Analysis of a Fast Acting Circuit Breaker Mechanism, Part II : Thermal and Mechanical Aspects

In an accompanying paper the authors have already presented ented an analysis of certain electrical aspects of a model elecneticallyromag- etically driven circuit breaker mechanism. Similar mechanisms have been used in recent years to develop fast acting high voltage circuit breakers. This paper presents an analysis of important thermal and mechanical design parameters. Classical concepts of mechanics and heat, with appropriate numerical techniques, are utilised in the analysis presented here.
