These drawings and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Invention
[0065] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the drawings.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.
[0067] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.
[0068] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards, and corresponding operation entrances are provided for the user to choose to authorize or refuse.
[0069] In power tests, the loop resistance test of GIS equipment is an important means to judge the operating state and electrical performance of the equipment. The loop resistance test is used to verify the connection quality of the circuit. A complete electrical connection means that the connections between all components and conductors are firm and defect-free.
[0070] By measuring the loop resistance, the quality of the circuit connection can be judged, and any problems that may lead to an incomplete connection can be detected. For example, a too high loop resistance may indicate poor contact, corrosion or other problems in the GIS equipment, which in turn affects the normal operation of the GIS equipment. The size of the loop resistance directly affects the current transmission efficiency. By measuring the loop resistance, the electrical performance of the GIS equipment during actual operation can also be detected.
[0071] To perform a loop resistance test on GIS equipment, traditional methods usually use an aerial work platform such as a lift platform or a gondola to lift the tester to the position of the GIS equipment to be tested. After that, the test points for the loop resistance test are identified on the GIS equipment, and the tester manually connects the test clips to the test points of the GIS equipment. After ensuring that the test clips are firmly connected to the GIS equipment, start the loop resistance test equipment to perform the test and record the test results.
[0072] However, manually connecting the test clips at high altitude has certain safety hazards, especially in adverse weather conditions. When there are multiple test points to be checked, the entire process of manually connecting the test clips and performing the loop resistance test can be very time-consuming, resulting in low test efficiency. At the same time, manually connecting the test clips may cause problems such as poor contact and insufficiently firm connection due to uneven force, thus affecting the accuracy and reliability of the test results.
[0073] Therefore, the existing loop resistance test methods have poor operability and certain insecurity.
[0074] To address the above technical problems, the inventor thought of using a telescopic rod to replace the lifting function of the aerial work platform, and designing the end of the telescopic rod as an electrical contact clip to replace the manual operation of the tester. To further improve the test safety, the inventor also connected the other end of the telescopic rod to the ground control terminal, and the tester can control the movement of the telescopic rod and the grasping of the electrical contact clip through the ground control terminal. This avoids the direct contact between the tester and the electrical contact clip and the GIS equipment, improving the test safety while ensuring the operability of the loop resistance test.
[0075] The following uses specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the drawings.
[0076] The embodiment of the present application provides a loop resistance test method for GIS equipment. Figure 1The flow schematic diagram of the loop resistance testing method for GIS devices provided by the embodiments of this application is as follows: Figure 1 As shown, the loop resistance testing method for GIS devices includes:
[0077] S101. Determine the GIS device to be detected and its location coordinates.
[0078] Explanatorily, each GIS device usually has a unique identifier, such as a serial number or an asset number. Through the identifier, each GIS device can be accurately identified in the device management system.
[0079] The location coordinates can be an important data point in the device management system, helping to establish a comprehensive GIS device database. This is because GIS devices are usually distributed in a wide geographical area, especially in large power grids. Precise geographical coordinates can help testers quickly find specific GIS devices.
[0080] S102. Move one end of the target telescopic rod to the location coordinates of the GIS device, and connect the other end to the target ground control terminal.
[0081] It can be understood that the target telescopic rod consists of multiple telescopic structures and can freely adjust its length according to the location coordinates of the GIS device. The target telescopic rod can adopt high-strength lightweight materials, such as carbon fiber or aluminum alloy. High-strength lightweight materials provide better stability and accuracy. Especially in cases where precise positioning or operation is required, the stability of high-strength lightweight materials helps to reduce the sway of the target telescopic rod during movement and improve the accuracy of operation.
[0082] One end of the target telescopic rod close to the GIS device is designed as two electrical contact clips with automatic clamping and releasing functions. It should be noted that the surfaces of the two electrical contact clips can be coated with high-conductivity materials to reduce contact resistance and improve measurement accuracy.
[0083] The other end of the target telescopic rod is connected to the target ground control terminal, which is a device for monitoring, controlling, and recording data. With this connection method, testers can adjust the operation of the target telescopic rod in real time through the target ground control terminal, or it can be automatically adjusted by the target ground control terminal. Among them, the target telescopic rod is equipped with an angle adjustment component to support flexible positioning in multiple directions, ensuring that one end of the target telescopic rod can reach the location coordinates of the GIS device.
[0084] S103. Determine two target test points of the GIS device, and control the two electrical contact clips to expand, contract, and rotate to grab the two target test points.
[0085] Since the basic principle of loop resistance testing is to calculate the resistance by measuring the voltage drop of the current in the electrical loop, two target test points need to be selected in the GIS device to measure the voltage drop. However, directly selecting two target test points on the GIS device may face some practical operation challenges, such as the complexity of the GIS device and safety considerations. Therefore, the display device of the target ground control terminal can be used to assist in the selection.
[0086] Specifically, obtain the component list of the GIS device and determine the size of each component in the component list. Shrink the size of each component according to the preset shrinkage ratio. After that, determine the component layout of the GIS device and the connection method between components. Based on the shrunk component size, component layout, and connection method between components, generate the structural model of the GIS device and display it on the display device of the target ground control terminal.
[0087] Explanatorily, the actual GIS device may be very large, while the screen size of the display device of the target ground control terminal is limited and cannot directly display the GIS device with actual size. By shrinking the component size, the entire GIS device can be adapted to the screen for easy viewing and operation.
[0088] After displaying the structural model of the GIS device on the display device of the target ground control terminal, determine two preset test points in the structural model. Among them, the preset test points are usually selected according to the test requirements and device structure, representing the ideal positions where loop resistance testing needs to be carried out on the actual GIS device. Based on the preset laser ranging method and preset visual recognition method, determine two target test points corresponding to the two preset test points on the GIS device.
[0089] Laser ranging is a method for accurately measuring distances, which uses a laser beam to measure the distance from one point to another point. Through this method, the distance from the target ground control terminal to each point on the GIS device can be accurately measured. Visual recognition uses a camera and image processing algorithms to identify and locate objects. Through visual recognition, specific components and features on the GIS device can be obtained to assist in locating the target test points.
[0090] Combining the preset laser ranging method and preset visual recognition method, the positions of the actual test points on the GIS device can be automatically calculated, that is, determine two target test points corresponding to the two preset test points on the GIS device.
[0091] Furthermore, through the target ground control terminal, control the two electrical contact clips on the target telescopic rod to grab the two target test points, where each electrical contact clip grabs one target test point. The electrical contact clips also have telescopic and rotating functions, and can accurately locate and grab the target test points to ensure good electrical connection.
[0092] It should be noted that in this embodiment, an autonomous learning technology is adopted to achieve the grasping of target test points. By continuously optimizing the operation path and grasping parameters through measuring historical data, the working efficiency and stability of the electrical contact clip are improved.
[0093] Specifically, obtain the historical operation paths and historical grasping parameters of two electrical contact clips. Among them, the historical operation path includes the historical telescopic path and the historical rotation path. Determine the grasping success rate corresponding to the historical operation path and the historical grasping parameters, learn the grasping success rate based on a preset learning strategy, and calculate the target operation path and the target grasping parameters required for grasping two target test points. Based on the target operation path and the target grasping parameters, control the two electrical contact clips to perform telescoping and rotation to grasp two target test points.
[0094] Among them, a pressure sensor is integrated in the electrical contact clip, which can monitor the target grasping parameters in real time to ensure good contact between the electrical contact clip and the target test point. In addition, an acceleration sensor, a pressure sensor and a temperature sensor are also integrated in the electrical contact clip to monitor the operating state of the electrical contact clip in real time to prevent abnormalities.
[0095] It should be understood that since multiple sensors are integrated in the electrical contact clip, these sensors rely on power to work. A high-capacity rechargeable lithium battery can be used to supply power to the electrical contact clip. At the same time, the electrical contact clip supports fast charging and modular battery replacement to ensure long-term continuous operation.
[0096] S104. Form an electrical loop between two target test points, perform a loop resistance test on the electrical loop, and put the GIS device that passes the loop resistance test into use in the power system.
[0097] It should be noted that loop testers are installed on both of the two electrical contact clips. When the two electrical contact clips respectively grasp two target test points on the GIS device, the two target test points are connected by the wires of the loop tester to form a complete electrical loop. This electrical loop allows current to flow through, so that various electrical measurements can be carried out.
[0098] Specifically, apply a preset known current to the electrical loop, and measure the loop voltage drop of the electrical loop based on the voltage sensor in the loop tester. Feed back the loop voltage drop to the target ground control terminal. Among them, the loop tester and the target ground control terminal are wirelessly connected through 5G or WiFi to achieve real-time data transmission and control signal feedback.
[0099] It should be noted that the loop tester is also equipped with built-in data encryption and anti-interference components to ensure the integrity and security of the measurement data during wireless communication.
[0100] Next, based on the preset known current and the loop voltage drop feedback, the loop resistance test of the electrical loop is carried out at the target ground terminal. Explanatorily, based on the preset known current and the loop voltage drop, the loop resistance value of the electrical loop is calculated through the target ground control terminal, where the loop resistance value = loop voltage drop / preset known current.
[0101] If the loop resistance value is within the preset safety range, it indicates that the electrical loop passes the loop resistance test; if the loop resistance value is not within the preset safety range, it indicates that the electrical loop fails the loop resistance test.
[0102] Furthermore, the GIS equipment that passes the loop resistance test is put into use in the power system. For the GIS equipment that fails the loop resistance test, troubleshoot the electrical loop and / or the GIS equipment to identify the cause of the failure of the loop resistance test, and based on the cause of the failure, maintain the electrical loop and / or the GIS equipment, and re-perform the loop resistance test on the maintained electrical loop.
[0103] After the completion of this loop resistance test, control the electrical contact clip to release the fixture, and retract the target telescopic rod, automatically reset to the initial state, and prepare for the next loop resistance test.
[0104] The loop resistance test method for GIS devices provided in this application determines the GIS device to be detected and the position coordinates of the GIS device. One end of the target telescopic rod is moved to the position coordinates of the GIS device, and the other end is connected to the target ground control terminal. One end of the target telescopic rod close to the GIS device is designed as two electrical contact clips. Then, the structural model of the GIS device is displayed on the display device of the target ground control terminal, and two preset test points are determined in the structural model. Based on the preset laser ranging method and the preset visual recognition method, two target test points corresponding to the two preset test points are determined on the GIS device. Next, based on the historical operation path and historical grasping parameters of the two electrical contact clips and the corresponding grasping success rate, the grasping success rate is learned based on the preset learning strategy, and the target operation path and target grasping parameters required to grasp the two target test points are calculated. Based on the target operation path and target grasping parameters, the two electrical contact clips are controlled to expand, contract, and rotate to grasp the two target test points, with each electrical contact clip grasping one target test point. Further, an electrical loop is formed between the two target test points. By applying a preset known current to the electrical loop, the loop voltage drop of the electrical loop is measured. Based on the preset known current and the loop voltage drop, the loop resistance test of the electrical loop is performed. The GIS device that passes the loop resistance test is put into use in the power system, and the GIS device that fails the loop resistance test is maintained. Using the target telescopic rod can not only avoid high-altitude operations by testers and reduce insecurity, but also support test requirements at different heights and angles and is applicable to various complex on-site environments. When there are multiple target test points to be inspected, the target test points can be quickly grasped by expanding, contracting, and rotating the electrical contact clips, greatly improving the test efficiency. In addition, the electrical contact clips can provide a stable grasping force, combined with the target ground control terminal, to improve the reliability and accuracy of the test. Therefore, this application can improve the operability and safety of the loop resistance test.
