Description
Technical Field
[0001] The invention relates to the technical field of distance measurement for high voltage tests of power transmission lines, and in particular to an intelligent control method and a test platform for gap discharge characteristics based on a hanging basket method assisted by laser ranging technology. Background Art
[0002] At present, when conducting high-voltage tests simulating the helicopter hanging basket method, the manned hanging basket and the simulated wires on both sides of the simulated line are connected to the gantry crane through a hanging rope. During the high-voltage test, in order to resist the shaking caused by wind and avoid the influence of these shaking on the phase distance and the combined gap distance, which will lead to errors in the test results, the simulated wires and the hanging basket on both sides must be effectively fixed. Considering that it is very important to ensure the accuracy of the high-voltage test, manpower is required to pull at the four corners during the test to adjust and fix the simulated wires and the manned hanging basket on both sides of the test. This process is not only cumbersome, but also time-consuming and labor-intensive. If the operator pulls and fixes the simulated wires on both sides by pulling the traction rope, if the operation is improper due to physiological or psychological factors, it may affect the accuracy of the test. Therefore, it is necessary to design an automatic wire pulling device that can fix and move the simulated wires and the hanging basket on both sides during the test, and promptly detect and correct the position deviation caused by wind.
[0003] Previous safety measures, including strengthening the safety awareness of test personnel, improving fixed equipment and adding on-site monitoring personnel, are facing new challenges brought about by the expansion of the test scale and the increase in the height of experimental equipment: 1. Test personnel may reduce their safety awareness or make operational errors due to fatigue during long-term operation. 2. Due to the height and field of view of the tower, as well as external environmental factors, it is difficult to fully grasp the test status through naked eye monitoring, especially the execution of the position adjustment steps. 3. Traditional equipment fixing methods are backward. Usually, after the test equipment is blown and offset by the wind, the naked eye cannot measure the distance between the equipment, which increases the possibility of errors. 4. Existing methods fail to fully consider the operational abnormalities that may be caused by physical factors such as exhaustion of test personnel. Summary of the invention

This system reduces the physical burden of operators through automated wire pulling operations, avoids unnecessary displacement caused by fatigue, and ensures the stability of the operation process and the accuracy of the basket position.
[0014] (3) Effectively resist displacement caused by wind: Wind is a key external factor affecting the stability of the hanging basket. This system is designed with a set of fast-response automatic wire pulling mechanism that can monitor the position changes of the hanging basket in real time and make rapid adjustments to resist the influence of wind, ensuring that the hanging basket always remains in the predetermined safe position during the test.
[0015] (4) Ensure the accuracy of high-voltage tests: The central control console ensures the accuracy of key measurement parameters in high-voltage tests by precisely controlling the distance between the hanging basket and the simulated wires on both sides. The system's automated monitoring and adjustment functions eliminate the interference of human factors on test accuracy and improve the reliability and repeatability of test results.
