Abstract

The existing research on axial magnetic field (AMF) contacts in vacuum interrupters mostly focuses on power frequency or low current conditions and lacks in-depth optimization of magnetic field characteristics and contact structure parameters under short-circuit current impact. Therefore, the AMF characteristics of the vacuum interrupter under short-circuit current excitation are studied, and the contact structure parameters are optimized. Firstly, a three-dimensional transient electromagnetic field model of the vacuum interrupter, excited by the measured short-circuit current, is constructed, and the effects of four key geometric parameters - contact slotting angle, cup finger angle, slotting length, and slotting width - on the peak AMF are quantified. Secondly, the orthogonal test method is used to screen significant factors, and it is concluded that cup finger angle is the most critical parameter among the four. Finally, a quadratic regression model is constructed by combining the response surface model (RSM) to explore parameter interactions. The theoretical optimum is obtained and further refined through boundary verification to yield the actual optimal parameter combination. This study guides the design of AMF contacts in vacuum circuit breakers under short-circuit conditions.
