N2 - Contactors are widely used in the field of automatic control. The main contact rebound is one of the main reasons for its premature failure. Especially at the high voltage level, the small contact gaps caused by the main contact rebounds during contactor releasing will lead to a higher risk of arc restriking, which even will burn the product. Therefore, in the process of contactor design, it is necessary to minimize the rebound amplitude of the main contact release. This paper takes a type of high-power DC double breakpoint contactor as the research object. Established a dynamic model of the moving contact in the release rebound process and verified the model's accuracy through experiment and simulation. Based on the model, the effects of contact gap, contact overtravel, moving contact mass, spring stiffness and other factors on the release rebound time and rebound amplitude are investigated, and the results are of reference value for optimizing the structural design of the contactor and suppressing the contact release rebound.
