Description

TECHNICAL FIELD

[0001] The present application relates to an overhead insulated cable, in particular to an overhead insulated cable for smart grid applied in the field of cable technology. BACKGROUND

[0002] With the rapid development of smart grid, higher requirements are put forward for the safety, reliability and intelligent level of power transmission lines. As an important part of the distribution network, overhead insulated cables are widely used in cities, rural areas and special environments (such as high salt fog and many trees). Compared with traditional bare wires, overhead insulated cables have the advantages of good insulation performance, strong short-circuit resistance, easy installation and maintenance, etc.

[0003] Overhead insulated cables are usually laid overhead and are easily affected by wind to swing, especially in areas where typhoons and strong winds occur frequently. The violent swinging of the cable may cause collision or friction between adjacent cables, which may lead to insulation wear, inter-phase short circuit and even wire breakage, etc.

[0004] A wind-resistant overhead insulated cable is disclosed in Chinese Patent No. CN218216620U. The patent avoids the collision of multiple cables during swinging by arranging the first cable, the second cable and the third cable side by side, and placing the wind-resistant clamp around the second cable.

[0005] Chinese Patent No. CN111668790B discloses a cable spacer for assisting in reducing the vibration of high-altitude cables, which can adapt to and alleviate various cable vibration modes such as high-frequency small-amplitude breeze vibration, medium-frequency medium-amplitude sub-span vibration and low-frequency large-amplitude galloping.

[0006] In the prior art, although there are some solutions to avoid collision of cables due to swinging, these solutions generally have great limitations and cannot be intelligently adjusted according to wind speed. They still maintain a high loss mode at low wind speed, which can easily lead to excessive wear of mechanical parts and functional failure, resulting in insufficient reliability. Therefore, we propose an overhead insulated cable for smart grid. SUMMARY

[0007] In view of the above prior art, the technical problem to be solved by the present application is that the prior art solution to avoid collision of cables due to swinging cannot be intelligently adjusted according to wind speed, and still maintains a high loss mode at low wind speed, which can easily lead to excessive wear of mechanical parts and insufficient reliability.

[0008] To address the aforementioned problems, this invention provides an overhead insulated cable for smart grids, comprising two adjacent cable bodies and an intelligent anti-sway assembly. The intelligent anti-sway assembly includes two connecting sleeves respectively fixedly fitted onto the two cable bodies. A support plate is fixedly installed on the connecting sleeves. An anti-sway damping cylinder and a damping slide rod are respectively fixedly installed on the two support plates. A damping plate is provided inside the anti-sway damping cylinder and is slidably and sealingly connected thereto. One end of the damping slide rod penetrates through the outer wall of the anti-sway damping cylinder and extends to be fixedly connected to the damping plate. The damping slide rod is slidably and sealingly connected to the outer wall of the anti-sway damping cylinder.

[0009] A pressure regulating cylinder is installed above the anti-sway damping cylinder. A pair of air guide pipes are connected to the outer wall of the top of the anti-sway damping cylinder. The pair of air guide pipes are located on the left and right sides of the damping plate, respectively. 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 of the pressure regulating cylinder. The output end of the electric telescopic rod is fixedly connected to a pressure regulating plate that is slidably sealed with the pressure regulating cylinder. A wind speed sensor is fixedly installed on the outer wall of the pressure regulating cylinder.

[0010] The intelligent adjustment and 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 are both connected to the mode switching module, and the mode switching module is connected to the electric telescopic pole.

[0011] In the aforementioned overhead insulated cables for smart grids, the intelligent anti-sway component can not only effectively prevent collisions between adjacent cables, but also effectively reduce the sway amplitude of the cable. Furthermore, the intelligent anti-sway component can intelligently switch between different modes according to the wind speed, effectively reducing the wear of components such as damping slides and damping plates, thereby ensuring the reliability of the intelligent anti-sway component.

[0012] As a further improvement of this application, the intelligent adjustment anti-sway component has two operating modes: a weak wind loss protection mode and a strong wind anti-sway mode. The intelligent adjustment setting module is used to set the cutting wind speed threshold and cutting distance parameters, the wind speed sensor is used to collect real-time wind speed, and the mode switching module is used to switch the operating mode of the intelligent adjustment anti-sway component according to the cutting wind speed threshold and the real-time wind speed.

[0013] As a further improvement to this application, when the real-time wind speed is not lower than the cutting wind speed threshold, the intelligent anti-sway component operates in strong wind anti-sway mode.

[0014] As a further improvement of this application, when the real-time wind speed is lower than the cutting wind speed threshold, the mode switching module controls the electric telescopic rod to drive the pressure regulating plate to move downward. The distance moved is equal to the cutting distance parameter, so as to switch the operation mode of the intelligent adjustment anti-sway component to the weak wind loss protection mode.

[0015] As a further improvement of this application, the intelligent adjustment setting module is also used to set the damping wind speed threshold and the damping distance parameter. The damping wind speed threshold is greater than the cutting wind speed threshold, and the damping distance parameter is less than the cutting distance parameter. In the strong wind anti-sway mode, when the real-time wind speed is higher than the damping 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 cutting distance parameter.

[0016] As another improvement of this application, two air pressure sensors are also provided inside the anti-sway damping cylinder. The two air pressure sensors are located on the left and right sides of the damping plate, respectively. The intelligent adjustment control system also includes an air pressure analysis module and a remote alarm module. The air pressure sensors, intelligent adjustment setting module, and mode switching module are all connected to the air pressure analysis module. The air pressure analysis module is connected to the remote alarm module. The intelligent adjustment setting module is also used to set the air pressure threshold and adjustment distance parameters. The mode switching module is connected to the air pressure sensor.

[0017] As a supplement to another improvement in this application, the barometric pressure sensor is used to collect real-time barometric pressure. In strong wind anti-sway mode, when the real-time barometric pressure is greater than the barometric pressure threshold, the barometric pressure analysis module will control the remote alarm module to issue an alarm.

[0018] As a supplement to another improvement of this application, a detection electromagnet is provided inside the anti-sway damping cylinder, a fixed plate magnet is fixedly connected to the end of the damping plate away from the damping slide rod, the detection electromagnet is located on the side of the fixed plate magnet away from the damping slide rod, and a solenoid valve is provided on the air guide pipe located on the side of the damping plate away from the damping slide rod. The intelligent adjustment control system also includes an airtightness detection module.

[0019] As a supplement to another improvement in this application, the intelligent adjustment setting module and the mode switching module are both connected to the air tightness detection module by signal, and the air tightness detection module is also connected to the electric telescopic rod, the air pressure sensor, the detection electromagnet, the solenoid valve, and the remote alarm module by signal.

[0020] In summary, this application, through the installation of an intelligent anti-sway component, effectively prevents collisions between adjacent cables during windy weather and significantly reduces cable sway amplitude, greatly improving cable safety. Furthermore, the intelligent anti-sway component can intelligently switch between different modes based on wind speed, thereby effectively reducing wear on components such as damping rods and damping plates while ensuring cable safety. This extends the service life of the intelligent anti-sway component and ensures its reliability. Additionally, the intelligent anti-sway component can intelligently adjust the damping effect according to wind speed, further enhancing its performance. This design enhances cable safety. When the cable swings excessively, the air pressure analysis module controls the remote alarm module to issue an alarm, prompting relevant technicians to inspect the cable and further improving its safety. Through the combined use of air pressure sensors, detection electromagnets, and airtightness detection modules, the airtightness between components in the intelligent anti-sway assembly can be automatically detected, and an alarm can be issued when an airtightness problem is detected. This allows relevant technicians to promptly identify and resolve issues, improving not only the reliability of the intelligent anti-sway assembly but also the overall safety of the cable.

[0031] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] First implementation method:

[0033] Figures 1-5 An overhead insulated cable for a smart grid is shown, comprising two adjacent cable bodies 001 and an intelligent adjustment and anti-sway assembly. The intelligent adjustment and anti-sway assembly includes two connecting sleeves 201 respectively fixedly sleeved on the two cable bodies 001. A support plate 202 is fixedly installed on the connecting sleeve 201. An anti-sway damping cylinder 203 and a damping slide rod 204 are fixedly installed on the two support plates 202 respectively. A damping plate 205 is provided inside the anti-sway damping cylinder 203 and is slidably and sealed to it. One end of the damping slide rod 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 rod 204 is slidably and sealed to the outer wall of the anti-sway damping cylinder 203.

[0034] A pressure regulating cylinder 206 is provided above the anti-sway damping cylinder 203. A pair of air guide pipes 207 are connected to the outer wall of the top of the anti-sway damping cylinder 203. The pair of air guide pipes 207 are located on the left and right sides of the damping plate 205 respectively. The end of the air guide pipe 207 away from the anti-sway damping cylinder 203 is connected to the pressure regulating cylinder 206. An electric telescopic rod 208 is fixedly installed on the inner wall of the top 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 sealed to the pressure regulating cylinder 206. A wind speed sensor 210 is fixedly installed on the outer wall of the pressure regulating cylinder 206.

[0035] The intelligent adjustment and 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, and the mode switching module is connected to the electric telescopic pole 208.

[0036] The intelligent anti-sway component has two operating modes: a weak wind loss protection mode and a strong wind anti-sway mode. The intelligent adjustment setting module is used to set the cutting wind speed threshold and 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 is transmitted to the mode switching module in real time. The mode switching module is used to switch the operating mode of the intelligent anti-sway component according to the cutting wind speed threshold and the real-time wind speed. When the real-time wind speed is not lower than the cutting wind speed threshold, the intelligent anti-sway component operates in the strong wind anti-sway mode. In this mode, when the two cables 001 swing in the direction of approach, the damping slide bar... 204 will slide into the anti-sway damping cylinder 203, causing the damping plate 205 to compress the air on its right side (the side away from the damping slide bar 204). The compressed air provides a damping effect, which can not only effectively prevent the collision between the two cables 001, but also effectively reduce the swing amplitude of the cable 001. In addition, when the two cables 001 swing in opposite directions, the damping slide bar 204 will slide out of the anti-sway damping cylinder 203, causing the damping plate 205 to compress the air on its left side (the side closer to the damping slide bar 204), which can also effectively reduce the swing amplitude of the cable 001.

[0037] When the real-time wind speed is lower than the cutting speed threshold, the mode switching module controls the electric telescopic rod 208 to move the pressure regulating plate 209 downwards. The distance moved is equal to the cutting distance parameter, switching the operating mode of the intelligent anti-sway component to the weak wind protection mode. When the electric telescopic rod 208 moves the pressure regulating plate 209 downwards, the pressure regulating plate 209 will compress the air below it, causing some air to flow into the anti-sway damping cylinder 203 through the air duct 207. This significantly increases the air pressure on both sides of the damping plate 205. The increased air pressure restricts the movement of the damping plate 205, making it difficult for the damping plate 205 to slide. Therefore, in the weak wind protection mode, the sliding frequency of the damping slide rod 204 and the damping plate 205 will be significantly reduced, effectively reducing the wear of the damping slide rod 204 and the damping plate 205. Since the wind speed is low (i.e., the real-time wind speed is lower than the cutting speed threshold), the wind has little impact on the cable, only causing the cable to sway slightly. The safety of the cable can be guaranteed without intervention. Therefore, when the wind speed is low, the weak wind protection mode is activated, which can not only ensure the safety of the cable, but also reduce the wear of components. When the wind speed rises to a level greater than or equal to the cutting wind speed threshold, the mode switching module will control the electric telescopic rod 208 to drive the voltage regulating plate 209 to move upward and reset, so as to switch the mode back to the strong wind anti-sway mode. Therefore, through the setting of the intelligent anti-sway component, in windy weather, the intelligent anti-sway component can not only effectively avoid collisions between adjacent cable bodies 001, but also effectively reduce the swing amplitude of cable body 001, which greatly improves the safety of the cable. Moreover, the intelligent anti-sway 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. This can effectively extend the service life of the intelligent anti-sway component and ensure its reliability, further improving the safety of the cable.

[0038] The intelligent adjustment setting module is also used to set the damping wind speed threshold and damping distance parameter. The damping wind speed threshold is greater than the cutting wind speed threshold, and the damping distance parameter is less than the cutting distance parameter. In the strong wind anti-sway mode, when the real-time wind speed is higher than the damping wind speed threshold, the mode switching module will control the electric telescopic rod 208 to drive the pressure regulating plate 209 to move downward. The distance moved is equal to the cutting distance parameter. In this way, the damping effect can be enhanced, thereby further reducing the swing amplitude of the cable 001. The intelligent adjustment anti-sway component can also intelligently adjust the damping effect according to the wind speed, further improving the safety of the cable.

[0039] Second implementation method:

[0040] Figures 6-8This invention illustrates an overhead insulated cable for a smart grid. Unlike the first embodiment, the anti-sway damping cylinder 203 is equipped with two air pressure sensors 301, which are located on the left and right sides of the damping plate 205, respectively. The intelligent adjustment control system also includes an air pressure analysis module and a remote alarm module. The air pressure sensors 301, the intelligent adjustment setting module, and the mode switching module are all connected to the air pressure analysis module. The air pressure analysis module is also connected to the remote alarm module. The intelligent adjustment setting module is also used to set the air pressure threshold and the adjustment distance parameter. The mode switching module is connected to the air pressure sensor 301 (when the mode switching module switches the mode to the strong wind anti-sway mode, it will activate the air pressure sensor 301; when the mode switching module switches the mode to the weak wind loss protection mode, it will deactivate the air pressure sensor 301).

[0041] The air pressure sensor 301 is used to collect real-time air pressure. The air pressure data collected by the air pressure sensor 301 is 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 existing technology and will not be described in detail here). The greater the swing amplitude of the cable 001, the greater the degree of air compression by the damping plate 205, and the greater the air pressure on the corresponding side. The real-time air pressure detected by the corresponding air pressure sensor 301 is also greater. When the real-time air pressure is greater than the air pressure threshold, it indicates that the swing amplitude of the cable 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 technicians to conduct corresponding inspections of the cable, thereby further improving the safety of the cable.

[0042] An anti-sway damping cylinder 203 is equipped with a detection electromagnet 302. A fixed plate magnet 303 is fixedly connected to one 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. A solenoid valve 304 is installed on the air duct 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 air tightness detection module. The intelligent adjustment setting module and the mode switching module are both signal-connected to the air tightness detection module. The air tightness detection module is also 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.

[0043] 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 periodically perform detection operations 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 non-detection periods) and activate the two air pressure sensors 301 (after the air pressure sensors 301 are activated, the air pressure data detected by them will be transmitted to the airtightness detection module in real time). Then, it controls the electric telescopic rod 208 to drive the pressure regulating plate 209 to move downward. The distance moved is equal to the detection distance parameter. Simultaneously, the airtightness detection module also controls the energization of the detection electromagnet 302, causing it to apply a magnetic repulsion force to the fixed plate magnet 303 on one side. The downward movement of the pressure regulating plate 209 increases the air pressure on the left side of the damping plate 205, causing it to tend to move to the right. However, the magnetic repulsion force between the detection electromagnet 302 and the fixed plate magnet 303 restricts 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 its right side. After the detection electromagnet 302 is energized and the pressure regulating plate 209 has moved, if... If 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 rod 204 and the anti-sway damping cylinder 203 is good, then the air pressure on both sides of the damping plate 205 will be relatively stable without significant fluctuations. If there is a problem with the airtightness between the pressure regulating plate 209 and the pressure regulating cylinder 206, or between the damping slide rod 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 decrease. 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 analyze the air pressure data detected by the two air pressure sensors 301 to 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 rod 204 and the anti-sway damping cylinder 203, thereby realizing automatic detection of the airtightness between the components in the intelligent anti-sway assembly.

[0044] When the test result indicates a problem with the airtightness between two components, the airtightness detection module will control the remote alarm module to issue an alarm. After the test is completed, the airtightness 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 move the pressure regulating plate 209 upward to reset (the moving distance is equal to the detection distance parameter). Therefore, through the combined setting of the air pressure sensor 301, the detection electromagnet 302, the airtightness detection module, etc., the airtightness between the components in the intelligent adjustment anti-sway assembly can be automatically detected, and an alarm can be issued when an airtightness problem is detected. This allows relevant technicians to discover and solve problems in a timely manner, which not only improves the reliability of the intelligent adjustment anti-sway assembly, but also further improves the safety of the cable.

[0045] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
