet 22 that abuts against the outer wall of the protective sleeve 16. The other side of each of the two first semi-circular sleeves 21 is fixedly connected to a first connecting block 23, and the internal thread of the first connecting block 23 is connected to a first connecting screw 24.

[0036] In order to achieve symmetrical support and stable lifting effect for the conductor body 1, in this embodiment, the guide component 3 includes two second semi-circular sleeves 31 that are sleeved outside the protective sleeve 16. One side of the two second semi-circular sleeves 31 is hinged, and the other side of the two second semi-circular sleeves 31 is fixedly connected to a second connecting block 32. The second connecting block 32 is threadedly connected to a second connecting screw 33.

[0037] The guide components 3 consist of two sets, symmetrically distributed on the outside of the connecting component 2. Two sets of second semi-circular sleeves 31, symmetrically distributed on both sides of the connecting component 2, provide symmetrical support points for the displacement rod 52 of the synchronization component 5. The displacement rod 52 is inclined and its bottom end is hinged to the second semi-circular sleeve 31. With the sliding fit of the roller 54 and the inclined groove 55, the displacement rod 52, when unfolded, drives the second semi-circular sleeve 31 to displace, generating a uniform upward lifting force. This avoids deformation caused by uneven local force on the conductor body 1, adapts to the arc-shaped contour of the conductor body 1, and improves adjustment stability. The symmetrically distributed guide components 3 balance the lateral force on the conductor body 1, preventing displacement of the conductor body 1 caused by unilateral force. During the lifting process, they always conform to the arc-shaped contour of the conductor body 1, further improving the overall structural stability.

[0038] To convert the temperature change of the conductor body 1 into mechanical power and actively suppress the increase of sag, in this embodiment, the transmission structure 4 includes a mounting cylinder 41 disposed on the top of the connecting assembly 2 and mercury 42 disposed inside the mounting cylinder 41. A movable plate 43 is disposed on the top of the mercury 42, and a transmission shaft 44 is rotatably connected to the top of the movable plate 43. As the mercury 42 inside the mounting cylinder 41 expands or contracts with temperature changes, it pushes the movable plate 43 and the transmission shaft 44. The transmission shaft 44, through the connecting sleeve 413, links the fixing block 51 of the synchronization assembly 5, causing the V-shaped inclined groove 55 inside the fixing block 51 to drive the roller 54 to roll, thereby pushing the displacement rod 52 to the left and right to lift the second half-arc sleeve 31 of the guide assembly 3, effectively offsetting the thermal expansion of the aluminum layer and actively suppressing the increase of sag from a mechanical perspective.

[0039] The mounting cylinder 41 is fixedly connected to the top of the first semi-circular sleeve 21, the drive shaft 44 is disposed through the upper surface of the mounting cylinder 41, the outer surface of the top end of the drive shaft 44 is fitted with a connecting sleeve 413, and the fixing block 51 is fixedly connected to the outside of the connecting sleeve 413.

[0040] Specifically, a bearing sleeve 45 is fixedly connected to the outside of the drive shaft 44, a disc 46 is rotatably connected to the top of the bearing sleeve 45, a limiting seat 47 is fixedly connected to the bottom of the disc 46, and multiple sets of wind vanes 48 are fixedly connected to the outside of the limiting seat 47. The multiple sets of wind vanes 48 are arranged in a ring shape outside the limiting seat 47. A tension spring 414 is fixedly connected between the bearing sleeve 45 and the mounting sleeve 41, and the tension spring 414 is connected to the outside of the drive shaft 44.

[0041] To ensure stable operation of the transmission structure 4 in complex wind environments, it should be noted that the transmission shaft 44 is externally slidably connected to a sliding sleeve 49, and a connecting sleeve 413 is rotatably connected to the top of the sliding sleeve 49. A connecting rod 410 is hinged to the outside of the sliding sleeve 49, and a gravity block 411 is hinged to the bottom end of the connecting rod 410. An annular groove adapted to the gravity block 411 is opened inside the limiting seat 47. An anti-slip rubber pad is fixedly connected to the side of the gravity block 411 near the limiting seat 47. The gravity block 411 abuts against the inner wall of the annular groove. An elastic telescopic rod 412 is fixedly installed between the gravity block 411 and the disc 46. There are two sets of connecting rod 410, gravity block 411 and elastic telescopic rod 412. When the conductor body 1 is shaken by the wind, the wind vane 48 is driven by the airflow to rotate the disc 46. The gravity block 411 expands outward along the annular groove of the limiting seat 47 under the action of centrifugal force. The connecting rod 410 pulls the sliding sleeve 49 to slide along the transmission shaft 44. With the buffering effect of the elastic telescopic rod 412, part of the wind load impact force is offset. At the same time, the tension spring 414 can pull the transmission shaft 44 to reset, avoiding the wind force causing the synchronization component 5 to over-adjust, and enhancing the operational stability of the conductor body 1 in complex wind environments.

[0042] To ensure the stability and adaptability of the lifting adjustment, in this embodiment, the synchronization component 5 includes a fixing block 51 disposed on the top of the connecting component 2 and a displacement rod 52 disposed outside the fixing block 51. A pin 53 is rotatably connected to the outside of the displacement rod 52. A roller 54 is fixedly connected to one end of the pin 53 away from the displacement rod 52. An inclined groove 55 adapted to the roller 54 is opened inside the fixing block 51.

[0043] The outer diameter of the roller 54 matches the inner diameter of the inclined groove 55. The bottom end of the displacement rod 52 is hinged to the top of the second semi-circular sleeve 31. There are two sets of displacement rods 52, rollers 54, and inclined grooves 55. The two sets of inclined grooves 55 are distributed in a V-shape, and the two sets of displacement rods 52 are distributed in an inclined manner on the surface of the conductor body 1. By tilting the displacement rods 52 and hinged their bottom ends to the second semi-circular sleeve 31, and by sliding the rollers 54 with the inclined grooves 55, the displacement rods 52 drive the two second semi-circular sleeves 31 to move to the left and right sides when they are unfolded, generating a uniform upward lifting force. This avoids deformation caused by uneven local stress on the conductor body 1, adapts to the arc-shaped contour of the conductor body 1, and improves the adjustment stability.

[0044] To achieve physical cooling and sag suppression of the conductor body 1, the cooling assembly 6 includes a piston cylinder 61, a liquid storage tank 64, and two sets of nozzles 62 fixedly connected to the outside of the second semi-arc jacket 31. A stopper plate 65 is slidably connected inside the piston cylinder 61. A stopper rod 66 is fixedly connected to the top of the stopper plate 65, penetrating the piston cylinder 61. A connecting lug 67, which is hinged to the bottom of the displacement rod 52, is fixedly connected to the top of the stopper rod 66. A return spring 68 is fixedly connected between the connecting lug 67 and the piston cylinder 61.

[0045] Specifically, an extraction pipe 69 is fixedly connected between one side of the piston cylinder 61 and the liquid storage tank 64, and a check valve 610 is fixedly connected to the other side of the piston cylinder 61. A delivery pipe 611 is fixedly connected between the check valve 610 and the top spray pipe 62, and a hose 63 is fixedly connected between the two sets of spray pipes 62. Spray holes facing the conductor body 1 are opened on opposite sides of the two sets of spray pipes 62. When the second half-arc sleeve 31 moves with the displacement rod 52, it drives the connecting ear 67 of the cooling component 6 to pull the plug rod 66 downward. When the plug rod 66 moves downward, it compresses the return spring 68, causing the plug plate 65 to move downward and send the coolant through the check valve 610 and the delivery pipe 611 to the spray pipe 62 to spray and cool the conductor body 1. When the displacement rod 52 returns to its original position, the piston cylinder 61 extracts coolant from the liquid storage tank 64 through the extraction pipe 69, reducing the thermal expansion of the aluminum layer, helping to suppress the increase of sag, and achieving a dual arc control effect of mechanical adjustment and physical cooling. Combined with appendix Figures 1 to 9 The working principle of the above embodiments is as follows: The conductor body 1 is composed of an insulation layer 11, a positioning layer 12, an inner sleeve layer 13, a power transmission conductor 14, an annular heat dissipation fins 15, and a protective sleeve 16. The insulation layer 11 ensures electrical safety, the annular heat dissipation fins 15 expand the heat dissipation area, and the protective sleeve 16 strengthens external protection. The two first semi-arc sleeves 21 of the connecting component 2 are attached to the protective sleeve 16 through a thermally conductive rubber sheet 22. The second semi-arc sleeves 31 of the two sets of guide components 3 are symmetrically distributed and slide on both sides of the connecting component 2 to provide support for subsequent adjustment. When the temperature of the conductor body 1 rises, the mercury 42 in the top mounting cylinder 41 of the connecting component 2 expands due to heat, pushing the moving plate 43 and the drive shaft 44 to move upward. The drive shaft 44 drives the fixing block 51 of the synchronization component 5 to move upward through the connecting sleeve 413. The V-shaped inclined groove 55 in the fixing block 51 drives the two sets of rollers 54 to roll, thereby pushing the inclined displacement rod 52 to unfold to the left and right. When the displacement rod 52 unfolds, the connecting ear 67 at its bottom hinge pulls the plug rod 66 to move downward, compressing the return spring 68 and driving the plug plate 65 to move downward, sending the coolant in the piston cylinder 61 to the spray pipe 62 through the check valve 610 and the delivery pipe 611, and spraying it onto the conductor body 1 through the spray hole to cool it down. When the temperature drops, the mercury 42 contracts, the drive shaft 44 resets under the action of the tension spring 414, the displacement rod 52 retracts, and the piston cylinder 61 draws coolant from the storage tank 64 through the extraction pipe 69 to prepare for the next cooling. When wind is generated, the airflow drives the annular wind vane 48 outside the limiting seat 47 to rotate, which in turn drives the disc 46 to rotate. Under the action of centrifugal force, the gravity block 411 expands outward along the annular groove, and through the connecting rod 410 pulls the sliding sleeve 49 to slide along the transmission shaft 44. With the buffering of the elastic telescopic rod 412, it indirectly pushes the displacement rod 52 to unfold, and simultaneously triggers the nozzle 62 to spray coolant to cool down. After the wind weakens, the centrifugal force disappears, the elastic telescopic rod 412 pulls the gravity block 411 to reset, the tension spring 414 pulls the transmission shaft 44 back to the initial position, the displacement rod 52 retracts, and the piston cylinder 61 completes the coolant suction, avoiding uneven local force or over-adjustment of the main body 1 due to wind swaying. When the displacement rod 52 is deployed, it will push the second semi-arc sleeves 31 on both sides to move to the left and right, generating a uniform upward lifting force to offset the thermal expansion of the aluminum layer of the transmission conductor 14; at the same time, physical cooling reduces the thermal expansion of the aluminum layer. The two work together to achieve dual arc control through mechanical adjustment and physical cooling. Combined with the passive heat dissipation of the annular heat dissipation fins 15, it ensures that the conductor body 1 operates stably in high temperature and windy environment and avoids the increase of sag.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
