Abstract

The GCB(gas-insulated circuit breaker) is very important in power system and is driven by a SOM(spring operating mechanism). During the operating of the GCB and SOM, a heavy load is applied at high speed, and many parts are broken, cracked, and deformed. Since each part in GCB and SOM are connected, it is difficult to know the exact load history. For this reason, endurance life test is required for a lot of time and labor. Therefore, the fatigue endurance analysis must be accompanied when the initial GCB and SOM design. This study performs fatigue endurance analysis on key parts such as Mainlever Roller and Cylinder Rod in GCB and SOM by using the DAFUL of multi-body dynamics program.
