Abstract With the steady development and advancement of 3D grid construction, the current planar visualization of optical fiber loops in smart substations in limited to the information reading and fault location of optical fiber loops for secondary maintenance,which has been unable to meet the operation and maintenance requirements of secondary maintenance for smart substations. At the same time, key technologies such as 3D modeling of secondary systems for smart substations are lacking, and advanced applications related to 3D scenes are lacking. Status quo. This paper proposes rapid imaging of 3D models and automatic wiring technology to realize 3D panoramic visualization of the secondary loop of smart substations. A 3D model library of secondary objects is constructed by the Unity 3D engine. The SPCD model file extends attribute information such as cable loops, terminal strips, hard pressure plates, and three-dimensional model interfaces to achieve the completeness and interactivity of the power supply equipment model information. The three-dimensional panoramic display reverse analysis technology is used to realize the three-dimensional model of the secondary system of the intelligent substation. Real-time visualization, and interaction display of cable loops, optical fiber loops, logic loops, and equipment information in three-dimensional scenes, filling the gaps in the configuration, interaction, and display of three-dimensional models in the field of secondary power distribution systems. The integration of the three-dimensional design results of the power grid with the secondary system has expanded the application space of the three-dimensional model of the secondary system, and has been applied in the pilot project of 110kV Fengqi transformer substation in Bozhou, Xinjiang.

Key words： transformer substation secondary circuit 3D model library panoramic visualization
