Summer Summer Summer Power Supply ｜ People's Daily: Robotics successfully repairs the carrier -ranging line

At the site of the 750 kV Maibao Ⅱ line, accompanied by the State Grid Shaanxi ultra -high -voltage company, the drone operating player Wang Hao reported "the eighth card repair completion, the ground line repair is successful" Repair the work of the ground line of ultra -high -voltage AC transmission lines is successfully completed. This work not only broke the key difficulty of the power operation of ultra -high -voltage AC transmission lines, but also opened up a new space for the further development of ultra -high -voltage transmission lines.

State Grid Shaanxi ultra -high -pressure company developed to repair smart robots used to repair the overhead floor disconnected stocks

Disposal streaming of overhead grounds in the mountainous area has always been a major problem in the field of power transmission and maintenance. It often needs to be performed by the line. This greatly reduces the reliability of the power grid. Because the ground wire is often at the highest point of the iron tower, it is a single root. Witnesses, difficulty in boarding and high safety risks. In 2020, the emergence of intelligent repair robots in the first generation of ground line solved this national problem. However, due to the communication lines compared to the DC line, the induction current and the strong electric field interference in the robot are very large, resulting in the robot that can only solve DCAC The problem of the operation of the line is undoubtedly a technical difficulty that needs to break through. After two years of unremitting efforts and overcoming difficulties, State Grid Shaanxi Electric has finally successfully developed a version 2.0 ground -line intelligent repair robot based on the first intelligent repair robot of the ground line, solving the land of super high -voltage AC transmission lines Line repair problem.

State Grid Shaanxi ultra -high -pressure company transmission and maintenance personnel jointly work together to hang robots

The scene of the charging operation of Maibao II is also the first actual test of this innovative result. During the job, first hang the robot to the overhead ground hanging point, and then make a simple installation by the personnel on the tower. After the robot is installed on the ground line, the ground operator is issued by the ground operator. The robot begins to climb the ground line to move. On the way, the anti -vibration hammer is successfully shifted to the operating point of more than 480 meters from the tower material. Dead corner monitoring, conducting segments, successfully completed the task of charging operations, and then returned to the hanging point by itself. So far, the work is successfully completed.

In the next step, State Grid Shaanxi Electric Power will continue to work hard, actively try new ideas, explore new methods, continuously improve the technical level of electricity operations, enhance the reliability of power grids, and contribute to the construction of an internationally leading energy Internet company with Chinese characteristics.
