要約(英語): The scope of application of vacuum circuit breakers is being expanded as an environment-friendly electric power device for carbon neutrality. Since the energy of the actuator increases as with the breaking capacity increases, it is important to properly evaluate the mechanical durability due to the switching operation impact in order to improve the reliability of the product. Accordingly, this research devised a method for evaluating component damage due to switching operation impact. It is necessary to evaluate the influence of switching operation impact on component damage by considering the frequency of the impact acceleration not only by the peak value of the acceleration. Evaluation by the damage boundary curve defined by the maximum acceleration and the velocity change of the component is applicable. By applying this method, it is possible to prevent damage to circuit breaker components and avoid cost increase due to overdesign.
