Description

Technical Field

[0001] The present invention relates to the field of high-temperature cables, and more particularly to a high-temperature resistant cable that operates stably in a high-temperature environment. Background Art

[0002] Cables are essential carriers of electrical energy and signal transmission and are widely used in power engineering, industrial control, transportation, and other fields. With the continuous increase in the power of electrical equipment and the rise in complex environments such as high temperatures and enclosed spaces, the thermal load on cables during operation has increased significantly. When transmitting current, cables generate Joule heat due to the conductor's resistance. If heat is not dissipated promptly, the insulation material's performance and mechanical strength will deteriorate, ultimately affecting the cable's safe and stable operation. Existing high-temperature-resistant cables mostly rely on the heat resistance of the outer sheath material and natural heat dissipation to reduce temperature rise, but this heat dissipation efficiency is limited under complex operating conditions.

[0003] In actual applications, cables often contain multiple conductors or multiple cables. These conductors may be in close contact during laying and operation, resulting in difficulty in heat dissipation on the contact surface. When operating at high temperatures or under high loads, hot spots are easily formed in local contact areas. Due to the low thermal conductivity of the insulation layer inside the cable, heat is difficult to transfer to the outside in time, resulting in heat accumulation and causing the hot spot temperature to continue to rise. In addition, existing technologies generally lack active adjustment structures for overheating of the contact surface inside the cable, and lack emergency mechanisms that can quickly cool down when the temperature is abnormal and intuitive visual alarm methods. It is difficult to meet the long-term stable operation requirements of cables in high temperatures or harsh environments.

The heat conduction ring and thermal expansion block arranged on the outer periphery of the inner cable can automatically expand the distance between the inner and outer cables through the thermal expansion effect when the temperature rises, reduce the direct contact heat transfer path and form an air channel.

[0037] The outer periphery of the heat-conducting ring 13 is fixedly connected with a plurality of evenly distributed emergency heat-conducting rods 41, and a heat-conducting column 43 is slidably connected inside the emergency heat-conducting rod 41. An emergency deformation strip 42 is fixedly connected to the inner wall of the emergency heat-conducting rod 41, and one end of the emergency deformation strip 42 is connected to the heat-conducting column 43. The detection protection ring 21 is inlaid with a plurality of evenly distributed insulation frames 45, and a pair of mutually symmetrical slide cylinders 46 are inlaid in the insulation frame 45. A slide rod 47 is slidably connected inside the slide cylinder 46. The inner wall of the slide cylinder 46 is fixedly connected to a night deformation strip 48, and one end of the night deformation strip 48 is fixedly connected to the slide rod 47.

[0038] An arc-shaped insulation plate 44 is slidably connected to the insulation frame 45, and the arc-shaped insulation plate 44 is fixedly connected to the sliding rod 47. The sliding rod 47 passes through the arc-shaped insulation plate 44, and a heat conducting plate 49 is fixedly connected to the insulation frame 45. A phase change energy storage block 50 is arranged in the cavity formed by the insulation frame 45 and the heat conducting plate 49. The arc-shaped insulation plate 44 and the heat conducting plate 49 are fixedly connected to each other near one end with a plurality of evenly distributed heat conducting strips, which pass through the heat conducting plate 49 and extend into the insulation frame 45.

[0039] A centralizing column 61 is fixedly connected in the middle of the insulation frame 45, and a plurality of heat-conducting fibers are fixedly connected at both ends of the centralizing column 61. A heat-conducting film 62 is installed at the bottom end of the centralizing column 61. Heat-conducting oil 63 is arranged in the heat-conducting film 62, and a protective film 64 is fixedly connected to the outside of the heat-conducting film 62 through a plurality of flexible rods. The heat-conducting film 62 and the protective film 64 are vacuum-set.

[0040] The marking component 5 includes a transparent sphere 52 and a rupture capsule 54. The transparent sphere 52 and the rupture capsule 54 are connected. A heat-conducting support column 56 is fixedly connected to the bottom end of the transparent sphere 52. An aqueous solution 53 is set in the transparent sphere 52, a pigment is set in the rupture capsule 54, and a spike 55 is installed on the inner wall of the rupture capsule 54.

[0041] A transfer rod 51 is fixedly connected to the top of the heat-conducting ring 13 . A heat-insulating sleeve is installed around the transfer rod 51 . The transfer rod 51 passes through the heat-conducting support column 56 and extends into the interior thereof.

[0042] An extrusion block 58 is slidably connected to the transmission rod 51 , and an inspection deformation strip 57 is fixedly connected to the top end of the transmission rod 51 . The top end of the inspection deformation strip 57 is fixedly connected to the bottom end of the extrusion block 58 .

[0043] Among them, this high-temperature resistant cable that operates stably in high-temperature environments proposes a comprehensive thermal management solution that combines multi-stage heat dissipation, automatic spacing adjustment, phase change energy storage assisted cooling and visual early warning to address the problems of existing cables that have difficulty in heat dissipation at the contact surfaces of multiple cables when operating at high temperatures or large loads, local hot spots are easily formed, and there is a lack of active adjustment and emergency cooling capabilities.

[0044] The device includes a cable protective cover 1 and a monitoring protection component 2 installed on its periphery. The periphery of the cable protective cover 1 is evenly inlaid with multiple heat dissipation blocks, and multiple detection protection rings 21 are installed on its outer surface. The detection protection rings 21 can support and lift the entire cable protective cover 1, thereby increasing the contact area with the outside air, and cooperating with the heat dissipation blocks to achieve conventional natural convection and radiation heat dissipation, effectively reducing the temperature rise of the cable during normal operation.

[0045] Multiple outer cables 12 are evenly arranged inside the cable protective cover 1, and the inner cable 11 is surrounded by the outer cable 12. Multiple heat-conducting rings 13 are evenly fixed on the outer periphery of the inner cable 11, and multiple thermal expansion blocks are installed at intervals on the outside of the heat-conducting ring 13. When the temperature at the contact point of the inner and outer cables rises, the heat is first transferred to the heat-conducting ring 13 through multiple heat-conducting rods 14. The heat-conducting ring 13 conducts the heat to the adjacent thermal expansion blocks, causing the volume expansion of its material, actively expanding the distance between the inner cable 11 and the outer cable 12, reducing the direct contact heat transfer path, and at the same time forming tiny air channels locally, thereby further improving the natural convection heat dissipation efficiency on the basis of conventional heat dissipation and reducing the risk of hot spot accumulation.

[0046] The heat-conducting ring 13 is also fixedly connected to a plurality of evenly distributed transfer rods 32, which further transfer heat to the L-shaped heat-conducting block 33 installed inside the detection protection ring 21. A plurality of Z-shaped heat dissipation holes 31 are evenly opened on the outside of the detection protection ring 21, and a breathable waterproof membrane is provided in the heat dissipation holes, which can not only promote air circulation when the heat dissipation holes are opened, but also prevent rainwater from seeping in. The lower end of the L-shaped heat-conducting block 33 is connected to the slider 36 in the feedback groove 34 through the feedback bar 35. When the temperature continues to rise, the feedback bar 35 is deformed by heat, driving the slider 36 to move upward, thereby pushing the heat dissipation holes 31 to open, forming a forced convection channel, so that the heat inside the cable protective cover 1 can be quickly discharged to the outside air, realizing the first stage of active heat dissipation function.

[0047] When external natural heat dissipation and the first-stage active heat dissipation are still insufficient to control the cable temperature, the temperature will rise further. At this time, the heat-conducting ring 13 transfers the heat to the emergency heat-conducting rod 41. The emergency deformation strip 42 in the emergency heat-conducting rod 41 deforms under high temperature, pushing the heat-conducting column 43 to move toward the protective film 64. The protective film 64 and the heat-conducting film 62 originally maintain a vacuum isolation state to prevent the phase change energy storage block 50 from releasing stored energy in advance. Only after the heat-conducting column 43 squeezes the protective film 64 can the heat be transferred to the heat-conducting film 62 and the heat-conducting oil 63 inside it, and then through the concentrating column 61 and the heat-conducting fibers at both ends, the heat is quickly distributed to the phase change energy storage block 50 in the insulation frame 45. The phase change energy storage block 50 uses a high thermal conductivity phase change material and can absorb a large amount of heat during the phase change process, thereby achieving emergency rapid cooling at extreme temperatures, effectively preventing the cable from being aged or damaged due to overheating.

[0048] When the temperature triggers emergency heat dissipation, the heat is also transferred to the maintenance deformation bar 57, causing it to push the extrusion block 58 downward. The spike 55 at the bottom end of the extrusion block 58 pierces the rupture capsule 54, causing the pigment in the rupture capsule 54 to be released into the aqueous solution 53 in the transparent sphere 52. The color of the liquid then changes significantly. The color change of the marking component 5 can be identified through manual visual inspection, drone aerial photography or remote monitoring cameras, providing an intuitive visual prompt of the fault location, greatly improving operation and maintenance efficiency and safety.

[0049] In addition, this design also arranges a nighttime cold storage structure in the insulation frame 45. When the ambient temperature drops at night, the nighttime deformation strip 48 will drive the slide rod 47 to move the arc-shaped insulation plate 44, and then drive multiple heat-conducting strips connected to the heat-conducting plate 49 to transfer energy with the phase change energy storage block 50, so that the phase change material releases residual heat during the day and absorbs cold energy at night, realizing the "cold storage" process. The stored cold energy can be quickly released during the high temperature or emergency heat dissipation stage of the next day, providing additional cooling capacity for the cable system, and forming a passive circulation heat dissipation mechanism driven by the day and night temperature difference.

[0050] It should be noted that the feedback strip 35, the emergency deformation strip 42, the night deformation strip 48 and the maintenance deformation strip 57 are all made of shape memory alloy, and different deformation temperature ranges are set according to the operating safety temperature classification of the cable to achieve staged temperature control response. Among them, the deformation starting temperature of the feedback strip 35 is set to 65℃~75℃, and the complete deformation temperature is about 80℃, which is used to open the heat dissipation hole 31 in time when the cable temperature is in the early stage of overheating, enhance convection heat dissipation, and prevent hot spots from continuing to accumulate; the deformation starting temperature of the emergency deformation strip 42 is set to 90℃~95℃, and the complete deformation temperature is about 100℃~105℃, which is used to push the heat-conducting column 43 to extrude the protective film when the cable temperature approaches the limit 64, start the phase change energy storage block 50 for emergency cooling; the deformation starting temperature of the maintenance deformation strip 57 is also set to 90℃~95℃, and the complete deformation temperature is about 100℃~105℃. In the high-temperature triggering stage, the extrusion block 58 is pushed to puncture the rupture capsule 54, releasing the pigment into the aqueous solution 53 in the transparent sphere 52, to achieve a visual early warning of temperature anomalies. The deformation trigger temperature of the night deformation strip 48 is set to 15℃~20℃, and the complete deformation temperature is about 10℃~12℃, which is used to drive the slide rod 47 to drive the arc-shaped insulation plate 44 and the heat conduction plate 49 to cooperate in the low temperature environment at night, so that the phase change energy storage block 50 releases residual heat during the day and absorbs cold air at night, providing an additional cold source for high-temperature operation during the day.

[0051] For some key components, the following materials and parameters can be preferably used:

[0052] The heat conducting ring 13, heat conducting rod 14, heat conducting plate 49 and heat conducting strip are made of high thermal conductivity aluminum alloy (thermal conductivity ≥ 200 W / m·K) or copper (thermal conductivity ≥ 380 W / m·K) to improve the heat transfer efficiency; the thermal expansion block is made of a material with a thermal expansion coefficient of not less than 120× / K polymer composite material, which can produce significant deformation at 70℃~80℃; the feedback strip 35, emergency deformation strip 42, night deformation strip 48 and maintenance deformation strip 57 are all made of nickel-titanium shape memory alloy, and different deformation starting temperatures and complete deformation temperatures are set according to the cable operation safety temperature classification; the phase change energy storage block 50 adopts a paraffin-based or salt hydrate composite phase change material with a phase change temperature of 90℃±2℃ and a phase change latent heat of not less than 150 kJ / kg; the breathable and waterproof membrane uses a PTFE microporous membrane with an air permeability of ≥3000 g / m²·24h and a waterproof grade of not less than IPX6.

[0053] Through the above-mentioned graded deformation temperature setting, the high-temperature resistant cable can trigger conventional heat dissipation, emergency heat dissipation and alarm prompts in sequence within different temperature ranges, avoiding false triggering and extending the service life of the phase change energy storage block 50, thereby ensuring the long-term stable operation of the cable in a high-temperature environment.

[0054] Working principle:

[0055] First, by relying on the heat dissipation blocks evenly arranged on the periphery of the cable protective sleeve 1 and the supporting effect of the detection protection ring 21, a gap is formed between the whole and the outside air, and conventional heat dissipation is achieved through natural convection and radiation; when the temperature of the contact surface between the multiple outer cables 12 and the inner cable 11 inside the cable rises, the heat is transferred to the heat-conducting ring 13 through the heat-conducting rod 14, and further conducted to the heat expansion block on the periphery, causing the heat expansion block material to expand, actively stretching the distance between the inner cable 11 and the outer cable 12, reducing the direct contact heat transfer path and forming an air channel to enhance heat dissipation; at the same time, the heat-conducting ring 13 transfers heat to the L-shaped heat-conducting block 33 through the transfer rod 32, driving the feedback strip 35 connected to it to deform due to heat, pushing the slider 36 in the feedback groove 34 to move upward, thereby opening the heat dissipation hole 31 on the detection protection ring 21, and forming a forced convection channel under the protection of the breathable and waterproof membrane, thereby accelerating the discharge of internal heat; if the above heat dissipation measures are still not enough to control the temperature rise, the heat will continue to The heat is transmitted to the emergency heat-conducting rod 41, triggering the emergency deformation strip 42 therein to push the heat-conducting column 43 to squeeze the protective film 64, so that the protective film 64 contacts the heat-conducting film 62. The heat is quickly transmitted to the phase change energy storage block 50 in the insulation frame 45 through the heat-conducting oil 63, the concentrating column 61 and the heat-conducting fiber. The phase change material absorbs a large amount of heat during the phase change process, thereby achieving emergency rapid cooling. At the same time, part of the heat will act on the maintenance deformation strip 57, pushing the extrusion block 58 to puncture the rupture capsule 54, so that the pigment is released into the aqueous solution 53 in the transparent sphere 52. The color change serves as a visual alarm signal of temperature anomaly for manual or remote monitoring and identification. In addition, in the low temperature environment at night, the night deformation strip 48 drives the slide rod 47 to move the arc-shaped insulation plate 44, so that the heat-conducting plate 49 and the heat-conducting strip are in full contact with the phase change energy storage block 50, releasing residual heat during the day and absorbing cold at night, providing an additional cold source for high-temperature operation during the day, and realizing passive auxiliary heat dissipation in a day and night cycle.
