Technical Field

[0001] The invention relates to the technical field of GIS buffer maintenance, and in particular to a method for repairing an ultra-high voltage GIS buffer. Background Art

[0002] Although the existing operation and maintenance mode can effectively avoid the omission of operation items, it lacks correlation in data such as on-site viewing of equipment information, implementation monitoring of equipment status, effective evaluation of equipment performance, intuitive visualization of technical principles, standardization of maintenance processes, and technical requirements and standards.
