Abstract

This paper proposes a fault analysis method for a spring-type operating mechanism of vacuum circuit breaker. For operating mechanism of FZW-type vacuum breaker

its 3D solid model is built with Solidworks. Then the determination methods of spring stiffness coefficient and damping are described

and the parameters of spring and other components of operating mechanism are determined. Finally

each of the main components of movement and forces are obtained from kinematics simulation of operating mechanism

and the fault of spring-type operating mechanism were analysed as well as preventive measures. The results show that the kinematics simulation analysis to actual model of spring-type operating mechanism can be as reference to fault analysis of vacuum circuit breaker.
