Description

Technical Field

[0001] This invention relates to the field of power distribution fault location, specifically a rapid fault location and debugging optimization system for high and low voltage power distribution. Background Technology

[0002] Distribution lines are lines that transmit electricity from step-down substations to distribution transformers or end-user equipment, while transmission lines are power lines that transmit electricity from the generating end through a transmission network over long distances after voltage enhancement. In actual power systems, both high-voltage transmission lines and low-voltage distribution lines play a crucial role in power transmission, and their operating status directly affects the stability and security of the power supply.

[0003] During operation, power transmission and distribution lines are easily affected by wind, sand, dust, rain, oil, and other pollutants due to long-term exposure to the outdoor environment. They may also experience aging, insulation damage, and poor contact, leading to faults such as short circuits, grounding, or open circuits. Therefore, after a fault occurs, fault location devices are typically used to inspect the line to quickly pinpoint the fault location and carry out repairs.

[0004] In the prior art, for example, Chinese invention application number 202122501660.6 discloses an early fault location device for power distribution lines. This device is fixed to the cable by a retaining ring and a fastening structure to realize the detection of line status and fault early warning. However, such devices mostly adopt a fixed installation method, which can only monitor local locations. It requires the cooperation of multiple devices to realize the judgment of the fault section, resulting in a large location range, low accuracy, and is not conducive to rapid repair.

[0005] To address the aforementioned issues, Chinese invention publication CN218886051U also discloses a fault location device that can move along a cable. By using a walking mechanism to drive the detection components to move along the line, it achieves dynamic scanning and location of faulty sections, thereby improving the location efficiency to a certain extent.

[0006] However, in practical applications, the above solutions often suffer from dust, moisture, oil, and other impurities due to the long-term exposure of the lines to the outdoor environment. When the detection device moves along the line, the detector directly detects the contaminated cables, which is easily affected by external deposits, thus affecting the stability and accuracy of the detection signal and potentially leading to misjudgments or missed detections. In addition, although the existing devices can be propelled by wind during movement, the resulting airflow is mostly divergent and fails to effectively direct the airflow to the cable surface, making it difficult to effectively remove deposits and thus providing a good detection environment for subsequent testing. Therefore, we propose a rapid fault location and debugging optimization system for high and low voltage power distribution. Summary of the Invention

[0007] The purpose of this invention is to provide a rapid fault location device for high and low voltage power distribution, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, a high and low voltage power distribution fault rapid location device includes a housing, a top plate disposed above the housing, a detection component disposed on the housing, and a height adjustment component and a walking drive component disposed between the housing and the top plate. A fan is provided on the side of the housing near the direction of travel of the device. The air outlet of the fan is connected to an air guide hood. The fan is fixed to the housing by a mounting bracket. The mounting bracket is provided with a cleaning brush groove for the power transmission line to pass through. The cleaning brush groove is provided with bristles. The cleaning brush groove and the detection component are arranged sequentially along the direction of travel of the device.

[0009] Furthermore: a solar panel is provided on the top plate, a battery electrically connected to the solar panel is provided inside the housing, a main control module is also provided inside the housing, the main control module is electrically connected to the detection components and the fan, and integrates a signal transmission module and a positioning module, and an audible and visual alarm is provided at the bottom of the housing.

[0010] Furthermore: the height adjustment assembly includes an adjustment screw, a lifting plate, and a guide connecting rod. The adjustment screw is rotatably disposed under the housing and rotatably connected to the lifting plate. One end of the guide connecting rod is fixedly connected to the lifting plate, and the other end passes through the housing and is fixedly connected to the top plate.

[0011] Furthermore: the walking drive assembly includes a drive wheel, a driven wheel, a follower pressure wheel, and a wheel system connecting frame. The drive wheel is connected to the drive motor and is connected to the driven wheel via a synchronous transmission belt. The follower pressure wheel is mounted on the wheel system connecting frame and rotates under the top plate.

[0012] Furthermore, the outer edges of the driving wheel, driven wheel, and follower clamping wheel are all provided with meshing toothed rings that mesh with each other.

[0013] Furthermore, the inner sides of the driving wheel, driven wheel, and follower pressing wheel are all provided with a trapezoidal inclined structure to adapt to the power transmission line.

[0014] Furthermore: the air outlet of the air guide shroud faces the power transmission line and is inclined, and the mounting bracket is composed of a fixed plate and a detachable plate.

[0015] A commissioning and optimization system for rapid fault location in high and low voltage power distribution is disclosed. The system is bidirectionally connected to a main control module and includes a data acquisition unit, a fault calibration unit, a travel optimization unit, a cleaning adaptation unit, and a remote commissioning unit. The data acquisition unit collects detection data from detection components, operating parameters of the travel drive components, operating parameters of the wind turbine, and environmental parameters of the transmission line, and transmits them to the main control module. The fault calibration unit pre-stores a standard detection feature library for different fault types in the transmission line and compares the detection data acquired by the data acquisition unit with the standard detection feature library to adjust the detection thresholds of the detection components. The system includes dynamic calibration; the travel optimization unit automatically adjusts the output power of the drive motor and the clamping distance of the height adjustment component based on the wheel speed, meshing transmission state, and line clamping tightness of the travel drive component, thereby optimizing the stability of the device's travel; the cleaning adaptation unit dynamically adjusts the fan's output power based on dust concentration and humidity data in the environmental parameters, adapting to the line cleaning needs in different environments; and the remote debugging unit establishes communication with the remote monitoring terminal through the signal transmission module of the main control module, supporting remote modification and debugging of the operating parameters of the detection component, travel drive component, and fan, and receiving operational status feedback data of the device.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting a fan, a guide hood, and a cleaning brush groove structure on the front side of the housing and arranging them sequentially with the detection components along the direction of travel, the device first cleans the line by contact with the brush bristles as it moves along the power transmission line, and then guides the airflow to blow the line surface in a directional manner by the guide hood. This effectively pre-treats the line before detection, avoids interference from dust, water vapor, and other adhering substances on the detection results, and significantly improves the accuracy and stability of the detection data. 2. The height adjustment component enables adaptive clamping of transmission lines of different specifications. Combined with the multi-point support walking drive structure consisting of a drive wheel, a driven wheel, and a follow-up clamping wheel, the device is more stable and reliable during travel, reducing the risk of slippage.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 The figure shows a preferred embodiment of the present invention, a high and low voltage power distribution fault rapid location device, including a housing 1, a top plate 3 disposed above the housing 1, a detection component 2 disposed on the housing 1, and a height adjustment component 4 and a walking drive component 5 disposed between the housing 1 and the top plate 3. A fan 6 is provided on the side of the housing 1 near the direction of travel of the device. The air outlet of the fan 6 is connected to a guide shroud 7. The fan 6 is fixed to the housing 1 by a mounting bracket 8. The mounting bracket 8 is provided with a cleaning brush groove 9 for the power transmission line to pass through. The cleaning brush groove 9 is provided with bristles, and the cleaning brush groove 9 and the detection component 2 are arranged sequentially along the direction of travel of the device.

[0021] Specifically, a solar panel 10 is installed on the top plate 3, and a battery 11 electrically connected to the solar panel 10 is installed inside the housing 1. A main control module 12 is also installed inside the housing 1. The main control module 12 is electrically connected to the detection component 2 and the fan 6, and integrates a signal transmission module and a positioning module. An audible and visual alarm 13 is installed at the bottom of the housing 1. By installing a solar panel 10 on the top plate 3 and an electrically connected battery 11 inside the housing 1, continuous power supply to the device can be achieved, reducing dependence on external power. By installing the main control module 12 inside the housing 1 and electrically connecting it to the detection component 2 and the fan 6, centralized processing of detection data and operation control of the fan 6 can be achieved. At the same time, the main control module 12 integrates a signal transmission module and a positioning module, which can remotely transmit detection results and achieve positioning marking. In addition, by installing an audible and visual alarm 13 at the bottom of the housing 1, on-site alarm prompts can be given when an abnormality is detected, thereby improving the intelligence and practicality of the device.

[0022] The height adjustment assembly 4 includes an adjusting screw 14, a lifting plate 15, and a guide connecting rod 16. The adjusting screw 14 is rotatably mounted under the housing 1 and rotatably connected to the lifting plate 15. One end of the guide connecting rod 16 is fixedly connected to the lifting plate 15, and the other end passes through the housing 1 and is fixedly connected to the top plate 3. The adjusting screw 14 is rotatably mounted at the lower part of the housing 1 and rotatably connected to the lifting plate 15. The guide connecting rod 16 connects the lifting plate 15 and the top plate 3. When the adjusting screw 14 is rotated, the lifting plate 15 can be moved up and down, and the distance between the top plate 3 and the housing 1 can be adjusted synchronously through the guide connecting rod 16, thereby achieving stable clamping of transmission lines of different diameters and improving the adaptability and stability of the device.

[0023] In addition, the walking drive assembly 5 includes a drive wheel 17, a driven wheel 19, a follower clamping wheel 20, and a wheel system connecting frame 22. The drive wheel 17 is connected to the drive motor and is connected to the driven wheel 19 via a synchronous transmission belt 18. The follower clamping wheel 20 is mounted and rotates under the top plate 3 via the wheel system connecting frame 22. The drive wheel 17 rotates under the action of the drive motor and drives the driven wheel 19 to rotate synchronously via the synchronous transmission belt 18. At the same time, the follower clamping wheel 20 is rotatably mounted under the top plate 3 via the wheel system connecting frame 22. The three components together clamp the power transmission line and achieve multi-point support, thereby making the device walk more smoothly along the line and avoiding slippage or deviation.

[0024] Specifically, the outer edges of the driving wheel 17, driven wheel 19 and follower clamping wheel 20 are all provided with meshing tooth rings 21 that mesh with each other; so that each wheel can form a meshing transmission relationship when it contacts the power transmission line, thereby enhancing the coordinated rotation effect between the wheels, improving the driving synchronization, and further improving the stability and anti-slip performance of the device when it moves along the line.

[0025] Meanwhile, the inner sides of the driving wheel 17, driven wheel 19 and follower clamping wheel 20 are all provided with trapezoidal inclined structures to adapt to power transmission lines; during the clamping process, they can automatically center and increase the contact area, thereby improving clamping stability and preventing deviation or detachment during operation.

[0026] Understandably, the air outlet of the air guide shroud 7 faces the power transmission line and is set at an angle, so that the airflow generated by the fan 6 acts on the surface of the power transmission line at a certain angle, achieving directional blowing of the attached dust; the mounting bracket 8 consists of a fixed plate and a detachable plate. This allows the power transmission line to be placed into the cleaning brush groove 9 after opening, and then the surface of the line can be cleaned by contact with the brush bristles, thus forming a combined cleaning method of brush cleaning and airflow blowing, providing a more stable testing environment for the testing component 2.

[0027] In this embodiment, during use, the power transmission line is first installed into the cleaning brush groove 9 through the detachable plate structure on the mounting bracket 8, so that the power transmission line passes through the front end area of ​​the housing 1; then, by rotating the adjusting screw 14, the lifting plate 15 is driven to move up and down under the guidance of the guide connecting rod 16, thereby adjusting the distance between the top plate 3 and the housing 1, so that the driving wheel 17, the driven wheel 19 and the follow-up pressing wheel 20 form a stable clamp on the power transmission line.

[0028] After installation, the drive motor drives the active wheel 17 to rotate, and drives the driven wheel 19 to rotate synchronously through the synchronous transmission belt 18. Under the pressure of the follower clamping wheel 20, the device moves stably along the power transmission line. During the movement, when the power transmission line passes through the cleaning brush groove 9, the brush bristles clean its surface by contact. The fan 6 set on the front side of the housing 1 starts, and the airflow generated is guided by the air guide 7 and forms a directional airflow along the surface of the power transmission line. This airflow blows away the deposits composed of dust, water vapor or slight pollutants that are attached to the surface of the power transmission line and whose surface structure has been damaged by the brush bristles, thereby improving the surface condition of the power transmission line.

[0029] After cleaning, the transmission line enters the detection component 2 area. Detection component 2 can employ existing technologies such as electric field strength detection sensors, partial discharge detection sensors, infrared temperature sensors, or current and voltage anomaly detection modules. Its working principle is to determine whether the transmission line has insulation aging, poor contact, or local faults by sensing changes in the electric field, partial discharge signals, temperature anomalies, or fluctuations in electrical parameters generated during the operation of the transmission line. Since the surface of the transmission line has been pre-treated by the fan 6 and cleaning brush trough 9, interference from dirt and water film on the detection signal can be effectively reduced, thereby improving detection accuracy and stability.

[0030] After the detection data is transmitted to the main control module 12 for analysis and processing, when an abnormality is detected, on the one hand, the sound and light alarm 13 provides on-site prompts, and on the other hand, the fault information and the location information obtained by the positioning module are sent to the remote terminal through the signal transmission module, so as to realize the rapid location of the power transmission line fault.

[0031] Meanwhile, the solar panel 10 continuously charges the battery 11 during use, providing stable power support for the device, making it suitable for long-distance, high-altitude or field transmission line inspection operations.

[0032] A commissioning and optimization system for rapid fault location in high and low voltage power distribution is disclosed. The system is bidirectionally connected to a main control module 12. The system includes a data acquisition unit, a fault calibration unit, a travel optimization unit, a cleaning adaptation unit, and a remote commissioning unit. The data acquisition unit collects detection data from the detection component 2, operating parameters of the travel drive component 5, operating parameters of the fan 6, and environmental parameters of the transmission line, and transmits them to the main control module 12. The fault calibration unit pre-stores a standard detection feature library for different fault types in the transmission line, compares and matches the detection data acquired by the data acquisition unit with the standard detection feature library, and adjusts the detection threshold of the detection component 2 accordingly. The system includes dynamic calibration; the travel optimization unit automatically adjusts the output power of the drive motor and the clamping distance of the height adjustment component 4 based on the wheel speed, meshing transmission state, and line clamping tightness of the travel drive component 5, thereby optimizing the stability of the device's travel; the cleaning adaptation unit dynamically adjusts the air output power of the fan 6 based on dust concentration and humidity data in the environmental parameters, adapting to the line cleaning needs in different environments; and the remote debugging unit establishes communication with the remote monitoring terminal through the signal transmission module of the main control module 12, supporting remote modification and debugging of the operating parameters of the detection component 2, travel drive component 5, and fan 6, and receiving feedback data on the device's operating status.
