Automated Three-Dimensional Construction and Electrical Field Calculation of Basin-Type Insulators

In Gas Insulated Switchgear (GIS), basin-type insulators serve as critical components, providing both insulation support and sealing functions. Due to their complex geometrical structure, these insulators are highly sensitive to electrical field distribution under extreme operating conditions. The details of the geometric model directly influence the concentration and uniformity of the electrical field, making optimized design essential for improving insulation performance and preventing flashover and breakdown. To address the issue of automatic annotation of the geometric model's physical properties, this paper proposes a refined construction method for basin-type insulators based on the integration of 3D reconstruction and numerical simulation. The results show that the proposed automated reconstruction method can effectively calculate the electric field distribution, providing a new avenue for electrical field simulation and design optimization of basin-type insulators.
