Spring actuators are one of the key parts in circuit breakers.Their functions directly affect the performances of circuit breakers.A finite element model of the spring is established with ANSYS software in this paper
and the stress distribution induced by impact load in the keeping-spring of a spring actuator is analyzed based on the finite element model.The simulation results agree well with the practical situation.In addition
the fatigue of the keeping-spring is investigated.The analyzing method and results can be applied to the design and maintenance of spring actuators in circuit breakers.
