The mechanical properties of the vacuum circuit breaker can directly influence the realization of its electrical properties. In view of the vacuum circuit breaker operating mechanism, this paper will elaborate on the function of Disc Spring on over-travel rod and make a multi-objective optimization design of it. In the process of optimization, the simple genetic algorithm was improved through adjusting the crossover probability and mutation probability, the second crossover, the specified gene mutation and the immigration strategy, and shortcomings when the simple genetic algorithm came into immature convergence were also easily overcome. Through comparing the optimization result and calculation efficiency of the traditional Matlab algorithm, the simple genetic algorithm and the improved genetic algorithm, the superiority of the improved genetic algorithm was verified. Meanwhile, the optimization result was experimented in the laboratory. Results showed that using the improved genetic algorithm for disc spring optimization design was feasible and effective, and the theoretical basis of optimization design for disc spring was provided as well.

This paper analyzes the advantages of double breaks under series connection for 126kV HV vacuum circuit breaker. It makes efforts in the break designing to avoid hidden danger brought by voltage-sharing capacitor. Voltage is evenly distributed in the shape of ▸ at the basic break that asks for no voltage-sharing capacitors. Permanent magnetic actuator is used to ensure the synchronization of opening and closing of double breaks. Based on this layout, this paper designs a new actuator and motion system for vacuum circuit breaker optimized by virtual prototype software ADAMS and genetic algorithm. Laboratory tests have proved that the opening and closing speed of the breaker meets the speed standard and that the 126kV HV vacuum circuit breaker is feasible. © 2014 SERSC.
