For vacuum circuit breaker with spring operating mechanism
an optimum design of cam mechanism is significant to make the output force characteristics match the load characteristics. The cam mechanism is designed based on the output force characteristics and the principle that the output force should be higher than the resistance force. The sectional polynomial method is also used in design. The theoretical calculation coincides with the experimental result
which shows that the method is feasible for optimum design of spring operating mechanism.
