Abstract: The goal of "emission peak and carbon neutrality" has stimulated an extensive interest in the research and development of high-voltage vacuum interrupters. In this paper, the possibility of applying the six-slot cup-shaped axial magnetic field (AMF) contact in the high-voltage vacuum interrupter is explored by increasing the slotted rotation angle on the cup wall. The results show that increasing the slotted rotation angle is an effective means to enhance the AMF of the gap of the six-slot cup-shaped AMF contact at a large gap. What's more, properly increasing the contact cup height and thickness not only leads to a significant decrease in the contact resistance, but also enables the slotted rotation angle to be further increased, which means that the AMF can continue to be strengthened. Finally, the addition of supports can obviously increase the strength of the contact structure with a larger slotted rotation angle, and the decrease of the AMF of the contact gap is not obvious. Overall, the research results of this paper can provide reference for the practical application of the cup-shaped AMF contact in the high-voltage vacuum interrupter.
