1D-CAE による電力用ガス遮断器ばね操作機構の開発

抄録

A spring-operating mechanism for high-voltage gas-circuit breaker has been developing. The simulation by using 1D-CAE method is carried out for this mechanism. The pneumatics, rigid body, spring, hydraulics and solenoid are modeled with each functional icon placed in the united simulation system. We confirmed good accuracy in plus or minus 5 percent for the simulation and the experiment on the prototype design. This simulation can also be applied for three pole gang-operated mechanism. Each motion of the pole is not in sync because the torsion of main shaft appear strongly. The parametric study for the designs has performed. Finally, the design of mechanism with the auxiliary damper was obtained.
