| Abstract: | The force and dynamic characteristics of emergency trip device for compact turbine are analyzed in this paper. The characteristics of off-center pole, pressured spring and trip device of three procedure （before and after trip, restore） are obtained. The law of the height of gasket with trip rotate speed is calculated. All the work is the basis for the safety of the turbine. |
