Optimal Design of Insulation of 3.6kV Vacuum Interrupter

Abstract

This paper compares and analyzes the insulation structure of the vacuum interrupter, focusing on the influence of the mechanical characteristics and the structure of the shield on the insulation, and establishes an electric field calculation model for the axisymmetric structure of the vacuum interrupter. Finally, the radius of the conductive rod and the thickness of the contact are compared and optimized, and then the thickness of the shield is compared and calculated, and then simulated and analyzed with ANSYS software to verify the optimization direction.
