Abstract |
SF_6 gas circuit breakers we widely used for short circuit current interruption in EHV or UHV power system. For a SF_6 gas circuit breaker development, the hot gas velocity measurement is necessary during SF_6 gas circuit breaker's trip operation. Small-gap flashover characteristics are used for this hot gas velocity measurement. This study sho was the hot gas velocity measurement results during SF_6 gas circuit breaker' trip operation. |
