[0001] This invention belongs to the field of power distribution network fault handling technology, and more specifically, it relates to a power distribution network fault handling method and device. Background Technology

[0002] With the rapid development of the power industry, the distribution network is becoming increasingly widespread. Due to the harsh operating environment, the distribution network is highly susceptible to failures caused by equipment aging. Because existing distribution networks span long distances and have numerous branches, traditional manual line inspection methods are not only labor-intensive and inefficient, but also consume significant human and material resources, failing to meet the needs of modern power grid inspection. When a power grid fault occurs, maintenance personnel often struggle to determine the location and type of the fault, resulting in prolonged repair times and unnecessary losses for residents, factories, and other electricity customers along the affected route. Summary of the Invention

[0003] The purpose of this invention is to provide a method and device for handling power distribution network faults, which can quickly locate the fault point, determine the fault type and repair method, effectively improve maintenance efficiency, and ensure normal power supply for residents.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a method for handling power distribution network faults, comprising the following steps:

[0005] The cable monitoring device identifies cables in the external network, generates cable fault information, and sends it to the control system.

[0006] The load operation monitoring device monitors the operation of the power distribution equipment, generates load monitoring information, and sends it to the control system.

[0007] The control system receives cable fault information and load monitoring information, and determines whether the power distribution network is a fault of the power distribution equipment or the external network line according to the preset program, and sends a restart command to the power distribution equipment or a line stabilization and fixing command to the line stabilization and fixing unit.

[0008] The power distribution equipment receives a restart command and restarts, or the line stabilization and fixing unit receives a line stabilization and fixing command and performs maintenance on the external network.

[0009] In one possible implementation, in the step where the control system receives cable fault information and load monitoring information, and determines whether the fault belongs to the power distribution equipment or the external network line according to a preset program:

[0010] If the power distribution network is in a state of power distribution equipment failure, the control system sends a restart command to the corresponding power distribution equipment;

[0011] If the distribution network is in a state of external line fault, the control system sends a maintenance command to the line stabilization and fixing unit of the corresponding tower.

[0012] In one possible implementation, the step of the load operation monitoring device monitoring the operation of the power distribution equipment, generating load monitoring information and sending it to the control system further includes the load operation monitoring device identifying the location information and equipment coding information of the power distribution equipment and sending the location information and equipment coding information to the control system.

[0013] In one possible implementation, the steps of the cable monitoring device identifying faults in the power distribution equipment, generating cable fault information, and sending it to the control system further include, when the control system determines that the power distribution network is in an external network line fault state, using a drone to conduct a review and inspection of the external network lines of the power distribution network, collecting video information of the fault points of the external network lines, and sending the video information to the control system for review.

[0014] Compared with the prior art, the power distribution network fault handling method provided in this application embodiment utilizes a cable monitoring device to monitor cables in the external network and generate line fault information to send to the control system. At the same time, a load operation monitoring device monitors the operation of multiple power distribution devices and sends load monitoring information to the control system. The control system determines whether the fault is in the power distribution device or in the external network cable based on the received information, and then issues corresponding control commands to restart the power distribution device or repair the external network line, thereby improving the timeliness of power distribution network maintenance and ensuring the stable operation of the power distribution network.

[0015] The present invention also provides a power distribution network fault handling device that utilizes a power distribution network fault handling method for fault handling. The power distribution network fault handling device includes:

[0016] Several cable monitoring devices are installed on several poles and towers, and are installed one-to-one with each pole and tower. The cable monitoring devices are installed close to the end of the cable to identify cable faults and generate cable fault information.

[0017] Several load operation monitoring devices are installed on several power distribution devices and are installed one-to-one with the power distribution devices. The load operation monitoring devices are used to identify faults in the power distribution devices and generate load monitoring information.

[0018] The control system is used to receive cable fault information and load monitoring information, and determine whether the fault is due to power distribution equipment or external network line according to the preset program, and issue a restart command or maintenance command accordingly.

[0019] Several line stabilization and fixing units are installed one-to-one on several poles and towers, and are electrically connected to the control system to receive automatic maintenance commands from the control system and to perform maintenance on the external network lines.

[0020] Specifically, when there is a fault in the power distribution equipment in the power distribution network, the control system sends a restart command to the corresponding power distribution equipment; when there is a fault in the external network line in the power distribution network, the control system sends an automatic maintenance command to the corresponding line stabilization and fixing unit so that the line stabilization and fixing unit can perform maintenance on the external network line, or sends a manual maintenance command from the control system to the equipment terminal so that maintenance personnel can perform manual maintenance on the fault point.

[0021] In one possible implementation, the power distribution network fault handling device further includes several location information sets that correspond one-to-one with the power distribution equipment and several equipment code information sets that correspond one-to-one with the power distribution equipment.

[0027] The horizontal suspension rod is slidably connected to a lateral drive component that can move along its extension direction. The lateral drive component can move toward the extended end of the horizontal suspension rod to drive the cable clamping assembly closer to the tower and tension the cable.

[0028] In one possible implementation, the lateral movement actuator includes:

[0029] The motor is connected to the bottom of the horizontal suspension bar and is located near the outer end of the horizontal suspension bar;

[0030] The lead screw is connected to the output end of the motor and extends towards one side of the tower.

[0031] The lead screw nut works in conjunction with the lead screw, and a hanging ring connected to the tension line is located below the lead screw nut;

[0032] The horizontal suspension rod is equipped with a limiting ring for limiting the tension line, and the limiting ring is located on the side of the nut closer to the tower.

[0033] In one possible implementation, the clip wire assembly includes:

[0034] A mounting block, attached to one side of the cable;

[0035] Pull the swing arm, which is rotatably connected to the lower part of the hanging block via the first rotating shaft, and extends towards the side closer to the tower;

[0036] The clamping seat is rotatably connected to the middle of the hook block via a second rotating shaft. The end of the clamping seat near the tower has a limiting collar sleeved on the outer periphery of the pulling swing arm to limit the downward swing of the pulling swing arm away from the cable. The clamping seat has a clamping surface that can abut against the bottom of the cable.

[0037] In one possible implementation, the upper part of the hook block is provided with an extension that extends to the other side of the cable, the clamping seat gradually tilts outward in an arc shape from bottom to top away from the second rotating shaft, and the cross-sectional area of ​​the clamping seat gradually increases, and a flexible pad that abuts against the cable is provided on the clamping surface.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0051] Please refer to the following: Figures 1 to 7 The present invention will now describe the power distribution network fault handling method and apparatus provided. The power distribution network fault handling method includes the following steps:

[0052] The cable monitoring device 1 identifies cable 81 in the external network, generates cable 81 fault information, and sends it to the control system 3.

[0053] The load operation monitoring device 2 monitors the operation of the power distribution equipment 6, generates load monitoring information, and sends it to the control system 3;

[0054] The control system 3 receives cable 81 fault information and load monitoring information, and determines whether the power distribution network is faulty due to power distribution equipment 6 or external network line fault according to the preset program, and sends a restart command to power distribution equipment 6 or sends a line stabilization and fixing command to line stabilization and fixing unit 4.

[0055] The power distribution equipment 6 receives the restart command and restarts, or the line stabilization and fixing unit 4 receives the line stabilization and fixing command and performs maintenance on the external network.

[0056] Compared with the prior art, the power distribution network fault handling method provided in this embodiment utilizes the cable monitoring device 1 to monitor the cables 81 in the external network and generate line fault information to send to the control system 3. At the same time, the load operation monitoring device 2 monitors the operation of multiple power distribution devices 6 and sends the load monitoring information to the control system 3. The control system 3 determines whether the fault is in the power distribution device 6 or the cable 81 in the external network based on the received information, and then issues corresponding control commands to restart the power distribution device 6 or repair the external network lines, thereby improving the timeliness of power distribution network maintenance and ensuring the stable operation of the power distribution network.

[0057] In some possible implementations, in the step where the control system 3 receives cable 81 fault information and load monitoring information, and determines whether the fault belongs to the power distribution equipment 6 or the external network line according to the preset program:

[0058] If the power distribution network is in a fault state of power distribution equipment 6, the control system 3 sends a restart command to the corresponding power distribution equipment 6;

[0059] If the distribution network is in a state of external network line fault, the control system 3 sends a maintenance command to the line stabilization and fixing unit 4 of the corresponding tower 8.

[0060] Specifically, after receiving line fault information and load monitoring information, the control system 3 can determine whether the fault lies with the power distribution equipment 6 or the external network line, based on its preset program. If the fault is with the power distribution equipment 6, the control system 3 will send a restart command to the faulty equipment 6 to automatically restart it and ensure its stable operation. If the control system 3 determines that there is a fault in the external network line, it will send a maintenance command to the line stabilization unit 4. The line stabilization unit 4 can effectively stabilize the end of the cable 81, achieving effective line maintenance. If the above operations cannot resolve the line fault, a maintenance command will be sent to the equipment terminal, and the corresponding maintenance personnel will perform manual maintenance at the fault point.

[0061] In some possible implementations, the steps of the load operation monitoring device 2 monitoring the operation of the power distribution equipment 6, generating load monitoring information and sending it to the control system 3, also include the load operation monitoring device 2 identifying the location information 11 and equipment code information 12 of the power distribution equipment 6, and sending the location information 11 and equipment code information 12 to the control system 3.

[0062] In this embodiment, when the load operation monitoring device 2 performs fault monitoring on multiple power distribution devices 6, it can identify the location information 11 and equipment coding information 12 of the power distribution devices 6. The above information can indicate the location information 11 or equipment coding information 12 of the corresponding power distribution device 6. The above information is sent to the control system 3 synchronously with the load monitoring information, so that the control system 3 can issue a restart control command to the corresponding power distribution device 6. At the same time, it also makes it easier for staff to understand which power distribution devices 6 are prone to failure or abnormality. In this way, the stable operation of the power distribution devices 6 can be ensured by enhancing manual inspection, ensuring the normal operation of the entire power distribution device 6 system, reducing the failure frequency of the power distribution devices 6, improving the maintenance efficiency of the equipment, and ensuring the effectiveness of monitoring.

[0063] In some possible implementations, the steps of the cable monitoring device 1 identifying the fault of the power distribution equipment 6, generating cable 81 fault information and sending it to the control system 3 may also include, when the control system 3 determines that the power distribution network is in an external network line fault state, using the drone 7 to conduct a review and inspection of the external network line of the power distribution network, collecting video information of the fault point of the external network line, and sending the video information to the control system 3 for review by the control system 3.

[0064] In this embodiment, if there is a fault in cable 81 in the external network of the power distribution network, video information can be collected using drone 7. Specifically, the control system 3 sends an inspection command to drone 7. After receiving the inspection command, drone 7 collects video information of the fault point in the external network and sends the video information to the control system 3 for judgment to ensure the accuracy of the fault point. Then, the control system 3 sends a maintenance command to the line stabilization and fixing unit 4 to complete the maintenance of cable 81.

[0065] Based on the same inventive concept, this application also provides a power distribution network fault handling device that uses a power distribution network fault handling method to handle faults. The power distribution network fault handling device includes several cable monitoring devices 1, several load operation monitoring devices 2, a control system 3, and several line stabilization and fixing units 4.

[0066] Several cable monitoring devices 1 are respectively installed on several poles 8 and are installed one-to-one with the poles 8. The cable monitoring devices 1 are installed close to the end of the cable 81 to identify the fault of the cable 81 and generate cable 81 fault information.

[0067] Several load operation monitoring devices 2 are respectively installed on several power distribution equipment 6 and are installed in one-to-one correspondence with power distribution equipment 6. The load operation monitoring devices 2 are used to identify faults in power distribution equipment 6 and generate load monitoring information.

[0068] The control system 3 is used to receive cable 81 fault information and load monitoring information, and determine whether the fault belongs to the power distribution equipment 6 or the external network line according to the preset program, and issue a restart command or maintenance command accordingly.

[0069] Several line stabilization and fixing units 4 are respectively installed on several poles 8 and are electrically connected to the control system 3 to receive automatic maintenance commands from the control system 3 and to perform maintenance on the external network lines.

[0070] When there is a fault in the power distribution equipment 6 in the power distribution network, the control system 3 sends a restart command to the corresponding power distribution equipment 6; when there is a fault in the external network line in the power distribution network, the control system 3 sends an automatic maintenance command to the corresponding line stabilization and fixing unit 4 so that the line stabilization and fixing unit 4 can perform maintenance on the external network line, or the control system 3 sends a manual maintenance command to the equipment terminal so that maintenance personnel can perform manual maintenance on the fault point.

[0071] Compared with the prior art, the power distribution network fault handling device provided in this embodiment monitors the external network lines and generates line fault information through the cable 81 monitoring device. At the same time, it monitors the operation of the power distribution equipment 6 and generates load monitoring information with the help of the load operation monitoring device 2. After receiving the cable 81 fault information and the load monitoring information, the control system 3 determines whether the fault belongs to the power distribution equipment 6 or the external network line according to the preset program, and then makes corresponding control commands to realize the restart of the power distribution equipment 6 or the maintenance of the external network line, which facilitates the improvement of the timeliness of power distribution network maintenance and ensures the stable operation of the power distribution network.

[0072] Among some possible implementations, see [link to relevant documentation]. Figure 2 The power distribution network fault handling device also includes several location information 11s that are set one-to-one with the power distribution equipment 6 and several equipment code information 12s that are set one-to-one with the power distribution equipment 6. The load operation monitoring device 2 is used to monitor the operation status of the power distribution equipment 6, identify the corresponding location information 11 and equipment code information 12, and send the location information 11 and equipment code information 12 to the control system 3.

[0073] In this embodiment, each power distribution device 6 corresponds to a location information 11 and a device code information 12. The load operation monitoring device 2 can not only monitor the operation of the power distribution device 6, but also synchronously identify the location information 11 and device code information 12 of the corresponding power distribution device 6, and transmit the above three pieces of information to the control system 3. This allows the control system 3 to accurately locate the power distribution device 6 and send an inflation control command to the faulty power distribution device 6, ensuring that the faulty power distribution device 6 can accurately receive the command and restart accordingly, thus ensuring the stable operation of subsequent equipment.

[0074] In some possible implementations, the aforementioned feature-stabilized and fixed-line unit 4 adopts, for example... Figures 2 to 7 The structure shown. See also Figures 2 to 7 The stabilizing and securing unit 4 includes a horizontal suspension rod 41, a wire clamping assembly 5, a fixed pulley 43, and a tension line 42. The end of the horizontal suspension rod 41 is connected to the tower 8 and extends outward along the direction of the cable 81. The wire clamping assembly 5 is installed on the cable 81 and is located near the end of the cable 81 adjacent to the tension insulator 82. The fixed pulley 43 is rotatably connected to the crossarm. The tension line 42 is connected to the wire clamping assembly 5 through a hook 46. The tension line 42 is wound around the outer periphery of the fixed pulley 43 and extends towards the horizontal suspension rod 41.

[0075] Among them, a lateral drive member 44 that can move along its extension direction is slidably connected to the horizontal suspension rod 41. The lateral drive member 44 can move towards the extended end of the horizontal suspension rod 41 to drive the clamping cable assembly 5 to approach the tower 8 and tension the cable 81.

[0076] In this embodiment, the horizontal suspension rod 41 is connected to the side of the tower 8 and extends along the extension direction of the cable 81, that is, it extends horizontally. The cable clamp assembly 5 is connected to the end of the cable 81 and is located near the tension insulator 82, that is, near the side of the tower 8, which can strengthen and stabilize the connection node of the end of the cable 81 and the tension insulator 82.

[0077] Specifically, the tension wire 42 is connected to the clamping wire assembly 5 via the hook connector 46. The clamping wire assembly 5, through the pulling action of the tension rope, moves the cable 81 towards the side closer to the tension insulator 82, that is, towards the side closer to the tower 8. The above operation can effectively reduce the tension between the end of the cable 81 and the tension insulator 82, avoid the line fault caused by the two separating, and ensure the reliable installation of the cable 81.

[0078] Furthermore, a fixed pulley 43 is provided on the tower 8 for the tension wire 42 to be wound around, which can improve the smoothness of the tension wire 42 pulling action, reduce the resistance during the tensioning process, increase the traction force of the tension wire 42 on the clamping wire assembly 5 and the end of the cable 81, reduce the separation between the end of the cable 81 and the tension insulator 82 due to its own weight, and ensure the stable operation of the entire line.

[0079] In this embodiment, the lateral drive 44 can drive the tension rope to move. The tension rope is wrapped around the outer circumference of the fixed pulley 43. During the movement of the tension rope, the fixed pulley 43 rotates synchronously, which can change the direction of the tension rope and avoid the space occupation caused by the excessively large tension rope moving beam.

[0080] In some possible implementations, the aforementioned lateral movement drive 44 adopts, for example... Figure 6 and Figure 7 The structure shown. See also Figure 6 and Figure 7 The lateral movement drive component 44 includes a motor 441, a lead screw 442, and a lead screw nut 443; the motor 441 is connected to the lower part of the horizontal suspension rod 41 and is located near the outer end of the horizontal suspension rod 41; the lead screw 442 is connected to the output end of the motor 441 and extends towards the tower 8; the lead screw nut 443 cooperates with the lead screw 442, and a hanging ring 444 connected to the tension line 42 is provided below the lead screw nut 443;

[0081] The horizontal suspension rod 41 is provided with a limiting ring 45 for limiting the tension line 42. The limiting ring 45 is located on the side of the nut 443 near the tower 8.

[0082] In this embodiment, the lateral drive 44 is used to drive the outer end of the tension rope to move horizontally, thereby driving the wire clamping assembly 5 and the end of the cable 81 clamped by the wire clamping assembly 5 to move horizontally, thereby fixing the end of the cable 81.

[0083] Based on this, a limiting ring 45 is provided on the horizontal suspension rod 41. The limiting ring 45 passes through the axial direction of the cable 81 to limit the tension rope, so as to prevent the tension rope from getting tangled with other components and affecting the tensioning action. In addition, it can also limit the tensioning direction of the tension rope.

[0084] In some possible implementations, the aforementioned feature clip wire assembly 5 adopts, for example... Figure 4 and Figure 5 The structure shown. See also Figure 4 and Figure 5 The cable clamping assembly 5 includes a hook block 51, a pull arm 52, and a clamping seat 53. The hook block 51 is hooked to one side of the cable 81. The pull arm 52 is rotatably connected to the lower part of the hook block 51 via a first pivot 521 and extends towards the side closer to the tower 8. The clamping seat 53 is rotatably connected to the middle part of the hook block 51 via a second pivot 531. The end of the clamping seat 53 near the tower 8 has a limiting collar 54 sleeved on the outer periphery of the pull arm 52 to limit the pull arm 52 from swinging downward away from the cable 81. The clamping seat 53 has a clamping surface that can abut against the bottom of the cable 81.

[0085] In this embodiment, the pull arm 52 is rotatably connected to the lower part of the hook block 51 via the first rotating shaft 521. Under the pulling action of the tension rope, it can rotate around the first rotating shaft 521, thereby driving the limiting ring 45 on the pressing seat 53, causing the pressing seat 53 to rotate around the second rotating shaft 531. The pressing surface presses the cable 81 from below, ensuring the stability of the relative position between the cable 81 and the hook block 51. The tensioning effect of the tension rope on the end of the cable 81 is achieved through the clamping cable assembly 5.

[0086] In some possible implementations, the aforementioned feature-attached block 51 adopts, for example... Figure 4 and Figure 5 The structure shown. See also Figure 4 and Figure 5 The upper part of the hook block 51 is provided with an extension 511 extending to the other side of the cable 81. The pressing seat 53 gradually tilts outward in an arc shape from bottom to top away from the second rotating shaft 531, and the cross-sectional area of ​​the pressing seat 53 gradually increases. A flexible pad 55 that abuts against the cable 81 is provided on the pressing surface.

[0087] In this embodiment, the flexible pad 55 can avoid scratching and damaging the surface of the cable 81. The pressing part adopts a structure that is larger at the top and smaller at the bottom, which can increase the contact area between the pressing surface and the cable 81, increase the extension length of the pressing surface in the axial direction of the cable 81, and improve the relative stability between the clamping cable assembly 5 and the cable 81.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
