Simulation analysis on reducing the electric field stress at the triple junctions & on the insulator surface of the high voltage vacuum interrupters

Internal electric field modification method based on region segmentation for vacuum interrupters

“…However, if the VI is inappropriately designed, the high‐temperature arc may damage the surface of contacts and even lead to the failure of rupturing current. Hence, a study of electric field design for VIs is of great significance [4–7].…”
