Analysis and treatment of the spring operating mechanism stored energy faults in circuit breaker;

Analysis of the breaker rejecting movement accident caused by a spring mechanism manual/electromotion changeover switch fault

This article firstly put forward the calculation formula on static opening speed for SF_6 circuit breaker with spring mechanism.

In electric power system,the main operation mechanism of high voltage circuit breaker are hydraulic circuit and spring mechanism.

In this dissertation, we focus the work on the execute mechanism of the trajectory correction rocket grenade, which is one of the key technology.

The executive mechanism of Cu-Al pipe butt welder,based on above,was designed,including its air system and mating clamper.

In order to improve the running smoothness of mesh-belt and reduce the wear between mesh-belt and traction wheel, on the base of completing the design scheme of mechanical system in heat treatment furnace with mesh-belt conveyer, the dimension synthesis of the executive mechanism is accomplished and the main sizes of the mechanism are given.

For the swinging cylinder type of hydraulic wrench, through the analysis and calculation for the locating parameters of its executive mechanism, formula and design precondition of the locating parameters are presented, with which the minimum of pushing force of the oil cylinder can be achieved under definite swinging angle and given loosening & tightening torque for the fasteners.
