Abstract：Linkage transfer phenomenon, which exists in the opening process of the operating mechanism of moulded case circuit breaker (MCCB), is introduced. Influence of the linkage transfer position on the performance of the mechanism is analyzed. According to the analysis result, an optimum design is made for the linkage transfer position of a certain operating mechanism with virtual prototype software ADAMS. Simulation and experimental results show that after optimization the operating time of the mechanism is shortened about 1ms. The analysis result can provide guideline for improving performance of the mechanism by optimizing the linkage transfer position.
