High Voltage Breaker Cam Actuator’s Optimization Design on the Virtual Prototype Technology
In this paper, the virtual prototype technology is used for the analyzing and optimizing high voltage breaker actuator’s cam machine. While the high voltage breaker closing, the moving contactor can have the perfect dynamic property by the optimal data. The contactor’s dynamic property curve should be in line with perfect dynamic property curve. The velocity curve can be gotten by analyzing virtual prototype. According to the theory of high voltage breaker’s dynamic property, a smooth voltage curve can be fitted. This fitting curve as the perfect voltage curve can be used for optimizing the cam machine. Supposing other work condition is invariable, the key points on cam profile which decide the dynamic property of the cam machine are analyzed. The coordinates of the key points are optimized and the cam profile is amended. Analyzing the dynamic property of the breaker’s virtual prototype with the amended cam machine, the contactor’s dynamic property curve is perfect. In this paper, the optimal coordinates of the key points are used on the cam profile, and the high voltage breaker actuator’s cam machine is optimal.
