Abstract: At present, China's power grid is accelerating its transformation in the integration of big data, artificial intelligence cloud platform and other new technologies with the main network operation and maintenance business. Maintaining the safe and stable operation of overhead transmission lines and ensuring the reliable supply of electricity are the top priority of power enterprises. In terms of troubleshooting the defects of the overhead transmission line and the hidden dangers of the channel, the traditional manual inspection can no longer meet the requirements in terms of technology, regulations and specifications. It is necessary to use new technical means to replace or supplement the current inspection methods,such as new power transmission line inspection methods using drones, helicopters, and intelligent control platforms, to comprehensively improve production quality and efficiency and ensure the safe operation of the power grid.
