We have constructed CAE (Computer-Aided-Engineering) system of SF6 gas circuit breaker (GCB) development and design. This system combines organically electrical field analysis, arc analysis, gas flow analysis, and so on, which can analyze dynamic interrupting phenomena.
The GCB interrupting phenomena are generally of two types, namely, small current interrupting phenomenon and high current interrupting phenomenon.
This CAE system integrates some of the analysis of interrupting performance which are small current interrupting, short-line-fault current interrupting, and terminal fault curret interrupting. We can almost use common data of every analysis and simulate interrupting performance of actual GCB during development steps.
This technology contributes directly to highly accurate development, shortened development steps, and further improvements in the reliability, interrupting performance, and functions of GCB. It helps to identify new problems encountered in upgrading GCB and in building important technologies for developing the new high power and high voltage GCB.
