Research on characteristic analysis and construction method of 3D digital model of power transmission and transformation equipment

Combined with the status quo of the digital model of power transmission and transformation equipment, the basic characteristics of the three-dimensional digital model of power transmission and transformation equipment are studied. The main types of power transmission and transformation equipment are introduced. Considering the different states of power transmission and transformation equipment at different stages, the design, construction, operation and maintenance stages are analyzed. The relationship between power transmission and transformation equipment models in design, construction, operation and maintenance stages is studied. The space transformation method of the transmission and transformation multi-medium heterogeneous model is analyzed, together with the model position and orientation registration method. Finally, take the construction of three-dimensional model of transmission line as an example to build the basic unit of the model. The model units are combined and assembled orderly as a whole project. Safety distance collision verification analysis between models can be realized conveniently.
