N2 - Optical fiber is widely used in power systems, and partial discharge of optical fiber occasionally occurs during normal operation, resulting in signal transmission interruption and insulation performance degradation. In this paper, the electric field simulation analysis is carried out for the structure of the end flange of the optical fiber insulator, indicates that the electrical strength inside the flange reaches 0.48 kV/mm, higher than the average electrical field strength of 0.15 kV/mm. The electric field distribution in the flange of materials with different resistivity and size is studied, and the electric field strength of the interface between the materials inside the flange is taken as the optimization goal. By using Random Focus Search Algorithm, electrical field strength is reduced to 0.12 kV/mm, and the optimal resistivity material parameters and flange size structure of the optical fiber insulator are obtained.
