The research and analysis of the transfer of 3D design results is critical in power transmission and transformation engineering, however it has an issue with erroneous performance positioning. The typical 3D modeling technology is unable to address the research and analysis issue in power transmission and transformation engineering, and the result is insufficient. As a result, a Data mining techniques-based research and analysis of three-dimensional design results of power transmission and transformation engineering is provided, and Research and analysis of three-dimensional design results of power transmission and transformation engineering is assessed. To begin, the data set theory is used to discover the influencing elements, and the indicators are split based on the research and analysis of the transfer of 3D design result’s needs to decrease interference factors in the research and analysis of the transfer of 3D design results. The data set theory is then used to create a Data mining techniques research and analysis of the transfer of 3D design results scheme, and the outcomes of the research and analysis of the transfer of 3D design results are thoroughly examined. The MATLAB simulation results reveal that, under particular evaluation conditions, the Data mining techniques outperforms the standard 3D modeling technology in terms of research and analysis of the transfer of 3D design results accuracy and time of influencing variables.
