| Abstract: | The paper introduc, ed the various fault conditions and their handling method of switching-off and switching-in ting and threephase un-syncbronization for SF6 circuit breaker, such as the bubble existed in oil channel of hydraulic manipuiator of circuit breaker, un- synchronization of switching-off and switching-in time caused by exceed route and obstructed pulling lever of circuit beaker etc.. And the items that should be paid attention to when measuring are put forward. |
