Description

Technical Field

[0001] The present invention relates to an overhead insulated cable, in particular to an overhead insulated cable for a smart grid applied in the field of cable technology. Background Art

[0002] The rapid development of smart grids is placing higher demands on the safety, reliability, and intelligence of transmission lines. Overhead insulated cables, as a crucial component of distribution networks, are widely used in urban and rural areas, as well as in special environments (such as areas with high salt fog and dense trees). Compared to traditional bare conductors, they offer advantages such as superior insulation, strong short-circuit resistance, and easy installation and maintenance.

[0003] Overhead insulated cables are usually laid overhead and are easily affected by wind and sway, especially in areas where typhoons and strong winds are frequent. The violent swinging of the cables may cause collisions or friction between adjacent cables, which can easily lead to safety hazards such as insulation wear, phase short circuits, and even broken wires.

[0004] Chinese patent publication number CN218216620U discloses a wind-resistant overhead insulated cable. The patent prevents multiple cables from colliding with each other during swinging by arranging a first cable, a second cable, and a third cable side by side, and then placing a wind-resistant clamp on the periphery of the second cable.

[0005] Chinese patent publication number CN111668790B discloses a cable spacer that helps mitigate the vibration of high-altitude cables. It can adapt to and alleviate various cable vibration modes, including high-frequency, slight-amplitude breeze vibration, medium-frequency, medium-amplitude sub-span vibration, and low-frequency, large-amplitude dancing.

[0006] While existing solutions can prevent cable collisions caused by swinging cables, these solutions generally have significant limitations. They lack intelligent adjustment based on wind speed and maintain high losses at low wind speeds, which can lead to excessive wear of mechanical components, potentially leading to functional failure and insufficient reliability. Therefore, we propose an overhead insulated cable for smart grids. Summary of the Invention

[0007] In response to the above-mentioned prior art, the technical problem to be solved by the present invention is: the solution in the prior art for preventing cables from colliding due to swinging cannot be intelligently adjusted according to the wind speed, and still maintains a high-loss mode at low wind speeds, which easily leads to excessive wear of mechanical components and insufficient reliability.

[0008] To solve the above problems, the present invention provides an overhead insulated cable for a smart grid, comprising two adjacent cable bodies and an intelligent anti-sway assembly. The intelligent anti-sway assembly comprises two connecting sleeves fixedly mounted on the two cable bodies, support plates fixedly mounted on the connecting sleeves, and an anti-sway damping cylinder and a damping slide rod fixedly mounted on the two support plates, respectively. A damping plate slidably and sealedly connected to the anti-sway damping cylinder is provided within the anti-sway damping cylinder, one end of the damping slide rod penetrates the outer wall of the anti-sway damping cylinder and extends to be fixedly connected to the damping plate, and the damping slide rod is slidably and sealedly connected to the outer wall of the anti-sway damping cylinder. A pressure regulating cylinder is provided above the anti-sway damping cylinder, and a pair of air guide pipes are provided on the outer wall of the top end of the anti-sway damping cylinder. The pair of air guide pipes are respectively located on the left and right sides of the damping plate. The end of the air guide pipe away from the anti-sway damping cylinder is connected to the pressure regulating cylinder. An electric telescopic rod is fixedly installed on the inner wall of the top end of the pressure regulating cylinder. The output end of the electric telescopic rod is fixedly connected to the pressure regulating plate which is slidingly and sealingly connected to the pressure regulating cylinder. A wind speed sensor is fixedly installed on the outer wall of the pressure regulating cylinder. The intelligent anti-sway component also includes an intelligent control system, which includes an intelligent setting module and a mode switching module. The intelligent setting module and the wind speed sensor are both connected to the mode switching module signal, and the mode switching module is connected to the electric telescopic rod signal.

[0009] In the above-mentioned overhead insulated cables for smart grids, the intelligent anti-sway components can not only effectively avoid collisions between adjacent cable bodies, but also effectively reduce the swing amplitude of the cable bodies. In addition, the intelligent anti-sway components can also intelligently switch between different modes according to the wind speed, effectively reducing the wear of components such as damping slide rods and damping plates, thereby ensuring the reliability of the intelligent anti-sway components.

[0010] As a further improvement of the present application, the intelligent adjustment anti-sway component has two operating modes: weak wind damage protection mode and strong wind anti-sway mode. The intelligent adjustment setting module is used to set the die cutting wind speed threshold and die cutting distance parameters. The wind speed sensor is used to collect real-time wind speed. The mode switching module is used to switch the operating mode of the intelligent adjustment anti-sway component according to the die cutting wind speed threshold and the real-time wind speed.

[0011] As a further improvement of the present application, when the real-time wind speed is not lower than the die-cutting wind speed threshold, the intelligent anti-sway component operates in a strong wind anti-sway mode.

[0012] As a further improvement of the present application, when the real-time wind speed is lower than the die-cutting wind speed threshold, the mode switching module controls the electric telescopic rod to drive the pressure regulating plate to move downward, and the moving distance is equal to the die-cutting distance parameter, so as to switch the operating mode of the intelligent anti-sway component to the weak wind loss protection mode.

[0013] As a further improvement of the present application, the intelligent adjustment setting module is also used to set the resistance adjustment wind speed threshold and the resistance adjustment distance parameter. The resistance adjustment wind speed threshold is greater than the die cutting wind speed threshold, and the resistance adjustment distance parameter is less than the die cutting distance parameter. In the strong wind anti-sway mode, when the real-time wind speed is higher than the resistance adjustment wind speed threshold, the mode switching module will control the electric telescopic rod to drive the pressure regulating plate to move downward, and the moving distance is equal to the die cutting distance parameter.

[0014] As another improvement of the present application, two air pressure sensors are further provided in the anti-sway damping cylinder, and the two air pressure sensors are respectively located on the left and right sides of the damping plate. The intelligent adjustment control system also includes an air pressure analysis module and a remote alarm module. The air pressure sensor, the intelligent adjustment setting module, and the mode switching module are all connected to the air pressure analysis module signal, and the air pressure analysis module is connected to the remote alarm module signal. The intelligent adjustment setting module is also used to set the air pressure threshold and resistance adjustment distance parameters, and the mode switching module is connected to the air pressure sensor signal.

[0015] As another improvement supplement to the present application, the air pressure sensor is used to collect real-time air pressure. In the strong wind anti-sway mode, when the real-time air pressure is greater than the air pressure threshold, the air pressure analysis module will control the remote alarm module to issue an alarm.

[0016] As another improvement supplement to the present application, a detection electromagnet is provided in the anti-sway damping cylinder, and the end of the damping plate away from the damping slide rod is fixedly connected to a fixed plate magnet. The detection electromagnet is located on the side of the fixed plate magnet away from the damping slide rod, and an electromagnetic valve is provided on the air duct on the side of the damping plate away from the damping slide rod. The intelligent adjustment control system also includes an airtightness detection module.

[0017] As another improvement supplement to the present application, the intelligent adjustment setting module and the mode switching module are both signal-connected to the airtightness detection module, and the airtightness detection module is signal-connected to the electric telescopic rod, air pressure sensor, detection electromagnet, solenoid valve, and remote alarm module.

[0018] In summary, the present application sets up the intelligent anti-swing component, so that in windy weather, the intelligent anti-swing component can not only effectively avoid collisions between adjacent cable bodies, but also effectively reduce the swing amplitude of the cable body, greatly improving the safety of the cable, and the intelligent anti-swing component can also intelligently switch different modes according to the size of the wind speed, thereby effectively reducing the wear of components such as the damping slide rod and the damping plate while ensuring the safety of the cable, thereby effectively extending the service life of the intelligent anti-swing component and ensuring the reliability of the intelligent anti-swing component. In addition, the intelligent anti-swing component can also intelligently adjust the damping effect according to the wind speed, further The safety of the cable is further improved; when the swing amplitude of the cable body is too large, the air pressure analysis module will control the remote alarm module to sound an alarm, which can prompt relevant technical personnel to conduct corresponding inspections on the cable, thereby further improving the safety of the cable; through the joint setting of air pressure sensors, detection electromagnets, airtightness detection modules, etc., it is possible to automatically detect the airtightness between the components in the intelligent anti-swing assembly, and can issue an alarm when airtightness problems are detected, so that relevant technical personnel can discover and solve problems in time, which not only improves the reliability of the intelligent anti-swing assembly, but also further improves the safety of the cable.

DETAILED DESCRIPTION

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method: Figure 1-Figure 5 An overhead insulated cable for a smart grid is shown, comprising two adjacent cable bodies 001 and an intelligent anti-sway assembly. The intelligent anti-sway assembly comprises two connecting sleeves 201 fixedly mounted on the two cable bodies 001, each with a support plate 202 fixedly mounted on the connecting sleeve 201. An anti-sway damping cylinder 203 and a damping slide 204 are respectively fixedly mounted on the two support plates 202. A damping plate 205 is provided within the anti-sway damping cylinder 203, in sliding and sealing connection therewith. One end of the damping slide 204 penetrates the outer wall of the anti-sway damping cylinder 203 and extends to be fixedly connected to the damping plate 205. The damping slide 204 is also in sliding and sealing connection with the outer wall of the anti-sway damping cylinder 203. A pressure regulating cylinder 206 is provided above the anti-sway damping cylinder 203. A pair of air guide tubes 207 are provided on the outer wall of the top end of the anti-sway damping cylinder 203. The pair of air guide tubes 207 are respectively located on the left and right sides of the damping plate 205. The end of the air guide tube 207 away from the anti-sway damping cylinder 203 is connected to the pressure regulating cylinder 206. An electric telescopic rod 208 is fixedly mounted on the inner wall of the top end of the pressure regulating cylinder 206. The output end of the electric telescopic rod 208 is fixedly connected to a pressure regulating plate 209 that is slidably and hermetically connected to the pressure regulating cylinder 206. A wind speed sensor 210 is fixedly mounted on the outer wall of the pressure regulating cylinder 206. The intelligent adjustment anti-sway component also includes an intelligent adjustment control system, which includes an intelligent adjustment setting module and a mode switching module. The intelligent adjustment setting module and the wind speed sensor 210 are both connected to the mode switching module signal, and the mode switching module is connected to the electric telescopic rod 208 signal.

[0023] The intelligent adjustment anti-swing component has two operating modes: weak wind loss protection mode and strong wind anti-swing mode. The intelligent adjustment setting module is used to set the die cutting wind speed threshold and die cutting distance parameters. The wind speed sensor 210 is used to collect real-time wind speed. The wind speed data collected by the wind speed sensor 210 will be transmitted to the mode switching module in real time. The mode switching module is used to switch the operating mode of the intelligent adjustment anti-swing component according to the die cutting wind speed threshold and the real-time wind speed. When the real-time wind speed is not lower than the die cutting wind speed threshold, the intelligent adjustment anti-swing component operates in strong wind anti-swing mode. In this mode, when the two cables 001 swing in the direction of approaching each other, the damping slide bar 204 will slide into the anti-sway damping cylinder 203, causing the damping plate 205 to squeeze the air on its right side (the side away from the damping slide bar 204). The squeezed air can provide a damping effect, which can not only effectively avoid collision between the two cable bodies 001, but also effectively reduce the swing amplitude of the cable body 001. In addition, when the two cable bodies 001 swing away from each other, the damping slide bar 204 will slide out of the anti-sway damping cylinder 203, causing the damping plate 205 to squeeze the air on its left side (the side close to the damping slide bar 204), thereby also effectively reducing the swing amplitude of the cable body 001.

[0024] When the real-time wind speed is lower than the die-cutting wind speed threshold, the mode switching module controls the electric telescopic rod 208 to drive the pressure regulating plate 209 to move downward, and the moving distance is equal to the die-cutting distance parameter, so as to switch the operation mode of the intelligent anti-sway component to the weak wind loss protection mode. When the electric telescopic rod 208 drives the pressure regulating plate 209 to move downward, the pressure regulating plate 209 will squeeze the air below it, causing part of the air to flow into the anti-sway damping cylinder 203 through the air guide pipe 207, thereby significantly increasing the air pressure on the left and right sides of the damping plate 205. The increase in air pressure will limit the movement of the damping plate 205, making it difficult for the damping plate 205 to slide. Therefore, in the weak wind loss protection mode, the sliding frequency of the damping slide rod 204 and the damping plate 205 will be significantly reduced, thereby effectively reducing the wear of the damping slide rod 204, the damping plate 205, etc. Since the wind speed is relatively low (that is, when the real-time wind speed is lower than the die-cutting wind speed threshold), the impact of the wind on the cable is relatively small, which will only cause the cable to swing slightly. Even if The safety of the cable can be guaranteed without intervention. Therefore, when the wind speed is low, the weak wind loss protection mode is started, which can not only ensure the safety of the cable, but also reduce the wear of components. When the wind speed rises to greater than or equal to the cutting wind speed threshold, the mode switching module will control the electric telescopic rod 208 to drive the pressure regulating plate 209 to move upward and reset to switch the mode back to the strong wind anti-swing mode. Therefore, through the setting of the intelligent anti-swing component, in windy weather, the intelligent anti-swing component can not only effectively avoid collisions between adjacent cable bodies 001, but also effectively reduce the swing amplitude of the cable body 001, greatly improving the safety of the cable, and the intelligent anti-swing component can also intelligently switch different modes according to the wind speed, thereby effectively reducing the wear of components such as the damping slide rod 204 and the damping plate 205 while ensuring the safety of the cable, thereby effectively extending the service life of the intelligent anti-swing component and ensuring the reliability of the intelligent anti-swing component, further improving the safety of the cable.

[0025] The intelligent adjustment setting module is also used to set the resistance adjustment wind speed threshold and resistance adjustment distance parameters. The resistance adjustment wind speed threshold is greater than the die cutting wind speed threshold, and the resistance adjustment distance parameter is less than the die cutting distance parameter. In the strong wind anti-swing mode, when the real-time wind speed is higher than the resistance adjustment wind speed threshold, the mode switching module will control the electric telescopic rod 208 to drive the pressure regulating plate 209 to move downward, and the moving distance is equal to the die cutting distance parameter. In this way, the damping effect can be enhanced, thereby further reducing the swing amplitude of the cable body 001, so that the intelligent anti-swing component can also intelligently adjust the damping effect according to the wind speed, further improving the safety of the cable.

[0026] The second implementation method: Figure 6-Figure 8An overhead insulated cable for a smart grid is shown. Unlike the first embodiment, two air pressure sensors 301 are also provided in the anti-sway damping cylinder 203. The two air pressure sensors 301 are respectively located on the left and right sides of the damping plate 205. The intelligent adjustment control system also includes an air pressure analysis module and a remote alarm module. The air pressure sensor 301, the intelligent adjustment setting module, and the mode switching module are all connected to the air pressure analysis module signal. The air pressure analysis module is connected to the remote alarm module signal. The intelligent adjustment setting module is also used to set the air pressure threshold and resistance adjustment distance parameters. The mode switching module is connected to the air pressure sensor 301 signal (when the mode switching module switches the mode to the strong wind anti-sway mode, the air pressure sensor 301 will be started, and when the mode switching module switches the mode to the weak wind loss protection mode, the air pressure sensor 301 will be turned off).

[0027] The air pressure sensor 301 is used to collect real-time air pressure. The air pressure data collected by the air pressure sensor 301 will be transmitted to the air pressure analysis module in real time. In the strong wind anti-sway mode, when the real-time air pressure is greater than the air pressure threshold, the air pressure analysis module will control the remote alarm module to issue an alarm (remote alarm is an existing technology and will not be described here). The greater the swing amplitude of the cable body 001, the greater the degree of compression of the air by the damping plate 205, the greater the air pressure on the corresponding side, and the greater the real-time air pressure detected by the corresponding air pressure sensor 301. When the real-time air pressure is greater than the air pressure threshold, it means that the swing amplitude of the cable body 001 is too large, and there may be some abnormality. At this time, the air pressure analysis module controls the remote alarm module to issue an alarm, which can prompt relevant technical personnel to conduct corresponding inspections on the cable, thereby further improving the safety of the cable.

[0028] A detection electromagnet 302 is provided in the anti-sway damping cylinder 203, and a fixed plate magnet 303 is fixedly connected to the end of the damping plate 205 away from the damping slide rod 204. The detection electromagnet 302 is located on the side of the fixed plate magnet 303 away from the damping slide rod 204, and a solenoid valve 304 is provided on the air guide tube 207 located on the side of the damping plate 205 away from the damping slide rod 204. The intelligent adjustment control system also includes an airtight detection module. The intelligent adjustment setting module and the mode switching module are both signal-connected to the airtight detection module. The airtight detection module is signal-connected to the electric telescopic rod 208, the air pressure sensor 301, the detection electromagnet 302, the solenoid valve 304, and the remote alarm module.

[0029] The intelligent adjustment setting module is also used to set the detection cycle and detection distance parameters. In the weak wind loss protection mode, the airtightness detection module will perform detection operations regularly according to the self-test cycle. During self-test, the airtightness detection module will close the solenoid valve 304 (the solenoid valve 304 is in the open state during the non-test period) and start the two air pressure sensors 301 (after the air pressure sensor 301 is started, the air pressure data it detects will be transmitted to the airtightness detection module in real time), and then control the electric telescopic rod 208 to drive the pressure regulating plate 209 to move downward, and the moving distance is equal to the detection distance parameter. At the same time, the airtightness detection module will also control the detection electromagnet 302 to be energized, so that the detection electromagnet 302 applies a one-side magnetic repulsion force to the fixed plate magnet 303. The downward movement of the pressure regulating plate 209 will increase the air pressure on the left side of the damping plate 205, causing the damping plate 205 to have a tendency to move to the right. However, the magnetic repulsion between the detection electromagnet 302 and the fixed plate magnet 303 will limit the movement of the damping plate 205. Therefore, the air pressure on the left side of the damping plate 205 will be greater than the air pressure on the right side. After the detection electromagnet 302 is energized and the pressure regulating plate 209 is moved, if If the air tightness between the damping plate 205 and the anti-sway damping cylinder 203, between the pressure regulating plate 209 and the pressure regulating cylinder 206, and between the damping slide bar 204 and the anti-sway damping cylinder 203 are all maintained well, then the air pressure on the left and right sides of the damping plate 205 will be relatively stable without too much fluctuation. If there is a problem with the air tightness between the pressure regulating plate 209 and the pressure regulating cylinder 206 or between the damping slide bar 204 and the anti-sway damping cylinder 203, the air pressure on the right side of the damping plate 205 will still be relatively stable, but the air pressure on the left side of the damping plate 205 will continue to drop. If there is a problem with the airtightness between the damping plate 205 and the anti-sway damping cylinder 203, the air pressure on the left side of the damping plate 205 will continue to decrease, and the air pressure on the right side of the pressure regulating cylinder 206 will continue to increase. Therefore, the airtightness detection module can determine whether there is a problem with the airtightness between the damping plate 205 and the anti-sway damping cylinder 203, between the pressure regulating plate 209 and the pressure regulating cylinder 206, and between the damping slide bar 204 and the anti-sway damping cylinder 203 by analyzing the air pressure data detected by the two air pressure sensors 301, thereby realizing automatic detection of the airtightness between the components in the intelligent anti-sway assembly; When the test result shows that there is a problem with the air tightness between two components, the air tightness detection module will control the remote alarm module to issue an alarm. After the test is completed, the air tightness detection module will open the solenoid valve 304, close the air pressure sensor 301 and the detection electromagnet 302, and control the electric telescopic rod 208 to drive the pressure regulating plate 209 to move upward and reset (the moving distance is equal to the detection distance parameter). Therefore, through the joint setting of the air pressure sensor 301, the detection electromagnet 302, the air tightness detection module, etc., it is possible to automatically detect the air tightness between the components in the intelligent anti-sway assembly, and to issue an alarm when an air tightness problem is detected, so that relevant technical personnel can discover and solve the problem in time, which not only improves the reliability of the intelligent anti-sway assembly, but also further improves the safety of the cable.

[0030] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
