The virtual prototype technology is applied to smulating the high voltage switch’s working process and optimizing the stiffness of the moving contact’s buffer spring.When high voltage switch closing
the bump creates the bounce between the contactors.The high-voltage arc happen between the contactors
as create the accident of the switch and reduce the life of the switch.By optimizing the stiffness of the contactors’ buffer spring
the results of the contactors’ colliding can be amended very well
and the dynamic property of switch closing can be improved.
