Description

[0002] As an important part of the power system, the safe and stable operation of transmission lines is directly related to the reliability and stability of the entire power grid. However, lightning strikes, as one of the common natural disasters of transmission lines, pose a serious threat to the safe operation of the power grid.

[0003] Most traditional lightning strike fault detection methods rely on manual inspections and post-event analyses, suffering from problems such as low detection efficiency and inaccurate positioning. Especially in some mountainous lightning strike areas, most of the transmission towers are located on the mountaintops, making the inspection paths very difficult. Moreover, lightning strikes can damage fittings such as conductors, posing potential hazards to the operation of transmission lines. Therefore, the investigation of traditional lightning strike faults can only rely on manual inspections, which not only takes a long time and has low efficiency, but also is very difficult.

[0004] Therefore, it is particularly important to develop a device that can monitor in real time and accurately locate lightning strike faults. It can quickly send the lightning strike location range to transmission personnel after a lightning strike fault occurs, quickly eliminate the hidden dangers of lightning strikes on transmission lines, and can carry out special renovations on transmission lines under special operating conditions based on the collected lightning strike meteorological data, which is of great significance for reducing the inspection pressure of transmission operation and maintenance personnel, improving the line operation and maintenance level, and enhancing the reliability of the power grid.

[0016] The present invention is not limited by the following embodiments, and the specific implementation manners can be determined according to the technical solutions of the present invention and the actual situation.

For example, the position relationships such as front, rear, upper, lower, left, and right are determined according to the layout direction of the attached drawings of the specification.

[0018] The present invention will be further described below in conjunction with the embodiments and the drawings: As shown in the attached Figure 1As shown in the figure, the device for locating transmission line lightning strike faults based on the infrared principle includes an installation cylinder 1 and a power module. Inside the installation cylinder 1, a monitoring module 2, a positioning module, and a controller module 3 are respectively installed. On the outside of the installation cylinder 1, a communication module 4 is fixedly installed. The power module is electrically connected to the monitoring module 2, the positioning module, the communication module 4, and the controller module 3 together. The monitoring module 2, the positioning module, the communication module 4, and the controller module 3 are all publicly known and commonly used. The structure of the present invention is reasonable and compact, and it is convenient to use. Through the coordinated use of the monitoring module 2, the positioning module, and the controller module 3, the purpose of more accurately determining the lightning strike position of the transmission line 11 is achieved. It has the characteristics of safety and reliability and short lightning strike fault troubleshooting time, which facilitates operation, improves work efficiency, and reduces the patrol intensity of on-site operation and maintenance personnel.

[0019] The monitoring module 2 is used to transmit lightning strike position and time information to the monitoring background, and includes an infrared detection sensor and a sound source collection sensor.

[0020] The positioning module is used to obtain the coordinate information of the lightning strike point and send it to the communication module 4.

[0021] The communication module 4 is used to send the collected lightning strike positioning information to the monitoring background through Beidou.

[0022] The controller module 3 is used for power management and processing information such as infrared, sound source, and positioning, and encrypts and transmits the above information to the background through this module.

[0023] According to actual needs, the above device for locating transmission line lightning strike faults based on the infrared principle can be further optimized or / and improved: As shown in the appendix Figure 1 As shown in the figure, the power module is a solar panel, and the solar panel is fixedly installed on the installation cylinder 1; or / and, the power module is a photovoltaic power generation module 5, and the photovoltaic power generation module 5 is installed inside the installation cylinder 1; or / and, the power module is a micro wind power generation module 6, and the micro wind power generation module 6 is fixedly installed on the installation cylinder 1; or / and, the power module is a battery module 7, and the battery module 7 is installed inside the installation cylinder 1. The power module includes a solar panel, a photovoltaic power generation module 5, a micro wind power generation module 6, and a battery module 7; and is used to provide electrical energy for the monitoring module 2.

[0024] According to needs, the monitoring module 2 includes an infrared module and a sound source module.

[0025] As shown in the appendix Figure 1 As shown in the figure, an installation frame is fixedly installed on the outside of the installation cylinder 1. The installation frame is used to fix the device on the transmission tower or near the tower.

[0026] As shown in the appendix Figure 1As shown in the figure, the mounting bracket includes a mounting rod 8. On the upper right side of the mounting rod 8, a clamping plate 9 is fixedly connected. The upper part of the mounting rod 8 and the clamping plate 9 are respectively fixedly installed with the mounting cylinder 1. On the upper left and middle left sides of the mounting rod 8, mounting columns 10 are respectively fixedly connected. In this way, it is convenient to fixedly install the device on the transmission tower or near the tower through the mounting columns 10.

[0027] As shown in the appendix Figure 2 As shown in the figure, three such devices (the device for positioning transmission line lightning strikes based on the infrared principle of the present invention) are arranged at three locations A, B, and C near the transmission line 11, and the monitoring ranges (represented by circles) at the three locations A, B, and C are respectively marked.

[0028] Furthermore, according to the data of past historical transmission line lightning strikes, the device is installed on the line segment with a relatively high frequency of lightning strikes on the transmission line 11 or at a relatively high position nearby. The solar panel or the micro wind power generation module 6 (wind turbine) or the battery module 7 (energy storage battery) provides power for the monitoring module 2 (including the infrared module and the sound source module), the positioning module, the communication module 4, and the controller module 3 (controller). The solar panel and the wind turbine are used to convert solar energy and wind energy into electrical energy and store it in the energy storage battery. The infrared module is used to monitor the infrared data near the transmission line 11 in real time.

[0029] As shown in the appendix Figure 3 As shown in the figure, the controller module 3 (controller) is used to receive the data collected by the infrared and sound source modules, and perform data processing and analysis to determine whether there is a lightning strike fault, and calculate through the infrared data and the sound source data to improve the positioning accuracy. The communication module 4 is used to transmit the lightning strike fault location information to the monitoring background and the transmission line maintenance personnel in real time through the network, and compare the uploaded background GPS information with the geographical location information of the transmission line 11 in the PMS to confirm the pole number interval of the corresponding transmission line 11 at this location, and send it to the transmission line maintenance personnel. The monitoring device can improve the positioning accuracy of the lightning strike fault point through measures such as multi-point layout.

[0030] During the working period, the infrared and sound source information near the transmission line 11 is collected at all times to ensure that once a lightning strike fault occurs, the controller can process and encrypt the data and send it to the monitoring background for the first time, and perform collaborative positioning through multiple devices (the device for positioning transmission line lightning strikes based on the infrared principle of the present invention) through the monitoring background, and send the final fault location to the transmission line maintenance personnel.

[0031] The controller and the communication module 4 upload the location information to the monitoring background for recording, and combine the feedback from the transmission line maintenance personnel to form lightning strike meteorological data, providing real and accurate lightning strike meteorological data for the subsequent renovation and new construction of the transmission line 11.

[0032] The working process of the present invention is as shown in the appendixFigure 1 , 2 As shown in Figure 3, first, components such as solar panels, micro wind power generation modules 6 (wind turbines), battery modules 7 (energy storage batteries), monitoring modules 2, SIM card Internet of Things modules, and communication modules 4 (communication antennas) are assembled to ensure reliable and stable connections between components. Then, the assembled device is installed on the mounting bracket and debugged to ensure that the device can work properly. After the device is started, the controller will automatically detect the output power of the solar panels and wind turbines and intelligently control the charging and discharging of the energy storage battery according to the power level of the energy storage battery. In the case of sufficient sunlight or strong wind, the controller will preferentially use the electric energy generated by the solar panels or wind turbines for power supply; in the case of no sunlight or no wind, the controller will switch to the energy storage battery power supply mode to ensure that the device can continue to work. Once a lightning strike fault occurs, the infrared module will continuously monitor the infrared distribution near the transmission line 11 and send the collected infrared data to the controller. The controller will process and analyze the infrared data to determine whether there is a lightning strike fault. When a lightning strike fault is detected, the sound source module collects the time information of the thunder after the lightning strike, and through the controller, it comprehensively calculates with the lightning strike time monitored by the infrared module to assist in accurately positioning the lightning strike location. After the calculation, the controller immediately triggers the alarm mechanism and transmits the lightning strike fault location and frequency information to the transmission and operation and maintenance personnel in real time through the SIM card Internet of Things module. To improve the positioning accuracy of the lightning strike fault point, the present invention supports multi-point layout, that is, multiple such devices are installed at different positions on the transmission line 11. Through data fusion of multiple devices, the lightning strike location is calculated more accurately. The specific implementation method is as follows: Each device sends the collected temperature data to the monitoring background. Through the monitoring background, the data of multiple devices are comprehensively analyzed, and through algorithms, a more accurate location of the lightning strike fault point is calculated. By comparing this location with the geographical location in the PMS system, the pole number section of the transmission line 11 where the lightning strike fault may occur is fed back to the transmission and operation and maintenance personnel in real time. The operation and maintenance personnel can remotely monitor the working status of the device and view the lightning strike fault information through terminal devices such as mobile phones and computers, so as to take timely measures for disposal. At the same time, the device also has functions such as remote upgrade and fault self-diagnosis, which is convenient for the operation and maintenance personnel to carry out remote maintenance and management.

[0033] The above technical features constitute an embodiment of the present invention, which has strong adaptability and implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
