This paper proposes and applies an ultra-high-voltage converter transformer automatic inspection technology

which comprehensively replaces the traditional on-site inspection methods of personnel

realizing panoramic interaction of information in the converter transformer region

intelligent replacement of manual inspection

full control of operators

and automatic warning of hidden risks. The command decision-making is accurate and efficient

further improving the level of equipment and personnel management and control of the converter station

and building the foundation for the subsequent construction of intelligent converter stations.
